Cosworth

Cosworth is a British motor manufacturer based in Northampton. With Cosworth ( Sports ) motors are developed to find both in road cars (Ford Sierra / Escort Cosworth ) and in race cars use. The company is known for its long-standing commitment to Formula 1.

Company History

Founded in 1958 by Mike Costin Cosworth and Keith Duckworth. The company's name is composed of the two last names of the founders.

With the development and distribution of performance-enhancing components for the " Kent " engine of the Ford Anglia 105 E for the English Club Racing Cosworth has established itself almost unrivaled in a short time in this market. Starting from the sale of parts and fully assembled racing engines developed Costin and Duckworth different cylinder heads for all engine variants of the series of the Ford Kent engines. International they made a name for himself with racing engines such as the Cosworth DFV.

1980 United Engineering Industries bought the company. Duckworth went into retirement in 1989, Costin remained until 1990 in the company. 1989 Cosworth was acquired together with United Engineering Industries of Carlton Communications and sold in 1990 at the Vickers Group. After being sold to Audi 1998 Cosworth was divided into Cosworth Racing and Cosworth Technology. Cosworth Technology, further, inter alia engines for Aston Martin (before relocation to Cologne, Germany), Audi RS4 (B5 ) and Ford Focus SVT builds, remained with Audi, while at Cosworth Racing Ford took control. 2004 Cosworth Technology was sold to the Mahle Group in Stuttgart and renamed Mahle Powertrain.

Formula 1 engines

The Ford - Cosworth engine was the most successful Formula 1 naturally aspirated (155 victories 1967-1983, based on the DFV).

It was developed based on the new 3-liter regime from 1966 to 1967 for Lotus debut in the Dutch Grand Prix at Zandvoort. He won his first race there the same by the Lotus driver Jim Clark.

Costin and Duckworth initiated the communications from two cylinder blocks and heads of FVA engine 1966 developed for Formula 2, which were mounted on a newly developed crankcase so that a V8 engine was built ( DFV Double Four - Valve motor, double four-valve engine ). This engine was the first engine used in Formula 1, which was fully supporting integrated into the chassis and - combined as powertrain with ZF, Hewland or Colotti transmissions - the rear suspension recorded. This was the Lotus 49, the first representative of this still current design.

Soon Cosworth supplying not only the Lotus team. In the early 1970s drove down to Ferrari almost all teams with a Cosworth engine. For the wedding of the turbo engines from the early / mid 1980s, the engine could enter no success, so a speed- limited version was derived for the F3000. The turbos were banned after 1988. In Formula 1, the HB engine replaced the DFV engine or its last stages of development under the 3.5 liter regulations, the DFZ or DFR, and won eleven races between 1989 and 1993. In 1994, the new engine Cosworth Zetec V8 was F1 presented. With this engine, Michael Schumacher won his first world championship in Formula 1

In the 2004 season, the Jaguars, the Jordan and Minardi team with Ford -Cosworth TJ2004 engines that met the then current 3-liter V10 engine formula drove. With the departure of Ford from Formula 1 at the end of the 2004 season Cosworth was sold to the active in the Champ Car series Kevin Kalkhoven and Gerald Forsythe. In the 2005 season the Red Bull Racing, and Minardi went with Cosworth engines. For 2006, Cosworth had signed a contract with the Williams team, which was associated with the development of the 2.4-liter V8 engine. The Minardi successor team Scuderia Toro Rosso went in 2006 for financial reasons with speed- reduced 3-liter V10 engines of the previous year.

Cosworth won for the 2007 Formula 1 season no team as customers, so that the name Cosworth temporarily disappeared from the premier class. For the 2010 season, the traditional racing team Williams F1 could be won as a buyer for the engines and the newly registered team Hispania, Virgin and Lotus. Since the development of the new V6 engines is extremely costly for the 2014 Formula 1 season, Cosworth decided not to launch a V6 engine and thus to withdraw from Formula 1 at the end of the 2013 season.

Motor types

The company Cosworth was also known by many other engines. Most of them are based on an engine block from the series production of Ford, for at Cosworth four-valve cylinder heads were developed.

• Cosworth MAE: (Modified Anglia Engine) 1000 cc Kent engine with modified cylinder head (from about 1961)
• Cosworth SCA ( Single Cam Series A) cylinder head with overhead camshaft (from 1963)
• Cosworth FVA ( Four Valve Series A) cylinder head with two overhead camshafts and 16 valves based on the 1600 cc Ford Lotus Cortina L engine block ( from 1967)
• Cosworth BDA ( Belt Drive Series A) cylinder head with two belt driven camshafts and 16 valves ( from 1970). The engine block was acquired by Kent engine from Ford. This OHV engine has a laterally located in the engine block camshaft and a timing chain. The engine block was modified to drive with a toothed belt, the overhead camshafts developed by Cosworth cylinder head. The engine became widespread in motorsport, in series production he was at Ford for the Escort RS1600 (first series, only the United Kingdom), the Escort RS1800 (second series, also UK only ), and for Group B Rally world Cup developed Ford RS200 used. With the RS1800 Björn Waldegård 1979, Ari Vatanen in 1981 World Rally Champion. The displacement of the RS1800 was enlarged to 2 liters, the engine so made ​​about 180 kW ( 250 hp) at 7,000 min -1. BDA should also replace the communications during the turbo era in the formula 1, proved to be not equal, due to the construction of the thermal load and high speeds. Zakspeed used the engine in the Capri Turbo in the DRM and thus won countless victories and the championship with Klaus Ludwig in the season 1981. The one with a turbocharger of Kuehnle, Kopp & Kausch (KK & K ) supercharged engine developed 1.8-liter 441 kW (600 hp) at 9000 min -1.

• Cosworth YB: Based on the 2.0-liter OHC engine from Ford Cosworth first developed in-house a 16V cylinder head with two overhead camshafts. Ford took over the cylinder head with respect to the motor sport activities with the Ford Sierra in the World Rally Championship and in various touring car championships. After the engine for the homologated Sierra RS Cosworth with Garrett T3 turbocharger ( YBB type, red valve cover ) the purposes for motorsport again revised and limited to 500 copies Sierra RS500 followed. This vehicle was converted by Tickford in the UK and was only available as a right-hand drive (Type YBD, red valve cover ). With the second generation model of the Sierra RS Cosworth was only as a notchback sedan available, the rear-wheel drive version without Kat was also equipped with the YBB, the all-wheel version with G- Kat was delivered with slight modifications to the engine ( YBG, green valve cover ). The Escort RS Cosworth was first also comes with the YBG the Sierras (although with blue valve cover ), later versions were given a newly revised engine ( YBP, gray valve cover ) with the smaller T25 turbocharger from Garrett, also known as HTT - Cosworth the HTT stands for high torque turbo, turbo which means high torque. The response has been improved by the smaller loaders and the torque was already at lower speeds to. The YBP was Uniquely equipped with a Cosworth Ford EFI fuel injection and a twin spark ignition, with the remaining engines all received an engine control by Weber - Marelli and a contactless ignition distributor. The models without catalytic contributed in production configuration 150 kW ( 204 hp), the vehicles with G- Kat 162 kW (220 hp), motor sport services in excess of 500 horsepower were achieved in the 80s and 90s. While the vehicles were only moderately successful in spite of plant deployment in the World Rally Championship, the Sierra Cosworth 4x4 and Sierra RS500 celebrated on the round and long-haul countless victories and championships at national and international championships.
• Cosworth FB: For the Ford Scorpio were developed for the 2.9 -liter V6 engine, four-valve cylinder heads. Since the vehicle was not related to motorsports, was no need to add Cosworth in the model designation, the cars were sold as Scorpio 24V. In the first Scorpio FBA, of the type designation BOA helped Ford made ​​, 143 kW ( 195 hp). In the second series of the FBC was used, whose name was BOB at Ford. This engine produced 150 kW ( 204 hp). The vehicles were only available with automatic transmission.
