How is the Audi e-Tron's regenerative braking different from traditional braking systems?

I've heard that the e-Tron uses regenerative braking to recharge its battery. Can you explain how this works and why it's beneficial?

Regenerative braking is a feature of electric and hybrid vehicles that converts the kinetic energy of braking into electricity, which is then stored in the battery for future use. This means that when you brake in the e-Tron, you are simultaneously recharging the battery. This type of braking is more efficient and produces less wear and tear on the brakes.

Compared to traditional braking systems, regenerative braking in the e-Tron allows for a smoother and more controlled deceleration. It also reduces the need for frequent brake replacements, saving you money in the long run.
