What is the difference between the Audi R8 and the other R-series models?

I am interested in buying an Audi R-series model, but I am not familiar with the differences between the R8 and the other models. Can someone explain them to me?

The Audi R8 is the flagship model of the R-series and is designed for high performance driving with a more aggressive look and feel. The other R-series models, such as the RS3 and RS5, are more geared towards everyday driving with a focus on luxury and comfort.

The main difference is in their engine configurations. The Audi R8 boasts a V10 engine, while the other R-series models have smaller, four-cylinder engines. Additionally, the R8 has a mid-engine layout, providing better balance and handling compared to the front-engine layout of the other models.
