At the third race of the season, the South African Grand Prix, Stommelen drove the new T371 while Hill continued with the T370. However, he had an accident in practice and could not qualify for the race, thus Brazil was the last race for the T370 with the Embassy Hill team as two GH1 cars were available for the Spanish Grand Prix, the T371 having been renamed by that time. During qualifying for the Monaco Grand Prix, Hill (the team's sole entrant) struggled to qualify the GH1 and made another attempt in a T370 but was unable to qualify that car either. Hill subsequently retired from driving and the T370 made no further appearances at Grands Prix, although it was an unused spare car on a few occasions throughout the rest of the season.
