Cosworth is a high-performance engineering company founded in London in 1958, specialising in engines and electronics for automobile racing (motorsport), mainstream automotive and defence industries. Cosworth is based in Northampton, England, with North American facilities in Torrance, CA, Indianapolis and Mooresville, NC.
The company was founded as a British racing internal combustion engine maker in 1958 by Mike Costin and Keith Duckworth (COStin and duckWORTH).
Both of the co-founders being former employees of Lotus Engineering Ltd., Cosworth initially maintained a strong relationship with Colin Chapman and the initial revenues of the company came almost exclusively from Lotus. When the company was founded in 1958, Duckworth left Lotus, leaving Costin (who had signed a term-employment contract with Chapman) at the company. Until 1962, Costin worked on Cosworth projects in his private time, while being active as a key Lotus engineer on the development of Lotus 15 through 26 (Elan), as well as leading the Team Lotus contingent at foreign races as evidenced by the 1962 Le Mans Lotus scandal.
The first Cosworth-designed cylinder head was for SCA series with a SOHC reverse-flow configuration similar to the Coventry Climax FWE engine. A real success was achieved with the next gear-driven DOHC four valve FVA in 1966, which, with a help from Chapman, convinced Ford to purchase the rights to the design and sign a development contract including an eight cylinder version. This resulted in the DFV, which dominated Formula One for many years.
From this time on, Cosworth was supported by Ford for many years, and many of the Cosworth designs were owned by Ford, and named as Ford engines under similar contracts. Another success by the BD series in the 1970s put Cosworth on a growing track. Cosworth’s 176 F1 wins make it one of the most successful engine manufacturers to have raced in Formula One, second only to Ferrari.
The company went through a number of ownership changes during the next decads. The current Cosworth Group is owned by Champ Car World Series owners Gerald Forsythe and Kevin Kalkhoven. Good news is, Cosworth is suppling engines to one F1 team again.

Ford Escort RS Cosworth
The Ford Escort RS Cosworth was a sports derivative and rally homologation special of the fifth generation European Ford Escort. It was designed to qualify as a Group A car for the World Rally Championship, in which it competed between 1993 and 1998. It was available as a road car from 1992-1996 in very limited numbers. It was instantly recognisable due to its large “whale tail” rear spoiler. The main selling point was the Cosworth YBT engine, a highly tunable turbocharged 2-litre engine which had an output of 220 PS (162 kW; 217 hp) in standard trim. Tuning companies have achieved power outputs of even over 1,000 hp.It was also widely acknowledged to have excellent handling.
Max power of the street version is 225 hp (168 kW) at 6,250 rpm, while torque is 310 N·m (229 lb·ft) at 3,500 rpm on 95 ron gasoline. Max speed is 232–237 km/h (144–147 mph) (without the big rear wing),while the 0-100 km/h sprint takes 5.7 or 6.1 seconds.The slower acceleration time is for the heavier “Lux” edition.
The Escort Cosworth was the first mass production car to produce downforce at the front and rear (at front 45N at 70 MPH, adjustable splitter in middle position, rear 190N, with the large wing)
