9. BMW M1
Although M1 was not a commercial success and it sold in only 453 copies, this limited production sports car was tremendously important for the brand and BMW`s future. It is also one of the best known wedge-shaped supercars ever made.
The heart of this sports car was BMW`s famous M88 six-cylinder engine with 3.5-liters of displacement, advanced fuel injection and 273 HP which was a pretty high number for the standards of the day.
