não foi porque, após a morte do Toivonen, que estava a preparar-se para se sagrar campeão do mundo, houve uma jogada de bastidores que tirou o campeonato ao Markku Alén
The 1986 season 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.[2] 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 Alén.
