Why does the Audi A5 have a turbocharged engine?

I've noticed that many Audi A5 models come with a turbocharged engine, but I'm not sure what the benefits are. Can someone explain why a turbocharged engine is used in this car?

The turbocharged engine in the Audi A5 allows for increased power and performance while still maintaining fuel efficiency. It essentially uses exhaust gases to compress air, resulting in a higher air density in the engine and more power output. This is especially useful for smaller engines that may lack power in traditional fuel systems.
