Test Driver Ratings & Comments
Acceleration commentsTimes improved with pedal overlap and resulting slight wheelspin. Also noticed upshifts in Drive were occurring about 500 rpm shy of redline so best run was with manual shifting. Upshifts were still quick and smooth. Engine/exhaust sounds are isolated but present. All runs (but first, default run) were in Sport on rotary selector.
Braking commentsVery good. Strong brakes, medium-firm pedal, quick-cycle ABS and very consistent results that also showed virtually no signs of fading.
Handling commentsGood. Skid pad: With VSC off, the M37 felt very well balanced/tuned to deliver a neutral attitude; right on the cusp of kicking the tail out at will. Nice steering weight and tactile info. With VSC on, throttle bleeds off to drop speed slightly, and either ON/OFF, the clockwise direction (driver outboard) was noticeably slower. Slalom: VSC is truly off, but the chest-flattening seatbelt tensioners were a bit of a welcome surprise. Crisp initial turn-in lasts just a cone or two when the M37 begins to understeer. I could induce rotation with the throttle, but by that time, the tires had gone a little "greezy" and diminishing returns had set in. This car ran out of tire before it ran out of talent.
