The Audi A6 Sedan (C8) 45 TFSI S tronic, launched in 2019, is part of the eighth generation (C8) of Audi’s A6 line. Built on the MLB Evo platform (shared with other Volkswagen Group vehicles like the Porsche Macan and Audi Q7), the C8 represented a significant leap forward in technology and design for the A6. The “45 TFSI” designation indicates the engine output, a convention Audi uses for model naming. This variant offered a compelling alternative to the more expensive and powerful 55 TFSI and the diesel-powered TDI models, targeting buyers who prioritized a balance of performance, fuel efficiency, and technological features. It quickly became a popular choice in both European and North American markets.

Powertrain & Engine Architecture

At the heart of the A6 45 TFSI lies the EA888 2.0-liter turbocharged four-cylinder engine. Specifically, engine codes DLBA, DKNA, and DLHA were used depending on the market and specific production year. This engine utilizes direct fuel injection (FSI) and an integrated exhaust manifold for improved turbocharger response. The turbocharger itself is a twin-scroll unit, further enhancing responsiveness and reducing turbo lag. The engine produces 245 horsepower at 5000-6500 rpm and 272.9 lb-ft of torque between 1600 and 4300 rpm. The engine is mated to Audi’s seven-speed S tronic dual-clutch transmission. This transmission offers incredibly fast and smooth gear changes, contributing to both performance and efficiency. Unlike a traditional automatic transmission with a torque converter, the S tronic uses two clutches – one for even gears and one for odd gears – allowing for pre-selection of the next gear. This results in virtually seamless shifts. The transmission is front-wheel drive in this configuration, although Audi’s quattro all-wheel drive system was available as an option on higher trim levels.

Driving Characteristics

The A6 45 TFSI S tronic delivers a refined and comfortable driving experience. While not as overtly sporty as the higher-output 55 TFSI model, it provides ample power for everyday driving and highway passing. The S tronic transmission contributes to brisk acceleration, with a 0-60 mph time of around 6.5 seconds. The engine’s broad torque curve ensures strong pull throughout the rev range. The front-wheel-drive configuration offers good traction in most conditions, but can exhibit some torque steer under hard acceleration. Compared to the manual transmission versions (available in some markets), the S tronic offers greater convenience and ease of use, particularly in urban traffic. The gear ratios are tuned for a balance of acceleration and fuel economy, with a relatively tall seventh gear for efficient cruising.

Equipment & Trim Levels

The A6 45 TFSI S tronic typically came well-equipped as standard. Features included Audi’s Virtual Cockpit digital instrument cluster, a 10.1-inch touchscreen infotainment system with MMI Navigation plus, leather upholstery, three-zone automatic climate control, and a suite of driver-assistance systems such as Audi pre sense basic and lane departure warning. Optional extras included a Bang & Olufsen sound system, adaptive cruise control, a head-up display, and matrix LED headlights. Trim levels varied by market, but generally offered increasing levels of luxury and technology. Higher trims often included upgraded interior materials, larger wheels, and additional driver-assistance features.

Chassis & Braking

The C8 A6 features a sophisticated chassis design. Both front and rear suspensions utilize a multi-link setup, providing a comfortable ride and precise handling. The suspension is tuned to prioritize comfort, but still offers good body control. The A6 45 TFSI typically came equipped with ventilated front disc brakes and solid rear discs. ABS (Anti-lock Braking System) is standard, along with electronic stability control. The steering is electric power-assisted, providing a light and precise feel.

Market Reception & Comparison

The A6 45 TFSI S tronic was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, comfortable ride, and high-tech interior. Compared to the 55 TFSI, the 45 TFSI offered a more affordable entry point into the A6 range, while still providing a satisfying driving experience. The 45 TFSI also offered better fuel economy than the more powerful engine. Against competitors like the BMW 530i and Mercedes-Benz E300, the A6 45 TFSI was considered a strong contender, offering a compelling combination of performance, luxury, and technology.

Legacy

The EA888 2.0-liter turbocharged engine and S tronic transmission have proven to be remarkably reliable powertrains. While some early C8 A6 models experienced minor software glitches, these were generally addressed through software updates. The engine is known for its durability and relatively low maintenance costs. On the used car market, the A6 45 TFSI S tronic remains a popular choice, offering a good value proposition for buyers seeking a well-equipped and refined executive sedan. Its blend of performance, efficiency, and technology ensures its continued appeal for years to come.
