Can the ECO mode be kept on all the time?

[McFinn]

The ECON mode in a car can be kept on continuously. It is the vehicle's energy-saving mode, and this button can turn the energy-saving mode on or off. Modern cars generally offer three driving modes to choose from: Eco mode, Comfort mode, and Sport mode. Below is information about these three modes: Eco mode: When the car is in this mode, fuel consumption is relatively low. In this state, the sensitivity of the accelerator pedal decreases, and the transmission shifts up more aggressively. Comfort mode: This mode can be considered a normal operating mode for the car. When in this mode, the accelerator pedal response is more sensitive than in Eco mode. Sport mode: Sport mode can be used during aggressive driving. After activating Sport mode, the accelerator pedal response becomes very sensitive, and the transmission delays shifting. The transmission only shifts up when the engine speed reaches the redline. After switching to Sport mode, the engine speed is maintained at around 3,000 RPM, ensuring better power response during acceleration. When a car enters ECON mode, it can achieve reduced fuel consumption and energy savings, but the vehicle's power output will be weaker. ECON can be understood as an abbreviation for 'economy.' In most cases, it is recommended to keep ECON mode on. Only when high torque output is needed (such as when climbing a hill) or when driving at very high speeds should ECON mode be turned off. Pressing the ECON button activates the low-carbon, eco-friendly driving mode. Subsequently, the ECU, engine, and transmission intelligently execute the driver's intentions in the most fuel-efficient manner, achieving optimal fuel economy through quick upshifts and smooth acceleration. When the driver presses the accelerator pedal deeply, the ECON system effectively controls the opening and closing of the intake valves to ensure smooth engine operation and energy savings. Although ECON mode is simple and effective to operate, it may not function under certain conditions: When the vehicle speed exceeds 120 km/h, priority is given to speed, and the energy-saving mode automatically deactivates. This means that if the speed exceeds the economical range (typically between 60-90 km/h), the ECON mode will not save fuel. The key to ECON mode is its operation via the car's computer during driving to ensure effectiveness. Therefore, it does not work when the car is idling, parked, or in N, P, or manual mode.
