Lexus Gx550 vs Ineos Grenadier

What's the difference?

The new Lexus GX 550 Sports Luxury looks fantastic and has enough mod cons to satisfy a family but it’s not as luxurious as you’d expect from a premium brand and the fuel economy and driving range will turn off some. But if you’re still interested, there’s a lot here that will make you happy and it’s one of the smoothest 4WDs I’ve driven.

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 GX 550 looks massive and while it shares the same platform as the Toyota LandCruiser 300 series, it doesn't share all of its bulk. They both stand at 1980mm wide but differ on length (5015mm vs 4980mm) and height (1670mm vs 1950mm), respectively.

The new design is fabulously rugged but each body panel looks meticulously crafted and is just the right size. This just means the proportions look right and your eye sort of glides over the big body rather than stopping on any one feature.

But having said that, there are a lot of nice features to focus on, like the long LED headlights and rear strip light, auto-folding side steps, 22-inch alloy wheels and sharply styled rectangular side mirrors.

The tailgate window can also be opened if you need to pop something into the boot but don't want, or have the space, to open the tailgate itself.

The styling takes a minor nose dive once you hit the cabin, though, because it doesn't look as sumptuous as you'd expect in a premium SUV.

I love the utilitarian and military vibe of the vertical dashboard, chunky air vents and relatively small windscreen. It looks great but some trims are plasticky and the touchpoints, while soft, are not Lexus-plush.

However, the technology looks gorgeous with an integrated 14-inch multimedia display and a 12.3-inch digital instrument cluster. The fixed sunroof with its two settings (clear or opaque) is also a lovely feature.

But on a whole, the GX 550's European rivals outclass it with their flashier cabins.

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 cabin of the new GX 550 is fairly practical with plenty of head- and legroom in each row (yep, even the third!). When you first hop in, it can feel a big snug on elbow-room but this feeling quickly dissipates.

Despite a 215mm ground clearance, access is pretty good for the front and middle rows due to the wide door apertures and side-steps. Third row access is a bit awkward for an adult but my eight-year old loved scampering back there this week.

The electric front seats are comfortable with their extra functions and I like the way the massage feature extends to the seat cushion as it limits fatigue on longer journeys. However, you sit on top of them rather sink into them which makes it feel a little trucky at times.

The wide middle row has a bench seat that will be comfortable for kids but an adult might get a sore behind on a long trip. The transmission tunnel also compromises foot room for adults but the seat is wide enough to make use of all three top-tether anchor points (there are ISOFIX mounts too).

It was a little bit of an effort to lift my big booster seat into the back because the GX 550 sits so tall but otherwise, there's plenty of room around a child seat for them not to feel like a sardine.

Individual storage is made up of a glove box that fits an owner's manual, a small shelf in the dashboard and a middle console that doubles as a cool box (mini fridge) and can fit up to four cans or bottles in it.

Each row gets four drinkholders and two USB-C ports but the front also enjoys a 12-volt socket and wireless charging pad. There's a 220V domestic plug port in the boot for larger appliances, too.

It's sometimes awkward to use the wireless charging pad because it's easy for your phone to slide around on it and it quite often disengaged from charging.

My son enjoyed all of the other amenities in the middle row, like the reading lights, climate control, two USB-C ports and retractable sunblinds and I applaud carmakers when they position rear directional air vents in the pillars and/or roof. It just makes it so much easier to cool down sweaty kids!

The 14-inch multimedia display has clear graphics and a responsive touchscreen. The layout is easy enough to get used to after spending some time with it and the sat nav is simple to use.

I like that the sat nav directions can be pulled into the 12.3-inch digital instrument cluster and head-up display.

There is a Lexus connected services app, which you get a three-year subscription to. It's easy to connect to the wireless Apple CarPlay and there is also wireless Android Auto.

The system also has Bluetooth and digital radio, which is a delight to use through the 21-speaker Mark Levinson sound system.

The cabin is rounded out by the well-shaped boot which has a massive 1063L of capacity when the third-row is folded. That's been more than enough for my family's needs this week and my German Shepherd was pretty comfy back there, too. The powered tailgate has a kick-function and there is a full-size spare wheel underneath the car.

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.

This ute is available in three different spec levels: the base-spec Quartermaster, the Fieldmaster and, this, the Trialmaster.

It’s available with one of two BMW-sourced engines: 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.

I tested the diesel-powered variant.

The Trialmaster has a starting price of $118,000 before on-road costs, but our test vehicle has $15,386 worth of accessories onboard pushing its as-tested price up to $133,386.

Standard features onboard the Trialmaster include a 12.3-inch touchscreen multimedia system (with wireless Apple CarPlay and Android Auto), permanent four-wheel drive, centre diff lock, and front and rear skid plates.

Other noteworthy features inside this test vehicle include leather trim (black, $3405), heated front seats ($715), Nappa Leather Driver’s Pack, as well as auxiliary battery, auxiliary charge points, high load auxiliary switch panel and electrical preparation, 400W Inverter, and load bay utility rails.

Other features on the outside of this Trialmaster include a contrast roof – Inky Black ($2460), front and rear diff locks (standard on the Trialmaster), raised air intake, privacy glass ($770), safari windows ($2720), 17.0-inch alloy wheels ($1165), Class III 1-7/8” NAS tow hitch and electrics, a load bay liner, and a spare wheel lockable storage box ($490).

Exterior paint colours include the standard Britannia Blue (solid) or you can choose from Scottish White (solid, $1155), Magic Mushroom (solid, $1155), Eldoret Blue (solid, $1155), Sela Green (solid, $1155), Inky Black (solid, $1155), Devil Red (solid, $1315), Shale Blue (metallic, $1520), Queen's Red (metallic, $1520), Donny Grey (metallic, $1520), or Sterling Silver (metallic, $1520).

But what you want to know is how is it off-road and is it a replacement for the 70 Series, so let’s keep punching on through this yarn.

All GX 550 grades share the same 3.5L V6 twin turbo-petrol engine which produces up to 260kW of power and 650Nm of torque.

This 4WD has high- and low-gearing, as well as a bunch of driving modes to suit most occasions, like 'Eco', 'Comfort', 'Sport' and 'Sport+'.

The 10-speed automatic transmission shifts through its gears smoothly and it always feels like it's engaged in the right gear. Which isn't always the case for a big SUV!

The Sports Luxury is fitted with a towing hitch and cover but unlike the base Sports grade which has a 3.5-tonne braked towing capacity, this model only has a 3130kg capacity which might not appeal to families with big toys to tow. 

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.

I didn’t have high hopes for fuel economy because the official combined (urban/extra-urban cycle figure is a hefty 12.3L/100km but after mostly open-road driving, with some urban stuff mixed in, my real-world average came in at 11.8L.100km! This figure is based on my actual km travelled (358km) and litres of fuel used (42.41L).

While I’m surprised by the fuel usage result, I wouldn’t say this car has good fuel economy compared to its diesel-powered counterparts but it’s not terrible!

The GX 550 has a relatively small fuel tank compared to its Toyota cousins at 80L and based on the combined fuel cycle, you’ll get a theoretical driving range of up to 650km.

Not all that great. Not for a big family mover and not if you’re typically driving in the city, where fuel usage will be a lot higher.

The GX 550 only accepts premium unleaded petrol (95 RON), too.

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.

Oh my goodness the Sports Luxury is a masterclass on 4WD refinement! You never feel the bulk or weight of this massive SUV when you’re driving it. The power delivery is effortless and there’s lots of grunt available when you hit hills.

The handling is also very good with responsive steering and enough road feedback as a driver to make you feel comfortable with what the car is doing. There is some roll in corners but it can tackle more corners at speed than I thought it would. 

The high driving position makes me feel like I can see a long way ahead yet while visibility is mostly good, it can be compromised when you have the side window shades and the third row headrests up. Which is why I love the digital rear view mirror.

Overall, ride comfort is good with forgiving suspension and low cabin noise, even at higher speeds. It’s pretty easy to chat with all rows and there’s not a lot of engine noise which adds to the refinement. I do like hearing a V6 rumble but that’s just a personal preference. 

I was a little worried about hitting my local Westfield car park but this is a nimble SUV to manoeuvre and parking it is a breeze with the 360-degree camera system and parking sensors. 

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.

The Ineos Grenadier Quartermaster does not have an ANCAP safety rating because it has not been tested.

As standard, it has six airbags, electronic stability and traction control, rear park assist, a tyre-pressure monitoring system, and trailer-stability assist.

It does not have auto emergency braking (AEB), adaptive cruise control, blind-spot monitoring, lane-keep assist, or traffic sign recognition.

The Quartermaster does have a rear-view camera, but the screen is quite small.

Front and rear parking sensors are standard on the Fieldmaster and Trialmaster, but optional on the base-spec Quartermaster.

Lexus offers the GX 550 with a five-year/unlimited km warranty, which is fairly standard compared to its Euro rivals.

You get five years capped-priced servicing which costs $5950 but the servicing schedule is a bit of a bear at every six months or 10,000km, whichever occurs first.

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.
