The [[Stewart Grand Prix]] team effectively became the Ford works team, and used Cosworth '''CR-1''' engines from its first season in 1997, which was a much lighter version of VJM, ultimately reaching 770&nbsp;bhp at 16,500&nbsp;rpm by 2001. Over the next few years Ford had increased its involvement with the Stewart team, and finally bought the team, renaming it [[Jaguar Racing]] for 2000. Ford pulled out of F1 at the end of 2004, but the team (bought by and renamed [[Red Bull Racing]]) continued to use Cosworth V10 engines until switching to a Ferrari V8 for 2006. [[Minardi]] also used re-badged Cosworth engines until 2005.

[[Williams Grand Prix Engineering|Williams]] began testing the new '''CA2006''' 2.4-litre V8 in November 2005, which produced about 755&nbsp;bhp @ 19,250&nbsp;rpm (314.7&nbsp;hp/L),<ref>{{cite web |url=https://www.grandprixengines.co.uk/Note_108.pdf |title=Grand Prix Engine Development 1906-2000: Cosworth 2006 Type CA Series 6 Eg SO25 |first=Derek |last=Taulbut |access-date=18 January 2021}}</ref> and began using Cosworth [[V8 engine]]s for the 2006 season. In the same year, [[Scuderia Toro Rosso]] used detuned V10 engines based on the 2005 units.

In 2007, however, the company was left without a partner when Williams chose to switch to [[Toyota F1|Toyota]] power, and Scuderia Toro Rosso made the switch to [[Scuderia Ferrari|Ferrari]] engines (as used in 2006 by their mother team [[Red Bull Racing]]).

In Max Mosley's letter following the withdrawal of Honda from Formula One in December 2008, it was announced that Cosworth had won the tender to provide a standard engine to any interested participants. The new engine would become the standard design and manufacturers could opt to use whole units, construct their own from designs provided by Cosworth, or produce their own engine with the caveat that it be limited to the same power as the new "standard" engine.

In 2010 Cosworth returned as the engine supplier for [[Williams Grand Prix Engineering|Williams]] and three new teams; [[HRT Formula 1 Team|Hispania Racing]], [[Team Lotus (2010–11)|Lotus Racing]] and [[Virgin Racing]]. The '''CA2010''' is the same 2.4-litre V8 base of the CA2006 used by Williams, but has been re-tuned for the then-mandated 18,000&nbsp;rpm limit required on all engines, down from its original 20,000&nbsp;rpm implementation.<ref>{{cite web |url=http://www.itv-f1.com/News_Article.aspx?id=46413&PO=46413 |title=Cosworth expects engines to be strong – F1 &#124; ITV Sport |publisher=Itv-f1.com |date=20 July 2009 |access-date=12 July 2010 |url-status=dead |archive-url=https://web.archive.org/web/20100607144147/http://www.itv-f1.com/News_Article.aspx?id=46413&PO=46413 |archive-date=7 June 2010 |df=dmy-all }}</ref> First units were ready and shipped to teams in mid-January for fitting 2 weeks prior to first track testing for the year.<ref name="autosport1">{{cite news|url=http://www.autosport.com/news/report.php/id/80810 |title=autosport.com |publisher=autosport.com |date= 12 January 2010|access-date=12 July 2010}}</ref>
