What is the actual fuel consumption of the Hongqi HS7?
2 Answers
The comprehensive fuel consumption of the Hongqi HS7 is 8.6-10.9L/100km. Currently, there are 12 models of the Hongqi HS7 on sale. The two-wheel-drive Zhilian Qixiang seven-seater, two-wheel-drive Zhilian Qichang five-seater, two-wheel-drive Zhilian Qichang seven-seater, two-wheel-drive Zhilian Qixiang five-seater, and two-wheel-drive Zhilian Qiyue five-seater models have a comprehensive fuel consumption of 8.6L/100km. The four-wheel-drive Zhilian Qiyue five-seater, four-wheel-drive Zhilian Qixiang five-seater, four-wheel-drive Zhilian Qichang five-seater, four-wheel-drive Zhilian Qiling five-seater, four-wheel-drive Zhilian Qixiang seven-seater, four-wheel-drive Zhilian Qichang seven-seater, and four-wheel-drive Zhilian Qiling seven-seater models have a comprehensive fuel consumption of 10.9L/100km. The above figures are NEDC comprehensive fuel consumption, which are the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than these values, ranging from 6.8-14.2L/100km. Methods to reduce fuel consumption: Clean engine carbon deposits: Excessive engine carbon deposits are a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not obvious, it indicates a large amount of carbon deposits in the engine. In this case, the car must be taken to a 4S shop for professional cleaning of the engine carbon deposits by technicians. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio of the engine. Once damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gas during driving, and the oxygen sensor should be replaced at this time. Regularly replace the three filters: During the use of the vehicle, the oil filter, air filter, and fuel filter must be replaced regularly. If not replaced for a long time, they become dirty and send incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits. Check the electronic control unit: Although the reliability of the engine's electronic control unit is very high, in older vehicles, various faults are inevitable.
I've been driving the Hongqi HS7 for almost two years now, mainly for daily city commuting. During heavy traffic in urban areas, the fuel consumption can reach around 13L, and during peak hours, it even goes up to 14L. On weekends when driving on highways, it gets better, usually dropping to the range of 8-9L. Overall, an average of 11-13L/100km is quite common. This car is big and heavy, so starting up consumes a lot of fuel. That's why I always advise my friends to use cruise control more often to save some money. Also, remember to maintain it regularly—change the engine oil frequently and don't delay, keep the tire pressure at the standard value. It's not surprising to see an extra liter or two of fuel consumption when using air conditioning in winter or summer. Overall, I feel it's worth it—the space and safety features are luxurious, and the higher fuel consumption is a trade-off you have to accept. I've calculated the fuel costs myself; spending a few hundred yuan more on commuting each month is just like paying for comfort. But for long-distance road trips, be prepared with a bigger budget for fuel.
