What is the difference between the Audi A8 and A4?

I am planning to purchase an Audi sedan but I am not sure whether to go for the A8 or the A4. Could someone please explain the key differences between these models, in terms of performance, features, and price?

The A8 is a full-size luxury sedan, while the A4 is a compact executive car. This means that the A8 has a larger and more spacious interior, higher performance capabilities, and a higher price range. On the other hand, the A4 is more fuel-efficient and has a lower starting price. Consider your priorities and budget when making your decision.

The biggest difference between the A8 and A4 is their engine types. The A8 offers a range of powerful V6 and V8 engines, while the A4 has a smaller and more efficient 4-cylinder engine. If you prioritize performance and don't mind a higher gas bill, the A8 is a great choice. Otherwise, the A4 still offers a decent amount of power with better fuel economy.
