IMHO, I believe FWD, RWD and AWD have their advantages depending on the surface and track. For drag racing, RWD is the choice for drag racers running less than 8's. On dirt, gravel and snow nothing beats AWD. On twisty asphalt, a properly prepared FWD will dominate AWD and RWD. That was seen in WRC when Citroen dominated with FWD before they went AWD on the asphalt events. So it really dependent on the type event that really determines the "weapon of choice".
