2024 Audi A6 Sedan (C8, facelift 2023) Dimensions, Size & Specs

The curb weight of the 2024 Audi A6 Sedan (C8 facelift) varies between 1640 kg (3616 lbs) and 2010 kg (4430 lbs), depending on the specific configuration, engine, and optional equipment. This weight range reflects the balance Audi strikes between strong structural rigidity and use of lightweight materials, contributing to both safety and driving dynamics. Heavier models tend to include more advanced powertrains or additional luxury features, which may affect acceleration, fuel efficiency, and handling but also enhance ride comfort and stability at high speeds.

With mirrors opened, the Audi A6 Sedan (C8 facelift) is 2110 mm (83.1 inches) wide. This extended width due to side mirrors could impact the vehicle's ability to fit through tight parking spaces, narrow parking garage aisles, or congested urban streets. Drivers should be particularly cautious when maneuvering in areas with limited space to avoid contact with other vehicles or objects. The fairly wide stance also contributes positively to on-road stability and cornering performance.

The luggage capacity of the 2024 Audi A6 Sedan (C8 facelift) ranges from 360 liters (12.7 cubic feet) with rear seats upright to a maximum of 995 liters (35.1 cubic feet) when the rear seats are folded down. This flexibility allows the A6 to adapt to both daily commuting needs and larger cargo requirements such as transporting sports equipment, luggage for road trips, or other bulky items. The generous fold-down space enhances the vehicle’s practicality within the executive sedan class.

A typical single-car garage has an internal width of about 2.4 to 2.7 meters (94.5 to 106.3 inches) and a length around 5.0 to 6.0 meters (196.9 to 236.2 inches). Given the A6's length of 4939 mm (194.4 inches) and width of 1886 mm (74.3 inches) without mirrors, it will fit comfortably lengthwise and widthwise inside a standard garage. However, the opened mirror width of 2110 mm (83.1 inches) requires mindful mirror folding when maneuvering to ensure the mirrors do not scrape or hit the garage walls or other items.

Compared to the pre-facelift C8 Audi A6, the 2024 facelifted model maintains very similar overall dimensions and weight characteristics, reflecting Audi’s incremental design philosophy with this mid-cycle update. Both generations share a length close to 4.94 meters (194.5 inches) and comparable widths around 1.88 meters (74 inches). Weight differences are minimal but can exist depending on updated technology and equipment packages introduced with the facelift. This means while some styling and tech enhancements were made, the core physical size and driving dynamics remain closely aligned with its predecessor.

When compared to competitors such as the BMW 5 Series, Mercedes-Benz E-Class, and Volvo S90, the 2024 Audi A6 Sedan (C8 facelift) is dimensionally very competitive. Its length of 4939 mm (194.4 inches) puts it in the same size class, with a width of 1886 mm (74.3 inches), which is slightly narrower than some rivals but with comparable interior space. Technically, the facelift introduced improved infotainment and mild-hybrid technology, keeping pace with the segment's trend toward electrification and digitalization. Overall, the A6 balances luxury, technology, and dimensions to remain one of the top choices in the executive sedan segment.

The slight variation in height—from 1457 mm to 1459 mm (57.4 to 57.5 inches)—in the 2024 Audi A6 Sedan (C8 facelift) is typically due to different suspension setups, wheel sizes, or optional equipment such as roof rails or slight ride height adjustments. Though minor, these variations could influence aerodynamics slightly but mostly impact the vehicle’s stance and ride comfort. A marginally higher height with larger wheel sizes or adaptive suspension will offer better road absorption and a softer ride, while a sportier, lower variant might emphasize sharper handling at a minimal cost to comfort.

The 2024 Audi A6 Sedan (C8 facelift) is equipped with a broad range of rim sizes from 17 inches through 21 inches (rims sized 7.5J x 17 up to 21 inches), paired with tire sizes including 225/60 R17, 225/55 R18, 245/45 R19, 255/40 R20, and 255/35 R21. Larger rims with lower-profile tires generally provide sharper handling responses and improved cornering grip but can reduce ride comfort on rough roads due to less sidewall cushioning. Smaller rims with higher-profile tires deliver a smoother ride and better absorption of road imperfections but may produce slightly less precise steering feedback. Audi offers this range so buyers can customize their balance between comfort and sportiness.

The 2024 Audi A6 Sedan (C8 facelift) has a maximum roof load capacity of 90 kg (198 lbs). This limit accommodates roof-mounted accessories such as cargo boxes, roof racks, bicycles, or skis, within reason and safety guidelines. It’s important to stay within this weight limit to avoid adversely affecting the car’s handling, stability, and structural integrity. When loading the roof, users should ensure the weight is evenly distributed, secure the load firmly, and consider the added height and aerodynamic effects on fuel economy and wind noise.
