At the Italian GP, after Rindt’s tragic death in a practice accident, Ickx took pole but retired with a broken clutch, leaving Regazzoni to take victory after breaking free of Jackie Stewart’s chasing March 701. The domination of the 312B thereafter resulted in two more 1-2 victories for Ickx and Regazzoni, in Canada and in Mexico, either side of a US GP where Ickx had taken pole and set fastest lap.
