Technical Specifications

INTRODUCTION

The Audi A4 (B8 8K) facelift, launched in late 2011, brought revised styling, updated technology, and refined engine options to Audi’s popular compact executive sedan. The 3.0 TFSI V6 quattro S tronic model, introduced in February 2012, represented the performance pinnacle of the range, combining a potent supercharged V6 engine with Audi’s renowned quattro all-wheel-drive system and a quick-shifting seven-speed S tronic dual-clutch transmission. This variant was positioned as a premium offering, appealing to drivers who desired a blend of luxury, performance, and all-weather capability. It competed directly with models like the BMW 335i xDrive and the Mercedes-Benz C350 4MATIC.

Powertrain & Engine Architecture

At the heart of the A4 3.0 TFSI was the CMUA engine, a 2,995 cc (182.77 cu. in.) 60-degree V6. This engine utilized a mechanically driven supercharger in addition to direct fuel injection, providing instant throttle response and a broad torque curve. The supercharger was engaged at lower engine speeds, supplementing the engine’s output before handing over to the turbocharger at higher RPMs. This configuration resulted in a peak output of 272 horsepower at 4,780-6,500 rpm and 400 Nm (295 lb-ft) of torque available from 2,150-4,780 rpm. The engine featured a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The S tronic seven-speed dual-clutch transmission offered rapid, seamless gear changes and contributed to the car’s overall performance. This transmission featured a multi-plate wet clutch and allowed for both fully automatic operation and manual gear selection via steering wheel-mounted paddles.

Driving Characteristics

The 3.0 TFSI quattro S tronic A4 delivered a noticeably more engaging driving experience than its four-cylinder counterparts. The supercharged V6 provided strong acceleration, with a 0-60 mph time of around 5.1 seconds. The S tronic transmission’s quick shifts and the quattro all-wheel-drive system’s excellent traction allowed for confident cornering and acceleration in various conditions. While not as overtly sporty as some rear-wheel-drive competitors, the A4 offered a balanced and refined driving experience. The gear ratios were tuned to provide a good balance between acceleration and fuel efficiency, with the transmission holding gears longer in sport mode to maximize performance. Compared to the 2.0 TFSI models, the 3.0 TFSI offered significantly more power and torque, resulting in a more effortless driving experience, particularly during highway overtaking.

Equipment & Trim Levels

The 3.0 TFSI quattro S tronic typically came well-equipped as standard. Features included leather upholstery, three-zone automatic climate control, a premium sound system, and Audi’s Multi Media Interface (MMI) infotainment system with a central display screen. Optional extras included navigation, a panoramic sunroof, adaptive cruise control, and advanced driver-assistance systems. Trim levels varied slightly by market, but generally offered options for upgraded interior materials, exterior styling enhancements, and additional technology features. The Prestige package, for example, often included features like a Bang & Olufsen sound system, advanced parking assistance, and ventilated front seats.

Chassis & Braking

The A4 B8 8K featured a sophisticated chassis design. The front suspension utilized a multi-link setup, while the rear employed a trapezoidal link configuration. This provided a good balance between ride comfort and handling precision. The quattro all-wheel-drive system distributed power between the front and rear axles as needed, enhancing traction and stability. Braking duties were handled by ventilated discs at the front and solid discs at the rear. The anti-lock braking system (ABS) and electronic stability control (ESC) were standard features, providing enhanced safety and control. The suspension was tuned to complement the car’s performance capabilities, offering a firm but comfortable ride.

Market Reception & Comparison

The Audi A4 3.0 TFSI quattro S tronic was generally well-received by automotive critics. It was praised for its powerful engine, refined transmission, and all-weather capability. However, some reviewers noted that the ride could be firm on certain road surfaces. Compared to the 2.0 TFSI models, the 3.0 TFSI offered a significant performance upgrade, but at a higher price point. Fuel economy was also slightly lower, averaging around 29 US mpg in combined driving. The 3.0 TFSI was often seen as a more compelling alternative to the BMW 335i xDrive, offering a similar level of performance with a more luxurious interior and a more user-friendly infotainment system.

Legacy

The CMUA engine, while complex, proved to be relatively reliable when properly maintained. Common issues included carbon buildup on the intake valves (a characteristic of direct-injection engines) and occasional supercharger failures. The S tronic transmission also required regular maintenance, including fluid changes, to ensure optimal performance and longevity. Today, the A4 3.0 TFSI B8 8K remains a desirable used car, offering a compelling combination of performance, luxury, and all-wheel-drive capability. Well-maintained examples command a premium price in the used car market, and are sought after by enthusiasts who appreciate the car’s refined driving experience and potent powertrain.
