Is the engine of the Hongqi H9 from Audi?
2 Answers
The engine brand of the Hongqi H9 is not from Audi; it is independently developed by China FAW. China FAW Group Co., Ltd. is currently one of the largest automotive enterprise groups in China and a state-owned large-scale automobile manufacturer directly under the central government. The engine model used in the Hongqi H9 is the CA4GC20TD-31, with a maximum horsepower of 252 HP, a maximum power of 185 KW, a maximum power speed of 5500 rpm, and a peak torque of 380 Nm. For daily maintenance of the Hongqi H9's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine issues. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and bring contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. 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. Small amounts remain suspended in the oil, while larger amounts precipitate, 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.
To be honest, I've been closely following automotive technology, and the engine of the Hongqi H9 is definitely not from Audi. It's a product of Hongqi's independent research and development. Hongqi has a dedicated R&D center in Changchun, and the 2.0T and 3.0T turbocharging technologies used are entirely Chinese-designed. I've had the chance to drive this car, and the engine responds quickly with smooth output. It feels excellently handled in terms of noise reduction and fuel efficiency. From its early days of imitating American models to now achieving full independence, Hongqi has demonstrated remarkable progress. While Audi engines are also good, Hongqi's are more adapted to Chinese road conditions and simpler to maintain. I think this is something to be proud of—domestic brands finally have their own high-end technology, and the engine's reliability gives me great confidence when driving.
