What are the differences between Audi A4 and A6 models?

As a car enthusiast, I am looking for a detailed comparison between the Audi A4 and A6. I am interested in their performance, design, and features.

The main difference between the Audi A4 and A6 is their size. The A4 is a compact executive car, while the A6 is a mid-size luxury car. Additionally, the A6 offers more advanced technology features, such as the Audi Virtual Cockpit and head-up display.

In terms of performance, the A4 and A6 have similar engine options, but the A6 offers a higher horsepower and torque output. This means the A6 will have a slightly better acceleration and overall driving experience.
