The Ferrari 156/85, a Formula One car designed by Mauro Forghieri and Harvey Postlethwaite for the 1985 season, was driven by Michele Alboreto and initially by René Arnoux, who was later replaced by Stefan Johansson. Featuring a Ferrari Tipo 031/2 V6 turbo engine, it produced around 750 bhp. The car started the season with promise, showing speed and reliability, but faced increasing fragility and engine failures as the season progressed. This unreliability cost Alboreto the driver's championship, notably highlighted when he drove a lap with his car on fire at the Brands Hatch circuit, symbolizing the car's failure in the championship. Despite these issues, Johansson achieved respectable finishes, but the car's unreliability led to Ferrari finishing as runners-up in the season.
