What is the difference between Audi A4 and A6 sedans?

I am considering purchasing a new sedan and am unsure of the differences between Audi's A4 and A6 models. Can anyone provide some insight?

The main differences between the Audi A4 and A6 sedans are their size and performance. The A6 offers a larger cabin and more powerful engine options, while the A4 is a bit smaller and more fuel efficient. It ultimately depends on your specific needs and preferences.

One key distinction between the Audi A4 and A6 is their design. The A4 has a more modern and sporty look, while the A6 has a more classic and refined appearance. It's important to consider your personal style when deciding between the two.
