Williams Team Profile
Nine times a Constructors' Champion, seven times a Drivers', Williams last tasted success in 1997.
Since then the team, one of F1's most successful ever, has been in a steady decline. 2019 and 2020 were their worst campaigns yet.
Williams arrived on the Formula 1 grid in 1977, racing a March chassis. The following year the first FW was born and the team bagged their first points, P4 at the South African GP, and first podium with Alan Jones second in the United States.
So began Williams' epic rise with the team winning its first championship double in 1980 and following that up with a Drivers' crown in 1981 and the Constructors' a year later.
In its 43-year history, the team has amassed 114 grands prix wins, 312 podiums and 128 pole positions.
The last titles came in 1996 and 1997 when the team secured both the World title and the Constructors' with Damon Hill and then Jacques Villeneuve.
But while Williams has basked in a many a high, the lows have been heart breaking.
Team owner Frank Williams was left paralysed when he was involved in a serious car crash on the way back from an F1 test in 1986.
Eight years later they introduced triple F1 World Champion Ayrton Senna to the fold. The Brazilian died when he crashed at the San Marino GP.
Then head of engineering Patrick Head and Williams' chief designer Adrian Newey were charged over his death.
Williams' level of competition yo-yoed in the ensuing years before a switch of design philosophy under the guidance of Paddy Lowe cost them dearly in 2018.
The team slumped to their worst seasons, at least in terms of results, bottom of the pile two years running with just one point in 2019.
Deputy team boss Claire Williams called it their rock bottom, promising that 2020 would be better - or at least a step in the right direction.
Technically it was. Although the team finished the 2020 season with no points for the first time ever as a constructor, Williams' overall competitiveness was an improvement as they regularly battled Haas and Alfa Romeo.
George Russell was also a shining light, regularly outperforming the FW43 to make Q2.
During the 2020 season the Williams family announced that they were looking for outside investment to help the team recover up the grid. They ended up selling the entire team though to Dorilton Capital, with the Williams family ending their involvement following the Italian Grand Prix.
Dorilton said they would be retaining the famous Williams name, along with Russell and Nicholas Latifi for the 2021 campaign.
