When Graham Hill decided to form his own team in 1973 with himself as driver and headcook and bottle-washer he was heavily sponsored by Embassy Cigarettes. He bought one of the first of the new Shadow cars and it was actually assembled away from the Northampton factory of Shadow Cars, they merely supplying all the bits and pieces. This was Shadow DN1/3A which Hill raced throughout 1973, rebuilding it and up-rating it during the season. For the 1974 season his Embassy-backed team enlarged to a two-car effort and a contract was made with Eric Broadley to supply Lola cars to Formula One specification from what was basically the current Formula 5000 model. This arrangement continued throughout 1974 and for 1975 Graham Hill has branched away into the manufacture of his own cars, designed by Andrew Smallman. The change from Lola cars to Hill cars was effected smoothly and amicably, with a lot of assistance from Broadley, but now the Hill team are constructors in their own right. Needless to say throughout this era of special-building the power unit has been the Cosworth DFV and the transmission the ubiquitous Hewland 5-speed with mountings for inboard rear brakes.
