The Audi A5 Cabriolet 2.7 TDI V6 with the Multitronic transmission, produced between November 2008 and 2011, represents a compelling blend of open-air motoring and diesel efficiency within the 8F7 generation A5 lineup. Positioned as a mid-range offering, it slotted between the more economical 2.0 TDI models and the performance-oriented 3.0 TDI variants. This configuration aimed to provide a balance of respectable power, comfortable cruising, and relatively good fuel economy for a premium convertible. The A5 Cabriolet itself was Audi’s answer to the BMW 3 Series Convertible and Mercedes-Benz CLK (later E-Class) Cabriolet, offering a stylish and technologically advanced alternative in the luxury convertible segment.

Powertrain & Engine Architecture
At the heart of the A5 Cabriolet 2.7 TDI lies the CGKA engine code, a 2.7-liter V6 diesel engine. This engine is a member of the Volkswagen Group’s modular engine family, known for its robust construction and relatively smooth operation. The CGKA utilizes a common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A single turbocharger, coupled with an intercooler, provides forced induction, boosting power and torque. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, enhancing breathing and contributing to its power output. The Multitronic transmission is a continuously variable transmission (CVT) offering smooth, stepless gear changes. It utilizes a chain-driven system, providing a different driving experience compared to traditional automatic transmissions with fixed gear ratios.
Driving Characteristics
The 190 horsepower and 400 Nm (295 lb-ft) of torque delivered by the 2.7 TDI engine, combined with the Multitronic transmission, resulted in a comfortable and capable driving experience. Acceleration from 0-60 mph took approximately 8.2 seconds, and top speed was electronically limited to 137.94 mph. While not a sports car, the engine provided ample power for highway cruising and overtaking. The Multitronic transmission, while smooth, sometimes lacked the responsiveness of a traditional automatic or manual gearbox. Gear ratios were continuously adjusted to maintain optimal engine speed, prioritizing fuel efficiency over outright performance. Compared to the more powerful 3.0 TDI, the 2.7 TDI offered a more relaxed driving experience, and compared to the 2.0 TDI, it provided a noticeable increase in power and refinement.
Equipment & Trim Levels
The 2.7 TDI Cabriolet typically came well-equipped, reflecting Audi’s premium positioning. Standard features included leather upholstery, automatic climate control, a multi-function steering wheel, and an Audi Concert audio system. Optional extras included navigation, heated seats, parking sensors, and a premium Bang & Olufsen sound system. Trim levels varied by market, but generally offered options for upgraded interior materials, exterior styling enhancements, and additional driver-assistance features. The open-top experience was enhanced by a fully automatic fabric roof, which could be raised or lowered in a matter of seconds.
Chassis & Braking
The A5 Cabriolet featured a sophisticated chassis designed to provide a balance of comfort and handling. The front suspension utilized an independent multi-link setup, while the rear employed an independent multi-link spring suspension with a stabilizer bar. This configuration minimized body roll and provided a controlled ride. Braking duties were handled by ventilated discs at the front and solid discs at the rear, coupled with an Anti-lock Braking System (ABS). The steering was a rack-and-pinion system with electric power assistance, offering precise control and a comfortable driving experience.
Market Reception & Comparison
The Audi A5 Cabriolet 2.7 TDI was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and refined driving experience. The 2.7 TDI engine was considered a good compromise between performance and fuel economy. However, some critics noted that the Multitronic transmission could feel somewhat detached and lacked the engagement of a traditional gearbox. Compared to its rivals, the A5 Cabriolet offered a compelling package of luxury, technology, and practicality. Fuel economy was a strong point, with combined figures around 36.2 US mpg, making it an attractive option for drivers seeking a convertible without sacrificing efficiency.
Legacy
The 2.7 TDI engine, while generally reliable, is known to require regular maintenance, particularly regarding the turbocharger and fuel injection system. The Multitronic transmission, while smooth, can be prone to issues if not serviced properly. Today, well-maintained examples of the A5 Cabriolet 2.7 TDI can be found on the used car market at relatively affordable prices. They represent a stylish and comfortable open-top motoring experience, offering a blend of German engineering and diesel efficiency. The CGKA engine, when properly cared for, can provide many years of reliable service, making this variant a viable option for those seeking a premium convertible with reasonable running costs.
