Trunk dimensions Mercedes-Benz S-Class

The trunk of the Mercedes-Benz S-Class sedan 2018 offers a volume of about 18 cu ft, which can be expanded up to 35.3 cu ft by folding down the rear seats. The rear bench is split 60:40, allowing flexibility when transporting larger items.

The interior is designed with high quality, featuring a flat loading floor and a low loading lip that makes loading and unloading easier.

The trunk dimensions vary slightly depending on the model variant but generally remain spacious and practical. Typical features include the elegant shape and thoughtful layout that combine both functionality and style.

Model Information

The latest series of the Mercedes-Benz S-Class sedan represents the pinnacle of luxury automobiles. This model range combines advanced technology with elegant design and offers a variety of amenities for drivers and passengers.

The S-Class is known for its superior driving dynamics, comfort, and safety features, making it one of the most sought-after sedans on the market.

Variants of the Same Series

The Mercedes-Benz S-Class is available in several variants, including the sedan, coupe, and convertible. It is important not to confuse these models as they have different body styles and characteristics.

While the sedan is designed for maximum comfort and space, the coupe and convertible offer sportier driving performance and an open driving experience.

Model Year Differences

The Mercedes-Benz S-Class has undergone several model changes over the years that have affected the body dimensions and trunk measurements.

In particular, the generations introduced in 2014 and 2020 brought significant changes in size and design. These changes led to an optimization of the trunk and improved the overall functionality of the vehicle.

Direct Competitors

In the same price range and size, the S-Class sedan competes with models like the BMW 7 Series and the Audi A8. The trunk of the BMW 7 Series offers a volume of about 18.2 cu ft, while the Audi A8 is slightly smaller with around 17.8 cu ft.

These differences in trunk volume can be decisive for buyers who value cargo space.

More Affordable Alternatives

For buyers looking for similar trunk dimensions as the S-Class but with a smaller budget, there are some alternatives. Models like the Volkswagen Arteon offer a trunk volume of about 19.9 cu ft and are generally more affordable.

The Skoda Superb is also an option with a trunk volume of up to 22.1 cu ft, making it a practical choice for buyers who value cargo space.

Trunk Volume

The trunk volume of the Mercedes-Benz S-Class sedan 2021 is reported differently: approx. 15.9 cu ft as an average, 12.4 cu ft (manufacturer specification), and 19.4 cu ft (independent measurements).

Compared to the average, the volume is thus 7.14% larger. Relative to the total vehicle volume, the trunk accounts for about 5.9%, which is −0.6 percentage points less than the average.

Vehicle Size and Parking Friendliness

The dimensions are: 203.9 in length, 76.8 in width, 59.1 in height. Compared to an average car, the S-Class is 24.4 in longer (+13.6%), 3.9 in wider (+5.6%), and 2.4 in lower (−3.9%). It is also 7.1 in longer than a standard parking space but 21.7 in narrower.

Practical implications: The greater length makes parking in tight city spots more difficult and can cause space issues in short garages.

The slightly greater width increases the space needed in parking rows, but the vehicle is narrower than many parking spaces, so door opening in standard bays usually remains possible. The low height facilitates underground garage access but hardly affects presence and ease of entry/exit.

Trunk Usability and Flexibility

The significant variation in volume figures indicates different measurement methods and interpretations of usable space (e.g., measurement up to loading height, inclusion of cavities or underfloor compartments). For practical purposes, this means:

With a realistic volume around 15.9 cu ft, the trunk is well suited for shopping trips, everyday use, and weekend travel.
The height and shape of the cargo area determine the ability to transport bulky items — here, pure liter figures are less meaningful; a test loading is recommended.
Since the trunk is proportionally somewhat smaller than average, the S-Class invests volume in favor of passenger space and technology/comfort inside the cabin.

General Model Information

The Mercedes-Benz S-Class is the brand’s flagship and stands for high comfort, extensive assistance and comfort technology, as well as first-class interior materials.

Typical characteristics include extensive customization options, widely varying equipment levels, and often longer wheelbases (compared to sedans in lower classes).

Price/performance ratio: The S-Class belongs to the upper price segment — buyers receive top comfort but less trunk space per vehicle volume than some competitors or more practical sedans.

Main competitors are models like the BMW 7 Series and the Audi A8 (or similar luxury sedans). Compared to them, the S-Class is more focused on comfort and technological top equipment than on maximum cargo volume.
