The 2019 Audi S4 represents a significant moment in the evolution of the compact luxury performance segment, blending turbocharged efficiency with the raw power traditionally found in larger sports sedans. This specific model year, positioned as the final year of the B8 platform generation before the shift to the B9, offered drivers an exhilarating balance of everyday usability and track-focused capability. Understanding the true output and real-world performance of the 2019 Audi S4 requires looking beyond the official horsepower figures to appreciate the engineering intent and driving dynamics.
Defining the Performance: Horsepower and Engineering
At the heart of the 2019 Audi S4 lies its 3.0-liter turbocharged V6 engine, a technological marvel that delivers a compelling mix of efficiency and brute force. While official specifications from Audi typically cite a figure of 349 horsepower and 369 pound-feet of torque, the reality of how this power is delivered creates an experience that feels significantly more dynamic. This 2.0T engine, badged as a V6 through Audi’s innovative use of an electrically driven compressor, provides immediate throttle response and a linear power curve that makes the S4 feel far more potent than its displacement might suggest.
Power Delivery and the Quattro System
The true magic of the S4 is not just in the number of horses, but in how that power is distributed. The legendary Quattro all-wheel-drive system is the perfect partner for the turbocharged V6, transforming the 349 hp into confident acceleration in any weather condition. Power is sent to all four wheels, with a sophisticated multi-plate clutch actively managing torque distribution between the front and rear axles. This setup not only enhances grip during hard acceleration but also contributes to a stable and planted feeling at higher speeds, making the S4 feel like a grand tourer rather than just a fast sedan.
Performance Metrics and Real-World Driving
When evaluating the 2019 Audi S4’s performance, 0 to 60 mph times are often the first metric considered. Independent tests and manufacturer data place the figure at an impressive range of 4.6 to 4.9 seconds, a testament to the effectiveness of the powertrain and traction management. This acceleration feels explosive yet controlled, with the engine note rising in a mechanical crescendo that is signature to Audi’s high-performance engines. The S4 transforms from a comfortable cruiser into a formidable performer with a mere turn of the throttle.
Official Horsepower: 349 hp @ 5,400 – 6,400 rpm
Official Torque: 369 lb-ft @ 1,300 – 4,300 rpm
0-60 mph: Approximately 4.6 – 4.9 seconds
Top Speed: Electronically limited to 155 mph (250 km/h)
Drivetrain: Quattro all-wheel drive
Transmission: 7-speed S tronic dual-clutch automatic
The Role of the S-Tronic Transmission
Paired exclusively with the engine is the seven-speed S tronic dual-clutch transmission, a component that elevates the driving experience to another level. This transmission is designed for lightning-fast shifts, often occurring in milliseconds, which results in a seamless surge of power without the interruption of a traditional automatic gearbox. The driver can manually control shifts via paddles behind the steering wheel, allowing for a more engaging and sporty driving style that perfectly complements the S4’s performance capabilities.
