1. Large capacity:
Owing to its reasonable interior layout design, Huanghai 11.5-meters long hybrid bus has a wheelbase of 5,880mm, and its bearing capacity is close to that of a 12-meters long bus.

2. High safety
The power battery, control chamber, LNG storage device and passenger compartment are all separated from each other.

3. Easy to disassemble and maintain
Controllers are arranged in the centralized mode but are placed in separate chambers.

4. Strong resistance to impact and water
Power battery is mounted on top of the vehicle, and LNG is placed in the rear chamber, with a ground clearance of more than 1980mm.

5. Excellent corrosion resistance
The vehicle adopts cathodic electrophoresis technology.

6. Great comfort
Leaf spring is designed with a rubber bushing structure.

7. Reasonable distribution of axle load
The hybrid city bus operates with good stability and uniform tire abrasion.

8. Small turning diameter
The front overhang and wheelbase of the vehicle have been optimized, which results in a highly flexible steering performance.

9. Great bearing capacity
The front axle of the vehicle can withstand loads of 6.5 tons, and the rear axle has a bearing capacity of 13 tons. The maximum total mass can reach up to 18 tons.

10. Battery is separated from gas cylinder.
The adoption of 3-in-1 ATS cooling system ensures an increased space for maintenance of engines and attachments.

11. Lightweight design
The self-supporting technology for welding of small rectangular tubes allows for the effective use of every steel section of the vehicle. The vehicle body is lightweight, energy-saving and environmentally-friendly.

12. Domestic leading new energy system
a. Standard configurations include automatic clutch and 4-speed dual-intermediate-shaft AMT gearbox, which makes this vehicle run more stably and safely.
b. Equipped with dual motor and 4-speed transmission, this vehicle can receive sufficient power in the event of rapid acceleration or uphill. It efficiently recycles energy in case of rapid deceleration or downhill.
c. With 10 years' experience in hybrid power control strategy and alignment, Huanghai research institute can make sure every part of the system maximizes its efficiency, thereby keeping the system in optimum working condition.
