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

I am considering buying an Audi car and I have my eye on both the A1 and A3 models. What are the key differences between the two models in terms of performance, features, and price?

The Audi A1 is a smaller and more compact car compared to the A3, making it easier to maneuver and fit into tight spaces. However, the A3 offers more power and a smoother driving experience.

In terms of features, the A3 has more advanced technology and luxury options than the A1. However, the A1 offers great value for money and still has all the basic features you would need in a car.
