Driving hard and fast in the rain heightens the senses, requires added concentration, and demands smooth shifting, steering, and throttle input. In the rain, the 2006 BMW M Coupe’s DSC/ABS systems helped keep the slithering sports car aimed toward the next apex rather than the Armco. Obviously, we cannot assess grip due to the wet track conditions, though the summer performance tires did a dandy job of battling the elements. Likewise, since we didn’t punish the brakes or suspension, it’s impossible to determine how this car might fare on a warm, sun-dazzled track. However, note that the standard brake drying system, which intermittently puts the pads in contact with the rotors to squeeze moisture out for maximum braking capability in foul weather, worked brilliantly. Finally, the M Coupe’s steering is a huge improvement over the electrically-assisted Z4, letting the driver place the car exactly where he wants it. This is a confidence-inspiring ride in unfavorable conditions – we just wish we could tell you what it’s like to drive in the dry.
