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

I am a car enthusiast and am considering purchasing either the Audi A6 or A7. However, I can't seem to understand the major differences between the two models. Can someone give me a breakdown of their specs and features?

The main difference between the Audi A6 and A7 lies in their body styles. The A6 is a sedan while the A7 is a hatchback. This means that the A7 offers more cargo space and a slightly sportier appearance.

Another major difference is in their powertrain options. The A6 offers a variety of engines including a turbocharged 4-cylinder, V6, and even a plug-in hybrid. On the other hand, the A7 only offers a V6 and V8 engine.

When it comes to interior features, the A7 has a more luxurious feel with its standard leather seats and higher-quality materials. However, the A6 offers similar features as optional upgrades.
