BRM skipped the Gold Cup and the teams crossed the Atlantic for the last two races of 1967. At Watkins Glen the two P83s started thirteenth and fourteenth and retired well short of half-distance on laps 35 and 41, both with engine problems. The Mexican Grand Prix would be the last race for the P83, with Spence qualifying twelfth and Irwin fifteenth. Irwin moved up to twelfth before his engine ran out of oil, while Spence, as so many times in 1967, managed to hang around until the end to claim fifth and two extra points.
