Engine and automatic transmission are located in the left rear corner of the bus. Inside are used plastic Ster seats. Rear axle is VOITH brand, as well as medium axle, the front axle is of its own production with independent wheel suspension. Only third C axle is propulsed, meaning that this articulated bus has pusher configuration.

On the right side of the bus are four doors.
