By Janos Wimpffen. Sports-car racing enjoyed one of its strongest decades during the Group C era of the 1980s and early 1990s. This period brought new techniques in chassis construction, refined aerodynamics and improved engine management systems. It also boasted a strong mix of competitors that included major manufacturers such as Porsche, Mercedes, Jaguar and Peugeot, as well as several long-running private teams. Together they raced such powerful and exotic cars as the Porsche 956 and 962, the Sauber-Mercedes, the Jaguar XJR series, and the Peugeot 905. This is the fourth in the Wimpffen series of Sports Car Racing volumes and covers the original race history of cars that have now become competitors again in a fabulous historic series. Hardback, 420 Pages, Size: 280 x 330mm. Book is new and unread.
