Why does the Audi A8 use a V8 engine instead of a V12?

I noticed that the Audi A8, a flagship luxury sedan, uses a V8 engine instead of a V12 like most other luxury sedans. Why did Audi make this decision and does it affect the performance or driving experience in any way?

The choice to use a V8 instead of a V12 allows for improved fuel efficiency and a lighter overall vehicle weight. However, it does not compromise the performance of the A8 and still offers smooth and powerful driving.

Audi opted for a smaller engine in the A8 as it fits better with their philosophy of balanced performance and efficiency. The V8 still provides plenty of power and luxury car buyers tend to prioritize comfort and technology over sheer horsepower.
