Last weekend, the camouflaged BMW 1 Series M Coupe was showcased at the BMW Welt. BMW enthusiasts are excited about the great reveal that will be happening this December at the Detroit Auto Show. Until then, all we know about the vehicle is that it receives the LED treatment, it has an entirely different suspension than the 135i Coupe, the body is lowered by 10 mm (0.4 in), the track is 30 mm wider up front and between 30 to 40 mm wider at the rear, and it also has an engine based on N54 twin-turbo matted to a six-speed manual producing 340 horsepower.
