What engine options are available on the Audi A3?

I am looking to purchase an Audi A3 and I'm considering different engine options. What engines are available on this model and what are the differences between them?

The Audi A3 currently offers three engine options: a 2.0-liter turbocharged four-cylinder, a 2.0-liter turbocharged diesel, and a 1.8-liter turbocharged four-cylinder. The 2.0-liter turbocharged four-cylinder engine is the standard option and provides a good balance of power and efficiency.

If you're looking for more power, the 2.0-liter turbocharged diesel engine is a great option. It offers better fuel economy than the gas engines and has plenty of torque for a more spirited driving experience.

For a fuel-efficient option, the 1.8-liter turbocharged four-cylinder is a good choice. It has a lower horsepower than the other engines, but still provides a smooth and enjoyable driving experience.
