The Hill GH1 was a Formula One car used by Embassy Hill during the 1975 Formula One season. It was designed by Andy Smallman. The car was initially designated as the Lola T371, but when Smallman left Lola to work full-time for Embassy Hill it was renamed as the Hill GH1. GH1 cars participated in 12 World Championship Grands Prix in 1975, with 21 entries in total using six different drivers. Two points finishes yielded 11th place in the World Constructors' Championship, with three points.

Embassy Racing With Graham Hill, commonly abbreviated to Embassy Hill, was a short-lived Formula One team started by two-time Formula One World Champion Graham Hill. The team debuted in 1973 with a customer Shadow DN1 car, and began racing as a constructor with its own chassis in 1975. The team had limited success in three seasons of racing, but everything was cut short by the death of Hill, Tony Brise and some of the team's top personnel in the crash of a light aircraft in the autumn before the 1976 season. The team was sponsored by Imperial Tobacco's Embassy cigarette brand and ran under various names during its time.
