General Motors Chevrolet Volt Production Show Car 2011

The Chevrolet Volt Production Show Car was unveiled at Detroit Renaissance Center by Chairman Rick Wagoner, Vice Chairman Bob Lutz and President Fritz Henderson. "Revealing the production version of the Chevy Volt is a great way to open our second century," said Rick Wagoner, GM Chairman and CEO. "The Volt is symbolic of GM's strong commitment to the future... just the kind of technology innovation that our industry needs to respond to today's and tomorrow's energy and environmental challenges ."

General Motor has established a new GM Studio dedicated to the company's next generation of electrically driven vehicles. GM's new E-Flex Systems Design Studio will develop a variety of vehicles using the E-Flex propulsion system, starting with the production version of the Chevrolet Volt. It is the only studio specifically dedicated to design a wide variety of electric plug-in vehicles with a range extender.

E-Flex System developed by General Motor is a new propulsion system for fully electric propulsion vehicles. The E-Flex system comprises a set of lithium-ion batteries that power the electric motor for a range of approximately 40 miles( 64 kilometres). The E-Flex system is a plug-in technique meaning that the batteries can me charge on conventional 120 Volt electric outlet or on 240 Volt outlet. The E-Flex system integrates a so called range extender that produces electric power to recharge the batteries on the road and allow for further hundreds miles range; the range extender can be a conventional combustion engine running on gasoline, ethanol E85 blends, a Diesel unit, or later an hydrogen fuel cell. For the Chevrolet Volt , 220 lithium-ion cells contained within the Volt's T-shaped battery pack provides ample power. The Volt's electric drive unit delivers the equivalent of 150 horsepower, 273 lb-ft (370 Nm) of instant torque, providing a top speed of 100 miles per hour. GM estimates that the Volt will cost about two cents per mile to drive under battery power compared to 12 cents per mile using gasoline priced at $3.60 per gallon (compared to 10 cents per kWh on the grid). The Chevrolet Volt battery can be charged in eight hours on a standard household 120 Volt outlet or in less than three hours on a 240 Volt outlet.

One of the key task for GM engineers is integrating the T-shaped lithium-ion battery into the vehicle structure and developing new computer testing procedure; this advanced computer program duplicates real-life vehicle speed and cargo-carrying conditions, and compresses 10 years of comprehensive battery testing into Volt's brisk development schedule. The battery cycling equipment is used around the clock in GM test facilities in Warren Michigan. and Mainz-Kastel, Germany. It charges and discharges power from the prototype batteries based on the Volt's approximately 40-mile (64 kilometres) electric-only drive cycle. Results from this test data will help predict the long-term durability of the battery. Testing the batteries in the laboratory provides a predictable environment to compare technologies under controllable situations. The batteries will also be integrated into "mule" or test vehicles with other E-Flex system components for on-road tests.

"Extensive analysis in our battery labs is an important step in proving this technology. We expect to further validate these batteries when they are integrated into engineering development vehicles," said Frank Weber, global vehicle chief engineer, Chevrolet Volt and E-Flex systems. "The conditions in a vehicle - where the battery is exposed to shaking, moisture and rapidly changing temperature conditions- are much more extreme than the controlled settings of the lab."

Engineering an electric with a battery roughly 6 feet long (1.8 m) and weighing more than 375 pounds (170 kg) requires innovation. The T-shaped battery will be located down the center tunnel of the vehicle and under the rear seats. This integration requires the battery to be treated as part of the vehicle structure. "the battery is more than just an energy carrier; it is a structural component that affects many other aspects of the vehicle," said Frank Weber. "It's an integral part of the vehicle that interacts with the vehicle's thermal and safety systems and chassis components.

Working closely with GM aerodynamicists to shape the production Volt, design and engineering teams developed a fully aerodynamic evolution of the 2007 Chevrolet Volt Concept car. They spent hundreds of hours with the Volt in GM's wind tunnel, testing and re-testing parts such as the front and rear quarter panels, rear spoiler, rockers and side mirrors.

Inside, the Chevrolet Volt offers the space, comfort, convenience and safety features that customers expect in a four passenger sedan. Modern controls and attractive materials, two information displays, and a touch-sensitive infotainment center with integrated shifter distinguish the Volt's interior from other vehicles in the market.

Specifications: five door, front wheel drive sedan for four passengers. Extended Range Electric Vehicle. Top speed 100 miles per hour. Power 111 kW (150 hp), torque 273 lb-ft (370 Nm). Length 440 cm (177 in.) width 180 cm (70.8 in.) Height 143 cm (56.3 in.) Wheelbase 268 cm (105.7 in.)
