What are the main differences between the Audi A8 and the Audi A8L?

I am considering buying an Audi A8 but I'm not sure which model to choose. Can you explain the key differences between the Audi A8 and the Audi A8L in terms of design, features, and performance? Thank you.

The main difference between the Audi A8 and the Audi A8L is the length. The A8L is 5.1 inches longer, providing more legroom and space for passengers in the rear seats.

In terms of design, the Audi A8L has a longer wheelbase and a more elegant, elongated appearance compared to the Audi A8. Both models have a sleek, modern design and offer a range of customizable options.
