4WD beats some RWD
I just saw a Road Test around a track on BBCs "Top Gear". The Mitsubishi Lancer EVO VIII out-performed the Mercedes SL55 AMG amongst others. (This is a car with more horsepower getting beaten by a car with less and 4WD) NOTE: The fastest were RWD Mid-Engined Lightweight Roadsters.
While, RWD will generally be better (i.e. F1 cars, LeMans, et.al) because of it's weight, it is not necessarily true the that it is the best all the time. Remember when the 4WD Skylines were dominating races. And the current 4WDs dominating the Rally's.
My car is 4WD, yes it is heavier than most, but I wouldn't be without it.
My Order of Drive Train to Overall Road/Race Performance would be this.
Mid Engine - RWD (e.g. F1 and LeMans, Ferrari, et.al.)
Mid Engine - 4WD (e.g. RS200, Peugeot 205 Turbo 16, Lancia Delta S4)
Rear Engine - 4WD (e.g. Porsche 959, Turbo)
Front Engine - 4WD (e.g. WRC Rally Cars)
Front Engine - RWD (e.g. GTs, Coupes, et.al)
Front Engine - FWD (e.g. Hot Hatches and Sporty Coupes)
