The Audi A5 Sportback (F5) 45 TFSI S tronic, produced primarily for the 2019 model year, represents a compelling blend of performance and practicality within the fifth generation (F5) A5 Sportback lineup. Positioned as a mid-range offering, it slotted between the entry-level 40 TFSI models and the more potent S5 variants. This particular configuration, combining a 2.0-liter turbocharged four-cylinder engine with Audi’s seven-speed S tronic dual-clutch transmission, aimed to deliver a refined driving experience with respectable fuel economy. The Sportback body style, a five-door fastback, offered increased versatility compared to the A5 Coupe and Cabriolet, making it a popular choice in European markets where practicality is highly valued. While sold in limited numbers in the US, it primarily targeted buyers seeking a premium, sporty vehicle with everyday usability.

Powertrain & Engine Architecture
At the heart of the A5 Sportback 45 TFSI lies the EA888 2.0-liter inline-four cylinder engine, specifically the DKNA variant. This engine is a staple in the Volkswagen Group’s product lineup, known for its blend of performance and efficiency. It utilizes direct fuel injection, delivering fuel directly into the combustion chamber for improved combustion efficiency and reduced emissions. A single twin-scroll turbocharger, coupled with an intercooler, provides forced induction, boosting power output. The engine also features variable valve timing on both the intake and exhaust sides, optimizing performance across the rev range. The seven-speed S tronic dual-clutch transmission is a key component, offering rapid and seamless gear changes. This transmission features two separate clutches, one for odd-numbered gears and one for even-numbered gears, allowing for pre-selection of the next gear and minimizing interruption in power delivery.
Driving Characteristics
The 245 horsepower and 272.9 lb-ft of torque produced by the 45 TFSI powertrain translate to brisk acceleration. The 0-60 mph sprint takes approximately 6.2 seconds, and the car feels responsive in everyday driving situations. The S tronic transmission contributes to a smooth and engaging driving experience, with quick shifts and minimal torque interruption. Compared to the more powerful S5 models, the 45 TFSI offers a more balanced driving experience, prioritizing comfort and fuel efficiency over outright performance. While the manual transmission option (available in some markets) provided a more direct connection to the engine, the S tronic offered convenience and ease of use, particularly in urban environments. The gear ratios are tuned for a balance between acceleration and fuel economy, with taller gearing in higher gears for efficient cruising.
Equipment & Trim Levels
The A5 Sportback 45 TFSI typically came well-equipped as standard. Features included Audi’s MMI infotainment system with a 7-inch 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 larger MMI display, a Bang & Olufsen sound system, a panoramic sunroof, and adaptive cruise control. Trim levels varied by market, but generally offered options for upgraded interior materials, exterior styling enhancements, and additional technology features. The Sportback’s interior was characterized by Audi’s typically high build quality and attention to detail, creating a premium and comfortable cabin environment.
Chassis & Braking
The A5 Sportback 45 TFSI utilizes a sophisticated chassis design featuring independent multi-link suspension at both the front and rear. This suspension setup provides a comfortable ride while maintaining good handling characteristics. The front suspension incorporates anti-roll bars to reduce body roll during cornering. Braking duties are handled by ventilated discs at the front and solid discs at the rear, providing ample stopping power. The car is equipped with ABS (Anti-lock Braking System) and electronic stability control as standard, enhancing safety and control. The steering is a rack-and-pinion system with electric power assistance, offering precise and responsive steering feel.
Market Reception & Comparison
The A5 Sportback 45 TFSI was generally well-received by automotive critics. It was praised for its stylish design, comfortable ride, and refined powertrain. The S tronic transmission was lauded for its smooth and quick shifts. Compared to the 40 TFSI models, the 45 TFSI offered a noticeable performance upgrade, while remaining more affordable than the S5 variants. Fuel economy was considered competitive for its class, with combined fuel consumption figures ranging from 35.6 to 37.3 US mpg. Reliability was generally good, although some owners reported minor issues with the infotainment system.
Legacy
The Audi A5 Sportback 45 TFSI S tronic, while not a high-volume seller in all markets, has established a reputation as a well-rounded and reliable vehicle. The EA888 engine has proven to be durable and relatively easy to maintain, and the S tronic transmission, while requiring periodic servicing, is generally considered robust. On the used car market, these models hold their value reasonably well, attracting buyers who appreciate the combination of style, performance, and practicality. The F5 generation A5 Sportback, including the 45 TFSI variant, represents a significant step forward in terms of technology and refinement, solidifying Audi’s position as a leading premium automotive brand.
