Eco-mode

eco-mode means that the car responds less sensitively to your right food when accelerating

throttle mapping, pedal will usually cause jump in power, but in eco the same pedal press gives less throttle so acceleration ramps in more gently easier to drive smoothly allowing you to use less RPM and save fuel

Eco mode is good for steady predictable driving, city driving, cruising in straight lines in highways stable speed

Not good for accelerating when needing to speed up, merging onto a highway can feel ecomode holding the car back, switching to normal or sport is smart move in this case
