The vehicle has a central wheel drive, and a seat device (19) arranged on a chassis (11). The chassis has a front part (21) and a rear part (23), which are connected to each other in an articulated manner by a joint (25). Front wheels (15) are separately drivable from each other by a motor (27). A drive unit (37) e.g. linear motor, adjusts the front part of the chassis with respect to the rear part to bring central wheels (13) in outside ground contact and the front wheels in ground contact. The central wheels are arranged at an arm (29), and the front wheels are arranged at another arm (31).
