What are the main differences between the Audi A8 and the A8 L models?

I am interested in purchasing an Audi A8 and want to know what sets the A8 and A8 L models apart from each other in terms of specs and features. Are there any significant differences, or is it just a matter of size?

The main differences lie in the size and passenger capacity. The A8 L is a longer version of the A8, providing more legroom and increasing the maximum seating capacity from 5 to 7.

Another major difference is in the engine options. The A8 L offers a more powerful V8 engine compared to the A8's V6, allowing for a smoother and more responsive driving experience.
