does BMW just pull these numbers out of a hat?
first of all, the weight difference is not that much at all - max 250 lbs. the f20/21 is heavier than everybody thinks.
second of all, the M135 will be available with xdrive and that will launch 0-60 in about 4.6s, gear ratios are the same. It's just a traction issue to launch that gives xdrive the advantage. At speed an RWD M135 will blow by a 335xi.
