How does the Audi A1's turbocharger improve engine performance?

I am considering purchasing an Audi A1 and I keep hearing about its turbocharged engine. How exactly does this feature work and how does it impact the car's overall performance?

The turbocharger in the Audi A1 works by forcing more air into the engine, which allows for more efficient and powerful combustion. This results in an increase in horsepower and torque, giving you a faster and more responsive driving experience.

The turbocharger also aids in improving the fuel efficiency of the Audi A1. By increasing the amount of air in the engine, it allows for a leaner fuel-to-air mixture, resulting in better mileage for your car.
