Product advantages

Economy

  • Minimum fuel consumption is 198g/kW•h, which is (3-4)g/kW•h lower than that of competing products, ensuring a wider economic speed range; the standard two-speed electromagnetic fan can save 3% more fuel than the traditional rigid fan, ensuring a low accessory power consumption.
  • Power performance

  • High torque (output power at medium/low speed range increased), strong power, and excellent starting acceleration performance.
  • Reliability

  • The brand-new design is adopted, and B10 life is 500,000 km; the engine is designed and developed according to the large-displacement engine concept, and such important parts as turbocharger, starter and fuel system from excellent global suppliers are used to guarantee the reliability of key parts.
  • Comfort

  • NVH is better than that of competing products, and outdoor noise in acceleration is 4dB(A) lower than that of competing products; the standard secondary balance mechanism reduces the vibration severity significantly. 
  • Adaptability

  • The vehicle can be equipped with various accessories such as alternator, power steering pump, A/C compressor, and air compressor, enriching the user's choices.
