A Deutsch & Bonnet driver in DB-Panhards in Formula 2 races and hillclimbs around France in the early 1950s, Bayol's best result was a fourth place at the 1951 Circuit de Cadours. In 1952 he ran his own OSCA F2 car, built by the Maserati Brothers, and finished fourth at Pau. The following year both Bayol and Louis Chiron ran the cars and Bayol was fourth again at Pau and was on pole at Albi. He qualified for the French GP at Reims that year but did not finish. He later won the Circuit du Lac at Aix-les-Bains against a good field.Bayol raced in the Italian GP that year and in 1954 he joined the Gordini factory team with Jean Behra and finished fifth in the first race in Argentina. He finished fourth (as usual) at Pau but then edged out of the team. He returned the following year but suffered a string of mechanical failures. In 1956 he raced a few times but then disappeared from single-seater racing.
