Trojan was anautomobile manufacturer^[1] and aFormula One constructor, in conjunction with AustralianRon Tauranac,^[2] from theUnited Kingdom.

The car producerTrojan Limited was founded byLeslie Hounsfield in 1914 inClapham, South London, and later inPurley Way,Croydon,Surrey.^[3] It produced cars and especially delivery vans until 1964.

Around 1960, the Trojan business was sold to Peter Agg who importedLambretta scooters for the British market.^[1][3][4] In 1962, the rights to manufacture theHeinkelmicrocar were acquired^[1] and the production line^[5] was moved fromDundalk,Ireland to Croydon. Production then commenced, renaming thebubble car asTrojan Cabin Cruiser. Production continued until 1965, when some 6,000 cars had been produced.^[5] Speaking toMotor Cycle magazine in 1965 after cessation of production, Peter Agg confirmed that a 1962 British government reduction inpurchase tax from 50% to 25% aligning car taxation with three-wheelers and motorbikes, had given a big boost to the cheaper end of the car market, adversely affecting sales of the economy-sector three-wheeler, making continued production uneconomical.^[6]

Also in 1962, Trojan acquired theElva sports car business and started to make the Mk IV Elva Courier.^[1] This in turn led to the manufacturing ofMcLaren racing cars until vehicle production finally ceased in the early 1970s. Trojan Limited still exists as an independent company though the factory was sold in the 1970s.

The Trojan T101Formula 5000 model met with success whenJody Scheckter won the1973 SCCA L&M Championship driving a T101 and aLola T330.

They participated in eight grands prix,^[2] entering a total of eight cars. In 1974,David Purley won theBrighton Speed Trials driving a Trojan-Chevrolet T101.^{[citation needed]} While Formula One remained the major series, sports cars were also fashionable on either side of theAtlantic. TheMcLaren M1 was put into production by Peter Agg's Lambretta Trojan Group inRye, Sussex. They would make 200 McLarens during ten years.^{[citation needed]}
