What does Audi S line mean?

[McDavid]

Audi S line refers to a style package and not a specific model. The differences between a common A4 S line and a regular A4 are limited to the front grille, front bumper style, side skirt style, trunk style, rear bumper style, and interior wrapped seats. It also includes features like headlight washers, pre-specialization functions, a sporty multifunction steering wheel, and multiple driver information display lights. The Audi A4 is a B-class model manufactured by FAW-Volkswagen. In terms of powertrain, the Audi A4 comes standard with the quattro all-wheel-drive system, which provides double the traction. This system automatically, accurately, and timely distributes the ground force to each wheel when turning or braking on various complex road surfaces, thereby improving the directional stability and traction of the vehicle under complex conditions.
