Audi S4 S Tronic: 2025 Review, Performance And Practicality

The Audi S4 S Tronic stands out as a compelling choice in the compact executive sports sedan segment, offering a harmonious mix of potent acceleration, sophisticated all-wheel-drive dynamics, and premium interior refinement. Powered by a turbocharged 3.0-liter V6 engine producing 349 horsepower and 369 lb-ft of torque, this model pairs its robust output with a lightning-quick seven-speed S Tronic dual-clutch transmission and Audi’s renowned quattro system, making it equally adept at highway cruising and twisty backroad sprints.

Engine and Transmission: Effortless Power Delivery

At the heart of the S4 lies its turbocharged V6, a unit that delivers smooth, linear power across a broad rev range. Peak torque arrives early at around 1,750 rpm and holds steady up to 5,000 rpm, ensuring strong low-end pull for overtaking and merging without drama. The engine’s hot-V configuration places the turbocharger between the cylinder banks, minimizing lag and sharpening throttle response compared to traditional setups. This results in a 0-60 mph sprint in approximately 4.5 seconds, with a top speed electronically limited to 155 mph.

The star of the powertrain is undoubtedly the S Tronic seven-speed dual-clutch gearbox. It shifts with remarkable speed and precision, whether in automatic Drive or Sport modes, or via intuitive steering-wheel paddles. Reviewers praise its ability to predict driver intent, making manual interventions rare even during aggressive driving. In everyday scenarios, it enables relaxed open-road efficiency, with figures dipping below 8 liters per 100 km (around 29 mpg) when driven judiciously. The transmission integrates seamlessly with the quattro system, distributing power optimally for traction in varied conditions.

Chassis Dynamics: Precision Meets Comfort

The S4’s chassis benefits from a sport-tuned suspension that’s stiffer and 23 mm lower than the standard A4, yet remarkably compliant. Standard adaptive dampers offer Comfort, Auto, Dynamic, and Individual modes via Audi Drive Select, allowing tailoring of steering, throttle, and damping. In Comfort, it soaks up urban potholes with poise; switch to Dynamic, and body roll tightens while maintaining ride quality that’s usable daily.

Steering is a highlight for many, providing accurate weighting and feedback that inspires confidence through corners. The quattro all-wheel-drive system, with its 40/60 front/rear torque bias and optional sport differential featuring torque vectoring, delivers neutral handling and exceptional grip. Unlike predecessors prone to understeer, the S4 feels agile and planted, with minimal dive under braking and tenacious cornering adhesion. Brakes are firm and progressive, though some note an initial abruptness that requires modulation.

Interior Refinement and Practicality

Step inside, and the S4 envelops occupants in Audi’s signature luxury. The cabin boasts high-quality materials, logical ergonomics, and a driver-focused cockpit. Physical climate controls are intuitive, while the infotainment system—featuring a 10.1-inch touchscreen and virtual cockpit digital gauges—responds swiftly. Front seats are supportive with ample adjustability, though rear space is tighter than rivals, accommodating adults for short trips comfortably.

• Key Interior Features: Nappa leather options, heated/ventilated seats, ambient lighting, Bang & Olufsen audio.
• Cargo Space: Sedan offers 13 cubic feet; Avant wagon expands to 46.9 cu ft with seats folded.
• Tech Highlights: Apple CarPlay/Android Auto, adaptive cruise, lane-keeping assist.

Noise insulation is exemplary, with tire roar and wind hushed even at motorway speeds. Build quality feels bulletproof, contributing to the S4’s reputation as a long-term companion.

Fuel Efficiency and Running Costs

Despite its performance credentials, the S4 impresses with real-world economy. Combined figures hover around 25-30 mpg, improving to mid-30s on highways. CO2 emissions sit at approximately 180-190 g/km, positioning it favorably against thirstier rivals. Maintenance follows Audi’s premium schedule, but quattro reliability and efficient powertrain keep ownership costs manageable for the class.

Safety and Driver Assistance

Audi equips the S4 with a comprehensive suite of active safety tech. Standard features include pre-sense front, adaptive cruise control with traffic jam assist, and side assist. Crash test ratings from Euro NCAP and IIHS underscore its structural integrity, with five-star overall scores. The all-wheel-drive system enhances stability in adverse weather, making it a safe family hauler.
