Brian Hart Ltd.


Brian Hart Ltd., also known as Hart and Hart Racing Engines, was a motor racing engine manufacturer that participated in 157 Formula One Grands Prix, powering a total of 368 entries.

Founded in 1969 by British engineer Brian Hart, Hart initially concentrated on servicing and tuning engines from other manufacturers for various independent British teams at all levels of motorsport. Hart found particular success with developments of Ford's FVA engine, eventually leading the large multinational company to approach the small independent to develop the Ford BDA 1.6 L engine for the 2.0L class. The European Formula Two title was won in both 1971 and 1972 with Hart-built Ford engines, and the 2.0 L BDA engine would go on to power the majority of Ford's 1970s rallying successes.

With Ford's withdrawal from F2 in the mid-1970s, Hart began to concentrate on building their own designs. The first engine to bear the Hart name alone was the twin-cam, four-cylinder Hart 420R F2 unit, which appeared in 1976 and would go on to power race-winning cars until the end of the decade. In 1978, the Toleman team agreed to a partnership program, with Toleman providing finance to develop further Hart engine designs. The fruits of this collaboration resulted in Toleman taking a one-two finish in the 1980 European F2 Championship.

For 1981 Hart followed Toleman into Formula One, with an inline four-cylinder 1.5 L turbo engine named the 415T. However, the year was a disaster, with Brian Hart's small operation failing to keep pace with better-funded outfits. Toleman cars only qualified to race twice. Hart persisted though, with the best result from the five-year relationship with Toleman coming when Ayrton Senna took second place at the 1984 Monaco Grand Prix and Toleman claiming 7th in the 1984 Constructors Championship. Teo Fabi also took pole position in a Toleman-Hart at the 1985 German Grand Prix, the first of only two F1 poles by a Hart-powered car.
