Trunk dimensions Audi A8

The trunk of the Audi A8 sedan 2018 offers a volume of about 17.8 cu ft, which can be expanded up to 42.4 cu ft by folding down the rear seats. The rear bench is split in a 40:20:40 ratio, allowing flexibility when transporting larger items.

The interior is designed with high quality, featuring a practical loading edge that facilitates loading and unloading.

The trunk dimensions vary slightly within the model range but generally remain spacious and functional. Typical features include the elegant shape and thoughtful interior design, combining both style and practicality.

Model Information

The Audi A8 is the luxury sedan from the German automaker Audi, representing top engineering and innovative technologies. The latest series of the A8 combines elegant design with state-of-the-art equipment, offering both driving comfort and sporty performance.

With various engine options, including V6 and V8 variants as well as a hybrid drive, the A8 is tailored to the needs of discerning drivers. The interior is equipped with high-quality materials and the latest infotainment technology, making the A8 one of the leading models in the luxury sedan segment.

Variants of the Same Series

The Audi A8 is mainly offered as a sedan. However, there are variants such as the Audi A0.3 cu ft, which is an extended version providing more rear passenger space.

These models should not be confused as they have different dimensions and equipment features. The A0.3 cu ft targets buyers who place special emphasis on comfort and space.

Yearly Differences

Model changes to the Audi A8 affecting body and trunk dimensions mainly occurred in 2010, 2014, and 2022. The generation introduced in 2010 brought a new platform and improved dimensions, while the 2014 and 2022 updates mainly included technical improvements and design adjustments.

These changes generally also impact trunk design and usability.

Direct Competition

In the luxury sedan segment, the Audi A8 competes with models like the Mercedes-Benz S-Class and the BMW 7 Series. The Mercedes-Benz S-Class offers a trunk volume of about 18 cu ft, while the BMW 7 Series provides slightly more space at around 18.2 cu ft.

These differences are minor but can be decisive for buyers who rely on cargo space. Competitor models also offer similar transport options, but interior layouts and user experience vary.

More Affordable Alternatives

For buyers seeking similar trunk dimensions as the Audi A8 but with a smaller budget, models like the Skoda Superb or Volkswagen Passat offer interesting alternatives.

The Skoda Superb has a trunk volume of up to 22.1 cu ft, making it one of the most spacious vehicles in its class. The Volkswagen Passat also offers an appealing trunk volume of about 20.7 cu ft. These models combine good space with an attractive price-performance ratio.

Trunk Volume

The figures for the trunk of the Audi A8 sedan 2022 vary: manufacturer specification 13.8 cu ft, independent measurements up to 17.8 cu ft, an average of about 15.8 cu ft was cited from the data package; other sources mention around 15.5 cu ft.

Statistically overall, the volume is slightly above average (+≈6.6%), while the share of vehicle volume is slightly below average (-0.5 percentage points).

In practice, this means: The A8 offers a solid luggage volume for an upper-class sedan — sufficient for luggage of two to three travelers or everyday shopping. Whether the trunk volume is closer to ~13.8 cu ft or near 17.7 cu ft in a specific case depends on measurement method and usability.

Vehicle Size and Parking Friendliness

Dimensions: 204.3 in length, 76.8 in width, 57.9 in height. Compared to an average car, the A8 is significantly longer (+24.8 in) and somewhat wider (+3.9 in), but lower (-3.5 in).

Everyday implications:

Parking: Due to its length, tight parking spaces or underground garage sections are more challenging; according to data, the A8 is 7.5 in longer than a standard parking space, requiring more longitudinal space when parking. In width, there is usually enough room as it is ≈22 in narrower than a standard parking spot.
Garages and passages: The low height is advantageous for low underground garages; the length and weight require more caution during turning maneuvers and maneuvering.
Visibility: Large rear headrests and the absence of a rear wiper can impair rear visibility; all-around visibility values indicate partly restricted views due to pillars and headrests.

Trunk Usability and Flexibility

Important practical features:

Rear seatbacks cannot be folded down (not even optionally). There is only a pass-through for narrow, long items. The storage volume is therefore not expandable.
The trunk lid is electrically standard; hands-free opening by foot gesture is factory available — this facilitates loading.
The loading edge is at 27.6 in above the road, with an internal step of 6.3 in — making lifting heavy items less practical than with flatter loading surfaces.
The trunk opening in sedans is typically narrower than in wagons or SUVs; combined with non-retractable headrests, this further limits loading bulky items.

Practical conclusion: The A8 is well suited for suitcases, shopping bags, or several beverage crates (reports mention up to seven crates).

For longer or very bulky transports, it is unsuitable due to the lack of foldable rear seats and narrow opening — here wagons, SUVs, or large sedans with pass-through/folding functions are superior.

General Model Information

Familiarity and positioning: The Audi A8 2022 is Audi’s flagship sedan in the premium segment. It is regarded as technically sophisticated, comfort-oriented, and luxuriously equipped.

Special features and peculiarities:

High-quality comfort features such as electric doors with automatic closing, optional OLED lighting system, and hands-free trunk opening.
Unusual operating details: doors unlock electrically with a slight pull on the handle and can be mechanically opened by a strong pull in case of power failure.
Visibility and operation compromises: bulky, non-retractable rear headrests and no rear wiper on the sedan can affect everyday visibility and comfort.

Price-performance ratio: As an upper-class sedan, the A8 targets buyers who prioritize comfort, technology, and brand positioning over maximum cargo flexibility. Compared to SUVs or wagons, the loading offer is less variable, but materials, ride comfort, and assistance systems are excellent.

Competitors: Main rivals are Mercedes-Benz S-Class, BMW 7 Series, and Lexus LS. Those seeking more loading flexibility tend to look at large wagons or luxury SUVs.
