What are the differences between the Audi A1 and A3 models?

I am looking to upgrade my car and I am considering between the Audi A1 and A3 models. I am wondering what the main differences are between these two models in terms of performance, features, and price.

The Audi A1 and A3 models both offer great performance, but the A3 has a more powerful engine and better handling due to its larger size. In terms of features, the A3 has more advanced technology and luxury options available. However, the A1 is significantly more affordable. Ultimately, it depends on your budget and priorities.
