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

I am interested in purchasing an Audi A3 but I noticed there is also the A3 Sportback version. Can someone explain the main differences between these two models, in terms of features and performance?

The main difference between the Audi A3 and A3 Sportback is the body style. The A3 has a classic sedan design while the A3 Sportback has a sportier hatchback design. In terms of features and performance, the A3 Sportback offers slightly more cargo space and a slightly higher fuel efficiency due to its lighter weight.
