Gone are the days of the high-revving V8, also in the new M-Boliden from Munich, which were shown on the NAIAS are giving their world premiere, downsizing is the order of the day. An in-line six-cylinder now provides a fire under the aluminum bonnets of the BMW M3 and BMW M4.

The three-liter unit, derived from the N55 engine, is fluffed up by two turbochargers. This means that the BMW M3 and M4 have 431 hp at 5,500 rpm. and a full 550 Nm of torque, which is already achieved at 1,850 rpm. concern, ready. 11 HP more power and 150 Nm more torque should comfort even the most hardened M fans over the loss of two cylinders. Despite immense power from the cellar, the six-cylinder does not shy away from high revs. Up to 7,600 rpm. It can be.

Shifting takes place as standard using a manual six-speed gearbox with an automated double-declutching function. For a surcharge, the six-cylinder can also be coupled with a seven-speed dual clutch transmission, which was borrowed from the M5 /M6 models. An active limited slip differential is always on board. When manually switched, the new M models should spurt from zero to 100 km /h in 4.3 seconds.

BMW M3 and M4 regulate 250 things

With the DKG, the spurt times should be even drop to 4.1 seconds. The DKG also has gadgets such as launch control and a burn-out mode.
