What are the most common types of engine used in an Audi A3?

I am interested in purchasing an Audi A3 but am not familiar with the various engine options available. Can anyone provide information on the most common engine types used in this car model?

The majority of Audi A3 models come equipped with a turbocharged 2.0-liter four-cylinder engine, which offers a good balance between power and fuel efficiency.

If you're looking for a higher-performance option, consider the Audi S3 which features a 2.0-liter turbocharged four-cylinder engine with more horsepower and torque.
