The M5 model was introduced in 2005 and is powered by the BMW S85 V10 engine. It was sold in the sedan and wagon body styles, with most cars using the 7-speed SMG III transmission. It was the first and only M5 model to be sold with a V10 engine. The BMW M5 has found favour on UK roads since 1985. And during its 28-year tenure M5 engines have grown and been blown; such is today's downsized and turbocharged nature. This E60 M5, however, marks the point at which the mighty M was at its most monstrous. For this M5 features the first and likely last V10 engine in its lifetime. Bold numbers like these are great on paper, but downright inspiring when put into practice. The linearity at which that massive power is transferred to the rears has something to do with this awesome sensation.
