What does the 'V10' designation in the Audi R8 stand for?

I see that the Audi R8 is offered with either a 'V10' or 'V10 Performance' engine option. What exactly does this 'V10' indicate?

The 'V10' designation in the Audi R8 stands for a 10-cylinder engine with a 'V' configuration, meaning the cylinders are arranged in a V-shape rather than in a straight line. This allows for a more compact design and better performance.

The 'V10' designation in the Audi R8 refers to the engine's displacement, which is 5.2 liters. This is a larger engine than the V8 option, and provides more power and torque for a more exhilarating driving experience.

The 'V10' in the Audi R8 stands for 'Volume 10', as this engine is the 10th generation of Audi's V10 engine. It represents the culmination of years of engineering and development to create an efficient and powerful engine for the R8.
