What is the difference between the Audi A4 and A3 models?

I am thinking about purchasing a new Audi but I am not sure what the differences are between the A4 and A3 models. Can someone please explain?

The main difference between the Audi A4 and A3 models is their size. The A4 is slightly larger and offers more interior space. It also comes with more standard features such as leather seats and a larger infotainment screen. However, the A3 is more fuel efficient and offers a sportier driving experience.

One major difference is their starting price. The Audi A4 has a higher starting price compared to the A3. However, the A4 also comes with more engine options and offers a more luxurious interior. If budget is a concern, go for the A3 but if you want a more premium experience, the A4 is the way to go.
