The Audi A3 Sportback 3.2 V6 quattro S tronic, produced from 2008 to 2009, represented the performance pinnacle of the 8PA facelifted A3 Sportback range. Positioned as the flagship model, it offered a substantial power upgrade and all-wheel drive capability compared to the more common 1.6, 1.8, and 2.0-liter variants. This model was primarily aimed at the European market, where compact premium hatchbacks with powerful engines and sophisticated drivetrains were highly sought after. It slotted above the 2.0 TFSI quattro in terms of performance and price, offering a naturally aspirated V6 experience in a relatively small package.

Powertrain & Engine Architecture
The heart of the A3 3.2 V6 quattro was the BUB engine code, a 3.2-liter naturally aspirated V6. This engine featured a 60-degree V-angle, contributing to its relatively compact size. It utilized multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The engine produced 250 horsepower at 6,300 rpm and 320 Nm (236 lb-ft) of torque between 2,500 and 3,000 rpm. The engine’s design prioritized smooth power delivery over outright peak power, making it a flexible and responsive unit. Paired with the engine was the 6-speed S tronic dual-clutch transmission, which provided quick and seamless gear changes. The S tronic, unlike a traditional automatic, offered both fully automatic operation and the ability to manually shift gears via steering wheel-mounted paddles or the gear selector.
Driving Characteristics
The 3.2 V6 quattro S tronic offered a distinctly different driving experience compared to the lower-powered A3 variants. The combination of the naturally aspirated V6 and the quick-shifting S tronic resulted in brisk acceleration – 0 to 62 mph in 6.3 seconds. The quattro all-wheel drive system provided excellent traction, particularly in adverse weather conditions. While not as fuel-efficient as the turbocharged engines, the 3.2 V6 offered a more linear and predictable power delivery. The S tronic transmission’s gear ratios were tuned for a balance of acceleration and cruising efficiency. Compared to the 2.0 TFSI, the 3.2 V6 felt less peaky and offered more readily available torque throughout the rev range.
Equipment & Trim Levels
The 3.2 V6 quattro S tronic typically came well-equipped, reflecting its position as the range-topping model. Standard features included climate control, a multi-function steering wheel, alloy wheels (typically 17-inch), and a high-quality audio system. Interior upholstery was usually a combination of cloth and leather, with options for full leather trim. Optional extras included a sunroof, navigation system, parking sensors, and upgraded sound systems. The interior trim generally featured aluminum or wood accents, adding to the premium feel.
Chassis & Braking
The A3 Sportback 3.2 V6 quattro featured a fully independent suspension system, with MacPherson struts at the front and a multi-link setup at the rear. The suspension was tuned to provide a comfortable ride while maintaining good handling characteristics. Braking duties were handled by ventilated discs at the front and solid discs at the rear, with ABS (Anti-lock Braking System) as standard. The quattro all-wheel drive system distributed power between the front and rear axles as needed, enhancing stability and grip.
Market Reception & Comparison
The A3 3.2 V6 quattro S tronic was generally well-received by automotive critics. It was praised for its smooth engine, quick transmission, and all-weather capability. However, its higher price and relatively poor fuel economy compared to the 2.0 TFSI models were noted. The 2.0 TFSI offered similar performance with better fuel efficiency, making it a more popular choice for many buyers. The 3.2 V6 appealed to those who prioritized a refined driving experience and the prestige of a V6 engine.
Legacy
The BUB engine, while not known for any widespread reliability issues, requires regular maintenance, including oil changes and timing belt replacements. The S tronic transmission is generally reliable but can be expensive to repair if problems arise. Today, the A3 3.2 V6 quattro S tronic represents a relatively rare and desirable variant. Well-maintained examples hold their value reasonably well, appealing to enthusiasts who appreciate its unique combination of performance, refinement, and all-wheel drive capability. It remains a testament to Audi’s commitment to offering a wide range of options within its model lineup, catering to diverse customer preferences.
