What does the 'Eco' mode in the Vauxhall Crossland do?

I recently purchased a Vauxhall Crossland and noticed that it has an 'Eco' mode. I'm not sure what this mode does and if it's worth using. Can someone please explain?

The 'Eco' mode in the Vauxhall Crossland optimizes the car's performance to be more fuel efficient. It adjusts the engine's power and reduces energy usage to improve fuel economy. This is perfect for longer trips or when you want to save money on gas.

I've found that the 'Eco' mode also makes the car more responsive and easier to control. I highly recommend using it for smooth driving.

Just keep in mind that the 'Eco' mode may reduce the car's acceleration and speed, as it prioritizes fuel efficiency. If you need more power for merging onto highways or overtaking, I suggest switching to a different mode.
