Technical Specifications

INTRODUCTION

The Audi S4 Avant (B9, facelift 2019) 3.0 TFSI V6 (354 Hp) quattro tiptronic is a performance-oriented station wagon that debuted as part of the B9 S4’s mid-life refresh. The facelift, introduced in 2019 for the 2020 model year, brought subtle styling updates, enhanced technology, and crucially, revisions to the engine management system to meet stricter emissions standards. This variant, equipped with the 3.0-liter turbocharged V6 and an eight-speed tiptronic automatic transmission, was a mainstay of the S4 Avant range, offering a balance between exhilarating performance and everyday usability. It competed directly with rivals like the BMW M340i Touring and the Mercedes-AMG C43 Estate.

Powertrain & Engine Architecture

At the heart of the S4 Avant is the EA839 3.0-liter V6 engine, designated as the CWGD code. 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 help to manage heat and boost performance. The valvetrain employs a dual overhead camshaft (DOHC) configuration with four valves per cylinder, optimizing airflow for increased power output. The 354 horsepower peak is achieved between 5400 and 6400 rpm, while the substantial 500 Nm (368.78 lb-ft) of torque is available from a low 1370 rpm all the way to 4500 rpm. The eight-speed tiptronic automatic transmission is a torque-converter type, offering smooth and relatively quick shifts. It features a manual shift mode for greater driver control.

Driving Characteristics

The 3.0 TFSI V6 with the tiptronic transmission delivers a refined and potent driving experience. While not as overtly aggressive as a dual-clutch transmission, the tiptronic provides smooth gear changes and contributes to the S4 Avant’s comfortable ride quality. Acceleration from 0 to 60 mph takes approximately 4.7 seconds, making it a genuinely quick vehicle. Compared to the six-speed manual transmission available on some S4 models, the tiptronic prioritizes ease of use and comfort over outright driver engagement. The quattro all-wheel-drive system provides excellent traction in all weather conditions, enhancing stability and confidence. The gear ratios are tuned to provide strong acceleration in everyday driving situations, with the eighth gear offering relaxed cruising at highway speeds.

Equipment & Trim Levels

The S4 Avant (B9, facelift 2019) 3.0 TFSI V6 quattro tiptronic typically came well-equipped as standard. Interior features included sport seats upholstered in a combination of leather and Alcantara, a flat-bottomed steering wheel, and brushed aluminum trim. The infotainment system featured a 10.1-inch touchscreen display with Audi’s MMI touch response system. 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, adaptive cruise control, and a head-up display. Exterior features typically included S-specific styling cues, such as a unique grille, bumpers, and exhaust outlets.

Chassis & Braking

The S4 Avant features a sophisticated suspension system designed to balance performance and comfort. The front suspension utilizes a five-link independent setup with a transverse stabilizer bar, while the rear employs a multi-link independent suspension, also with a stabilizer bar. This configuration minimizes body roll and provides precise handling. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The ABS (Anti-lock Braking System) is standard, enhancing safety and control during emergency braking situations. The chassis is reinforced compared to the standard A4 Avant to handle the increased power and torque.

Market Reception & Comparison

The S4 Avant (B9, facelift 2019) 3.0 TFSI V6 quattro tiptronic was generally well-received by automotive critics. It was praised for its powerful engine, comfortable ride, and practical wagon body style. The tiptronic transmission was sometimes criticized for not being as engaging as a manual or dual-clutch transmission, but its smoothness and ease of use were appreciated by many drivers. Compared to the 2.0-liter four-cylinder models, the V6 offered a significant performance upgrade. Fuel economy, while respectable for a performance vehicle, was lower than that of the four-cylinder variants. Reliability has been generally good, although some owners have reported issues with the carbon buildup on the intake valves, a common issue with direct-injection engines.

Legacy

The Audi S4 Avant (B9, facelift 2019) 3.0 TFSI V6 quattro tiptronic remains a desirable used car option. The EA839 engine, while requiring periodic carbon cleaning, is generally robust and capable of high mileage. The tiptronic transmission is known for its durability. The combination of performance, practicality, and Audi’s build quality ensures that these wagons continue to hold their value. As a performance wagon, it represents a sweet spot in the market, offering a compelling alternative to SUVs and crossovers.
