In this kind of construction, water coat encompassing the cylinders is closed at the very top, which endows the crankcase with an exceedingly high amount of stiffness.
BMW M3 and M4 engine unit components
The drive unit powering the new BMW X4 M40i is situated after the three-litre, in-line six-cylinder engine in the BMW X4 xDrive35i. To be able to fulfil the exacting strong demands positioned after BMW M Performance vehicles in every respect, our development engineers have optimised the drive product by using a forged material crankshaft in addition to components from the high-performance engine unit suited to the BMW M3 and BMW M4, that have been created in 2014. This is one way, among other activities, pistons with an designed top wedding ring, crankshaft bearings and high vitality spark plugs found their way from the six-cylinder inline engine unit with M TwinPower Turbo technology to the new BMW X4 M40i.
