the most successful group B era driver with a total of seven wins. Beyond WRC Although 1987 saw the end of Group B rally car development and their appearance on the world rally scene, they did not disappear. They were still permitted in regional championships providing they met the limit of 1600cc for four-wheel-drive or were homologated prior to 1984. Future FIA president Mohammed Ben Sulayem was one privateer who contested rounds of the 1987 Middle East Rally Championship in an Audi Quattro A2 and Opel Manta 400. Independent teams would enter the European Championship too, though the limited options of permitted Group B cars were not as competitive or ubiquitous as newer Group A cars. Porsche's 959 never entered a WRC event, although it did compete in the Middle East championship and won the Paris-Dakar Rally in 1986. Peugeot adapted their T16 to run in the Dakar Rally. Ari Vatanen won the event in 1987, 1989 and 1990. Improved Peugeot and Audi cars also competed in the Pikes Peak Hillclimb in Colorado. Walter Röhrl's S1 Rally car won the Pikes Peak International Hill Climb in 1987 and set a new record at the time. Audi used their Group B experience to develop a production based racing car for the Trans-Am and IMSA GTO series in 1988 and 1989 respectively. Many ex-rally cars found homes in European Rallycross events from the beginning of 1987 until the end of 1992. The MG Metro 6R4 and Ford RS200 became frequent entries in national championships. For 1993, the FIA replaced the Group B models in the European Rallycross Championship with prototypes that had to be based on existing Group A models. Group S As well as the cancellation of Group B, the tragedies of 1986 also brought about the scrapping of Group B's proposed replacement: Group S. Group S rules would have limited car engine power to 300 hp (225 kW). To encourage innovative designs, ten examples of a car would have been required for homologation, rather than the 200 required for Group B. By the time of its cancellation, at least four Group S prototypes had been built: The Lancia ECV, the Toyota MR2-based 222D, the Opel Kadett Rallye 4x4 (a.k.a. Vauxhall Astra 4S) and the Lada Samara S-proto, and new cars were also planned by both Audi (the 002 Quattro) and Ford (a Group S modification of the RS200). The cancellation
