BMW M3 Saloon and BMW M4 Coupé. Facts overview.

New 3.0-litre inline six-cylinder petrol engine with M TwinPower Turbo technology and

425 hp – high-performance turbo engine with maximum engine speed of 7,600 rpm-1.

Maximum torque of 406 lb-ft available from just 1850 rpm-1 – turbocharging ensures noticeably

more torque at lower engine speeds than the V8 predecessor.

7-gear DCT transmission with integrated Launch Control.

Six-speed manual transmission with throttle blipping.

Curb weight of just 3,530 lbs (M4 Coupe 6MT) thanks to intelligent lightweight construction to the

smallest detail: standard features include CFRP roof, CFRP driveshaft, aluminum hood with

powerdome and front fenders.

Exhaust system with innovative flap concept for increased efficiency and a striking M sound.

Newly developed electro-mechanical M Servotronic steering with three settings for very high

precision and authentic feedback from the road.

Unique equipment: Active M differential, LED light, Head-Up Display (optional), M Carbon

Ceramic Brakes (optional).
