Powertrain & Engine Architecture
At the heart of the A4 3.2 FSI lies the EA390 engine, a naturally aspirated 3.2-liter V6. This engine, designated CALA, utilizes direct fuel injection (FSI – Fuel Stratified Injection) to enhance efficiency and power output. The FSI system injects fuel directly into the combustion chamber, allowing for precise control of the air-fuel mixture and higher compression ratios. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its responsive nature. The 3.2L V6 produces 265 horsepower at 6,500 rpm and 243 lb-ft of torque between 3,000 and 5,000 rpm. Paired with this engine is Audi’s Multitronic continuously variable transmission (CVT). Unlike traditional automatic transmissions with fixed gear ratios, the Multitronic uses a chain-driven system to provide a virtually infinite number of ratios, optimizing engine efficiency and providing smooth acceleration.
Driving Characteristics
The 3.2 FSI with Multitronic offers a distinctly different driving experience compared to the four-cylinder A4 variants. The V6 provides ample power for effortless cruising and confident overtaking. While not as overtly sporty as the S4, the 3.2 delivers a refined and engaging driving experience. The Multitronic transmission contributes to smooth, seamless acceleration, although some drivers may find it lacks the direct feel of a traditional automatic or dual-clutch transmission. The transmission’s programming prioritizes fuel efficiency, meaning it doesn’t always hold lower gears for maximum performance. The 0-60 mph time of around 6.2 seconds is respectable for its era, placing it firmly in the performance sedan category.
Equipment & Trim Levels
The 3.2 FSI typically came well-equipped, often including features like leather upholstery, tri-zone automatic climate control, a premium sound system, and parking sensors. Optional extras included navigation, sunroof, and advanced driver-assistance systems. Trim levels varied by market, but generally, the 3.2 FSI represented a step up from the base Premium trim, often aligning with the Prestige package in the US market. Interior appointments were characterized by Audi’s renowned build quality and attention to detail, with high-quality materials and a driver-focused layout.
Chassis & Braking
The A4 B8 featured a sophisticated chassis design with independent multi-link suspension at all four corners. This setup provided a comfortable ride while maintaining good handling characteristics. The 3.2 FSI models typically featured slightly stiffer suspension tuning compared to the base models to better manage the increased power. Braking duties were handled by ventilated discs at the front and solid discs at the rear, providing adequate stopping power for everyday driving. Anti-lock braking system (ABS) was standard, enhancing safety and control.
Market Reception & Comparison
The A4 3.2 FSI was generally well-received by automotive critics, who praised its refined engine, comfortable ride, and high-quality interior. However, some reviewers noted that the Multitronic transmission could feel less engaging than other options. Compared to the 2.0T models, the 3.2 FSI offered a significant performance advantage but came at a higher price point and with slightly lower fuel economy. Against competitors like the BMW 335i and Mercedes-Benz C350, the A4 3.2 FSI offered a compelling blend of luxury, performance, and technology.
Legacy
The EA390 3.2 FSI V6 engine, while not without its quirks, proved to be a relatively reliable powerplant when properly maintained. The Multitronic transmission, however, has a reputation for requiring more frequent and specialized servicing. Regular fluid changes are crucial to prevent premature failure. Today, the A4 3.2 FSI represents a good value on the used car market, offering a refined and capable driving experience at an affordable price. However, prospective buyers should be aware of the potential maintenance costs associated with the Multitronic transmission and ensure a thorough pre-purchase inspection is conducted.
