AWD utilizes the power of all four wheels to move the car. Front Wheel Drive pulls the car foward, and RWD pushes it. I would think pulling something might have better speed, better stability....and less drifting. So, FWD would probably be better for torque....I think......
RWD pushes the car, and that will cause tighter turns, well at least for me. It can also be useful for drifting........but, that's just me.
AWD has more traction, a LITTLE less speed, but the loss in speed can easily be remedied with the metal bearings. Correct me if I'm wrong (Don't take this too oppurtunisticly RedRSX

) but I would think AWD may cause a tighter turning radius. It WOULD put out more torque, and have more of an advantage than RWD or FWD in some cases. It might lessen drifting, but it also may help, depending on your style and skills or driving. *Suddenly comes out of trance*
Woah, what did I just say???............
