What makes the Audi R8 engine so powerful?

I've heard that the Audi R8 has one of the most impressive engines in its class, but what specific factors contribute to its impressive horsepower and torque?

The Audi R8's 5.2-liter V10 engine is a major factor in its power, producing up to 602 horsepower and 413 lb-ft of torque. This impressive output is due to its high-revving capability and direct fuel injection system.

In addition to its powerful engine, the Audi R8 also utilizes a lightweight and rigid aluminum and carbon fiber construction for improved performance and handling. This design also helps to reduce overall weight and increase fuel efficiency.
