The Ferrari 643 was a Formula One car designed by Steve Nichols and Jean-Claude Migeot and was built by Scuderia Ferrari for use in the 1991 Formula One season. Built during May and introduced at the French Grand Prix it initially looked to have the potential to run at the front. Alain Prost qualified on the front row and took the lead, and although he was eventually passed by Nigel Mansell in his Renault powered Williams FW14, a second place in the car's first race looked promising. Aside from almost always being on the front part of the grid, it was not to be, however.
