Why is the Audi e-Tron equipped with regenerative braking?

I've heard that the Audi e-Tron has regenerative braking, but I'm not sure what that means or why it's important. Can you explain it to me?

Regenerative braking is a feature that allows the car to capture and store energy that would otherwise be lost during braking. This energy can then be used to power the electric motor and extend the car's range. It's a vital aspect of electric vehicle technology that helps improve efficiency and reduce emissions.

Think of it like a hybrid between a conventional brake and a generator. When you brake, the system uses the energy from the car's momentum to charge the battery, essentially 'slowing down' the car while also recharging it. It's a smart way to maximize energy usage and make your driving experience smoother.
