Steve McQueen had entered this Porsche as “research” for his upcoming lm, Le Mans. The little 3-liter ran awlessly and took the lead in the last hour, only to be overtaken by Mario’s larger, 5-liter 512. McQueen was driving with a broken ankle from a motorcycle accident. He still did pretty well against much more experienced professional drivers, most of whom gave him a lot of credit for his skill.
