BMW M5 - E28 (1985 to 1988)

The first BMW M5 was introduced in 1985. Based on the E28 5 Series, the M5 featured various mechanical improvements to the drivetrain, as well as being fitted with a BMW M1 derived engine. When the M5 was launched, it was the world's fastest production sedan. While all E28 M5 cars were fitted with a 3.5L straight six, North American cars were fitted with catalytic converters that reduced power to 256hp from the European model's 282hp. Built until 1988, the E28 M5 was replaced by the E34 M5 for 1989. At the end of production only 2,241 examples of the original M5 had been produced.
