What does ECO on a vehicle mean?

ECO refers to the vehicle's economical driving mode, which is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard illuminates, it indicates that the vehicle's economical mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type has a dedicated button, allowing the driver to choose whether to enable it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard illuminates, it serves merely as a reminder function. The Eco mode automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most vehicles employ the active Eco driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can generally enable the Eco mode. However, it is unnecessary to activate Eco mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of Eco mode but also negatively impact the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the system prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine's computer prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function in such scenarios.
I saw a button labeled 'eco' in my car and didn't understand what it meant at first. Later, I searched on a forum and found out that 'eco' stands for economy mode. When activated, the car adjusts the engine and throttle response to make driving smoother, reducing sudden acceleration and braking, which helps lower fuel consumption. I often use eco mode when stuck in city traffic, and I've noticed the fuel gauge drops much slower. Normally, a full tank gets me 300 kilometers, but now it can go up to 350. However, it does reduce power, so you need to press the accelerator harder when climbing hills. If the car is too old or has other issues, the eco effect might not be noticeable. I recommend buying a new car with this feature—it's both eco-friendly and cost-effective, saving a lot on fuel expenses in the long run.
