What are the benefits of Audi A1's turbocharged engine?

I am considering buying an Audi A1 and I've heard that it has a turbocharged engine. I am not very technical when it comes to cars, so can someone help me understand the advantages of having a turbocharged engine for this particular car model?

The turbocharged engine in Audi A1 provides more power and torque compared to a regular engine, allowing for quicker acceleration and improved performance overall. With the use of a smaller engine, you also get better fuel efficiency and lower emissions.

Turbocharging provides better low-end torque, meaning you get more power at low speeds without sacrificing fuel efficiency. This is especially useful for city driving and maneuvering through traffic.
