BMW uploaded a video on Youtube of their upcoming BMW 1 Series M Coupe. The new purist oriented M will be unveiled early next year, all clues point to a Detroit Auto Shoe debut.

While plenty of secrecy remain around the 1 Series M Coupe engine of choice, rumors have the engine as the same one as in the 135i’s – right down to the twin turbos. However, an engine remap and extra boost send power spiraling to around 350bhp. All that grunt in a small coupe bodyshell is contained by a limited slip diff and sticky 245/35 ZR19 and 265/35 ZR19 Michelin Pilot Sport rubber.

Engine is mated to a six-speed manual gearbox—no automatic or dual-clutch transmission will be offered, and according to first journalists to see the pre-production models, the manual shift suits the car very well.

Stay tuned for more official information in the upcoming days!
