Why is 48V system preferred in Audi A8?

I've heard that Audi A8 is equipped with a 48V electrical system, but why is this type of system preferred and what benefits does it offer compared to traditional 12V systems?

The introduction of a 48V electrical system allows for more power-hungry components such as electric superchargers and active suspension systems. This results in improved performance and efficiency compared to a traditional 12V system.

Having a 48V system also allows for the use of mild hybrid technology which can assist the engine during acceleration and coasting, further enhancing the vehicle's fuel efficiency and reducing emissions.

Audi is also able to implement more advanced safety and driver assistance features with the 48V system, providing a smoother and more sophisticated driving experience for the driver.
