Why does the Audi A7 use a V6 engine instead of a V8?

I noticed that the Audi A7, unlike its competitors, uses a V6 engine instead of a V8. Is there a specific reason for this choice and does it impact the performance of the car?

The Audi A7 opted for a V6 engine to improve fuel efficiency and reduce emissions. While it may not sound as powerful as a V8, the A7's turbocharged V6 engine still delivers impressive performance and a smoother ride.

Audi engineers determined that a V6 engine was the best fit for the A7's design and weight distribution. Don't let the number of cylinders fool you, the A7's V6 produces ample power for a thrilling driving experience.
