The twin-turbocharged, all-aluminum, 3.0-liter inline-6 engine is characterized by lagless engine response to the accelerator pedal, fantastic sounds, and a free-revving spirit. The combination of twin low-mass turbochargers and BMW’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). This temporary torque peak of 369 lb-ft gives the car a substantial increase in acceleration. The 1 Series M Coupe will complete the sprint from a standstill to 60 mph in just 4.7 seconds (0-100 kmh in 4.9 seconds). The standing quarter-mile mark comes up in 13.2 seconds. Top speed is limited electronically to 155 mph (250 kmh).

The exhaust system of the 1 Series M Coupe has been tuned by M specifically for this new model. Acoustic engineering gives the car a unique personality in all phases of operation. The M exhaust system is easily recognized by the usual Quad Exhaust on the other M-Powered cars.

The new 1 Series M Coupe also features the steering wheel-mounted M Drive button that made its first appearance in the 2005 M5. In the 1 Series M Coupe, the M Button activates a razor-sharp throttle response program for the sportiest driving. This means that the performance characteristics of the engine can be varied according to the driver’s wishes.

As an alternative to normal operating status, the driver can activate M Dynamic Mode (MDM) by means of pushing the MDM Button between the front air vents, raising the intervention thresholds of the DSC system. MDM enables slight amounts of dynamic oversteer under specific circumstances to enable optimum vehicle yaw for maximum performance. Demonstrations at the BMW Performance Center in Spartanburg, S.C. have proven MDM mode to enable the fastest-possible lapping performance while still providing the assurance and protection of Dynamic Stability Control. MDM also facilitates starting off in snow or loose surfaces by means of carefully controlled amounts of wheelspin. And most importantly the DSC may be fully disabled via a long-press of the MDM button (ABS remains active).

A close ratio 6-speed manual transmission is used for power transmission to the rear wheels in the BMW 1 Series M Coupe. It was specially designed to interact with high-torque engines and has been fitted for this purpose with a dry sump cooling system. An upgraded flywheel for high-torque applications is installed between the engine and transmission. The transmission is operated using a very short M gearshift lever. Final drive ratio is 3.15: 1.
