How does the Audi A5's engine produce such a high output?

I've heard that the Audi A5 has a surprisingly high horsepower for its size. How is the engine designed to produce such a powerful output?

The Audi A5's impressive performance is largely due to its turbocharged 2.0-liter engine, which delivers 248 horsepower and 273 lb-ft of torque. This is achieved through a combination of direct injection, variable valve timing, and a responsive turbocharger.
