When to Turn On ECO Mode?
2 Answers
It should be turned on in most cases. However, there are two situations where it is not recommended: When the vehicle speed is very high (reaching 100KM/h): During high-speed driving, the vehicle requires better power performance. At this time, the acceleration effect of ECO mode is not ideal, requiring deeper throttle input, which actually results in insignificant fuel-saving effects. Moreover, even if ECO is activated, the vehicle's computer will prioritize speed, causing the ECO mode to automatically deactivate. When high torque output is needed (e.g., climbing a slope): When high torque output is required, such as when climbing a slope, the engine computer will prioritize ensuring sufficient power to drive the vehicle, and the ECO mode will not function either. 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. The throttle pedal sensitivity decreases, and the transmission shifts up more aggressively. Comfort mode: This mode can be considered a normal operating mode for the car. In this mode, the throttle pedal response is more sensitive than in Eco mode. Sport mode: This mode can be used during aggressive driving. After activating Sport mode, the throttle pedal response becomes very sensitive, and the transmission delays shifting. The transmission will only upshift when the engine speed reaches the redline zone. After switching to Sport mode, the engine speed will remain around 3,000 RPM, ensuring better power response during acceleration. When the car enters ECON mode, it can achieve reduced fuel consumption and energy savings, but the vehicle's power will weaken. ECON can be understood as an abbreviation for "economy." In most cases, it is recommended to activate ECON mode, except when high torque output is needed (e.g., climbing a slope) or when the vehicle speed is very high, in which case ECON mode must be turned off. After pressing the ECON button, the car enters a 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 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.
I often drive to and from work, and when the city is jam-packed with traffic, ECO mode becomes my best friend. Turning it on makes the car more fuel-efficient, with a gentler throttle response, avoiding fuel wastage in stop-and-go traffic. I remember one summer during peak hours when I was stuck in a traffic jam; I turned on ECO mode and set the air conditioning to energy-saving mode, and the fuel gauge dropped much slower. By the end of the month, I saved quite a bit on fuel costs. It’s also suitable for urban roads when there’s no need for sudden acceleration, like when picking up the kids or grocery shopping—smooth driving while saving money. However, don’t use it on mountain roads or when overtaking, as the car will lack power and struggle uphill. Just make it a habit—it’s eco-friendly, reduces emissions, and even extends engine life.
