Porsche 962
The Ultimate Guide
When the Porsche 956 was developed in late 1981, the intention of Porsche was to run the car in both the World Sportscar Championship and the North American IMSA GTP Championship. However IMSA GTP regulations differed from Group C and subsequently the 956 was banned in the US series on safety grounds as the driver's feet were ahead of the front axle center line. The Porsche 962 (also known as the 962C in its Group C form) was built by Porsche as a replacement for the 956 and designed mainly to comply with these IMSA's GTP regulations (it would later compete in the European Group C). The 962 was introduced at the end of 1984, from which it quickly became successful through private owners while having a remarkably long-lived career.

The Porsche 962: The Endurance Racing Legend That Defined an Era
The Porsche 962 is one of the most dominant and celebrated race cars in motorsport history. Introduced in 1984 as the successor to the groundbreaking Porsche 956, the 962 continued Porsche's tradition of excellence in endurance racing. Built to comply with the FIA Group C regulations in Europe and IMSA GTP rules in North America, the 962 proved to be a versatile and reliable machine that achieved unparalleled success on both sides of the Atlantic. Its blend of speed, reliability, and cutting-edge technology made it a favorite among factory and privateer teams, cementing its place as one of the greatest race cars of all time.
Origins and Development
The Porsche 962 was developed as an evolution of the 956 to meet the stricter safety regulations set by IMSA (International Motor Sports Association). The primary change was the extension of the wheelbase to move the pedal box behind the front axle, improving driver safety. This modification also made the 962 eligible for competition in IMSA’s GTP category, where the 956 did not qualify.
The 962 retained the aluminum monocoque chassis and ground-effect aerodynamics that made the 956 so successful. Powering the 962 was a 2.65-liter twin-turbocharged flat-six engine producing around 620 horsepower in its Group C configuration. The IMSA version initially used a 3.2-liter single-turbocharged flat-six engine to comply with IMSA’s rules on fuel consumption and boost limits.
Throughout its production run, the 962 underwent continuous development. Teams experimented with different bodywork designs, suspension setups, and engine configurations, making the 962 a platform for innovation and adaptation.
Racing Success
The Porsche 962 quickly established itself as a force to be reckoned with in endurance racing. Its debut victory came at the 1984 24 Hours of Daytona, driven by Mario Andretti, Michael Andretti, and John Paul Jr. This win set the stage for an incredible run of dominance in both the IMSA GTP and Group C championships.
In IMSA competition, the 962 was virtually unbeatable throughout the mid-to-late 1980s. It won the IMSA GTP Championship in 1985, 1986, 1987, and 1988, with drivers like Al Holbert, Derek Bell, and Chip Robinson behind the wheel. The 962 secured multiple victories at prestigious races such as the 12 Hours of Sebring, the 24 Hours of Daytona, and numerous other endurance events.
In Europe, the Porsche 962 continued the success of the 956 in the World Sportscar Championship. The 962 won the 24 Hours of Le Mans in 1986 and 1987, driven by Derek Bell, Hans-Joachim Stuck, and Al Holbert. These victories solidified Porsche’s reputation for engineering race cars that were not only fast but also incredibly durable and reliable.
Privateer teams played a crucial role in the 962’s success. Teams like Joest Racing, Kremer Racing, and Brun Motorsport fielded 962s with great success, often developing their own modifications to improve performance and aerodynamics. The 962 remained competitive well into the early 1990s, with some teams continuing to race the car until 1994.
Design and Innovations
The Porsche 962 was a marvel of engineering, combining proven concepts from the 956 with new safety and performance improvements. The aluminum monocoque chassis provided a rigid and safe structure, while the ground-effect aerodynamics generated massive amounts of downforce, allowing the 962 to corner at incredible speeds.
One of the key innovations of the 962 was its adaptability. The car could be configured for different types of races and regulations, with teams modifying bodywork, suspension, and engines to suit specific tracks and conditions. The air-cooled, twin-turbocharged flat-six engine was both powerful and reliable, capable of delivering sustained performance over long distances.
Many 962s featured custom bodywork developed by privateer teams, including advanced aerodynamic elements such as extended tails, larger wings, and revised front ends. These modifications helped keep the 962 competitive against newer designs from rivals like Jaguar, Nissan, and Toyota.
Legacy of the Porsche 962
The Porsche 962’s impact on motorsport is immeasurable. With over 180 victories to its name, the 962 is one of the most successful race cars ever built. Its dominance in both IMSA and Group C racing during the 1980s and early 1990s set a standard for endurance racing that few cars have matched.
The 962’s success also influenced the design of future race cars, with lessons learned from its aerodynamics, chassis construction, and turbocharged engine technology finding their way into subsequent Porsche models and other manufacturers’ race cars. The car’s versatility, durability, and adaptability made it a favorite among drivers and teams, and its legacy lives on in the memories of its incredible performances on the track.
Today, the Porsche 962 is a coveted collector’s car, celebrated for its engineering brilliance, racing pedigree, and timeless design. It remains a symbol of Porsche’s relentless pursuit of motorsport excellence, a reminder of an era when the German marque ruled the world of endurance racing.
