What are the key differences between the Audi A1 and A3 model?

I am looking to upgrade my current car to a newer model from Audi. Can someone highlight the main technical and performance differences between these two models? Which one would be a better fit for city driving?

The Audi A1 and A3 may seem similar at first glance, but they actually have some notable differences. One key difference is their size - the A1 is a compact car, while the A3 is a mid-size car. This means the A1 is better for city driving, as it is more maneuverable and easier to park.

In terms of performance, the A1 has more agile handling and better fuel efficiency compared to the A3. However, the A3 has a wider range of engine options and is available in both front-wheel and all-wheel drive.

For technology and features, the A3 has a more advanced infotainment system and a larger touchscreen display. The A1, on the other hand, has a more basic setup but still offers important features like Apple CarPlay and Android Auto.
