We got our first sneak peek at the production Chevy Volt last week, but a recent presentation by Bob Boniface, director of design for the Volt, has revealed a bit more. We've pasted a video of the presentation and slide show after the break, and in it Boniface notes how the concept's straight lines and tight corners have been smoothed over and rounded out in an effort to reduce turbulence. This streamlining improves the Volt's fuel mileage, range on electricity and the amount of regenerative braking that can be captured. Also seen for the first time is a rear shot of the Volt, showing a pronounced "vertical fin," and a new rear spoiler design. Likewise, the side-view mirrors' mounting arrangement was revised for reduced aerodynamic drag. These changes, along with countless others which have not been fully revealed, have allowed the Volt's engineers and designers to increase EV-only range by six to seven miles.
While we're salivating over all the little tidbits of information on the Volt, we look forward to its official debut expected in Paris at the Motor Show this October. However, recent rumors indicate that the extended-range electric-vehicle could be seen at GM's Centennial celebration on September 16. Thanks for the tip, Emil!
