What is the ECO mode in a car?

ECO refers to the car's economical driving mode. 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 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 dashboard Eco indicator light turns on, 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 utilize 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 enable 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 could also 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 car 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 control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function in such scenarios.
When I drive with ECO mode on, the fuel consumption really drops significantly. This is the economy mode, meaning the vehicle system automatically optimizes settings to save fuel. When you activate it, the engine's output power is limited, the throttle response becomes softer, acceleration is not as aggressive, and the transmission shifts up earlier, allowing the car to operate in a more efficient state, reducing fuel consumption. The air conditioning also adjusts in ECO mode, with slightly reduced power, but the cooling effect is still decent. I clearly feel fewer refueling stops when driving in the city, with similar weekly commuting distances but able to stretch an extra few dozen kilometers. It feels a bit sluggish when climbing steep slopes or trying to overtake quickly, so it's best to turn off ECO in those situations. Over long-term use, the fuel bills have saved quite a bit, averaging a few liters less per 100 kilometers. This mode is great for commuters and also helps reduce emissions. Remember to maintain the engine oil and check the engine regularly so ECO mode can continue to work effectively.
