The motor was mildly tuned, but not supercharged. Type 59 GP wheels were installed.

When the 57G first appeared, it was sensation within the racing community. Bugatti proved the car at many different Grand Prix events, and even won the French Grand Prix at Montlhery due their slippery aerodynamics and light fuel consumption. The following year, at the 24 Hours of Le Mans, Jean-Pierre Wimille and Robert Benoist drove a Type 57G car to victory at Le Mans at an average speed of 85 mph.

A special version of the 57G, called the Type 57S 45 was prepared for the 1957 Le Mans. It used the type 50B engine which was reported capable of 470 horsepower. It featured extra cooling beside the radiator hole and no apertures in the frontwings. Unfortunately, the car only ran in practice and saw little competition thereafter.

After Bugatti's absence from the 1938 Le Mans, Jean finally convinced Ettore to race a single entrant in the 1939 race. The car was a 'tank-line' Type 57C, being much longer than the Type 57G. After Louis Gerard in his Delage retired, Wimille and Veyron were drove to victory and took another Le Mans win for the Type 57 chassis. Tragically, Jean Bugatti died testing the winning car on August 11, 1939. The car was never rebuilt.

Chassis 57367 is the sole survivor of three Tanks made in 1936. It is also one of the most important Bugattis, as this chassis, #57335, won the 24 Hours of Le Mans in 1937. Before this victory, the car won
