Powertrain & Engine Architecture
At the heart of the A5 Sportback 45 TFSI lies the DMTA engine, a 2.0-liter inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and is coupled with a single twin-scroll turbocharger and an intercooler to enhance power and efficiency. The engine’s output of 265 horsepower at 5250-6500 rpm and 370 Nm (272.9 lb-ft) of torque between 1600-4500 rpm is achieved through precise engine management and optimized combustion. The ‘45 TFSI’ designation doesn’t directly correlate to engine displacement; it’s part of Audi’s naming convention indicating a performance level within their model range. Crucially, this variant incorporates a 48-volt mild hybrid system. This system features a belt starter generator (BSG) that enables features like extended engine-off coasting, smoother start-stop operation, and a slight power boost during acceleration. The seven-speed S tronic dual-clutch transmission provides rapid and seamless gear changes, contributing to both performance and fuel economy. The transmission’s quick shift times and efficient power delivery complement the engine’s characteristics.
Driving Characteristics
The 265 hp and 370 Nm of torque, combined with the quattro all-wheel-drive system, deliver a responsive and confident driving experience. Acceleration from 0 to 60 mph is achieved in approximately 5.3 seconds, making it a brisk performer. The S tronic transmission’s programming prioritizes smooth shifts in normal driving modes, but can be adjusted to more aggressive settings via Audi’s drive select system. Compared to the base A5 models with lower-powered engines, the 45 TFSI offers a noticeable improvement in acceleration and overall responsiveness. While not as overtly sporty as the S5, it provides ample power for everyday driving and spirited weekend excursions. The mild hybrid system contributes to improved fuel economy, particularly in urban environments, without significantly impacting performance. The quattro system ensures excellent traction in various weather conditions, enhancing stability and control.
Equipment & Trim Levels
The A5 Sportback 45 TFSI typically came standard with features such as Audi’s MMI touch response infotainment system with a 10.1-inch touchscreen display, Audi virtual cockpit (digital instrument cluster), leather upholstery, three-zone automatic climate control, and a suite of driver-assistance systems including lane departure warning and front collision warning. Optional extras included features like a Bang & Olufsen sound system, adaptive cruise control, a head-up display, and various interior trim upgrades. Trim levels varied slightly by market, but generally offered packages that bundled popular options together. The Sportback body style itself offered enhanced practicality compared to the A5 Coupe, with its five doors and larger rear seating area.
Chassis & Braking
The A5 Sportback 45 TFSI utilizes an independent multi-link suspension system at both the front and rear axles. This suspension setup provides a comfortable ride quality while maintaining good handling characteristics. The suspension is tuned to balance comfort and control, offering a composed ride even on uneven surfaces. Braking duties are handled by ventilated discs at all four corners. The braking system is responsive and provides ample stopping power. The quattro all-wheel-drive system actively distributes torque between the front and rear axles, optimizing traction and stability. The vehicle’s weight distribution is carefully managed to enhance handling balance.
Market Reception & Comparison
The A5 Sportback 45 TFSI was generally well-received by automotive critics. Reviewers praised its blend of performance, efficiency, and technology. The mild hybrid system was noted as a positive addition, contributing to improved fuel economy without compromising driving enjoyment. Compared to the 2.0 TFSI models with lower horsepower outputs, the 45 TFSI offered a significant performance upgrade. Against competitors like the BMW 4 Series Gran Coupe and Mercedes-Benz C-Class Coupe, the A5 Sportback 45 TFSI was often seen as a strong contender, offering a compelling combination of style, practicality, and driving dynamics. Fuel economy figures of around 34.6 – 32.7 US mpg combined were competitive within its segment.
Legacy
The Audi A5 Sportback (F5) 45 TFSI represents a key step in Audi’s transition towards electrification and improved fuel efficiency. The integration of the 48-volt mild hybrid system demonstrated Audi’s commitment to reducing emissions and enhancing performance. The DMTA engine, while not without its complexities, has proven to be a relatively reliable unit when properly maintained. On the used car market, these models are generally sought after for their balance of performance, features, and practicality. Regular maintenance, including oil changes and adherence to Audi’s recommended service intervals, is crucial for ensuring the long-term reliability of the engine and transmission. The A5 Sportback’s enduring popularity is a testament to its well-rounded design and engaging driving experience.
