Why is the fuel consumption of Hongqi H5 high?
3 Answers
Hongqi H5 has a combined fuel consumption of 6.2-6.4L/100km. Currently, there are 6 models of Hongqi H5 available for sale: the DCT Qiyue Edition and DCT Qiyun Edition, with a combined fuel consumption of 6.2L/100km. The Automatic Zhilian Qiyun Edition, Automatic Zhilian Qichang Edition, Automatic Zhilian Qiling Edition, and Automatic Zhilian Qixiang Edition have a combined fuel consumption of 6.4L/100km. The above figures are the NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, around 8.0L. Specific factors affecting car fuel consumption are as follows: Car weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L engine and a weight of about 1.2 tons has a fuel consumption of approximately 7.5 liters (calculated under full load), while an SUV weighing about 1.5 tons has a fuel consumption of about 8.5 liters. Different weights result in varying fuel consumption. Drag coefficient: Higher drag increases fuel consumption during driving. Cars with better aerodynamics have lower drag, leading to lower fuel consumption. Economical RPM: During driving, the engine has an optimal torque output point where fuel consumption is minimized. Generally, small-displacement cars reach this point at around 70 km/h, while larger-displacement cars achieve it at about 100 km/h. Maintaining speed within this economical RPM range results in the least fuel consumption. Driving style: Aggressive driving behaviors such as rapid acceleration, frequent overtaking, and not easing off the throttle before red lights can increase fuel consumption.
I've been driving the Hongqi H5 for several years and found that high fuel consumption is quite common, mainly due to the vehicle's inherent design. As a domestic luxury car, the Hongqi H5 has a substantial curb weight, with solid materials that add to the burden. Although the engine delivers ample power, its optimization is lacking, especially during initial acceleration, which consumes more fuel. Additionally, the transmission isn't the most responsive, leading to higher fuel consumption in stop-and-go city traffic. I've also noticed that the aerodynamic design is average, with significant wind resistance at high speeds further increasing fuel consumption. Over the long term, regular maintenance is essential—changing the air filter and spark plugs periodically is crucial. In summary, this isn't a major issue; driving more on highways and practicing smooth driving can help improve fuel efficiency and save some money on gas.
I commute with a Hongqi H5, stuck in city traffic every day, and the fuel consumption often soars into double digits. My experience is that driving habits play a major role. With many traffic lights, frequent hard acceleration leads to slow vehicle response, burning more fuel. Plus, the AC is always on, especially in summer when the cold air increases engine load. Frequent idling during stop-and-go also wastes fuel. Try adjusting your driving style, like maintaining an economical speed around 60 km/h, easing off the throttle early, and braking less. The H5 in the Hongqi lineup is positioned for comfort, so slightly higher fuel consumption is understandable. Paying attention to proper tire pressure can help a lot.
