2018-2020 Audi A6 Avant (C8) 45 TFSI (245 Hp) quattro S tronic

Technical Specifications

The Audi A6 Avant (C8) 45 TFSI quattro S tronic, launched in 2018, is a station wagon based on the C8 platform, also underpinning the A6 sedan. This generation marked a significant leap forward in technology and design for the A6, incorporating a new MMI touch response system, mild-hybrid technology, and a more sophisticated chassis. The “45 TFSI” designation indicates the engine’s power output relative to Audi’s internal naming convention, translating to a 2.0-liter turbocharged four-cylinder engine producing 245 horsepower. The “quattro” label signifies Audi’s renowned all-wheel-drive system, and “S tronic” denotes the seven-speed dual-clutch transmission. This particular variant aimed to provide a balance between performance, fuel efficiency, and practicality for buyers seeking a premium wagon experience.

Powertrain & Engine Architecture

At the heart of the A6 Avant 45 TFSI lies the EA888 2.0-liter turbocharged inline-four engine, specifically coded DLBA, DKNA, or DLHA depending on the specific production date and market. This engine utilizes a direct injection system, delivering fuel directly into the combustion chambers for improved efficiency and power. The turbocharger, coupled with an intercooler, provides forced induction, boosting power output. The engine features variable valve timing on both the intake and exhaust sides, optimizing performance across the rev range. The seven-speed S tronic dual-clutch transmission offers rapid and smooth gear changes, contributing to both performance and fuel economy. This transmission is known for its efficiency and responsiveness, providing a more engaging driving experience than a traditional torque-converter automatic. The quattro all-wheel-drive system employs a self-locking center differential, distributing torque between the front and rear axles as needed to maximize traction.

Driving Characteristics

The A6 Avant 45 TFSI quattro S tronic delivers a refined and capable driving experience. While not as overtly sporty as the higher-performance S6, the 245 hp engine provides ample power for everyday driving and confident overtaking. The S tronic transmission contributes to brisk acceleration, with 0-60 mph times around 5.9 seconds. The quattro all-wheel-drive system provides excellent grip in all weather conditions, enhancing stability and confidence. The suspension is tuned for comfort, absorbing bumps and imperfections in the road with ease. Compared to the 2.0-liter TDI diesel variants, the 45 TFSI offers a more responsive and engaging driving experience, albeit with slightly higher fuel consumption. The gear ratios are optimized for both acceleration and highway cruising, providing a comfortable and efficient ride.

This configuration provides a comfortable ride while maintaining precise handling. The steering is electrically assisted, offering a balanced feel and responsive control. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The ABS (Anti-lock Braking System) and electronic stability control systems enhance safety and stability. The weight distribution is well-balanced, contributing to the car’s neutral handling characteristics.
