What are the main differences between the Audi A4 and A6?

I am trying to decide between purchasing an Audi A4 or A6 and I would like to know the main differences between the two models in terms of performance, features, and overall value.

The main difference between the Audi A4 and A6 lies in the size and power of the vehicle. The A6 offers a larger and more powerful engine, making it a better choice for those seeking a high-performance vehicle.

In terms of features, the A4 and A6 are very similar, with both offering luxurious interiors and advanced technology. However, the A6 does have a few extra features such as a larger infotainment screen and more driver assistance options.
