Why does the Audi A6 use direct fuel injection?

I've heard that the Audi A6 has direct fuel injection, but I'm not sure why that would be beneficial. Can anyone explain the advantage of this feature?

The direct fuel injection system in the Audi A6 allows for more precise fuel delivery, resulting in improved performance and fuel efficiency. Additionally, it reduces the amount of carbon emissions, making it more environmentally friendly.

Direct fuel injection is also known for providing a smoother and more responsive driving experience, as it allows for quicker throttle response and more accurate engine control.

In comparison to traditional fuel injection systems, direct fuel injection can also prevent excessive build-up of carbon deposits on the engine, increasing its longevity.
