What does the engine size mean in the Audi A1?

I'm considering buying an Audi A1, but I'm confused about the engine size. Can you explain what it means and what effect it has on the car's performance?

The engine size, also known as displacement, refers to the total volume of all the cylinders in a car's engine. Generally, a bigger engine size means more power and torque, which can improve a car's acceleration, top speed, and towing capacity.

When choosing the engine size, consider your driving needs and preferences. A smaller engine may be more fuel efficient and suitable for city driving, while a larger engine may offer more power for highway driving or towing.
