How to use ECO mode properly when driving long distances?

ECO driving mode is one of the functions that manufacturers equip on many new car models with the purpose of helping the car save more fuel. Depending on the manufacturer as well as each car model, ECO mode is set with its own characteristics and operating methods.

Specifically, ECO mode on hybrid vehicles helps the gasoline engine and electric motor coordinate smoothly and reduce energy load when not needed. Meanwhile, on cars with internal combustion engines running on gasoline or diesel; ECO mode helps limit fuel consumption pumped into the engine, to optimize performance under normal operating conditions. However, is ECO mode really suitable in all conditions when driving long distances and does it really help the car save more fuel than usual (!?).

How does ECO driving mode work in cars?

When activated, ECO mode typically changes the operation of the engine and transmission. Focusing primarily on fuel economy. Specifically, ECO mode operates based on the principle of controlling the opening of the throttle valve, throttle valve and fuel injection system to limit the condition of excess fuel being loaded into the cylinder. This will reduce fuel consumption, while helping to optimize combustion efficiency.

In addition, ECO mode also changes the timing of gear changes. On automatic cars, when activated, ECO mode will calculate to shift to a higher gear sooner, and downshift more slowly to maintain the engine speed at the lowest level, helping to optimize fuel efficiency. On some models, ECO mode is also set to fine-tune performance by reducing the fan speed of the air conditioning system, supporting effective fuel economy.

Is ECO mode really economical, suitable for all driving conditions?

ECO mode can help reduce fuel consumption whether driving in the city, on the highway or on the highway. In the process of developing and applying ECO mode to new car models, car manufacturers have found that ECO mode can improve fuel efficiency by 5 - 10%, helping users save significant fuel costs. However, there are still some notes for drivers when using ECO mode for long-distance driving.

ECO mode can improve fuel efficiency by 5 - 10%, helping users save significant fuel costs.

First, in ECO driving mode, the engine and gearbox react slower than in normal driving mode. This makes the car not really quick and responsive when the driver wants to accelerate to overtake the car in front. Therefore, when the car is in ECO mode, if you want to overtake the car in front, the driver needs to accelerate, create momentum and pay attention.

ECO mode is really effective when used when the car is moving on flat roads, at a constant speed. However, it is not very suitable when going through mountain passes or slopes. Because the accelerator and rpm are limited, the car will be sluggish when going uphill, making the driver feel uncomfortable, feeling like the car is lagging when pressing the accelerator. In addition, ECO driving mode can also affect other systems, such as the cruise control system or the brake assist system.

In short, using ECO mode when driving long distances will help the car save fuel. However, depending on each road and terrain, the driver should calculate and choose to change the driving modes to bring about fuel efficiency while still ensuring safety.
