The FW14 made its debut at the 1991 United States Grand Prix.
The car was the most technically advanced car in competition, but various difficulties during the season stymied the team's early progress.
Nigel Mansell and Riccardo Patrese recorded 7 victories between them but the Drivers' Championship was wrapped up by Ayrton Senna in the McLaren MP4/6, which had better reliability.

Williams had the faster car throughout the balance of the season and it provided a run of good form in the mid season for both Mansell and Patrese.
Mansell, in particular, had several retirements due to the then new-for-Williams semi-automatic transmission, with most of these retirements occurring while in a position to win races.
Patrese was impressive on several occasions and retired while leading twice.
McLaren's superior reliability told in the Constructors' Championship as well, as they narrowly took the title from Williams.

A total of 5 chassis were built.
