What is the difference between the Audi R8 5.2 and the 4.2 models?

I am interested in purchasing an Audi R8 and I am wondering what the main differences are between the 5.2 and 4.2 models.

The main difference between the Audi R8 5.2 and 4.2 models is the engine. The 5.2 model comes with a more powerful V10 engine while the 4.2 has a V8 engine. The 5.2 also has a higher top speed and acceleration. If you are looking for a more thrilling driving experience, the 5.2 would be the better choice.
