Grassroots Motorsports magazine's latest issue (11/02) did a little test on different drivetrains. Representing their respective drivetrain layout were: the WRX (AWD); the RSX-S (FWD); and the BMW 330i. They were all shod with 205/55YR16 BFG KDW tires and run through a ~40 sec track at Michelin Tires' proving ground.
The results were contrary to the conventional wisdom that RWD cars handle best: (average times)
WRX times: 40.59 wet, 41.988 dry
RSX-S times: 41.58 wet, 42.284 dry
330i times: 42.02 wet, 42.44 dry (DSC off)
42.218 wet, 43.982 dry (DSC on).
The results from both the wet and dry testing reveal the Subaru Impreza WRX as the clear winner among these three cars. Its times were considerably quicker than the other two, while the car was easier to drive at the limit to boot. p. 38
