2019 Audi A6L Sedan (C8) Dimensions, Size & Specs

The curb weight of the Audi A6 Long (C8) sedan ranges from approximately 1800 kg to 1980 kg (around 3968 to 4366 lbs). This variation depends on trim levels, options such as wheel size (18, 19, or 20 inches), drivetrain configurations, and additional features. The weight balance contributes to the car's stable ride quality and performance dynamics.

The Audi A6 Long (C8) sedan has a ride height or ground clearance of 117 mm (4.6 inches). This relatively low ground clearance enhances aerodynamics and stability at higher speeds, typical of executive sedans, but may require caution on uneven roads or speed bumps to avoid scraping the underbody.

With the rear seats folded down, the Audi A6 Long (C8) provides a luggage capacity of 430 liters (15.2 cubic feet). This generous volume accommodates larger cargo and makes the model practical for activities like weekend getaways, grocery shopping, or transporting moderate amounts of luggage, balancing passenger comfort and utility.

The Audi A6 Long (C8) supports rims in sizes 18, 19, and 20 inches, with corresponding tire sizes of 225/55 R18 102Y XL, 245/45 R19 102Y XL, and 255/40 R20 101Y XL respectively. Larger rims and lower profile tires offer sharper handling and more aggressive styling but may slightly reduce ride comfort compared to smaller wheel setups preferred for smoother cruising.

The Audi A6 Long (C8) measures 1886 mm (74.3 inches) in width excluding mirrors, and 2110 mm (83.1 inches) with mirrors open. Most standard home garages have widths around 2400 mm (94.5 inches), so the car fits comfortably inside with some clearance for opening doors. However, care is advised when opening mirrors or maneuvering in tight spaces to avoid collisions.

Compared to its predecessor, the Audi A6 Long (C7), the C8 generation is noticeably larger and more refined. The C8 lengthens to 5038 mm from the previous C7's approximate 4930 mm (194.1 inches), offering increased rear legroom and cabin space. Width and height have also subtly increased, enhancing interior comfort and presence, while incorporating modern styling and tech upgrades making it a more spacious and advanced executive sedan.

The Audi A6 Long (C8) competes in the executive sedan segment with models like the BMW 5 Series and Mercedes-Benz E-Class. With a length of 5038 mm, it tends to be slightly longer than many rivals, translating to superior rear passenger space, especially in long-wheelbase versions. Width and height dimensions are comparable, but the Audi’s thoughtful interior packaging and modern design provide a competitive balance of spaciousness, luxury, and driving dynamics.

For drivers prioritizing comfort on the Audi A6 Long (C8), 18-inch rims paired with 225/55 R18 tires offer a good cushion against road irregularities and maintain a smooth ride. Alternatively, those seeking sportier handling may select 19- or 20-inch rims with lower profile tires (245/45 R19 or 255/40 R20), which improve cornering precision and responsiveness but may result in a firmer ride due to thinner tire sidewalls.

While the Audi A6 Long (C8) is among the larger executive sedans due to its extended length of over 5 meters, it remains fairly agile thanks to modern steering and driver assistance technologies. Though its size requires mindful maneuvering in tight urban spaces and parking lots, features like parking sensors, cameras, and optional automated parking help mitigate these challenges, enabling confident handling in city driving conditions.
