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 new engine makes the D-Max a much more likeable ute than it already was, which is high praise.

It’s smoother and quieter and makes for a more pleasant drive. The added efficiency is a bonus both for your wallet and Isuzu’s emissions credits.

The 3.0-litre engine will probably remain the favourite, but anyone who test drives a 2.2L might even be tempted to opt for the smaller unit. Isuzu sure hopes so.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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.

The look of the D-Max depends on the grade you end up with, but the 2.2-litre SX and X-Rider variants down the lower end of the model-run are still pretty standard-looking utes. Inside and out.

You get fairly rugged styling that fits in for both work and play, and the interior is functional, if getting a little outdated. 

The black trim (and extra features) that comes with the LSM X-Rider as opposed to the SX is worth it if you’re keen to get a 2.2-litre-powered D-Max for the family rather than one for a fleet as it just elevates things slightly.

Inside, it also means nicer cloth, and not having the vinyl flooring looks a little less ‘farm ute’.

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 D-Max remains straight-forward inside, given nothing has changed with the update aside from the 2.2-litre engine and the addition of stop-start - there’s a button for that now.

The interior and usability of the D-Max, especially in the lower-end variants where the 2.2L engine is available, is focused on the basics.

Tech remains at a relative entry point, where the 8.0-inch screen and its software feel outdated but do everything you need. Plus of course there’s the phone mirroring workaround.

The D-Max is comfortable and spacious enough, there’s also physical buttons for everything including media and climate settings, and adjustability in terms of the seating position means not needing to reach.

In dual-cab versions, there’s enough space for an adult to sit in the second row behind another adult, so the D-Max also holds its own as a family hauler. Tick.

Importantly, Isuzu is now able to claim a 3500kg braked towing capacity across the full D-Max range thanks to the new 2.2-litre engine.

Pricing is up across the board for D-Max (and its MU-X sibling) regardless of drivetrain, but we’ll stick to the 2.2-litre variants here to stay on track.

Most of the lower-level D-Max variants are $1500 more than the previous equivalent, and with the manual gearbox dropped, the cheapest grade is the 4x2 single-cab chassis SX with a 2.2L engine at $36,200 before on-roads.

You can get the SX in crew-cab with a chassis or ute back in either 4x2 or 4x4 with a 2.2L engine, which is also available in the LSM X-Rider 4x4. 

That one will set you back $59,500, which is still far from the most expensive D-Max around. That’s still the Blade, with a 3.0-litre engine and 4x4 only, but it’s now $80,900.

Back to the 2.2s, and the SX grade comes with the basics. Cloth upholstery, polyurethane steering wheel and gear selector, vinyl flooring and even halogen lights.

There’s basic air-conditioning, but it does have a HEPA filter, and rear vents for crew-cab models, plus there’s wireless Apple CarPlay and Android Auto, auto wipers, and USB-C power ports as well as a USB-A port.

The central multimedia touchscreen is 8.0 inches, but the driver display is a little 4.2-inch unit between physical dials.

Stepping up to the LSM X-Rider brings with it auto-levelling LED headlights and LED daytime running lights, black styling trim, nicer cloth trim upholstery and gloss black 17-inch alloy wheels.

The rest of the D-Max line-up is 3.0-litre-only, and remains as it was before.

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 new 2.2-litre turbo-diesel four-cylinder comes with 120kW and 400Nm, that’s 10kW and 50Nm more than before. Isuzu also says there’s 60 per cent more torque ready from near-idle at 1000rpm.

An eight-speed auto replaces the six-speed, but the brand has also culled the manual options that remained in the line-up.

As ever, that sends power and torque to a part-time 4WD system capable of 2H, 4H and 4L with a rear diff-lock.

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.

The biggest advantage for the new drivetrain from Isuzu’s perspective is that it’s more fuel efficient.

The old engine’s 6.9 litres per 100km become 6.6L/100km in the new engine, in part thanks to a new stop-start system. That system is also now on the 3.0-litre engine, where 8.0L per 100km drops to 7.1L.

With its 76L diesel tank capacity, the D-Max should theoretically be able to travel more than 1000km on a single fill, although that comes down to a lot of variables - that 6.6L figure was achieved in almost lab-like conditions.

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.

Let’s start with the most important part of the updated D-Max. The new 2.2L is smooth. 

It feels so much more refined physically, but it's also quieter. Paired with the new eight speed, it makes the D-Max a much more likeable ute than it was with the rattly 1.9L.

At the launch, Isuzu had a bunch of MU-Xs to drive (keep an eye on a review coming soon), and the new drivetrain actually suits that big family SUV down to a tee.

The power and efficiency changes are second to how much it changes the characteristics of the thing.

If anything, the D-Max sits in a slightly higher gear than necessary, probably to try and eke as much out of the diesel dual-cab as possible in terms of fuel efficiency, but put your foot down and a more appropriate gear is close-by, and without much fuss.

There's also a relatively good stop-start system. It's not seamless but it's better than some. You take your foot off the brake and the engine rattles back to life, rather than waiting for you to put your foot back down.

The rest of the D-Max’s behaviour is pretty standard ute stuff, as it was before.

The steering is on the light side, but accurate enough even though it has a slightly doughy spot dead-straight. It’s not anything you wouldn’t expect from a ute.

Similarly, the brakes are a bit spongy but predictable, and once you’re used to where the ‘bite’ point is it’s easy to live with.

The suspension is a bit busy, but easy to keep on top of and doesn’t jostle you around. 

Isuzu has done well to include pretty much the full range of safety features across all its variants, with the SX only missing out on rear parking sensors - it still has a camera though, obviously.

Key features like rear cross-traffic alert with braking and adaptive cruise control are standard, plus the D-Max achieved a five star crash safety rating from ANCAP, even though that was under slightly easier testing back in 2020.

The biggest (but only) gripe on-test with the D-Max’s safety gear was its lane-keep during adaptive cruise. There seemed to be a need for the ute to sit close to either the centre line or shoulder during cornering, which led to some discomfort on fast country roads.

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.

Isuzu’s six-year/150,000km warranty covers the D-Max, which could do without the limited distance, especially for a workhorse.

There’s also five years of flat-rate servicing every 12 months or 15,000km, costing $469 each time.

That’s gone up about $20 per visit since the update, with total cost over the five years at $2345.

There are 164 Isuzu dealers across the country, so finding somewhere to service shouldn’t be a challenge.
