INTRODUCTION
The Audi A5 Cabriolet (F5) 40 TDI quattro S tronic, launched in 2018, is a four-seater, two-door convertible based on the Volkswagen Group’s MLB Evo platform (specifically the A5/B9 platform). This generation A5 Cabriolet represented a significant step forward in terms of technology, refinement, and driving dynamics compared to its predecessor. The “40 TDI” designation signifies a mid-range diesel engine offering, positioned below the more powerful 45 TDI and gasoline-powered variants. The inclusion of “quattro” denotes Audi’s renowned all-wheel-drive system, and “S tronic” identifies the seven-speed dual-clutch transmission. This combination aimed to deliver a balance of performance, efficiency, and all-weather capability.
Powertrain & Engine Architecture
At the heart of the A5 Cabriolet 40 TDI lies the 2.0-liter inline-four cylinder diesel engine, specifically the DESA or DETA engine code depending on minor specification variations. This engine is a turbocharged common-rail direct injection diesel, producing 190 horsepower at 3800-4200 rpm and a substantial 400 Nm (295 lb-ft) of torque between 1750 and 3000 rpm. The engine features a single turbocharger with an intercooler to enhance performance and efficiency. The fuel injection system utilizes piezo injectors for precise fuel delivery and optimized combustion. The S tronic seven-speed dual-clutch transmission provides rapid and smooth gear changes, contributing to both performance and fuel economy. This transmission is known for its efficiency and responsiveness, offering both automatic and manual shift modes. The engine is longitudinally mounted, directing power to all four wheels via Audi’s quattro all-wheel-drive system.
Driving Characteristics
The 40 TDI powertrain delivers a relaxed and refined driving experience. While not overtly sporty, the 190 hp and 400 Nm of torque provide ample power for comfortable cruising and confident overtaking. The S tronic transmission contributes to brisk acceleration, with a 0-60 mph time of around 7.6 seconds. The quattro all-wheel-drive system provides excellent traction in all weather conditions, enhancing stability and control. Compared to the higher-output 45 TDI, the 40 TDI offers slightly less outright performance, but its lower engine speed and optimized gearing contribute to improved fuel economy. Compared to manual transmission versions (which were less common in this configuration), the S tronic offers smoother shifts and reduced driver fatigue, particularly in urban traffic. The gear ratios are tuned for a balance of acceleration and fuel efficiency, with taller gearing in higher gears for relaxed highway cruising.
Equipment & Trim Levels
The A5 Cabriolet 40 TDI quattro S tronic typically came well-equipped as standard. Common 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 power-operated soft top. Safety features such as ABS, electronic stability control, and multiple airbags were standard. Optional extras included Audi’s Virtual Cockpit (a fully digital instrument cluster), a premium sound system, navigation, and various driver assistance systems like adaptive cruise control and lane departure warning. Trim levels varied by market, but generally offered options for upgraded interior materials, exterior styling enhancements, and additional comfort features.
Chassis & Braking
The A5 Cabriolet features a sophisticated chassis design with independent multi-link suspension at both the front and rear. This suspension setup provides a comfortable ride quality while maintaining good handling characteristics. The front suspension incorporates anti-roll bars to reduce body roll during cornering. Braking duties are handled by ventilated discs at the front and solid discs at the rear, providing ample stopping power. The ABS (Anti-lock Braking System) and electronic stability control systems further enhance safety and control. The chassis was tuned to accommodate the weight distribution of the diesel engine and all-wheel-drive system, ensuring balanced handling and predictable behavior.
Market Reception & Comparison
The A5 Cabriolet 40 TDI quattro S tronic was generally well-received by automotive critics. It was praised for its refined driving experience, comfortable ride, and efficient diesel engine. The combination of all-wheel drive and the dual-clutch transmission was also highlighted as a positive attribute. Compared to the gasoline-powered A5 Cabriolet variants, the 40 TDI offered significantly better fuel economy, making it a more practical choice for long-distance driving. Compared to the more powerful 45 TDI, the 40 TDI represented a more affordable entry point into the A5 Cabriolet range, appealing to buyers who prioritized efficiency and value over outright performance. Reliability reports have generally been positive, with the 2.0 TDI engine proving to be a durable and dependable unit.
Legacy
The Audi A5 Cabriolet (F5) 40 TDI quattro S tronic remains a desirable used car option. The 2.0 TDI engine is known for its longevity and relatively low maintenance costs. The S tronic transmission, while requiring occasional servicing, is generally reliable. The quattro all-wheel-drive system continues to provide excellent traction and stability. As a result, well-maintained examples of this variant command reasonable prices in the used car market. The F5 A5 Cabriolet, in general, is considered a well-engineered and stylish convertible, and the 40 TDI variant offers a compelling combination of performance, efficiency, and practicality.
