40 years' turbo experience in motorsport and series production
At Porsche, innovations and developments that have proved themselves under extreme racing conditions always benefit production models, too.

Testing in motorsport in particular ensures the performance and resilience of new engines for production sports cars. In the development of charged six-cylinder flat engines Porsche can therefore look back on more than 40 years' experience. For example, turbocharging with a bypass valve was first used in 1972 in the 917/10 racing car before entering series production two years later in 1974 in the first 911 Turbo. In 1974 charge air cooling was also first introduced in the 917/10. In 1977 this technology then celebrated its premiere in the 911 Turbo 3.3. Further milestones in the development of turbo engines include sequential turbocharging with two consecutive chargers (for the first time in the super car 959), biturbo charging with two parallel chargers (for the first time in the 911 Turbo, type 993) and adjustable intake valves (for the first time in the 911 Turbo, type 996).
