Ineos Grenadier Quartermaster

DOUBLE CAB PICKUP3,227 MM WHEELBASEBMW B58 / B57 3.0 I6COILS ALL ROUND

“A Grenadier with a foot of extra frame and a bed that takes a Euro pallet, as long as you lift the spare out first. It's a seriously capable off-roader that happens to have a tailgate, and in America it carries a 25% chicken tax on top.”

PART 01

Overview

Where it came from, why it matters, and how it changed year to year.

The story

Most pickups start as trucks and get dressed up as lifestyle accessories. The Quartermaster went the other way. Ineos took the Grenadier Station Wagon, stretched its ladder frame by 305 mm, cut the roof off behind the second row and fitted a bed sized for a 1,200 × 800 mm Euro pallet. It still has coil springs at all four corners, Carraro beam axles and a BMW straight-six, so it rides and crawls like an expedition wagon with an open load bay. AutoDaily put it neatly: it's "more of a 4×4 with an open load area than what we would call a pick-up."

FROM GOODWOOD TO HAMBACH

The Quartermaster made its public debut at the Goodwood Festival of Speed in July 2023. Series production began in November 2023 on the same Hambach, France, line that builds the wagon, in the former Smart factory Ineos bought from Mercedes. European deliveries were due from December 2023, with Asia Pacific, the Middle East and Sub-Saharan Africa next. A bare cab-chassis for tray bodies was added in Australia and New Zealand.

Australia, where Ineos partnered with tray maker Norweld, was a key market. There the Quartermaster goes head to head with the 70 Series LandCruiser ute, which still has a leaf-sprung rear. Caravan World drove both and found the Ineos more compliant over small bumps and "blasts the 79 Series out of the water" off-road. The Toyota keeps the edge on payload, price and parts availability.

WHAT THE EXTRA FOOT BUYS (AND COSTS)

The bed is 1,564 mm long and 1,619 mm wide, with 1,337 mm between the wheel arches, four lashing eyes and a 400 W power outlet. The tailgate takes 225 kg (about 496 lb) when it's down. Payload depends on market and engine: Ineos quotes up to 907 kg for an Australian petrol truck and 832 kg for the diesel, and about 1,675 lb at US launch. Towing stays at 3,500 kg (about 7,700 lb), the same as the wagon. Petrol output is unchanged at 282 hp; the diesel makes 550 Nm.

The extra length costs some geometry. Approach angle is a strong 36.2°, but breakover falls from the wagon's 28.2° to 26.2° and departure from 36.1° to 22.6°. That's why the spare wheel lives upright in the bed rather than under it, where it would hang down and cut the departure angle further. The catch is that you have to lift the spare out before a pallet will go in. Turning circle grows to about 14.5 m, roughly a metre more than the wagon, and Top Gear called that figure "genuinely appalling."

THE AMERICAN PROBLEM

Ineos opened US orders in April 2024 at $86,900 for the base Quartermaster and $94,900 for the Trialmaster and Fieldmaster, all before destination. That was $15,400 more than the Station Wagon, and most of the difference was the 25% chicken tax on imported light trucks. The September 2024 production stoppage, caused by a parts shortage after supplier Recaro Automotive went insolvent, pushed US deliveries back, and the first cargo ship of Quartermasters reached America in March 2025. A month later, new US tariffs took the total import duty on the truck to 50%.

Ineos said it would absorb most of the extra tariff, but the US starting price still rose 11%, from $85,500 to $94,500 including shipping, according to Automotive News. Ineos told the paper the Quartermaster could reach up to 20% of its US volume and pitched it against the Rivian R1T and F-150 Raptor rather than a Silverado. Expedition Portal's long-term test truck towed a 5,000-plus-pound Xplore overland trailer and drew this verdict: "Expect it to drive like the HD truck it is and not a car, and it won't disappoint."

THE 2026 FIX AND THE BUILD SCENE

For 2026 the Quartermaster got the same fix as the wagon: a variable-ratio steering box that's firmer and more precise near straight-ahead, steering stops that cut the turning circle by about 5%, better climate-control components and a faster way to silence the Intelligent Speed Assist chime. A Black Edition joined the range, and US 2026 price lists show no base Quartermaster, starting instead at the Fieldmaster and Trialmaster. The off-road hardware didn't change.

The aftermarket has been quicker than the factory. Norweld builds trays and canopies, Dirtbox Overland sells a $11,499 canopy camper made for the bed, and Leitner Designs makes a full-length roof rack that bolts to the roll cage rather than the gutters. Owners on the INEOS Forum fit Dirtbox caps, adjustable shocks and spare-wheel relocations, and Expedition Portal has filmed a Quartermaster on Letech portal axles. It's the closest thing on sale to a new 130-inch Defender pickup, and owners are building it that way.

SIDEBAR · THE KAIJU

Ineos Builds the Ute Australians Would Build

In December 2024 Ineos Australia revealed the Kaiju, a one-off Quartermaster built with local aftermarket partners to show how far the platform can go. It started as a Trialmaster with three lockers, a raised air intake, an auxiliary battery and factory bull bar, sliders and checker plates.

Norweld fitted an aluminium tray with a 1,200 mm trundle drawer, a 40-litre water tank and a Compact Deluxe Lite canopy holding a 130-litre fridge. REDARC supplied a 2,000 W inverter and 150 Ah lithium battery, Brown Davis a 168-litre long-range fuel tank, and JMACX remote-reservoir shocks replaced the factory dampers. It ran 315/70R17 mud-terrains. Ordered through Ineos retailers, selected parts from official accessory partners come with extended Ineos warranty.

Specs & capability

How it’s built, what it can do, and what fits under it.

How it’s built

Under the bed, the Quartermaster is a stretched Grenadier. The box-section ladder frame is 305 mm longer, and everything bolted to it carries over: Carraro beam axles on five-link coil suspension with progressive-rate Eibach springs, permanent 4WD through a Tremec two-speed transfer case, and BMW six-cylinder engines with a ZF eight-speed automatic. The rear body is the wagon's up to the back doors, then it becomes a steel bed with a pallet-width floor.

Buying one

What to pay, what to check, and how to tell a good one from a clone.

What they cost

Too new and too rare for a meaningful auction record; US prices are set by the chicken tax and 2025 tariffs, not by depreciation yet.

New 2026 Fieldmaster or Trialmaster (MSRP)$86,395
New 2026 Black Edition (MSRP)$90,390
New 2026 Trialmaster X Edition (MSRP)$93,390

MSRPs as reported in October 2026, before destination. The only Bring a Trailer Quartermaster so far, a 2025 Trialmaster Edition, sold for $76,000 on July 31, 2025. Prices move; checked October 2026. See live listings below.

What to check before you buy

  1. 01
    Run the VIN at NHTSARecalls 23V828 (auxiliary switch relay wiring), 23V903 (steering ball-joint nuts) and 25V147 (door buttons) are filed against 2023–2024 Grenadiers. As of October 2026, NHTSA's recall database lists none for 2025–2026 models. Check every truck by VIN anyway, and get proof that any open campaign was closed.
  2. 02
    Do the payload math before you buy a camperPayload is modest for a pickup: about 1,675 lb at US launch, and 832–907 kg in Australia depending on engine. A canopy, fridge, water, a second battery and a winch use that up quickly. Expedition Portal says even its Trialmaster test truck (winch, dual batteries, bed rack) is rated at about 1,400 lb. In Australia, Caravan World quotes a GVM upgrade to roughly 3,900–4,000 kg for about A$5,800 plus fitting.
  3. 03
    Know where the spare will liveFrom the factory the spare stands in the bed, sticks up above the bed sides and has to come out before a pallet will fit. It also gets in the way of flat tonneau covers. Ask whether the spare has been relocated (owners have moved it under the deck or under the rear axle) and check that the new mount is solid.
  4. 04
    Drive it empty and on the highwaySeveral INEOS Forum owners describe an unladen Quartermaster as 'jittery' over bumps in a way the wagon isn't, though it settles once a canopy and gear go in. Pre-2026 trucks also have the slow, non-self-centring steering box and a 14.5 m turning circle. MY2026 trucks get the variable-ratio box and a turning circle about 5% tighter.
  5. 05
    Wellside or cab-chassis?Outside the US you can buy a cab-chassis and fit a tray. Ineos and Norweld offered early Australian cab-chassis buyers a A$7,000 tray contribution, with conditions. Caravan World lists Norweld trays from A$18,990 and canopies from A$19,205, so a tray build costs a lot more than the tub truck, but it gives you a flat, wider deck.
  6. 06
    Confirm the lockers and Trialmaster kitThe centre diff lock is standard on every truck. Front and rear lockers come on the Trialmaster or with the Rough Pack. The locker switches are in the overhead panel, and the centre lock is on the transfer lever. Trialmaster trucks also get a raised air intake and all-terrain tires.
  7. 07
    Check the bed for tie-down track and holesSome dealers fit L-track to the bed and sides. One forum owner noted that some trucks were built without bed rails, so adding them means drilling and countersinking. Look for neat, sealed holes and no rust starting around the fasteners.
  8. 08
    Ask about parts and the dealerCaravan World scored accessibility of spare parts 7/10. The engine and gearbox come from BMW and ZF, but body, bed and chassis parts come through Ineos's small network. Ask the nearest dealer about lead times, especially if you travel remote.

Spotting the real thing

Quartermasters come as Fieldmaster, Trialmaster, Black and Trialmaster X in the US, and spec matters more than year for off-road use.

Post-purchase baseline

After you buy it

Assume nothing was done early: the factory schedule is long (12 months / 12,000 miles in the US), the full service manual isn't sold to owners, and only dealers can reset the service counter. Baseline every fluid once, keep receipts with OEM-spec fluids to protect the 5-year warranty, and note that much of the drivetrain is shared with BMW (B58/B57 engines, ZF 8-speed), so FCP Euro and other BMW specialists carry many of the consumables. On a Quartermaster that has worked hard (towing, a camper or tray load), treat it as arduous use and shorten every interval.

Asked on every forum

Ineos Grenadier Quartermaster questions, answered

What's the biggest tire I can fit without a lift?

The Quartermaster has the same axles and front suspension as the wagon, and it comes on LT265/70R17 or 255/70R18 (about 32 in.). Wagon owners on the INEOS Forum report 285/70R17 fits without rubbing and 285/75R17 (about 34 in.) fits on stock suspension. DVA Mechanics treats 35s as a 2-inch-lift job. One Quartermaster owner recommends narrow 35s on near-factory offset wheels, such as 255/85R17 or 35×10.5. Because the spare sits in the bed, there's no rear-door clearance problem like on the wagon, but a bigger spare stands taller in the bed. An owner at 7,000 ft stayed at 33s because of power loss on the factory gearing.

How much payload does it have?

It depends on market and engine. Ineos quoted 1,675 lb at US launch. In Australia it quotes 907 kg for the petrol and 832 kg for the diesel, against a 3,550 kg GVM. That's below most one-tonne utes and the 79 Series LandCruiser. Expedition Portal says its Trialmaster test truck, with a winch, dual batteries and a bed rack, has a 1,400 lb payload.

3,500 kg braked (about 7,700 lb), the same as the wagon, with a 7,000 kg GCM and a 350 kg towball limit in Australian spec. With a heavy trailer and a loaded bed you'll reach the GCM and payload limits before the hitch rating.

Will a Euro pallet really fit?

Yes. There's 1,337 mm between the wheel arches, enough for a 1,200 × 800 mm pallet. You have to take the spare wheel out of the bed first.

Where's the spare, and why?

It stands upright in the bed. Mounted underneath, it would cut into a departure angle that's already down to 22.6°. Ineos also offers a roof mount and a 15-litre lockable box that fits in the middle of the spare. Owners have moved it under the deck or under the rear axle.

Can I get the diesel in the US?

No. US trucks have only the BMW B58 3.0 petrol six (282 hp, 332 lb-ft). The B57 diesel (183 kW, 550 Nm) is sold in Europe, Australia, New Zealand and other markets.

Why does it cost so much more than the wagon in the US?

Mostly the 25% chicken tax on imported light trucks. At launch the Quartermaster cost $15,400 more than the Station Wagon. When new tariffs arrived in April 2025, total duty rose to 50%. Ineos said it would absorb most of that, but still raised the price 11%, to $94,500 including shipping.

How does it drive compared with the wagon?

It's much the same, with a longer turning circle: about 14.5 m against 13.5 m before 2026. Unladen it can feel jittery over small bumps, and it settles with weight in the bed. Expedition Portal found it quieter and more comfortable than the wagon. Top Gear noted the light rear end can lose grip on slippery climbs, which is where the lockers and all-terrain tires help.

What fuel economy does it get?

Australian test-cycle (ADR) figures are 12.6 L/100 km for the petrol and 10.5 L/100 km for the diesel. Edmunds lists 14 mpg combined for the 2026 US truck. Towing a big caravan with the B57 diesel Grenadier, Caravan World saw mid-to-high 20s in L/100 km. The tank holds 90 litres. Caravan World says about 10% of Australian Grenadier buyers fit a Brown Davis long-range tank, which adds 78 litres.

Which year should I buy?

The engines haven't changed, so the main question is steering. MY2026 trucks have the variable-ratio box, about a 5% tighter turning circle, better HVAC and a quicker way to silence the speed-limit chime. Earlier trucks can be fitted with Owl's steering pump upgrade, which Owl says fits both the Grenadier and Quartermaster. Whichever year you buy, run the VIN for recalls.

What camper and canopy options exist?

Dirtbox Overland sells a canopy camper made for the Quartermaster bed for $11,499, and Norweld makes full-length, compact and half canopies plus trays. Leitner Designs makes a full-length roof rack (375 lb on-road, 200 lb off-road). INEOS Forum owners have fitted Dirtbox caps. Ineos's own accessory list includes a canvas tonneau, a roll-top cover and a hardtop.

Building one

Who makes the good stuff, where owners gather, and who to watch.

Common modifications & who does them

CANOPY & CAMPERThe bed is a pallet-width box with an upright spare in it. Canopies and canopy campers turn it into secure storage and a bed off the ground. Watch payload.
SUSPENSION & LOAD SUPPORTRestores ride height under a canopy and gear, and makes room for 34–35 in. tires. The springs and air bags fit both Grenadier bodies.
ROOF RACKPuts the tent, solar panels or the spare up top and leaves the bed free. The Quartermaster rack bolts to the roll cage, not the gutters.
STEERINGPre-2026 trucks have the slow, non-self-centring box. Owl sells a $2,150 pump upgrade that it says works on both the Grenadier and the Quartermaster.
TRAY CONVERSIONOutside the US, the cab-chassis plus an aluminium tray gives a flat, wider deck with drawers and water tanks. That's how the Kaiju was built.
