The fuel consumption of the Buick Excelle 1.5T automatic transmission is 7-9L per 100 kilometers. The fuel consumption of a vehicle mainly depends on the driving habits of the driver and the quality of the driving conditions. As long as the vehicle is used normally and maintained on schedule, it should perform well. If the fuel consumption is too high, it may be necessary to clean the carbon deposits from the engine. Below are the factors related to 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 otherwise identical conditions, an engine with a larger cylinder volume (displacement) will naturally consume more fuel. 2. Fuel consumption and RPM: During normal driving, the RPM range is usually between 1,100 and 3,000 RPM. The maximum RPM of a typical family car does not exceed around 6,000 RPM. In racing conditions, maintaining RPM at twice the limit of a family car (over 10,000 RPM) will naturally result 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 and directly increases fuel consumption. Additionally, some car owners install spoilers and body kits, which undoubtedly increase the car's aerodynamic drag. At low speeds, spoilers have no effect and only add driving resistance, increasing the overall load on the vehicle, which inevitably leads to higher fuel consumption.

I've been driving the Buick Excelle 2021 1.5L automatic version for over a year. The official combined fuel consumption is around 6.5 L/100km, but it fluctuates significantly in real-world driving. During city commuting in traffic jams, it can reach 7.5-8.5 liters, while highway driving on weekends easily stays between 5.5-6 liters. I've tested that using air conditioning adds about 1 liter, and low tire pressure also increases fuel consumption. Comparatively, Japanese counterparts like the Toyota Corolla might be 0.5 liters lower, but this car offers quicker power response and more spacious interiors, making the fuel consumption acceptable for me. Overall, the daily average is 6.8 liters per 100km. With a 52-liter fuel tank, a full tank can cover over 700 km, which is quite practical. The key is that maintaining steady driving habits can optimize fuel efficiency.

As a daily commuter, my 2021 Buick Excelle 1.5L automatic averages around 6.7 L/100km fuel consumption. In city traffic during rush hour, it can spike to 8L, but drops below 6L on highways or national roads. A full tank costs about 330 RMB and easily covers 500+ km. A friend with the same model reports similar mileage, though frequent AC use and hard braking adds about 1L. Compared to last year's older version, the 2021 model's engine upgrades improved fuel efficiency slightly. Considering affordable maintenance, good sound insulation, and overall practicality, the marginally higher consumption isn't a dealbreaker—driving smoothly compensates well.

Fuel consumption largely depends on your driving habits. The official combined fuel economy for this 2021 Buick Excelle 1.5L automatic is 6.5L/100km, but real-world figures typically fluctuate between 6-8L. If you frequently accelerate aggressively or drive in congested urban areas, consumption can quickly exceed 7L/100km. Conversely, gentle and steady driving can bring highway consumption below 6L. Running the air conditioning at full blast adds about 1L, while winter/snowy conditions increase consumption further. Maintaining proper tire pressure and regular oil changes help control fuel usage. Overall, it delivers average efficiency - neither the most frugal nor wasteful, with driving style being the decisive factor.
