BMW reps will be hard pressed to deny the existence of a high-performance 1 Series thanks to some new spy photos (and video) that have been captured of the uncovered car lapping the Nürburgring.
What is obvious from the photos are some M3 design cues, some big wheels (reminiscent of the M3 Competition package wheels) and who could miss those massive flared fenders out back indicating some larger rubber is probably in order to deal with the added power. As for what kind of power this car might make, it's anyone's guess. The M3 V8 is most certainly not an option, so expect to see a powerplant similar to the one in the 335is, making 320-hp and 332 ft-lbs of torque (370 ft-lbs for a limited time). Other items rumored to be included are a limited slip differential and an optional 7-speed dual-clutch transmission.
It's not yet clear if BMW will name this car the 135is or perhaps the 1 Series M.
