Introduction
The A5 Cabriolet, launched in 2009 as a replacement for the A4 Cabriolet, quickly established itself as a stylish and sophisticated alternative to traditional hardtop convertibles. The F5 generation, introduced in 2017, brought a more refined design and advanced technology. The 2019 facelift further enhanced the A5 Cabriolet with updated styling, improved efficiency, and the introduction of mild hybrid technology across several engine options. The 40 TFSI Mild Hybrid S tronic variant, beginning production in 2020, aimed to deliver a compelling combination of performance and economy, appealing to a broad range of buyers in the premium convertible segment.
Powertrain & Engine Architecture
At the heart of the A5 Cabriolet 40 TFSI lies the DMSA engine, a 1.984-liter inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and a single turbocharger with an intercooler to deliver 204 horsepower and 320 Nm (236 lb-ft) of torque. The engine’s architecture incorporates Audi’s Valvelift system, which adjusts valve lift on the intake side to optimize performance and efficiency. The mild hybrid system, a 48-volt electrical system, features a belt starter generator (BSG) that recovers energy during deceleration and assists the engine during acceleration, improving fuel economy and reducing emissions. The seven-speed S tronic dual-clutch transmission provides quick and smooth gear changes, contributing to a responsive driving experience. This transmission is known for its efficiency and ability to deliver power seamlessly.
Driving Characteristics
The 40 TFSI S tronic combination in the A5 Cabriolet delivers a balanced driving experience. While not as overtly sporty as the higher-output variants, the 204 hp engine provides ample power for comfortable cruising and spirited driving. Acceleration from 0 to 60 mph takes approximately 7.1 seconds, and the car reaches a top speed of 147 mph. The S tronic transmission’s quick shifts and well-chosen gear ratios contribute to a feeling of responsiveness. Compared to the manual transmission options, the S tronic offers greater convenience and ease of use, particularly in urban environments. The mild hybrid system provides a subtle boost during acceleration, enhancing the overall driving feel. The weight distribution, typical of front-engine, front-wheel-drive vehicles, contributes to predictable handling, though it lacks the agility of rear-wheel-drive or quattro all-wheel-drive models.
Equipment & Trim Levels
The 40 TFSI Mild Hybrid S tronic trim typically included a generous level of standard equipment. This included Audi’s MMI Navigation Plus infotainment system with a 10.1-inch touchscreen display, Audi Virtual Cockpit (a fully digital instrument cluster), three-zone automatic climate control, and leather upholstery. Standard safety features included Audi pre sense basic, lane departure warning, and a rearview camera. Optional extras included features like adaptive cruise control, a Bang & Olufsen sound system, and various interior trim upgrades. The A5 Cabriolet offered a range of customization options, allowing buyers to tailor the car to their individual preferences.
Chassis & Braking
The A5 Cabriolet’s chassis is designed to provide a comfortable yet engaging driving experience. The front suspension utilizes independent multi-link suspension, while the rear features an independent multi-link spring suspension with a stabilizer bar. This setup provides a good balance between ride comfort and handling precision. The braking system consists of ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, enhancing safety and control. The steering is an electric power steering system, providing precise and responsive steering feel.
Market Reception & Comparison
The A5 Cabriolet 40 TFSI Mild Hybrid S tronic was generally well-received by automotive critics. Reviewers praised its refined driving experience, comfortable ride, and stylish design. The mild hybrid system was noted for its contribution to improved fuel economy without significantly impacting performance. Compared to the more powerful 45 TFSI variant, the 40 TFSI offered a more affordable entry point into the A5 Cabriolet range, while still providing a satisfying driving experience. Fuel economy figures of 6.5-7.4 l/100km (36.2-31.8 US mpg) were competitive within its class. Reliability reports suggest that the DMSA engine and S tronic transmission are generally reliable, although regular maintenance is crucial.
Legacy
The Audi A5 Cabriolet 40 TFSI Mild Hybrid S tronic represents a key step in Audi’s transition towards greater electrification. The integration of mild hybrid technology demonstrated Audi’s commitment to improving fuel efficiency and reducing emissions. On the used car market, these models are generally sought after for their blend of style, comfort, and technology. The DMSA engine, while not the most powerful in the A5 lineup, has proven to be a durable and reliable unit when properly maintained. As a result, the 40 TFSI variant continues to be a popular choice for buyers seeking a premium open-top experience.
