The lightweight city bus ZK6120HNG built with great efforts rolled off the line on December 22, 2010.

The curb weight of the city bus is 10.38 tons, which is the lightest one among the counterparts with the same length and configuration in China’s bus industry. Adopted brand new appearance, the bus is 11.56-meter long with integral structure, leaf spring and low entrance. The loading capacity is increased by 20% while fuel consumption reduced by more than 5%.

Optimizing structure through accurate CAE analysis, ZK6120HNG city bus adopts high-strength steel, ensuring the strength and stiffness of frameworks while reducing the overall weight. Meanwhile, the durability, safety and NVH performance of the bus have not been affected. With the platform-based design way, the structure can be expanded, laying a good foundation for the subsequent development of 10.5-meter leaf-spring low entrance city bus and 12-meter airbag low entrance city bus.
