More information.

Today's 3.0-litre BMW in-line six-cylinder engines feature innovative technology, intelligent lightweight construction and state-of-the-art combustion management. The petrol models now achieve levels of fuel efficiency previously attained only by diesel engines, thanks to innovations such as direct injection (High Precision Injection) with lean burn, Valvetronic, double-Vanos and ancillary units that operate on demand. In addition, the use of lightweight components such as an aluminium-magnesium alloy crankshaft, a magnesium cylinder head cover and composite camshafts gives the engine a low weight that belies its high power.

The straight six-cylinder petrol engine line-up is topped by a high-performance Twin Turbo variant. It's an emphatic demonstration of the BMW six's potential. BMW in-line six-cylinder engines are available in different variants.
