Edwards's wrist had not properly healed, so Rolf Stommelen replaced him for the remainder of the season. Stommelen qualified well for the Austrian Grand Prix in 13th with Hill down in 21st, but the German suffered a puncture and had an accident while Hill finished 12th. In Italy Stommelen again outpaced Hill as they started 14th and 21st, but his suspension failed at half-distance while Hill went on to finish eighth, just one lap down on the winner Ronnie Peterson. Heading over to North America for the last two rounds, Stommelen qualified and finished 11th at the Canadian Grand Prix with Hill starting 20th and finishing 14th. For the final race of the 1974 season, the United States Grand Prix, Stommelen again outqualified Hill (21st and 24th), but Hill brought his T370 home in eighth while Stommelen struggled with the car, finishing 12th and last, five laps adrift of the winner Carlos Reutemann.
