The ATS would later be used in the Derrington-Francis project spearheaded by the Rob Walker Racing Team's former chief mechanic, Alf Francis. The car made one appearance at a Formula 1 race, the 1964 Italian Grand Prix, driven Mário de Araújo Cabral, where it retired after 25 laps. This car was subsequently restored in the late 1990s, and has appeared in historic racing meetings since then.
