BMW says that all-wheel-drive M cars are coming soon. That may be totally unnecessary, because this rear-drive M4 seems to put the power down just fine in a snow-pulling match against at four-wheel-drive Tacoma.
While we know you should take YouTube comments with grain of salt, the owner of the BMW does say he paid for the car in cash, and it is not some lease to hoon and then give back. If that is true it's nice to see someone having some fun with all that ///M goodness.
