What is the difference between Audi A4 S line and S4 trim levels?

I am trying to choose between the Audi A4 S line and S4 trim, but I'm not sure what the main differences are. Can anyone explain?

The main difference between the Audi A4 S line and S4 trim levels is their performance capabilities. The S4 trim comes with a more powerful engine, larger brakes, and a sport-tuned suspension for an overall more thrilling driving experience. If you prioritize speed and agility, the S4 trim is the way to go.

Although both the Audi A4 S line and S4 trim levels offer a sportier appearance and upgraded interior features, the S4 takes it a step further with unique styling elements and premium materials. If you want a more luxurious and eye-catching vehicle, go with the S4 trim.

One major difference between the Audi A4 S line and S4 trim levels is the availability of all-wheel drive. The S4 comes standard with Audi's Quattro all-wheel drive system, while the S line only offers it as an optional upgrade. For added traction and control, the S4 may be the better choice for you.
