What does ECO mean on a car?

ECO refers to the car's economical driving mode function. ECO is an English abbreviation formed from the words Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active eco driving mode and passive eco driving mode. When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economy mode has been activated. ECO mode is categorized into active and passive types. The difference lies in the fact that the active type has a dedicated button, allowing the driver to choose whether to activate 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 passive ECO mode does not have a dedicated button. When the dashboard ECO indicator light turns on, it serves merely as a reminder. The ECO system automatically evaluates driving behavior, and if the current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most cars use the active ECO driving mode, which means they have a dedicated switch button. Therefore, during daily driving, the ECO mode can be activated. However, it is unnecessary to activate the 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, as it does not reflect the fuel-saving characteristics of the ECO mode. Additionally, the ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, and the ECO mode automatically deactivates. 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 control unit prioritizes ensuring sufficient power to drive the vehicle, and the ECO mode will not function in such cases.
When I first bought my car, I also wondered what ECO was. Later, I learned that it's the fuel-saving mode. After activation, the car adjusts the working state of the engine and transmission, such as slowing down the throttle response, shifting gears earlier, and avoiding high-speed operation as much as possible. The air conditioning will also automatically switch to low power mode, all to save fuel. However, you might feel that the acceleration isn't as fast, especially when going uphill or trying to overtake. I think using ECO is most cost-effective in city traffic jams, but it's not very effective on highways. Also, it's safer to turn it off when the road is wet. Long-term use doesn't harm the car and can save some fuel costs.
