Newey’s newly designed car, the FW14 with a Renault RS3 3.5 V10 engine made its debut at the 1991 United States Grand Prix held on a street circuit in Phoenix, Arizona but both drivers retired early with gear box issues. By race four in Monaco, things started to come together, however, with Mansell finishing second, while in race six, the team scored a 1-2 with Patrese victorious and Mansell in second place. The 1991 drivers’ championship was won by Ayrton Senna in the McLaren MP4/6, but Mansell and Patrese recorded seven victories between them with Mansell finishing the season as runner up. The Williams-Renault partnership also narrowly missed out on the constructors’ title.
