Xtrac Limited, also known as Xtrac Transmission Technology, is a British engineering company founded in 1984 by the former Hewland engineer Mike Endean to make 4WD systems and gearboxes for rallycross and later rally and racing cars. Endean, together with Chris Goddard, who had been working on the electronic components essential to the system, in 1983 developed the first Xtrac 4WD system, for Norwegian rallycross star Martin Schanche. Schanche had thought up the idea of a changeable hydraulic 4WD system and financed its development. This 560bhp so-called Xtrac No. 1 was bought by Endean, in the mid-1990s, who raced it himself for many a year in carsprints and hillclimbs.
