What is the difference between the GT and V10 performance models of the Audi R8?

I'm looking to buy an Audi R8 and I'm wondering what the main differences are between the GT and V10 performance models. Specifically, I'm interested in their performance capabilities and any other unique features they might have.

The main difference between the GT and V10 performance models of the Audi R8 is their respective engines. The GT model features a 5.2-liter V10 engine with 602 horsepower, while the V10 Performance model boasts a more powerful 5.2-liter V10 engine with 602 horsepower. Other notable differences include the GT's lightweight carbon fiber body and unique aerodynamic design, as well as the V10 performance's all-wheel-drive system for enhanced handling and stability.
