Does the 2021 X-Trail save fuel with ECO mode on?

[OJosephine]

ECO mode primarily makes comprehensive judgments and analyses during vehicle movement regarding factors that affect fuel consumption, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit then calculates the optimal fuel quantity to supply the engine for operation, effectively reducing fuel consumption compared to normal driving mode. Simply put, it controls the engine speed with appropriate gear positions to minimize unnecessary fuel consumption. There are a few situations where it's unnecessary to activate ECO mode: When the car is 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 computer will prioritize ensuring sufficient power to drive the vehicle, causing the ECO mode to automatically deactivate. Modes: Generally, it can be divided into two types: passive ECO driving mode and active ECO driving mode. The passive ECO driving mode mainly serves as a reminder and guidance function. The active ECO driving mode usually has a button; when activated, a series of driving-related settings will change, such as a smaller throttle opening corresponding to the same accelerator pedal depth (making the throttle less responsive), transmission shift logic more focused on economy (shifting up earlier), and some vehicles will also adjust the air conditioning output power simultaneously.
