What sets the Audi R8's V8 engine apart from other cars in its class?

I've heard that the Audi R8 has a special V8 engine, but what makes it different from other cars with V8 engines?

The Audi R8's V8 engine features a unique arrangement of the cylinder banks, called a 'flat-plane' configuration, which results in a more even firing order and improves engine balance and performance.

In addition to its flat-plane design, the Audi R8's V8 engine also utilizes a dry sump lubrication system, which allows for better oil distribution and reduces the risk of oil starvation during high-speed cornering.
