What are the key differences between the Audi A7 Sportback and the RS7?

I'm considering buying an Audi A7, but I'm not sure if it's worth upgrading to the RS7. Can someone explain the main differences between these two models and help me make a decision?

The Audi A7 Sportback is a versatile and stylish luxury sedan, while the RS7 is a high-performance version that offers more power and sportier features. If you prioritize comfort and sleek design, stick with the A7. But if you're looking for a more dynamic and thrilling driving experience, the RS7 would be a better choice.

One of the major differences between the A7 and RS7 is their engines. The A7 comes with a choice of four or six-cylinder engines, while the RS7 boasts a powerful V8 engine. If you want more power and acceleration, the RS7 is the clear winner. But if you're not particularly concerned about speed, the A7 would suit you just fine.
