What is the ECO mode in cars?

ECO refers to the car's economical driving mode function. ECO is an English abbreviation formed by 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 its own 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. 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 system 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 cars adopt the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can generally activate the Eco mode. However, it is unnecessary to activate Eco mode when the speed exceeds 120 km/h, during idling, 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 affect 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 car prioritizes speed, causing the Eco mode to automatically deactivate. During idling 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 operate in such scenarios.
I drive to work every day and love using ECO mode during traffic jams. It's an economical driving mode - just press a button to activate it. The throttle response becomes slightly slower, making acceleration feel less aggressive, but the trade-off is better fuel efficiency. The system automatically adjusts transmission logic, such as shifting gears earlier to reduce engine load, and even slightly lowers air conditioning power. During heavy traffic, I've observed about 15% fuel savings, which translates to hundreds of dollars in monthly fuel cost savings over time. Note: It's best to deactivate ECO and switch back to normal mode when driving on highways or needing quick overtaking maneuvers, as the delayed response might feel uncomfortable. ECO is perfect for stop-and-go city driving and can even extend maintenance intervals since the engine operates more smoothly.
