What does MG ECO mean?

ECO refers to the vehicle's economical driving mode function. ECO is an English abbreviation formed by combining 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 economical mode has been activated. Eco mode can be 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 merely serves 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 vehicles employ 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 enable 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 reflect the fuel-saving characteristics of Eco mode and could instead 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 system prioritizes speed, causing the Eco mode to deactivate automatically. 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 function under these conditions either.
The ECO button on MG cars is the fuel-saving mode switch. I particularly love using this feature when commuting in my MG HS—after pressing it, the system actively limits power output, lowers the shift RPM to around 2000, and adjusts the air conditioning to energy-saving mode. Real-world tests show it can save up to 15% on fuel costs in city driving, though acceleration does become noticeably sluggish. It's perfect for traffic jams, but remember to turn it off when in a hurry or on highways, otherwise you'll feel the lag even when flooring the throttle during overtaking.
