What's the difference between an Audi A4 sedan and a Sportback?

I'm trying to decide between an Audi A4 sedan and an A4 Sportback. Both look similar to me, but what are the technical differences between the two models?

The main difference between the Audi A4 sedan and the Sportback is the body style. The A4 sedan has a traditional sedan body with a separate trunk, while the Sportback has a sloping, hatchback-style rear end. This means the Sportback has more cargo space and a more dynamic look, while the sedan offers a more traditional and elegant design.

Another key difference between the Audi A4 sedan and the Sportback is their handling and performance. The Sportback has a slightly lower and wider stance, giving it a sportier and more agile feel on the road. However, the sedan offers a more comfortable and smooth ride, making it a better choice for longer trips.
