What are the differences between Audi A1 and A3?

I am trying to decide between buying an Audi A1 or A3. What are the key differences between these two models in terms of performance, features, and pricing?

The Audi A1 and A3 are both great cars, but they have some key differences. The A3 has a more powerful engine and offers better performance, but the A1 is more fuel efficient and has a more affordable price tag.

If you're looking for better fuel efficiency and a lower price, go for the Audi A1. However, if speed and performance are what you're after, the A3 is the way to go.
