What does ECON mean on a car?

ECON is the switch for the car's fuel-saving mode, which can be turned on or off with this button. Modern cars generally offer three driving modes to choose from: fuel-saving mode, comfort mode, and sport mode. Below is information about these three modes: Fuel-saving mode: When the car is in this mode, fuel consumption is relatively low. The throttle pedal sensitivity decreases, and the transmission shifts up more aggressively. Comfort mode: This mode can be considered a standard operating mode for the car. In this mode, the throttle pedal response is more sensitive than in fuel-saving mode. Sport mode: This mode can be used for aggressive driving. When sport mode is activated, the throttle pedal response becomes very sensitive, and the transmission delays shifting. The transmission only upshifts 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 the car enters ECON mode, it achieves reduced fuel consumption and energy savings, but the car's power output is weakened. 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 required (such as when climbing a slope) 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 rapid upshifts and smooth acceleration. The air conditioning system also operates in an energy-saving state. When the driver presses the throttle pedal deeply, the ECON system effectively controls the opening and closing of the intake valves to ensure smooth engine operation and energy savings. Although the ECO 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 fuel-saving mode automatically deactivates. This means that if the speed exceeds the economical range (typically between 60-90 km/h), the ECO mode will not save fuel. The key to the ECO mode is its independent operation by the car's computer during driving. Therefore, it does not function during idle parking or when the car is in N, P, or manual mode. When overcoming significant resistance and requiring high torque output, such as when climbing a slope, the ECU prioritizes ensuring sufficient power to drive the car, and the ECO mode will not work in such cases.
My friend who drives a Honda told me that ECON stands for Economy Mode. Pressing this button makes the car feel like it has a different personality. The engine response becomes a bit sluggish, the air conditioning isn’t as aggressive, and even the transmission deliberately holds gears longer. Last time I tried it in a CR-V, when starting from a red light, I had to press the accelerator halfway before the car slowly moved forward. But it really does save fuel—using this mode for city commuting can drop the displayed fuel consumption by more than half a liter. Just remember not to use it on the highway, or you’ll struggle with power when overtaking, which can be frustrating. Also, turn it off on rainy days, as the weak power output can make the car prone to skidding.
