What is the difference between an Audi A8 and A6 A7?

I am considering purchasing a new Audi sedan but I am not sure what the differences are between the A8, A6, and A7 models. Can someone help me understand the distinctions between these three models in terms of features, design, and performance?

The Audi A8 is the flagship sedan of the brand, offering the most advanced technology and luxury features. The A6 and A7 are slightly smaller and more sporty in design, with a focus on performance and handling.

The key difference between the Audi A8 and A6/A7 models is the level of customization available. The A8 offers more options for personalized features, while the A6 and A7 have more standardized packages.

In terms of performance, the A8 offers a more powerful engine and a smoother ride compared to the A6 and A7. However, the A6 and A7 have versatile options for both gas and hybrid models.
