2019 Audi A6 Sedan (C8) Dimensions, Size & Specs

The width of the Audi A6 Sedan C8 ranges from 1866 mm to 1886 mm (73.5 to 74.3 inches) without the mirrors. When the side mirrors are extended, the total width increases to 2110 mm (83.1 inches). This expanded width with mirrors is important to consider for tight garage or parking spaces to ensure adequate clearance.

The height of the Audi A6 Sedan C8 varies very slightly between 1457 mm and 1459 mm (approximately 57.4 to 57.4 inches). This moderate height contributes to a sleek aerodynamic profile, but still offers ample headroom for front and rear passengers, enhancing comfort especially on longer journeys.

The curb weight of the Audi A6 Sedan C8 varies between 1640 kg and 2010 kg (3615 to 4430 lbs). This broad range depends on the specific engine version, drivetrain configuration (front-wheel or Quattro all-wheel drive), selected options, and trim. Generally, weight influences handling characteristics and fuel efficiency.

The maximum vehicle weight for the Audi A6 Sedan C8 ranges from 2230 kg up to 2610 kg (4915 to 5750 lbs). This includes passengers, cargo, and the vehicle itself. Understanding this limit is crucial for safe loading and towing capacities, as overloading can affect braking, handling, and longevity of vehicle components.

This generation of Audi A6 Sedan offers a luggage capacity ranging from 360 liters to 530 liters (approximately 12.7 to 18.7 cubic feet) with rear seats upright. When the rear seats are folded down, the cargo space expands substantially, reaching up to 995 liters (about 35.1 cubic feet). This flexible cargo space accommodates everyday needs and larger loads comfortably.

The Audi A6 Sedan C8, with its width including mirrors at 2110 mm (83.1 inches), length up to 4951 mm (194.9 inches), and height around 1457 mm (57.4 inches), generally fits within a standard residential garage which typically measures about 2400-2700 mm wide and 4800-6000 mm deep. However, due to its mirror width, care should be taken while opening doors and maneuvering inside to avoid contact with garage walls or objects.

Compared to the previous C7 generation A6, the C8 model is slightly longer and lower. The length increased from about 4930 mm (194.1 inches) in the C7 to up to 4951 mm (194.9 inches) in the C8, while height dropped marginally from around 1460 mm to 1457 mm. The width also expanded, especially with mirrors included, enhancing road presence and interior space. These dimensional changes contribute to a more modern and aerodynamic profile with improved interior comfort.

The Audi A6 Sedan C8 is very competitive in size within the executive sedan class. It is slightly longer than the BMW 5 Series G30, which measures roughly 4936 mm (194.3 inches), and close to the Mercedes-Benz E-Class W213 at approximately 4923 mm (193.8 inches). Width with mirrors is comparable across all three models, but the A6’s subtle aerodynamic height gives it a slightly sleeker roofline. This makes the A6 among the roomiest and most refined vehicles in its segment.

The Audi A6 Sedan C8 offers a broad selection of rim sizes from 17 inches (7.5J x 17) up to 21 inches (8.5J x 21) with corresponding tire sizes such as 225/60 R17, 245/45 R19, 255/40 R20, and 255/35 R21. Larger wheels and lower profile tires typically enhance handling and steering response but may trade-off ride comfort. This variety lets buyers tailor the balance between sporty performance and comfort based on preference.
