Powertrain & Engine Architecture
The heart of the A5 40 TDI S tronic is the 2.0-liter inline-four cylinder diesel engine, designated as either DESA or DETA depending on minor revisions. This engine utilizes a sophisticated common-rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A turbocharger with an intercooler further enhances performance by forcing more air into the cylinders. The engine produces 190 horsepower at 3800-4200 rpm and a substantial 400 Nm (295 lb-ft) of torque between 1750 and 3000 rpm. This broad torque curve provides strong acceleration in everyday driving situations. The engine also incorporates a diesel particulate filter (DPF) to meet stringent Euro 6d-TEMP emission standards.
Paired with the engine is Audi’s seven-speed S tronic dual-clutch transmission. This transmission offers rapid and smooth gear changes, contributing to both performance and fuel efficiency. The S tronic operates with two separate clutches, pre-selecting the next gear for near-instantaneous shifts. The transmission is front-wheel drive in this configuration, prioritizing efficiency and reducing complexity compared to quattro all-wheel drive models.
Driving Characteristics
The A5 40 TDI S tronic delivers a refined and comfortable driving experience. While not overtly sporty, the 190 hp engine and quick-shifting S tronic transmission provide adequate performance for most drivers. Acceleration from 0 to 60 mph takes approximately 7.3 seconds. The engine’s strong low-end torque makes it easy to navigate city streets and execute overtaking maneuvers. Compared to the more powerful 45 TDI, the 40 TDI feels less urgent, but it offers a more relaxed and fuel-efficient driving experience. Compared to manual transmission versions, the S tronic provides a more effortless driving experience, particularly in stop-and-go traffic.
Equipment & Trim Levels
The A5 40 TDI S tronic 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 display, a Bang & Olufsen sound system, adaptive cruise control, and a panoramic sunroof. Trim levels varied by market, but generally offered options for upgraded interior materials and exterior styling elements.
Chassis & Braking
The A5 Coupe features an independent multi-link suspension at both the front and rear axles, providing a comfortable ride and 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 the front and solid discs at the rear, providing ample stopping power. ABS (Anti-lock Braking System) is standard, enhancing safety and stability during emergency braking situations.
Market Reception & Comparison
The A5 40 TDI S tronic was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, and comfortable ride. Fuel economy was also a strong point, with combined figures ranging from 4.2 to 4.5 l/100 km (56-52.3 US mpg). Compared to the 45 TDI, the 40 TDI offered a more affordable entry point into the A5 Coupe range, while still providing a respectable level of performance and refinement. The 35 TDI offered even better fuel economy but at the expense of power.
Legacy
The 2.0-liter TDI engine and S tronic transmission combination have proven to be remarkably reliable in the A5 Coupe. While diesel particulate filters can require maintenance, the engine itself is generally robust and capable of high mileage. On the used car market, the A5 40 TDI S tronic represents a good value proposition, offering a blend of style, performance, and efficiency. Its reputation for reliability and relatively low running costs makes it a popular choice among buyers seeking a premium coupe.
