The E60 M5 was introduced in 2005, with a V10 engine intended to link the car with the BMW Sauber Formula One team. The E60 M5 was the world's first production sedan to feature a V10 petrol engine. As with some of its predecessors, the E60 variant of the M5 was both the quickest and fastest 4-door sedan in the world at the time of its release.
Other unique M5 features include a wider track, unique body panels, 7-speed SMG III sequential manual gearbox, also known as a single-clutch automated manual transmission, a color heads up display [HUD] featuring navigation, control messages, speed, rpm and gear selection information, automated seat side bolsters, heated/ventilated seats and power rear curtain. The larger, flared front guards on either side also featured cooling vents, reminiscent of the 1970s BMW CSL. The wheels were of a standard 19" diameter with quad exhaust pipes to the rear.
