Mercedes B55 Concept

Spacious, innovative and safe, the compact models of the Mercedes A and B-Class score with their high practicality, and have found favour with more than 2.5 million customers as a result. An extraordinary one-off example has now been built at the Rastatt plant, and shows the B-Class in a completely new light: a B55 with a V8 engine and rear-wheel drive.

The idea came from the Rastatt plant manager, Peter Wesp. He gave some of his staff the task of creating a very special vehicle on the basis of the B-Class - leaving it to their creativity to decide what and how. Andreas Würz, a foreman in the technical vocational training department, immediately took up the challenge. He took a very close look at this large compact model, enlisted the aid of a tape-measure and came up with an idea that not only surprised and delighted his boss and colleagues, but also the trainees: "Actually it should be possible to fit a V8 into the engine compartment."
Together with his fellow-foreman Matthias Rieger from the electrics/electronics installation section, he assembled a team of twelve second-year and third-year trainees specialising in production mechanics and automotive mechatronics.
A book of specifications was drawn up:

• The spatial concept of the B-Class was to remain unchanged.
• On the outside too, there were only to be minor indications of the conversion work.
• The interior was to be upgraded in line with the new vehicle class being aspired to.
• And the result of the conversion was to be in large measure suitable for day-to-day driving.HR manager Martin Spicale promised financial support, which made the project a feasible proposition in the first place. And a "victim" (Würz) for the conversion was also soon found: a B 200 CDI which had anyway been delegated to the training workshop for learning purposes. While the trainees completely disassembled the car, Würz went in search of a suitable engine and found what he was looking for. And no mistake: the 5.5-litre V8 developing 285 kW (388 hp) and 530 newton metres of torque was transplanted into the B-Class together with a seven-speed automatic transmission and the engine control unit. The latter proved to be quite a headache later on, as it had to be reprogrammed only to process signals from the driven rear axle.
  Würz: "The V8 power unit fitted amazingly well, and we were even able to use the original engine mounts." There were serious problems with the steering, but here too, harmony was restored with a number of modifications. The exhaust system was a clever combination of various replacement part items, and took the form of a twin-pipe system emerging at the centre of the rear end. This is where the one-off, christened the B55 gets its typical, burbling sound - once the ignition key has been turned, all heads in the vicinity are guaranteed to swivel simultaneously in the direction of the B-Class.
  Intensive perusal of parts catalogues also solved the second major transplantation problem, namely the drive axle at the rear. It emerged that the rear axle of an older W 210 series E-Class would be a very good geometrical fit. Plant manager Wesp gave the go-ahead to obtain one, and Würz and his colleagues designed a subframe, which extensive forming and welding work allowed to be integrated into the B-Class bodyshell to receive the new rear axle. Elegantly concealed within the sandwich floor, the propshaft of the E-Class also fitted into the B-Class with no further modifications.
  For the brakes the team also struck gold in the replacement parts catalogue, this time in the C32 AMG listing. Perforated and internally ventilated disc brakes in size 345 x 34 mm were implanted at the front, with perforated and internally ventilated disc brakes in size 300 x 30 mm at the rear. The system was combined with striking 8.5 x 18 AMG sports wheels in a five-spoke design shod with 235/40 ZR 18 Y tyres at the front and 9 x 18 wheels with 255/35 ZR 18 Y tyres at the rear. The maximum steering angle at the front axle was limited to suit. The team had recourse to a typical item from the tuner's toolbox for the suspension, installing a coil-over suspension by K&W.
  Where the interior was concerned, friends from the training workshop in Sindelfingen were able to help, providing Alcantara linings for the A, B and C-pillars as well as a roof liner in the same, luxurious material. The seats in a leather/Alcantara combination were provided by the specialists at Johnson Controls, who are located on-site in Rastatt. The finishing touches were added to the B55 in the paint shop of the Rastatt plant. In trendy white with dark-painted radiator louvres and smoked headlamp lenses, the B-Class cuts an imposing figure but only gives a discreet indication of the powerpack concealed beneath its bonnet.
  The project team headed by foreman Würz are particularly proud that at 1620 kg, the weight of the B55 is only around 180 kg greater than that of the original car. Which means that impressive performance figures can be expected. Würz: "We have not made any measurements yet, but we should manage a sprint to 100 km/h in under six seconds."
  Plant manager Wesp is equally proud of the result: "The team of trainees has done a superb job, and placed a spotlight on the sporty genes of the B-Class that nobody could have imagined." Training manageress Manuela Rascher is likewise very pleased: "The B55 shows what our training workshop can do. And at the same time it clearly demonstrates that we not only offer young people high-quality professional training, but also highly unusual and exciting project work." Could it be that further projects of this nature are planned for the future? Rascher: "We may have some surprises in store…"

Chevrolet Camaro ZL1

The 2012 Chevrolet Camaro ZL1 debuted at the 2011 Chicago Auto Show. It is the highest-performing Camaro and the most technically advanced car ever developed in its class. The new ZL1 continues the momentum of Camaro, propelling it into an entirely new realm of leading-edge performance technology. It is planned to launch at the beginning of 2012.

Motivated by a supercharged V-8 engine producing an estimated 550 horsepower (410 kW), the Camaro ZL1 will be the fastest Camaro ever offered by Chevrolet. And more than just power, the ZL1 features technologically advanced and highly developed chassis and suspension systems that help it deliver balanced, track-ready handling and braking power to complement its high engine output. Rigorous development of the ZL1 is ongoing, and official estimates of the car’s capabilities will be released later in 2011, as testing nears completion.
“Camaro ZL1 is about high-tech performance and design, and is a type of car no one has ever brought to this segment previously,” said Rick Scheidt, vice president of Chevrolet marketing. “It’s the most technically advanced Camaro ever, so we’ve chosen a name from the most elite and exclusive Camaro in history.”
The ZL1 name is derived from the all-aluminum racing engine of the same name, which was developed in the late 1960s and installed into a handful of regular-production 1969 Camaros. Only 69 were built with the engine, but they’ve achieved mythical status among enthusiasts, as they represented the pinnacle in Camaro performance – until now. The 2012 ZL1 model is designed to be a major leap forward for the Camaro, bringing a new level of performance capability to the segment.

The central goal of the car’s development was creating something new – a Camaro intended to reach optimal lap times on top road-racing circuits and excellent driving dynamics on the street. To achieve that goal, engineers evolved many of the existing Camaro’s systems, as well as incorporated new technologies such as electric power steering and Magnetic Ride Control, the world’s fastest-reacting suspension system.
Camaro ZL1’s design communicates and supports its performance mission. Rather than using decorative elements, ZL1 is visually differentiated from other current Camaro models with elements vital to the car’s elevated capabilities.
“Everything about the ZL1’s design is directly related to its technology and serious performance, especially aerodynamics,” said Ed Welburn, vice president, Global Design. “Our designers’ goal was to execute that function-oriented design with beautifully sculpted forms, creating an imposing, powerful persona. Function becomes the aesthetic. The intent is a car that delivers on the attitude it projects.”
Major elements of the ZL1’s design are a new front fascia and hood with air extractors, designed in tandem to create aerodynamic downforce to aid handling. The car’s hood includes a signature center section constructed of carbon fiber and rendered in satin black finish. New rocker panels, wide tires, 20-inch wheels and exhaust tips portray the car’s handling and power.
The ZL1 badge appears on the grille, hood and the brake calipers, all key areas portraying the technology within.
Tech overview.
Supporting the dynamic track and street performance of the ZL1 is the LSA 6.2L supercharged engine, which will produce an estimated 550 horsepower (410kW) and 550 lb.-ft. of torque (677 Nm), with specific features for the Camaro. Built on GM’s legendary all-aluminum, small-block V-8 architecture, the LSA features an intercooled supercharger system, premium heat-resistant aluminum-alloy cylinder heads and other details designed to ensure its exceptional performance is delivered with smoothness and refinement. Components and design elements that contribute to the LSA’s performance include:
• Balanced, lightweight reciprocating assembly
• High-strength hypereutectic pistons
• Sixth-generation Eaton supercharger with four-lobe rotors
• Piston oil squirters.
Because the Camaro ZL1 uses electric power steering, the engine does not incorporate a conventional hydraulic power steering pump on its accessory drive system. This enhances performance, because no engine power is used to turn a steering pump pulley.
Camaro ZL1 is a complete high-performance car, not just a Camaro with more power. Key technical highlights include:
Transmission – The high-performance Tremec TR-6060 six-speed manual is matched with the LSA engine. It is the “MG9” version of the transmission, with a higher torque capacity. It is used with a dual-mass flywheel and twin-disc clutch for easy operation and shift smoothness. A new, shorter-throw shifter actuates the gear changes.
Exhaust – ZL1 is equipped with a dual-mode exhaust system, which alters the sound level and character in response to engine rpm. First used on the legendary Corvette, and specifically tuned for Camaro ZL1, the dual-mode exhaust will give the car a signature sound.
Drivetrain – It is revised with a stronger driveshaft and rear axle system, featuring a larger and stronger cast iron differential housing, stronger axles and heavy-duty limited-slip differential. This patent-pending system is designed to ensure that ZL1’s tremendous power is delivered smoothly to the ground.
Suspension – The suspension features completely revised tuning and the inclusion of segment-exclusive Magnetic Ride Control. ZL1’s Magnetic Ride system will include driver selectable modes (Tour and Sport) tailored for the preferred style of driving. It uses advanced magneto-rheological science to produce shock damping with the highest level of precision, enabling body control optimized for excellent performance in everyday driving as well as track situations. This technology appears on only a small roster of some of the world’s finest performance cars. Other chassis elements are redesigned to support the car’s high-performance limits. Rear stabilizer bars have drop links repositioned outboard of the control arms. This makes the bars more effective in controlling body roll in turns, with crisp response to driver commands.
Brakes and Steering – Camaro ZL1 features an advanced track-capable braking system, developed in conjunction with experts from Brembo. The large 14.6-inch (370 mm) two-piece front rotors have six-piston calipers; the 14.4-inch (365 mm) rear rotors have four-piston calipers. ZL1 marks the entry of a new electric power steering system to Camaro. It is being developed to ensure precise control and feedback to the driver, with greater variability of effort for high-performance driving.
Exterior – ZL1’s signature from the front is the redesigned fascia and aluminum hood with a raised, carbon fiber insert. The fascia includes a front splitter and new vertical fog lamps. The fog lamp area includes air intakes designed for brake cooling. The hood features front-mounted air extractors that direct air precisely over the car. Visually, this center section, in satin black carbon fiber, communicates the car’s high-performance intent as a visual contrast to the car’s exterior color. Functionally, the air extractor is a key in connecting airflow closely to the bodywork, creating aerodynamic downforce. The carbon fiber center section reduces the mass of the hood. High-intensity discharge (HID) headlamps and fog lamps are standard. The rear of the car includes a diffuser and spoiler, also functional elements that enhance the car’s aerodynamics.
Wheels and Tires – New-design, 20-inch forged aluminum wheels, which are lighter than the 20-inch wheels used on the Camaro SS, are used with new Goodyear Supercar F2 ties developed specifically for the ZL1.
Interior – ZL1 is tailored for high-performance driving. The front seats feature microfiber suede inserts. Other enhancements include a redesigned steering wheel, alloy pedals, Head-Up Display with unique performance readouts and the “four-pack” auxiliary gauge system featuring a boost readout.
Production details.
All of the Camaro exterior colors will be offered with the ZL1, but black is the only interior color. The unique exterior features are complemented with a black center section on the hood. Inside, the Camaro ZL1 has heated leather seats with microfiber inserts and ZL1 logos embroidered on the front headrests. Microfiber suede is repeated as an accent on the instrument panel, adding a richer look to the interior. The ZL1 will include the same content as the current 2SS package and include the following new or unique features:
• Six-way power driver and passenger seats
• Unique instrument panel and door panel inserts; and ZL1-logo sill plates
• Steering wheel audio controls with Bluetooth capability
• Wireless PDIM and USB-port
• Boston Acoustics premium audio system
• Rear parking assist
• Rear camera system (displayed in the inside rearview mirror).
Engineers have already driven Camaro ZL1 prototypes extensively at demanding road courses in the U.S. and Germany, with final testing being completed through the balance of 2011.

Chevrolet Camaro 45th Anniversary Edition

Chevrolet Camaro, America's most popular sports car, extends its momentum with enhancements for the 2012 model year. Highlights include an improved version of its standard 3.6L direct injection V-6 engine, a new FE4 performance suspension package for SS coupes and several interior and technology improvements, such as a revised instrument panel design, new steering wheel and rear camera system.
The enhancements arrive in time for Camaro's 45th birthday, which will be celebrated with the release of the Chevrolet Camaro 45th Anniversary Special Edition. Continuing the tradition of Camaro anniversary models, the 45th Anniversary Special Edition carries all the upgrades for 2012, with additional unique design elements, inside and out.

"The appeal of Camaro design and performance has powered it to the top of its segment," said Rick Scheidt, vice president of Chevrolet marketing. "For 2012, we're capitalizing on that momentum with enhancements to Camaro's performance and comfort."
Also coming in early 2012 is the high-performance Camaro ZL1, the most technologically advanced car ever developed in its segment.
Class-leading 3.6L V-6 engine
Camaro's new 3.6L direct injection V-6 - the LFX engine - goes into production in the summer of 2011. It delivers an SAE-certified 323 horsepower (241 kW) at 6,800 rpm - an increase of 11 horsepower (8 kW) over the 2011 engine, with no compromise in fuel economy.

Chevrolet Cruze Hatchback

The story of the Chevrolet Cruze goes from strength to strength with the latest chapter heralding the launch of a new Chevrolet Cruze hatchback model, further evidence of Chevrolet's intention to bring value for money to all mainstream segments in Europe.
A show car version of Chevrolet's compact contender will be seen for the first time at the 2010 Paris Motor Show, on September 30. It will be one of four world Chevrolet premieres at the show.

With the introduction of the new Chevrolet Cruze hatchback, customers have an alternative body style to the traditional sedan and Chevrolet has raised the bar again with a vehicle that brings new levels of value against some of the more established competition.
According to Wayne Brannon, president and managing director of Chevrolet Europe, the potential for meeting further customer demand is significant. "Cruze is turning out to be a real success story. We are selling it in 70 countries around the world and it has recently surpassed the Aveo as our top selling passenger car nameplate globally.
"Hatchbacks play a critical role in many markets. The total compact segment in Europe represents around 4.8 million units which is over a quarter of the total market, with hatchbacks representing around 65% of that volume. We therefore expect to see increased business in a number of regions, while sending out a signal that Chevrolet is now a serious mainstream player in Europe."
Since its launch in the spring 2009, the Chevrolet Cruze sedan has been warmly welcomed by markets all over the world, greeted as a step change for the brand with customers attracted to its coupe style, build quality, 5-star NCAP rating and driving dynamics. It was also elected the AUTOBEST car of 2010 by a jury of leading auto writers in Central and Eastern Europe.
The Chevrolet Cruze is a car particularly well suited to European driver tastes, a fact borne out by sales success across many of markets. So far in 2010, Chevrolet Cruze tops the compact sedan sales charts in many of the larger European markets including Denmark, Germany, Switzerland, Italy, Spain, Portugal and the U.K., where it is exceeding forecasted sales.

Outside of Europe, Chevrolet Cruze's sales momentum is equally evident. In China alone, Chevrolet has sold nearly 90,000 Cruze since the start of the year, while the sedan is also selling well in Russia, parts of South America, and in India and other emerging markets.
Hatchback design
With its attractive sweeping coupe roofline and short overhangs at both the front and rear, the new Chevrolet Cruze hatchback has the same dynamic 'stance' as the sedan and will be instantly recognizable. It will benefit too from the same taut body 'feel' on the road, being built using the new body-frame integral system (BFI) which is complemented by the final tuning to chassis components. The BFI system results in high levels of stability and solidity.
Cargo capacity for the Chevrolet Cruze hatchback is close to 400 liters and will feature 60/40 split rear seating.
Chevrolet's participation in the World Touring Car Championship with the Chevrolet Cruze is also currently paying great dividends. With four races left in the season, it currently leads both the drivers' and team championships while also showcasing the dynamic qualities of the car to great effect.
The new Chevrolet Cruze 5-door hatchback will go on sale across Europe mid 2011 with prices announced nearer the launch date.

Chevrolet Captiva

The new Captiva SUV will be seen for the first time at the Paris Motor Show, sporting a new front end design, a range of enhancements to the interior and new engines and transmissions. Captiva will be one of four Chevrolet world premieres.

Captiva is Chevrolet's full-blooded sports SUV with confident and dynamic new styling and active on-demand all-wheel drive system that distributes power as needed.

At the same time the new Captiva retains the advantages of its adaptable, theatre-style seating in three rows which comfortably accommodates up to seven passengers.

The Captiva has won many friends for its exterior design since its launch in 2006, and with the new model it just got even better. A number of features are immediately noticeable when viewing the new Captiva from the front, adding up to its athletic stance: the re-shaped and sharply sculptured hood, a new larger grille with its dual-opening and the Chevrolet 'bow-tie' sited proudly in the middle, and the prism style headlamps and integrated LED turn signals on the outside rearview mirrors.

Moving round to the front fenders, the side air-vents now take on a more angular shape to emphasize the new Captiva's sporting intent, while from the A pillars back the Captiva retains its handsome profile, characterized by a sleek, rising shoulder line.

Setting the new Captiva's body off perfectly are the new exterior color palette and the accentuated wheel arches which will accommodate wheel sizes of 17 to 19 inches.

It's under the Captiva's new hood that many changes are also taking place, with no less than four new powerful engines that will come standard with a new manual or automatic six-speed transmission for a powerful, smooth ride. The new engine line-up, which is comprised of two gasoline engines (2.4L and 3.0L) and two turbo-diesel variants (2.2L), incorporates a host of advanced technologies aimed at delivering an optimal balance of performance and fuel economy.

With the introduction of a new 3.0 liter 258 hp V6 gasoline engine with direct injection and variable valve timing, the Captiva will be one of the most powerful compact SUVs on the market, while the new 2.2 liter common rail turbo-charged diesel units will be available with either 163 or 184 hp outputs. Rounding off the new line-up is a 2.4 liter dual overhead cam gasoline unit with variable valve timing, rated at 171 hp. Both, the 2.2 liter turbo-diesels as well as the 2.4 liter gasoline engine can be ordered in front- or all-wheel-drive configurations.

The new Captiva's chassis has been re-tuned to further enhance vehicle dynamics, improving cornering, roll characteristics and ride feel. With Electronic Stability Control (ESC), Traction Control System (TCS) and Braking Assist System (BAS) standard, as well as front-, side- and curtain airbags, the Captiva provides a high level of safety.

Climb aboard the new Captiva and driver and passengers will still be welcomed by that airy and spacious interior, with storage space that is among best in class and with the option of either 5 or 7 seats.

The Captiva's upgraded interior now features an array of new finishes and textures including all-new seat fabrics and interior décor appointments to give the car a more up-market feel and look. Designers have put to good use some of the elements featured on other new Chevrolet models, such as the ice-blue back lighting and the 'wrap-round' design of the front fascia which flows into the front driver's and passenger doors creating the dual-cockpit look.

The new Captiva features Hill Start Assist, eliminating 'roll-back' on hills and an electric park brake that opens up space for further storage in the center console, including two 1-liter cup holders.

The new Captiva's audio system includes Aux-in, USB-port and Bluetooth connectivity. Passengers will enjoy their audio experience all the more thanks to improved acoustic engineering resulting in reduced road, wind and engine noise. Captiva can be ordered with a touch-screen navigation system with rear view camera for parking assistance.

Captiva offers a lot of SUV for its price: powerful, yet efficient engines, all-wheel drive capabilities, roominess and versatility for up to seven passengers. Its launch in Europe is scheduled for spring 2011.

Concept Jakusa Bossco

Confused the concept of this car? Glance, would look like the Chevrolet Camaro and Ford Mustang 5. Jakusa Bossco developed by Tamas Jakus, the same designer who came up with supercars Revelation Triango currently being built in Hungary.

The shape and style of this Bossco Jakusa unabashedly inspired by the muscle cars like the Mustang Boss 302. However, rather than overtly retro, which have a strong sense Bossco and futurism. Bossco imaging concept can be seen looking from the side lights are similar to the one Land Rover in the movie Judge Dredd.

Size Jakusa Bossco concept is similar to the Camaro, which means it's a pretty big vehicle, and it requires a machine large enough and strong frame. Jakus has also been suggested that this car will use a V6 engine with 600 horsepower. to the wheels will be using alloy wheels measuring 21 inches.

Chevrolet Colorado Rally Concept

At the 2011 Buenos Aires International Auto Show, Chevrolet revealed the Colorado Rally, a second show truck version of its next generation global midsize pickup. The debut of the adventure themed vehicle follows the reveal of the first Colorado show truck at the Bangkok Motor Show in April 2011. "Both trucks give a glimpse of the next generation Chevrolet global midsize pickup, which is of huge importance to consumers in

many countries around the world. For example, in Brazil, costumers made Chevrolet's midsize truck the vehicle segment leader for 16 consecutive years," said Brad Merkel, GM Global Vehicle Line Executive.
Chevrolet's unmatched heritage in durable and dependable pickup trucks is exemplified in the Colorado Rally's sturdy and robust appearance. The show truck combines signature design elements with Chevrolet's legendary on and off road capabilities.
"Colorado Rally exhibits Chevrolet's DNA in an off road version. To develop this vehicle we did an extensive research on the off- road Motorsport. Each and every detail was deeply studied in order to deliver maximum authenticity, designed with the rally raid category in mind, also known as cross country rallying", says Carlos Barba, GM South America Design Center director.

Chevrolet Colorado Rally Concept is a crew cab version with a tridimensional front grille featuring chromed details. Outfitted wildly, Colorado Rally's body color is a triple coat pearled White with golden particles, and other external components in textured charcoal. Skid plate and side moldings in liquid metal and bead lock off road wheels milled from a single piece of aluminium. The wheels machined from a single piece of aluminium, with two distinct surface finishing (machined and polished), 18" inch diameter, and Mud-Terrain T/A 305/60R18 tires to "attack" the off road's obstacles.

Ergonomics, safety and functionality set the Interior's theme
Designers focused on ergonomics, safety and functionality to create the Chevrolet Colorado Rally Concept's interior, such as the high performance steering wheel, designed for an aggressive handling, with a tighter (than a production model) curvature in the upper and lower arcs. The upper arc has LEDs integrated to the bar designed as a quick display tachometer. The side grips have two buttons on each side facing the driver, they are; high beam toggle, menu display for the cluster to change the displayed information, "Air Boost" control, and speed limiter for urban sections of a race.
The interior colour trims, like the plastic components, leather covered upper instrument panel, are textured in "Very dark ash grey". The center stack has some inserts in metallic satin finishing. All commands are finished with soft touch materials and to make it more practical and sporty, the seat materials and the steering wheel cover are in black neoprene with orange stitching, and a high depth "Rashel" effect fabric in orange with black under colour. Metal mats in "very dark ash grey" with orange rubber inserts, roll cage and other metal details painted in silver and reflective orange details on the door reinforces the detailed interior design. The metallic mat is positioned a few millimeters from the floor, perforated with integrated rubber details designed to help clean the occupants' footwear and provide a higher grip.
In terms of safety and functionality, Chevrolet Colorado Rally has the Internal roll cage with custom railing profile, developed to provide an attaching system to additional equipment, such as cameras or auxiliary lighting. The 5-point seat belt directly connected to the Roll cage.
Vehicle integrated fire extinguisher activated through the IP, releases flame suppressing foam to the cabin and engine compartment, and plus two traditional fire extinguishing canisters positioned between the seats right behind the center console. The master switch integrated to the center stack, with two key functions, starting the engine, disconnects every system in the vehicle, in case of emergencies. For off road chases before overtaking other competitors during a race, there's the "Air boost" highly compressed air system developed to quickly clean the cabin after entering a dust cloud.
To be able to face high temperatures inside the cabin during the race, Chevrolet Colorado Rally has a Hydration pack, which consists of dedicated containers for feeding and hydrating positioned behind each seat, the food solution is delivered to the occupant's through a small tube system.
Other features are the first aid kit stored in the center console and three dedicated tool boxes locked in the area behind the seats, being one for each occupant, containing the most used tools, and a third box in the center dedicated to specialized tools for harder jobs.
To keep the racers in the right track the concept vehicle has a Sat Nat, satellite navigation positioned directly in front of the navigator. Maps, sign plates, and road books are stored into the glove box and also fixated through bungee cords on the outside of the glove box access door. Communication devices for internal and external contact, center stack with gauges for temperature and pressure, as well as commands for adjustment of the suspension system, tire pressure regulator, fire extinguisher activation, and two separate commands for the fuel pumps and a tripmeter display are also part of the high featured equipment.

Chevrolet Miray Concept

GM Korea introduced the Chevrolet Miray Concept at the 2011 Seoul Motor Show. The roadster celebrates Chevrolet's 100-year heritage of designing stunning vehicles in the brand's newest market.

According to GM Korea President and CEO Mike Arcamone, "'Miray' is Korean for 'future.' As GM rolls out Chevrolet across Korea, the Miray concept offers an exploration of future possibilities for the brand. It strengthens the bond between car and driver, creating a fresh look at what sports cars of the future might be."
The Chevrolet Miray Concept was developed at the GM Advanced Design Studio in Seoul. Combining cutting-edge hybrid powertrain technology and advanced styling, it balances iconic Chevrolet design cues with a future design vision as Chevrolet celebrates its centenn
ial in 2011.
Classic Exterior
The Miray pays tribute to Chevrolet's sports car heritage. It is small and open like the 1963 Monza SS, and light and purposeful like the 1962 Corvair Super Spyder. Its expressive, aerodynamic fuselage is reminiscent of modern jet fighters.
Made of carbon fiber and CFRP (carbon fiber-reinforced plastic), the wedged body side is divided by an angled character line, with ambient lighting underneath. This accent creates a sweeping line of light when the car is in motion, bringing a warm glow to the sculptured body. Le Mans racer-style scissor doors open up and out of the way for dramatic access to the interior.
The powerful front end offers a reinterpretation of the Chevrolet face. The Chevrolet Miray Concept's dual port grille is flanked by LED headlamps with new signature daytime running lamps. The front and rear fenders evoke Chevrolet Corvettes of the past and express the concept's sports car spirit. At the corners, carbon-fiber spoilers help control down force and airflow.

Distinctive retractable flaps provide additional airflow control while providing access to the charge port on one side and the fuel filler on the other. The charge port also features an external battery charge indicator. Each rear fender contains individual cargo space for the storage of small items. Under the ducktail surface, the taillamps provide a new interpretation of Chevrolet's twin element identity.
The Chevrolet Miray Concept features aluminum-carbon fiber composite 20-inch wheels in front and 21-inch wheels in the rear. The strong turbine theme evokes movement, even when the Miray is stationary.
The heavily tapered top view enhances the Miray's purposeful image. From above, the cabin has a unique diamond shape.
Sporty Interior
The interior of the Miray echoes Chevrolet's racing heritage. As with the exterior, it takes inspiration from jet fighters. The Chevrolet Miray Concept contains a melange of brushed aluminum, natural leather, white fabric and liquid metal surfaces, for an overall effect of sculptural velocity.
The interior compartment is surrounded by a carbon fiber shell, which gives it a lightweight yet rigid structure. Its flowing, yet slightly tensioned, twin cockpit tightly wraps around the driver and passenger. The cockpit is driver focused, drawing inspiration from the iconic Chevrolet sports car. However, the passenger is also fully engaged in the driving experience.
Asymmetric seats flow from the door, forming a symmetric interior that gives the driver a feeling of being fully connected with the car. Ambient lighting, which starts from the upper instrument panel and flows into the seat back area, adds a sense of luxury. Seat cushions and headrests are connected by the lightweight carbon fiber shell and mounted on a single aluminum rail. The headrest area follows the exterior form, integrating with an air scarf for open-air driving.
Designers took a unique approach to displaying information, using back projection on the instrument panel. Information in front of the driver has been prioritized into three zones. Immediately in front is vehicle performance. It is flanked on the left by range and on the right by navigation and mileage figures. This eliminates unnecessary visual clutter, allowing the driver to focus on the thrill of driving.
The center touch screen flows down to an aluminum support, which evokes a fighter jet's nose with the landing gear down. The exterior surface waterfalls down into the interior to meet the reinforced console, connecting the front and rear of the car.
The centrally located start button is also inspired by a jet aircraft. When the button is pressed, the column-mounted retractable meter cluster rises like a jet fighter canopy and "Interactive Projection" appears on the white surface.
Retractable rearview cameras, which replace traditional rearview mirrors, extend from the side glass electrically. In city driving, the forward-facing camera operates in conjunction with GPS to overlay navigation information with real-time video.
Fuel-Efficient, High-Performance Propulsion System
The Chevrolet Miray Concept features a concept "mid-electric" propulsion system, located primarily behind and beneath the driver, that maximizes performance and fuel efficiency.
"Many of the components in the Miray's propulsion system are a logical extension of GM's current technology portfolio," said Uwe Grebe, executive director for GM Powertrain Advanced Engineering. "The concept shows the potential for reconfiguring, rescaling and extending today's propulsion technologies."
The Chevrolet Miray Concept is propelled by two front-mounted 15-kW electric motors for quick acceleration and zero emissions in urban driving. The motors are powered by a 1.6-kWh lithium-ion battery that is charged through regenerative braking energy. The Miray has the capability of being switched from front-wheel drive to rear-wheel drive.
For performance driving, the Chevrolet Miray Concept's 1.5-liter four-cylinder turbocharged engine combines with the electric motors, providing spirited torque control to both the left and right wheels as needed. The high-tech engine, mounted behind the cockpit, drives the rear wheels while seamlessly integrating electrification technology that defines a new standard in the compact roadster segment.
A dual-clutch transmission (DCT) enables a reduction in the powertrain's size by eliminating the torque converter. Shifts are quick and firm. The shift pattern has been tuned for improved top speed in performance mode. A start-stop system works in conjunction with the DCT.

"The propulsion concept fits perfectly with the rest of the vehicle, delivering big performance in a small footprint, on the road and in the environment," said Arcamone. "By combining GM propulsion technology and visionary design, the Chevrolet Miray Concept points to the future of Chevrolets around the globe - expressive, youthful and entertaining."

Chevrolet Silverado

On a validation drive of the new, 2011 Chevrolet Silverado HD heavy-duty trucks, engineer Brent Deep towed a 20,000-pound (9,072 kg) trailer for 245 miles (400 km) along I-70 between Denver and Grand Junction, Colo. - and he barely touched the brakes the entire way.

Deep relied on the Chevrolet Silverado's new, smart exhaust brake system to slow the truck/trailer combination on descents, helping prove the new system is suitable for the most demanding
conditions. It was a drive across the heart of the Rocky Mountains and some of the interstate system's steepest grades, with altitudes ranging from Denver's approximately 5,000 feet (1,525 m) to more than 11,100 feet (3,400 m) at the Eisenhower Tunnel.

"It takes some courage to leave your foot off the brake, but the Chevrolet Silverado's Duramax engine and Allison transmission perform the task with smoothness and confidence that really impresses," said Deep. "Better still, the exhaust brake system can help extend brake pad life and help avoid overheating the brakes on long descents."
The exhaust brake system feature is just one of the elements that makes the new 2011 Chevrolet Silverado 2500HD and 3500HD models the most capable in the industry. They go on sale this summer.
"We sought the input of our customers during the development of the 2011 Chevrolet Silverado HD to deliver a truck that meets or exceeds their every need," said Jim Campbell, Chevrolet general manager. "It offers greater strength and capability - including class-leading fuel economy, trailering and payload ratings - and has more power, accelerates quicker and has lower emissions. That sounds like the very definition of no compromises."
The Chevrolet Silverado HD heavy-duty lineup is broader than ever, with 11 2500HD models and eight single- and dual-rear-wheel 3500HD models - including a new 3500HD Crew Cab with a 6.5-foot cargo box. WT, LT and LTZ trim levels are offered, and popular features such as the EZ Lift tailgate and rearview camera system return. All models bring greater capability, improved ride and handling and a greater feeling of driver control. Depending on the model:

• Segment-best fifth-wheel towing capacity of 20,000 pounds (9,072 kg)
• Segment-best conventional towing capacity increases up to 23 percent, with a maximum of 16,000 pounds (7,272 kg)
• Segment-best payload capability of 6,335 pounds (2,873 kg) on a complete vehicle
• Segment-best Gross Combined Weight Rating increases to 27,500 pounds (12,500 kg)
• Gross Vehicle Weight Ratings increases up to 17 percent to 13,000 pounds (5,909 kg)
• Front Axle Weight Rating increases by up to 25 percent to 6,000 pounds (2,721 kg)
• Snow plow capability is now enabled for all 4WD cab configurations

There are also enhanced powertrains, including a new Duramax 6.6L diesel/Allison 1000 six-speed transmission that offers the exhaust brake system, new front and rear suspensions, an improved brake system, hill start assist, trailer sway control system and more.
"Along with all their heavy-duty equipment, these trucks are designed to be stylish and refined, inside and out," said Campbell. "We paid close attention to all the details, giving them a distinctive, muscular appearance on the exterior and a well-appointed interior with the comfort, convenience and safety features customers appreciate."
Outside, the 2011 Silverado 2500HD and 3500HD models are distinguished by a power dome-style hood with a new, louvered design, as well as a new grille and full-width chrome steel front bumper. A new lineup of 17-, 18- and 20-inch wheel/tire combinations is featured, too (20-inch polished forged aluminum wheels are available on 2500HD).
Designers and engineers left almost no bolt unturned during the comprehensive redesign of the trucks. Here are 11 key elements that demonstrate the 2011 Chevrolet Silverado 2500HD and 3500HD are ready for any job and any competitor:
New frames
In the quest to comprehensively redesign the Chevrolet Silverado HD chassis to improve durability and ride, while also supporting increased capability, engineers developed 11 all-new, fully boxed frame assemblies. The frames have increased cross sections and use more high-strength steel for greater durability, higher towing capacity and improved ride and handling; the front sections are hydroformed.
The bending and beaming stiffness of the frames is increased 92 percent and 20 percent, respectively, with the fully boxed sections enhancing torsional stiffness by a factor of five. Also, larger engine and transmission mounts, coupled with a 125-percent-stiffer front frame structure, provide greater vibration control, while hydraulic body mounts are incorporated under the cab section on extended and crew cab models for a more isolated feel inside.
Engineers addressed common customer and aftermarket uses when designing the new frames, including adding access holes to the rear frame section to enable easier installation of fifth-wheel/gooseneck-style hitches. Also, the frame-mounted hitch for conventional trailering is stronger, with a box-tube design. It supports up to 16,000 pounds (7,257 kg).
New and strong independent front suspension

A completely redesigned independent front suspension system offers up to a 25-percent greater front axle weight rating - up to 6,000 pounds (2,721 kg) front gross axle weight rating (FGAWR) - enabling a snow plow to be used on all 4WD cab configurations with the available snow plow prep package, while also supporting improved ride and handling characteristics.
Chevrolet Silverado's signature short-long arm/torsion bar front suspension design is retained, but now features new, forged steel upper control arms that are stronger and lighter than their predecessors. The new lower control arms are made of precision-machined cast iron to handle the greater loads. Five different torsion bar rates support five different front gross axle weight ratings (a single torsion bar was previously used for all models). This helps stabilize the range of trim heights of various models under load, while enhancing appearance, handling, durability, tire wear and alignment. The trim height is adjusted on each bar via a single bolt, easily allowing the height to be changed to account for the weight of a snow plow or other accessories.
The Chevrolet Silverado HD front suspension now uses a pair of urethane jounce bumpers on each side, instead of one, for improved load management; and there's a new upper shock mount attachment design that's positively connected to the frame with two fasteners. This design eliminates squeaks and clunks, while supporting higher load capability and increased durability.
Compared to competitors' beam-axle front suspension, the Silverado's independent front suspension provides a better ride, more accurate trim height control (with fewer parts) and greater flexibility to adjust the alignment for weight and tire sensitivity.
New asymmetrical leaf-spring rear suspension
Commensurate with the Chevrolet Silverado HD's greater strength and capability is a rear suspension designed to support greater loads. It features a new, larger asymmetrical leaf-spring design that also contributes to improved ride and handling characteristics.
The asymmetrical design is derived from unequal front and rear spring half lengths, which minimize axle hop and enhance traction control efficiency. 2500HD models feature a two-stage leaf-spring design, while 3500HD models have a three-stage design. All models feature 3-inch-wide (76 mm) leaf springs that are 20-percent wider than previous models.
The larger leaf-spring design supports increased rear gross axle weight ratings across the board. On the 2500HD models, the rating is 6,200 pounds (2,818 kg) - up from 6,084 (2,765). On 3500HD models, the rating increases to 7,050 pounds (3,204 kg) on single-rear-wheel models and 9,375 pounds (4,261 kg) on dual-rear-wheel models - the latter representing a nearly 14-percent increase over the previous 8,200-pound (3,727 kg) rating.
Segment-leading towing and payload capability
Stronger frames, suspension systems with greater weight ratings and enhanced powertrain systems contribute to the Chevy Silverado HD's class-leading towing and payload capability. The specifications charts included below outline capacities for each model and/or configuration, but here are the key facts:

• The maximum conventional (ball hitch) towing rating increases to 16,000 pounds (7,257 kg)
• A Silverado 3500HD crew cab/long box can tow up to 20,000 pounds (9,091 kg) with a fifth-wheel hitch. The 2010 Ram 3500 has a maximum rating of 17,600 pounds (8,000 kg) and the 2010 Ford F-350 is rated at a maximum of 18,800 pounds (8,545 kg). It should be noted that while Ford claimed segment-leading trailering and payload during its recent announcement of the 2011 Super Duty models, no towing ratings were issued
• The maximum payload (3500HD) is 6,335 pounds (2,873 kg) - that's nearly 11 percent greater than the 2010 Ford F-350's 5,730-pound (2,604 kg) rating and about 24 percent more than the 2010 Ram 3500's 5,130-pound (2,331 kg) ratings. Again, while claiming segment-leading payload for the 2011 Super Duty models, Ford did not announce the ratings

New 6.6L Duramax diesel and Allison 1000 six-speed combination
Helping the new 2011 Chevrolet Silverado HD trucks deliver their best-in-class capabilities is a new version of the workhorse Duramax 6.6L diesel and Allison 1000 six-speed automatic transmission powertrain combination. The Duramax 6.6L is more powerful and durable and the Allison 1000 is stronger and helps enable new features, including the exhaust brake system. Together, this improved version of a proven combination is also expected to deliver segment-best fuel economy.
The Duramax 6.6L's new and improved features include:

• Horsepower and torque expected to top previous model
• NOx emissions reduced at least 63 percent over 2010 models
• Quieter operation
• High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions
• Exhaust brake system that enables controlled vehicle slowdown on downhill grades without actuating the brakes
• Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance - with a range of about 5,000 miles (8,000 km) between DEF refills
• Combustion and after-treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations - a 75-percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel
• B20 biodiesel capability for an alternative fueling option
• Internal revisions that improve durability

With nearly 1.3 million Duramax 6.6L engines produced since 2000, they have proven exceptionally durable and dependable. The internal elements that helped build its reputation are enhanced for 2011, including:

• Main bearings' profiles changed to enhance oil film thickness
• Oil pump flow increased for increased pressure at low speeds
• The turbocharger's oil circuit is changed to provide increased pressure at the turbo and faster oil delivery
• The connecting rods' pin ends are modified to provide increased piston support
• New, higher-strength piston design that eliminates bushings to provide lower reciprocating weight
• An EGR cooler bypass reduces high-mileage soot deposits in the cooler and EGR circuit

The enhanced Allison 1000 for 2011 is strengthened to handle the higher torque capability of the new 6.6L Duramax engine, while also helping improve fuel economy and provide seamless assistance with a new exhaust brake system. Greater efficiency is delivered through reduced "spin loss" - meaning, the transmission channels more of the engine's power to the axles, allowing it to do more with less fuel.
The Allison 1000 also features driver shift control with tap up/tap down shifting and a patented elevated idle mode cab warm-up feature. Also, the tow/haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads. The six-speed configuration retains its two overdrive gears for optimal efficiency.
Performance with the Duramax/Allison combination is also improved over previous models, with preliminary testing showing 0-60 mph times of less than 9 seconds and quarter-mile times of less than 16 seconds in 2500HD models. That's about 0.3-second and 0.5-second quicker, respectively, than previous models.
Strengthened Vortec 6.0L/Hydra-Matic 6L90 six-speed powertrain
The venerable Vortec 6.0L gas V-8 with variable valve timing returns to the new heavy-duty trucks, along with a strengthened version of the Hydra-Matic 6L90 six-speed automatic transmission. This combination delivers excellent performance and efficiency, with a greater emphasis on low-rpm power.
A new camshaft profile in the Vortec 6.0L helps the engine produce more torque lower in the rpm band, for improved launch feel and a greater feeling of overall performance at higher altitudes and when towing a trailer.
The 6L90 is enhanced for greater strength, smoothness and quietness via:

• Adding four attachment bosses to the transfer case adapter (4WD models) for increased strength and smoother, quieter performance
• Increasing the cross section size of the transfer case adapter for greater strength
• Adding a new, stronger output shaft
• Adding a new heat shield and vent hose

Exhaust brake system
A new feature on Duramax-equipped models is an exhaust brake system. This driver-selectable feature uses the turbine control of the variable geometry turbocharger and the compression of the engine to generate backpressure, slowing the vehicle without applying the brakes. It is a smart system integrated with the cruise control feature and varies the braking to account for the grade and vehicle load.
The exhaust brake system allows for virtually effortless driving and towing, with seamless and quiet operation. It also helps prolong brake life and prevents overheating the brakes on long, downhill grades.
Large brakes
Brake feel and performance is greatly improved with the 2011 Silverado HD trucks. The standard four-wheel disc system is completely revamped to deliver smoother, more immediate and confident-feeling performance. Four-wheel, four-channel ABS is standard on all single-rear-wheel models and a three-channel system is standard on dual-rear-wheel models.
The front and rear rotors are larger in diameter - 14 inches (355 mm) - and width on all models to support their increased capacity, weight ratings and trailering ratings, while the calipers are stiffer and stronger. The hydroboost brake booster calibration is revised for reduced pedal effort and the travel of the pedal is also revised for a more comfortable, confident feel.
Larger wheel hub and bearing assemblies complement the new brake system and the rear rotors attach to the wheel hubs for easier servicing.
Refined and capable ride, handling and steering
Longer wheelbases - ranging from 133.6 inches (3,395 mm) to 167.7 inches (4,259 mm) - and wider front/rear tracks enhance the ride and handling characteristics of the Silverado 2500HD and 3500HD, giving them a greater feeling of smoothness and control.
The longer wheelbases and wider tracks are complemented by the new, stiffer frames, new jounce bumpers, shock mounts and hydraulic body mounts to provide a solid, smooth and isolated driving experience. New shocks were specially valved to support the new trucks' weight ratings, while balancing excellent ride characteristics.
Also enhancing the driving experience is a revised steering system designed to support the trucks' greater front gross axle weight rating. It includes a new, larger steering gear, power steering pumps and linkages. The pumps (different parts for gas and diesel models) deliver greater pressure for reduced steering effort in low-speed and parking maneuvers; they are also quieter. On some models, the new linkages feature a compliant joint added at the pitman attachment to enhance handling.
Comprehensive safety and functional technology
The 2011 Silverado 2500HD and 3500HD models have a comprehensive roster of safety features and functional technologies that include:

• StabiliTrak electronic stability control system on all single-rear-wheel models
• Larger, four-wheel disc brakes with standard four-wheel ABS
• A new high-strength steel tubular frame cross member that enhances safety and improves crashworthiness
• Seat pelvic/thorax and head curtain side air bags available on 2500HD
• Available rear backup camera
• Segment-exclusive OnStar 9.0
• Trailer sway control system on all single-rear-wheel models
• Hill start assist (standard on single-rear-wheel models)

Trailer sway control system provides an added measure of confidence when towing a trailer. The system senses conditions of trailer sway and intervenes with braking and/or reduced engine power to bring the trailer under control and keep it on its intended path. The system will use electric trailer brakes when a trailer is plugged into the standard wiring harness of the truck and its performance requires no input from the driver.
The hill start assist system is automatically engaged when sensors detect the vehicle is on grade of about 5 percent or greater. It holds the brakes for about 1.5 seconds or until the gas pedal is pressed, preventing rollback - it is particularly effective when towing, giving the driver time to switch from the brake pedal to the gas pedal without rolling.
Lives bigger, drives better, works harder
From the available remote starting feature to the unimpeded access offered by the 170-degree-opening rear access doors on extended cab models, the 2011 Chevy Silverado HD models live bigger, drive better and work harder. The interiors are refined, with improved quietness and attention to detail, but designed for working. Numerous storage compartments provide covered access for everything from work gloves to laptops.
Indeed, for many owners the Chevrolet Silverado HDs are mobile workspaces, offering mobile WiFi, USB connectivity, Bluetooth connectivity, XM Satellite Radio and a navigation system. Multiple charge points enable multiple electronic devices to operate simultaneously; and when equipped with the available navigation system, XM NavTraffic offers real-time updates of traffic conditions (in selected areas) that can help plan the most effective route to the job site.
Cold-weather customers will appreciate the Duramax 6.6L's quick, reliable start-up, with a starting time on par with gas engines. Its glow plug cycle time is the segment's best in all temperatures, taking no more than 3 seconds in temperatures as low as -20 F (-29 C). There's also a cab heat-up feature that allows the engine to idle faster in low temperatures to warm up the interior faster.
And when you're on the road, the Chevrolet Silverado HDs take you farther without stopping. A new, 36-gallon (136 L) fuel tank is standard on all models and, with the improved fuel efficiency of the powertrains, enables a cruising range of up about 680 miles (1,090 km) with the Duramax 6.6L. That's the equivalent of a trip from Houston to Oklahoma City and back to Dallas on a single tank.
Finally, all 2011 Silverado 2500HD and 3500HD trucks work under the best warranty coverage in America - five-year/100,000-mile limited powertrain warranty, plus roadside assistance, courtesy transportation and other features that provide assurance that Chevrolet backs its trucks confidently.

Chevrolet Volt

Chevrolet introduced the all-new, 2011 Volt electric vehicle with extended range, establishing an entirely new segment in the global automotive market. The five-door, four-passenger Chevrolet Volt is designed to provide the benefits of an electric vehicle without the range limitations associated with other electric vehicles in the market.

"The Chevrolet Volt can be the only car you own," said Mark Reuss, president, GM North America. "The Volt delivers it all: a revolutionary propulsion system, progressive styling, industry-leading safety, premium amenities and user-friendly technologies, and spirited driving dynamics."

Designed, engineered, built and delivered to customers in 29 months, the Chevy Volt will go on sale at Chevrolet dealers before the end of 2010. It is offered in one very well-equipped standard trim level, along with two option packages: a Premium Trim Package and a Rear Camera and Park Assist Package.
"The Chevrolet Volt makes the electric driving experience as productive, efficient, intuitive, safe and fun as any premium vehicle its size in the market today," said Doug Parks, Volt global vehicle line executive.
Every major element of the Chevrolet Volt was designed and analyzed for efficiency, including its highly aerodynamic exterior, lightweight wheels, specially designed tires, energy-saving premium stereo system, and more. This attention to detail makes the Volt one of the most aerodynamic and energy-efficient vehicles in the market.
The Chevy Volt redefines electric drive

The heart of the Chevrolet Volt is its Voltec propulsion system, which combines pure electric drive and an efficient, range-extending engine, giving to the Volt up to 350 total miles of range.
The Chevrolet Volt's long-life battery consists of a 5.5-foot, 435-pound (198.1 kg) T-shaped, 16-kWh lithium-ion battery pack manufactured in Brownstown Township, Mich. It supplies energy to an advanced, 111-kW (149-hp) electric drive unit to propel the vehicle. Using only the energy stored in the battery, the Volt delivers between 25 and 50 miles of fuel- and tailpipe emissions-free electric driving, depending on terrain, driving techniques and temperature.
The Chevrolet Volt battery is designed to deliver value, safety, quality, performance, durability and reliability. It is covered by an eight-year/100,000-mile warranty. Since 2007, GM engineers have completed more than one million miles and four million hours of validation testing of Volt battery packs, as well as each pack's nine modules and 288 prismatic cells. The development, validation and test teams have met thousands of specifications and validated each of the Volt battery's 161 components, 95 percent of which GM designed and engineered.
"Our customers are making a commitment to technology that will help reduce our dependence on petroleum," said Micky Bly, GM executive director, global electrical systems. "In turn, we commit to deliver the highest standards for value, safety, quality, performance and reliability to our customers."
When the battery energy is depleted, the Chevrolet Volt seamlessly transitions to extended-range mode. Power is inverted from a technically advanced, 1.4L 63-kW (84-hp) gasoline-powered onboard engine to the electric drive unit to provide up to 310 additional miles of range.
The Volt proves electric driving can be spirited. Not only does the Volt reach a top speed of 100 mph, the electric drive unit's excellent low speed torque of 273 lb.-ft. (368 Nm) takes it from 0 to 60 mph in less than 9.0 seconds and the quarter mile in less than 17.0 seconds.
Charging the Chevrolet Volt's battery is simple and intuitive, and can be done through 120V conventional household electrical outlets, or through a dedicated 240V charging station. The vehicle is completely rechargeable in about four hours using a 240V outlet and 10 to 12 hours in a 120V outlet. Once the vehicle is plugged in, owners can schedule either immediate or delayed charges, even coordinating charging according to departure time or when electricity rates are lower. Owners also can manage and monitor the Volt remotely via computer on MyVolt.com; or an exclusive smart phone application, Chevrolet Mobile App powered by OnStar MyLink.
The Chevrolet Volt is designed and refined to impress
The Chevrolet Volt's bold, sleek, performance-oriented stance conveys its electrically driven capabilities, and looks like an upscale, midsize sport sedan. This is made possible by its wide front and rear tracks (61.2 / 62.1 inches [1556 / 1578 mm]), 105.7-inch (2685 mm) wheelbase, wheels-out stance, sculpted belt line and premium execution.
"The Volt is a revolutionary car, and we wanted the design to make as sleek and dynamic a statement as possible," said Bob Boniface, director of design. "When you look at this car, it's very technical and refined in its execution, with lots of interrelating surfaces that bring clean, crisp edges and creases."
Working closely with aerodynamicists in GM's own wind tunnel to shape the Volt, design and engineering teams developed the most aerodynamic vehicle in Chevrolet's history. By reducing the energy needed to overcome air resistance, Chevrolet Volt aerodynamicists contributed an estimated eight miles of electric range, and 50 miles of extended range.

The Volt's rounded and flush front fascia, tapered corners and grille enable air to move easily around the car to reduce drag. In the rear, sharp edges and a carefully designed spoiler control air flow. An aggressive rake on the windshield and back glass also helps reduce turbulence and drag.
Inside and out, element-to-element gap and flush relationships are as good or better than any in the segment. Even the underhood compartment is not overlooked: All components are held to a high standard of appearance that harmonizes with the rest of the car, using similarly grained surfaces and colors.
The distinctive, gloss black rear liftgate appliqué carries the Chevrolet bowtie and one of two Volt insignias; the other is found on the forward quarter panel. Six exterior colors are offered on the Chevrolet Volt, including Viridian Joule Tricoat, the winning name chosen in a national contest held in 2009. The others are Silver Ice Metallic, Black and Cyber Gray Metallic, Crystal Red Metallic Tintcoat and White Diamond Tricoat.
Inside, the Volt offers the space, comfort, convenience and safety features that customers expect in a premium five-door sedan - including storage compartments and 40/40 rear-folding seats. It also delivers them in a variety of interior color, lighting and trim options unlike any offered before on a Chevrolet sedan, but with Chevrolet's signature dual cockpit design.
Two, seven-inch, high-resolution full-color screens are featured: One is a reconfigurable graphic cluster display and the other, in the center stack, features a touch screen display, touch-control switches and integrated shifter.
The graphics in the instrument panel and door inserts are repeated in the premium cloth or available leather-appointed seats. Bright silver appointments appear around the door switches, center cup holders, door pulls, centerstack switches and climate control outlets. Standard infotainment features include:

• Navigation radio with 60-GB (30 GB for music storage) hard disc drive, AM/FM/DVD-Rom/MP3 playback capability, voice recognition, Radio Data System, Bluetooth and pause-and-play radio functions
• XM Satellite Radio with XM NavTraffic/Weather, one of the industry's most advanced, real-time information systems
• Premium, energy-saving Bose audio system with six speakers and subwoofer
• Five years of OnStar Directions and Connections service.

In addition to enhancing safety and solidity, the Volt's stiff structure accommodates features that help to isolate engine and wind noise for a whisper-quiet cabin.
The Chevrolet Volt features excellent driving dynamics
Great driving dynamics begin with a solid body-frame-integral structure that enables optimal tuning and provides drivers with an enhanced sense of stability, solidity and confident road manners.
The Volt's MacPherson strut-type suspension, sophisticated compound crank rear axle and quick-reacting, rack-mounted electric power steering system with ZF steering gear - a feature commonly found on premium sport sedans - have been tuned to deliver a smooth, refined ride with responsive handling and solid, on-center feel. A low center of gravity combines with the wider track and long wheelbase for balanced performance, and front and rear hydraulic ride bushings, another premium addition, help eliminate road harshness.
The electro-hydraulic regenerative brake system captures energy up to 0.2g for transfer back to the battery. The friction braking system features large rotors with a special finishing process that protects against corrosion and promotes longer life.
The Chevrolet Volt rides on lightweight aluminum wheels that weigh only 17.8 pounds (8.1 kg) each, compared to 24.2 pounds (11 kg) for typical 17-inch wheels. They're wrapped in Goodyear Fuel Max all-season, low-rolling resistance tires optimized for electric vehicle range, noise, feel and performance.
The Volt features Chevrolet's continuous safety
Like all Chevrolet vehicles, the Volt helps protect occupants before, during and - thanks to OnStar - after a crash. Crash-avoidance features include standard anti-lock brakes with traction control, StabiliTrak electronic stability control and advanced, LED daytime running lamps that make the Chevrolet Volt more visible to other motorists and pedestrians.
Occupant protection continues with a strong structure, and the Chevrolet Volt's body-frame-integral structure strategically blends advanced steels to help ensure crashworthiness and stiffness. Nearly 80 percent of the Chevrolet Volt's overall structure consists either of high-strength, advanced high-strength or ultra high-strength steel. Active occupant protection features include eight standard air bags and safety belts with dual pretensioners to help reduce the risk of injury.
After a crash, the Chevrolet Volt offers the security of OnStar, which uses built-in vehicle sensors to automatically alert an OnStar advisor in certain types of collisions. The advisor is immediately connected to the vehicle and can request that emergency help be sent to its location.
Because the Chevrolet Volt operates so quietly in all-electric mode, a driver-activated feature sounds a noise to alert pedestrians, particularly those with visual impairments, in an intersection. The alert was developed in conjunction with the American Federation of the Blind.
The Volt connects with owners 24/7
There is much more technology inside the Chevrolet Volt than its electric propulsion system. Intuitive features such as high-resolution displays, connectivity and the ability to monitor and control vehicle functions remotely redefine how owners interface with their vehicles.
Key technologies include:

• Touch-control switch system on the center console
• High-resolution, seven-inch, full-color LCD reconfigurable Driver Information Center display. The display shows electric-only range, fuel economy, , extended-range, trip information, tire pressure information and other key vehicle messages.
• High-resolution, seven-inch, full-color, center stack-mounted touch screen display that serves as the interface for infotainment and cabin climate controls. An Efficiency (Leaf) switch accesses energy usage, power flow and charging screens - all easy to use and understand.
• Charge modes are customizable according to need and electricity rates for efficient programming and lower costs.
• A key fob that allows drivers to remotely start the vehicle and precondition the cabin based on outside temperatures
• An exclusive mobile app, powered by OnStar MyLink, that enables owners to engage with the Volt functions using a smart phone.

The Chevrolet Volt is in a class by itself
The Chevrolet Volt is not a hybrid. It is a one-of-a-kind, all-electrically driven vehicle designed and engineered to operate in all climates. Powered by GM's revolutionary Voltec propulsion system, it consists of a 16-kWh lithium-ion battery pack and electric drive unit that provide pure electric range between 25 and 50 miles, depending on terrain, driving techniques and temperature. A 1.4L gasoline-powered engine extends the range up to an additional 310 miles on a full tank of fuel by operating the vehicle's electric drive system until the car can be plugged in and recharged or refueled. This distinguishes the Volt from electric-only vehicles, which cannot be operated when recharging is not immediately available - such as during a power interruption or on a long-distance trip.
