Which mode is more fuel-efficient, comfort or eco?

ECO saves fuel. ECO is an indicator light that prompts you about the fuel supply status of your vehicle while driving. When the ECO green light is on, it means you are driving in a fuel-efficient state. When the ECO light is off, it indicates that your vehicle is not in a fuel-efficient driving mode. Cases where it is unnecessary to activate ECO: In a few situations, it is unnecessary to activate ECO: 1. When the car is driving at high speed (up to 100km/h), even if ECO is turned on, the vehicle's computer will prioritize speed, and the ECO mode will automatically deactivate. 2. When a high torque output is needed, such as when climbing a mountain, the engine computer will prioritize ensuring and providing sufficient power to drive the vehicle, and the ECO mode will automatically deactivate. Location of the ECO button: The ECO button is generally located on the left side of the car, with the letters ECO on the button. Some buttons are green in color, making them easy to identify.
As an ordinary person who often drives in the city, I find the eco mode definitely saves more fuel. At first, I preferred comfort mode because it drives smoothly with quick throttle response, but after actual comparison, I found it burns fuel extremely fast. In eco mode, the car limits acceleration and the engine isn't as aggressive, significantly reducing fuel consumption in stop-and-go city traffic—saving about 10% on fuel costs. I've tested it several times with my own car: the fuel gauge drops scarily fast in comfort mode; it's much steadier in eco mode. The downside is slightly slower acceleration, but you get used to it. Combined with gentle throttle application and anticipating red lights, eco mode works even better. Don't always think about overtaking; drive calmly and fuel savings come naturally. Now I use eco mode most of the time, especially during rush hour commutes with frequent red lights—it's simply a lifesaver!
Having driven for many years, I clearly understand the differences between modes. The eco mode is designed for fuel efficiency by reducing engine output, optimizing shift points, and minimizing inefficient combustion. In contrast, the comfort mode emphasizes a smooth and responsive acceleration, causing the engine to frequently operate outside its most efficient range, naturally leading to higher fuel consumption. In daily driving, such as commuting to and from work, the fuel-saving effect of eco mode is particularly noticeable, especially in low-speed urban sections. On long highway trips, the comfort mode may slightly increase fuel consumption, but it's not a fundamental issue. The key lies in cultivating good driving habits—smooth starts, avoiding sudden braking, and combining these with eco mode to maximize fuel savings. I recommend that new drivers use eco mode more often to get accustomed to driving rhythm while also paying attention to regular tire pressure checks to ensure good rolling resistance. These small details can also help save fuel.
