How does the Audi A8 engine use a mild hybrid system?

I am interested in buying the Audi A8 and heard it has a mild hybrid system. Can you explain how this system works and how it differs from a traditional hybrid system?

The Audi A8's mild hybrid system uses a 48-volt battery and an integrated starter generator (ISG) to assist the engine during acceleration and to allow for engine start-stop technology. It differs from a traditional hybrid system in that it does not have a large electric motor to power the vehicle on its own, but rather supports the engine to improve efficiency and performance.

The mild hybrid system in the Audi A8 helps to reduce emissions and improve fuel efficiency by shutting off the engine when the vehicle is stopped and using its energy to power electronics and accessories. It also provides a boost of power during acceleration, resulting in a smoother and more efficient driving experience.

The Audi A8's mild hybrid system uses regenerative braking to recharge the 48-volt battery. This means that whenever you brake, the energy normally lost as heat is captured and stored, providing additional power for when you need it.
