What is the eco on the Buick Excelle?

[LeBentley]

The eco on the Buick Excelle is the vehicle's economical driving mode. During driving, the eco mode comprehensively evaluates and analyzes factors affecting fuel consumption, such as automatic transmission gear, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal fuel quantity to supply the engine, effectively reducing fuel consumption compared to normal driving mode. The Buick Excelle is a premium mid-size car launched by SAIC-GM, featuring the new Buick family-style wing grille that interlocks with LED headlights to form a visual focal point, highlighting a sense of technology and refined value. In terms of body dimensions, the car measures 4419mm in length, 1814mm in width, and 1487mm in height, with a wheelbase of 2685mm.

The ECO mode on the Buick Excelle is essentially a fuel-saving feature. When activated, the car actively helps you save fuel. It primarily works by limiting throttle response and adjusting air conditioning power to reduce fuel consumption. For example, pressing the accelerator will result in smoother acceleration without sudden bursts of speed, and the air conditioning cooling will be gentler, consuming less electricity. Based on my real-world testing in the city with the Excelle, activating ECO mode can save about 1 liter of fuel per 100 kilometers, which is especially useful during peak traffic hours in the morning and evening. However, I rarely use it on highways since the restricted power makes overtaking less effective. Before long trips, I also make sure to check the tire pressure, as underinflated tires can also impact fuel efficiency. It's recommended to check tire pressure every three months to maximize the effectiveness of ECO mode.

I use ECO mode every day, and it's quite worry-free. Essentially, it puts the car into an economical state where the system automatically adjusts throttle depth, transmission logic, etc. For example, pressing the accelerator with the same force results in gentler engine output. After using it, I clearly feel the car drives more smoothly, starts more calmly in traffic jams, and the AC cooling is gentler and less power-consuming. Actual tests show urban fuel consumption can drop by 8%-10%, saving dozens of yuan on gas each month. The only thing to note is that it's best to turn off ECO on uphill sections to avoid insufficient power. Keeping it on long-term can also reduce carbon buildup, which is good for engine maintenance.

The ECO mode in the Excelle primarily reduces throttle sensitivity and air conditioning power. When activated, a green ECO light will illuminate on the lower left side of the steering wheel, indicating slower throttle response and smoother engine RPM control. The benefit is noticeable fuel savings for city commuting, reducing weekly gas station visits. However, driving above 120km/h on highways makes acceleration feel sluggish, often requiring manual deactivation for overtaking. Occasionally, it may conflict with the auto start-stop function, leading to increased fuel consumption during traffic jams due to frequent engine restarts—in such cases, using only ECO mode is advisable.

The ECO button is located on the left side of the steering wheel. When activated, the vehicle automatically enters an energy-saving mode. Its core function is to limit sudden acceleration and reduce air conditioning output, thereby lowering overall energy consumption. Based on usage, fuel consumption typically drops from 8L to 7.2L per 100 kilometers, with the most noticeable effect when running the air conditioning at maximum in summer. I observed that the transmission shifts up more proactively, keeping the engine within the economical 1500-2000 rpm range. However, it's advisable to avoid using this mode during rainy or slippery road conditions, as delayed throttle response may cause wheel spin. New owners are recommended to combine it with smooth driving habits—avoid hard braking or flooring the accelerator—to maximize fuel savings.

The Buick Excelle ECO actually optimizes three aspects: First, the throttle sensitivity is reduced by about 20%, making it feel like there's a cushion when pressing down; second, the air conditioning cooling power is automatically lowered by 30%, but the airflow remains unchanged; third, the transmission shifts up earlier to maintain low RPM operation. This setup can save over thirty yuan in fuel costs per month for city driving, making it particularly suitable for school runs or grocery shopping. However, the power is noticeably insufficient on mountain roads, and climbing steep slopes can feel sluggish—this is when you should turn it off. I recommend not rushing to use ECO during the break-in period for new cars; waiting until the engine fully adapts will yield better results.
