How does the regenerative braking system work on the Audi A2?

Could someone explain the process of how the regenerative braking system works on the Audi A2? I’ve heard it’s a unique feature on this model and I’m curious to know more about it.

The regenerative braking system on the Audi A2 uses a special type of alternator to recapture energy that would normally be lost during braking. This energy is then stored in the car's battery to be used later, increasing efficiency.

I've personally found that the regenerative braking system on the Audi A2 not only increases efficiency, but also gives a smoother and more controlled braking experience.

As a mechanic, I can say that the regenerative braking system is a key part of the Audi A2's overall design, making it a much more eco-friendly vehicle compared to others in its class.
