What is the ECON function of the Accord?

[OPeyton]

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: 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 is considered a normal operating mode for the car. In this mode, the throttle pedal response is more sensitive than in Eco mode. Sport mode: Sport mode can be used during aggressive driving. When activated, the throttle pedal response becomes very sensitive, and the transmission delays shifting. The transmission will only upshift once the engine reaches the redline. In Sport mode, the engine speed is maintained 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 enabled. Only when high torque output is required (e.g., climbing a slope) or when driving at very high speeds should ECON mode be turned off. After pressing the ECON button, the car enters a low-carbon, eco-friendly driving mode. The ECU, engine, and transmission then operate intelligently in the most fuel-efficient manner, 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 ECON mode is simple and effective, it does not work under certain conditions: When the speed exceeds 120 km/h, priority is given to maintaining speed, and the fuel-saving mode automatically deactivates. This means that if the car exceeds the economical speed range (typically between 60-90 km/h), ECON mode will not save fuel. The key to ECON mode is its reliance on computer-controlled operation while driving to be effective. Therefore, it does not work during idle parking or when the car is in N, P, or manual mode. When overcoming significant resistance or requiring high torque output (e.g., climbing a slope), the ECU prioritizes ensuring sufficient power to drive the car, and ECON mode will not function in such cases.

The Accord's ECON function is an energy-saving mode, which I frequently use while driving this car and find very practical. When the ECON button is activated, the throttle response becomes smoother and less sensitive, avoiding sudden acceleration that wastes fuel. At the same time, the air conditioning power automatically reduces, providing gentler airflow that is still comfortable enough, which helps save electricity and fuel consumption. In urban congested areas, such as waiting at red lights or in traffic jams, ECON controls engine output to reduce idling fuel consumption. Long-term use can help you save approximately 5% on fuel and also reduce exhaust emissions. Honda designed ECON to represent Ecology and Economy, embodying the concept of combining environmental protection and economy, making it ideal for daily commuting. However, during high-speed driving or acceleration for overtaking, you might feel the power is somewhat weaker, and it's better to turn it off in such situations. Overall, ECON enhances driving comfort, especially during peak traffic hours, making driving smoother and more economical.
