Incredibly tiny and powered by a Ferrari V6, the Stratos was a rally car disguised as an alien starship. And it was World Rally Champion in 1974, 1975 and 1976.
Porsche built 25 917s for homologation in 1969. It won Le Mans in 1970 and 1971, only losing when the rules changed. The 917 still holds the Le Mans fastest lap record.
