The Audi A4 40 TFSI S tronic, produced from 2018 to 2019, represents a significant iteration of the B9 (8W) generation A4, following the model’s facelift. Positioned as a mid-range offering within the A4 lineup, this variant aimed to balance performance, fuel efficiency, and technology, appealing to a broad spectrum of buyers in the premium compact executive car segment. It served as a key model in Audi’s European and North American markets, offering a compelling alternative to rivals like the BMW 3 Series and Mercedes-Benz C-Class. The “40 TFSI” designation, part of Audi’s revised naming scheme, indicates a power output level rather than engine displacement, and in this case, signifies a 2.0-liter turbocharged four-cylinder engine producing 190 horsepower.

INTRODUCTION
The Audi A4 40 TFSI S tronic, launched as part of the B9 facelift in 2018, built upon the success of its predecessor, offering a refined and technologically advanced package. This variant was designed to appeal to buyers seeking a balance between performance and efficiency, making it a popular choice in the competitive compact executive segment. The facelift brought subtle styling updates, enhanced technology, and improved engine efficiency. The 40 TFSI model, with its 2.0-liter turbocharged engine and seven-speed S tronic dual-clutch transmission, represented a sweet spot in the A4 range, offering a more engaging driving experience than the lower-powered options while remaining more accessible than the higher-performance S4.
Powertrain & Engine Architecture
At the heart of the A4 40 TFSI lies the EA888 2.0-liter inline-four cylinder engine, specifically the DKYA or DLVA engine code depending on the market. This engine utilizes direct fuel injection and a single turbocharger with an intercooler to deliver a potent combination of power and efficiency. The engine benefits from Audi’s innovative valve lift technology (Audi Valve Lift System – AVLS) which allows for variable valve lift on the intake side, optimizing performance and fuel economy across a wider range of engine speeds. The S tronic seven-speed dual-clutch transmission provides rapid and seamless gear changes, contributing to the car’s responsive driving characteristics. This transmission offers both automatic and manual shift modes, allowing drivers to tailor the driving experience to their preferences. The engine is longitudinally mounted, driving the front wheels in the standard configuration.
Driving Characteristics
The A4 40 TFSI S tronic delivers a refined and engaging driving experience. The 190 horsepower and 320 Nm (236 lb-ft) of torque provide ample power for everyday driving and confident overtaking maneuvers. The S tronic transmission contributes to brisk acceleration, with a 0-60 mph time of around 6.9 seconds. While not as overtly sporty as the S4, the 40 TFSI offers a well-balanced chassis and precise steering, making it enjoyable to drive on winding roads. The transmission’s gear ratios are optimized for both acceleration and fuel efficiency, providing a smooth and responsive driving experience in various conditions. Compared to the manual transmission versions, the S tronic offers quicker shifts and greater convenience, although some purists may prefer the greater control of a manual gearbox.
Equipment & Trim Levels
The A4 40 TFSI S tronic typically came well-equipped as standard. Features included Audi’s MMI infotainment system with a 7-inch touchscreen display (upgradeable to a larger screen), Audi Virtual Cockpit (digital instrument cluster) as an option, three-zone automatic climate control, and a suite of driver-assistance systems such as lane departure warning and automatic emergency braking. Interior upholstery was typically cloth or leather, with a range of color options available. Optional extras included a premium sound system, navigation system, panoramic sunroof, and various styling packages. Trim levels varied slightly depending on the market, but generally offered increasing levels of luxury and technology.
Chassis & Braking
The A4 40 TFSI S tronic features a sophisticated chassis designed to provide a comfortable and controlled ride. The front suspension utilizes MacPherson struts, while the rear suspension employs a multi-link setup. This configuration provides excellent handling and stability. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, enhancing safety and driver confidence. The suspension tuning is geared towards comfort, but still provides a reasonably sporty driving experience.
Market Reception & Comparison
The Audi A4 40 TFSI S tronic was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, comfortable ride, and high-quality interior. Fuel economy was also a strong point, with combined fuel consumption figures ranging from 5.8 to 5.9 l/100 km. Compared to the lower-powered A4 variants, the 40 TFSI offered a noticeable performance upgrade without significantly compromising fuel efficiency. Compared to the higher-output models, it provided a more affordable entry point into the A4 range. Reliability reports have generally been positive, with the EA888 engine proving to be a durable and dependable unit.
Legacy
The Audi A4 40 TFSI S tronic remains a popular choice in the used car market. Its combination of performance, efficiency, and technology continues to appeal to buyers seeking a premium compact executive car. The EA888 engine is known for its reliability and relatively low maintenance costs, making it a practical choice for long-term ownership. While newer A4 models offer even more advanced features and technology, the B9 8W facelifted version, particularly the 40 TFSI S tronic, represents a well-rounded and highly capable vehicle that continues to hold its value.
