In a little more than a week, BMW will finally unveil the successor of the 1M – The F87 M2. The compact sportscar is one of the most expected models of the year and one that has the BMW community on their toes. The F87 M2 has been teasing over and over again this year with a stubborn camouflage paint job that never seems to unveil more than it should. Other teases include high-speed runs at the Nurburgring where the M2 has been now almost every week.

Just like this last teaser which shows an M2 prototype doing some hot runs at the famous race track.

Earlier this year, we exclusively announced that the new BMW M2 will use the N55 engine which has been revised to include some parts from the S55 powerplant found in the new M3/M4.

BMW unveiled this week the X4 M40i, the M Performance Automobile also powered by a revised N55 unit. Looking at the specs, the engine of the BMW X4 M40i is a close relative of the engine for the BMW M2 F87, with the M2 Coupe getting an even sharper power stage with a power rating of 370 hp and improved response.

The basic N55 engine is used in both vehicles with a 3.0 liters of displacement and a twin scroll turbocharger, however, some components from the S55 are included for more stability and to allow an increase of boost pressure and injection quantity. An optimized air intake and an optimized exhaust system are also included.

The increase in performance compared to the normally offered 306hp, 320hp or 326 hp base engine is possible because BMW uses some parts from the 431 hp S55 engine. The forged steel crankshaft, the crankshaft bearings and the special pistons and high-power spark plugs will allow an increase in the peak power combined with optimum durability in most sports usage.

Thanks to further improved cooling with a separate oil cooler, the engine of the BMW M2 should also easily handles even the most demanding race tracks, like the Nürburgring Nordschleife.
