Cd of 0.45? That seems a bit on the high side; I used 0.35 in my calculations but suspected it was a little optimistic. Do you have a source? I couldn't find any data on this.
As for weight, this site lists 1775 lbs dry. Perhaps not the best source.

Should be considerably less than 2300 lbs even with a driver and fuel. I would expect these guys to rip out most of the interior anyway.
Anyway, I listed all my #'s used, you can see from my plot that this site is calculating just 13.7 HP to maintain 60 mph, with all losses factored in.
Dremd, putting down 40 HP at 60 mph in almost any car would give acceleration.
In the end I think we can all agree that this thing is going to hit it's mileage target with ease. Provided they tune it properly once they start going after power mods; Dave, did you get rocketchip on board? I want to see some well documented dyno testing!
