Why is the Dongfeng Yixuan's fuel consumption so high?

1. To calculate how much a car costs per kilometer, you first need to know its fuel consumption. Divide the car's fuel consumption per 100 kilometers by 100 to get the fuel consumption per kilometer. Then multiply this figure by the price of gasoline to determine the fuel cost per kilometer. 2. For example, if a car consumes 6 liters per 100 kilometers and the price of 92-octane gasoline in Guangdong is 6.76 yuan per liter, the fuel cost for 100 kilometers (6 liters x 6.76 yuan/liter) would be approximately 40.56 yuan. Dividing 40.56 yuan by 100 kilometers and rounding off gives 0.41 yuan, meaning the fuel cost per kilometer is about 41 cents. 3. A car's fuel consumption is influenced by many factors, including driving conditions and habits. Examples include prolonged engine idling, sudden braking, inconsistent speeds, underinflated tires, aggressive acceleration, and long-distance driving at high speeds in low gears. Additionally, road conditions significantly affect fuel consumption, especially in urban traffic where congestion is common.

When driving my Dongfeng Yixuan, I noticed high fuel consumption, mainly due to my driving habits—I usually drive aggressively, with frequent rapid acceleration and hard braking, which is particularly noticeable in congested urban areas where the fuel consumption spikes as soon as I step on the gas. Additionally, often using the air conditioning and traveling with a full load increases the car's weight, naturally leading to higher fuel consumption. I recommend trying smoother driving and avoiding frequent stops and starts, which can save a lot on fuel. Moreover, the Dongfeng Yixuan is designed to be economical and practical, not a high-end version, so it tends to consume more fuel in city driving. I found that switching to lighter tires and reducing the load also helps. Maintaining good habits is key.

As a car owner, I believe high fuel consumption may stem from inadequate vehicle maintenance. For example, with my Dongfeng Yixuan, when the air filter accumulates dust over time, causing restricted engine airflow, fuel consumption increases; low tire pressure increases friction, making the car thirstier. Additionally, aged engine oil and spark plug issues can also reduce engine efficiency. Regular maintenance helps – I check the filters and tire pressure every 5,000 kilometers with good results. The Dongfeng Yixuan is generally durable, but maintenance must keep up, otherwise fuel consumption becomes noticeably higher during frequent short city trips. I recommend keeping maintenance records and not overlooking small details.

From a technical perspective, the relatively high fuel consumption of the Dongfeng Yixuan may be related to its engine design. It uses a small-displacement engine, which is suitable for urban driving but not highly efficient; coupled with the impact of body weight and drag coefficient, it struggles with power during high-speed driving or climbing, naturally leading to higher fuel consumption. Transmission matching also plays a crucial role—if the tuning is not optimal, difficult starts will consume more fuel. With years of experience in understanding automotive structures, I recommend opting for optimized later versions or improved software updates to enhance efficiency. Keeping the engine clean is a key strategy.
