Other than using aluminum and carbon fiber, what are other cost effective ways to lighten a car and its platform? Can you perforate the frame with big holes like you see in construction I-beams and trusses? How about offering old fashioned hand crank windows for a bit of exercise and drop the weight of the motors? Can the frame rails be made thinner? Front wheel drive saves weight, right? I'm just curious if there is a systematic approach that could be used across the board to shave several hundred pounds off of GM's cars and truck.
