INTRODUCTION
The Audi S4 (B8, facelift) 3.0 TFSI quattro S tronic, produced between 2011 and 2014, represents the pinnacle of performance within the B8 S4 generation. Positioned as the flagship trim, it offered a substantial upgrade over the standard A4 and the earlier S4 variants. Built on the Volkswagen Group’s B8 platform – also underpinning the Audi A4, A5, and Q5 – the S4 aimed to deliver a compelling blend of everyday usability and exhilarating performance. The facelift brought revised styling, updated technology, and, crucially, the refined 3.0-liter supercharged V6 engine paired exclusively with the seven-speed S tronic dual-clutch transmission and Audi’s quattro all-wheel-drive system.
Powertrain & Engine Architecture
At the heart of the S4 (B8 facelift) lies the EA837 3.0-liter V6 engine, designated as the CGWC, CGXC, or CTUB depending on specific regional calibrations. This engine is characterized by its supercharger, which provides instant boost and eliminates turbo lag, resulting in a linear power delivery. The engine utilizes direct fuel injection (FSI) and a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder. Peak power of 333 horsepower is achieved between 5,500 and 6,500 rpm, while a robust 440 Nm (324.53 lb-ft) of torque is available from 2,900 to 5,300 rpm. The S tronic seven-speed dual-clutch transmission offers incredibly fast and smooth gear changes, contributing to the car’s impressive acceleration. Unlike some competitors that offered manual transmission options, the facelifted S4 was exclusively available with the S tronic.
Driving Characteristics
The combination of the supercharged V6 and the S tronic transmission delivers a remarkably responsive driving experience. Acceleration from 0 to 60 mph takes approximately 4.8 seconds, and the car feels significantly faster in real-world driving conditions. The S tronic’s quick shifts and the engine’s readily available torque contribute to effortless overtaking and a generally engaging driving feel. Compared to earlier S4 models with manual transmissions, the S tronic version offers a more refined and accessible performance profile, prioritizing ease of use and consistent acceleration. While some purists might miss the engagement of a manual gearbox, the S tronic’s speed and efficiency are undeniable. The quattro all-wheel-drive system provides excellent traction in all weather conditions, enhancing stability and confidence.
Equipment & Trim Levels
The S4 (B8 facelift) came generously equipped as standard. Interior features typically included sport seats upholstered in Milano leather, a three-spoke multifunction steering wheel, and brushed aluminum interior trim. The MMI infotainment system with a 6.5-inch display was standard, offering navigation, Bluetooth connectivity, and audio controls. Optional extras included a Bang & Olufsen sound system, advanced driver-assistance systems (such as adaptive cruise control and blind-spot monitoring), and various exterior styling packages. The S4’s interior was designed to strike a balance between sporty aesthetics and luxurious comfort.
Chassis & Braking
The S4 (B8 facelift) featured a sport-tuned suspension with stiffer springs and dampers compared to the standard A4. The front suspension utilized a multi-link design, while the rear employed a trapezoidal link setup. Larger ventilated disc brakes were fitted at all four corners, providing ample stopping power. The braking system was enhanced with ABS (Anti-lock Braking System) and electronic brake-force distribution. The chassis was designed to minimize body roll and maximize cornering stability, contributing to the car’s dynamic handling characteristics.
Market Reception & Comparison
The Audi S4 (B8 facelift) was generally well-received by automotive critics. It was praised for its potent engine, refined transmission, and all-weather capability. Compared to its rivals, such as the BMW 335i and the Mercedes-Benz C350, the S4 offered a unique blend of performance and practicality. Fuel economy was respectable for a performance sedan, averaging around 29 US mpg in combined driving. Reliability was generally good, although some owners reported minor issues with the supercharger and the S tronic transmission. The S4’s quattro all-wheel-drive system was a significant advantage in regions with inclement weather.
Legacy
The Audi S4 (B8 facelift) 3.0 TFSI quattro S tronic remains a desirable used car today. Its combination of performance, luxury, and technology has ensured its continued appeal to enthusiasts. The 3.0 TFSI engine, while requiring regular maintenance (particularly regarding the supercharger), is generally considered robust. The S tronic transmission, if properly maintained, can provide years of reliable service. The B8 S4 facelift represents a sweet spot in the S4 lineage, offering a compelling package for those seeking a high-performance, all-weather sedan.
