Bugatti introduced their supercharged version of the Type 57, the Type 57C, in 1936. The 'C' designation comes from the French word for supercharger: Compresseur. As with the Base Type 57, the 57C was available in a handful of body styles, including the Type 57C Atalante. It was common at the time for Type 57 owners to have Bugatti fit the supercharger to Type 57 and Type 57S models after their construction, so while a car may be fitted with a supercharger, it may not have left the factory with one.
