The next BMW M5 is due to arrive sometime in 2011 or 2012 and as the release date draws near, more details about BMW's newest 'Bahn-burner have begun to surface.

Two reports indicate that BMW may continue to use a V10 powerplant in the next M5, although there's still some evidence that the twin-turbocharged 4.4-liter V8 currently fitted to the X5M and X6M could be tweaked and fitted in its place. However, if BMW decides to stick with the bent-ten, a thoroughly revised version based off the 'utes' V8 would be employed, packing a duo of turbos to boost output up and over the 600 hp mark, and giving the Audi RS6 a run for its money.

But it won't be all about power. BMW is also expected to use an F1-style KERS system to increase performance and fuel economy, along with an engine start-stop setup and an eight-speed dual-clutch gearbox. If the rumors are to be believed, expect the next M5 to make its debut sometime in 2011, with sales beginning in early 2012.
