Boutsen also went on to notch up his second victory at the final race of the year in Adelaide, again in atrocious weather conditions. It was also a great year for Patrese. He appeared on the rostrum six times, led several races, finished third in the Drivers' World Championship and helped the team to runner-up spot in the Constructors' World Championship.

Mansell continued on to became the first driver to win the opening five races of a season. His record breaking did not stop there and he became the first driver to win nine races in one season and to be on pole 14 times. His win at the British Grand Prix was his 28th, beating Jackie Stewart's record for the British driver with the most Grand Prix victories.

When Mansell came second in Hungary he clinched the Drivers' World Championship, the first British driver to do so since James Hunt in 1976. In Belgium Williams and Renault took the Constructors' title, the first ever for Renault, and to end the winning year Patrese finished runner-up to Mansell for the Drivers' crown. The car was fitted with the Renault RS3C engine initially, but in the latter part of the year the RS4 was used.

For 1993 it was all change in the driver line-up, with French three-times World Champion, Alain Prost, and Williams test driver, Damon Hill, taking over from Mansell and Patrese. They carried on where Mansell and Patrese left off, retaining the Constructors' title, while Prost clinched his fourth drivers' title and Hill won his first Grand Prix in Hungary.

But soon after clinching the title Prost decided to finish his career as a driver allowing three-times World Champion, Ayrton Senna, to join the Williams team. So the 1994 championship battle started with the new look Rothmans Williams Renault team and drivers, Ayrton Senna and Damon Hill, supported by test driver, David Coulthard.

For this race Hill was partnered by David Coulthard, who drove car No. 2 for eight of the remaining races. For the other four races in France, Spain, Japan and Australia Nigel Mansell came back from the USA, where he was racing in the Indy Car series. After the win in Barcelona, Hill scored another five victories but lost the championship by a single point to Michael Schumacher following a controversial collision at the last race in Adelaide, which was eventually won by Mansell. In such a tragic year it was testimony to the strength of the team that they retained the Constructors' World Championship, to close a season that will never be forgotten.

For 1995 it was Hill and Coulthard who drove for the team in the Williams Renault FW17 and between them notched up five victories, with the young Scot taking his first Grand Prix win in Portugal. Hill was the only driver to challenge Schumacher for the drivers' title, but had to accept defeat when the German won the title for the second year at the Pacific Grand Prix in Aida.
