Ahead of the FISA standard introduced in 1987, Porsche further developed the 956 into the 962. The Porsche 962 was essentially a type 956 with new pedals, a front axle positioned 12 cm further forward and a steel roll cage. The six-cylinder turbo engine was now water-cooled and generated 700 bhp. A technical innovation came in the form of the semi-automatic Porsche Doppelkupplung (PDK) which was optionally available for the 962 C. The championship had meanwhile also undergone a change: The race series was given a new name and was now known as the World Sportscar Championship. With the 962 C, Porsche continued its series of victories not only in Le Mans, but also in the World Sportscar Championship and the American IMSA, until a new handicap rule finally ended its run in 1990. From 1991, racing cars powered by naturally aspirated engines contended for victory. After 41 wins in the World Sportscar Championship and six triumphs in Le Mans, the Porsche 952/962 C was finally consigned to the museum as the most successful racecar of all time.
