1987 Porsche 962C GTi

The 1987 Porsche 962C GTi, an evolution of the highly successful Porsche 962 line, introduced refinements and technical innovations that made it one of the most advanced and competitive prototypes in Group C racing. Developed in collaboration with Richard Lloyd Racing, the 962C GTi featured a modified chassis that used lightweight honeycomb aluminum in place of the standard sheet aluminum. This innovation enhanced structural rigidity while reducing weight, allowing the 962C GTi to handle higher levels of downforce and aerodynamic loads more effectively than its predecessors. Its aerodynamic design also integrated smoother bodywork with enhanced Venturi tunnels, which improved airflow and stability at high speeds, crucial for long straights such as those at Le Mans. 

Under the hood, the 962C GTi was powered by a 3.0-liter twin-turbocharged flat-six engine, which was carefully fine-tuned for maximum output while maintaining reliability in endurance racing. The engine, mated to a five-speed gearbox, delivered potent acceleration and top speeds that consistently rivaled other competitors in Group C. Furthermore, the 962C GTi’s spool differential contributed to its stability on straights but required skilled handling in tighter turns due to a tendency toward understeer. For suspension, it featured dual unequal-length wishbones at the front and a unique rear suspension layout that kept critical components out of the aerodynamic underbody tunnels. The car’s braking system relied on robust steel disc brakes, ensuring reliability through lengthy, demanding races.
