Thread: Say bye-bye to the BMW high-reving M engines

Well, it's official, BMW are dropping their high-reving V8 and V10 atmospheric engines on their next generation M cars. Audi removed the V8 from the B8 S4, replaced it with a turbo 6. Rumours have it that the S5 will also lose the V8 in favor of the v6 turbo. The 3.2L V6 has been dropped from the A6 in favor of the 3.0T for 2009.

The first V8 Twin Turbo M engine will make its debut on the upcoming 2010 X6 xDrive M, which will challenge the Porsche Cayenne GTS and the Mercedes-Benz ML63 AMG.

Set to appear next June, the X6 xDrive M will be the first model to run BMW M's new twin-turbocharged V8. This engine is also earmarked for the next-generation M5, due out in late 2010.

Based on the standard X6 xDrive 5.0i's 4.4-liter 90-degree V8, the new twin-turbo unit is said to match the current M5's naturally aspirated 5.0-liter V10 for power at 500 hp, while providing as much as 516 lb-ft of torque.

Mercedes-Benz's AMG is also planning turbocharge its 6.2-liter V8 when it introduces direct injection in 2010.

i think that MB's AMG division will go back to the 55's. It makes sence for bmw to turbo charge their M engines, especially since they have always been low on torque in comparison with the AMG engines.
