VIDEO: Aerodynamics adds 7 miles to Volt electric range

Back in the spring of 2008 when General Motors took us on a tour of its wind tunnel facility, chief engineer Frank Weber emphasized the importance of aerodynamics in maximizing the electric driving range of the Volt. At that time, all we got see was a one-third scale model covered in various colors of duct tape. However, GM's aerodynamicists, including Nina Tortosa, explained that even at lower speeds, resistance to air-flow played an even bigger part in efficiency than the car's mass. In the latest in a series of videos on the Volt ... Read more →
