While the 904 GTS is most commonly seen with a four-cylinder engine, Porsche also fielded six and eight cylinder engined examples. Based on the engine developed for Formula 1, the flat eight used in the 904/8 displaced just under two litres and produced a hefty 240 bhp. Only two of the 904 Coupes were fitted with this engine, so unlike the four-cylinder engined cars, they 904/8s were never homologated and were forced to run in the prototype class. They were nevertheless quite successful with class wins in the Targa Florio and twice at the Nurburgring. Our 17-shot gallery includes both examples built. One of these is on display in the Porsche Museum, while the other is in private hands and has been reunited with the very rare eight-cylinder engine.
Long after Porsche had ceased developing the 962, privateers continued to extend the Group C machine's lifespan with modifications. This was a win-win situation for Porsche as the German manufacturer still supplied the running gear for these cars that remained competitive. Among the first of these was Richard Lloyd Racing, who commissioned Nigel Stroud to design a honeycomb aluminium monocoque to replace the sheet aluminium tubs originally used for the 962C. In doing so, they created the 962C GTi of which five chassis were built. Four were built to Group C specifications, while the fifth was sold to Dyson Racing and campaigned in the IMSA GTP series. The featured example was the last of these and did not debut until 1992 when it was shared by father and son Derek and Justin Bell in their first ever joint Le Mans effort.
