It its launch four bodytypes were available for the Type 57. Three of these were named after mountain peaks in the Alps; the four-seater, two-door 'Ventoux', the four-door 'Galibier' and the two-door 'Stelvio' convertible.For the sportier clients two improvements were added to the Type 57 line-up in 1936. First off was the addition of a supercharger which boosted the power from 135 bhp to 160 bhp. Secondly a shorter and lower 'S' variant was launched, equipped with more powerful versions of the naturally aspirated and supercharged engines. The Stelvio body type was designed and built by French coach-builder Gangloff. The fourth body was dubbed Atalante and was the two-seater coupe variant. With a price twice as high as that of the least expensive Type 57, the Atalante was the most exclusive body of the lot.

A 3.3 liter, twin-cam, straight-eight engine was used to power this vehicle. Even with the heavy saloon bodies, the engine could propel the vehicle to a speed of around 95 mph. The Type 57 and its variants were intended for road going use. However, many made their way onto the racing circuit. Lord Howe drove a Type 57 to a third place finish in the 1935 Tourist Trophy. A Type 57G won the Monthlhery and Reims race in 1936. In 1937, Jean-Pierre Wimille and Robert Benoist drove a Bugatti to victory at LeMans.
