Is the Dongfeng Fengguang 500 Fuel-Consuming?
2 Answers
The Dongfeng Fengguang 500 has a fuel consumption of 6-8L per 100 kilometers. The fuel consumption per 100 kilometers refers to the amount of fuel consumed by a vehicle driving at a certain speed for 100 kilometers on the road, which is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is measured under objective conditions by a dynamometer installed on the vehicle's chassis, converting the measured values into speed parameters, and then calculating the theoretical experimental fuel consumption data for the vehicle model at specified speeds. Below are the corresponding relationships of vehicle fuel consumption: 1. Fuel consumption and displacement: Fuel consumption is closely related to displacement, but this relationship is not absolute. A larger cylinder volume (displacement) can accommodate more combustible mixture (air-fuel), so under other identical conditions, an engine with a larger cylinder volume (displacement) will naturally consume more fuel; 2. Fuel consumption and engine speed: During normal driving, the engine speed range is mostly between 1000-3000 RPM, and the maximum speed of an ordinary family car usually does not exceed around 6000 RPM. During racing competitions, the engine speed is maintained at twice the limit of a family car (tens of thousands of RPM), which naturally results in very high fuel consumption; 3. Fuel consumption and vehicle modifications: Widening and enlarging tires increases the friction of the tires, which is equivalent to increasing the load on the car, thereby directly increasing the car's fuel consumption. At the same time, some car owners modify their cars with additions like spoilers and body kits, which undoubtedly increase the car's wind resistance. At low speeds, the spoiler does not function effectively and only adds driving resistance, increasing the overall load of the car, which inevitably leads to higher fuel consumption.
From my actual experience driving the Dongfeng Fengguang 500 over the past few years, its fuel consumption is generally acceptable but depends on how you drive. In heavy city traffic with frequent stops and starts, the fuel consumption can rise to around 10L/100km, which feels a bit high. However, when driving steadily on the highway, it can drop to 7-8L/100km, which is quite economical. My key takeaways for saving fuel are: maintaining proper tire pressure, avoiding overloading, and gentle throttle application, which significantly reduces fuel consumption. Additionally, I’ve found the 1.5L engine in this model to be quite efficient—using quality engine oil and replacing the air filter during maintenance can also optimize fuel efficiency. I usually track refueling data via an app, and on average, a full tank can cover just over 500km. While not the most fuel-efficient, it’s reasonable and holds an advantage over similar SUVs like the Haval H6. After two years of driving this car, I’m generally satisfied, though long-distance driving still requires attention to fuel-saving techniques.
