In 1980, a German car maker, Audi, at that time not noted for their interest in rallying, introduced a rather large and heavy coupé version of their family saloon, installed a turbocharged 2.1 litre five-cylinder engine, and fitted it with four-wheel drive. Thus the Audi Quattro was born. International regulations had prohibited four-wheel drive; but FISA accepted that this was a genuine production car, and changed the rules. The Quattro quickly became the car to beat on snow, ice or gravel; and in 1983 took Hannu Mikkola to the World Rally Championship title. Other manufacturers had no production four-wheel drive car on which to base their response, so FISA was persuaded to change the rules, and open the Championship to cars in Group B. This allowed cars to be much further removed from production models, and so was created a generation of rallying supercars, of which the most radical and impressive were the Peugeot 205 T16, Renault 5 Turbo and the Lancia Delta S4, with flimsy fibreglass bodies roughly the shape of the standard car tacked onto lightweight spaceframe chassis, four-wheel drive, and power outputs reportedly as high as 600 hp (450 kW). Further Group B cars were developed by Ford (the RS200), British Leyland (the Metro 6R4) and many others, but these were less successful.
But this wasn’t enough. By 1984 rallying was all but deregulated, and Audi Sport introduced the Sport Quattro: a shortened, more powerful version of the original coupe, and regulations insisted that 214 were built for the road. With its wheelbase shortened a meaningful 12.6 inches between the B- and C-pillars, the Sport Quattro was more nimble and the bodywork featured numerous GRP and carbon-Kevlar panels. A massive KKK-K27 turbocharger helped increase power to 302hp on the road, while Stig Blomqvist had access to over 450hp in the rally Group B version.
The term "rally", as a branch of motorsport, probably dates from the first Monte Carlo Rally of January 1911. Until the late 1920s, few if any other events used the term. Rallying itself can be traced back to the 1894 Paris–Rouen Horseless Carriage Competition (Concours des Voitures sans Chevaux), sponsored by a Paris newspaper, Le Petit Journal, which attracted considerable public interest and entries from leading manufacturers. Prizes were awarded to the vehicles by a jury based on the reports of the observers who rode in each car; the official winner was Albert Lemaître driving a 3 hp Peugeot, although the Comte de Dion had finished first but his steam powered vehicle was ineligible for the official competition. This event led directly to a period of city-to-city road races in France and other European countries, which introduced many of the features found in later rallies: individual start times with cars running against the clock rather than head to head; time controls at the entry and exit points of towns along the way; road books and route notes; and driving over long distances on ordinary, mainly gravel, roads, facing hazards such as dust, traffic, pedestrians and farm animals.
