The 450S Maserati was developed from the earlier 300S. The rest of the world had long since converted to disc brakes, but Maserati stuck with drums, albeit heavily finned.
Le Mans was not Fangio's favourite race, possibly because of the unhappy memories of the 1955 tragedy, which he narrowly avoided, but he agreed to go along to 1957 as reserve driver , and duly notched up the fastest practice time of 3m 51.1 sec.
The race started in hot and dry conditions, and after the opening war of atrition, Behra went into the lead with our subject car. Again Maserati's reputation for fragility struck, this time in the shape of a minor component failure, grease-gaiters, leading to universal joint breakage. Behra was in the lead at the time, and had a consolation prize, being timed at 170.4 mph.
