For the 1963 Formula One season the Parnell team were using the year old Lola Mk4A, powered by 1962 specification Climax V8 engines. Amon was teamed with the very experienced Maurice Trintignant for the first race of the season at Monaco and his Grand Prix career started with what was to become typical bad luck: Trintignant's Climax developed a misfire, so he took over Amon's car.
