What's the difference between the Audi A1 and A3 engines?

I'm looking to purchase a new Audi and am torn between the A1 and A3 models. Can someone explain the differences in their engine performance?

The A3 has a larger and more powerful engine compared to the A1, so it will likely have better performance in terms of acceleration and top speed. However, the A1 may be more fuel efficient.

The A1 is the perfect city car with its smaller engine and compact size. But if you're looking for a more powerful and sporty driving experience, go for the A3.

It ultimately depends on your personal needs and preferences. Take both models for a test drive and see which one feels better for you.
