Same restless BMW insider Scott26 reports on Germancarforum that this weekend, November 20th and November 21st, BMW will showcase the upcoming 1 Series M Coupe at the BMW Welt in Munich.

Official unveiled on the highly awaited 1M will take place in the second half of December with world public premiere at the Detroit Auto Show.

Along with the 1 Series Coupe and Convertible, the new 1M receives the LED treatment. Despite its looks closer to the 135i Coupe model, the new 1 Series M Coupe is almost an entirely different car. Almost every suspension part is different. The springs are stiffer and the dampers have less travel, the bushings of the trailing arms are changed from rubber to joint balls and some rubber ones are stiffer. The suspension cannot be adjusted – also to keep the cost down. The front axle carrier is the same as in the 135i, but in the rear the one of the M3 is used.

The body is lowered by 10 mm (0.4 in) and the track is approximately 30 mm wider up front and between 30 to 40 mm wider at the rear. The brakes are completely different from the 135i Coupe with M Compound brakes.

BMW 1M is powered by an engine based on N54 twin-turbo delivering 340 horsepower. Engine is matted to a six-speed manual.

Pricing is expected to place the BMW 1M between the 335i and M3 models.
