20 Aug 2008 Bob Lutz and the GM Volt
Here is a nice Charlie Rose interview with Bob Lutz, talking about the ideas and progress of the GM Volt. It’s about 56 minutes long.
One of the things mentioned (at about 41 minutes in) is that the show car had a drag coefficient of about 0.43, which was too much – it reduced the range to 35 miles instead of 40. The new design has a drag coefficient of about 0.28.
