Powertrain & Engine Architecture
At the heart of the A4 allroad 45 TFSI lies the EA888 2.0-liter turbocharged four-cylinder engine, specifically the DMTA variant. This engine is a direct-injection powerplant featuring an aluminum block and head. The DMTA version benefits from a twin-scroll turbocharger, enhancing responsiveness and minimizing turbo lag. The engine utilizes a port and direct injection system, combining the benefits of both technologies for improved efficiency and reduced emissions. The 48-volt mild hybrid system incorporates a belt starter generator (BSG) and a small lithium-ion battery. This system allows for extended start-stop functionality, regenerative braking, and a slight power boost during acceleration. The seven-speed S tronic dual-clutch transmission provides rapid and smooth gear changes, contributing to both performance and efficiency. This transmission features a wet clutch design for improved durability and heat dissipation.
Driving Characteristics
The 265 horsepower and 272.9 lb.-ft. of torque delivered by the 45 TFSI engine provide brisk acceleration. The 0-60 mph sprint is achieved in approximately 5.5 seconds. The S tronic transmission’s quick shifts and the engine’s broad torque curve make for a responsive driving experience. Compared to the lower-powered 40 TFSI variant, the 45 TFSI offers a noticeable performance upgrade, while remaining more accessible and fuel-efficient than the higher-performance S4 model. The quattro all-wheel-drive system provides excellent traction in various weather conditions, enhancing stability and confidence. The allroad’s raised suspension provides a more comfortable ride on uneven surfaces, although it does introduce a slightly higher center of gravity compared to the standard A4 Avant.
Equipment & Trim Levels
The A4 allroad 45 TFSI typically came well-equipped as standard. Features included Audi’s virtual cockpit digital instrument cluster, a touchscreen infotainment system with navigation, leather upholstery, three-zone automatic climate control, and a power liftgate. Standard safety features included Audi pre sense basic, lane departure warning, and automatic emergency braking. Optional extras included a Bang & Olufsen sound system, a head-up display, adaptive cruise control, and a panoramic sunroof. The allroad-specific exterior trim included unique front and rear bumpers, side sills, and wheel arch extensions, giving it a more rugged appearance.
Chassis & Braking
The A4 allroad features a fully independent suspension system, with multi-link setups at both the front and rear. The suspension is tuned to provide a balance between comfort and handling. The allroad’s ride height is approximately 1.5 inches higher than the standard A4 Avant, increasing ground clearance for off-road excursions. Braking duties are handled by ventilated discs at all four corners. The quattro all-wheel-drive system utilizes a self-locking center differential to distribute torque between the front and rear axles as needed. Electronic stability control (ESC) and anti-lock brakes (ABS) are standard features.
Market Reception & Comparison
The A4 allroad 45 TFSI was generally well-received by automotive critics. It was praised for its blend of practicality, performance, and all-weather capability. Compared to the 40 TFSI variant, the 45 TFSI offered a significant performance boost without a substantial penalty in fuel economy. The mild hybrid system contributed to improved fuel efficiency, although the gains were relatively modest. The A4 allroad competed with other premium wagons, such as the Volvo V60 Cross Country and the BMW 3 Series Touring xDrive. The Audi offered a more refined interior and a more sophisticated driving experience than some of its rivals.
Legacy
The EA888 2.0-liter turbocharged engine has proven to be a reliable and durable powerplant, although preventative maintenance, particularly oil changes, is crucial. The S tronic transmission is generally reliable, but dual-clutch transmissions can be more expensive to repair than traditional automatic transmissions. The 48-volt mild hybrid system has also proven to be relatively trouble-free. On the used car market, the A4 allroad 45 TFSI holds its value well, due to its desirable combination of features and performance. It remains a popular choice for buyers seeking a versatile and capable premium wagon.
