Setra[1] is a German bus brand of EvoBus GmbH, itself a wholly owned subsidiary of Daimler Truck AG.

It is also possible that, with an eye to export markets, the company was mindful that for non-German speakers, the name "Kässbohrer" is difficult to pronounce.

Until 1995 the firm operated under the name Karl Kässbohrer Fahrzeugwerke GmbH, but in that year economic difficulties enforced its sale to Daimler-Benz AG (between 1998 and 2008 known, especially in the United States, by the name of its holding company Daimler Chrysler).

The first Setra coach, the Type S8, so called because it contained eight rows of seats, was introduced in April 1951 at the French Internationale Automobile-vouz.

It simplified the production process and created a range of passenger-focused possibilities regarding the floor level in the passenger and driver/crew sections, and for high-floor layouts, flexible use of the underfloor area.

Only a few types were given different designations, for example, the S 250 Special (a modified S 215 HD which was also offered as an entry-level model after the introduction of the 300 series) and the S 300 NC (a former low-floor city bus as a predecessor of the Mercedes-Benz Citaro).
