Powertrain & Engine Architecture
At the heart of the A6L 45 TFSI lies the DLBA engine, a 2.0-liter inline-four cylinder gasoline engine. This powerplant utilizes direct fuel injection and is coupled with a single twin-scroll turbocharger and intercooler. This configuration allows for a broad torque curve and responsive power delivery. The engine produces 224 horsepower at 5000-6000 rpm and 370 Nm (272.9 lb-ft) of torque between 1600 and 4500 rpm. The S tronic seven-speed dual-clutch transmission provides rapid and smooth gear changes, contributing to both performance and efficiency. The ‘ultra’ designation in ‘quattro ultra’ indicates a demand-driven all-wheel-drive system. Under normal driving conditions, the system operates primarily in front-wheel drive, engaging the rear axle only when traction demands it, optimizing fuel economy.
Driving Characteristics
The A6L 45 TFSI offers a comfortable and composed driving experience. The 224 hp output, while not overtly sporty, provides ample power for everyday driving and highway overtaking. The S tronic transmission contributes to brisk acceleration, with a 0-60 mph time of approximately 7.1 seconds. Compared to higher-output variants like the 50 TFSI, the 45 TFSI prioritizes fuel efficiency and a smoother, less aggressive driving style. The quattro ultra system provides excellent stability and grip in various weather conditions, though it may not offer the same level of dynamic engagement as a full-time quattro system. The gear ratios are tuned for a balance between acceleration and fuel economy, with taller gearing in higher gears for relaxed cruising.
Equipment & Trim Levels
The A6L 45 TFSI typically comes well-equipped with standard features including leather upholstery, a panoramic sunroof, a premium sound system, and a comprehensive suite of driver-assistance systems. The interior features Audi’s MMI touch response system, a dual-screen infotainment system controlling various vehicle functions. Optional extras often include upgraded leather packages, adaptive cruise control, a head-up display, and matrix LED headlights. Trim levels within the 45 TFSI variant may vary depending on the specific market, but generally offer increasing levels of luxury and technology.
Chassis & Braking
The A6L 45 TFSI utilizes an independent multi-link suspension setup for both the front and rear axles, providing a comfortable ride and precise handling. The suspension is tuned to balance comfort and control, absorbing bumps effectively while maintaining stability in corners. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The electric power steering offers a light and precise feel, enhancing maneuverability. Stabilizer bars are fitted to both axles to reduce body roll during cornering.
Market Reception & Comparison
The A6L 45 TFSI was generally well-received by automotive critics, praised for its comfortable ride, refined interior, and advanced technology. Compared to other trims in the A6L lineup, the 45 TFSI offered a more accessible price point while still delivering a luxurious experience. Fuel economy figures of around 31.4 US mpg combined were competitive within its segment. Reliability reports have been generally positive, with the 2.0-liter engine proving to be a durable and dependable unit. However, some owners have reported minor issues with the infotainment system.
Legacy
The Audi A6L 45 TFSI quattro ultra S tronic represents a key model in Audi’s strategy to offer a compelling blend of performance, efficiency, and luxury in the executive sedan segment. The 2.0-liter turbocharged engine and S tronic transmission have proven to be a reliable and popular combination, and the quattro ultra all-wheel-drive system provides added confidence in challenging driving conditions. In the used car market, these models continue to hold their value, appealing to buyers seeking a well-equipped and technologically advanced sedan with a proven track record.
