What is the best engine for the Audi R8?

I am considering purchasing an Audi R8 and I am unsure which engine option to choose. Should I go for the V10 or the V8? Which one provides better performance and fuel efficiency?

In my personal experience, the V10 engine provides a more exhilarating driving experience. The V8 may be slightly more fuel efficient, but the V10's power and sound are unmatched.

I would suggest going with the V10 if performance is your top priority. However, if fuel efficiency is important to you, the V8 may be a better option.
