Eco stands for eco friendly or on a cars dashboard eco stands for economy mode.
Eco or eco friendly is something that doesn't harm the environment or doesn't harm the environment as much.
On a car dashboard the word "eco" stands for economy mode.
Economy mode or "eco" mode on a car is a driving setting that is designed to improve your cars fuel efficiency by adjusting your vehicle's engine, transmission and the cars climate control systems to use less power.
When the car's "eco" mode is activated it often makes the car's acceleration less responsive and will shift gears sooner to keep the cars engine revolutions low, which reduces the fuel consumption and lowers the cars emissions.
When "eco" mode is on, the cars engine computer or ECU modifies the response to the gas pedal, which makes it less sensitive, so you will need to press the gas pedal further to get the same acceleration as you would in normal mode.
The transmission is also programmed to shift into higher gears more quickly and downshift more slowly in "eco" mode, which keeps the engine RPMs lower to allow for better fuel economy.
And some advanced systems in "eco" mode may even reduce the output of the air conditioner and heating system to decrease the load on the engine.
And in more advanced vehicles, the "eco" mode can also influence the vehicle's start and stop system, which automatically turns off the engine when the car is idling to save on fuel.
"Eco" mode on a car or other vehicle is great for everyday driving and in situations where you're not in a hurry and are driving in city traffic or slower roads and want to maximize the miles per gallon or MPG.
Although the "eco" mode is best turned off when traveling on major highways or on road trips or where you need to keep up with traffic.
The goal of "eco" mode is to provide you with a choice to choose a driving style that improves your fuel efficiency.
But if you need your car's full performance, like when merging onto a highway, overtaking or driving uphill, you should turn the "eco" mode off.
Or if you're driving in situations that require a strong and immediate response from your vehicle you should not use "eco" mode.
