How does the Audi e-Tron manage its regenerative braking system?

I've read that the Audi e-Tron uses regenerative braking to help recharge the battery. Can you explain how this works and how effective it is?

The Audi e-Tron uses an innovative regenerative braking system that captures energy from braking and stores it in the battery. This not only reduces the wear on the brakes, but also helps prolong the range of the vehicle.

The e-Tron's regenerative braking system can be customized through the vehicle's drive select modes. You can choose to maximize energy regeneration or prioritize a more natural driving experience.

Based on my experience, the regenerative braking system on the Audi e-Tron is highly effective in city driving where there is frequent stop-and-go traffic. It helps to extend the range of the vehicle significantly.
