1. Porsche 959

Notable Features: Was called world's fastest street-legal production car in 1986; was one of the first supercars to feature AWD

Complex Says: To compete in FIA-sanctioned Group B rally events, rules of the time stated that a minimum of 200 road-going versions of competing cars must be sold. The 959 was released to meet that homologation requirement. As with many other rally homologations, it was one of the most interesting, technologically advanced cars on the road for its time.
