context_page_description: The World Rally Championship is a rallying series organised by the FIA, culminating with a champion driver, co-driver and manufacturer. The driver's world championship and manufacturer's world championship are separate championships, but based on the same point system. The series currently consists of 14 three-day events driven on surfaces ranging from gravel and tarmac to snow and ice. Each rally is usually split into 15–25 special stages which are run against the clock on closed roads.
  The WRC was formed from well-known and popular international rallies, most of which had previously been part of the European Rally Championship or the International Championship for Manufacturers, and the series was first contested in 1973. The World Rally Car is the current car specification in the series. It evolved from Group A cars which replaced the banned Group B supercars. World Rally Cars are built on production 1.6-litre four-cylinder cars, but feature turbochargers, anti-lag systems, four-wheel-drive, sequential gearboxes, aerodynamic parts and other enhancements bringing the price of a WRC car to around US$1 million.
context_section_description: The 1980s saw the rear-wheel-drive Group 2 and the more popular Group 4 cars be replaced by more powerful four-wheel-drive Group B cars. FISA legalized all-wheel-drive in 1979, but most manufacturers believed it was too complex to be successful. However, after Audi started entering Mikkola and the new four-wheel-drive Quattro in rallies for testing purposes with immediate success, other manufacturers started their all-wheel-drive projects. Group B regulations were introduced in the 1982, and with only a few restrictions allowed almost unlimited power. Audi took the constructors' title in 1982 and 1984 and drivers' title in 1983 (Mikkola) and 1984 (Stig Blomqvist). Audi's French female driver Michèle Mouton came close to winning the title in 1982, but had to settle for second place after Opel rival Röhrl. 1985 title seemed set to go to Vatanen and his Peugeot 205 T16 but a bad accident at the Rally Argentina left him to watch compatriot and teammate Timo Salonen take the title instead. Italian Attilio Bettega had even a more severe crash with his Lancia 037 at the Tour de Corse and died instantly.
  The 1986 started with impressive performances by Finns Henri Toivonen and Alén in Lancia's new turbo- and supercharged Delta S4, which could reportedly accelerate from 0–60 mph (96 km/h) in 2.3 seconds, on a gravel road. However, the season soon took a dramatic turn. At the Rally Portugal, three spectators were killed and over 30 injured after Joaquim Santos lost control of his Ford RS200. At the Tour de Corse, championship favourite Toivonen and his co-driver Sergio Cresto died in a fireball accident after plunging down a cliff. Only hours after the crash, Jean-Marie Balestre and the FISA decided to freeze the development of the Group B cars and ban them from competing in 1987. More controversy followed when Peugeot's Juha Kankkunen won the title after FIA annulled the results of the San Remo Rally, taking the title from fellow Finn Markku Alén.
