The twin-turbocharged manual transmission, all-aluminum, 3.0-liter inline-6 engine is characterized by instantaneous response to the accelerator pedal, fantastic sounds, and a free-revving spirit. The combination of twin low-mass turbochargers and Bimmer’s High Precision direct injection offers an output a naturally-aspirated engine would only be able to provide through more cylinders and larger displacement. The turbocharger system developed for the engine of the new 1 Series M Coupe maintains a high output throughout the entire engine speed range. Maximum output of 335 hp (250 kW) is delivered at 5,900 rpm. Nominal peak torque is 332 lb-ft (450 Nm) from 1,500 rpm to 4,500 rpm. Redline is 7,000 rpm. The enhanced engine management system of the 1 Series M Coupe includes an electronically-controlled overboost function to briefly increase torque under full load by another 37 lb-ft (50 Nm).
