Mercedes A-Class Boot Size: 370 Litres — Compact Luxury With a Practical Load Floor
The Mercedes A-Class W177 offers 370 litres — less than rivals on paper, but a flat floor, generous 76 cm aperture height, and wide opening make it easier to use than the numbers suggest.
The Mercedes-Benz A-Class (W177, 2018–present) is the standard vehicle in the "premium compact" or "full-size compact" rental category. Its 370L boot volume is the lowest in its class — less than the Audi A3 (380L) and significantly less than the BMW 1 Series (380L). But the A-Class has one practical advantage: a flat, low load floor with minimal sill height, and a 76 cm aperture height that allows large check-in suitcases to load upright without tilting.
Mercedes A-Class Boot Dimensions (W177, 2018–present)
| Measurement | Value |
|---|---|
| Boot volume | 370 litres |
| Floor width | 105 cm |
| Load depth | 55 cm |
| Internal height | 60 cm |
| Aperture width | 94 cm |
| Aperture height | 76 cm |
The 55 cm load depth is the main constraint — shallower than the Karoq (67 cm) and Niro (71 cm). This limits how many bags you can stack front-to-back. But the 105 cm floor width is the widest in its class, meaning two medium suitcases fit genuinely side by side. The 76 cm aperture height means large suitcases (76 cm tall) just clear the lip — they slide straight in at the vertical, no tilting needed.
Does Your Luggage Fit in a Mercedes A-Class?
| Bag type | Fits? | Notes |
|---|---|---|
| Cabin bag (56×36×23 cm) | ✅ Yes | No issues. Loads flat or upright. |
| Medium check-in (66×46×26 cm) | ✅ Yes (flat or angled) | 66 cm slightly exceeds 60 cm height — load flat or at an angle against the seat. Two fit side by side on the wide 105 cm floor. |
| Large check-in (76×51×28 cm) | ✅ Yes (flat) | 76 cm passes the 76 cm aperture exactly — enters cleanly. Loads flat (60 cm internal height). |
| 2× medium + 1× cabin | ✅ Yes | Two mediums side by side on the wide floor, cabin on top. Standard couple-plus-one combination. |
| 2× large check-in | ⚠️ Tight | Side by side is possible on the 105 cm floor. 55 cm depth is the limit — snug fit. |
A-Class vs. Audi A3 vs. BMW 1 Series
All three premium compact hatches sit in the same rental category. The A-Class leads on floor width (105 cm) and aperture height (76 cm); the Audi A3 has slightly more volume (380L) but a narrower floor; the BMW 1 Series offers 380L with a similar aperture. For pure luggage practicality the A-Class is the best loading experience; for raw volume the A3 and 1 Series edge ahead. None of the three is the right choice for more than two travellers with large luggage — in that case, step up to a compact SUV.
