Why does the Audi A7 use a 48-volt electrical system?

I've heard that the Audi A7 uses a unique 48-volt electrical system, unlike other cars. Can you explain the reasoning behind this decision?

The 48-volt electrical system is used in the Audi A7 to support various advanced features and technologies such as active suspension and mild-hybrid systems. This allows for improved performance and efficiency in the vehicle.

By using a 48-volt electrical system, the Audi A7 is able to handle the high power demand of its advanced features without relying solely on the traditional 12-volt battery. This ensures a more stable and reliable electrical system for the car.

With a 48-volt electrical system, the Audi A7 is also able to implement regenerative braking, which helps to recharge the battery and improve overall fuel efficiency. This is just one of the many benefits of this unique system.
