Can the car stay in ECO mode for a long time? Can ECO mode really save fuel?

I have been engaged in the automobile industry for more than ten years, and have a deep understanding of various driving modes of automobiles, and have specially done experiments on the influence of various driving modes on fuel consumption. There is no doubt that ECO mode can really save fuel. If you drive normally in D or S gear and start the ECO mode, you will obviously feel that the transmission gear will increase, the engine speed will decrease and the vehicle power will decrease. This signal is that you are using fuel-saving mode at the expense of vehicle power.

In ECO mode, the engine output torque is small, the fuel injection quantity is relatively uniform and stable, and the combustion efficiency will be higher. For the transmission, different driving modes adopt different shift diagrams. The shift chart of ECO mode is active in upshifting, but it is not easy to downshift. The vehicle transmission does not actively shift gears and often runs in one gear. In this case, the vehicle power is obviously not good.

Some people told us that ECO mode is not fuel-efficient, mainly because these people have a great demand for vehicle power when driving, often stepping on the accelerator deeply and even accelerating and decelerating. When accelerating overtaking, the accelerator pedal is even more uncertain. In this case, it is normal for a car not to save fuel. After all, what we want is power. If you step on the accelerator deeply, the engine will inject more fuel, and the fuel will not burn fully, which will inevitably lead to an increase in automobile fuel consumption. Therefore, the ECO mode is fuel-efficient, aiming at people who are gentle in driving, have low requirements for automobile power and can drive smoothly.

For car owners, I personally suggest that the city choose normal mode. In this case, the vehicle has both power and fuel consumption. The owner will not think that the vehicle is too fleshy and the power will not be too strong. At the same time, fuel consumption is acceptable. This situation belongs to the best working condition. For sports mode, it is mainly used for overtaking and acceleration, which requires strong power. ECO mode, suitable for slow driving, has low requirements for vehicle power, and cares more about fuel consumption.

Everyone can choose the appropriate driving mode according to their own needs. If in doubt, you can pay attention to and consult the "Car Profile".
