For those of you technical aficionados out there, here are the specifications for the new 1M. It shares the track of the M3, front and rear to the millimeter according to M Brand Manager NA, Matt Russell. Of note is the four inch shorter wheelbase than the 1M sports over the M3.

And for those of you that missed our comprehensive test drive of the 1M, here are some of our thoughts from the track:

“The 1M on the track is addictive. It’s a combination of great sounds, great chassis, and a thoroughly well matched powerplant to the car. It’s shorter wheelbase makes it just that much more nimble than larger cars and all of that torque, available almost off idle this will make the 1M a killer on any track with a surfeit of slow speed corners. This thing is nasty quick, it just digs hard out of the corners. Go wide open throttle and you’ll get the additional torque from the overboost function for about five seconds, enough to propel you headlong into the next corner.

But it all comes back to how easy this car is to drive. It’s forgiving, sure footed, exceptionally quick, with a brilliant set of brakes and great steering and steering feel. If you ever intend to do track days (and especially if you’re a track day junkie) this car has to be at the top of the short list.”
