Ineos Grenadier vs Isuzu D-Max

What's the difference?

The Ineos Grenadier Quartermaster is best regarded as a charming old-school oddity in an increasingly cookie-cutter dual-cab ute market.

In the same vein as the Suzuki Jimny, Jeep Gladiator, and Toyota LandCruiser 70 Series, this ute is for those of us who really like driving to be a fully immersive experience and don’t mind a few sacrifices and some discomfort along the way.

Good on Ineos for giving it a crack.

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.

The Quartermaster is 5400mm long (with a 3227mm wheelbase), 1943mm wide, and 2019mm high. It has a listed kerb weight of 2718kg and a 14.5m turning circle.

I’m always reluctant to talk about any vehicle’s design but it’s easy with something like this ute.

The Quartermaster has a distinctive look. It’s blocky, hard lines everywhere, and it’s straight up and down, old school.

Substantial side steps/runners, exterior utility belt (a integrated feature by which you can attach accessories, tools, or cargo to the Quartermaster’s exterior), and BFGoodrich All-Terrain KO2 all-terrain tyres on 17-inch alloy wheels add to this ute’s presence.

It certainly catches everyone's attention, for better or worse because some people like it, some people don't. I happen to be part of the mob who actually like the look of the Quartermaster and its sibling, the Grenadier station wagon, and the design pretty much works overall.

Extras like the black contrast roof, safari windows and raised air intake further set this Quartermaster apart from most other modern dual-cab utes on our roads.

The interior is somewhat spartan but well laid-out and comfortable. It has lots of controls and quirky styling to keep everyone inside occupied and while, at first, it’s all a confusion of buttons, knobs and dials, it soon takes on a more familiar feel as you become accustomed to everything.

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’.

In terms of practicality, it's pretty good news inside the Quartermaster cabin when you first climb in. As mentioned, there is a confusion of dials, buttons, knobs, everything in front of and above you. But give yourself some time to locate controls and understand how to best use them, and you'll be absolutely fine.

As alluded to in Design, the cabin looks really good but it also functions quite well as a work or travel space. Once you are underway and you have a firm understanding of everything, it all feels comfortably familiar.

There are hard plastic surfaces in the cabin, leather accents, as well as plenty of quirky styling cues around the cabin, including port and starboard markings, aircraft cockpit-style controls and more, and you'll have fun discovering those.

The floor has drain plugs and the buttons and switches have an IP54K rating (protected from limited dust ingress and water spray from any direction) with the idea being that, worst comes to the worst, you can always hose out the interior if it gets really dirty.

The Recaro seats, front and rear, are very comfortable. There's not a whole lot of room in the rear seat. You don't get much leg and knee room, especially if you are tall, but the seats are raised for optimised visibility to the front and otherwise, with big glass everywhere and safari windows, it’s an airy and useable space. 

The auxiliary battery is under the rear seat.

All in all, it's a functional and comfortable interior.

Anyway to the business end. The tub is 1564mm long, 1619mm wide (1137mm between the wheel arches) and 485mm deep. It has a sturdy tub liner, four-tie-down points, a load-space light, power socket.

The full-sized spare was located in the rear left-hand corner of the tub and while that’s not ideal and certainly doesn’t optimise the load space, it can be shifted elsewhere – on the roof perhaps – and it’s not as much of an eye-sore as the spare in the GWM Cannon Alpha PHEV tub.

The spare tyre also has the optional lockable storage box ($490) attached to it, so you can throw a bit of gear inside there and keep it secure during your travels.

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 Ineos Grenadier Quartermaster is available with either a 3.0-litre inline-six turbo-petrol engine (producing 210kW at 4750rpm and 450Nm at 1750-4000rpm) or a 3.0-litre six-cylinder turbo-diesel engine – producing 183kW at 3250-4200rpm and 550Nm at 1250rpm-3000rpm.

Both engines are from BMW. Our test vehicle has the diesel.

This Quartermaster has an eight-speed ZF automatic transmission and a dual transfer case (high- and low-range 4WD), as well as a front, centre and rear diff lock.

This is a nicely refined engine-and-auto combination, offering up a decent punch of power and torque across a broad rev range when it’s needed.

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.

Official fuel consumption is 10.5L/100km on a combined cycle.

On this test, I recorded 12.3L/100km.

The Quartermaster has a 90-litre fuel tank so, going by that fuel figure, you could reasonably expect a driving range of about 730km from a full tank. However, long-range fuel tanks are available, so there’s always that option.

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.

First things first, just to put your mind at ease – the Quartermaster is not absolutely terrible to drive on road, in fact it’s actually quite nice: planted, comfortable (on coil-spring suspension), and refined (for a ute).

It’s no surprise that a long four-wheel-drive ute does really well on-road, even if it is a heavy solid axle vehicle and not particularly dynamic.

What's also not surprising – because on paper this is an off-road beast – is that the Quartermaster is very capable off-road.

It has three diff locks (front, centre and rear), off-road mode, hill descent control and more, so it's an effective mix of traditional mechanicals and driver-assist tech. That's the dual range transfer case, but it also has electronic traction control. The 3.0-litre turbo-diesel engine and the eight-speed automatic transmission work well in on-road situations and it's also a clever smooth combination in off-road scenarios.

So there's plenty to like about this ute when it comes to 4WDing.

Be aware though: this is a big, heavy vehicle with a long wheelbase, so it takes considered driving to steer around – it has a big turning circle at 14.5 metres – but that's not to say those dimensions and those characteristics ruin it off-road because they don't. The Quartermaster simply requires a bit more thought when you're driving it.

If you haven't spent a lot of time or any time in vehicles like this, such as the Toyota LandCruiser 70 series or of that sort of ilk – big long old-school four wheel drive utes – then you may have a bit of an issue with the steering. It is slow, and there is a lot of play to it, especially off-centre. It does feel floaty and it takes a lot of effort and constant micro-corrections when you're driving to keep it on track and to keep it going where you want to. Put it this way: it’s not self-centred so you have to work at getting it back on track once you’ve taken on a turn.

But I like that, because four-wheel driving should be an entirely immersive experience, you should be always directly involved in the process and in this ute you are.

There’s plenty of power and torque across a nice rev range, with plenty of torque down low, which is crucial when off-roading.

And while the stretched wheelbase makes the underbody vulnerable to knocks and scrapes, especially over more severe 4WD-only terrain, the Quartermaster actually manages quite well.

Its approach, ramp breakover and departure angles – 36.2, 26.2 and 22.6 – are reasonable for something of this size and with 264mm of ground clearance and 800mm of wading depth, this ute has the measurements to cope with most off-road challenges you could throw dirt at.

Another thing I like about the Quartermaster is the fact it retains an old stubby stick, that’s working off the dual-range transfer case, to put the vehicle into low range and that's a welcome touch and a practical nod to the past, rather than a button or a dial.

As mentioned earlier, it has live axles, so there’s flex through the front and rear, although it'd be even better with a swaybar disconnect system onboard (as in the Jeep Gladiator).

This Trialmaster gets the BFG KO2s and where the standard tyres on a contemporary ute may not be up to scratch in off-roading terms, the KO2s work really well. It’s impressive what a difference decent all-terrains make, and if you want to get into the sloppy stuff, then you might consider getting some mud-terrain tyres.

So the Quartermaster is a very capable four-wheel-drive ute and there's a lot to like about it, but the issue with a vehicle like this is that people may come into it not understanding exactly how it rides, how it drives and how involved you actually have to be and the fact that there are lots of compromises, indeed some sacrifices.

You're not getting as much driver-assist technology as you get in other utes, and it doesn't drive as precisely or perhaps as comfortably as some other utes – but that's missing the point.

The Quartermaster is about that all-encompassing off-roading experience. And if you get in one of these things, you have to be all-in, ready for the bumps and the discomfort and the effort it requires but all of those things add to the appeal of this ute, rather than detract from it.

And that's a major point of difference with this ute over others in the market: in being faithful to the spirit of old-school 4WDing, Ineos has been willing to forgo those things which people have come to expect and as a result it may only draw the faithful, the committed, who are all-in for off-road adventure.

Where the Quartermaster falls short, however, is in terms of practical use because its payload is 832kg in the diesel version and that’s disappointing, especially when a 2.8-litre LC70 GXL dual-cab can cope with 1325kg.

It is rated to tow 750kg unbraked, and 3500kg braked and with a kerb weight of 2718kg it has a GVM of 3550kg and a GCM of 7000kg.

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.

The Ineos Grenadier Quartermaster is covered by a five-year/unlimited km warranty, not the best in terms of years of coverage, but on par with the likes of the LC70.

A 12-year anti-perforation warranty – covering body sheet metal panels and chassis frame against inside-to-outside corrosion caused by defective materials or workmanship – applies to this ute.

No capped-price servicing is available and service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest, and total cost for the five years is $4626 for the diesel and $4896 for the petrol.

At the time of writing, Ineos has 25 sales and service centres, two sales-only centres and 55 service-only centres spread throughout Australia with a focus on regional and rural areas.

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.
