Mercedes-Benz X-Class X220d RWD 2018 review

Benz has re-engineered the Navara's steel ladder-frame chassis for greater rigidity and topped it with a restyled body that's 85mm longer and 126mm wider with a new M-B interior. There are also new front suspension components and a new coil-spring multi-link live rear axle assembly with disc brakes, which result in track width increases of 82mm front and 75mm rear (compared to RX Navara 4x2).

These engineering changes, combined with revised springs, shocks, anti-sway bars and steering, result in sure-footed handling with sharp steering response, excellent ride quality and a feeling of solidity that are all X-Class strengths. However, they have also resulted in a hefty 236kg weight gain.

The X-Class Pure 4x2 rides on a 3150mm wheelbase with a 5340mm overall length, 1916mm width and 1839mm height. In comparison to Ford's Ranger, which is considered the 'bigfoot' of Aussie dual cabs, the X-Class is 70mm shorter in wheelbase and 22mm shorter overall, but 56mm wider, 24mm taller and lineball on turning circle at 12.8 metres. So, like the Ranger it's quite a large and imposing vehicle.

The X-Class Pure 4x2 rides on a 3150mm wheelbase with a 5340mm overall length, 1916mm width and 1839mm height.

Critical rough road credentials include 222mm of ground clearance with 30 degree approach and 25 degree departure angles. Its wading depth of 600mm is better than Amarok (500mm) but considerably less than Ranger (800mm).

It's nice to see sizeable grab handles on the window pillars for front and rear passengers and the driving position is pretty good. However, the Pure's front seats lack sufficient lumbar support and the base cushion (at least the driver's) needs some rake adjustment, as it can feel like you're sliding off the front at times.

For such a sizable vehicle we're surprised by how cramped the rear seating is for taller adults in terms of length and height, with knees touching the front seat backrests and, thanks to the higher 'grandstand' style rear seating, heads touching the roof lining. The rearward location of the B pillar also makes for quite tight entry and exit for those long of limb and large of shoe.

Mercedes Benz's official combined figure is 7.6L/100km and the instrument display was showing that figure at the end of our test, which covered more than 660km on different roads (sealed and unsealed) and with a variety of loads, including our usual GVM run.

By comparison, our figures calculated from trip meter and fuel bowser readings came in at 9.0L/100km. Any dual-cab ute, particularly one this size, which can deliver genuine single-digit fuel economy in 'real world' driving gets a big tick from us. Based on our figures, you could expect a realistic driving range of 850km-plus from its 80-litre tank, which is fuel efficiency with a capital E.

Deducting the 4x2 Pure's 2046kg kerb weight from its 3200kg GVM would normally equal a payload of 1154kg, but the official payload figure is 68kg under that at 1086kg, which is an extra safety margin should the payload (but not the GVM) be exceeded.

The Pure 4x2's braked towing capacity of up to 3200kg is less than the 4x4 models' 3500kg rating. Even so, its generous 6139kg GCM allows for a substantial 884kg payload while towing its heaviest trailer load, which is impressive.

The load tub is 1581mm long, 1560mm wide and 475mm deep, with 1215mm between the wheel arches ensuring it can carry an 1160mm-square standard Aussie pallet. As mentioned earlier, our test vehicle was equipped with the optional $490 rear window guard frame, which should not only be standard but also have tradie-friendly pivoting load retainers or 'book-ends' on each side for carrying long lengths of timber, PVC pipe, etc.

The test vehicle's adjustable load-securing rail system mounted near the top of the tub (as seen on Navara) works well for securing loads of matching height or more, but there also needs to be four tie-down points in each corner at floor level to secure lower loads as well. The absence of load retainers and floor level tie-down points are glaring omissions for such a work-focused vehicle.

With tradies in mind there's also a lack of cabin storage, limited to bottle holders and storage pockets in each front door, an overhead sunglasses holder and small glove box. The multimedia system's sizeable rotary controller and touch-pad occupy a big chunk of potential storage space in the centre console, which only offers a tiny front storage slot, single cup holder and small rear lidded box (and there's no box if you opt for the 1-DIN audio ports as fitted to our test vehicle).

Rear seat passengers get a bottle holder and smaller storage pocket in each door and the bench seat base pivots upwards to a vertical position if you want some extra internal cargo space. But there are no flexible storage pockets on the front seat backrests and no cupholders. This needs a re-think because you quickly run out of places to store things.

Maximum five-star ANCAP rating and first dual-cab ute to bring AEB to this segment gets a rare perfect score from us. Passive safety includes driver and front passenger front, thorax, side curtain and driver's knee airbags, child restraint top tethers plus iSize and ISOFIX anchorages on outer rear seat positions.

Active safety also includes lane-keeping assist and vital ute features like brake-force distribution, trailer stability assist, hill start assist and tyre pressure monitoring.
