Lexus Rx450H+ vs Ineos Grenadier

What's the difference?

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

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 RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

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 RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

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.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

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 plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

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 RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

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.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.

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.
