The F97 X3 M is taking advantage of the inhospitable Northern Swedish weather to test its cold weather chops. It's dropped a bit of camo up front to reveal the production headlights. And we now know that the
F97 X3 M will debut an all-new S58 engine, which should also power the next generation M3 and M4.
The X3 M will be introduced in early 2019 and begin production as a MY2020 vehicle (U.S.). The new S58 engine will make 450-460 HP.
