1981 BMW M1
Only 456 M1s were produced between 1978 and 1981.
The mid-mounted, fuel-injected, 277-horsepower, double-overhead-cam six-cylinder engine facilitated top speeds in excess of 262 km/h, thanks to the M1’s outstanding power-to-weight ratio. Such numbers should not be regarded as surprising, as early development of the M1 was in partnership with Lamborghini.
