Frank Williams Racing Cars
Customer Brabham and March entries; ended in financial collapse.
Frank Williams began by entering customer Brabhams for Piers Courage, who finished second at Monaco and Watkins Glen in 1969. Courage was killed at Zandvoort in 1970 and the team spent the next years scraping sponsorship together, running De Tomaso, March and its own Politoys and Iso-Marlboro chassis.
By 1975 the operation was insolvent in all but name. Canadian oil businessman Walter Wolf bought a controlling stake at the end of the year.
2020 — Present2020 to today: new owners, same name
Williams Racing (Dorilton)
US investment ownership; name and Grove base retained.
US investment firm Dorilton Capital bought the team in August 2020 and the Williams family stepped away entirely at the Italian Grand Prix that year. The name was kept deliberately — Dorilton bought the history as much as the entry.
James Vowles arrived as team principal in 2023 to modernise infrastructure that had fallen a decade behind, and Carlos Sainz joined for 2025 as the team rebuilt towards the new regulations.

Wolf-Williams Racing
Walter Wolf buys in; Frank Williams leaves to start again.
Wolf's money bought the Hesketh assets and rebranded the entry Wolf-Williams Racing, with Frank Williams demoted to a management role he found intolerable. The season was poor, and Williams left before the end of it.
Wolf continued alone as Walter Wolf Racing from 1977, which this archive tracks as a separate lineage. Williams walked away with nothing but his address book.

Williams Grand Prix Engineering
Nine constructors' titles as a fully independent team.
Williams restarted in 1977 with engineer Patrick Head and Saudi backing, running a March in the first season and the in-house FW06 from 1978. Clay Regazzoni won at Silverstone in 1979 and the constructors' title followed in 1980, with Alan Jones taking the drivers' championship.
Ground effect, Honda turbos, active suspension and Renault V10s carried the team through the 1980s and 1990s: titles for Jones, Rosberg, Piquet, Mansell, Prost, Hill and Villeneuve, and nine constructors' championships in total.
Frank Williams's road accident in 1986 left him a tetraplegic but he ran the team until 2020. The BMW and Cosworth years after 2006 were lean, and by the late 2010s the family-owned model could no longer fund a competitive car.
