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

I'm interested in the Audi R8 but I'm not sure which engine option to choose. Can someone explain the technical differences between the V8 and V10 engines?

The biggest difference is power: the V10 engine produces 562 horsepower while the V8 has 532 horsepower. This translates to a 0-60 mph time of 3.7 seconds for the V10 and 3.9 seconds for the V8.

Another key difference is the sound: the V10 has a more aggressive and throaty exhaust note, while the V8 has a smoother and more refined sound. It really comes down to personal preference.
