I'd love to see some pics of this thing. I read some article the other day about a 250 MPG modified Honda Insight. Just ran on more batteries.
I'd rally one if it was given to me. I wouldn't rally it on my own dime for a multitude of reasons, a few of which Jens said, but the greatest being that I think new cars are too poorly and weakly built to withstand the abuse of rally, with the exception of a small, small handful, and even these are weaker than the cars of the 70s and 80s. Now a hybrid methanol Pike's Peak car on the other hand... People might show a little more interest in that. New Lexus V6 hybrid running on Methanol in a tube chassis with a full carbon Prius body and AWD drivetrain with old Celica or Corolla WRC tranny and diffs.
Hmmm. Maybe I can get these guys to build me a car for Pike's Peak that's a 4 second to 60 hybrid monster.
