BMW M GmbH has announced the end of production of the BMW M6 Coupé and the BMW M6 Convertible; production will now also cease for the unique V10 high-rev engine.
For two years in succession, 2005 and 2006, the 373 kW/507 hp ten-cylinder engine took overall victory in the Engine of the Year Award, and in the two years that followed achieved first place on each occasion in the category for engines with displacement above 4 liters.
The stand-out feature of this unique engine, developed exclusively for the BMW M5 and BMW M6 models, is power delivery that is both dynamic and smooth even at higher loads. Output is developed from a 5-liter displacement split between ten combustion chambers, with the two banks of cylinders cranked at 90 degrees to one another. The engine delivers maximum output at 7,750 rpm, with engine speed eventually peaking at 8,250 rpm, and it has maximum torque of 520 N&iddot;m (383 lb-ft).
In addition to the high-rev concept, a number of other technological details, such as electronically-controlled individual throttle valves, an ionic current control system and lateral force-controlled oil supply, were also directly derived from motor racing.
