Group B (4WD): 1982 - 1986
As the World Rally Championship rolled into the 1980s, the rear-wheel-drive cars such as the Ford Escorts, Fiat 131s and Lancia Stratos were pushed aside to make way for a new era: Group B.
Group B welcomed some of the most spectacular rally cars the world had ever seen, boasting four-wheel-drive and in some cases over 500 brake horsepower. Sources at the time claimed that a Group B car could accelerate from 0-60mph (96km/h) on a gravel road in just 2.3 seconds.
Although the FIA had made four-wheel-drive legal back in 1979, many manufacturers assumed that it was simply too complicated and would not be competitive. However, in 1982, Audi wheeled out its brand-new Quattro and enjoyed immediate success.
