What is the advantage of a 48-volt mild hybrid system on the Audi A5?

I've seen that some Audi A5 models come with a 48-volt mild hybrid system. How does this system benefit the car's performance and fuel efficiency?

The 48-volt mild hybrid system on the Audi A5 helps improve fuel efficiency by utilizing regenerative braking and a start-stop system, allowing the car's engine to turn off when idling. This can lead to significant cost savings in the long run.

Besides improving fuel economy, the 48-volt mild hybrid system also enhances the car's performance by providing an electric boost when accelerating. This results in quicker and smoother acceleration without compromising fuel consumption.

In addition to helping the environment and saving fuel, the 48-volt mild hybrid system also offers a more seamless and comfortable driving experience. By supplementing the car's engine with electrical power, it reduces vibrations and noise, making for a smoother ride.
