What makes the Audi R8 engine unique and powerful?

I have heard a lot about the Audi R8's engine, but I am curious about what specific features make it stand out from other car engines. Can anyone offer some technical insight?

The Audi R8's V10 engine is unique in that it is a dual-injected engine, meaning it can inject both fuel and air directly into the combustion chambers. This results in a more efficient and powerful engine compared to traditional port fuel injection engines.

In addition to its dual injection system, the Audi R8's engine also utilizes direct injection, where fuel is injected directly into the combustion chamber without going through the intake valves. This allows for precise and controlled fuel delivery, resulting in increased performance and efficiency.

The Audi R8's engine is also equipped with a dry sump lubrication system, which allows for better lubrication and cooling of the engine during high performance driving. This helps to prevent overheating and reduces wear and tear on the engine.
