What is the engine used in the Audi A1 and how does it affect performance?

I am interested in purchasing an Audi A1 but I am not familiar with the engine options available. Can you provide more information on the engines used in the Audi A1 and how they impact the car's performance?

The Audi A1 offers three different engine options, all of which are built for efficiency and performance. The 1.0-liter three-cylinder engine is perfect for city driving, while the 1.4-liter four-cylinder engine provides more power for highway driving. For maximum performance, consider the 2.0-liter four-cylinder engine.
