I can't think of anything obvious either, but a Lotus Elise weighs roughly 1500 pounds and has a much more powerful engine, etcetera. It's even a completely street legal vehicle.* So, although I can't really think of anything, that extra weight must be in there somewhere.Delta Flyer said:How could it be lighter? Is there an easy way to make an aluminum frame and chassis lighter? Not trying to be contrary - just can't think of anything obvious.
