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 ratingVery Good
Braking commentsStrong brakes, medium-firm pedal, quick-cycle ABS and very consistent results that also showed virtually no signs of fading.
Handling ratingGood
Handling commentsSkidpad: With stability control off, the M37 felt very well balanced, delivering a neutral cornering attitude and right on the cusp of letting you kick the tail out at will. Nice steering weight and tactile info. With stability control on, throttle bleeds off to drop speed slightly, and the clockwise direction (driver outboard) on the skid pad was noticeably slower whether the stability control was on or off. Slalom: Stability control can be completely disengaged, although the seatbelt still snugs down against your chest. Crisp initial turn-in lasts just a cone or two when the M37 begins to understeer. Could induce rotation with the throttle, but by that time, the tires had gone a little greasy in grip and diminishing returns had set in. This car ran out of tire before it ran out of talent.
