Powertrain & Engine Architecture
At the heart of the A6 2.8 FSI quattro S tronic lies the CHVA or CNYA engine code, a 2.8-liter naturally aspirated V6 engine. This engine utilizes direct fuel injection (FSI – Fuel Stratified Injection) to deliver fuel directly into the combustion chamber, enhancing efficiency and power output. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for improved performance. The 2.8L V6 produces 204 horsepower at 5250-6500 rpm and 280 Nm (206.52 lb-ft) of torque between 3000-5000 rpm. Paired with this engine is the 7-speed S tronic dual-clutch transmission, offering quick and smooth gear changes. The S tronic transmission contributes to both performance and fuel efficiency, providing a more responsive driving experience compared to a traditional torque converter automatic.
Driving Characteristics
The 2.8 FSI V6 with the S tronic transmission delivers a balanced driving experience. Acceleration from 0-60 mph takes approximately 7.7 seconds, and the car reaches a top speed of 149.13 mph. While not as overtly sporty as the higher-output versions, the 2.8L provides ample power for everyday driving and confident highway passing. The S tronic transmission’s quick shifts contribute to a feeling of responsiveness. Compared to the 2.0 TFSI models, the 2.8 FSI offers a noticeable increase in power and refinement. However, it doesn’t quite match the outright performance of the 3.0 TFSI supercharged V6. The quattro all-wheel drive system provides excellent traction in various weather conditions, enhancing stability and control.
Equipment & Trim Levels
The A6 2.8 FSI quattro S tronic typically came well-equipped, reflecting Audi’s commitment to luxury. Standard features often included leather upholstery, tri-zone automatic climate control, a multi-function steering wheel, and an Audi Concert audio system. Optional extras included features like navigation, a premium sound system (Bang & Olufsen), adaptive cruise control, and parking assistance systems. Interior trim options varied, with choices in wood or aluminum accents. The dashboard layout was characterized by Audi’s clean and modern design aesthetic.
Chassis & Braking
The C7 A6 features an independent multi-link suspension at the front and an independent suspension on trapezoidal levers at the rear, providing a comfortable and controlled ride. The 2.8 FSI models typically came equipped with ventilated front discs and solid rear discs. The quattro all-wheel drive system distributes power between the front and rear axles as needed, optimizing traction. ABS (Anti-lock Braking System) was standard, enhancing braking performance and safety. The steering system is a rack and pinion setup with electric power steering.
Market Reception & Comparison
The Audi A6 2.8 FSI quattro S tronic was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, comfortable ride, and luxurious interior. Fuel economy was considered reasonable for a V6-powered all-wheel drive sedan, achieving around 29.4 US mpg in combined driving. Compared to the 2.0 TFSI models, the 2.8 FSI offered a significant performance upgrade, while remaining more affordable than the 3.0 TFSI. Reliability was generally good, although some owners reported minor issues with electronic components.
Legacy
The 2.8 FSI V6 engine, while not the most common variant in the C7 A6 lineup, has proven to be a relatively reliable powertrain. The S tronic transmission, when properly maintained, is also known for its durability. In the used car market, these models offer a good balance of luxury, performance, and value. Regular maintenance, including timely oil changes and transmission servicing, is crucial for ensuring long-term reliability. The C7 A6 2.8 FSI quattro S tronic remains a desirable option for buyers seeking a refined and capable mid-size luxury sedan.
