Audi A6 Sedan
Audi’s highest Cd value of 0.23
Although it is a four-door sedan, which is at a disadvantage in terms of aerodynamics, the entire body is designed with a strong aerodynamic focus, achieving the best aerodynamic level in Audi’s history with a Cd value of 0.23.
In March 2025, Audi added the A6 Avant, equipped with a TFSI gasoline turbo and a TDI diesel turbo, to the A6 series, which was launched as a fully electric vehicle. Following the Avant station wagon, the long-awaited four-door notchback saloon, the A6 Sedan, has now made its debut.
The new A6 Sedan boasts exceptional aerodynamics, with a Cd value of 0.23, the highest in Audi history, and a conservative four-door style that suits business situations. In addition to the introduction of 48V mild hybrid technology “MHEV plus,” it is equipped with adaptive air suspension and all-wheel steering, achieving the high level of comfort and sharp handling required in this class.
The clear and functional exterior is a typical Audi design, with no unnecessary elements. The company claims that a high level of aerodynamics has been ensured by the curved lines above the windows, the side air intakes with optimized form and function, and the front spoiler that controls the airflow under the body. The front section, with its sharp, thin headlights and large single frame with four rings in the center, exudes a powerful presence.
The taillights, featuring a vertical triple graphic, also emphasize the car’s distinctive rear section. The notchback shape, which continues into the traditional six-light window side sections, and the sharply curved trunk lid contribute greatly to the car’s excellent aerodynamics. Combined with the wide, large diffuser, the amount of drag around the rear axle is also kept low.
Three types of ICE powertrains available
Like the previously introduced Avant, the lineup includes two gasoline and one diesel variants. The 2.0 turbo diesel and 3.0 turbo gasoline variants are equipped with the “MHEV plus” system.
Audi’s 48V mild hybrid system, the “MHEV plus” system, is available on both the 2.0-liter inline four-cylinder TDI diesel turbo with a maximum output of 150kW (204PS) and the 3.0-liter V6 TFSI gasoline turbo with a maximum output of 270kW (367PS). MHEV plus adds up to 230Nm of torque and 18kW (24PS) of power when starting and overtaking. Up to 25kW can be recovered during deceleration.
An entry-level model is also available, without the MHEV plus system, and with a 2.0-liter inline four-cylinder TFSI gasoline turbo that delivers a maximum output of 150kW (204 PS).
The A6 Sedan also receives comfortable upgrades to its interior acoustics. Improved window sealing and optimized door seals have resulted in up to 30 percent quieter cabins compared to the previous model. The tailgate seal also significantly reduces wind noise. All wheels 19 inches and larger are equipped with noise absorbers. Furthermore, newly developed engine and transmission mounting bushes contribute to a smoother, quieter ride.
