Why is the 2021 Audi A6 equipped with a 48-volt mild hybrid system?

I've heard that the 2021 Audi A6 comes with a 48-volt mild hybrid system, but I'm not sure what that means or why it's important. Can you explain the technology and its benefits?

The 48-volt mild hybrid system in the 2021 Audi A6 is a form of electrification that uses a small battery and an integrated starter generator to assist the engine during acceleration and allow for more efficient start/stop functionality. This results in improved fuel economy and reduced emissions, making it a great choice for eco-conscious drivers.
