The 2019 Audi RS 5 represents the pinnacle of the B8 platform, blending a naturally aspirated V8 with Quattro all-wheel drive to deliver a driving experience that is both refined and aggressively responsive. Under the hood lies the heart of this performance coupe, a 2.9-liter twin-turbocharged V8 that generates 444 horsepower and 443 lb-ft of torque, mated to a seven-speed S tronic dual-clutch transmission. This powertrain configuration allows the RS 5 to sprint from 0 to 60 mph in just 3.9 seconds, a testament to Audi’s engineering prowess in balancing daily usability with track-focused capability.
The 2.9-Liter Twin-Turbocharged V8: Power and Precision
At the core of the 2019 RS 5 is the 2.9-liter twin-turbocharged V8 engine, a unit developed jointly by Audi and Porsche. This compact yet robust powertrain features two turbochargers positioned between the cylinder banks, a configuration that minimizes lag and provides immediate power delivery across the rev range. The engine utilizes a cylinder deactivation system known as Active Cylinder Management, which shuts down four cylinders during light-load conditions to improve fuel efficiency without compromising the premium feel of the drive.
One of the standout characteristics of this engine is its linear power curve. Unlike many turbocharged engines that deliver a sudden surge of power, the RS 5’s V8 builds momentum smoothly, making it ideal for both highway merging and spirited back-road carving. The integration of the turbochargers with the engine’s lightweight forged internals allows for a peak power output of 444 hp at 6,500 rpm, with maximum torque arriving between 2,500 and 4,500 rpm, a range that covers most driving scenarios.
Quattro All-Wheel Drive and the S tronic Transmission
Paired with the powerful V8 is the Quattro all-wheel-drive system, which ensures optimal traction and stability in various driving conditions. The system uses a Torsen-based center differential that continuously distributes power between the front and rear wheels, dynamically adjusting based on grip and steering input. This setup not only enhances cornering confidence but also allows the RS 5 to maintain composure in adverse weather, a crucial factor for a performance vehicle.
The transmission of choice is the seven-speed S tronic dual-clutch automatic, known for its rapid shift speeds and efficiency. The gearbox is calibrated to prioritize responsiveness, with sharp, decisive shifts that make the power delivery feel immediate and seamless. Drivers can manually select gears using paddles mounted behind the steering wheel, adding an engaging layer of control that enthusiasts appreciate during spirited drives.
Performance Dynamics and Handling Characteristics
Suspension and Chassis Engineering
The chassis of the 2019 RS 5 is engineered to complement the high-revving engine and sophisticated drivetrain. It features a five-link front suspension and a multi-link rear setup, both crafted from lightweight aluminum to reduce unsprung mass. Adaptive air suspension is available as an option, allowing drivers to adjust the ride height and damping characteristics to suit either comfort or sport mode.
Steering is precise and weighted, providing excellent feedback without being overly fatiguing during long drives. The turn-in is sharp, and the car follows the driver’s inputs with minimal body roll, thanks in part to the optional dynamic package that includes larger brakes and enhanced sway bars. This combination of setup and technology results in a driving dynamics package that feels balanced and planted at high speeds.
Braking and High-Speed Stability
Performance brakes are essential for a car of this caliber, and the RS 5 does not disappoint. Standard equipment includes large ventilated disc brakes with red-painted calipers, while the optional performance package upgrades to ceramic composite brakes for improved heat dissipation and fade resistance. These braking systems inspire confidence when approaching high-speed corners or making emergency stops, especially on winding mountain roads.
