What is the difference between the Audi A7 and Audi RS7?

I am trying to decide between the Audi A7 and the Audi RS7. Both cars seem very similar, but what sets them apart? I am a bit confused, can someone please explain the key differences between these two models? Are there any major performance or design variations? Thanks!

The Audi A7 and Audi RS7 may seem similar at first glance, but they are two very different cars. The main difference between these models is their performance capabilities. The Audi RS7 is a high-performance version of the A7, with a more powerful engine and sportier modifications. If you want a car with exceptional acceleration and handling, the RS7 may be the better choice.
