What is the purpose of the Audi R8's V10 engine?

I know that the R8 comes with a powerful 5.2L V10 engine, but what makes it different from other car engines and why did Audi choose to use this specific one in the R8?

The V10 engine in the Audi R8 was originally developed for Lamborghini and was featured in the Gallardo and Huracán. Audi chose to use this engine in the R8 for its performance capabilities, as well as its unique sound and character.

The V10 engine in the Audi R8 has a unique layout, with a 90-degree angle between the two banks of cylinders. This design allows for a shorter and stiffer engine, resulting in improved handling and weight distribution.

Audi also wanted to differentiate the R8 from its smaller sibling, the TT, which uses a smaller and less powerful four-cylinder engine. The V10 engine gives the R8 a more athletic and performance-focused feel.
