How does the Audi A8 48-volt mild hybrid system work?

I have read that the Audi A8 has a 48-volt mild hybrid system, but I am not sure how it works. Can you please explain it to me?

The 48-volt mild hybrid system in the Audi A8 uses a belt alternator starter (BAS) to help improve fuel efficiency and reduce emissions while providing additional power. The BAS allows the car to coast with the engine off at speeds between 34-99mph, while the lithium-ion battery stores energy from regenerative braking to power the BAS and electrical components. This system also allows for smoother and faster start-stop functionality, making driving more comfortable and efficient.

The 48-volt mild hybrid system in the Audi A8 is a great addition to this luxury sedan. The BAS not only helps improve fuel economy and reduce emissions, but it also provides an extra boost of power when needed. Additionally, the system is seamlessly integrated into the car's design and functions without causing any disruptions or added maintenance.

I have been driving the Audi A8 for a few months now and I can confidently say that the 48-volt mild hybrid system has made a noticeable difference in my driving experience. The transition from engine on to engine off is smooth and almost imperceptible, and I have noticed an improvement in my overall fuel efficiency and reduced trips to the gas station. As a bonus, the BAS also helps reduce wear and tear on the engine and other components, potentially leading to longer-term cost savings.
