What is the performance difference between the Audi R8 V10 and V10 Plus?

I am considering purchasing an Audi R8 but can't decide between the V10 and V10 Plus models. Can someone explain the specific performance differences between the two?

The V10 Plus model has a more powerful engine, producing 620 horsepower compared to the V10's 562 horsepower. This results in a 0-60 mph time of 2.9 seconds for the V10 Plus and 3.5 seconds for the V10.

In addition to the increased horsepower, the V10 Plus also has a lighter body thanks to the use of carbon fiber, resulting in improved handling and agility.
