Ineos Grenadier vs Rivian R1S

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.

While there are some obvious signs that the R1S is Rivian’s first mass-market vehicle, the good news for the company is that its problems are not impossible to overcome. The suspension needs retuning to improve the ride quality and the multimedia system’s software needs upgrading. But even with those issues the R1S left a positive impression.

This is a very stylish SUV with great space and excellent performance, that also happens to be electric, rather than relying on being electric as its primary selling point.

Rivian has put more effort into the design and finishes than many of its EV rivals and the result is a vehicle that can genuinely compete with the established premium players with more credibility.

The only catch is there’s no clear timeframe for when, or even if, this generation of R1S will make it to Australia. The brand has repeatedly spoken of its hopes of entering the market here without locking anything in, but given the current state of the EV sales it may pay off to wait until the conditions are right for a new, premium player to try its luck here.

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.

Design is another area where Rivian has carved out a unique position for itself. Whereas other brands, including Tesla, have focused on simplicity and aerodynamic efficiency, Rivian has given the R1T a unique style that looks interesting, different and most definitely not plain.

The oval daytime running lights make every R1S and R1T stand out from a mile away, even on LA’s busy freeways. The overall design is high quality and manages to strike a good balance between aesthetics, aerodynamics and practicality - even if it doesn’t suit everyone’s personal taste.

The cabin is worth highlighting in particular, because rather than go for the ‘minimalist’ look that so many brands are going for these days, with as little switchgear and different trims as possible to keep costs down, Rivian has opted for something more complex and, frankly, more impressive.

There’s a level of craftsmanship, a great mixture of premium materials (including some striking light wood options) that make the R1S feel like a stylish and relaxed environment inside the cabin. Our particular example had a great mixture of colours, textures and patterns that really elevated the cabin experience.

The technology is also nicely integrated into the design, rather than being the focal point, like so many other modern electric vehicles. It still offers the same level of technology - a pair of screens - but doesn’t rely on them to carry the design of the interior.

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 R1S comes standard as a seven-seat SUV, split across three rows (two in the first row, three in the second row and two in the third row). Space across the three rows is fairly typical for an SUV of this size, which is to say generous up front, good in the second row and a little bit tight in the back.

What is good though, is the length of the cabin allows for quite a spacious boot even with the third row in use, which is definitely not something all seven-seat SUVs can claim. Using a direct conversion from Rivian’s specifications that list cargo capacity in cubic feet, the R1S has a claimed 498 litres with the third row in use and up to 1331L with the third row folded down. There’s also 314L under the bonnet and another 144L underneath the boot floor (although that comes at the expense of a spare tyre).

As mentioned in design, Rivian has nicely integrated the technology into the cabin, with the 12.3-inch digital driver display and 15.6-inch central multimedia touchscreen feeling like a natural part of the car rather than a centrepiece. Rivian has also managed to incorporate eight USB-C charging ports spread around the cabin to keep everyone’s devices charged up.

However, while the technology is nice from an aesthetic design perspective, the same cannot be said about its useability. Like Tesla, Rivian has opted to go it alone with its multimedia system and has developed its own Google-based software that is not compatible with either Android Auto or Apple CarPlay. That would be acceptable, although still disappointing, if the system worked as well as Tesla’s, however the Rivian system is very slow. It repeatedly took several seconds to load between the various functions, which may not sound like long, but when you’re trying to get back to the navigation so you don’t miss your freeway exit a few seconds can make a big difference.

But, honestly, in this day-and-age, systems like this should work quickly and seamlessly, so it’s an area Rivian needs to improve.

On a positive note, Rivian does have some cool accessories for the R1S including what it calls a ‘Camp Speaker’ which is a US$400 option that it integrates into the sound system but is also removable, so you can pull it out of the centre console and listen to your music if you’re around the campfire or having a picnic.

When we drove the R1T in 2023 Rivian was still in the ramp up stage of production and was limited with what it could offer customers. Fast forward to 2025 and the brand now has both the R1T and R1S available with dual or tri motor powertrains, with a quad-motor powertrain expected by the end of the year.

The R1S Dual Standard begins the range at US$75,900 (approx. A$118,000), the R1S Dual steps it up to US$83,900 (A$130k) and the R1S Tri-motor completes the current line-up at US$105,900 (A$165k). While those prices are definitely in the premium end of the market the R1S is actually cheaper than the Tesla Model X, which is still on sale in the US market, and starts at US$86,630 (A$135k) and stretches to US$101,630 (A$158k).

For more context, the Audi Q8 e-tron starts at US$74,800, the BMW iX from US$87,250 and the Mercedes-Benz EQE from US$77,900.

Standard equipment across the range includes the 12.3-inch digital instrument display, 15.6-inch multimedia touchscreen, dual-zone climate control, heated and ventilated front seats, heated steering wheel, eight-way power adjustable driver and passenger seat and panoramic glass roof, so it certainly has premium levels of equipment.

We drove the range-topping RS1 Tri-motor which, aside from an extra motor, gets standard 22-inch alloy wheels, a dynamic glass roof, a soft-touch suede textile headliner as well as unique colour and trim options.

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.

As mentioned earlier, there are currently three versions of the R1S available, each with a different powertrain. 

The Dual Standard AWD has, unsurprisingly, dual motors (one at the front and one at the rear) which make a combined 397kW/827Nm. That’s enough for it to launch 0-60mph (0-96km/h) in just 4.5 seconds. The R1S Dual AWD has the same power, torque and acceleration figures, however it gets Rivian’s Large battery, which we’ll detail below.

The Tri-Motor AWD obviously has three motors, one on the front axle and two on the rear, which naturally provide more power, 633kW/1495Nm. With so much power and torque the Tri-motor is wickedly fast, taking just 2.9 seconds to launch 0-60mph.

If, for some reason, the Tri-Motor isn’t fast enough for you, Rivian has released the details on the Quad-Motor. It will have two motors on each axle providing a staggering 764kW (that’s 1025-horsepower!) and 1624Nm, enough to rocket it from 0-60mph in just 2.6 seconds and across the quarter mile in 10.5 seconds.

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.

Rivian offers three different battery types across the three variants, each with a different driving range. The R1S with the Standard battery (92.5kWh) has a claimed 434km driving range, the R1S Dual with Large battery (109.4kWh) extends that to 530km, while the Tri-Motor comes standard with the Max battery (141.5kWh) that has an impressive 597km of range.

It is worth noting, though, that those range claims are based on US EPA estimates, rather than either the WLTP or NEDC methods usually used.

Charging times vary depending on the type of charger used, in the US Tesla has given access to its network to other EV brands and the Rivian is available with a plug adaptor to use a Tesla charger. The R1S is capable of charging up to 220kW, which means it takes approximately 40 minutes to take the battery from 10 to 80 per cent. 

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 R1S and R1T are Rivian’s first mass-produced cars, and it shows. It’s not all bad news by any stretch, but there are some major issues the brand will need to address in the future if it wants to succeed globally (or even just in the US). 

The biggest issue is the ride, which just doesn’t feel as well resolved as the more established brands that have been designing, developing and building cars for decades. The R1S isn’t bad to drive by any stretch, but the ride is too firm at times and it also lacks control and feels too soft at others. 

All R1S grades come standard with Air Suspension that has multiple levels of firmness and can adjust the ride height. However, in the ‘normal’ setting the ride feels too busy, with the heavy (3096kg) SUV skittering over the imperfections in the road rather than absorbing them. The problem is, if you adjust the suspension to the softer setting it lacks control and has a tendency to bounce over bigger bumps and take a few seconds to settle. This was particularly noticeable on LA’s concrete freeways, but it would be an issue on any road with undulations or joints.

But while the ride needs improvement, the R1S has strengths in other areas - namely performance. The Tri-motor AWD we sampled had immense punch from its three motors and it certainly felt like 633kW and 1495Nm was on tap. We didn’t test its acceleration claim officially, but any take-off could be made into a rapid one with just a squeeze of the accelerator pedal. 

The R1S is also capable of towing up to 3500kg, so it’s a strong and capable SUV too, rather than just a speedy EV.

Another strength is the regenerative braking system. There are multiple settings but we found the lowest regen was the best option, as it still provides powerful regen but is more progressive than the more powerful modes.

The R1S comes loaded with safety equipment across the range, including eight airbags, adaptive cruise control, autonomous emergency braking, blind spot monitoring, forward collision warning, lane departure warning, lane keeping assist and rear cross-traffic alert.

It also comes with what’s called the ‘Rivian Autonomy Platform’ that includes 11 cameras and 12 ultrasonic sensors for mild-autonomous functionality in specific circumstances, such as freeway driving or on well-marked 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.

Rivian offers a four-year/80,000km warranty for the R1S vehicle as a whole, as well as a separate battery pack and drivetrain specifically. The Standard battery is covered for eight years/190,000km while the Large and Max batteries are covered for eight years/240,000km.

As for servicing, Rivian uses an app-based system, which allows owners to schedule a service at any time via the app and then either have a Rivian technician come to your home for a small service or drop it off at a service centre if it’s a bigger job. The app is also connected to the car, so if the car’s own diagnostic system recognises a problem, it can prompt you to book a service proactively.
