2019-2020 Audi A6 Sedan (C8) 50 TFSI e (299 Hp) Plug-in Hybrid quattro ultra S tronic

The Audi A6 50 TFSI e, produced from December 2019 to December 2020, represents Audi’s entry into the plug-in hybrid (PHEV) market within the C8 generation A6 sedan lineup. Positioned as a technologically advanced and fuel-efficient option, it combined a 2.0-liter turbocharged four-cylinder gasoline engine with an electric motor and a lithium-ion battery pack. This variant aimed to offer a balance between performance, reduced emissions, and the convenience of electric-only driving for shorter commutes. It was a key component of Audi’s strategy to offer electrified alternatives across its model range, appealing to environmentally conscious buyers and those seeking to benefit from potential tax incentives and lower running costs.

Technical Specifications

Powertrain & Engine Architecture

The A6 50 TFSI e’s powertrain centers around Audi’s DLGA 2.0-liter turbocharged inline-four cylinder gasoline engine. This engine, part of the EA888 family, produces 252 horsepower and 272.9 lb-ft of torque. It utilizes direct fuel injection and a single turbocharger with an intercooler to enhance efficiency and power output. The engine’s design incorporates features like variable valve timing on both intake and exhaust sides (DOHC) to optimize performance across the rev range. Coupled with this is a permanent magnet synchronous electric motor, integrated between the engine and the seven-speed S tronic dual-clutch transmission. This electric motor contributes an additional 143 horsepower and 258.15 lb-ft of torque. The combined system output reaches 299 horsepower and 331.9 lb-ft of torque. The 14.1 kWh (11.3 kWh usable) lithium-ion battery pack is located under the trunk floor, impacting cargo space slightly. The S tronic transmission is crucial, providing quick and smooth gear changes, and efficiently distributing power to all four wheels via Audi’s quattro all-wheel-drive system.

Driving Characteristics

The 50 TFSI e delivers a noticeably different driving experience compared to A6 models equipped with solely gasoline engines. In electric-only mode, the car offers near-silent acceleration and a range of approximately 28.58 to 36.04 miles (WLTP). The instant torque from the electric motor provides brisk acceleration from a standstill. When the gasoline engine engages, the transition is generally seamless. The combined power output results in a 0-60 mph time of around 5.9 seconds, making it a relatively quick sedan. The S tronic transmission’s quick shifts contribute to this performance. However, the added weight of the battery pack (approximately 443 lbs) is noticeable, particularly in handling compared to lighter A6 variants. The quattro all-wheel-drive system provides excellent traction in various conditions. The gear ratios are tuned to prioritize efficiency in hybrid mode, sometimes resulting in the engine holding a lower gear longer than in a traditional automatic transmission.

Equipment & Trim Levels

The 50 TFSI e typically came well-equipped, reflecting its position as a premium PHEV offering. Standard features generally included Audi’s virtual cockpit digital instrument cluster, a large infotainment touchscreen with navigation, leather upholstery, three-zone automatic climate control, and a suite of driver-assistance systems such as adaptive cruise control, lane departure warning, and automatic emergency braking. Optional extras included features like a Bang & Olufsen sound system, massaging front seats, and a head-up display. Trim levels were often aligned with the broader A6 range, with options like Premium, Premium Plus, and Prestige offering progressively more luxury and technology features. Exterior styling cues were generally similar to other A6 models, with subtle badging indicating the plug-in hybrid powertrain.

Chassis & Braking

The A6 50 TFSI e utilizes a sophisticated chassis design. It features an independent multi-link suspension at both the front and rear axles, optimized for comfort and handling. Transverse stabilizers are included to reduce body roll during cornering. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard, along with electronic brake-force distribution and brake assist. Due to the increased weight from the battery pack, the suspension components were often slightly stiffer compared to standard A6 models to maintain handling composure. The steering is an electric power-assisted rack and pinion system, offering precise and responsive control.

Market Reception & Comparison

The Audi A6 50 TFSI e was generally well-received by automotive critics. It was praised for its refined driving experience, efficient powertrain, and luxurious interior. However, some reviewers noted the reduced trunk space due to the battery pack and the slightly higher price compared to conventional A6 models. Compared to the A6 45 TFSI (2.0-liter gasoline engine), the 50 TFSI e offered significantly better fuel economy and the ability to drive in electric-only mode, but at the cost of some performance and practicality. Against other PHEV competitors like the BMW 530e and Mercedes-Benz E350e, the A6 50 TFSI e was often considered a strong contender, offering a compelling blend of luxury, technology, and efficiency.

Legacy

The A6 50 TFSI e represents an important step in Audi’s electrification strategy. While production was relatively short-lived, the powertrain proved to be generally reliable. The 2.0-liter turbo engine is well-established and known for its durability. The hybrid system components, including the battery pack and electric motor, have demonstrated reasonable longevity in real-world use. On the used car market, these models hold their value relatively well, appealing to buyers seeking a premium PHEV with a proven track record. Maintenance costs can be slightly higher than conventional A6 models due to the added complexity of the hybrid system, but the potential for fuel savings and reduced emissions continues to make it an attractive option.
