With less than two weeks before its official unveil, a BMW M2 was spotted wearing the production-ready M mirrors. The test mule continues to sport the black and white tape which masks the latest design details. The prototype runs with the production-ready body kit and the black wheels which we know will be available at market launch.
The launch color palette will be limited: Long Beach Blue, Alpine White, Mineral Grey and Black Sapphire. New colors are likely to be offered in the future as a replacement to the first ones.
BMW unveiled yesterday 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 torque and power diagram shows the 360-hp N55 variant for the BMW X4 M40i with a rated output between 5,800 and 6,000 rpm/min. We currently estimate that the 365-370 hp version of the N55 will not provide its rated output in such a wide area, as well as can be expected with a little more torque.
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.
The wait is almost over and soon we’ll be able to see and feel what the M wizards been working on for the last two years.
