Why does the Audi A8 have a V6 engine instead of a V8 engine?

I noticed that the Audi A8, a luxury sedan, comes with a V6 engine instead of a V8 like many other luxury cars. Why is that? Does it affect the car's performance?

The Audi A8 uses a V6 engine because it is more fuel efficient and environmentally friendly compared to a V8. It still provides sufficient power and performance for a luxury car.

V6 engines are lighter and more compact, making them suitable for a sedan like the Audi A8. The car's handling and agility is not compromised with a V6 engine.
