Why does the Audi A3 have a turbocharged engine?

I've noticed that the Audi A3 has a turbocharged engine, but I'm not sure why. Is it more efficient or does it improve performance?

The turbocharged engine in the Audi A3 allows for better fuel efficiency without sacrificing power. It uses exhaust gases to spin a turbine, which then compresses the air entering the engine. This results in a higher air-to-fuel ratio, giving the engine more power.

Not only does the turbocharger increase power and efficiency, but it also helps reduce emissions. By increasing the air intake and optimizing fuel combustion, the Audi A3 is able to meet stricter emissions standards.

Having a turbocharged engine also allows for a more compact and lightweight design, freeing up space for other features and improving overall performance. As technology advances, we can expect even more advancements in turbocharged engines.
