The German based automaker BMW is planning to offer a four-cylinder engine for the M3 and M4, eventually.
The announcement hasn’t been made in an official press release, but this will be the next obvious step for the future generation of the M3 and M4, as the two models are currently coming with a six-cylinder engine under their hoods, from a previous V8. According to the BMW M Head of Product Management, Carsten Pries, the design process will not start with a power output in mind but a four-cylinder engine for the future generations of the M3 and M4 is still a possibility.
According to the BMW official, adopting a four-cylinder engine instead of a six-cylinder one will help reduce the car’s weight and along probably with two turbochargers, the two models will become faster than the outgoing ones. As you probably already know, the current generation of the M3 and M4 are both taking their power form the same 3.0 liter TwinPower Turbo six-cylinder engine, which is developing a total output of 431 HP (317 kW) and a peak torque of 550 Nm (406 lb-ft), enough for a 0 to 100 km/h sprint made in just 4.1 seconds and an electronically limited top speed of 250 km/h (155 mph).
