the Group C Years: Fuel Limits, Prototype Monsters, and Golden Age of Endurance Racing

In the 1980s and early 1990s, endurance racing entered one of its most spectacular and unforgettable eras. A rulebook built around fuel limits was meant to encourage efficiency, but it produced something far more dramatic: closed-cockpit prototype monsters capable of astonishing speed, unforgettable sound, and twenty-four-hour punishment. The Group C Years: Fuel Limits, Prototype Monsters, and the Golden Age of Endurance Racing tells the story of the machines, teams, drivers, circuits, and regulations that defined this golden age. From the Porsche 956 and 962 dynasty to Lancia's brave Ferrari-powered challenge, from Jaguar's V12 return to Le Mans glory to Sauber-Mercedes' silver domination, from Nissan and Toyota's relentless Japanese campaigns to Mazda's rotary miracle in 1991 and Peugeot's final 905 triumphs, this book follows the full arc of Group C racing with a fact-based, narrative approach. It is a story of speed and restraint, factory power and privateer courage, engineering genius and regulatory risk. At Le Mans, Spa, Silverstone, Monza, Fuji, Suzuka, Daytona, Sebring, and the Nürburgring, these cars proved that endurance racing was never only about being fastest for one lap. It was about lasting through heat, darkness, traffic, fuel strategy, mechanical strain, and the pressure of the clock. For motorsport fans, Le Mans followers, and readers who love the engineering drama of racing history, The Group C Years captures the era when fuel limits created some of the wildest, fastest, and most beautiful racing cars ever built.
