What is the difference between the Audi A6 and A7 models?

I am considering purchasing either an Audi A6 or A7, but I am not sure what sets these two models apart. Can anyone provide some insight on their differences?

The Audi A6 and A7 are both luxury sedan models, but the A7 is considered a sportback with a sleeker design and lower roofline. The A6 has a more traditional sedan look with a longer wheelbase for more interior space.

While both models have similar engine options, the Audi A7 also offers a plug-in hybrid variant for those looking for a more fuel-efficient option. The A6 does not currently have a hybrid option.

One major difference between the A6 and A7 is their price. The A7 has a higher starting price due to its sportback design and additional features. If budget is a concern, the A6 may be a better option.
