What are the main differences between the Audi A1 and A1 Sportback?

I am considering buying an Audi A1 and I was wondering what the main differences are between the standard A1 and its Sportback version. Is it just the body style or are there other significant distinctions?

The Audi A1 and A1 Sportback have the same overall design and features. The only difference is that the A1 Sportback has a longer body and more interior space, making it a better option for families.

One of the key differences between the Audi A1 and A1 Sportback is the number of doors. The A1 has 3 doors while the A1 Sportback has 5, making it more accessible and convenient for passengers in the back.

Another notable distinction is that the Audi A1 Sportback has a slightly higher fuel efficiency compared to the A1, making it a more cost-effective option in the long run.
