What does ECO mean?

ECO refers to the economic driving mode of a car. It is an English abbreviation derived 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 means the vehicle's economy mode has been activated. Eco mode can be either active or non-active. The difference lies in the fact that the active mode 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. Non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard illuminates, it serves only 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 use the active Eco driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can 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. Doing so may 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 km/h, the car prioritizes speed, and the Eco mode automatically deactivates. During idle parking, in N/P gear, or in 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.
ECO in cars typically refers to the economy mode, which is an energy-saving driving state. Having driven for so many years, I habitually use this function as it significantly saves fuel and money. When ECO is activated, the engine's output power is reduced, such as slower throttle response and earlier gear shifts by the transmission to avoid high fuel consumption during acceleration. I always keep it on during city commutes and found that a full tank can last about 50 kilometers more, saving around a hundred yuan in fuel costs per month. Although the acceleration is slightly softer and not suitable for emergency overtaking, this mode makes stop-and-start driving smoother and reduces wear. Additionally, it cuts carbon emissions, making it environmentally friendly, and is a must-have feature in modern cars. I recommend checking for ECO when buying a new car and pairing it with regular maintenance like oil changes to maintain its effectiveness, overall enhancing driving economy.
