Mitsubishi Triton vs Isuzu D-Max

What's the difference?

Apart from its distracting driver attention monitor, we can't see any major flaws that would detract from this vehicle’s comfort, practicality and performance when serving as either a utilitarian 4x4 workhorse or back-to-basics 4x4 dual cab for adventures off the beaten track.

The D-Max X-Rider has adequate appeal as a daily driver – it’s functional and comfortable – and it’s also working off a proven 4WD platform.

This mid-spec ute lacks the polish of higher-grade D-Max grades, but it may still entice those ute fans who want a workhorse with a tractable engine and don’t care at all about frippery.

Does that 2.2-litre engine add anything substantial to the package? No, and the potential fuel savings it represents don’t seem so likely as the 3.0-litre doesn’t use a lot more fuel than the 2.2-litre D-Max anyway – and the 3.0-litre version only costs another $2000 or so to buy.

The 3.0-litre D-Max remains the better option because while the 2.2L is effective off-road, it’s only reasonable in general day-to-day driving, as it lacks grunt and has to work that much harder and is that much noisier under load than the 3.0-litre in most driving scenarios, including 4WDing.

Our test vehicle rides on a compact 3130mm wheelbase and is 1865mm wide and 1795mm tall, which combined with a 12.4-metre turning circle makes it agile and easy to manoeuvre both on and off-road.

Speaking of which, its all-terrain credentials include 228mm of ground clearance, a useful 30.4 degrees approach angle (without bull-bar) and 23.4 degrees ramp breakover angle, with the departure angle dependent on the type of tray fitted. These numbers would be more than adequate for accessing rugged worksites.

Its front suspension is double-wishbone with coil-springs, paired with a robust leaf-spring live rear axle. Brakes are front discs and rear drums and it has electric power-assistance for the rack and pinion steering.

Looks are subjective of course but we reckon it has a robust and purposeful appearance in cab-chassis form, particularly with the accessories fitted to our example.

Chrome is all but extinct in its predominantly grey interior. However, hard surfaces on the centre console and door-pulls have a synthetic carbon-fibre finish, which adds a touch of style to a low-maintenance cabin that won’t get trashed by spilled coffee or muddy boots.

You also won’t find fancy features like digital instruments (it has analogue speedo/tacho) or an electronic handbrake (this one’s the good old manual lever). Plus there’s physical dials for audio volume/tuning and ‘piano key’ buttons for the cabin’s climate control, which ensures no distracting touchscreen prompts when driving.

Nothing much – if anything at all really – is different about this D-Max’s exterior compared to others in the stable.

Sure, the X-Rider has a tweaked front grille, 17.0-inch gloss black alloy wheels and black sports bar but those elements are mere frippery on top of what is already a tidy looking package.

The D-Max X-Rider is 5205mm long (with a 3125mm wheelbase), 1870mm wide and 1785mm high.

Inside, it is a clear uncluttered space, which is spot-on for this ute and part of the line-up’s rough charm.

The D-Max retains even an undeniable robust presence when compared to the more stylish Mazda BT-50 and Ford Ranger, or even rivals such as the Toyota HiLux.

With a kerb weight of only 1993kg (without tray) and 3200kg GVM, our test vehicle has a 1207kg payload rating. However, after you add the combined weight of its steel tray and other accessories (417kg), the payload rating is reduced by the same amount to 790kg. Even so, that still leaves a sizeable weight capacity for up to five tradies and their tools.

It’s also rated to tow up to 3500kg of braked trailer but with its 6250kg GCM (or how much it can legally carry and tow at the same time) the payload would have to be reduced by 450kg (from 790kg to 340kg) to avoid exceeding the GCM.

In real-world use it’s unlikely that many (if any) Triton owners would need to tow 3500kg but it’s important to be across these numbers to avoid overloading, which is dangerous and illegal.

The genuine accessory galvanised steel tray is internally 1650mm long and 1780mm wide. It has a robust checker-plate floor and a tube-frame front bulkhead with sturdy wire-mesh rear window protection.

There’s also swing-up load retainers on top of the tube-frame on each side, which when paired with the matching rear tube-rack accessory provides secure carrying space for extension ladders or long lengths of timber and PVC pipe/conduit.

There’s also external rope/strap rails along each side but like all steel trays we’ve come across there’s no internal load-anchorage points.

The driver and front passenger have access to a bottle holder and storage bin in each front door plus an overhead glasses holder and a large open compartment above the glovebox. The centre console offers more open storage plus two bottle/cupholders in the centre and a usefully-sized box at the back with a lid that doubles as a driver’s elbow rest.

The rear bench seat is comfortable and surprisingly spacious for tall people, given I’m 186cm and when seated behind the driver’s seat when set in my position, I have about 40mm of kneeroom and 60mm of headroom.

There’s also adequate head clearance for those seated in the slightly higher centre position, but the floor’s prominent transmission tunnel requires one boot either side and knees together between the front seat backrests.

And like all dual-cab utes short of a full-size US pick-up, rear shoulder room is squeezy for three adults, which is tolerable for short trips but a maximum of two adults would be ideal for longer drives.

Rear seat storage includes a bottle-holder and bin in each door plus pockets on each front seat backrest. The centre seat’s backrest also folds forward to serve as an armrest with dual bottle/cup-holders.

The bench seat’s base cushion is fixed, so unlike numerous rivals it can’t swing up and be stored vertically if more internal carrying space is required.

The X-Rider is a solidly spartan mid-spec ute.

From its myriad durable plastic surfaces through to its high-grade cloth seats, this ute is booted and suited for the dirt and dust of real day-to-day life.

Sure, it misses out on some of the more appealing aspects of higher-spec D-Max grades – including a bigger 9.0-inch touchscreen, built-in sat-nav, and less-tinny nine-speaker audio system – but it remains steadfastly true to the spirit of Isuzu’s workhorses where substance wins out over style every time.

As in any good ute, the cabin has a comfortably familiar feel about it and it’s an easy space in which to spend lots of drive time.

The interior is adequately spacious with supportive seats upfront and a reasonably comfortable bench-style pew for the three back-seat passengers.

While the touchscreen system is a bit clunky in operation – it takes some time and effort to navigate your way through menus and sub-menus to reach the area you want (usually the driver-assist tech that you want to adjust), the general mix of controls (on-screen and real switches, buttons and dials) are welcome.

There are plenty of charging options – a mix of USB-A, USB-C and 12V upfront, and USB-A for the back row – and storage places include recesses for your wallet, keys etc, a deep-ish centre console, as well as dual cupholders upfront and cupholders in the back seat’s fold-down armrest, and bottle holders in the doors.

Back-row passengers get USB ports, directional air-con vents and shallow under-seat storage.

The tub is 1570mm long (at floor level), 1530mm wide (1122mm between the wheel-arches) and 490mm deep. It has an under-rail tub liner, two cargo tie-down points, and it has tailgate assist.

Our test vehicle had a soft tonneau cover, which is annoyingly fiddly to close at the top edge of the tailgate.

Tub options for D-Max owners include a tonneau or roller cover (which offers at least some degree of security from thieves, and protection from rain, mud, snow etc), or an Isuzu or aftermarket canopy, although a canopy impacts the versatility of the load space because once it’s an enclosed area it makes it more difficult to carry long, awkward and/or large loads in the tub.

The D-Max X-Rider is part of a nine-variant 4x4 line-up; there are five 4x2 variants. Some D-Max variants are not offered with the 2.2L four-cylinder turbo-diesel engine, while some are not offered with the 3.0-litre four-cylinder turbo-diesel engine – check with your dealership for clarification.

The 2.2L D-Max X-Rider crew cab ute (our test vehicle) has an RRP of $59,500 before on-road costs (at time of writing), with special offer drive-away pricing of $56,990, depending on location.

Our test vehicle has some accessories onboard including rubber cabin floor mats ($229.98), tow bar wiring harness – 12-pin flat ($490), tow bar and tongue kit ($1310), and an electric brake controller ($999.75), so, with accessories stamp duty ($151.49) also added to the price, the test vehicle costs about $60,170 drive-away.

Standard features include an 8.0-inch multimedia touchscreen system (with wireless Apple CarPlay and Android Auto), a 4.2-inch driver display, six-speaker audio system, full suite of driver-assist tech, and more.

The X-Rider also has a black sports bar, revised front grille and 17.0-inch gloss black alloy wheels. 

Exterior paint choices include Sunstone Orange mica, Moonstone White pearl, Basalt Black mica, Wolfram Grey metallic (on the test vehicle) or Mineral White. Premium paint costs $695.

Its price-tag may put it up against the likes of Toyota HiLux, Ford Ranger and its mechanical twin, the Mazda BT-50, and it manages to hold its own against those in terms of value for money.

The Triton’s 2.4-litre four-cylinder diesel engine is equipped with two turbochargers that work in sequence to boost efficiency, with the smaller one providing fast response at low rpm and the larger one optimising performance at higher rpm. The result is 150kW of power at 3500rpm and torque peaking at 470Nm between 1500-2750rpm, using AdBlue to minimise emissions.

It’s paired with a six-speed torque converter automatic that offers the choice of sequential manual shifting, which can be preferable when hauling and/or towing heavy loads, particularly in hilly terrain.

The 4x4 system is dual-range, part-time offering 2H (2WD High Range), 4H (4WD High Range) and 4L (4WD Low Range) controlled by a dial on the centre console. However, you need to step up to the GLX+ to get a rear diff-lock.

The 2.2L D-Max X-Rider has a 2.2L four-cylinder turbo-diesel engine producing 120kW at 3600rpm and 400Nm between 1600-2400rpm and it’s matched to an eight-speed automatic transmission.

While the 3.0-litre D-Max has always been mostly unstressed in the majority of driving scenarios – even low-range 4WDing – the 2.2-litre feels underpowered.

It is noisy, especially under heavy acceleration or load. It has to work harder than the 3.0-litre and, again, it is noisy. Yes, the 3.0-litre D-Max is gruff, but there's a strained edge to the roughness in the 2.2-litre that is very noticeable while driving on sealed surfaces at speed.

Have I mentioned that it’s noisy?

The good news is that the eight-speed auto feels as slick and as smooth in application here as it does in this ute’s stablemate, the MU-X, and, as such, it feels right at home in this ute.

This D-Max has a part-time 4WD system which includes a dual-range transfer case (with high- and low-range 4WD) and a rear diff-lock. The driver is able to shift from 2H (two-wheel drive, high-range) to 4H (4WD high-range) while on the move up to speeds of 100km/h. The diff-lock may only be engaged when the vehicle is in 4L (4WD low-range).

The D-Max also has a switchable terrain mode system which tweaks the engine, transmission and traction control to suit the driving conditions. 'Rough Terrain' mode, like a steroids-enhanced off-road traction control, is king of these modes when you’re off the bitumen.

Mitsubishi claims official combined average consumption of 7.7L/100km but the dash display was showing 9.9 at the completion of our 316km test, which included the usual mix of suburban, city and highway driving of which about one third of that distance was hauling its maximum payload.

Our own consumption figure, calculated from fuel bowser and tripmeter readings, came in higher again at 10.7L/100km which is on the borderline of the usual 2-3L/100km discrepancy between manufacturer claims and real-world consumption.

So, based on our own numbers, the test vehicle should have a real-world driving range of around 700km from its 75-litre tank.

Official fuel consumption for this D-Max is 7.1L/100km.

Real-world fuel consumption on this test was 8.4L/100km.

The D-Max has an 76-litre fuel tank, so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 904km.

But remember, your fuel consumption has the potential to be much higher than our tested figures because chances are you'll have family, friends, pets, camping gear, water craft, the whole kit and caboodle on board. I only carried vehicle recovery gear, MaxTrax, and a first-aid kit, so I didn’t have a huge amount of weight on board.

Large assist-handles on the A (and B) pillars, combined with the accessory side-steps on our example, make it easy to climb aboard and find a comfortable driving position.

The unladen ride is firm, as you’d expect given its 6.0-tonne-plus GCM rating, but it’s still supple enough to soak up the bumps without the harsh kidney-belting ride suffered in some cab-chassis one-tonners we’ve tested.

This is no doubt helped by the accessories fitted, which provide more than 400kg of additional sprung weight to engage the heavy-duty rear springs and improve the ride quality. That’s something to keep in mind if you often drive unladen.

The steering is firmly weighted and the brakes have good response, with the rear drums offering a terrier-like bite when the manual handbrake is applied on steep hills with a heavy load on board.

The four-cylinder 2.4-litre diesel, with its sequential turbocharging and strong outputs, provides energetic all-round performance with efficient gearing that ensures its operating within its peak torque band most of the time.

However, at highway speeds it does tend to hold top gear for too long, when the engine has dropped below 1500rpm and is clearly wanting a downshift.

To test its payload rating, we strapped 650kg on the tray which when combined with accessories and crew was right on the weight limit. The stout rear springs compressed only 25mm under this load, leaving ample bump-stop clearance that assured there was no bottoming-out on our test route.

The Triton handled this task with competence, maintaining good performance and chassis stability. It easily hauled this load up our 13 per cent gradient, 2.0km set climb at 60km/h, with the six-speed auto self-shifting down to third gear and 2500rpm which was comfortably within its peak torque band. Engine braking on the way down was also commendable.

Our only gripe is the driver distraction monitoring system which is still too reactive in certain situations, like scratching an itch below my eye even though I was looking straight ahead while doing it. Even though Mitsubishi has tried to improve this system, it needs more refinement, as it detracts from an otherwise positive driving experience.

The D-Max has for some time been regarded as reasonable on-road - comfortable, composed, and somewhat refined for a 4WD ute.

However, while the 3.0-litre D-Max is gruff and laggy and yet retains a certain rough charm, the 2.2-litre version is simply noisy and sluggish and forgoes the charm.

This D-Max has to work harder than the 3.0-litre does, and it makes that abundantly clear with a caustic edge to the roughness in the 2.2-litre that is very noticeable on road.

It’s slow off the mark, exhibiting a disconcerting lag under heavy throttle from a standing start. And it’s far from the most dynamic vehicle to drive. But its low-key appealing tractability almost manages to negate these flaws – but not quite.

As mentioned earlier, the eight-speed auto is a smooth operator, micro-managing the engine as best it can.

When it comes time to leave the bitumen and hit the dirt, this D-Max – with a kerb weight of approximately 2010kg and a not-insubstantial turning circle of 12.5m – feels nimble on bush tracks and it is still very capable.

Even though the 3.0-litre D-Max is not the ute segment’s torquiest, it offers plenty of pulling power across a broad rev range – with peak torque between 1600rpm and 2400rpm – and it delivers that torque in an even-handed way. It still has a decent amount of low- and mid-range torque, which makes dirt-road cruising and low-speed 4WDing easy.

One of the major differences between the two engines is that the 2.2-litre D-Max has to work that much harder than its stablemate, and, as a result, it’s noisier and harsher.

However, this D-Max has part-time 4WD (with high- and low-range 4WD), a rear diff lock and an effective off-road traction control system (which has been recalibrated over the years), so it still retains all of that off-road capability the D-Max has built its reputation on.

Ground clearance is 235mm and wading depth is 800mm, so there’s an adequate amount of clearance for most reasonable off-road challenges (for standard unmodified vehicles) and its listed off-road angles of 26.9 (approach), 23.9 (departure) and 23.3 (ramp-over) all check out.

This ute’s wheel travel – how far the axle can move up and down relative to the chassis – has more than an adequate amount of flex, stretching its tyres close, if not all the way, to the dirt.

This D-Max’s 255/65 R17 all-terrain tyres (Dunlop Grandtrek AT25s on 17” x 7” alloy rims) are adequate for off-roading but an even more aggressive set of all-terrains would boost this ute’s off-road capability.

The general rule applies here as with any standard unmodified off-road vehicle: drive with care, control and consideration and you shouldn't have any trouble tackling light to moderate 4WDing in this ute.

The 2.2L D-Max has a listed kerb weight of 2010kg. In terms of packability, gross vehicle mass is 3100kg, so theoretically this ute has a payload of 1090kg (GVM - kerb weight = payload), but Isuzu has based that figure on the cab-chassis variant’s weight.

This ute’s payload total – after the weight of onboard accessories and a 200kg total of driver and passengers are subtracted – is 818kg, according to Isuzu’s own payload calculator.

The 2.2L D-Max can legally tow 750kg (unbraked trailer) and 3500kg (braked). It has a listed gross combined mass of 6000kg.

The D-Max has the maximum five-star ANCAP safety rating from testing in 2022.

Standard safety features include eight airbags - dual front, dual front side, dual full-length curtain, front knee and centre (far-side) - and a comprehensive suite of driver-assist tech including auto emergency braking (AEB), adaptive cruise control, lane keep assist, lane departure warning, a digital reversing camera and a tyre-pressure monitoring system.

The driver-assist tech, while mostly effective, can be annoying (for example, misreading/misjudging speed limit signs) and over the top in its reactions (with auto emergency braking biting hard out of the blue when it really needn’t), and it takes some time to work your way through the on-screen menus and sub-menus in order to switch off ADAS alerts.

It comes with a five-year/100,000km standard warranty, or 10 years/200,000km if serviced at Mitsubishi dealers.

Scheduled servicing is every 12 months/15,000km whichever occurs first. Pricing is capped at $6860 for 10 scheduled services up to 10 years/150,000km, or an average of $686 per service.

Mitsubishi currently has more than 200 dealers across its national network that spans metro, rural and regional areas. Mitsubishi dealerships are also service centres.

The D-Max has a six-year/150,000km warranty and seven years of roadside assistance. Unlimited kilometres in the warranty would be welcome.

A free inspection is pencilled in at the three-month or 3000km mark (whichever occurs soonest), then service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped-price servicing covers the first five scheduled services (up to five years/75,000km – whichever occurs soonest) at a cost of $489 for each service.

Isuzu Ute Australia has a nationwide network of more than 160 dealer sites.
