Under what circumstances can the car's eco mode be used?

[Donovan]

Eco mode is generally used in suburban areas, national highways, and rural roads where the roads are wide and traffic is sparse. Introduction to Eco Mode: ECO mode, also known as economy mode, means that under this mode, the engine will be very fuel-efficient. The fuel-saving effect of ECO mode is quite noticeable when the vehicle is frequently driven in congested urban traffic conditions. However, there is no difference in fuel consumption compared to normal driving when traveling on suburban roads or highways. Therefore, ECO mode is best used in congested urban traffic conditions. Principle of Eco Mode: The working principle of eco mode is achieved by changing the transmission's shift timing, altering the sensitivity of the accelerator pedal, and adjusting the output power of the air conditioning system. Under eco mode, the transmission will shift gears as early as possible, resulting in the engine feeling somewhat underpowered and the vehicle's acceleration performance potentially weakening. Changing the sensitivity of the accelerator pedal means that, under normal conditions, the engine responds immediately when the accelerator pedal is pressed. However, in eco mode, there is a delay of a few seconds before the engine responds after the accelerator pedal is pressed. Some car models also limit the usage power of the air conditioning in eco mode to reduce the engine's load and lower fuel consumption.
