Powertrain & Engine Architecture
The heart of this A4 Cabriolet is the BPP engine, a 2.7-liter V6 turbodiesel. This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The engine boasts four valves per cylinder and a double overhead camshaft (DOHC) configuration, contributing to its efficient breathing and power output. A turbocharger with an intercooler further enhances performance by forcing more air into the cylinders. The engine produces 180 horsepower between 3300 and 4250 rpm and a substantial 380 Nm (280 lb-ft) of torque from 1400 to 3300 rpm. This broad torque curve is a hallmark of diesel engines, providing strong pulling power across a wide range of engine speeds. The engine is paired with Audi’s Multitronic continuously variable transmission (CVT). This transmission offers smooth, stepless gear changes, enhancing driving comfort and optimizing fuel efficiency. Unlike traditional automatic transmissions with fixed gear ratios, the Multitronic allows the engine to operate at its most efficient point at all times.
Driving Characteristics
The 2.7 TDI with the Multitronic transmission delivers a refined and relaxed driving experience. While not overtly sporty, the engine’s ample torque provides brisk acceleration, with a 0-60 mph time of around 8.6 seconds. The Multitronic transmission contributes to seamless acceleration, avoiding the noticeable shifts of a conventional automatic. The CVT’s programming prioritizes fuel efficiency, resulting in a slightly less responsive feel compared to the manual transmission options. However, drivers can utilize a manual shift mode for more control. The front-wheel-drive configuration provides predictable handling, although it lacks the all-weather capability of Audi’s quattro all-wheel-drive system. The Cabriolet’s chassis is well-tuned, offering a comfortable ride without excessive body roll.
Equipment & Trim Levels
The 2.7 TDI Multitronic typically came equipped with a generous level of standard features. These included automatic climate control, power windows and mirrors, a multi-function steering wheel, and an upgraded audio system. Interior upholstery was typically a cloth or leather combination. Optional extras included full leather upholstery, heated front seats, a sunroof, and a navigation system. The specific trim level (e.g., SE, Sport) determined the availability of certain features and cosmetic enhancements.
Chassis & Braking
The A4 Cabriolet B7 utilizes an independent multi-link suspension system at both the front and rear axles. This sophisticated suspension design provides a good balance between ride comfort and handling precision. The front suspension features ventilated disc brakes, while the rear brakes are typically solid discs. Anti-lock Braking System (ABS) is standard, enhancing braking performance and stability. Stabilizer bars are fitted to both axles to reduce body roll during cornering.
Market Reception & Comparison
The 2.7 TDI Multitronic A4 Cabriolet was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined powertrain. However, some reviewers noted that the Multitronic transmission could feel somewhat detached compared to a traditional manual gearbox. Compared to the 1.8L petrol versions, the 2.7 TDI offered significantly more torque and better fuel economy. It was a more practical choice for long-distance driving. Compared to the 3.0 TDI, it offered a more affordable entry point into the A4 Cabriolet range, albeit with slightly less power.
Legacy
The BPP 2.7 TDI engine, when properly maintained, is known for its durability and longevity. The Multitronic transmission, however, can be a potential weak point, requiring regular fluid changes and careful driving habits to avoid premature failure. Today, the A4 Cabriolet 2.7 TDI represents a relatively affordable entry into the world of Audi convertibles. Well-maintained examples are sought after by enthusiasts who appreciate their blend of style, comfort, and fuel efficiency. Finding a car with a fully documented service history, particularly regarding the Multitronic transmission, is crucial when considering a purchase.
