What does the car eco represent?

Car eco represents that the vehicle has activated the energy-saving mode, which has minimal impact on the vehicle itself. The main principle is to comprehensively evaluate the automatic transmission gear, engine speed, and transmission oil temperature during driving, controlling the engine speed with appropriate gears. Finally, the computer calculates the optimal fuel amount to provide the engine for operation. As an energy-saving mode for cars, eco is mainly divided into active and passive types. Most models on the market currently use the active eco mode, which allows the owner to manually turn it on or off, and it is generally more suitable for use on urban roads. The passive type does not have a separate button but includes a reminder function. When the vehicle speed exceeds 20 kilometers per hour, eco intelligently evaluates the fuel consumption and displays it in green on the dashboard. The eco mode automatically disappears when encountering uphill climbs or acceleration.
I've driven quite a few cars with ECO mode, and this feature is really practical. ECO stands for Ecology, meaning ecological mode, primarily aimed at fuel efficiency and environmental protection. When ECO is activated, the car automatically adjusts various parameters, such as reducing throttle sensitivity so that gentle acceleration doesn't result in a sudden surge; the shift logic also changes, upshifting earlier to keep engine RPM lower; the air conditioning becomes milder, with less aggressive cooling or heating. The most noticeable difference is the smoother start, and fuel consumption drops significantly in traffic jams. Of course, the downside is weaker acceleration, so you'll need to turn it off or press the accelerator harder when overtaking. Using it for my daily commute saves me a lot on fuel costs—it's definitely worth trying.
I saw an ECO indicator on the dashboard when driving my friend's new car, and after studying it for a while, I realized it was the economy driving mode. Pressing this button helps the car save fuel as much as possible, making the whole driving experience feel gentler. The throttle response slows down a bit, and even pressing hard won't make the car surge forward immediately. The transmission shifts gears very eagerly, upshifting before reaching 2000 RPM. The air conditioning airflow also reduces, and the engine start-stop frequency increases. This mode is perfect for slow city driving—I used it on the Second Ring Road viaduct and got an extra 50-60 kilometers per tank. However, it's not suitable for highway driving as the power feels insufficient. Simply put, it's a fuel-saving assistant.
