What is the difference between the Audi R8 trim levels?

I am interested in buying an Audi R8 but I am confused about the different trim levels available. Could someone explain the differences between them, such as performance specs, features, and prices?

The Audi R8 comes in three trim levels: R8 V10, R8 V10 Performance, and R8 V10 Decennium. The difference between these trims lies primarily in the engine power and features. The R8 V10 has 562 horsepower, the R8 V10 Performance has 602 horsepower, and the R8 V10 Decennium has 620 horsepower. Additionally, the Decennium has unique features such as carbon-ceramic brakes and a special interior design. Prices for the R8 range from $169,900 for the R8 V10 to $208,100 for the R8 V10 Decennium.
