What happened to the SLK, Daesun?

The acceleration of the car in drag racing will depend on weight distribution, gearing, suspension, aerodynamics--if AWD were hands down superior, professional drag racing cars would be AWD. Ever seen one?

AWD probably provides better handling for the majority of us. I have been told that a rally car driver can usually get better handling from RWD. Supposedly FWD is the worst from a handling standpoint. But again there is a great deal that can be done with suspension, steering, and such to improve handling. My guess is you would need to actually build the car and test to find out which is superior in any given case (or perhaps perform computer modeling).
