Is the Buick Excelle fuel consumption high?
2 Answers
The average fuel consumption of the Buick Excelle is 8.4 liters per 100 kilometers, which is not considered high and falls into the medium range. Factors affecting fuel consumption: 1. Weight: The relationship between vehicle weight and fuel consumption is directly proportional. A 10% reduction in vehicle weight will correspondingly reduce fuel consumption by several percentage points. 2. Design: A smaller aerodynamic drag on the vehicle body will significantly reduce fuel consumption, and these two factors are also directly proportional. 3. Thermal efficiency: Strive to improve the engine's thermal efficiency. Generally, the thermal efficiency of gasoline engines (the proportion of fuel converted into useful work) reaches over 30%, while diesel engines exceed 40%. This is the main reason why diesel engines have lower fuel consumption than gasoline engines. The ratio of engine power to displacement is called the power per liter, indicating how much power the engine can generate per liter of displacement. The higher this ratio, the more advanced the engine technology. 4. Vehicle condition: Good vehicle condition is fundamental to fuel efficiency. Many drivers take great care of their vehicles, but due to a lack of automotive knowledge, their care is often limited to keeping the car clean, while other aspects are frequently neglected. In fact, scientific maintenance can help achieve fuel-saving goals. For example, wheel bearings should be lubricated regularly, but some owners are unaware of this until the bearings wear out. 5. Road conditions: Driving conditions are an important factor affecting fuel consumption. Every car has its own "economical speed," generally designed within the range of 70 to 90 kilometers per hour. If the car can move smoothly within this speed range in urban areas, the fuel consumption should be close to the test values obtained in standard test environments. When the car moves slower than a bicycle, fuel consumption increases significantly. 6. Driving habits: Incorrect driving habits can lead to a significant increase in fuel consumption. With the advent of the automobile era, there are more and more non-professional drivers, which inevitably leads to a major problem: incorrect driving habits result in higher vehicle fuel consumption. This impact is even greater on large-displacement vehicles.
The fuel consumption of the Excelle is generally not high. Official data shows about 6-7L/100km in city driving and around 5L on highways, which is quite fuel-efficient. However, actual consumption may vary depending on the driver. For example, when I drive the Excelle, I notice that aggressive driving or heavy traffic can increase fuel consumption to 8-9L. Factors affecting this include your driving habits: rapid acceleration and hard braking consume more fuel; and the condition of the car, such as underinflated tires or uncleaned engine carbon deposits, can also increase fuel consumption. It's recommended to check your tires weekly and maintain smooth driving to keep it mostly under 7L. On highways, the Excelle performs excellently, maintaining stable low consumption, making it a great choice for daily commuting.
