Janus,
Cosworth is a famous engine builder with alot of F1 experience under it's belt. The name is the combination of the two founders: Mike
Costin and Keith Duck
worth Apparently founded in 1958.
Related to Ford, here's an excerpt from the cosworth history on their website,
www.cosworth.com:
"...As the 1980s became the 90s, Cosworth continued to provide winning power, with the Ford Sierra Cosworth RS500 taking the 1987 Touring Car world title and the Cosworth-powered Ford Mondeo winning the World titles for Paul Radisich in 1993 and 1994.
In Formula One, the DFV was replaced by the HB which won 11 races between 1989 and 1993, while Nigel Mansell’s 1993 CART championship and Jacques Villeneuve’s 1995 Indy 500 win were both provided by Cosworth power. In 1994, the Zetec V8 F1 engine was introduced and powered Michael Schumacher’s first world driver’s title. And in rallying, the Ford Escort Cosworth notched up numerous wins during the 1990s and the Duratec-R engine in the Focus gave Ford more success, to take Colin McRae to an all-time win record.
Bringing the story to its conclusion, in 2003, Cosworth provides the power to 30% of the Formula One grid, as well as to the entire CART championship and the Ford BP Rallyesport Focus World Rally cars."
