After Jaguar’s World Sportscar title and Le Mans successes in 1988, the imposing silver Mercedes dominated the next two seasons, but the presence of Jaguar, Nissan, Mazda, Toyota and the evergreen privateer Porsche squads demonstrated the category’s international appeal. And that’s before taking into account the popular American equivalent, IMSA GTP, which Jaguar, Nissan and Toyota also contested.
Group C was finally killed off by the controversial switch to the 3.5-litre regulations – crucially not supported by Porsche – that started in 1990 and became predominant the following year. The change, which many observers suggested was a move by Bernie Ecclestone to encourage more manufacturers into Formula 1, led to dwindling grids. But even then, the final cars of the era – Jaguar’s XJR-14 and the Peugeot 905 – were among the most spectacular and rapid cars in sportscar history, challenging F1 lap times on occasion before the World Sportscar Championship died at the end of 1992.
Goodwood favourite, and multiple sportscar winner with Porsche and Mercedes, Mass agrees Group C was one of the high watermarks for endurance competition.
