How does the Audi R8 V10 engine achieve high power and efficiency?

I have read that the Audi R8 V10 engine is able to produce 570 horsepower and 550 Nm of torque, while still maintaining good fuel efficiency. how does this technology work?

The Audi R8 V10 engine uses a direct injection fuel system combined with a dual-clutch transmission, allowing for better fuel atomization and improved combustion efficiency.

The Audi R8 V10 engine also utilizes a lightweight aluminum construction and a dry sump lubrication system to reduce weight and friction, resulting in more power output and better fuel efficiency.
