Trunk dimensions Mercedes-Benz CLS Coupe

The trunk of the 2018 Mercedes-Benz CLS Coupe offers a volume of about 18.4 cu ft, which can be expanded to approximately 49.4 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, focusing on comfort and functionality.

The trunk dimensions vary slightly within the model range, but the shape remains consistently sporty and elegant. The loading edge is relatively low, making loading easier.

Practical details such as an electric tailgate and a well-thought-out storage system increase user-friendliness. Overall, the CLS Coupe combines appealing aesthetics with practical features that simplify everyday life.

Model Information

The Mercedes Benz CLS Coupe is an elegant four-door coupe that offers a combination of sporty design and luxurious comfort. The latest series of the CLS is characterized by a distinctive front end with a large grille and slim LED headlights.

The interior is equipped with high-quality materials and modern infotainment systems. The CLS is known for its dynamic driving characteristics and offers a range of powerful engines that ensure both efficiency and performance.

Variants of the Same Series

The CLS Coupe is part of the Mercedes-Benz E-Class, but there are other variants in this series such as the E-Class sedan, the E-Class convertible, and the E-Class wagon. These models differ in body style and functionality.

While the CLS Coupe focuses on sporty design, the sedan and wagon offer more space and practicality. It is important not to confuse these models as they target different customer groups.

Model Year Differences

The current model updates for the CLS Coupe were introduced in 2021, with design and technology updates. In previous years, especially 2018, there were significant changes in body shape and dimensions, which also affected trunk volume.

These adjustments aim to improve aerodynamics and make the interior more comfortable, including the trunk.

Direct Competitors

In the same price range and size category, models such as the BMW 6 Series Gran Coupe and the Audi A7 Sportback can be found. The BMW 6 Series offers a trunk volume of about 20.5 cu ft, while the Audi A7 provides around 18.9 cu ft.

Compared to the CLS Coupe, the BMW 6 Series has more cargo space, while the Audi A7 offers a similar capacity. These differences can be decisive for buyers who value trunk volume.

More Affordable Alternatives

For buyers looking for similar trunk dimensions but with a smaller budget, models like the Volkswagen Arteon or the Ford Mondeo could be considered.

The Volkswagen Arteon offers a trunk volume of about 19.9 cu ft, while the Ford Mondeo provides around 18.5 cu ft. These alternatives offer a good combination of space and value without sacrificing the comfort and features expected from a premium vehicle.

Trunk Volume

The Mercedes‑Benz CLS Coupe (2021) offers a trunk volume of 18.4 cu ft (manufacturer specification). This is about 23.8% more than an average car. Relative to the total vehicle volume, the trunk accounts for around 7.7%, which is 1.3 percentage points more than average.

Everyday impact: 18.4 cu ft reliably accommodate several suitcases, shopping trips, or a stroller plus carry-on luggage. For vacations and larger shopping trips, the capacity is above average.

Limitations may still occur with very bulky or tall items—especially since the coupe silhouette results in a flatter loading opening or lower interior height in the rear.

Vehicle Size and Parking Friendliness

Dimensions: 196.5 in length, 74.4 in width, 56.7 in height. Compared to an average car, the CLS is about 16.9 in longer (≈ +9.4%), 1.6 in wider (≈ +2.1%), and 5.1 in lower (≈ −8.2%).

Parking and maneuvering consequences: The vehicle is generally usable in standard parking spaces—according to data, it is 0.4 in shorter and 24 in narrower than a “normal parking spot.” Still, the greater length and width mean less room when maneuvering and in tight parking garages.

Garages with limited depth, narrow driveways, or tight parking spots require careful maneuvering.

Trunk Usability and Flexibility

Strengths: The volume of 18.4 cu ft makes the trunk suitable for everyday use and travel, especially for luggage, shopping, or child-related items. The comparatively high share of total volume indicates efficient space utilization.

Practical notes: Actual usability depends on the shape and height of the loading opening as well as the rear seat concept (e.g., pass-through or foldable seats).

In coupes, the rear shape is often flatter, which can make storing very tall or irregularly shaped items more difficult, even if the liter measurement looks large on paper.

General Model Information

Recognition: The CLS is positioned as a four-door coupe—a sportily styled sedan with a pronounced silhouette and premium aspirations.

Special features: Elegant design and coupe proportions with comparatively large trunk volume. Typical are good long-distance comfort features and high-quality interior options.

Characteristics: Coupe roofline can limit rear headroom and trunk opening; at the same time, the greater length/width provides more presence and space but makes parking in tight areas more difficult.

Price/performance ratio: Positioned in the premium segment—higher purchase and equipment costs, but design, comfort, and image. The strong trunk volume makes the CLS comparatively practical in its segment.

Competitor models: In the same class or competition are models like the Audi A7 Sportback, the BMW 8 Series/6 Series Gran Coupe, and partly the Porsche Panamera—also coupe-like sedans with premium claims.
