What are some key differences between the Audi A6 and A7 models?

I am trying to decide between an Audi A6 and A7, but I'm not sure what sets them apart. Can someone explain the main differences between these two models in terms of features and performance?

The main difference between the Audi A6 and A7 is their body style. The A6 is a sedan, while the A7 is a sportback with a hatchback design. This allows for a more spacious trunk and a more sleek look overall.

Another key difference is the engine options. The Audi A6 offers a standard 2.0-liter turbocharged four-cylinder engine, while the A7 has a standard 3.0-liter V6. This means that the A7 has more power and torque.

The Audi A7 also has a more advanced infotainment system with dual touchscreens compared to the single touchscreen in the A6. This allows for easier navigation and access to functions while driving.
