What are the key differences between the Audi A3 S-Line and the A3 Sportback?

I'm interested in purchasing an Audi A3, but I'm not sure which model to choose. Could someone explain the main differences between the S-Line and Sportback versions?

The Audi A3 S-Line is more focused on performance and handling, with a sport-tuned suspension and enhanced steering control. It also has a more aggressive exterior design. On the other hand, the A3 Sportback offers a more practical and spacious design, with a larger cargo area and more rear legroom. It also has a smoother ride due to its standard suspension.

One key difference between the Audi A3 S-Line and Sportback is the available engine options. The S-Line only offers more powerful engines, such as the 2.0 TFSI or 2.5 TFSI, while the Sportback has a wider range of options, including more fuel-efficient engines such as the 1.5 TFSI.

The A3 S-Line and Sportback also have different exterior and interior styling options. The S-Line has a more sporty and aggressive look, with options for red brake calipers and S-Line badges. The Sportback has a more versatile design, with options for a panoramic sunroof and premium leather seats.
