Volt IS an...Extended-Range Electric Vehiclewithout 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 timesand 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 performanceand styling

• Rounded, flushed frontfascia, closed grille,aerodynamically shaped sidemirror, sharp rear edges anda purposefully designedspoiler allow the air to stay attached and then detachquickly at the rear to reduce drag

Designed from the inside out

• Blend of form & function

• Cutting-edge features,surprising intuitiveness

• Comfort, convenienceand safety features thatcustomers expect in afour-passenger sedan

• Human/machine interfaceenhancement was the priority leveraging ideas from consumer electronics products

• Feedback provided to driver to improve efficiency
