It's only a matter of hours before BMW drops the ball on its much anticipated 1 Series M Coupé, but for now, the Bavarian automaker has released a video showing the production version of the sports car completely undisguised for the very first time. The short story is that the 1 Series M Coupé is based off the 135i featuring a straight-six engine capable of 340-horsepower or more, a wider body, upgraded chassis and all the other usual tweaks you'd expect from a car wearing the M badge. For the full story, we'll have to wait until tomorrow.
