The BMW M5 is back!

BMW's M division has gone back to the drawing board with the M5, giving the fifth generation of the iconic four-door a twin-turbocharged 4.4-liter V8 engine—the first time Munich's class-defining performance sedan has gone without a naturally aspirated powerplant since its introduction in 1984. Further changes see it adopt a dual-clutch gearbox as part of a complete driveline rethink that resigns the old model's sequential manual transmission to the history books. Revealed here officially for the first time, the new M5 is planned to make its world debut in concept-car guise at the Shanghai motor show later this month.

Carlsson C25 super coupé (2010) first official pictures

Mercedes tuner Carlsson will whisk the covers off this slinky new sports coupe at the 2010 Geneva motor show.
