What does the vehicle ECON mode mean?

[DiEthan]

ECON is the abbreviation for the low-carbon and eco-friendly driving mode. This button can turn the energy-saving mode on or off. Modern vehicles 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 vehicle 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 is considered a normal operating mode for the vehicle. 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 highly sensitive, and the transmission delays upshifting. The transmission will only upshift once 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 vehicle enters ECON mode, it achieves reduced fuel consumption and energy savings, but the power output is weakened. ECON can be understood as the abbreviation for 'economy.' In most situations, it is recommended to keep ECON mode enabled. It should only be turned off when high torque output is required (e.g., climbing hills) or when driving at very high speeds. After pressing the ECON button, the vehicle enters the low-carbon and eco-friendly driving mode. Subsequently, the ECU, engine, and transmission operate intelligently in the most fuel-efficient mode to execute the driver's intentions, achieving optimal fuel economy through quick upshifts and smooth acceleration. 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 ECON mode is simple and effective to operate, it cannot function under certain conditions: When the vehicle speed exceeds 120 km/h, priority is given to speed, and the Eco mode automatically deactivates. This means that if the vehicle exceeds the economical speed range (typically between 60-90 km/h), the ECON mode will not save fuel. The key to the ECON mode is its reliance on computer-controlled independent operation while driving. Therefore, it does not work during idle parking, or when the vehicle is in N, P, or manual mode. When overcoming significant resistance and requiring high torque output, such as when climbing a hill, the ECU prioritizes ensuring sufficient power to drive the vehicle, and the ECON mode will not function in such cases.

ECON mode is the economy mode in a car, primarily designed for fuel efficiency. It reduces the engine's power output and adjusts the transmission's shift points, making the car accelerate more gently and feel smoother. Additionally, the air conditioning system is adjusted—for example, airflow is reduced, and cooling is less aggressive. Having driven many car models myself, I've found that with ECON mode enabled, a full tank of gas can last dozens of kilometers longer, especially useful for long-distance driving or city traffic jams. However, the downside is that the car might respond slower when overtaking due to reduced power. Overall, it's a great feature but should be used according to road conditions—for instance, using it on highways might reduce driving enjoyment. For daily commutes, I always keep it on—it saves money and is eco-friendly.
