Click here to download printer friendly version Benetton made its Formula 1 debut in the 1986 season with the B186 after it took over the remains of the Toleman team. It was powered by a straight 4 cylinder Turbocharged engine. The chassis was develloped through the season and that led to Benettons first win at the end of the season in the Mexican GP. This was tire manufacturer Pirelli's only win. Drivers were Gerhard Berger and Teo Fabi.
