Why does the Audi A8 have a mild-hybrid system?

The Audi A8 is known for having a mild-hybrid system, but why was this technology chosen over others and what benefits does it offer?

The reason for the mild-hybrid system in the Audi A8 is to improve fuel efficiency and reduce emissions. It works by using a small electric motor and battery to assist the gasoline engine, resulting in a smoother and more efficient driving experience. As a happy Audi A8 owner, I highly recommend this feature to anyone looking for a luxury car that is environmentally conscious.
