INTRODUCTION
The Audi A5 Coupe (F5) underwent a significant facelift in 2019, bringing with it updated styling, enhanced technology, and refined powertrain options. The 40 TDI variant, introduced in August 2020, was a key component of this refresh. It slotted into the A5 lineup as a compelling alternative to the more powerful 45 TDI and petrol-powered models, targeting buyers who prioritized fuel economy and a comfortable driving experience without sacrificing Audi’s signature refinement. Built on the Volkswagen Group’s MLB Evo platform (shared with models like the Audi A4, VW Passat, and Skoda Superb), the F5 A5 aimed to improve upon the already successful first-generation model in terms of space, weight reduction, and overall driving dynamics.
Powertrain & Engine Architecture
At the heart of the A5 40 TDI lies the Volkswagen Group’s 2.0-liter inline-four diesel engine, designated the DTPA. This engine benefits from a turbocharger and direct injection, producing 204 horsepower at 3800-4200 rpm and a substantial 400 Nm (295 lb-ft) of torque between 1750 and 3250 rpm. The engine incorporates a common rail diesel injection system operating at extremely high pressures to optimize combustion efficiency and reduce emissions. Crucially, this variant features a 48-volt mild hybrid system. This system utilizes a belt starter generator (BSG) and a small lithium-ion battery to enable features like extended start-stop operation, coasting with the engine switched off, 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. The transmission’s gear ratios are tuned to maximize fuel economy while still providing adequate acceleration in everyday driving situations.
Driving Characteristics
The A5 40 TDI with the S tronic transmission delivers a refined and comfortable driving experience. While not as overtly sporty as higher-powered A5 variants, the 204 hp and 400 Nm of torque provide ample power for confident overtaking and cruising. The S tronic transmission shifts quickly and seamlessly, and the quattro all-wheel-drive system provides excellent traction in all weather conditions. The mild hybrid system is largely imperceptible to the driver, working in the background to improve fuel economy. Compared to a manual transmission version (if available in certain markets), the S tronic offers greater convenience, particularly in urban traffic. Against the more powerful 45 TDI, the 40 TDI feels less urgent in its acceleration, but the difference is often negligible in real-world driving. The focus is more on relaxed, effortless progress.
Equipment & Trim Levels
The A5 40 TDI typically came well-equipped as standard, reflecting Audi’s premium positioning. Standard features generally included Audi’s MMI infotainment system with a touchscreen 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 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 upgrades in interior materials, exterior styling, and the availability of additional technology features.
Chassis & Braking
The A5 Coupe’s chassis features a sophisticated multi-link suspension setup at both the front and rear, providing a comfortable ride and precise handling. The suspension is tuned to balance comfort and control, offering a good compromise for everyday driving. The quattro all-wheel-drive system distributes power between the front and rear axles as needed, enhancing traction and stability. Braking duties are handled by ventilated discs at the front and solid discs at the rear, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, further enhancing safety.
Market Reception & Comparison
The Audi A5 40 TDI was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and sophisticated interior. Fuel economy was a particular strength, making it an attractive option for drivers who cover long distances. Compared to the more powerful 45 TDI, the 40 TDI offered a more affordable entry point into the A5 range, while still delivering a premium driving experience. Its main competitors included the BMW 4 Series Coupe and the Mercedes-Benz C-Class Coupe, both of which offered similar levels of performance and luxury.
Legacy
The 2.0-liter TDI engine with the S tronic transmission has proven to be a reliable and durable powertrain in numerous Volkswagen Group vehicles. While diesel engines have faced increased scrutiny in recent years, the DTPA engine, when properly maintained, is known for its longevity. On the used car market, the A5 40 TDI represents a good value proposition, offering a blend of style, comfort, and efficiency. However, potential buyers should be aware of the importance of regular maintenance, particularly regarding the diesel particulate filter (DPF) and the mild hybrid system components.
