Judd is a name brand of engines produced by Engine Developments Ltd., a company founded in 1971 by John Judd and Jack Brabham in Rugby, Warwickshire, England. Engine Developments was intended to build engines for Brabham's racing efforts, and became one of the first firms authorised by Cosworth to maintain and rebuild its DFV engines, but has since expanded into various areas of motorsport.

In 1988, in conjunction with March Engineering, Judd made the move into the recently reintroduced normally aspirated variant of Formula One, which would completely replace turbocharged cars in 1989. 

The first Formula One engine developed by Judd, the CV, was built to the 3.5 litre engine formula for naturally aspirated engines. The engine shared many design features with the Judd BV engine, but was expanded to 3.5 litres. March Engineering were the first team who signed to use the Judd CV. Reigning World Constructors' champion Williams was later forced also to turn to Judd, after they lost their supply of Honda engines for 1988. In addition, Ligier also bought CVs for use in the 1988 season. Judd powered cars finished in podium positions four times during their debut season, with Williams' lead driver, Nigel Mansell, scoring Judd's first podium when he finished second at the 1988 British Grand Prix.
