Any doubt that BMW's M Division was in fact tuning the BMW 1 Series Coupe can now be laid to rest, with this latest batch of spy photos proving the prototype certainly belongs in the M stable.

In case the massively flared wheel arches, huge brake kit and enormous wheels weren't enough to convince you, the trademark M Division quad-exhaust pipes can now been seen clearly amongst the camouflage at the rear.

As we take a closer look underneath the car we can also see the limited slip differential sitting between the enormously wide rubber - the cooling fins a dead giveaway.

No matter what name the eventual production model goes by - M1, 1 Series M, tii - this latest addition to the M line-up is sure to be one potent little pocket rocket, and just in time to play with the upcoming Audi RS3 super hatch.
