The 2018 Audi A4 Premium Plus S Line represents a compelling intersection of refined performance, sophisticated design, and accessible luxury. This specific trim level sits strategically within the A4 lineup, offering a significant step up from the Premium variant while remaining more focused and driver-oriented than the flagship Premium Plus models. For buyers in the market for a compact executive sedan in 2018, this model presented a near-ideal balance of everyday usability, engaging dynamics, and high-end features without venturing into the territory of the more expensive S models.
The S Line Aesthetic: Defining the Look
The primary visual identifier for this trim is the S Line kit, which transforms the standard Premium Plus appearance with a more aggressive and athletic stance. Gloss black trim replaces the standard chrome accents on the front grille, window surrounds, and mirror caps, creating a stark and modern contrast. The S Line sports bumpers, with their larger air intakes and integrated front lip, anchor the front end, while the signature S Line rear diffuser and dual exhaust tips complete the assertive profile. This aesthetic package is not merely cosmetic; it signals a performance-oriented mindset that permeates the driving experience.
Performance and Driving Dynamics
Under the hood, the 2018 A4 Premium Plus S Line was most commonly paired with a turbocharged 2.0-liter four-cylinder engine producing 248 horsepower and 273 lb-ft of torque. This powerplant, mated to a smooth seven-speed S tronic dual-clutch automatic transmission and Quattro all-wheel drive, delivers a driving experience that is both confident and engaging. The steering feels more direct, the suspension tuned for a slightly firmer, more responsive ride, and the overall chassis control inspires confidence through corners. This setup transforms the A4 from a comfortable cruiser into a sedan that genuinely excites its driver, without crossing into the harshness sometimes found in sport-tuned rivals.
Interior Comfort and Technological Features
Inside, the Premium Plus S Line continued Audi’s commitment to a driver-focused cockpit, elevated by premium materials and meticulous craftsmanship. The available 12.3-inch virtual cockpit display was a standout feature, providing crisp, customizable digital gauges for vital vehicle information. The supportive, bolstered front seats, often finished in premium leather, offered excellent comfort for both short commutes and long journeys. High-quality materials were evident throughout, with soft-touch plastics, brushed aluminum accents, and available wood veneers contributing to a cabin that feels sophisticated and well-built rather than merely expensive.
