Powertrain & Engine Architecture
At the heart of the S5 Sedan (B10) 3.0 TFSI lies Audi’s EA839 3.0-liter V6 engine. This engine utilizes a direct injection system, delivering fuel directly into the combustion chambers for improved efficiency and power. The engine is further enhanced by a twin-scroll turbocharger and an intercooler, which minimizes turbo lag and maximizes boost pressure. The valvetrain employs a dual overhead camshaft (DOHC) design with four valves per cylinder, optimizing airflow for increased performance. The engine also incorporates Audi’s Start & Stop system to conserve fuel during idling. The engine is longitudinally mounted in the front of the vehicle, sending power to all four wheels via Audi’s quattro all-wheel-drive system.
The S tronic seven-speed dual-clutch transmission is a key component of the S5’s performance. This transmission offers incredibly fast and smooth gear changes, contributing to the car’s quick acceleration. Unlike a traditional automatic transmission with a torque converter, the S tronic uses two separate clutches – one for odd-numbered gears and one for even-numbered gears – allowing for pre-selection of the next gear, resulting in near-instantaneous shifts. The transmission is electronically controlled and offers both automatic and manual shift modes.
Driving Characteristics
The 362 horsepower and 405.66 lb.-ft. of torque produced by the 3.0 TFSI engine, combined with the quick-shifting S tronic transmission and quattro all-wheel drive, deliver exhilarating performance. Acceleration from 0 to 60 mph is achieved in just 4.3 seconds, and the car feels responsive and eager in all driving situations. The quattro system provides excellent traction, particularly in inclement weather, and allows the S5 to confidently navigate corners. The S tronic transmission’s gear ratios are tuned for both acceleration and fuel efficiency, providing a balance between performance and economy. Compared to the base A5 models, the S5 offers a significantly more engaging driving experience, with sharper throttle response and more powerful acceleration. While not as raw or visceral as some rear-wheel-drive performance sedans, the S5 provides a refined and capable driving experience.
Equipment & Trim Levels
The S5 Sedan (B10) 3.0 TFSI quattro S tronic typically comes well-equipped with standard features including leather upholstery, a panoramic sunroof, a premium sound system, and a suite of advanced driver-assistance systems. Interior trim options include brushed aluminum or carbon fiber accents. Optional extras often include upgraded leather packages, a head-up display, and adaptive cruise control. The S5’s interior is designed with a focus on luxury and technology, offering a comfortable and refined cabin experience.
Chassis & Braking
The S5 Sedan features an independent multi-link suspension at both the front and rear, providing a comfortable ride and precise handling. The suspension is often equipped with adaptive dampers, allowing the driver to adjust the ride quality to suit their preferences. A transverse stabilizer bar is fitted at both ends to reduce body roll during cornering. The braking system consists of ventilated discs at all four wheels, with larger front discs (360mm) compared to the standard A5. The anti-lock braking system (ABS) is standard, providing enhanced braking performance and stability.
Market Reception & Comparison
The Audi S5 Sedan (B10) 3.0 TFSI quattro S tronic was generally well-received by automotive critics, who praised its powerful engine, quick transmission, and all-weather capability. Fuel economy was considered reasonable for a performance sedan of its class, achieving around 22 US mpg in combined driving. Compared to competitors like the BMW M340i and Mercedes-AMG C43, the S5 offered a slightly more understated and refined driving experience. Reliability reports have been generally positive, with the EA839 engine proving to be a durable and dependable unit.
Legacy
The Audi S5 Sedan (B10) 3.0 TFSI quattro S tronic represents a compelling blend of performance, luxury, and technology. The EA839 engine, coupled with the S tronic transmission and quattro all-wheel drive, has proven to be a reliable and capable powertrain. On the used car market, these models hold their value well, attracting buyers who appreciate their performance credentials and Audi’s reputation for quality and refinement. The B10 generation S5 continues to be a popular choice for enthusiasts seeking a sporty and sophisticated sedan.
