What is the difference between the Audi R8 V8 engine and the R8 V10 engine?

I am considering purchasing an Audi R8 and I am trying to decide between the V8 and V10 engine options. What are the technical differences between these two engines and what kind of driving experience can I expect from each?

The Audi R8 V8 engine has 430 horsepower and 316 lb-ft of torque, while the R8 V10 engine has 562 horsepower and 406 lb-ft of torque. This means that the V10 engine has significantly more power and torque, resulting in a faster and more exhilarating driving experience.
