What does the 'S line' designation on an Audi A4 mean?

I see some Audi A4 models with the 'S line' designation, but I'm not sure what it means. Could you explain its significance?

The 'S line' designation on an Audi A4 means that it has sportier styling and performance upgrades compared to the standard A4 models. This includes a more aggressive body kit, larger wheels, and a sport-tuned suspension. It's a great option for those looking for a more dynamic driving experience.

The 'S line' designation also includes interior upgrades such as sport seats and steering wheel, as well as additional technology features. It's a good choice if you want a more luxurious and high-tech driving experience.
