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

I am looking to buy an Audi sedan and I am stuck between the A7 and the A8 models. Can someone explain the key differences between these two models?

The main difference between the A7 and the A8 models is in their size and seating capacity. The A7 is a mid-size coupe with seating for four, while the A8 is a full-size sedan with seating for five.

In terms of design, the A8 has a more traditional sedan look while the A7 has a sleeker, more coupe-like appearance. It really comes down to preference and what you value in a car's aesthetics.

One major difference is in the engine options. The A7 offers a range of gasoline and diesel engines, while the A8 offers a plug-in hybrid option. Consider your driving habits and preferences when deciding between the two.
