Eco mode is a fuel-saving feature offered by several car manufacturers that instructs the engine computer to shift into a program that maximizes efficiency over performance. The goal of eco mode is to improve a cars fuel economy as you drive, which not only reduces fuel expenses but also reduces overall emissions. Here are some key features of eco mode:

• Energy-intensive systems: In eco mode, the operation of some energy-intensive car systems, such as air conditioning and steering system, changes.

• Throttle response: Eco mode generally affects throttle response, which means that acceleration will feel slower when pressing the throttle pedal down compared to when it is off.

• Transmission: An automatic transmission will shift to higher gears sooner in eco mode and be slower to downshift for passing.

• Other fuel-saving measures: Depending on the vehicle, eco mode may also invoke other fuel-saving measures, such as altering how air conditioning and electrical systems work.

The exact name of eco mode may change from one automaker to the next, but the goal is always the same: to tailor a cars driving dynamics to fit both the current conditions and the drivers preferences. While eco mode can help improve fuel economy, it may not make a significant difference for drivers with a light throttle foot. However, it can be a useful feature for those who want to reduce their fuel expenses and overall emissions.
