Here is what the article said: "Driver behavior is clearly a factor for both traditional and electric cars. Beyond that, on traditional cars, factors like mass, aero drag and rolling resistance come into play in that order. In testing and simulation GM has found that for electrically-driven vehicles mass actually drops to third on the list behind aerodynamics and electrical loads with rolling resistance coming in fourth." Do you dispute this?[/quote]Mike756, from GM's comment that you quote above (last sentence) they're ranking for an EV is: 1) aerodynamics, 2) electrical loads, 3) mass & 4) rolling resistance. My guess is that they're weighing aero highest because of the fact the drag at 35 MPH (around town) will be only about 1/4th the drag at 70MPH (on the Interstate). Since the average buyer will focus primarily on the Volt's non-extended ELECTRICAL range, which will deteriorate much faster than a conventional car's range at 70MPH, aerodynamics indeed becomes a VERY important parameter!

And I'd LOVE the look of a big, flat, gold lightning bolt on that hood (where the Corvette winged emblem is on its long smooth hood, and instead of the Chevy Bow Tie)!
