The 1971 Porsche 917KH "Short Tail" Coupe was a legendary endurance racing machine, renowned for its distinctive compact rear design that improved handling and aerodynamics. The KH stood for “Kurzheck,” German for “short tail,” marking an evolution from the original long-tail 917. In 1971, the 917KH helped Porsche secure multiple victories in the World Sportscar Championship, including wins at the 24 Hours of Daytona and the 1000 km Nürburgring. Its powerful flat-12 engine and innovative engineering made it one of the most dominant and feared race cars of its era, laying the groundwork for Porsche’s continued success in endurance racing throughout the 1970s.
