INTRODUCTION
The Audi A5 Coupe (F5) 40 TDI quattro S tronic, launched in 2018, is a two-door, four-seater coupe built on the MLB Evo platform, also known as the A5 (F5) platform. This generation represented a significant evolution for the A5, boasting a more refined design, advanced technology, and improved efficiency compared to its predecessor. The ‘40 TDI’ designation signifies the engine’s power output within Audi’s naming convention, indicating a diesel engine producing approximately 190 horsepower. The ‘quattro’ label denotes Audi’s renowned all-wheel-drive system, and ‘S tronic’ refers to Audi’s dual-clutch transmission (DCT).
Powertrain & Engine Architecture
At the heart of the A5 40 TDI lies the 2.0-liter four-cylinder diesel engine, specifically utilizing the DESA or DETA engine code depending on the exact production date and market. This engine is a turbocharged common-rail direct injection diesel, known for its balance of power and fuel efficiency. The engine features a single turbocharger with an intercooler to enhance performance. The common-rail system delivers fuel at extremely high pressure, optimizing combustion and reducing emissions. The engine also incorporates advanced technologies like variable valve timing and a particulate filter to meet stringent Euro 6d-TEMP emission standards. The seven-speed S tronic dual-clutch transmission provides rapid and smooth gear changes, contributing to both performance and efficiency. This transmission is known for its quick shifts and ability to anticipate the driver’s needs.
Driving Characteristics
The 190 hp and 400 Nm (295 lb-ft) of torque delivered by the 40 TDI powertrain provide a comfortable and capable driving experience. While not as overtly sporty as higher-performance A5 variants, the 40 TDI offers ample power for everyday driving and highway cruising. Acceleration from 0 to 60 mph takes around 7 seconds, and the car feels responsive in most situations. The S tronic transmission contributes to a seamless power delivery, and the quattro all-wheel-drive system provides excellent traction in all weather conditions. Compared to the manual transmission options, the S tronic offers convenience and slightly quicker acceleration, though some enthusiasts may prefer the greater driver engagement of a manual gearbox. The 40 TDI’s power delivery is characterized by strong low-end torque, making it easy to navigate city streets and overtake slower traffic.
Equipment & Trim Levels
The A5 40 TDI quattro S tronic typically came well-equipped as standard. Features included Audi’s MMI infotainment system with a 7-inch display (larger screens were available as options), 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 (a fully digital instrument cluster), a Bang & Olufsen sound system, adaptive cruise control, and various styling packages. Interior trim levels varied, with options for different wood or aluminum inlays. The standard seats provided good support and comfort, and optional sport seats were available for a more aggressive feel.
Chassis & Braking
The A5 Coupe features a sophisticated chassis design with independent multi-link suspension at both the front and rear. This setup provides a comfortable ride quality while maintaining good handling characteristics. The quattro all-wheel-drive system distributes power between the front and rear axles as needed, optimizing traction and stability. The braking system consists of ventilated discs at the front and solid discs at the rear, providing ample stopping power. ABS (Anti-lock Braking System) is standard, along with electronic stability control. The steering is precise and well-weighted, offering a good balance of feedback and assistance.
Market Reception & Comparison
The Audi A5 40 TDI quattro S tronic was generally well-received by automotive critics. It was praised for its refined driving experience, fuel efficiency, and luxurious interior. Compared to other A5 variants, the 40 TDI offered a compelling balance of performance and economy. The 1.8 TFSI petrol models were less powerful but more affordable, while the higher-output TDI variants (such as the 50 TDI) offered more performance but at a higher price point. Fuel economy was a key strength of the 40 TDI, consistently achieving around 47-54 mpg in combined driving. Reliability was generally good, although, like all modern diesel engines, the particulate filter could require occasional maintenance.
Legacy
The Audi A5 Coupe (F5) 40 TDI quattro S tronic remains a popular choice in the used car market. The 2.0-liter TDI engine is known for its durability and relatively low running costs, provided it is properly maintained. The S tronic transmission, while generally reliable, may require servicing at higher mileages. Overall, this variant represents a well-rounded and sophisticated coupe that offers a compelling combination of performance, efficiency, and luxury. Its all-wheel-drive system and refined driving experience continue to appeal to buyers seeking a capable and comfortable grand tourer.
