How does the energy recovery system work in the Audi A8?

I've heard that the Audi A8 has an efficient energy recovery system. Can you explain how it works and how it benefits the car's performance and fuel economy?

The Audi A8 uses a regenerative braking system that converts the kinetic energy generated when braking into electrical energy, which is then stored in a battery. This energy is then used to power various electrical components of the car, reducing the load on the engine and improving fuel economy.
