They were one of the most powerful rally cars in the world during the early to mid 80s. They nearly had over 500 horsepower and were either four-wheel drive or rear-wheel drive. The cars during that era of adrenaline-induced rallying include the Ford RS200, the Audi Quattro S1, Peugeot 205 T16, the Lancias 037 and the Delta S4 and the Porsche 959. Sadly the amazing era faced the end in 1986 during the Portugese Rally stage "Lagoa Azul" where a Ford RS200 driven by Portuguese national champion Joaquim Santos crested a rise to find the road blocked with spectators crowding to see the fastest cars come through. He lost control of his Ford RS200 while trying to stop and plunged into the crowd. Thirty-one people were injured and three were killed. But this was not the only crash soon more and more accident occurred in 1986. The end came in 1987 when Attilio Bettega crashed and died in his Lancia 037 during the same year the FIA banned the Group B cars forever but the cars were eventually used to compete in Rally Cross events after the tragic events.
The Group B cars were the best rally cars of all time
