The 2014 Audi A4 Quattro S Line represents a significant moment in the evolution of the compact luxury sedan, blending the accessible performance of the Premium Plus trim with the distinct visual language of the S Line package. This specific model year offered drivers the opportunity to experience the responsive Quattro all-wheel-drive system, typically reserved for the higher-performance models, wrapped in a more aggressive and sporty exterior design. The S Line package was not merely cosmetic; it signaled a shift in handling dynamics and road presence, making the standard A4 feel more dynamic and connected to the road.
Design and Exterior Refinements
Visually, the 2014 A4 Quattro S Line is distinguished by a series of design cues that move it away from the conservative Premium Plus model. The front fascia receives a more assertive treatment, featuring larger single-frame grille with an aluminum finish and prominent chrome accents. This is complemented by unique LED daytime running lights and slightly larger air dams, which contribute to a more sophisticated and athletic stance. The overall effect is a vehicle that appears wider and more planted, signaling its enhanced performance capabilities without resorting to the overt aggression of the true S models.

The profile of the sedan is enhanced by the S Line body kit, which includes subtle side skirts and a more pronounced rear diffuser. These elements work in concert to streamline airflow, reducing drag while enhancing the visual width of the car. Completing the exterior transformation are the 18-inch alloy wheels, often in a striking 5-arm design that provides a perfect balance of elegance and sportiness. Inside, the driver is greeted by a cabin meticulously crafted with premium materials, where the S Line branding is present on the sport seats and steering wheel, a testament to the interior sport package that defines this trim level.
Performance and Driving Dynamics
Under the hood, the 2014 A4 Quattro S Line typically mated the 2.0-liter turbocharged four-cylinder engine, producing 211 horsepower and 258 lb-ft of torque, to the Quattro all-wheel-drive system. This powertrain combination delivers a compelling driving experience, providing confident acceleration in all weather conditions. The Quattro system, with its Torsen center differential, intelligently distributes power between the front and rear wheels, enhancing traction and stability during cornering and inclement weather. This setup transforms the A4 from a comfortable cruiser into a engaging sports sedan that feels secure and planted through demanding road surfaces.
Interior Comfort and Technology
The interior of the 2014 A4 Quattro S Line is a sanctuary of German engineering, prioritizing driver engagement and passenger comfort. The sport seats, bolstered with additional side bolsters, provide excellent lateral support during spirited driving without sacrificing everyday comfort. The steering wheel is adjustable and features paddle shifters, allowing for seamless manual gear changes that put the driver in direct control of the powertrain. High-quality materials, such as premium leather and brushed aluminum accents, are prevalent throughout the cabin, creating an atmosphere of refined sophistication that is characteristic of the Audi brand.
Technology is seamlessly integrated into the dashboard, centered around the MMI infotainment system. This interface provides intuitive control over navigation, audio, and vehicle settings. The available Bang & Olufsen premium audio system further elevates the experience, delivering crystal-clear sound that fills the cabin without distortion, even at higher volumes. Advanced safety features, including blind-spot monitoring, rear cross-traffic alert, and adaptive cruise control, were often bundled in the Technology package, ensuring that the vehicle was as smart as it was fast.
