The Mercedes-Benz X-Class pick-up truck has been spotted undergoing cold weather testing, and it appears to be edging closer towards production readiness. Though camouflage still conceals much of the front and some of the rear, some details can be gleaned from its present appearance, previewed by last year’s concept.

Up in front, the X-Class has a deeper front bumper and grille than that of the Nissan NP300 Navara upon which it is based, while the wheel arches appear to have less pronounced crease lines than on the Nissan. The X-Class also appears to do without the Navara’s upper crease lines, which on the Nissan, goes from the front fenders and into the front portion of the front doors.

The upper lip crease that is seen on the Navara’s load gate is also found on the Merc pick-up’s item, whilst the X-Class’s upper edge of its tray sides appear to have a slight gradient towards its cabin, while the same section along the Navara appears to be more level.

Under the bonnet, the X-Class is expected to utilise Mercedes’ own range of diesel engines, with the pick-up range topped by a 3.0 litre V6 variant, which produces 258 hp and 620 Nm of torque elsewhere in the Mercedes-Benz passenger car range.

Supplementing things will also be a range of four-cylinder diesel units, though it hasn’t been confirmed if these will also be made by the Stuttgart automaker. Mercedes’ own 4Matic driveline will also feature, making the use of the company’s own seven- or nine-speed automatics a possibility; electronic controls for the four-wheel drive, transfer case and centre and rear differential locks are expected.

Earlier, the company quoted a payload of 1.1 tonnes with a towing capacity of 3.5 tonnes for the X-Class. Like the Navara, the X-Class will feature five-link rear suspension with coil springs, for better ride comfort than other pick-up trucks. The upcoming German pick-up truck is expected to make its debut this year.
