Chevy Volt Production Design

Up to 40 miles Battery ELECTRIC DRIVE Hundreds of miles EXTENDED RANGE Driving (Gasoline or E85)

Volt IS an... Extended-Range Electric Vehicle without range anxiety The Volt operates on battery power alone up to 40 miles without using gas or producing emissions It uses electricity to move the wheels at all times and speeds The engine generator provides electricity to power the drive unit for extended-range capability It plugs into a standard household 120V outlet or 240V for charging

Optimizing the shape of the Volt Balance aerodynamic performance & styling Functional, efficient, fun-to-drive Minimize aero drag to maximize battery range Air moves easily around the car

Balance between aerodynamic performance and styling Rounded, flushed front fascia, closed grille, aerodynamically shaped side mirror, sharp rear edges and a purposefully designed spoiler allow the air to stay attached and then detach quickly at the rear to reduce drag

Designed from the inside out Blend of form & function Cutting-edge features, surprising intuitiveness Comfort, convenience and safety features that customers expect in a four-passenger sedan Human/machine interface enhancement was the priority leveraging ideas from consumer electronics products Feedback provided to driver to improve efficiency

High-tech aesthetic... Warm and inviting Driver-configurable instrument display/cluster 7-inch touch screen navigation/vehicle information display Touch-sensitive climate and infotainment controls Optional navigation system with an onboard hard drive for maps and music storage Standard Bluetooth for cellular phone and USB / Bluetooth for music streaming

Creating a new propulsion category: Extended-Range Electric Vehicle

Typical Commute Why Target 40 Miles?  40 Miles Is the Key Based on U.S. Department of Transportation 2003 Omnibus Household Survey
