Source to a diesel BMW continues to be the charged three liter – straight-six engine. To make performance at the start for M, whose on-loading facilities was upgraded however. So the new engine works with three wheel loaders – two small high pressure loaders with variable geometry and larger low pressure system. A charge air cooler directly before the combustion chambers and two behind the low pressure systems provide for performance-enhancing air temperatures. In the niedertourigen area just above the idle speed, one of the two small loader becomes active first. The large loader to turns from approximately 1,500/min. The third loader in action occurs from approximately 2,700/min. Under full pressure of the cylinder developed HP. then from 4,000/min whopping 381 The maximum torque of 740 nm is located at from as little as 2,000/min.

Diesel and all-wheel it will not stay for the so-called optional performance, said BMW M head Friedrich Nitschke. BMW series, in which there is no designated M model, conceivable a particularly strong gasoline engine with an M before the type shortcut.
