What are the differences between an Audi A4 and A6?

I am looking to purchase a new Audi, but I am not sure which model would best suit my needs. What are the main differences between the A4 and A6 models in terms of features, performance, and price?

The main difference between the Audi A4 and A6 is their size and price. The A4 is a compact luxury sedan, while the A6 is a midsize luxury sedan. The A6 also typically has more advanced features and a higher starting price.

While both the A4 and A6 have a similar exterior design, the A6 has a longer wheelbase which translates to more interior space. This may be a consideration if you frequently have passengers or need extra storage room.
