Hart

Hart Racing Engines, commonly referred to simply as Hart, was a manufacturer of motor racing engines founded in 1969 by eponymous engineer and former racing driver Brian Hart.

While their initial business came from tuning Ford Cosworth engines, the withdrawal of Ford from the lower Formulae allowed for Hart to begin selling self-built Formula Two engines to interested teams. Hart eventually made the step up to Formula One in 1980 with B&S Fabrications, who were among the earliest adopters of turbocharged engines, and only the second after Dywa-Renzo to do so without the backing of a major automobile manufacturer. The engine program eventually received support from British Leyland and its marque Rover in 1982 and supplied four teams that year - Spartec (B&S), March, Osella and Toleman (who had their engines rebadged as Triumph).
