King of Group B: Audi Ur-Quattro

The Quattro’s debut in 1980 took the world of rallying by storm. Making use of recently changed rules which allowed all wheel drive in competition the cars were nigh-on unbeatable. Michėle Mouton became the first female driver to win a world rally in 1981 doing so behind the wheel of a Quattro, and also won the 1985 Pikes Peak International Hill Climb in one.

The Quattro’s final incarnation, the S1, was produced to compete in the FIA’s infamous Group B. The rules allowed almost anything manufacturers could dream up in terms of technology and boost pressure. As a result the Quattro S1 E2 sported carbon-kevlar bodywork and its 2.1 litre engine was rated at 470 bhp. In reality it had well over 500 thanks to a turbo system that recirculated oxygen to keep the turbo spinning at high RPMs at all times. The system eliminated turbo-lag at any engine speed and provided fantastic power.

The golden age of rallying couldn’t last forever. Incredibly light and powerful cars combined with poor crowd control at rally events led to a series of accidents, and in 1986 the FIA was forced to bring an end to Group B. By this point the Quattros had somewhere in the region of 590 bhp. As a result, 0-60 mph took only 3.1 seconds.
