INTRODUCTION
The Audi A5 Sportback, launched in 2007, filled a niche between the A4 sedan and the A5 coupe, offering a blend of style and practicality. The second-generation F5 model, introduced in 2016, further refined this formula. The 2019 facelift brought updated styling, improved technology, and enhanced efficiency. The 45 TFSI quattro ultra S tronic variant, with its 245 horsepower engine, represented a sweet spot in the lineup, appealing to buyers who desired a spirited driving experience without sacrificing everyday usability. The “45 TFSI” designation doesn’t correlate directly to engine displacement; it’s part of Audi’s naming convention reflecting a position within their performance hierarchy.
Powertrain & Engine Architecture
At the heart of the A5 Sportback 45 TFSI lies the EA888 2.0-liter turbocharged four-cylinder engine, specifically the DKNA engine code. This engine is a direct-injection powerplant featuring an aluminum block and cylinder head. The direct injection system, coupled with a single turbocharger and intercooler, allows for precise fuel delivery and efficient combustion. The engine utilizes a variable valve timing system on both the intake and exhaust sides, optimizing performance across the rev range. The S tronic seven-speed dual-clutch transmission provides rapid and seamless gear changes. The “ultra” designation in “quattro ultra” indicates a demand-responsive all-wheel-drive system. Under normal driving conditions, the system primarily drives the front wheels, engaging the rear wheels only when traction demands it, improving fuel efficiency.
Driving Characteristics
The 245 hp and 272.9 lb-ft of torque delivered by the 2.0-liter engine provide brisk acceleration. The 0-60 mph sprint takes approximately 5.7 seconds, making it a genuinely quick vehicle. The S tronic transmission contributes to this performance with its quick shifts and ability to keep the engine in its optimal power band. Compared to the base 40 TFSI model, the 45 TFSI offers a noticeable performance upgrade. While not as overtly sporty as the S5 models, the 45 TFSI provides ample power for both highway cruising and spirited driving. The quattro all-wheel-drive system provides excellent grip and stability in all weather conditions. The gear ratios are tuned for a balance of acceleration and fuel economy, with a relatively tall seventh gear for efficient highway cruising.
Equipment & Trim Levels
The 45 TFSI quattro ultra S tronic typically came well-equipped as standard. Features included Audi’s MMI infotainment system with a 7-inch touchscreen display (larger screens were optional), 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 Bang & Olufsen sound system, adaptive cruise control, and a panoramic sunroof. Trim levels varied by market, but generally offered packages that added features like upgraded interior trim, sport seats, and exterior styling enhancements.
Chassis & Braking
The A5 Sportback utilizes a sophisticated suspension setup, featuring independent multi-link suspension at both the front and rear. This provides a comfortable ride while maintaining good handling characteristics. The steering is precise and well-weighted, offering a connected feel to the driver. The braking system consists of ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard, along with electronic stability control. The chassis is designed to balance comfort and handling, providing a composed ride even on uneven surfaces.
Market Reception & Comparison
The A5 Sportback 45 TFSI quattro ultra S tronic was generally well-received by automotive critics. It was praised for its stylish design, refined interior, and strong performance. The fuel economy was considered competitive for its class, and the quattro all-wheel-drive system was lauded for its all-weather capability. Compared to the 40 TFSI variant, the 45 TFSI offered a significant performance boost, justifying the higher price tag for many buyers. Against rivals like the BMW 4 Series Gran Coupe and the Mercedes-Benz C-Class Coupe, the A5 Sportback was often seen as offering a more balanced blend of style, practicality, and technology.
Legacy
The EA888 2.0-liter turbocharged engine has proven to be a reliable and durable powerplant, and the S tronic transmission is generally considered robust when properly maintained. The quattro ultra all-wheel-drive system, while efficient, has seen some reports of clutch pack wear under extreme conditions. On the used car market, the A5 Sportback 45 TFSI quattro ultra S tronic holds its value well, thanks to its desirable combination of performance, features, and Audi’s reputation for quality. Regular maintenance, including oil changes and transmission servicing, is crucial to ensure the long-term reliability of this vehicle.
