Why does the Audi A6 have a direct-inject technology?

I am curious as to why Audi has chosen to use direct-inject technology in their A6 model. Is it significantly better than traditional fuel injection?

The direct-inject technology used in the Audi A6 offers a more precise and efficient way of injecting fuel into the engine. By directly injecting fuel into the combustion chamber, more power can be produced with less fuel, resulting in improved performance and fuel economy.
