The BMW M5 is a high performance version of the BMW 5-Series executive car built by the Motorsport division of BMW. First introduced at the Amsterdam Motor Show in 1984, the first incarnation of the M5 was hand-built utilizing the 535i chassis and a modified BMW M1 engine, being the fastest production sedan in the world at the time of its introduction. Subsequent iterations of the M5 have been built from each generation of the 5-Series platform, including the E34, E39, E60/E61, and most recently, F10, with the first orders delivered in late 2011.
