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. Here 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 only upshifts when the engine speed reaches the redline. After switching to Sport mode, the engine speed is maintained at around 3,000 RPM, providing 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 weakens. ECON can be understood as an abbreviation for "economy." In most cases, it is recommended to keep ECON mode enabled. However, it should 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 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. 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. Although ECON mode is simple and effective, it does not work under certain conditions: When the vehicle speed exceeds 120 km/h, priority is given to maintaining speed, and the Eco 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 the car's computer to operate independently while driving. Therefore, it does not function during idle parking, or when the car is in N, P, or manual mode. When the car needs to overcome significant resistance or output high torque (e.g., climbing hills), the ECU prioritizes ensuring sufficient power to drive the vehicle, and ECON mode will not work in such cases.

I just test-drove a Hyundai from Beijing Hyundai, and the ECON button usually serves as the switch for the economy mode. Pressing it automatically optimizes the engine performance, air conditioning system, and transmission to slightly reduce fuel consumption. For example, in stop-and-go city traffic, it helps minimize unnecessary acceleration, making the overall drive smoother and more fuel-efficient. When commuting with ECON mode on, I clearly noticed that the fuel tank lasts longer. This feature is particularly useful in heavy traffic and is also environmentally friendly by reducing emissions. However, a quick reminder: when climbing hills or needing more power on highways, it’s better to turn it off to avoid affecting driving performance. Most Hyundai models come with ECON mode, and it’s easily accessible on the center console—simple and convenient to set up. Trying it out a few times while driving can help you get used to this feature, making daily commutes more economical.

As a veteran driver with over a decade of experience behind the wheel of a Hyundai Beijing, I frequently use the ECON button, which stands for Economic Driving Mode. Simply put, it optimizes vehicle settings to save fuel. When activated, it reduces engine output and makes the air conditioning system operate more efficiently, thereby improving overall fuel economy. Especially during peak-hour traffic jams, ECON keeps the car running at low RPMs, avoiding unnecessary fuel consumption. The benefits are obvious: significant annual fuel savings and a contribution to environmental protection. However, one thing to note is that when rapid acceleration or overtaking is needed, the power output may feel insufficient, making the car seem underpowered. In such cases, promptly switching back to normal mode is safer. New car owners are advised to start by studying the manual and then adjust their driving habits to complement ECON in practice. Maintaining proper tire pressure also enhances its effectiveness.

The first time I drove a Beijing Hyundai SUV, I didn't quite understand what ECON meant, but later learned it stands for Economy Mode. This feature is located on the vehicle control panel—pressing it activates a fuel-saving state that helps reduce engine load and air conditioning consumption. When enabled during daily driving, it stabilizes the car's performance for lower fuel consumption, making it especially cost-effective for short trips in the city. I recommend new owners try this setting—it saves money without hassle. Just remember to monitor road conditions and decide whether to turn it off during long trips or rainy weather. Overall, ECON is a practical highlight of Hyundai vehicles, promoting greener travel.
