What is the ECO mode in automatic transmission cars?

ECO refers to the car's economic 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 economic 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 illuminates, 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 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 cars employ the active eco driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can generally activate 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. In these scenarios, activating eco mode would not demonstrate its economic fuel-saving characteristics and could instead impact the vehicle's power performance. Additionally, the eco mode typically becomes ineffective under the following conditions: 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 hills, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the eco mode will similarly not function.
I always prefer to set my car to ECO mode because it's an intelligent energy-saving setting. In automatic transmission vehicles, ECO stands for Economy Mode, which reduces fuel consumption by optimizing engine power output and transmission shift strategies. Simply put, it means slower throttle response when you press the accelerator, with gear shifts favoring higher gears to maintain lower RPMs and reduce fuel usage. I use it most often when driving in the city, saving quite a bit on fuel—my average fuel consumption drops from around 10 liters to about 8 liters per 100 km, which is really cost-effective. However, the power is slightly weaker when climbing hills, so I switch to other modes to avoid engine strain on steep roads. This smart control also involves adjusting the air conditioning system to minimize unnecessary energy waste. Overall, ECO mode is great for daily commuting, saving costs, and being eco-friendly. If the car is well-maintained, ECO mode can perform at its best.
