How does Audi's e-Tron regenerative braking system work?

I've been hearing a lot about regenerative braking in electric cars, but I'm not sure how it actually works. Can someone explain the specific process in the e-Tron and how it differs from traditional braking systems?

Hi Sophie, regenerative braking in the Audi e-Tron is actually quite impressive. When you lift your foot off the accelerator, the electric motor acts as a generator, converting the kinetic energy from the car's motion into electrical energy. This energy is then stored in the battery for later use. So essentially, the e-Tron is able to partially recharge itself during braking and deceleration, which helps to extend its range. Compared to traditional braking systems, this process is much more efficient and can even improve the overall performance of the car.
