What is the difference between the Audi A4 and the A6?

I'm in the market for a new car and considering the Audi A4 or A6. What are the key differences between these two models?

The main difference between the Audi A4 and A6 is their size and luxury levels. The A6 is larger and more luxurious, with a higher price point, while the A4 is smaller and more affordable. It ultimately depends on your personal budget and needs.

Another key difference is the engine options available. The A6 has a wider range of powerful engines to choose from, while the A4 has a more limited selection. If you prioritize performance, the A6 may be the better option for you.

Safety features are also a factor to consider. The A6 has some advanced safety technologies, such as adaptive cruise control and lane departure warning, as standard features, while these may be optional or not available on the A4.
