What is the difference between the Audi A4 and A3?

I am interested in purchasing an Audi but I am not sure whether to go for the A4 or A3 model. Can someone explain the differences between the two options in terms of performance, features, and price?

The main difference between the Audi A4 and A3 is their size. The A4 is a mid-size sedan, while the A3 is a compact hatchback. This means the A4 will have more interior space and a larger trunk, but the A3 will be more agile and easier to maneuver in tight spaces.

In terms of performance, the A4 comes with a standard 2.0-liter turbocharged four-cylinder engine, while the A3 has a smaller 1.4-liter turbocharged engine. The A4 also offers a more powerful option with a 3.0-liter turbocharged V6 engine, while the A3 does not have this option.

As for features, the A4 comes with more standard features like leather seats, tri-zone climate control, and Apple CarPlay/Android Auto integration. The A3 has these features available as options. Additionally, the A4 has a more luxurious interior design compared to the A3.
