How does the energy-saving mode on the Audi A2 work?

I've noticed an energy-saving mode on my Audi A2 but I'm not quite sure how it works or if it makes a significant difference in fuel efficiency. Can someone please explain how it works and whether it's worth using?

The energy-saving mode on the Audi A2 works by optimizing the car's performance to reduce fuel consumption. It does this by adjusting the engine and transmission's responsiveness, as well as controlling other components like the air conditioning and auxiliary systems. While it may not make a huge difference in fuel efficiency, it can help save some gas in the long run. My personal advice would be to use it when driving in the city or in heavy traffic.

The energy-saving mode on the Audi A2 is designed to be used when driving on highways or long stretches of road at a constant speed. It works by optimizing the car's speed and power, which can lead to a slight increase in fuel efficiency. My recommendation would be to use it when going on long trips to get the most out of your gas tank.

I've found that the energy-saving mode on the Audi A2 works best when driving at lower speeds. It helps reduce fuel consumption by limiting the amount of power needed to accelerate and maintaining a more economical speed. My advice would be to use it when driving in the city or on rural roads.
