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

I'm trying to decide between the Audi A6 and A7 models but I'm not sure what sets them apart. Can someone break down the key differences between these two cars?

The Audi A6 and A7 are both luxury sedans with strong performance and high-end features. The main difference is that the A7 has a sloping roofline and hatchback design, while the A6 has a traditional sedan shape. This translates to a slightly sportier feel in the A7 and more cargo space in the A6.

One of the biggest differences between the A6 and A7 is their powertrain options. The A7 offers a potent V6 or V8 engine, while the A6 has a more fuel-efficient four-cylinder engine. If performance is a top priority for you, the A7 is the way to go.

As for technology, the A6 and A7 share many of the same features including Audi's MMI infotainment system and virtual cockpit. However, the A7 also has gesture control technology for a more interactive and convenient driving experience.
