Powertrain & Engine Architecture
The heart of the A5 Cabriolet 45 TFSI is the DMTA engine, a 2.0-liter inline-four cylinder gasoline engine. This powerplant utilizes direct fuel injection and a single turbocharger with an intercooler to deliver a balance of performance and efficiency. The engine benefits from Audi’s Virtual Valve Lift (VVL) technology, which allows for variable valve lift on the intake side, optimizing engine performance across a wider range of engine speeds. The mild hybrid system incorporates a 12V belt alternator-starter (BAS) and a small lithium-ion battery. This system allows for extended start-stop operation, regenerative braking, and a slight power boost during acceleration. The seven-speed S tronic dual-clutch transmission provides rapid and smooth gear changes, contributing to the car’s overall responsiveness. The quattro all-wheel-drive system distributes power between the front and rear axles as needed, enhancing traction and stability, particularly in adverse weather conditions.
Driving Characteristics
The 265 horsepower and 272.9 lb.-ft. of torque delivered by the 45 TFSI engine provide brisk acceleration. The 0-60 mph sprint is achieved in approximately 5.7 seconds, making it a genuinely quick convertible. The S tronic transmission’s quick shifts and the quattro system’s surefootedness contribute to a confident driving experience. Compared to lower-powered A5 Cabriolet variants, such as the 40 TFSI, the 45 TFSI offers a noticeable performance upgrade. While not as overtly sporty as the S5 Cabriolet, the 45 TFSI strikes a good balance between performance and everyday usability. The gear ratios are tuned for a blend of acceleration and fuel economy, with the transmission generally selecting the appropriate gear for the driving situation. The mild hybrid system is largely imperceptible during normal driving, but it contributes to improved fuel efficiency, especially in city traffic.
Equipment & Trim Levels
The A5 Cabriolet 45 TFSI typically came well-equipped as standard. Features included leather upholstery, three-zone automatic climate control, Audi’s MMI infotainment system with a 10.1-inch touchscreen display, and a suite of driver-assistance systems such as lane departure warning and automatic emergency braking. Optional extras included a Bang & Olufsen sound system, virtual cockpit (a fully digital instrument cluster), adaptive cruise control, and various interior trim upgrades. The specific trim level (Premium, Premium Plus, or Prestige) determined the standard equipment and available options. The Prestige trim, for example, often included features like navigation, a head-up display, and parking assistance.
Chassis & Braking
The A5 Cabriolet utilizes an independent multi-link suspension system at both the front and rear axles. This setup provides a comfortable ride quality while maintaining good handling characteristics. The suspension is tuned to balance comfort and control, making it suitable for both long-distance cruising and spirited driving. The steering is precise and well-weighted, providing good feedback to the driver. Braking duties are handled by ventilated discs at all four corners. The braking system is responsive and provides ample stopping power. Anti-lock brakes (ABS) and electronic stability control (ESC) are standard features, enhancing safety and stability.
Market Reception & Comparison
The Audi A5 Cabriolet 45 TFSI was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and engaging driving experience. The mild hybrid system was seen as a positive step towards improved fuel efficiency. Compared to rivals such as the BMW 4 Series Convertible and Mercedes-Benz C-Class Cabriolet, the A5 Cabriolet offered a compelling combination of features, performance, and value. Fuel economy figures of 7.8-8.7 l/100 km (30.2-27 US mpg) were competitive within its segment. Reliability reports generally indicated good reliability, although some owners reported minor issues with the infotainment system.
Legacy
The A5 Cabriolet 45 TFSI represents a refined and technologically advanced open-top experience. The 2.0-liter turbocharged engine and S tronic transmission have proven to be durable and reliable powertrains. On the used car market, these models hold their value reasonably well, particularly those with low mileage and a comprehensive service history. The integration of mild hybrid technology demonstrates Audi’s commitment to improving fuel efficiency and reducing emissions. As a modern classic, the A5 Cabriolet 45 TFSI continues to appeal to buyers seeking a stylish, comfortable, and capable convertible.
