Ferrari was foundering in the '70s. Its road cars were flaccid and boring. Then came the midengine, V8-powered 308 and the company had a hot seller. It saved Ferrari.
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.
