Bugatti Type 55 1931

The 1931 Base version represents the original introduction of the Type 55 model and is not distinguished from other mechanical versions during its brief production span. Changes over this period mostly involve bodywork commissions, finishes, or minor technical adjustments, without a clear renewal or segmentation. This Base version is the starting point of the Type 55 family, produced until 1935, maintaining the original technical character and a 2.3-litre supercharged engine. Visible differences among examples typically concern body styles rather than notable mechanical evolution.

The term “Base” refers to the cataloged 1931 Type 55 version, without specific indication of a distinct finish or performance level. The model adheres to the common Type 55 mechanical setup, featuring its 2.3-litre straight-eight engine with a supercharger. Major variations among examples lie in their bodywork: the factory two-seater roadster is the most renowned, while some models also exist as coupes or with coachwork by independent firms, leading to differences in door presence, windshield shape, or proportions. These choices are unrelated to the Base version itself.
