How does the Audi R8 engine improve performance and handling?

I've heard a lot about the special engine in the Audi R8, but I'm not sure exactly how it makes the car perform better. Can anyone explain?

The Audi R8 uses a mid-mounted V10 engine, which improves the car's weight distribution and adds stability to handling. It also produces a powerful 562 horsepower, giving the car an exhilarating acceleration experience. In addition, the engine's placement low and central to the car's chassis lowers the car's center of gravity, further improving performance.
