Here ya go for some SERIOUS power, very lightweight and true all-wheel drive: Turbine Electric. Stick a little Solar turbine in the engine compartment, route dual fat pipes for exhaust out the back and put gear-drive AC motors at each corner. If you don't want to convert the rear to IRS (handling!) just put a single AC motor right on the diff.

Just think of the whine, whoosh then roar when you start up! Plus you can run on diesel or kero and even feed raw fuel into the exhaust for an afterburner.
