Why does the Audi A7 have a longer wheelbase compared to its competitors?

I've noticed that the Audi A7 has a slightly longer wheelbase than other luxury sedans in its class. Can you explain why this is and if it has any impact on the car's handling and performance?

The longer wheelbase on the Audi A7 provides more stability and improved handling, especially during high-speed cornering. This is due to better weight distribution and increased contact patch of the tires.
