The Ferrari 641, also known as the Ferrari F1-90, was Ferrari's competitive entry in the 1990 Formula One World Championship. An evolution of the 1989 Ferrari 640, the 641 was initially designed by John Barnard and further developed by Steve Nichols. It featured a potent 3.5-litre V12 engine and was notably among the best handling cars on the grid, acclaimed by driver Alain Prost as the best car of that year. The Ferrari 641 marked a significant achievement for the team, with Prost and teammate Nigel Mansell securing six Grand Prix wins between them during the season.
