Porsche 917 K
Porsche's 917K ('K' for Kurzheck or short-tail) represents the pinnacle of the original prototype racing era. Developed to dominate sports car racing, the 4.9-liter flat-twelve produced 580 horsepower and propelled the lightweight chassis to speeds exceeding 220 mph. After initial aerodynamic problems, the short-tail body provided crucial stability, enabling Porsche to capture its first Le Mans victory in 1970. The distinctive Gulf livery and starring role in the film 'Le Mans' cemented the 917's legendary status as one of history's greatest racing machines.
