Built to help win World War II, the original military Jeep MB would develop into the civilian CJ and, eventually, today's Wrangler. It is the 4x4 that made the idea of four-wheel drive acceptable.
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.
