Full details of the Mercedes X-Class load area and carrying capability, including load bed dimensions, payload rating and maximum towing capacity.

Mercedes-Benz X-Class (17-20) capacity & size

3.9 out of 5 3.9

All the the exterior and load area dimensions for the Mercedes X-Class pickup are listed on this page.

Unsurprisingly, the X-Class has very similar dimensions to that of the Nissan Navara, with which it shares its chassis and other components.

However, just like so many other things about these two pickups, they aren’t exactly the same.

Mercedes X-Class exterior dimensions

The X-Class’s exterior dimensions are marginally different to the Navara’s, but not to the extent that they would make any tangible difference to how you would be able to use either vehicle.

Mercedes X-Class size
Exterior length (mm) 5,340
Exterior height (mm) 1,819
Exterior width, mirrors folded (mm) 1,916
Exterior width with mirrors (mm) 2,113
Wheelbase (mm) 3,150
Front overhang (mm) 888
Rear overhang (mm) 1,302

To be clear, since you presumably don't have the Navara's exterior dimensions memorise, the Mercedes is ever so slightly longer, taller and wider - but we are only talking a few millimetres in every instance.

It may also be worth noting that chief rival the VW Amarok is wider still.

Mercedes X-Class load area dimensions

These are the X-Class load bed dimensions, which again differ slightly to those of the Navara.

Mercedes X-Class load bay dimensions
Maximum load length (mm) 1,587
Maximum load width (mm) 1,560
Width between wheelarches (mm) 1,215
Sidewall height (mm) 475
Loading height from ground (mm) 854


Did you spot the difference? The X-Class’s load area is 50mm longer than the Navara’s – though all of the other dimensions are the same.

Mercedes X-Class load area accessories

Mercedes has designed a whole range of accessories in-house, from roll bars to soft and hard load covers.

And in addition to offering a regular bed liner, Mercedes again borrows from the Navara to make available versatile load lashing rails for the floor and sides, plus a bed divider system and a storage box.

Mercedes-Benz X-Class (17-20) payload, weight & towing

3.9 out of 5 3.9

The X-Class matches the 3.5-tonne towing capacity of the Navara and all the other best-in-class pickups.

As for payload, the X-Class is right up with the best in the sector, with ratings stretching up to 1,140kg.

The X 220 d in Progressive trim is rated to carry the most, with an official gross payload of 1,140kg. The lowest rating for the four-cylinder models is the X 250 d in Pure trim, which offers 1,112kg of carrying ability.
