Why does the Audi A7 have a longer wheelbase than the A6?

I am considering purchasing either an Audi A7 or A6, but I noticed that the A7 has a longer wheelbase. What is the reason for this difference and how does it affect the performance of each car?

The Audi A7 has a longer wheelbase because it was designed to have a more spacious and comfortable interior for passengers. This longer wheelbase also allows for smoother handling and better stability on the road.

Although the A7's longer wheelbase may make it slightly less nimble in tight spaces compared to the A6, it provides a more luxurious and comfortable ride overall. If you prioritize space and comfort, the A7 may be the better option for you.
