In urban congested traffic conditions, turning on ECO mode works best. In such scenarios, strong power output is not required, and the frequent stop-and-go driving leads to higher fuel consumption. Activating ECO mode not only reduces fuel consumption but also enhances driving comfort. There are a few situations where ECO mode is unnecessary: When driving at high speeds (up to 100km/h), even if ECO is turned on, the vehicle's computer will prioritize speed, causing the ECO mode to automatically deactivate. When high torque output is needed, such as when climbing hills, the engine control unit will prioritize ensuring sufficient power to drive the vehicle, and the ECO mode will automatically deactivate. Modes: Generally, ECO driving modes can be divided into two types: passive ECO driving mode and active ECO driving mode. The passive ECO driving mode primarily serves as a reminder and guidance function. The active ECO driving mode usually has a dedicated button; once activated, a series of driving-related settings will change. For example, the throttle opening corresponding to the same accelerator pedal depth becomes smaller (making the pedal less responsive), the transmission shift logic prioritizes fuel economy (shifting up earlier), and some vehicles may also adjust the air conditioning output power accordingly.
