Since 2021, the Hycet plant has been producing the 3.0-liter Great Wall GW6Z30 V6 engine, which is only found in the company’s biggest models, like the Tank 500 SUV and the Pao pickup truck. Dual turbocharging and combined fuel injection set the unit apart.
The GW4N20, GWE20CB, and GW6Z30 are Hycet motors from the second generation.

Disadvantages of the GW6Z30 engine
The motor had numerous issues during its first year of production, but the majority have since been resolved.
Uneven reaction to the gas pedal is currently the primary source of complaints on the network.
Although several flashes have already been released, power outages continue to happen.
The engine is protected from carbon buildup on the valves by the combined injection system.
