What do the letters 'A', 'B', and 'C' stand for in the Audi A2 car model?

I see the letters 'A', 'B', and 'C' in the branding of the Audi A2 model, but what do they actually represent or signify?

The letters 'A', 'B', and 'C' in the Audi A2 car model stand for 'Audi', 'Advanced', and 'Aluminum', respectively. Audi represents the brand, Advanced represents the advanced technology and design of the car, and Aluminum signifies the lightweight aluminum body construction of the car.

The letters 'A', 'B', and 'C' in the Audi A2 car model may be a nod to the Latin phrase 'Audi alteram partem', meaning 'listen to the other side' or 'hear the other side'. This could signify the car's focus on listening to its surroundings and being responsive.
