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

I am considering purchasing an Audi A8 and I'm confused about the different models. Can someone explain the key differences between the Audi A8 L and the Audi A8 TFSI?

The main difference between the Audi A8 L and the Audi A8 TFSI is in their size and engine. While the A8 L is a long wheelbase luxury sedan, the A8 TFSI is a shorter wheelbase sporty sedan. The A8 L also comes with a larger V8 engine compared to the TFSI's V6, providing more horsepower and torque for a smoother ride.

Apart from the size and engine, another major difference between the Audi A8 L and Audi A8 TFSI is in their interior features. The A8 L comes with a more luxurious and spacious interior, perfect for those who prioritize comfort and prestige. On the other hand, the A8 TFSI is more focused on performance and offers a sportier interior design with features like sport seats and a more dynamic dashboard layout.
