Mouton placed second in the drivers' championship the next year, behind Opel's Walter Röhrl. The team's victory at the 1981 Rallye Sanremo, with the car piloted by Michèle Mouton, was the first time a woman won a World Championship rally. Audi kept on winning throughout the 19 seasons, although lack of consistent results meant that Ford took the driver's title in 1981 with Ari Vatanen driving a rear-wheel-drive Escort. The Quattro was officially entered in the 1980 Jänner-Rallye in Austria and easily won. While the new car was indeed heavy and cumbersome, its standing starts on gravel and road grip on Special Stages was staggering. IN-NE 3's combined time for all stages on this rally was over 30 minutes quicker than that of the winner.

Registered by the Audi Sport Factory Rally Team, IN-NE 3, as an opening (zero) car, it was driven by professional driver Hannu Mikkola. That year a Quattro was used in Portugal's Algarve Rallye. This belief was shattered when Audi launched a competition car in 1980, the Turbocharged and 4WD Quattro. Car companies were not keen on using 4WD as it was generally felt that the extra weight and complexity of 4WD systems would cancel out any performance benefits. In 1979 the FISA (then the name of the FIA's motorsport regulatory division) legalized four-wheel drive (4WD). Notable cars of the era included the Lancia Stratos HF, the Ford Escort RS1800 and the Fiat 131 Abarth. Major manufacturers competed in Group 4, which required a minimum of 400 examples of a competition car. Until 1983 the two main classes of rallying were called Group 2 and Group 4.

For 1993, the FIA replaced the Group B models with prototypes that had to be based on existing Group A cars, but still followed the spirit of Group B, with low weight, 4WD, high turbo boost pressure and staggering amounts of power. In the following years Group B found a niche in the European Rallycross Championship, with cars such as the MG Metro 6R4 and the Ford RS200 competing as late as 1992. As a consequence Group B was canceled at the end of 1986 and Group A regulations became the standard for all cars until the advent of World Rally Cars in 1997.

But the cost of competing quickly rose and the performance of the cars proved too much resulting in a series of fatal crashes. Group B was initially a very successful group, with many manufacturers joining the premier World Rally Championship, and increased spectator numbers. There was also a Group C, which had a similarly lax approach to chassis and engine development, but with strict rules on overall weight and maximum fuel load. The category was aimed at car manufacturers by promising outright competition victories and the subsequent publicity opportunities without the need for an existing production model. In just five years, the power output of rally cars had more than doubled. Weight was kept as low as possible, high-tech materials were permitted, and there were no restrictions on boost, resulting in the power output of the winning cars increasing from 250 hp in 1981, the year before Group B rules were introduced, to there being at least two cars producing in excess of 500 by 1986, the final year of Group B. Group A was aimed at ensuring a large number of privately owned entries in races.īy contrast, Group B had few restrictions on technology, design and the number of cars required for homologation to compete-200, less than other series. The base model had to be mass-produced (5000 units/year) and had to have four seats. Group A referred to production-derived vehicles limited in terms of power, weight, allowed technology and overall cost. Group B was introduced by the FIA in 1982 as a replacement for both Group 4 (modified grand touring) and Group 5 (touring prototypes) cars.

The short-lived Group B era has acquired legendary status among rally fans and automobile enthusiasts in general. After the death of Henri Toivonen and his co-driver Sergio Cresto in the 1986 Tour de Corse, the FIA disestablished the class, dropped its previous plans to replace it by Group S, and instead replaced it as the top-line formula by Group A. However, a series of major accidents, some of them fatal, were blamed on their outright speed and lack of crowd control at events. The Group B regulations fostered some of the fastest, most powerful, and most sophisticated rally cars ever built and is commonly referred to as the golden era of rallying. Group B was a set of regulations introduced in 1982 for competition vehicles in sportscar racing and rallying regulated by the Fédération Internationale de l'Automobile (FIA).
