the thing about fwd is that it, from a performance point of view, is not as good as rwd. when you accelerate the car "squats" so it shifts weight to the read wheels. this removes weight from the front wheels and you lose traction easier. that means you cant accelerate as quickly off the line or coming out of a corner. also, it means that the steering, the majority of the braking, and the aceleration are all done with the font wheels. that's mroe wear on them, which means more frequent pits, and lost time.
the reason that they are in cars is that it's easier to build, cheaper to build, and might be mroe efficient. that, from a road car point of view, is a great reason to build one.
