The Ferrari F1/86, Scuderia Ferrari's entrant for the 1986 Formula One World Championship, was designed by Harvey Postlethwaite as a successor to the 156/85. Despite possessing one of the strongest engines in the grid, the F1/86 fell short in competitiveness. It was powered by the Tipo 032 engine, which was the most powerful Ferrari had produced for racing or road use at that time. However, handling issues, particularly in corners, hindered its performance. The F1/86 achieved five podiums but no wins, poles, or fastest laps. The car's lackluster performance led Ferrari to recruit John Barnard from McLaren and transition to the Gustav Brunner-designed F1/87 for the 1987 season, marking the end of Ferrari's use of the 120° V6 turbo engine that had been in use since 1981.
