The Audi A5 Coupe (8T3) 2.7 TDI V6 with the Multitronic transmission represents a compelling blend of performance and efficiency within the second-generation A5 lineup, produced from July 2007 to 2011. Positioned as a mid-range offering, it slotted between the entry-level 1.8 TFSI and the more potent 3.0 TDI variants. This model aimed to provide a refined driving experience with strong torque delivery, appealing to buyers seeking a comfortable grand tourer with respectable fuel economy. The 8T3 chassis, shared with the A4, offered a sophisticated platform for Audi’s design and engineering prowess.

Technical Specifications

INTRODUCTION

The Audi A5 Coupe (8T3) 2.7 TDI V6 Multitronic, launched in 2007, was a key component of Audi’s strategy to offer a diverse range of A5 models. Built on the Volkswagen Group’s 8K platform (also known as the B8 platform for the A4), the A5 Coupe aimed to deliver a more stylish and sporty alternative to the A4 sedan. The 2.7 TDI variant, equipped with the Multitronic continuously variable transmission (CVT), was designed to appeal to drivers prioritizing fuel efficiency and smooth power delivery over outright performance. It occupied a middle ground in the A5 lineup, offering a step up in refinement and power compared to the 1.8 TFSI, while remaining more accessible than the range-topping 3.0 TDI.

Powertrain & Engine Architecture

At the heart of the A5 2.7 TDI lies the CAMA or CGKA engine code, a 2.7-liter V6 diesel engine. This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The engine features a single turbocharger with an intercooler to increase air density and boost power output. The valvetrain employs double overhead camshafts (DOHC) with four valves per cylinder, contributing to efficient gas exchange. The Multitronic transmission, a six-speed CVT, is a defining feature of this variant. Unlike traditional automatic transmissions with fixed gear ratios, the Multitronic uses a chain-driven system to provide a virtually infinite number of gear ratios, resulting in seamless acceleration and optimized fuel efficiency. The Multitronic is known for its smooth operation and ability to keep the engine within its optimal power band.

Driving Characteristics

The 2.7 TDI with the Multitronic transmission delivers a distinctly different driving experience compared to the manual transmission or higher-output A5 variants. While not as overtly sporty as the 3.0 TDI, the 2.7 TDI offers ample torque – 400 Nm (295 lb-ft) – available from a low 1400 rpm. This provides strong acceleration in everyday driving situations, making overtaking and merging onto highways effortless. The Multitronic transmission contributes to a smooth and refined driving experience, eliminating the shift shock often associated with traditional automatics. However, some drivers may find the transmission less engaging than a manual gearbox. The CVT’s tendency to hold the engine at a constant rpm during acceleration can also result in a somewhat droning engine note. The 0-60 mph time of around 7.2 seconds is respectable, but noticeably slower than the more powerful A5 models.

Equipment & Trim Levels

The A5 2.7 TDI Multitronic typically came well-equipped, reflecting Audi’s reputation for interior quality and technology. Standard features often included leather upholstery, automatic climate control, a multi-function steering wheel, and an Audi Concert audio system. Optional extras were plentiful, including navigation systems, premium sound systems (Bose or Bang & Olufsen), parking sensors, and bi-xenon headlights. Trim levels varied depending on the market, but generally offered progressive upgrades in terms of interior materials, exterior styling, and technology features. Sport packages were available, adding features like sport seats, lowered suspension, and larger alloy wheels.

Chassis & Braking

The A5 Coupe’s chassis features an independent multi-link suspension at both the front and rear, providing a comfortable ride and precise handling. The 2.7 TDI variant typically utilized slightly softer spring rates compared to the higher-performance models to prioritize ride comfort. Braking duties are handled by ventilated discs at the front and solid discs at the rear, equipped with ABS (Anti-lock Braking System). The steering is a rack-and-pinion system with electric power assistance, offering a responsive and precise feel.

Market Reception & Comparison

The Audi A5 2.7 TDI Multitronic was generally well-received by automotive critics. It was praised for its refined driving experience, strong fuel economy, and comfortable interior. However, some reviewers noted that the Multitronic transmission lacked the engagement of a manual gearbox, and the engine, while capable, wasn’t as exhilarating as the 3.0 TDI. Compared to the 1.8 TFSI, the 2.7 TDI offered significantly more torque and a more relaxed driving experience, making it better suited for long-distance journeys. The 3.0 TDI, while more expensive, provided substantially more power and performance. Fuel economy was a strong point for the 2.7 TDI, consistently achieving around 36.8 US mpg in combined driving.

Legacy

The 2.7 TDI engine, while generally reliable, is known to require diligent maintenance, particularly regarding the diesel particulate filter (DPF) and turbocharger. The Multitronic transmission, while smooth, can be prone to issues if not serviced regularly. Proper fluid changes are crucial for its longevity. Today, the A5 2.7 TDI can be found on the used car market at relatively affordable prices. It remains a stylish and comfortable coupe, offering a good balance of performance, efficiency, and refinement. However, potential buyers should be aware of the potential maintenance costs associated with the diesel engine and Multitronic transmission, and ensure a thorough inspection is conducted before purchase.
