We know that a stunning little BMW M2 is on the way and now we have some concrete proof that they are testing the quad exhausts that have become a hallmark of BMW M vehicles. The sensor on the roos if there to monitor vehicle speed and they do this when they are testing different sizes of tyre on the vehicle. You can clearly see the flared fenders, wider track and some M brakes but the front and rear bumpers are simply M Sport bumpers and these will change for the M2 production car. The car will be produced late in 2015 with the first deliveries taking place at the end of next year or early 2016. The N55 inline 6 turbo engine will likely be producing about 370 horses so this will be a proper M car.
