What Exactly is CLA Boot Space Measurement?

Your Mercedes-Benz CLA’s boot space measurement, often referred to as cargo volume or trunk capacity, is a standardized way of quantifying how much room is available for storage. This measurement is crucial for car buyers comparing vehicles and for owners planning trips or purchases that require transporting goods. It tells you how much you can practically fit into the trunk without compromising the vehicle’s aesthetics or safety.
Manufacturers typically express this capacity in liters (L) or cubic feet (cu ft). This standardized unit allows for easy comparison between different car models, even those from competing brands. The figure provided represents the volume of the cargo area up to the underside of the parcel shelf or rear window, whichever is lower. It’s designed to be a consistent metric, though real-world usability can sometimes feel different depending on the shape of the space and any obstructions within it.
Why Understanding Boot Space Matters
For a vehicle like the Mercedes-Benz CLA, which balances sporty aesthetics with a degree of everyday practicality, boot space is a significant consideration. Whether you’re a young professional needing to transport work essentials, a couple heading for a weekend escape, or a family managing weekly shopping, the trunk’s capacity can be a deal-breaker.
- Daily Errands: From grocery shopping to picking up dry cleaning, knowing your boot space helps you avoid multiple trips or the need for a larger vehicle.
- Travel and Vacations: Luggage, sports equipment, and travel gear all need to fit. Understanding your capacity ensures you can pack efficiently for your journeys.
- Purchasing Decisions: Before buying, comparing boot space across different CLA trims or even different Mercedes-Benz models helps you choose the vehicle that best suits your lifestyle.
- Hobby and Recreation: Golf clubs, camping gear, or even a medium-sized piece of flat-pack furniture might need to be transported. The CLA’s boot needs to be assessed for these specific needs.
- Resale Value: While not directly tied to measurement, vehicles that effectively cater to practical needs often hold their value better.
How is CLA Boot Space Measured?

The measurement of a car’s boot space is not a haphazard affair. It follows standardized procedures set by organizations like the Society of Automotive Engineers (SAE) in North America or through ISO standards globally. These standards ensure that measurements are consistent and comparable across different manufacturers and models.
The most common method involves filling the cargo area with standardized boxes or blocks of specific dimensions. These blocks approximate typical luggage items. Engineers then calculate the total volume that can be accommodated within the defined boundaries of the cargo space.
Standard SAE Measurement Methods
In the United States, the Society of Automotive Engineers (SAE) J1100 standard is widely used. This standard involves filling the cargo area with 1-gallon (approximately 3.785 liters) containers. Different methods within the standard account for variations:
- Usable Volume: This method fills the trunk with standardized containers up to the level of the boot lid’s lowest point or the height of the rear seatbacks. It represents what you can practically fit.
- Gross Volume: This measurement might include areas that are less accessible or at a different height than the ‘usable’ volume, providing a theoretical maximum.
For most consumers, the “usable volume” is the more relevant figure. Mercedes-Benz, like most global manufacturers, adheres to these international standards, often quoting figures in liters.
Key Factors Affecting Usable Space
While a number in liters provides a benchmark, the actual shape and features of the boot can influence how much you can fit:
- Wheel Arches: These intrusions into the cargo area can limit the width and depth of the space, making it difficult to fit wide or awkwardly shaped items.
- Seat Folding Mechanisms: The way the rear seats fold down (or if they split-fold) significantly impacts the length of the load bay.
- Height Restrictions: The height from the boot floor to the parcel shelf or rear window is also a limiting factor, especially for taller items.
- Access Opening Size: The shape and size of the trunk opening itself can be a constraint, even if the internal volume appears sufficient.
Mercedes-Benz CLA Boot Space Specifications by Model Year

The Mercedes-Benz CLA has evolved since its introduction, and with each generation and refresh, there can be slight variations in boot space. Understanding these specific figures helps differentiate models and understand their practical capabilities.
The CLA is generally available in two main body styles: the four-door coupe (sedan) and the Shooting Brake (station wagon), though market availability can vary. Naturally, the Shooting Brake variant offers a more generous and versatile cargo space.
CLA Sedan (Four-Door Coupe) Boot Space
The CLA sedan prioritizes sleek styling, which can sometimes mean a compromise on maximum cargo volume compared to a more traditionally shaped car. However, Mercedes-Benz engineers have maximized the available space efficiently.
- First Generation (C117, 2013-2019): Generally offered around 470 liters of boot space. This figure was competitive for its class at the time.
- Second Generation (C118, 2019-Present): The current generation typically boasts a boot space of approximately 460 liters. While a slight decrease from some earlier estimates, the usability and shape have been refined. Some sources also cite figures closer to 420-430 liters for the current generation, depending on specific measurement nuances and market variations. For precise figures pertaining to a specific model year and market, consulting the official Mercedes-Benz specifications for that region is always recommended.
CLA Shooting Brake Boot Space
The CLA Shooting Brake offers a more practical solution for those who need more utility from their compact luxury vehicle. Its extended roofline and more conventional tailgate significantly increase cargo capacity.
- First Generation (X117, introduced 2015 as part of C117 lifespan): The Shooting Brake variant generally provided around 495 liters of boot space with the rear seats in place.
- Second Generation (X118, 2019-Present): The current Shooting Brake is often cited with a boot capacity of approximately 505 liters. This extra volume, combined with a wider and taller opening, makes it a much more versatile option for larger items.
It’s worth noting that the AMG performance variants (e.g., CLA 35, CLA 45) may have slightly different cargo capacities due to modifications in suspension, exhaust systems, or underbody aerodynamics, though these differences are typically minimal for everyday use.
| Model Generation | Body Style | Approximate Boot Space (Liters) | Key Characteristics |
|---|---|---|---|
| First Generation (C117/X117) | Sedan | 470 L | Sleek profile, practical for a coupe. |
| Shooting Brake | 495 L | Increased practicality and volume; taller, wider access. | |
| Second Generation (C118/X118) | Sedan | 460 L (some sources 420-430 L) | Refined styling, still compact practicality. |
| Shooting Brake | 505 L | Generous capacity for its class, highly versatile. |
Measuring Your CLA’s Boot Space Yourself

While official figures are helpful, sometimes you need to know if a specific item will fit. Here’s a simple guide to getting a realistic sense of your CLA’s boot space capacity:
Essential Tools
- Measuring Tape: A flexible tape measure (preferably retractable) is essential.
- Notepad and Pen: To jot down dimensions.
- Object of Known Size: A large suitcase, a common-sized box, or even a children’s toy car with known dimensions can be helpful for comparison.
- Smartphone with Camera: To document your findings or share with someone if you’re unsure via messaging.
Step-by-Step Measurement Process
- Clear the Boot: Ensure the boot is completely empty. Remove any floor mats or cargo nets that might be in the way.
- Measure Width:
- At the narrowest point: Measure the distance between the wheel arches. This is often the most restrictive dimension for wider items.
- At the widest point: Measure across the boot floor behind the wheel arches.
- At the opening: Measure the width of the boot aperture, as this can be a limiting factor.
- Measure Depth:
- From the tailgate to the rear seats: Measure the distance from the closed tailgate (or boot lid) to the back of the rear seats.
- From the boot floor edge to the rear seats: This gives you a more practical depth for loading items, especially if there’s a lip.
- Measure Height:
- From the boot floor to the parcel shelf: This is the standard usable height.
- At the lowest point: Measure height between the wheel arches and the parcel shelf, as this is where taller items might get stuck.
- Maximum height: Measure from the boot floor to the highest point under the boot lid, with the parcel shelf removed.
- Consider Accessibility: Note the height of the boot lip and the angle of the rear hatch or tailgate. This affects how easily you can slide items in and out.
- Test Fit: If possible, place a large item you regularly need to transport (like a stroller or travel case) into the boot and see how it fits, noting any difficulties.
Example: Let’s say you measure your CLA’s boot and find:
- Width (narrowest): 100 cm
- Width (widest): 115 cm
- Depth (to seats): 80 cm
- Height (to shelf): 45 cm
This gives you a rough idea: you can fit items up to 100 cm wide, 80 cm deep, and 45 cm high, considering the wheel arches and parcel shelf. You can then compare these dimensions to an item you plan to buy or pack.
Maximizing Your CLA’s Boot Space: Practical Tips and Tricks

Even with a generous boot, clever packing can make a world of difference. Here are some expert tips to help you make the most of your Mercedes-Benz CLA’s cargo capacity:
Smart Packing Strategies
- Utilize Soft Bags: Duffel bags and backpacks conform to irregular spaces much better than rigid suitcases.
- Pack Vertically: Stand items upright where possible, especially if your boot has good height. This can save horizontal space.
- Fill Gaps: Use smaller, softer items like jackets, blankets, or groceries to fill any empty spaces between larger items. This prevents shifting and maximizes volume.
- Stack Wisely: Place heavier items at the bottom and towards the center of the boot for better weight distribution and stability.
- Tetris Your Load: Think of it like playing Tetris. Arrange items to slot together efficiently, rotating them to find the best fit.
Leveraging Your CLA’s Features
- Fold Down Rear Seats: For larger items, folding down the rear seats is the most effective way to expand your cargo space significantly. Consult your owner’s manual for the exact procedure for your CLA model, as it may involve safety catches or specific seat release mechanisms. Mercedes-Benz often designs their seats to fold nearly flat to create an extended load floor.
- Under-Floor Storage: Many vehicles have a hidden compartment beneath the boot floor. This is ideal for storing smaller, infrequently used items like a first-aid kit, emergency tools, or a small toolkit, keeping them out of sight and organized.
- Shopping Bag Hooks: Your CLA likely has hooks in the boot designed to secure grocery bags. Use them to prevent items from rolling around and to keep your food organized and upright.
- Cargo Nets and Organizers: Consider investing in a cargo net or organizer. These can help compartmentalize the boot, prevent items from sliding, and protect your vehicle’s interior. Mercedes-Benz often offers official accessories for this purpose, designed to fit perfectly.
Pre-Trip Planning
Before heading out on a significant road trip or a shopping spree:
- Make a List: Plan what you need to bring. This helps identify bulky items early on.
- Measure Your Item: If buying something new, get its dimensions beforehand. You can then compare these to your measured boot space.
- Visualize the Load: Mentally (or physically, with boxes) arrange items in the boot to see how they might fit best.
For specific measurements and fitting guides for various items, the SAE J1100 standard documentation provides in-depth details on how automotive volumes are calculated.
