What is the difference between Audi e-Tron's regenerative braking and traditional braking systems?

I am considering buying an Audi e-Tron and I am confused about the regenerative braking system. How does it work and how is it different from a traditional braking system? Will it save me money on brake repairs in the long run? Thanks.

The Audi e-Tron's regenerative braking system uses the electric motor to slow down the car and convert the kinetic energy into electricity. This electricity is then stored in the battery for later use. Traditional braking systems use friction to slow down the car, which results in heat and wear on the brake pads. In the long run, this can save you money on brake repairs and replacements.

The regenerative braking system in the Audi e-Tron is activated when you take your foot off the accelerator. This means that in stop-and-go traffic, you can often slow down without ever needing to use the brake pedal. This results in a smoother driving experience and can even increase the range of your car.
