Porsche 962 Research Hub
This is your center for all things Porsche 962. The ultimate reference center.
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 formula as the 956 had). 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, with some examples still proving competitive into the mid-1990s. Due to the sheer numbers of 962s, some teams took it upon themselves to adapt the car to better suit their needs or to remain competitive. Beyond minor modification, some private teams reengineered the entire car.
