Where is the engine of the Great Wall VV7 produced?

The engine of the Great Wall VV7 is independently developed by Great Wall Motors and is a domestically produced engine. The engine model of the Great Wall VV7 is 4C20A, with a maximum power of 172KW, a maximum torque of 360Nm, and a maximum horsepower of 234. For daily maintenance of the Great Wall VV7's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to the mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, its performance will degrade, leading to various engine problems. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
I've driven the Great Wall VV7, which uses an engine developed by Great Wall themselves, produced at their factory in Baoding, Hebei, China. That was a 2.0T turbocharged engine, delivering strong and smooth power with quick acceleration and hardly any jerking. When I bought the car, the salesperson introduced it as domestically made without any imported parts. After driving it for over a year, it's been quite reliable with no major issues. It's fuel-efficient for daily driving and performs well on highways. I feel Great Wall has put effort into their engines, and the quality has improved significantly compared to ten years ago. Domestic cars are now truly competitive, offering much better value for money with their self-developed engines. Maintenance is also convenient, just find a local repair shop. Overall, the origin of the engine proves the progress of Chinese manufacturing.
I used to pay close attention to automotive details and knew that the Great Wall VV7's engine was manufactured in-house at their factory in Baoding, Hebei. The engine is a 2.0T turbocharged model, with technology developed by Great Wall's own team. I've seen quite a few during repairs, and the assembly precision is quite good, with strong durability. After driving it for two or three years, the engine rarely had any issues. I learned that Great Wall has invested heavily in self-research for engines to avoid reliance on foreign technology. This engine delivers stable power output, is fuel-efficient in urban conditions, and provides a comfortable daily driving experience. Consumers now trust domestic brands more because localized production makes maintenance and repairs quicker. I believe the progress of domestic engines makes car purchases more affordable and driving much more reassuring.
