1.High safety and reliability; nice appearance; widely accepted by the market, sold over 10,000 units.
2.Will be optimized according to the local working condition, with the adoption of the unique production processes and technology, with the cathodic electrophoresis' treatment of the bus body, the bus is perfectly fitting the environment of many big slopes, high humidity and cold conditions.
3.Excellent performance in safety due to the usage of Monocoque technology originated from German Kassbohrer.
4.Monocoque body structure is used for lightweight design. Compared with similar models of other manufacturers, the weight is 800-1000kg lighter and more energy-saving.
5.Warm color interior trim design, creating comfortable circumstance for the passengers.
6.Ergonomic driver cabin design ensuring comfort to drive.
7.Abundant options to fulfill different levels of requirement.

Production Line
We boost modernized production workshops, scientific and reasonable U-shaped production line. The advanced TPS production management system and complete production and inspection equipment are the powerful guarantee for the outstanding quality of buses.
Lightweight Monocoque Body
The technologic cooperation with German Daimler Group for more than 20 years established the world's first-class and the China's leading technologic advantage. On the basis of the Monocoque body technology,the body framework is made of 16Mn rectangular pipes so that the body strength is 3~6 times of that of common buses and the weight is lighter by approximately 8% than the buses of same class.
Anti-Corrosion Process
The whole vehicle is welded to the body and frame before electrophoresis to ensure that there are no new solder joints in the assembly process after the completion of the painting, to maximize the electrophoretic corrosion resistance and reduce potential safety hazards; the electrophoretic paint film is denser than ordinary spraying. Stronger focus, super resistance to salt spray, humidity and heat, adapt to changing climatic environment, longer service life of the vehicle and more durable.
Leading Process Equipment
Technological production efficiency and scientific precise process criteria realize the strict supervision on the production processes for the major parts of the buses with double guarantee from the outside to the inside, guarantee the consistently outstanding quality for every bus.
Inspection Capability
The advanced German and American inspection equipment, fully digital inspection line, and finished product testing simulation ground strictly control the quality for every delivered bus.
