Reentering F1 in the British Grand Prix, Rodríguez matched teammate Amon's pace in practice and led Amon by a whisker in the race. The uncompetitive 312s ran midfield until Rodríguez's car broke and Amon's engine blew for the second race in a row. Given the hopelessness of the 312 V12, the frustration of his drivers, and the slow progress with getting the new flat-12 F1 car ready, Enzo Ferrari would rather have run two Italian drivers for the rest of the season, but the Brambilla brothers, Vittorio and Ernesto, proved too slow. So, Ferrari ran Rodríguez in the last four races of the season, in NART American racing colours for the North American races, but still, effectively, as a Ferrari works team. In the underpowered car, Rodríguez managed a fourth in 1968; sixth in 1964, 1967 and 1970; and seventh in 1965 and 1969; places in his six home races in Mexico, but Ferrari didn't offer him a ride for 1970.
