Karosa ŠM 11 is completely different from its predecessor, Škoda 706 RTO, which had engine in front and two doors. ŠM 11 is model of Karosa Š series. It is derived from Karosa ŠL 11 intercity bus, and also unified with long-distance coach Karosa ŠD 11. Body is semi-self-supporting with frame and engine with automatic gearbox in the middle, between the wheels. Only rear axle is propulsed. Front axle is independent, rear axle is solid. All axles are mounted on air suspension. On the right side are three folding doors (first are narrower than middle doors). Inside are used leatherette seats. Drivers cab is not separated from the rest of the vehicle. In the rear part is room for a pram or wheelchair.
