Mercedes-Benz X-Class vs Mazda BT-50

What's the difference?

The X was an opportunistic shot at a market segment new to Benz. With even apprentices able to afford to buy a well-specced Hilux, it's become harder to separate the foreman from the kids. I, like Mercedes, thought this would be the boss's car. Mercedes saw the gap and went for it, thinking it could grab sales from top end utes from VW, Toyota and Ford, while maybe saving a few folks from buying a RAM or an F150.

The problem is, the target market knows its utes. And in a rough-and-tumble workplace, the perception is that if you've spent up big on this Merc, you've actually just paid too much for a Nissan Navara. Still, like those flawed movies I enjoy, the X-Class is a fine thing - and I don't blame Mercedes for trying. It just costs too much, and yet isn't Mercedes enough to justify that price.

The MY25 Mazda BT-50 benefits from its robust Isuzu underpinnings to excel in this dual cab-chassis configuration, particularly with Mazda’s premium heavy-duty aluminium tray as fitted to our test vehicle. Fact is, apart from the big drop in payload required to tow 3500kg (but it’s not alone there) it’s hard to find any major flaws. Overall, it’s an excellent workhorse that would be well suited to a multitude of tradie tasks. 

Despite being a Japanese ute in drag, the X-Class isn't immediately rumbled as resembling a Nissan, which certainly should count in its favour. Everyone who asked about it had little idea it wasn't a Daimler from the ground up, until you pointed out various details. Up here in the higher reaches, it's a really quality-looking thing, with beautiful paint and enough differentiation to make it look like a Merc. The headlights do seem a tad small next to the rest of the Mercedes range, but the whopping great three-pointed star in the grille leaves no one in doubt. 

It's fairly tasteful in silver, too, and with a few carefully chosen options it looks pretty tough.

Once you're inside you see where it starts to get confused about itself. The hard, scratchy plastic dash pokes out from behind a huge slab of metallic trim. The centre console is clearly a brother from another mother, as is the overall dash layout. The cabin lacks the thoughtfulness and quality of a Mercedes design - you can't just slap on those signature air vents and expect to get away with it. Every piece that comes from Mercedes appears glued on, and it's jarring. 

This might have been less of an issue if the car was significantly cheaper and not likely to be purchased by people who are familiar with the brand.

It must be said that Mazda’s stylists did a commendable job with the third-gen BT-50 when it launched in 2020. Five years later it still looks fresh and we’re yet to find anyone who doesn't like its styling, which is in stark contrast to its polarising predecessor.

Its exterior sculpting embodies Mazda’s design language to maintain a strong family resemblance to the popular CX line of SUVs, yet does not detract from the tough and purposeful appearance expected of a 4x4 ute.

The MY25 facelift includes a newly designed front bumper, radiator grille and unique LED headlights. At the rear, pick-up models incorporate what Mazda describes as a ‘mountain-inspired ridged design’ along the bottom edge of the tailgate, along with new LED tail-lights and a larger Mazda logo.

Apart from the mountain-inspired ridged design, also evident on the glove box lid, the latest XTR interior is largely unchanged, blending different shades of grey with satin chrome highlights on the dashboard and door linings, contrasting fabric seat trim, exposed stitching on seams and adjustable centre console air conditioning vents for rear seat passengers.

I really can't imagine how anyone signed off on the most annoying features of the X. Front-seat passengers get a solitary, shallow cupholder (the second one is unusable), and big door bins that could hold a bottle if you didn't mind it getting smashed from sliding around (they're unlined), and nowhere to put your phone. Like, nowhere, except maybe the glove box. Even the centre console bin is shallow and not much good for anything, apart from as an armrest.

The front seats are reasonably comfortable but the rears are way too high (in the name of a better view) and rammed hard against the rear bulkhead. The rear doors are also pretty narrow, so entry and egress can be a bit of a challenge if you're large or toddler small. Once you're in the seats, legroom is limited and headroom marginal. At least you get air-conditioning vents, but you don't get an armrest in the rear. On a nearly $80,000 ute. Even the dark-ages Colorado has one of those.

Anyway, that's enough said about the interior flaws.

The tray is a big boy, but it's worth knowing that the roller cover does rob a bit of space, as it does on any ute. The optional tray liner looks good and with Mercedes-Benz stamped in it, reminds you again what you've got. All told, it's 1581mm long, 1560mm wide (1215mm between the wheelarches) and you can load up nearly a tonne of people and things into the X350. You can also tow a massive 3500kg braked and still be able to carry a payload of 490kg. Gross vehicle mass is 3250kg (tare is 2190kg).

Our test vehicle’s 1910kg kerb weight and 3100kg GVM results in a meaty 1190kg payload rating. However, that drops to 891kg after you deduct the combined weight of the premium heavy-duty aluminium tray (243kg), nudge bar (9.0kg) and towing kit (47kg).

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer but with its 6000kg GCM (or how much it can legally carry and tow at the same time), towing that weight would require a substantial 590kg reduction in payload to avoid exceeding the GCM.

Even though few (if any) BT-50 owners would need to tow 3500kg, it’s important to be aware of these numbers if the need arose, to ensure the combined weight of your vehicle and trailer does not exceed the legal limit.

The premium heavy-duty aluminium tray from Mazda’s genuine accessories range is a nice bit of kit with its Mazda-branded tailgate decals and mudguards.

The tray is almost square with internal dimensions of 1800mm length and 1777mm width. And it has numerous internal load-anchorage points, external rope-rails and a sturdy mesh-style rear window protector, plus removable ‘quick-lock’ ladder racks with fold-down load retainers up top.

There’s also a 1500mm-long underbody drawer with adjustable internal dividers and a four-stage incremental locking system. An HDP (High Density Polyethylene) 25-litre water tank complete with tap and handwash bottle-holder resides under the right side of the tray, with a sizeable and lockable HDP toolbox under the left side.

The driver and front passenger have comfortable bucket seats and the rear bench is also accommodating, with ample head and kneeroom even for tall people.

However, shoulder room would be tight for three big tradies, so like most dual cabs short of a full-size US pick-up it’s tolerable for short trips as a five-seater but works best as a four-seater for longer drives.

Cabin storage includes a large-bottle holder and bin in the base of each front door and the dash has upper and lower glove boxes, an overhead glasses holder and a pull-open compartment to the right of the driver’s knee for small items.

The centre console has an open tray at the front, dual small-bottle/cupholders in the centre and a small box at the rear with a contoured lid that doubles as a driver’s elbow rest.

Rear passengers get a large-bottle holder and small bin in each door, plus storage pockets on the front seat backrests and a pair of pop-out cupholders in the fold-down centre armrest.

The 60/40-split rear bench seat’s cushions can also swing up and be stored vertically if more internal load space is needed. This also reveals two underfloor compartments with lids for keeping valuables out of sight.

Our test vehicle is the XTR cab-chassis, which is available only with a 3.0-litre, four-cylinder, turbo-diesel engine and six-speed automatic transmission, for a list price of $59,650.

The XTR is an upgraded version of the base model XT cab chassis equivalent which lists at $54,620, so for the extra $5030 you’ll pay for the XTR the standard equipment list expands to include 18-inch machined alloy wheels with 265/60 R18 tyres (and a full-size alloy spare), LED headlights/DRLs/front fog lamps, side-steps and power-fold mirrors.

The XTR cabin also comes standard with carpet, a leather-wrapped steering wheel and shift knob, three USB-C ports and a 12-volt socket, fold-down rear centre armrest, eight-speaker audio with digital radio and wired/wireless Apple CarPlay and Android Auto connectivity.

The cabin has smart keyless entry (with auto central-locking when you walk away from the vehicle), dual-zone climate control and 9.0-inch multimedia colour touchscreen, now thankfully with physical volume and tuning dials.

In addition to the facelifted styling, is updated software for the touchscreen which includes tyre pressure monitoring and various off-road-focused displays. The driver also gets a new 7.0-inch customisable 'Multi-Information Display' (MID).

Our example, finished in optional 'Ingot Silver Metallic' ($695), is also fitted with several items tailored for tradies from Mazda’s genuine accessories range, including a premium heavy-duty aluminium tray ($7888), SP nudge bar ($1432) and 3500kg tow pack ($1389) which combined add more than $11K to the price.

The X350d has something very Mercedes about it - the engine and transmission package. With 3.5-litres of turbo-diesel V6, you get 190kW at 3400rpm and a thumping 550Nm between 1400 and 3200rpm. These kind of figures at least put it up there with the brawnier VW Amarok.

Feeding the power to all four wheels is Mercedes' own seven-speed automatic. A centre diff apportions power front to rear and you have a choice of three modes - automatic, high range and low-range.

The BT-50’s drivetrain, shared with its D-Max donor, comprises Isuzu’s proven Euro 5-compliant 3.0-litre, four-cylinder, turbo-diesel that produces 140kW of power at 3600rpm and 450Nm of torque between 1600-2600rpm.

This is paired with an Aisin-sourced six-speed torque converter automatic featuring ‘intelligent’ protocols that prompt downshifting to assist with engine-braking on steep descents (great when towing) and overdrive on the top two ratios optimises fuel economy during highway driving.

It also offers the choice of sequential manual-shifting, which can be handy when hauling and/or towing heavy loads particularly in hilly terrain.

The part-time, dual-range 4x4 transmission features 2.482:1 low-range reduction and a switchable locking rear diff

The X350d did pretty well in the week I had it - the official figure of 8.8L/100km was never going to happen but with a long motorway run to the Blue Mountains and the rest bashing about town, the 10.5L/100km I did achieve without trying was not bad at all. The 80-litre tank should give you a decent range of 750km, or thereabouts.

Mazda claims an official combined cycle (urban/extra-urban) average of 8.0L/100km and the dash display was showing 10.2 at the completion of our 369km test, which comprised a mix of city, suburban and highway driving of which about one third was hauling a near-maximum payload.

Our own figure, calculated from fuel bowser and tripmeter readings, was slightly higher again at 10.6L/100km but still within the usual 2.0-3.0L/100km discrepancy between official and real-world figures and not bad for a two-tonne-plus 4x4 ute.

So, based on our figure, you could expect a realistic driving range of around 700km from its 76-litre tank.

One of the weirder things to make it into the X-Class is the world's second most irritating column stalk, which is asked to pack in indicators, headlights and wipers. Thankfully, the world's most irritating column stalk, the Mercedes automatic shifter, wasn't inflicted on the X-Class. But the obvious problem is the key, which clearly isn't a Mercedes unit - even the star is ill-fitting and will probably fall off after a while. This is not a premium experience.

Thankfully, the big turbo-diesel wipes away a lot of the complaints about this car not being Mercedes enough. Brawny and super quiet (twin balance shafts will do that), the X is a very easy car to live with. While not especially lively, it's easygoing in the city and very refined.

On the open road it cruises almost silently and the ride is way above what you might expect from an unloaded tradie-mobile. It doesn't feel as high as some utes, which makes it feel a bit more car-like, and will no doubt appeal to some who might have to swap in and out of a traditional SUV and into the X, for whatever reason.

It is by far the most civilised ute I've ever driven and was worlds away from the Colorado I drove last week, to the point where I could almost - almost - see a justification for the unbelievably hefty price tag.

Credit for the refined ride and handling goes to the coil-spring rear end, much maligned in some quarters. While that style of suspension is not the ultimate in load-lugging, it's way more comfortable for passengers and, given the likely buyer profile, probably more agreeable than a cart-sprung rear-end.

I would cheerfully drive long distances in the X and it feels like it could go anywhere.

The cabin is spacious and, with side-steps plus large handles on the front windscreen pillars, it’s easy to climb aboard and find a comfortable driving position.

All-around vision is good and active driver aids like blind-spot monitoring, rear cross-traffic alert and reversing camera instil confidence, particularly when hauling taller loads that block rear vision through the central mirror.

The engine is responsive in city and suburban use, thanks largely to its broad spread of torque across a 1000rpm-wide band from 1600-2600rpm that showcases its useful flexibility. The six-speed automatic has well-spaced ratios and shift calibrations that feel like they get the best out of this engine, either unladen or when hauling heavy loads.

It feels well-planted on the road and displays sure-footed handling if driven at appropriate speeds for a high-riding 4x4 ute, combined with excellent steering feel and responsive braking.

The unladen ride is firm, as you’d expect given the heavy-duty rear suspension unique to cab-chassis models, but the combined sprung weight of the tray and tow bar ensure it’s not too harsh.

To test its payload rating we strapped 830kg onto the load tray, which with driver and half a tank of diesel was a snip under its GVM limit. Even so, the rear leaf-springs only compressing 40mm under this loading, which left more than 40mm of bump-stop clearance that ensured no bottoming-out on our test route.

It hauled this big load with competence and a smoother ride quality, given the large increase in sprung weight allowed the heavy-duty rear suspension to do what it’s primarily designed to do.

There was also minimal effect on steering and braking response and the engine’s ample torque was not phased by this payload, particularly on our 13 per cent gradient, 2.0km-long set climb at 60km/h.

Engine-braking on the way down was also robust, highlighting the advantage of larger displacement engines (3.0-litres-plus) on overrun when restraining heavy loads on steep descents.

It also has low engine, tyre and wind noise at highway speeds, where the engine requires less than 2000rpm to maintain 110km/h thanks to its overdriven top gear with full torque converter lock-up.

This ensures the BT-50 is a comfortable and economical highway cruiser, with average fuel consumption that quickly drops into single figures on long hauls.

It has a maximum five-star ANCAP rating originally awarded in 2020 and updated in 2022 in accordance with D-Max upgrades.

The benchmark safety menu is packed with passive and active safety features highlighted by multiple airbags including full side-curtains and the latest in low/high speed AEB with pedestrian/cycle/motorcycle detection, lane-keeping, blind-spot monitoring, rear cross-traffic alert, reversing camera, trailer sway control, tyre pressure monitoring and much more.

For junior tradies there are ISOFIX child-seat anchorages and top-tethers for the outer rear seating positions.

Mercedes offers a three year/200,000km warranty for the X, which isn't too bad. It also throws in roadside assist for the duration. Also worthy are the 12 month/20,000km service intervals. 

A basic capped-price service scheme will hit you for $1950 (pre-paid) or $2,555 if you pay when you front up for each of the three services covered. The servicing isn't super-cheap, as you can see, but at least you know what you're up for.

Our test vehicle comes with a five-year/unlimited km warranty.

Scheduled servicing is every 12 months/15,000km whichever occurs first.

Mazda’s ‘estimated service cost’ for the first five years/75,000km totals $2547 which is an average of $509 annually.
