INTRODUCTION
The Audi A4 Avant (B9 8W) 2.0 TDI 122 hp S tronic, launched in 2016, is a front-wheel-drive station wagon that forms part of the fifth generation (B9) A4 series. Built on the Volkswagen Group’s MLB Evo platform (shared with models like the VW Passat and Skoda Superb), the B9 Avant aimed to offer a more sophisticated and technologically advanced experience than its predecessor. This particular variant, powered by a 2.0-liter turbocharged diesel engine producing 122 horsepower, was designed to appeal to buyers prioritizing fuel economy and practicality without sacrificing the Audi brand’s reputation for quality and refinement. It served as a key model in European markets, where diesel station wagons remain highly popular.
Powertrain & Engine Architecture
At the heart of the A4 Avant 2.0 TDI 122 hp S tronic lies the Volkswagen Group’s DEUC engine. This is a 1968cc, inline-four cylinder diesel engine featuring common rail direct injection and a turbocharger with an intercooler. The engine utilizes a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing gas flow for improved efficiency and power delivery. The DEUC engine is known for its relatively quiet operation and good low-end torque. The 122 hp output is achieved at 3500-4000 rpm, while peak torque of 270 Nm (199 lb-ft) is available from 1500-3000 rpm. This broad torque curve contributes to the engine’s usability in everyday driving situations.
The “S tronic” designation refers to Audi’s dual-clutch transmission (DCT), a seven-speed automatic gearbox. This transmission offers quick and smooth gear changes, enhancing both performance and fuel efficiency. Unlike traditional torque converter automatics, 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 virtually seamless shifts. The transmission is electronically controlled and features a sport mode for more aggressive shifting.
Driving Characteristics
The 122 hp 2.0 TDI S tronic A4 Avant delivers a comfortable and refined driving experience. While not particularly sporty, the engine provides sufficient power for everyday driving and highway cruising. Acceleration from 0-62 mph takes approximately 10.6 seconds, and the top speed is 198 km/h (123 mph). The S tronic transmission contributes to a responsive feel, and the broad torque band means that overtaking maneuvers can be executed with relative ease. Compared to the more powerful 150 hp or 190 hp TDI variants, this version feels less urgent, but it offers a more relaxed and fuel-efficient driving experience. The front-wheel-drive configuration provides good traction in most conditions, although it can exhibit some torque steer under hard acceleration.
Equipment & Trim Levels
The A4 Avant 2.0 TDI 122 hp S tronic typically came equipped with a respectable level of standard features. These included Audi’s MMI infotainment system with a 7-inch display screen, Bluetooth connectivity, automatic climate control, and a leather-wrapped multifunction steering wheel. Safety features such as ABS, electronic stability control, and multiple airbags were also standard. Higher trim levels offered options such as a larger MMI display, navigation system, upgraded audio system, leather upholstery, and various driver assistance systems like adaptive cruise control and lane departure warning. Interior upholstery was typically cloth in the base models, with leather available as an upgrade.
Chassis & Braking
The B9 A4 Avant features a sophisticated chassis design. Both front and rear suspension utilize a multi-link setup, providing a good balance between ride comfort and handling. The front suspension incorporates aluminum subframes to reduce weight and improve rigidity. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard, enhancing safety in emergency braking situations. The car’s weight of around 1525 kg (3362 lbs) is relatively moderate for a station wagon of its size, contributing to its manageable handling characteristics.
Market Reception & Comparison
The Audi A4 Avant 2.0 TDI 122 hp S tronic was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined interior. However, some reviewers noted that the engine lacked the outright performance of its more powerful siblings. Compared to the 150 hp TDI variant, the 122 hp version offered lower running costs but at the expense of acceleration and overall driving excitement. Against competitors like the BMW 3 Series Touring and Mercedes-Benz C-Class Estate, the A4 Avant was seen as a strong contender, offering a compelling combination of practicality, luxury, and technology.
Legacy
The 2.0 TDI engine, in various iterations, has proven to be a reliable and durable powertrain. While early versions of the engine were subject to some issues with diesel particulate filter (DPF) clogging, later models, including the DEUC engine found in the B9 A4 Avant, are generally considered to be more robust. On the used car market, the A4 Avant 2.0 TDI 122 hp S tronic represents a good value proposition, offering a well-built and practical station wagon at a reasonable price. Regular maintenance, including timely oil changes and DPF servicing, is crucial to ensure the long-term reliability of this powertrain.
