Powertrain & Engine Architecture
At the heart of the A5 45 TFSI lies the EA888 2.0-liter turbocharged inline-four engine, specifically the DKNA variant. This engine is a staple in the Volkswagen Group, known for its responsiveness and efficiency. It utilizes direct fuel injection and an integrated exhaust manifold for improved turbocharger response. The turbocharger itself is a twin-scroll unit, further enhancing low-end torque. The engine produces 245 horsepower at 5000-6500 rpm and 272.9 lb-ft of torque between 1600 and 4300 rpm. This power is delivered to all four wheels via Audi’s ‘quattro ultra’ all-wheel-drive system. This system intelligently switches between front-wheel drive and all-wheel drive as needed, prioritizing fuel efficiency. The ‘S tronic’ 7-speed dual-clutch transmission provides rapid and smooth gear changes, contributing to the car’s overall performance.
Driving Characteristics
The 45 TFSI with the S tronic transmission offers a noticeably more engaging driving experience than the lower-powered A5 variants. Acceleration from 0-60 mph takes approximately 5.7 seconds, making it a genuinely quick car. The S tronic transmission is quick to respond to driver inputs, and the quattro ultra system provides excellent traction in various conditions. While not as overtly sporty as the S5, the A5 45 TFSI strikes a good balance between comfort and performance. The gear ratios are well-chosen for both everyday driving and more spirited excursions. The engine delivers a broad torque band, making overtaking maneuvers effortless. Compared to a manual transmission equipped A5, the S tronic offers convenience and quicker shifts, but some purists might miss the direct connection of a manual gearbox.
Equipment & Trim Levels
The A5 Sportback 45 TFSI quattro ultra 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 touch response system with a 10.1-inch display, a Bang & Olufsen sound system, a panoramic sunroof, and adaptive cruise control. Trim levels varied slightly by market, but generally, the 45 TFSI sat in the mid-range of the A5 Sportback lineup, offering a step up in luxury and technology compared to the base models.
Chassis & Braking
The A5 Sportback features a sophisticated chassis design with independent multi-link suspension at both the front and rear. This setup provides a comfortable ride while maintaining good handling characteristics. The quattro ultra system adds to the car’s stability and cornering ability. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The braking system is responsive and provides ample stopping power. The standard steering system is an electromechanical power steering system, offering precise and well-weighted feel.
Market Reception & Comparison
The Audi A5 Sportback 45 TFSI quattro ultra was generally well-received by automotive critics. It was praised for its stylish design, refined interior, and engaging driving experience. The combination of the 2.0-liter turbo engine, S tronic transmission, and quattro all-wheel drive was considered a sweet spot in the A5 lineup. Compared to the base A5 models, the 45 TFSI offered a significant performance boost. Compared to the S5, it provided a more affordable entry point into the A5 range while still delivering a satisfying driving experience. Fuel economy was respectable for a car of its class, averaging around 36.8 mpg in combined driving.
Legacy
The EA888 engine, in its various iterations, has proven to be a reliable and durable powerplant. The S tronic transmission is also generally considered to be reliable, although regular maintenance is crucial. The quattro ultra system, while efficient, has been known to experience occasional issues with its clutch pack. On the used car market, the A5 Sportback 45 TFSI quattro ultra represents a good value proposition, offering a blend of style, performance, and technology at a reasonable price. With proper maintenance, these vehicles are expected to provide many years of reliable service.
