Here are the specific differences: Exterior differences: The Audi S4 model is an upgraded version based on the standard Audi A4. In terms of appearance, the S4 inherits the design language of the A4L, featuring Audi's latest family-style design with matrix LED headlights. The body side lines are relatively smooth, while the S4 incorporates numerous sporty elements such as large-sized alloy wheels, red brake calipers, and a black front grille. The rear features LED taillights, and the exhaust system follows Audi's S-series design with a quad-tailpipe layout, giving it an overall sporty feel. Key details include the S4's signature "silver mirrors" (a hallmark of Audi's sport series), with some special editions using carbon fiber mirrors—neither of which is available on the standard A4L. The S4 also bears an "S4" logo on the front grille and features larger front air intakes. Some special editions even come with darkened headlight clusters. Engine differences: The Audi A4L offers two engine options: a 1.4T and a 2.0T four-cylinder, with horsepower ranging between 150-190. In contrast, the S4, as the sportier variant of the A4L, is equipped with a 3.0T V6 engine producing 354 horsepower. The difference between a four-cylinder and a six-cylinder engine directly results in a significant performance gap between the A4L and S4.

I noticed the exterior differences between the Audi A4L and S4 are quite striking. Starting with the front fascia: The S4 features a more aggressive front grille with bolder honeycomb mesh and large lower air intakes, giving it an ultra-fierce look, while the A4L maintains a smoother, more elegant profile with flowing lines. For wheels, the S4 comes standard with 19-inch rims in dynamic multi-spoke designs, whereas the A4L typically uses more practical 17-inch wheels with a relatively conservative appearance. Moving to the rear, the S4 boasts signature quad exhaust tips paired with a sporty rear diffuser, looking incredibly stylish, while the A4L has either hidden or dual exhaust outlets for a more understated, practical vibe. Dimensionally, the A4L is slightly longer due to its extended wheelbase, better suited for family space needs, while the S4 has a more compact, sporty stance. Details-wise, the S4 adds matte silver side mirrors and an S4 badge on the rear, with an overall design language that’s more bold and expressive, ensuring high road presence. These differences stem from their positioning: the S4 follows a performance-oriented approach, while the A4L prioritizes comfort and convenience. Switching from an A4L to an S4 instantly makes you feel that cool factor, though maintenance costs for the S4 are higher due to pricier parts.

I noticed that the main differences between the A4L and S4 exteriors lie in the front fascia, wheels, and rear end. The A4L's front design is more minimalist, with finer grille mesh and smoother bumper lines, making it suitable for daily commuting. In contrast, the S4 features a large honeycomb grille and enlarged air intakes, creating a sporty and aggressive look. For the wheels, the S4 typically comes with 19-inch sporty rims featuring sharp edges and unique styling, while the A4L often opts for 17-inch standard wheels prioritizing practicality. The exhaust system on the S4 has a quad-outlet design with chrome accents for a bold visual impact, whereas the A4L has either dual or single exhaust outlets with a more understated hidden design. In terms of body length, the A4L is slightly longer by a few dozen millimeters due to its extended wheelbase, enhancing rear passenger space, while the S4 is more compact for stronger handling dynamics. Detailing-wise, the S4 features metallic-finish side mirrors and red 'S4' badging at the rear, while the A4L uses standard black lettering. Overall, the S4 exudes a more performance-oriented and flamboyant style suited for spirited driving, whereas the A4L leans toward family comfort with a subdued visual presence. When choosing between them, consider budget—the S4 is significantly pricier—and how the aesthetic differences translate to distinct experiences, including potential subtle optimizations like headlight clusters. Daily maintenance for the S4 may also be costlier due to more wear-prone exterior parts and the added complexity of its design.

I noticed that the exterior comparison between the Audi A4L and S4 highlights many subtle differences. In terms of the front fascia, the S4 features a larger grille and more exaggerated lower air intakes, giving it a more aggressive look, while the A4L has a smoother design. The S4 comes standard with 19-inch wheels in a dynamic, petal-like design, whereas the A4L often has smaller, more practical-sized wheels. At the rear, the S4 stands out with its eye-catching quad exhaust pipes, while the A4L opts for a more understated and reserved exhaust design. The A4L has a slightly longer body, offering more practical space, while the S4’s compact dimensions emphasize agility. Details like the S4’s silver mirror caps and unique badging further distinguish it from the A4L’s more conventional treatment. Overall, the S4 is the cooler choice, perfect for those seeking individuality.
