Moffat's last Bathurst 1000 victory. Group C carried over into the 1980s. Holden and Ford were the only manufacturers to win under these regulations, despite facing increased imported competition, notably from the Mazda RX-7 that was campaigned effectively by Moffat and Kevin Bartlett's 350 V8 powered Chevrolet Camaro. The turbo powered Nissan Bluebird piloted by George Fury also threatened the V8 'Big Bangers' and signalled a sign of things to come during the Group A era. Peter Brock cemented his reputation as the driver to beat during this period, including achieving two Bathurst hat-tricks with the Marlboro-sponsored HDT. In 1978 and 1979 he and Jim Richards drove an A9X Torana to victory, while in 1980 the pair won in a VC Commodore. His second hat trick consisted of victories in 1982, 1983 and 1984, this time partnering with Larry Perkins in a VH Commodore for the first two years and in a VK Commodore in the third. In 1983, John Harvey also shared the win with Brock and Perkins. Dick Johnson was the only winner for Ford during the 1980s under Group C, with a victory in 1981 whilst at the wheel of the XD Falcon. It was a famous win, coming twelve months after writing his car off in an incident with a rock in 1980. It also followed a large public fundraising campaign to provide him with the finances to build a new car, which eventually raised AU$144,000, half of which came from Ford Australia itself. Group C was replaced by the International Group A Touring car rules in 1985, with selected cars preparing for this change and competing in a separate "Group A" class in 1984. Group A Era From 1985 to 1992, the Bathurst 1000 was run to international Group A regulations. Imported turbocharged cars, initially Ford Sierra RS Cosworths and then Nissan Skyline GT-Rs, achieved dominance during this period while Holden Commodores managed to claim three hard-fought wins. The JPS Team BMW run 635 CSis and M3s were also highly competitive during this era. Group A enabled Australian teams to develop cars that could be raced overseas. Locally built cars were driven in Europe by Allan Grice, Peter Brock, John Harvey, Allan Moffat, Dick Johnson and John Bowe. Tom Walkinshaw also briefly campaigned VL Commodores in Europe. Holden based race teams continued development of the 308 cubic inch V8 powered Commodore. The HDT and later
