What does the ECON button mean on a Beijing Hyundai car?

[VanOscar]

ECON is the abbreviation for the low-carbon and environmentally friendly driving mode. This button can turn the energy-saving mode on or off. 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 Sport mode is activated, the throttle pedal response becomes very sensitive, and the transmission delays shifting. The transmission will only upshift when the engine speed reaches the redline. 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 car's power will weaken. ECON can be understood as the abbreviation for "economy." In most cases, it is recommended to keep ECON mode on. It should only be turned off when high torque output is needed (e.g., climbing a hill) or when the car is traveling at very high speeds. Pressing the ECON button activates the low-carbon and environmentally friendly driving mode. The ECU, engine, and transmission then intelligently execute the driver's intentions in the most fuel-efficient manner, achieving optimal fuel economy through rapid 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, it cannot operate under certain conditions: When the vehicle speed exceeds 120 km/h, priority is given to speed, and the energy-saving mode automatically deactivates. This means that if the speed exceeds the economical range (typically between 60-90 km/h), the ECON mode will not save fuel. The key to the ECON mode is the use of computer-controlled independent operation while the car is moving, making it 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 hill), the ECU prioritizes ensuring sufficient power to drive the car, and the ECON mode will not function in such cases.
