What is the difference between the Audi A8's V6 and V8 engine?

I am having trouble deciding between the Audi A8's V6 and V8 engine. Can someone help explain the key differences between the two and provide a recommendation?

The main difference between the V6 and V8 engine in the Audi A8 is the number of cylinders. The V6 has six cylinders while the V8 has eight. This means the V8 will generally have more power and torque, making it better for performance-oriented drivers. However, the V6 may be more fuel efficient and affordable. Considering your priorities and budget, I would recommend test driving both options before making a decision.
