What is the difference between Audi A8 and Audi A8 L?

I've been looking at the Audi A8 series and noticed that there are both Audi A8 and Audi A8 L models. Can someone explain what the difference is between these two? Do they have different features or performance? Thanks!

The main difference between the Audi A8 and Audi A8 L is the length. The Audi A8 has a standard wheelbase and measures at around 207 inches, while the Audi A8 L has a longer wheelbase and measures at around 211 inches. This results in more legroom and a smoother ride in the Audi A8 L.

Another difference between the Audi A8 and Audi A8 L is the availability of certain features. The Audi A8 L comes standard with features like four-zone climate control and a panoramic sunroof, while these features are optional in the Audi A8.
