Powertrain & Engine Architecture
The heart of the A4 Cabriolet 3.2 FSI quattro Tiptronic is the AUK or BKH engine code, a 3.2-liter naturally aspirated V6 engine. This engine utilizes Audi’s FSI (Fuel Stratified Injection) direct injection technology, which allows for precise fuel delivery and improved combustion efficiency. The engine boasts a high compression ratio of 12.5:1 and a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder. This configuration contributes to its responsive nature and high-revving capability. The engine produces 255 horsepower at 6500 rpm and 330 Nm (243 lb-ft) of torque at 3250 rpm. Paired with this engine is a six-speed Tiptronic automatic transmission, offering both fully automatic operation and the ability for the driver to manually select gears for more engaging driving. The Tiptronic transmission is designed to provide smooth and quick shifts, complementing the engine’s power delivery.
Driving Characteristics
The 3.2 FSI V6 with the Tiptronic transmission delivers a noticeably more spirited driving experience compared to the lower-powered A4 Cabriolet variants. Acceleration from 0 to 60 mph takes approximately 7 seconds, and the car feels confident at highway speeds. The Tiptronic transmission, while not as sporty as a manual gearbox, offers a good balance between convenience and control. The quattro all-wheel drive system provides excellent traction in all weather conditions, enhancing stability and confidence. The gear ratios are tuned for a blend of acceleration and fuel efficiency, but the emphasis is clearly on performance. Compared to the 1.8T models, the 3.2 FSI offers significantly more torque throughout the rev range, resulting in effortless overtaking and a more engaging driving experience.
Equipment & Trim Levels
The 3.2 FSI quattro Tiptronic typically came well-equipped as the top-of-the-line A4 Cabriolet. Standard features included leather upholstery, automatic climate control, a premium sound system, and power-adjustable front seats. Optional extras included features like navigation system, heated seats, and upgraded interior trim packages. The exterior often featured unique styling cues, such as larger alloy wheels and chrome accents, to differentiate it from the lower trims. The interior dashboard configuration was consistent with other B7 A4 models, but the 3.2 FSI often received additional aluminum trim accents.
Chassis & Braking
The A4 Cabriolet’s chassis features an independent multi-link suspension at both the front and rear, providing a comfortable ride and precise handling. The suspension is tuned to balance comfort and control, offering a good compromise for both city driving and spirited backroad excursions. Braking duties are handled by ventilated discs at the front and solid discs at the rear, equipped with ABS (Anti-lock Braking System) for enhanced safety. The braking system is generally considered adequate for the car’s performance, providing confident stopping power.
Market Reception & Comparison
The Audi A4 Cabriolet 3.2 FSI quattro Tiptronic was generally well-received by automotive critics. It was praised for its powerful engine, refined driving experience, and luxurious interior. However, some critics noted that the Tiptronic transmission could feel slightly less responsive than a manual gearbox. Fuel economy was also a point of concern, as the 3.2-liter V6 engine is not particularly fuel-efficient. Compared to the 1.8T and 2.0T models, the 3.2 FSI offered a significant performance upgrade but came at a higher price point and with increased running costs.
Legacy
The 3.2 FSI V6 engine, while not without its quirks, has proven to be a relatively reliable powertrain when properly maintained. The timing chain is a known potential failure point, and regular oil changes are crucial for longevity. Today, the A4 Cabriolet 3.2 FSI quattro Tiptronic represents a desirable option for enthusiasts seeking a stylish and capable open-top luxury car. Values have remained relatively stable, and well-maintained examples are sought after by collectors and drivers alike. The combination of a powerful engine, all-wheel drive, and a comfortable interior makes it a compelling choice in the used car market.
