“The old Defender's spirit with a BMW heart and Italian tractor axles. Huge capability, real quirks, and steering that only got properly sorted for 2026.”

PART 01

Overview

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

The story

In January 2016 Land Rover stopped building the classic Defender after 67 years, and Sir Jim Ratcliffe, the chemicals magnate behind Ineos, took it personally. He approached Jaguar Land Rover about buying the tooling to keep it in production, and JLR declined. So Ratcliffe built a replacement himself and named it after his favourite pub, The Grenadier in Belgravia, where the idea was hatched. Most pub ideas end with a hangover. This one ended with a factory.

A PUB, A GRUDGE AND A CLEAN SHEET

Ineos announced Ineos Automotive in February 2017 to do the job, and the work ran under the codename Projekt Grenadier. Toby Ecuyer led design, and the brief was unapologetically utilitarian: a box-section steel ladder frame, solid axles at both ends and a shape that looks like it was drawn with a ruler because, functionally, it was. The finished exterior was shown online on 1 July 2020, and nobody needed the press release to see which old Land Rover it was mourning.

Land Rover had tried to trademark the old Defender's shape, and Ineos opposed the applications. The UK Intellectual Property Office refused registration for lack of distinctiveness, and in August 2020 the High Court dismissed JLR's appeal. That cleared the legal road for a square, upright, flat-glassed 4x4 built by somebody else. Ineos had argued the shape didn't work as a 'badge of origin' for JLR, and the courts agreed.

BMW HEART, TRACTOR AXLES, FRENCH ADDRESS

Ineos wasn't going to design an engine from scratch. In March 2019 it signed BMW for powertrains: the 3.0-litre B58 turbo petrol six (282 hp, 332 lb-ft) and the B57 diesel six (245 hp, 406 lb-ft), both through a ZF eight-speed automatic and a Tremec two-speed transfer case with a 2.5:1 low range. Magna Steyr in Austria came on as engineering partner in December 2019, and the program logged a claimed 1.1 million miles of testing, including an outback hot-weather session in early 2022 that got interrupted by a flood.

The axles come from Carraro, an Italian tractor specialist, hung on five-link coil suspension with Eibach springs. Assembly was first planned for a new plant in Bridgend, Wales, announced in September 2019. Then Mercedes put its Smart factory in Hambach, France, up for sale, and in December 2020 Ineos bought it, along with a recently upgraded paint shop and a workforce that had been building Smarts since 1998. The steel floor and shell get 4,068 spot welds, and the body meets the frame in an eight-bolt drop.

WHAT YOU ACTUALLY GET

Specs read like an overlander's wish list: 264 mm of ground clearance, 800 mm wading depth, 3,500 kg (about 7,700 lb) braked towing, permanent four-wheel drive with a lockable centre diff, and front and rear lockers via the Rough Pack, standard on the Trialmaster. Inside, the diff locks and off-road switches live in an aircraft-style overhead panel, there's a low-volume 'toot' horn for cyclists, and the rotary controller is BMW iDrive in work boots.

The catch is the steering. Up to the 2025 model year the Grenadier uses a Bosch hydraulically assisted recirculating-ball box with almost four turns lock to lock, and testers complained about vagueness and wander on the road. Ineos redid it for 2026 with a new variable-ratio worm gear, more assist as you turn, and a hydraulic stop at full lock. If the G 500 is the boxy 4x4 that went to the opera, the Grenadier is the one that stayed behind to fix the fence, and the 2026 truck finally does it without a workout.

SO FAR, SO SQUARE

Series production began at Hambach in late 2022, with first deliveries that December. US buyers got the petrol B58 only, from $71,500, with US-spec trucks leaving France in September 2023. Then the growing pains. NHTSA recalls covered auxiliary-switch wiring that could short (a fire risk), steering ball-joint nuts that needed to be locking ones, and door buttons short on grease that could let a door open on the move. In September 2024 a parts shortage linked to the insolvency of supplier Recaro Automotive stopped the line until January 2025.

Production figures cited on Wikipedia put output at 4,553 Grenadiers in 2023 and about 8,000 in 2024, well short of the 25,000 a year Ineos said the plant could build at full capacity. The Quartermaster pickup joined in late 2023. Owners on the forums report software and electrical gremlins alongside real affection for the thing. It is the closest thing on sale to a new classic Defender with a warranty, and it has the quirks to prove it.

SIDEBAR · THE COURTROOM

Land Rover v. a Shape

Before the Grenadier turned a wheel, it won a court case. Jaguar Land Rover applied to trademark the old Defender's shape, and Ineos, which was building a car with a very similar shape, opposed the applications.

The UK Intellectual Property Office refused registration because the shape lacked distinctiveness. Ineos argued it didn't act as a 'badge of origin' for JLR. JLR appealed, and in August 2020 the High Court dismissed the appeal. A box, it turns out, belongs to everyone.

Specs & capability

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

How it’s built

The Grenadier is old-school where it counts and bought-in where that's smarter. A box-section steel ladder frame carries Carraro beam axles on five-link coils, with permanent 4WD through a Tremec two-speed transfer case. The body is welded at Hambach and bolted to the frame in an eight-bolt drop. The engines and gearboxes are bought in from BMW and ZF. The frame, axles and body are Ineos' own.

Stock285/75R17 (≈34 in)INEOS Forum consensus sweet spot with no rub, but you'll probably need washers under the spare carrier to clear the small rear door. 285/70R17 fits without fuss; DVA Mechanics lists 295/70R17 as 'stock or 40 mm lift'.

Buying one

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

What they cost

Used trucks sit well under new-truck money, so a lightly used 2024 is the value play; the MY2026 steering update is the reason to buy new.

Used 2024, typical Bring a Trailer sale$56.5k–72k
Used 2024, top results$81k–92.5k
New 2026 MSRP (before destination)$71,000–82,995

Based on 12 Bring a Trailer sales of 2024 Grenadier Station Wagons between March 2025 and September 2026 ($56,500–92,500, median about $65,750); two 2025 trucks sold for $61,500 and $63,000, and an armored 2024 was bid to $95,000 without selling. New prices: base $71,000, Fieldmaster and Trialmaster $79,000, Black Edition $82,995, plus about $1,995 destination. Prices move; checked October 2026. See live listings below.

What to check before you buy

  1. 01
    Run the VIN for all three US recalls23V828 (auxiliary switch relay wire trapped under a fastener, fire risk), 23V903 (non-locking nuts on the steering rod ball joint) and 25V147 (door button assemblies short on grease; 7,022 trucks built July 6, 2023 to April 19, 2024). All are free dealer fixes. Ask for proof they were done.
  2. 02
    Ask about software and module historyForum owners report fuel 'implausibility' warnings that took more than one reflash, false steering warnings, failed modules and unexplained messages. A truck with documented updates and a quiet dash is worth more than one with a thin service file.
  3. 03
    Drive it on a real roadPre-2026 trucks use the slow Bosch recirculating-ball box that reviewers called vague and wandering. Some owners love it, some fit aftermarket stabilizers or pump kits. MY2026 got a new variable-ratio steering gear. Know which one you're buying.
  4. 04
    Check for water in the doors and cabinOwners have reported rear doors holding water after a wash, condensation, door seals coming off and a kickplate whose adhesive let go. Look at door bottoms, carpets and seals.
  5. 05
    Check the oil level and the break-in serviceOne owner got a low-oil message at 12,000 miles. Many owners did an early break-in oil change (500–1,000 miles was the dealer advice quoted on the forum). Ask whether it was done and check the dipstick reading in the menu.
  6. 06
    Confirm the Rough Pack if you want lockersThe centre diff lock is standard, but front and rear lockers come with the Rough Pack ($2,850 on base and Fieldmaster at launch; standard on Trialmaster). Look for the locker switches in the overhead panel.
  7. 07
    Inspect any lift and big-tire installAgile Offroad warns that lift height changes can damage the factory driveshaft. On trucks with 285/75s or bigger, check that the spare clears the small rear door, and look for tire rub caused by a body sitting off-center on the frame.
  8. 08
    Understand the parts and dealer networkIneos is a young brand with a small dealer network, and the factory stopped from September 2024 to January 2025 over a parts shortage. Powertrain parts are BMW and ZF, but body and chassis parts come through Ineos. Ask the local dealer about parts lead times.

Spotting the real thing

Every Grenadier looks the same from 20 paces, but lockers, steering and trim packs vary a lot.

  1. ID
    Lockers (Rough Pack)The centre diff lock (lever) is standard. Front and rear lockers come with the Rough Pack, standard on the Trialmaster and a $2,850 option on base and Fieldmaster at US launch. Look for the locker switches in the overhead panel.

Baseline service, the repairs you’ll actually do, and where the manuals live.

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.

Dealer first-service packages include a suspension retorque and drain clearing. Run the VIN for open recalls (door button 25V147, steering ball-joint nut 23V903, aux switch panel 23V828) before anything else.

Battery & charging[CONFIRM IN MANUAL]Test at purchase and every service

Dealers include a battery health test in the annual service. Trucks that sat on a lot often have a tired battery, which causes odd electrical warnings.

Asked on every forum

Ineos Grenadier Station Wagon questions, answered

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

From the factory the Grenadier rides on LT265/70R17 or LT255/70R18 (about 32 in.). INEOS Forum owners report 285/70R17 fits with no problem. 285/75R17 (about 34 in.) is the popular sweet spot: owners report no rub on stock suspension, but you'll probably need a couple of washers under the spare carrier to clear the small rear door. DVA Mechanics' fitment guide lists 295/70R17 as 'stock or 40 mm lift' and treats 35-inch tires (315/70R17) as a 2-inch-lift job. A few forum owners report squeezing 35s onto aftermarket wheels without a lift, but treat 285/75R17 as the practical stock limit.

SOURCE · INEOS FORUM · BIG O TIRES · DVA MECHANICS
How much can it tow?

3,500 kg braked, about 7,700 lb (GearJunkie lists 7,716 lb). That's well above a Wrangler's 2,495 kg in Australian spec. Payload is about 1,680 lb in US figures, so a heavy trailer plus a fully loaded overland build will run into the GVWR before the hitch rating.

SOURCE · MOTOR AUTHORITY · GEARJUNKIE · GOAUTO
What fuel economy does it get?

Not much. The EPA rates the 2024 petrol Grenadier at 15 mpg city, highway and combined, and the Trialmaster at 14 mpg on premium fuel. The tank holds 90 litres (about 23.8 gal), which gives a range of roughly 350 miles in mixed use at the EPA figure, less with a roof tent and big tires.

SOURCE · FUELECONOMY.GOV · TOP GEAR
How much weight can go on the roof?

150 kg (330 lb) dynamic, meaning while driving, and 420 kg (925 lb) static, meaning parked. That's enough for a rooftop tent with people in it. Front Runner's Slimline II kit installs with no drilling and weighs about 57 kg (126 lb) itself, so count it against the dynamic limit.

Can I get the diesel in the US?

No. In the US and Canada the Grenadier and Quartermaster come only with the BMW B58 3.0 petrol six, 282 hp and 332 lb-ft. The B57 diesel (245 hp, 406 lb-ft) is sold in Europe, Australia and other markets.

Does it have lockers, and how does the 4WD work?

It has permanent four-wheel drive through a Tremec two-speed transfer case (2.5:1 low), with a centre diff lock on a lever. Front and rear lockers come with the Rough Pack, which also adds BFG KO2 tires. It's standard on the Trialmaster and was a $2,850 option on base and Fieldmaster trucks at US launch. The locker switches are in the overhead panel.

What oil does the B58 take and how often should I change it?

An owner quoting the manual on the INEOS Forum lists 6.5 L of 0W-20 meeting ACEA C2 / BMW LL-17FE. Check your own manual, since the oil forums note the US manual is vague. One owner reports the manufacturer schedule as every 12,000 miles. Many owners do an early break-in change (500–1,000 miles on dealer advice) and then change it every 5,000–7,500 miles, especially if they tow.

Is the steering really that bad?

Before 2026, it's slow: a Bosch hydraulic recirculating-ball box with almost four turns lock to lock, which The Drive found wandered on the highway and was heavy when parked. Some owners like it off-road, and Owl sells a $2,150 pump kit and a Fox stabilizer. For MY2026 Ineos fitted a variable-ratio worm gear with more assist and a tighter on-center feel. GearJunkie called it 'a big leap forward'.

Which years should I buy or avoid?

There's no bad engine to avoid, since every US truck has the B58. The early US trucks (MY2024) carry all three recalls, so get proof they're closed. MY2026 brings the revised steering, HVAC and driver-assist tweaks plus more than 40 smaller changes. If you plan to drive a lot of highway miles, 2026 is the one to buy.

Is it reliable?

It's too new for a long-term verdict. The BMW six and ZF eight-speed are widely used and well proven elsewhere. Owner reports focus on electronics: modules, false warnings, software reflashes, sticky door buttons and water ingress, plus three US recalls. Most owners on the forums still sound happy, but a good dealer matters more than usual.

SOURCE · INEOS FORUM · NHTSA
How capable is it off-road out of the box?

Very. It has 264 mm of ground clearance, 800 mm wading depth, and approach, breakover and departure angles of 35.5°, 28.2° and 36.1°, with solid axles and up to three locking diffs. GearJunkie noted there's no disconnecting sway bar, but the soft coils still articulate well.

Building one

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

Common modifications & who does them

SUSPENSION LIFTGives room for 285/75s and up, and restores ride height under bumpers, winches and roof tents. Eibach, the factory spring supplier, makes a Pro-Lift set (about +2.5 in. front, +1.2 in. rear). Watch driveshaft angles.
STEERINGThe pre-2026 steering is the Grenadier's most common complaint. Owners fit pump upgrades and dampers to improve on-road feel.
SPARE TIRE CARRIERTires bigger than about 33 in. crowd the small rear door, wiper and camera. A relocation bracket moves the spare out of the way.
ROOF RACKThe roof is rated for 150 kg dynamic and 420 kg static, so it's made for a tent. Front Runner's kit installs with no drilling.
BUMPERS & WINCHThere's a factory winch option, but aftermarket bumpers add approach angle, protection and a proper winch mount.
ARMORA full-length skid plate protects the transfer case, tank and lines when the Carraro axles are articulating over rocks.
