Hoffmann's Formula One career was hindered by the financial problems of the Fittipaldi team, and he drove the team's second car when realistically the team could only afford to run one. This meant Hoffmann only entered certain selected races, and ultimately the second car was dropped altogether. He entered four Grands Prix in 1976, did not qualify for three of them and an eleventh place at Interlagos was the best result achieved. In 1977, Hoffman competed at Buenos Aires (retired, engine) and again at Interlagos where he finished seventh, two laps behind the winner. However, that was Hoffman's last race in Formula One, as the second Fittipaldi entry was withdrawn.
