**Judd** is the engine badge name for products of Engine Developments, Ltd., a company founded in 1971 by John Judd and Jack Brabham. Engine Developments was created to handle the needs of the Brabham team, and was later authorized to maintain and rebuild the Cosworth DFV engines.

## Lower formulae/IndyCar

Judd was engaged by Honda to create an engine for the company's comeback to Formula Two in collaboration with Ron Tauranac's Ralt squad as a result of Jack Brabham's long-standing relationship with Honda.

Judd continued to develop new engines for Honda after Formula Two was discontinued at the end of the 1984 season. The Judd *AV*, a turbocharged V8 engine designed for Honda's CART campaign, was the first. Midway through the 1986 season, Galles Racing and driver Geoff Brabham debuted it on the CART circuit. It was initially known as the *Brabham-Honda* and finished fourth in the 1986 Michigan 500. The engine made its debut at the Indianapolis 500 in 1987. Brabham finished second at Pocono and Road America in 1987, and third at the season finale in Miami. The engine became well-known for its dependability and high fuel consumption (especially in 500-mile races). However, it was significantly less powerful than the leading engine of the day, the Ilmor-Chevrolet.

Truesports took over as the major team in 1988, with driver Bobby Rahal, and the "Honda" brand was removed from the powertrain. Rahal took advantage of the engine's dependability in the 500-mile races during the 1988 season, finishing fourth at Indy and second at the Michigan 500. At the 1988 Pocono 500, he won the first and only Indycar race powered by the Judd engine. His ten top-10 finishes helped him finish third in the season points standings. Even after Honda stopped badging the engines, Judd continued to produce improvements for the AV until the early 1990s. When Honda moved into the new Formula 3000 series, Judd again developed the company's engine. Based on the architecture of the AV, the new *BV* V8 was a naturally aspirated variant, and would eventually form the basis for the Judd *CV* Formula One engine.

## Formula One

Judd made the switch to Formula One's newly reintroduced normally aspirated version in 1988, working with March Engineering, which would totally replace turbocharged cars in 1989. Judd saved money by using the existing *BV* V8 as the foundation for their new F1 engine, while also producing a customer engine that could compete on track and in the marketplace with the Ford Cosworth V8s that were standard equipment for the (mostly smaller) teams competing under the new rules. The *CV*, Judd's first Formula One engine, was built to the 3.5-litre engine formula for naturally aspirated engines. The engine shared many design elements with the Judd BV engine, although it was larger, measuring 3.5 litres. During the 1988 season, the 600 bhp (447 kW; 608 PS) Judd V8 was commonly the fastest of the non-turbo engines.

For the 1989 season, Judd developed the all-new narrow-angle Judd *EV*, with a more compact 76-degree *V* angle, rather than the more conventional 90 degrees of the Judd *AV*/*BV*/*CV*, and the Cosworth *DFV* series. Construction of the *CV* continued as a cheaper alternative for smaller teams.
