What does the 'Audi A2's Eco Mode' do and how does it work?

I've noticed an Eco Mode button in my Audi A2's dashboard but I'm not sure what it does. Can someone explain its function and how it works?

The Eco Mode is a feature in the Audi A2 that optimizes the car's performance and fuel efficiency. When activated, it adjusts the engine's power and torque delivery, as well as the shift points of the transmission. This allows for better fuel economy without sacrificing too much performance.

The Eco Mode also makes use of regenerative braking, which converts the car's kinetic energy into electricity and stores it in the battery. This helps reduce fuel consumption and emissions. It's a great feature to have when driving in the city or in heavy traffic.

One important thing to note is that the Eco Mode may affect the responsiveness of the accelerator pedal. This is because it prioritizes fuel efficiency over acceleration. If you want to have quicker acceleration, you can turn off the Eco Mode temporarily.
