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

I am considering buying a compact car from Audi, but I am unsure about the differences between the A1 and the A3 models. Can someone explain them to me in detail?

Both the Audi A1 and A3 are great options in the compact car category, but there are some important differences you should be aware of. The most significant one is size - the A1 is smaller and more suitable for city driving, while the A3 is slightly larger and more spacious, making it better for longer trips and families.

Design-wise, the Audi A1 has a more youthful and sporty look compared to the mature and refined A3. Depending on your preferences, you can choose between the A1's iconic hatchback design or the A3's sleek sedan style.

In terms of performance, the A1 offers a more responsive and agile driving experience, thanks to its smaller size and lighter weight. On the other hand, the A3 delivers a smoother and more comfortable ride, with its more powerful engines and advanced suspension system.
