BMW M1000RR Electric-Supercharged Engine. A miracle of German Engineering. The engine implements MGU-K which is derived from their Formula-1 cars. But in place of MGU-H, it only has a generator unit which draws power from the turbine, and the turbine runs by the exhaust gas. The MGU-K does two things. First, it provides additional power to the engine. Second, it runs a centrifugal-supercharger which will increase power output of the engine. It's only for track use.
Max Power = 420HP @15,000 RPM
Max Torque = 180Nm @13,000 RPM
Bore = 81mm
Stroke = 48.4mm
