What is regenerative braking and why is it important for the Audi e-Tron?

I've heard that the Audi e-Tron has regenerative braking technology. What does that mean and why is it beneficial for this electric vehicle?

Regenerative braking is a feature that allows the electric motors in your Audi e-Tron to recover energy while you're braking or decelerating. Essentially, it converts some of the kinetic energy from your car's motion into electrical energy, which is then stored in the battery. This not only helps to extend your vehicle's range, but it also reduces wear and tear on your brake pads.
