By the San Marino Grand Prix, the first THL2-Ford was completed for Jones, but was only able to qualify 21st in comparison to Tambay's eleventh in the THL1-Hart. Jones commented during qualifying that the THL2 was a great handling car, all that was needed was more horsepower from the new engine. Tambay received his first THL2 at Monaco and quickly qualified eighth with it, only to crash out of the race in the final eleven laps. Tambay was lucky when he crashed at Monaco that it was on one of the circuits many slow turns. His car rode the wheel of Martin Brundle's Tyrrell at Mirabeau and flipped over, hit the barrier and landed back down on its wheels. Another couple of feet higher and he would have cleared the barrier. Although still out qualified by Tambay, Jones was in position to finish his first race with the team in Belgium before his car ran out of fuel in the closing laps. Jones managed to see the finish of the Canadian Grand Prix, but his team mate was injured in a heavy crash during the warm-up.
