12. BMW M1
Even though the M1 was not a commercial success since they only sold 453 copies, this limited production sports car was tremendously important for BMW’s future. It is also one of the best-known wedge-shaped supercars they ever made (via Car And Driver).
The heart of this sports car was BMW’s famous M88 six-cylinder engine with 3.5-liters of displacement. It also had advanced fuel injection and 273 HP, which was a high number for the day’s standards. But today, even the BMW 320 with a diesel engine can match M1’s performance. They positioned the engine longitudinally just behind the driver and the passenger.
