What are the key differences between the Audi A8 and A7 models?

Can someone give me a detailed comparison of the Audi A8 and A7 models in terms of engine, transmission, and overall performance?

The Audi A8 offers a more powerful engine with a 12-cylinder option, while the A7 has a V6 engine. Additionally, the A8 comes with an 8-speed automatic transmission, while the A7 has a 7-speed one. In terms of overall performance, the A8 is better suited for long-distance travel while the A7 offers better handling for city driving.

While both models come with Audi's signature Quattro all-wheel drive, the A8 has a more advanced hydraulic suspension system for a smoother ride. However, the A7's standard air suspension can be upgraded to an adaptive air suspension for improved handling and comfort.

If you're looking for a more spacious and luxurious interior, the Audi A8 is the way to go. With more legroom and premium amenities like massaging seats and dual-pane glass, it's the perfect choice for longer trips. On the other hand, the A7 offers a more sporty and sleek exterior design.
