INTRODUCTION
The Audi A5 Coupe (F5, facelift) 40 TDI S tronic, launched in late 2019, represented a significant update to Audi’s popular mid-size coupe. Falling within the F5 generation (2016-2024), the facelift brought styling revisions, upgraded technology, and refined engine options. The “40 TDI” designation signified a 2.0-liter turbocharged diesel engine producing 190 horsepower, paired with Audi’s seven-speed S tronic dual-clutch transmission. This combination aimed to deliver a balance of performance, fuel economy, and driving comfort, making it a compelling choice for buyers in Europe and other markets where diesel remained prevalent. It sat comfortably in the middle of the A5 Coupe range, offering a step up from the entry-level petrol engines while remaining more accessible than the higher-performance S5 models.
Powertrain & Engine Architecture
At the heart of the A5 40 TDI lies the Volkswagen Group’s 2.0-liter inline-four diesel engine, specifically the DETA or DESA engine code depending on the specific market and emissions regulations. This engine utilizes a common-rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. A single turbocharger with an intercooler provides forced induction, boosting power and torque. The engine features four valves per cylinder and an overhead camshaft (OHC) configuration. The S tronic seven-speed dual-clutch transmission (DCT) is a key component, offering rapid and smooth gear changes. This transmission features two separate clutches, one for odd gears and one for even gears, allowing for pre-selection of the next gear and minimizing interruption in power delivery. The engine also incorporates a particulate filter to reduce emissions, complying with Euro 6 standards.
Driving Characteristics
The 190 hp and 400 Nm (295 lb-ft) of torque delivered by the 40 TDI powertrain provided a respectable driving experience. Acceleration from 0-100 km/h (0-62 mph) took approximately 7.7 seconds. While not a sports car, the engine offered ample low-end torque, making it responsive in everyday driving situations. The S tronic transmission contributed to a smooth and efficient driving experience, with quick shifts and minimal lag. Compared to the higher-output petrol versions of the A5, the 40 TDI prioritized fuel economy and effortless cruising over outright performance. Manual transmission options were available on other A5 variants, but the S tronic was favored by many for its convenience and efficiency. The gear ratios were tuned for a balance between acceleration and fuel efficiency, with taller gears for highway cruising.
Equipment & Trim Levels
The A5 Coupe 40 TDI S tronic typically came well-equipped as standard. Features included Audi’s MMI infotainment system with a touchscreen display, automatic climate control, leather upholstery, and a suite of driver-assistance systems such as lane departure warning and automatic emergency braking. Optional extras included a virtual cockpit (digital instrument cluster), a premium sound system, adaptive cruise control, and various styling enhancements. Trim levels varied by market, but generally offered options for upgraded interior materials, exterior styling packages, and additional technology features. The interior design was typically characterized by Audi’s minimalist aesthetic, with high-quality materials and a focus on ergonomics.
Chassis & Braking
The A5 Coupe’s chassis featured an independent multi-link suspension at both the front and rear, providing a comfortable and controlled ride. The front suspension utilized coil springs and stabilizer bar, while the rear suspension also incorporated a stabilizer bar to reduce body roll. Braking duties were handled by ventilated discs at the front and solid discs at the rear, providing adequate stopping power. The anti-lock braking system (ABS) was standard, enhancing safety and stability. The steering system was a rack-and-pinion setup with electric power assistance, offering precise and responsive steering feel.
Market Reception & Comparison
The Audi A5 Coupe 40 TDI S tronic was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, comfortable ride, and stylish design. Fuel economy was a significant selling point, with combined fuel consumption figures ranging from 4.2 to 4.5 liters per 100 kilometers (56-52.3 US mpg). Compared to the petrol-powered A5 variants, the 40 TDI offered superior fuel efficiency and torque. However, some critics noted that the diesel engine lacked the responsiveness and excitement of the petrol engines. Compared to competitors such as the BMW 4 Series Coupe and Mercedes-Benz C-Class Coupe, the A5 40 TDI offered a compelling combination of performance, luxury, and efficiency.
Legacy
The 2.0-liter TDI engine and S tronic transmission pairing proved to be a reliable combination in the A5 Coupe. While diesel engines have faced increased scrutiny in recent years, these units are generally known for their durability and longevity when properly maintained. On the used car market, the A5 40 TDI S tronic remains a popular choice, offering a good balance of value, performance, and fuel economy. Regular maintenance, including oil changes and filter replacements, is crucial for ensuring the long-term reliability of this powertrain. The A5 Coupe, in general, has established itself as a stylish and well-engineered grand tourer, and the 40 TDI variant continues to appeal to buyers seeking a refined and efficient coupe experience.
