What is the function of the Audi 80's turbocharger?

I've heard that the Audi 80 comes with a turbocharger, but I'm not sure what it does. Can someone explain its purpose and how it affects the car's performance?

The turbocharger in the Audi 80 is responsible for increasing the engine's power output by forcing more air into the combustion chamber. This results in a higher horsepower and torque, making the car faster and more responsive.

In addition to improving performance, the turbocharger also helps with fuel efficiency. By forcing more air into the engine, it allows for a more efficient combustion process, resulting in better gas mileage.
