What is the difference between the Audi R8 and RS8?

I am interested in purchasing an Audi R8 or RS8, but I am not sure what sets these two models apart. Can someone explain the main differences between the R8 and RS8?

The biggest difference between the Audi R8 and RS8 is their engine. The R8 comes with a V10 engine, while the RS8 has a V8. This means the RS8 has less power, but it's also lighter and more agile on the road. If you're looking for brute force, go for the R8. If you prioritize handling, the RS8 may be a better choice.
