RWD has more supercar elegance, 4wd or AWD isnt the same. Drive a RWD, a 4wd and a AWD you'll see what I mean. RWD also gives the driver a much better feeling, there is nothing like the feeling when being pushed. For example no F1 car is AWD (or 4WD) they are only RWD its not that its faster its the way it drives and handles. If you know how to drive properly RWD is much better on turns and is more controllable then AWD (sounds stupid and wrong but any professional can show you that when leaving a turn in a RWD car there is more control). Also leaving out a 4WD or AWD system saves alot of weight. Remember that the you have to have 2 separte differentials and the transmisson is bigger. Ferrari, Koenigsegg, McLaren all are RWD and are considered the fastest cars. Lamborgini AWD is very good but doesnt beat Ferrari's RWD. Ferrari knows what there doing they win all the awards and races all the time.
