INTRODUCTION
The Audi S4 (B9 facelift) 3.0 TFSI with the tiptronic transmission represents a refined and potent offering in the luxury sport sedan segment. Building upon the already successful B9 S4, the facelift brought updated styling, enhanced technology, and continued improvements to the powertrain. This variant was positioned as a step up from the base 2.0 TFSI S4, offering significantly more power and a more engaging driving experience. It served as a direct competitor to vehicles like the BMW M340i and Mercedes-AMG C43.
Powertrain & Engine Architecture
At the heart of this S4 variant lies the EA839 3.0-liter V6 engine. This engine utilizes a direct injection fuel system and is force-fed by a twin-scroll turbocharger with an intercooler, resulting in 354 horsepower and 368.78 lb-ft of torque. The engine code CWGD is specific to this output level and configuration. The EA839 engine family is known for its robust construction and ability to handle increased power levels. The eight-speed tiptronic automatic transmission is a torque-converter type, offering smooth and relatively quick shifts. It features a sophisticated control unit that adapts to driving style and conditions. While not as overtly sporty as a dual-clutch transmission, the tiptronic provides a comfortable and refined driving experience, particularly in everyday traffic. The quattro all-wheel-drive system is integral to the S4’s performance, distributing power between the front and rear axles as needed to maximize traction.
Driving Characteristics
The 3.0 TFSI engine paired with the tiptronic transmission delivers a broad and accessible powerband. Peak torque is available from a low 1370 rpm, providing strong acceleration in everyday driving situations. While the 0-60 mph time of around 4.4 seconds is impressive, the tiptronic transmission doesn’t offer the lightning-fast shifts of a dual-clutch unit. Compared to a manual transmission-equipped S4, the tiptronic version feels slightly less engaging, but it compensates with greater ease of use and comfort. The quattro all-wheel-drive system provides exceptional grip, particularly in inclement weather, and contributes to confident handling. The transmission’s gear ratios are tuned for a balance between acceleration and fuel efficiency, with higher gears designed for relaxed highway cruising.
Equipment & Trim Levels
The S4 (B9 facelift) 3.0 TFSI tiptronic typically came well-equipped as standard. Interior features included sport seats upholstered in a combination of leather and Alcantara, a flat-bottom steering wheel, and aluminum trim accents. The MMI touch response system, with its dual touchscreen displays, controlled infotainment and vehicle settings. Standard safety features included Audi pre sense basic, lane departure warning, and automatic emergency braking. Optional extras included a Bang & Olufsen sound system, a virtual cockpit digital instrument cluster, and adaptive cruise control. The S4 also offered a range of exterior customization options, including different wheel designs and paint colors.
Chassis & Braking
The S4’s chassis is designed to provide a balance between comfort and handling. It features a multi-link suspension system at both the front and rear, with coil springs and transverse stabilizers. The suspension is tuned to be firmer than that of a standard A4, providing more controlled body roll and sharper steering response. Braking duties are handled by ventilated discs at all four corners, with larger rotors and more powerful calipers compared to the A4. The ABS (Anti-lock braking system) and electronic stability control systems work in conjunction to provide confident stopping power and maintain control in challenging conditions.
Market Reception & Comparison
The S4 (B9 facelift) 3.0 TFSI tiptronic was generally well-received by automotive critics. It was praised for its powerful engine, comfortable ride, and sophisticated interior. Some reviewers noted that the tiptronic transmission wasn’t as engaging as a manual, but acknowledged its smoothness and ease of use. Compared to the 2.0 TFSI S4, the 3.0 TFSI version offered a significant performance upgrade, justifying the higher price tag for many buyers. Fuel economy was respectable for a performance sedan, averaging around 23.1 US mpg in combined driving. Reliability has been generally good, although some owners have reported minor issues with the infotainment system.
Legacy
The Audi S4 (B9 facelift) 3.0 TFSI tiptronic has established itself as a desirable used car. The EA839 engine has proven to be durable and reliable when properly maintained. The tiptronic transmission, while not the most exciting option for driving enthusiasts, is known for its longevity. As these vehicles age, regular maintenance, including oil changes and timing belt replacements, is crucial to ensure continued reliability. The S4’s blend of performance, luxury, and practicality continues to appeal to buyers seeking a well-rounded sport sedan.
