The IV Gran Premio Di Monza at the Autodromo di Monza was the first race for the 4.9-litre twin overhead cam, supercharged straight eight-cylinder Type 54s, which were the largest capacity Bugatti Grand Prix cars ever produced. </p><p> In the heats the 300hp cars – which were capable of a top speed of 150mph (240km/h) – dominated, with Achille Varzi finishing first and Louis Chiron second. However, despite challenging for the lead and setting what would prove to be the fastest lap of the race at an average speed of 102mph (164km/h), two burst tyres for Varzi in the final affected his chances of the overall win. He recovered to finish third.
