Porsche did not invent turbocharging. It didn’t even make the first production car with a rear-mounted air-cooled turbocharged flat-six; that honor goes to the Chevrolet Corvair. But while many of the early cars that used turbocharges had them as a substitute for a bigger engine (something that is currently happening again), the Type 930 911 was given a turbocharger in order to turn what was already a very fast and capable car into something even faster. It wasn’t a replacement for displacement, it was in addition to displacement. The 930 took turbocharging to a new level of performance for road cars, one that would go unmatched for nearly a decade.
