Diatto began in Turin in 1835 as a carriage-building business before entering automobile production in the early 20th century.
Its automotive identity is most often associated with a flowing Diatto script used on radiator badges, bodywork, and period advertising, commonly paired with formal badge shapes that suited luxury and competition cars of the 1910s and 1920s. Surviving historical examples show a restrained, coachbuilt visual language rather than a modern corporate logo system, reflecting the brand's origins in bespoke construction and early Italian performance engineering.
