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.
With their 3.8-liter turbo V6s, the all-black Buicks ruled the street in the 1980s. They were also the first and only American muscle cars powered by something other than a big V8.
