2019 Audi S5 Horsepower: Engine Output and Performance Specs

2019 Audi S5 Horsepower at a Glance

The 2019 Audi S5 is powered by a 3.0-liter supercharged and turbocharged V6 engine that produces 354 horsepower and 369 pound-feet of torque. That output is channeled through a seven-speed dual-clutch transmission and Audi's quattro all-wheel-drive system. In the sedan body style, the S5 reaches 60 mph in about 4.4 seconds, while the coupe and convertible variants run a few tenths slower depending on conditions and driver inputs.

Engine Details and Technology

The 3.0 TFSI V6 uses a combination of mechanical supercharging and turbocharging to deliver broad torque across the rev range. Audi's valvelift system varies intake valve lift to improve airflow at higher engine speeds. The single-scroll turbocharger and supercharger work in sequence, with the supercharger providing low-end response and the turbo taking over as boost builds. This setup helps the S5 produce its peak torque figure from roughly 2,900 rpm through to about 5,300 rpm, with horsepower peaking near 5,600 rpm.

Power Delivery and Transmission

Audi routes the engine's output through a seven-speed S tronic dual-clutch gearbox. The transmission uses two clutches to pre-select gears, allowing near-instant shifts without interrupting power flow. Drivers can choose between automatic upshifts or manually select gears using paddle shifters. The quattro system normally sends power to the rear wheels under normal conditions, but can vector torque frontward when traction is lost, helping the S5 maintain composure during cornering and acceleration.

Performance in Different Body Styles

The 2019 S5 lineup includes a four-door sedan, a two-door coupe and a two-door convertible. All three share the same 354-horsepower powertrain, but their curb weights differ. The sedan is the lightest of the trio, followed by the coupe, with the convertible weighing the most due to its folding canvas roof structure. These weight differences translate to small but measurable variations in acceleration and handling feel.

Real-World Driving Considerations

In everyday driving, the 2019 S5's 354 horsepower provides confident highway merging and overtaking without the need to downshift aggressively. The engine remains relatively composed during low-speed cruising, though the dual-clutch transmission can exhibit slight hesitation at very low speeds in stop-and-go traffic. The S5's sport exhaust, standard on most trims, allows the V6 to produce a more pronounced sound under hard acceleration, which some drivers prefer for its auditory feedback.

Fuel Economy and Practicality

Audi rated the 2019 S5 at 18 mpg in the city and 28 mpg on the highway for the sedan. Actual figures vary based on driving style, traffic conditions and whether the vehicle is operated in its more efficient front-wheel-drive mode or the default quattro configuration. The S5's fuel tank holds 17.4 gallons, giving it a theoretical range of over 400 miles on a full tank under mixed driving conditions.

How the 2019 S5 Compares

At 354 horsepower, the 2019 Audi S5 sits between the base Audi A5, which produces 248 horsepower, and the higher-performance RS5, which produces 444 horsepower. The S5's output is competitive within its segment, matching or exceeding the BMW M440i's 382 horsepower figure in the sedan while offering standard all-wheel drive. The Mercedes-AMG C43, by comparison, produces 362 horsepower, though it uses a different turbocharged V6 configuration.

Maintenance and Longevity

The 2019 S5's 3.0 TFSI engine uses a timing belt that requires replacement at intervals specified by Audi, typically around 90,000 miles. The supercharger and turbocharger are designed for the engine's expected service life, but drivers who regularly push the engine to its redline may notice increased wear on the dual-clutch transmission's clutch packs over time. Regular oil changes using the recommended specification help maintain the engine's stated output over the long term.
