Super power

High torque at low speed, the maximum torque is reached at 1000rpm, the power is surging, and you can do whatever you want. Optimized and calibrated low-speed and medium-speed external characteristics and transient response, the vehicle starts more quickly and has a more sensitive response.


Energy efficient

A new generation of BOSCH electronic control system, high squeezing flow equivalent combustion technology, high mixing uniformity ventilation technology, and high-efficiency electronically controlled pressurized air intake technology, save 2-3 kilograms of gas consumption per 100 kilometers compared to competing products, and save 100,000 kilometers per year 14,000 yuan.


Extra long oil change

The 60,000-kilometer-long oil change has been comprehensively upgraded to reduce maintenance frequency and improve attendance.


Reliable and durable

High-strength steel pistons, super-wear-resistant steel crankshafts and special natural gas piston rings ensure longer engine life and more money.
