INTRODUCTION
The Audi A4 allroad 45 TFSI quattro ultra S tronic, launched in 2019 as part of the B9 facelift, builds upon the A4 allroad’s established formula of offering wagon practicality with enhanced off-road capability. The “allroad” designation signifies a model line within the A4 range specifically designed for those seeking a vehicle that can handle more than just paved roads. This particular variant, with its 245 horsepower engine and sophisticated all-wheel-drive system, aimed to provide a compelling alternative to traditional SUVs, offering a more engaging driving experience and a lower center of gravity. It slots into the A4 allroad lineup above the 40 TFSI models and below the more performance-oriented S4 allroad (where available).
Powertrain & Engine Architecture
At the heart of the A4 allroad 45 TFSI lies the EA888 2.0-liter turbocharged four-cylinder engine, specifically coded DKNA. This engine utilizes direct fuel injection and an integrated exhaust manifold to improve thermal efficiency and responsiveness. The turbocharger, an evolution of the twin-scroll design, minimizes turbo lag and delivers strong torque across a broad rev range. The engine produces 245 horsepower at 5000-6500 rpm and 370 Nm (272.9 lb-ft) of torque between 1600 and 4300 rpm. The S tronic seven-speed dual-clutch transmission provides rapid and smooth gear changes, contributing to both performance and fuel efficiency. The quattro ultra system is a demand-based all-wheel-drive system. Under normal driving conditions, the system primarily drives the front wheels, disconnecting the rear axle to save fuel. When traction is needed, an electronically controlled multi-plate clutch engages the rear wheels, distributing torque as required.
Driving Characteristics
The A4 allroad 45 TFSI offers a refined and capable driving experience. The 245 hp engine provides ample power for everyday driving and confident overtaking maneuvers. The S tronic transmission shifts quickly and decisively, enhancing the sense of responsiveness. While not as overtly sporty as the S4 allroad, the 45 TFSI delivers a pleasing balance between performance and comfort. The quattro ultra system provides excellent traction in various conditions, inspiring confidence on slippery surfaces. Compared to the lower-powered 40 TFSI variants, the 45 TFSI offers noticeably stronger acceleration and a more relaxed cruising experience. The gear ratios are tuned for a blend of fuel efficiency and performance, with a relatively tall seventh gear for highway cruising.
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 Apple CarPlay and Android Auto integration, leather upholstery, three-zone automatic climate control, and a power liftgate. The allroad-specific exterior trim included unique front and rear bumpers, side sills, and wheel arch extensions, giving it a more rugged appearance. Optional extras included a panoramic sunroof, a premium sound system, adaptive cruise control, and a head-up display. Interior color options typically included black, gray, and tan leather combinations.
Chassis & Braking
The A4 allroad features a sophisticated suspension system designed to provide both comfort and handling. The front suspension utilizes a multi-link setup, while the rear also employs a multi-link design. This configuration allows for precise wheel control and a smooth ride. The standard brakes consist of ventilated discs on all four wheels, providing ample stopping power. The allroad models typically feature a slightly raised ride height compared to the standard A4 wagon, providing increased ground clearance for off-road excursions. Stabilizer bars are fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The A4 allroad 45 TFSI was generally well-received by automotive critics. It was praised for its refined driving experience, spacious interior, and all-weather capability. Compared to the 40 TFSI version, the 45 TFSI offered a significant performance upgrade without sacrificing fuel economy. While the BMW 3 Series Touring and Mercedes-Benz C-Class Estate were direct competitors, the A4 allroad distinguished itself with its standard all-wheel drive and slightly more rugged character. Fuel economy figures of 7.4-7.6 l/100 km (31.8-30.9 US mpg) were considered competitive for its class. Reliability reports have generally been positive, with the EA888 engine proving to be a durable and dependable unit.
Legacy
The A4 allroad 45 TFSI quattro ultra S tronic represents a well-rounded and capable premium wagon. The EA888 engine and S tronic transmission have proven to be reliable and relatively easy to maintain. On the used car market, these models hold their value reasonably well, reflecting their build quality and desirable features. While newer models with more advanced technology have since been introduced, the B9 A4 allroad 45 TFSI remains a compelling option for buyers seeking a versatile and refined all-weather vehicle.
