What is the meaning of Audi's 'A2' classification?

Can someone explain the significance of the 'A2' designation in Audi's car models? I've seen it on various cars but I'm not sure what it stands for.

Audi uses a combination of letters and numbers in their model names to indicate the size and engine type. The 'A' stands for a standard-sized car while the '2' means it is a smaller version within the A-line.

The 'A' in the model name stands for the car's platform and the '2' refers to its positioning in the brand's lineup. So the Audi A2 would be the second smallest car in the brand's range.

The 'A2' classification in Audi's car models stands for the vehicle's size and positioning in the brand's lineup. It is generally used for smaller, compact cars with fuel-efficient engines.
