High reliability
- Frame block, dry cylinder liner, high engine reinforcement, over 45,000 hours of bench test cumulatively, and over 50 million kilometers of whole vehicle road test
Excellent NVH performance
- Idle noise 81dB(A) - the body is drum-shaped skirt design, with high body strength and low vibration, which greatly reduces noise
- Rear gear chamber, high precision gear is used to shear gear, which provides stable operation and further reduces mechanical noise
- Multiple injection technology to reduce combustion noise significantly
Ultra-low fuel consumption
- The lowest fuel consumption rate of 183g/(kW·h) is achieved by optimizing combustion, improving camshaft profile, and high efficiency supercharger, using multiple high efficiency components. The low-speed fuel consumption area covers the usual conditions of 1000-1400r/min, making it more economical and fuel-efficient
Powerful
- Maximum torque 2110N·m for superior acceleration
- A smaller rear axle ratio can be selected for power, up to 120km/h
Altitude capability
- Underated power at 3500m altitude and less than 5% power loss at 4100m rated speed for extreme environmental suitability
