The Audi A5 Cabriolet, specifically the 45 TFSI quattro ultra S tronic variant produced from 2019 to 2020, represents a mid-cycle refresh (facelift) of the F5 generation A5 Cabriolet. Positioned as a premium open-top offering, this model combined a potent turbocharged four-cylinder engine with Audi’s quattro all-wheel-drive system and a quick-shifting seven-speed S tronic dual-clutch transmission. It aimed to deliver a balance of performance, luxury, and everyday usability within the A5 Cabriolet range, slotting in as a step up from the base 40 TFSI models and below the more powerful S5 Cabriolet.

Powertrain & Engine Architecture
At the heart of the A5 45 TFSI Cabriolet lies the EA888 2.0-liter turbocharged four-cylinder engine, specifically the DKNA engine code. This engine is a direct-injection powerplant featuring an aluminum block and cylinder head. The turbocharger, coupled with an intercooler, provides significant boost, contributing to the engine’s 245 horsepower output at 5000-6500 rpm and 272.9 lb-ft of torque available from a low 1600 rpm to 4300 rpm. The engine utilizes a variable valve timing system on both the intake and exhaust sides to optimize performance and efficiency across the rev range. The S tronic seven-speed dual-clutch transmission delivers rapid and smooth gear changes, enhancing the driving experience. Audi’s ‘quattro ultra’ all-wheel-drive system is employed, which intelligently switches between front-wheel drive and all-wheel drive as needed to improve fuel economy.
Driving Characteristics
The 45 TFSI S tronic combination provides a noticeably more engaging driving experience than the base 40 TFSI models. The increased power and torque deliver brisk acceleration, with a 0-60 mph time of around 6.2 seconds. The S tronic transmission contributes to this, offering quick shifts and a responsive feel. While not as overtly sporty as the S5 Cabriolet, the 45 TFSI provides ample power for comfortable highway cruising and spirited driving on winding roads. The quattro all-wheel-drive system provides excellent traction and stability in various weather conditions. The gear ratios are tuned for a balance between acceleration and fuel efficiency, with taller gearing in higher gears for relaxed cruising.
Equipment & Trim Levels
The A5 45 TFSI Cabriolet typically came well-equipped as standard. Features included leather upholstery, three-zone automatic climate control, Audi’s MMI infotainment system with a 7-inch display, and a suite of driver-assistance systems such as Audi pre sense basic. Optional extras included a larger 10.1-inch MMI touch response display, a Bang & Olufsen sound system, navigation, virtual cockpit, and various interior trim options. Exterior options included different wheel designs, paint colors, and the addition of carbon fiber trim elements. The specific trim level (Premium, Premium Plus, etc.) dictated the standard equipment and available options.
Chassis & Braking
The A5 Cabriolet utilizes a sophisticated suspension setup designed to balance comfort and handling. The front suspension features independent multi-link design, while the rear also employs a multi-link setup. This configuration provides excellent wheel control and a comfortable ride. The 45 TFSI model typically came equipped with ventilated front disc brakes and solid rear discs. ABS (Anti-lock Braking System) is standard, along with electronic stability control. The steering is a speed-sensitive electric power steering system, providing precise and responsive steering feel.
Market Reception & Comparison
The A5 45 TFSI Cabriolet was generally well-received by automotive critics. It was praised for its refined driving experience, comfortable interior, and stylish design. Compared to the base 40 TFSI model, the 45 TFSI offered a significant performance upgrade without the higher price tag of the S5. Fuel economy was considered reasonable for a performance-oriented convertible, averaging around 35.6 mpg combined. Reliability reports suggest that the EA888 engine is generally robust, although preventative maintenance, such as regular oil changes, is crucial.
Legacy
The 2.0-liter turbocharged engine found in the A5 45 TFSI Cabriolet has become a mainstay in the Audi lineup and is known for its reliability and tunability. The S tronic transmission has also proven to be a durable and efficient unit. On the used car market, these models hold their value reasonably well, particularly those with low mileage and a well-maintained service history. The combination of performance, luxury, and all-weather capability makes the A5 45 TFSI Cabriolet a desirable option for buyers seeking a premium open-top experience.
