 With the 1952 World Championship being run to Formula Two specifications, Alfa Romeo did not have a car for the new formula and were unable to use their supercharged Alfettas, so they withdrew.As a result, the defending champion found himself without a car for the first race of the championship and remained absent from F1 until June, when he drove the British BRM V16 in non-championship F1 races at the public road circuits at Albi in France and Dundrod in Northern Ireland.Fangio had agreed to drive for Maserati in a non-championship race at Monza the day after the Dundrod race, but having missed a connecting flight he decided to drive through the night on pre-motorway mountain roads through the Alps from Lyon, arriving half an hour before the start.
