History of the Mercedes-Benz Cito

The Cito was designed as a small low-floor bus for routes that did not need a full-size vehicle. Its diesel engine sat above the rear axle and drove a generator, with electric motors moving the bus, an arrangement then rare among buses; the plan was to add a hybrid or a fuel cell version at a later stage.

It was sold in three lengths of 8,100 mm, 8,900 mm and 9,600 mm, all 2,350 mm wide, with capacities of 31, 34 or 38 passengers. Production ran from 1999 to 2003, and the model was replaced in 2006 by the short-wheelbase Citaro K. Examples remained in service in several European countries, among them France, Belgium, the Czech Republic and Ukraine.
