How does the Audi A1's turbocharger improve performance?

I've heard that the Audi A1 has a turbocharged engine, but I'm not sure why or how that helps its performance. Can someone explain the benefits and how it affects driving experience?

The turbocharger utilizes exhaust gases to compress air in the engine, allowing for a greater amount of air and fuel to be burned per cycle. This leads to increased horsepower and torque, resulting in quicker acceleration and improved overall performance.

The turbocharger also helps improve fuel efficiency, as it allows for smaller engines to produce the same amount of power as larger engines. This means you can enjoy a more powerful drive while also saving on gas.
