Isuzu D-Max vs Jeep Gladiator

What's the difference?

There’s a lot to like about the regular D-Max in terms of standard features, driver-assist tech, and all-round driveability – it’s an impressive 4WD with plenty of appeal as a daily driver.

And the Blade is even better – but not by a lot.

Walkinshaw’s work on the Blade has bolstered that appeal with conversion work, engineering upgrades and fitment of accessories and all of those elements are the kind of sensible changes an experienced 4WDer would usually make to their own stock-standard vehicle via the aftermarket.

And that’s a crucial point with these type of factory-modded vehicles: some people prefer to do the research, sourcing, purchasing and even the fitment of mods and accessories themselves rather than buy a ready-made adventure machine.

However, there’s no denying the convenience of a factory-backed and -accessorised 4WD ute or wagon, and Isuzu and Walkinshaw have proven, in the same way that Nissan and Premcar have, that these kinds of collaborations can yield positive results.

Do you need a Blade? No, and an LS-U+ might better suit your lifestyle. But do you want a Blade? Many a D-Max fan would say “Yes!” without hesitation.

The Jeep Gladiator Rubicon is a very capable off-roader and it's not as terrible on-road as some people might assume.

But while it's a whole lot of fun to steer around on the dirt, it lacks the versatility, safety tech, and refinement that would shift it from simply being a decent hard-core 4WD ute to a good general-purpose vehicle.

However, by focussing on those factors, you're in danger of missing the Gladiator's point entirely. This is a purpose-built 4WD fun machine, which is perfect for its intended use. But, the problem is, it's not perfect, or even very good, at anything else.

The Blade’s distinctive look builds on the D-Max’s most recent refresh treatment, in which the ute received new headlights, a bigger grille, redesigned wheels, and three-tier LED tail-lights.

In terms of dimensions, the Blade is 5308mm long (with a 3125mm wheelbase), 1810mm high and 1910mm wide (excluding wing mirrors).

In comparison, the LS-U+ is 5285mm long (with a 3125mm wheelbase), 1790mm high and 1870mm wide (excluding wing mirrors).

So, the Blade is longer, taller, wider (with wider wheels and wheel tracks, and 23mm-wider wheel-arch flares), beefier and more imposing than its standard stablemates.

Also, at a listed kerb weight of 2204kg, this ute is 89kg heavier than the LS-U+.

Exterior Blade extras (all of these are satin black) include front grille with ‘ISUZU’ lettering (and integrated, tinted 112-watt lightbar), front bumper cladding, fender flares with integrated air curtains, ‘BLADE’ lettering across the tailgate, tailgate badging, decals on the front bar, bonnet, doors and tailgate, tubular sidesteps, and a one-piece extended sports bar with integrated stop lamp.

It also gets widened mud flaps, an individually numbered 'BLADE' identification plaque in engine bay, 'Basalt Black' tailgate and door handles and door mirrors.

Inside there are ‘BLADE’ embroidered head rests, 'BLADE’ embroidered floor mats, 'BLADE’ embossed scuff plates, and an individually numbered 'BLADE' identification plaque on the transmission selector surround.

Everything looks good, except...

This vehicle would be a whole lot more appealing without the cheesy katana-style stickers everywhere and the huge ‘BLADE’ emblazoned on its rear end. The ‘Blade’ mentions on the scuff plates and on the front-seats head-rests are about all the decoration it should have.

The decals are shaped to bring to mind the blades of samurai swords I guess, but they look more like ice hockey sticks to me – and they shouldn’t be there.

This ute would benefit from more of a subtle look – it’s chunkier-than-thou appearance speaks for itself, so there’s no need for garish tarting up of any sort.

The Jeep Gladiator appears built for purpose if your purpose is to head bush and have fun. And in Rubicon form it sure looks like it's capable of tackling hard-core 4WDing.

The Gladiator looks very much like its stablemate, the iconic Wrangler, with its chunky front end and blocky body.

It has more than the inkling of a US-style pick-up's presence at 5591mm long (with a 3488mm-long wheelbase), 1894mm wide, 1909mm high, and with a kerb weight of 2242kg.

Isuzu could never be accused of ever sacrificing substance for style in the D-Max and that remains true in the Blade. 

Not a lot separates the LS-U+ and Blade in terms of functionality or comfort because they share essentially the same interior with only a few differences.

The interior here is at heart a workhorse’s cabin with no fancy-schmancy elements that might spoil this ute’s primary purpose: work … and a fair dose of play, of course.

The latest round of D-Max upgrades brought with it enhanced interior materials, a new 9.0-inch touchscreen multimedia system as well as upgraded functionality across all dash tech, and more charging spots for smart devices.

And the Blade treatment doesn’t add anything other than the aforementioned style tweaks to that – which is fine.

The cabin has a pleasantly familiar feel about it and it’s an easy space in which to swiftly become comfortable and to figure out where all controls are (on-screen and real switches, buttons and dials) and how to use them. 

The interior is adequately spacious with nicely supportive seats upfront and a reasonably comfortable bench-style pew for the three people at the rear. 

The Blade has leather-accented upholstery, but there are expanses of durable plastic surfaces to cope with real-life mess.

Charging options are numerous – a mix of USB-A, USB-C and 12V upfront, and USB-A for the second row – and storage places include recesses for your everyday carry gear, a suitably deep centre console, as well as dual cupholders upfront and cupholders in the fold-down armrest, and bottle holders in the doors.

Back-row passengers get USB ports, directional air-con vents and shallow under-seat storage.

The tub is 1570mm long (at floor level), 1530mm wide (1122mm between the wheel-arches) and 490mm deep. It is a double-walled tub, with an under-rail tub liner, two cargo tie-down points, and it has tailgate assist.

Tub options for D-Max owners include a tonneau or roller cover (which offers at least some degree of security from thieves, and protection from rain, mud, snow etc), or an Isuzu or aftermarket canopy, although a canopy impacts the versatility of the load space because once it’s an enclosed area it makes it more difficult to carry long, awkward and/or large loads in the tub.

You have to give Jeep's designers credit because they know their outdoorsy stuff. The Gladiator's interior is nothing if not practical.

The ute has a squared-off and action-ready interior that seems up to the task of copping the dirt of an outdoors life.

The cabin feels like it's water- and weather-proof, even if that may not literally be the case. 

It's a snug interior and build quality generally feels solid.

The 8.4-inch multimedia touch screen is clear and easy enough to read while on the go, but it's too small. The Jeep's 'Uconnect' system is simple enough to get your head around and Apple CarPlay and Android Auto are easy to get working.

There's also a 7.0-inch LED driver-information display, which shows tyre pressure, tyre-fill alert, digital speed readout and more.

All controls, dials and switchgear are chunky, making for easy operation, no matter how bumpy the terrain you're traversing is.

The reach-and-rake-adjustable steering wheel incorporates audio, voice and cruise control controls.

Storage spaces are few, but at least they're well suited to adventure, such as tensioned mesh pockets on the doors and seat backs and small spaces with textured bases for your bits and pieces.

There are two USB-A ports and a USB-C port up front and two for back-seat passengers. There's also a 230V outlet up front on the centre console.

Seating is decent all-around but anyone taller than Tom Cruise's stunt double has to mind their head so they don't thump it on the unforgivingly hard ceiling of the detachable top.

There's a shallow storage space under the rear seat and, when that 60/40 split rear seat is folded flat, there are LED lights behind to illuminate the narrow storage space in the rear of the cabin, where there are also storage nets.

The tub's load space is 1442mm wide – 1137mm between the wheel arches so not wide enough for a pallet – and it is 1531mm long. Load height is 885mm at the tailgate.

The tray has integrated tie-down points and under-rail LED lights.

Payload is now a claimed 693kg, which is better than its previous 680kg but still rather ordinary when compared to a lot of dual-cab utes available in Australia.

Gross vehicle mass and gross combined mass are listed as 2935kg and 5656kg, respectively.

The Gladiator has a maximum towing capacity of 750kg (unbraked), and its 2721kg braked towing figure is a let-down against the 3500kg capacity of most other rivals.

This is a ute better suited to weekend camping trips than load-lugging work duties.

Another bonus for tourers though: the spare wheel is a full-size steel one.

The 2023 Jeep Gladiator Rubicon has an official list price of $87,250, excluding on-road costs.

This variant's more notable standard features include Jeep's 'Rock-Trac Active On-Demand II' 4x4 system (4:1 transfer case), 'Tru-Lok' front and rear locking differentials, sway-bar disconnect, Tenneco 2.0-inch diameter aluminium-bodied shocks (front and rear; Fox shocks on previous versions), a 'TrailCam' off-road camera, selectable tyre-fill alert, BFGoodrich Mud Terrain tyres (255/75 R17), and 17-inch machined-black alloy wheels.

It also has an 8.4-inch touchscreen multimedia system (with navigation, Apple CarPlay and Android Auto), as well as LED headlights/tail-lights/daytime running lights/fog lights, forward collision warning, plus adaptive cruise control, blind-spot monitor with rear cross-path detection, remote proximity keyless entry and a nine-speaker Alpine Premium audio system.

Gladiator paint choices include standard black and 'Bright White', as well as $895 premium paint options including 'Sarge Green', 'Silver Zynith', 'Firecracker Red', 'Sting Grey', 'Hydro Blue', 'Granite Crystal' and 'High Velocity' (yellow/green).

The accessories range for the Gladiator is a line-up of more than 70 bits of gear, and includes everything from Jeep windscreen sunshades to a cargo bed storage system (drawers).

The D-Max Blade has the D-Max line-up’s 3.0-litre four-cylinder turbo-diesel engine – producing 140kW at 3600rpm and 450Nm from 1600 to 2600rpm – and it’s matched to a six-speed auto. 

Just to be clear: the Blade does not have any power or torque advantages over the standard D-Max.

This engine and auto combination form part of a proven powertrain and while this ute is sluggish when accelerating and it’s not the most dynamic vehicle to drive, the D-Max has a real tractability about it that negates most other flaws. 

It has part-time 4WD, with high- and low-range. Driver-assist tech, such as rough terrain mode, has been tweaked with the aim of making Isuzu 4WDs perform off-road even better than before.

The Gladiator Rubicon has the Wrangler's 3.6-litre Pentastar V6 petrol engine (209kW at 6400rpm and 347Nm at 4100rpm) and eight-speed automatic transmission.

The V6 has a lot of punch for on- and off-road driving and plenty of low-end torque for low-range 4WDing and, matched with the eight-speed auto, it's a well-proven team-up that consistently works well.

Official fuel consumption for this D-Max is 8.0L/100km on a combined cycle. 

Actual fuel consumption on this test, from pump to pump, was 10.6L/100km for the D-Max. 

The D-Max has a 76-litre fuel tank so, going by those fuel consumption figures, you should be able to get a driving range of about 717km from a full tank.

The Gladiator Rubicon has listed fuel consumption of 12.4L/100km on a combined cycle. 

On test I recorded actual fuel consumption of 12.9L/100km, from fill to fill.

The Gladiator has an 83-litre tank, so, going by my on-test fuel-use figure, you could reasonably expect a driving range of approximately 643km from a full tank.

The D-Max has never been a stand-out performer on-road in the ute segment, but it’s never been atrocious either.

The engine and auto combination yield a solid drivability rather than any liveliness, which works fine in this ute package.

Suffice to say, the D-Max is consistently middle of the pack when it comes to ride and handling or refinement comparisons, but again that suits this ute package. 

Besides, the D-Max is a body-on-frame ute with leaf spring rear suspension, so it can’t be expected to produce sportscar-like driving qualities, though the most recent upgrades to the D-Max did improve the steering and driver-assist tech.

But then came the Blade project, which wasn’t about improving the ute’s around-town driveability: Isuzu brought in the Walkinshaw Automotive Group, one of Australia’s leading automotive engineering firms, to make a version of the D-Max that was even better at off-roading than the standard unmodified D-Max.

Boiling down thousands of kilometres and man-hours of Walkinshaw’s work on the Blade into the most salient points for this yarn does not accurately reflect the effort of those involved in the years-long process … but here goes anyway: Walkinshaw has designed, engineered and remanufactured some of Australia’s most iconic nameplates, and, while the Blade reworking doesn’t introduce any new mechanical or driver-assist tech set-ups to the D-Max package, the introduction of new all-terrain tyres, wider wheel track and Aussie-tuned suspension (including Monroe 35mm MTV twin-tube dampers with lifted spring seats) has added a welcome measure of composure to this ute’s on-road behaviour.

And Isuzu big wigs must be feeling a bit chuffed at this point in time because Walkinshaw’s off-road mods have produced real results where they count most: off-road.

The standard D-Max in LS-U+ guise is an impressive 4WD ute, but the Blade version is a touch better on a variety of terrain for a number of reasons.

For starters, the Blade’s Walkinshaw-developed suspension set-up, with those 35mm twin-tube dampers in the mix, yields a more agreeable drive, with more comfort and better chassis control than a regular D-Max on fast dirt tracks and corrugated gravel roads. It manages to subdue most of the lumps and bumps you’re bound to drive over on your way to a beach- or bush-camping destination.

The Blade’s wheel track – at 1602mm, 32mm wider than the LS-U+’s 1570mm – gives this ute a slightly more planted posture than its standard stablemate for improved stability and handling.

And while the Blade’s tyres aren’t gung-ho mud-terrains or something similar, its 275/65R17 Goodyear Wrangler Duratrac RT all-terrain tyres do work sufficiently well on-road and off.

For low-range 4WDing, the Blade has all of the D-Max good stuff – including a tractable engine with plenty of low-down torque and a recalibrated off-road traction control (part of the most recent D-Max upgrades) – but its ground clearance (244mm vs the LS-U+’s 240mm) and off-road angles (29.2° approach, 19.2° departure and 25.2° breakover vs the LS-U+’s 30.5°, 19.0°, and 23.8°) don’t represent as much of an improvement over its stablemate as you’d expect in a vehicle touted by Isuzu as “an off-road ute without compromise” and “an unparalleled combination of off-road performance and rugged reliability”.

The Blade feels vulnerable to underbody knocks from rocks and the like, but it has 3mm-thick steel bash plate protection so there’s no need to lose any sleep over a few ‘rubbing dirt’ moments.

Its tubular sidesteps at least seem hardier than the standard D-Max’s sidesteps and seem able to cop knocks from rocks without crumpling.

If there’s any need for a vehicle recovery, the Blade has eight-tonne load-rated recovery points (with bracing between chassis rails for torsional rigidity) to work with.

Also, if you’re thinking about using your Blade as a touring platform, at a listed kerb weight of 2204kg, it is 89kg heavier than the LS-U+, and its payload is 896kg (down form the LS-U+’s 990kg). GVM is 3100kg, GCM is 6000kg.

Towing capacities remain at 750kg (unbraked) and 3500kg (braked).

It's certainly an experience, but the Gladiator is not as atrocious on-road as you may assume.

This vehicle is a lot of fun to drive because it demands a lot of attention and input to keep it on target.

The steering is floaty, with plenty of play in the wheel and understeer through corners, and there's a fair bit of tyre rumble from the BFG muddies.

The wing mirrors generate noticeable wind noise, but the Gladiator's not as awkward or unrefined as you might expect.

Because it's essentially a stretched Wrangler – with a 787mm longer body and a 480mm longer wheelbase than its stablemate – the Gladiator has a solid stance on the road and, for such an unashamedly off-road-oriented vehicle, it feels even more settled and composed than the Wrangler does on sealed surfaces.

This 2242kg ute is built for tough fun with a body-on-frame design and reinforced chassis, but the Gladiator manages to be nimble around town.

Ride quality is generally impressive with this ute cruising comfortably on live axles front and rear with coil springs and, in 2023 onward versions, Tenneco shocks all-around rather than the previous Fox Shocks set-up.

Aspects of the Gladiator experience will annoy some people. Visibility is compromised in all directions, the throttle is touchy, the 13.6m turning circle may add a degree of difficulty in attempts at fast turnarounds (on a city street or in a busy country pub car park) and all that driver attention and input the Gladiator demands of its steerer will become tiresome for a few drivers.

But, as expected, the Gladiator's true spirit is only ever fully revealed when you head off-road. It's a hell of a lot of fun in the dirt. Drop tyre pressures, do up your seat belt and let the Gladiator off the leash.

The 'Trail Rated' Gladiator is loaded with off-road mechanicals, from a 4X4 system with 4:1 low-range (contributing to a 77.2:1 crawl ratio), front and rear diff-locks, heavy-duty Dana 44 axles (front and rear), sway-bar disconnect and BFGoodrich Mud Terrain tyres, as well as a stack of driver-assist tech aimed at making you feel like Australian 4WD expedition legend Ron Moon.

Shocks engineered for off-roading add a welcome dimension of comfort and handling to the Gladiator on fast dirt and gravel tracks on the way to your chosen off-roading destination.

That 77.2:1 crawl ratio means nothing to most of us until you have the opportunity to experience the feeling of all that terrain-gripping torque for yourself.

In 4WD low-range first gear, and with both diffs locked, the Gladiator feels unstoppable. It climbed with ease a short steep rocky hill where I've seen drivers of modified vehicles opt for the ‘chicken' tracks either side.

The only thing is, because of the Gladiator's 3488mm-long wheelbase and 18.4-degree ramp-over angle, there's a real risk of bellying out or at least grinding the undercarriage on earth when you crest these steep hills, which is why you must drive with concentrated focus.

But that's part of the fun. It really is a driver-direct experience. You need to be aware of everything that's going on, you never feel like you're one step removed from the situation, or the terrain or the consequences of your driving… you feel dialled into the terrain and that's guaranteed to put a smile on any 4WD enthusiast's face.

Besides, the Gladiator does have substantial underbody skid-plates, protecting the fuel tank, transmission and transfer case, as well as heavy-gauge tubular steel rock rails to soak up off-road hits.

With an approach angle of 40.7 degrees, a departure angle of 25.1 degrees and a listed ground clearance of 249mm and a wading depth of 760mm, the Gladiator has decent off-road measures.

Suspension travel is okay, but to get even more stretch, you can hit the sway-bar disconnect button to drop a wheel to the dirt – or as close as possible depending on how deep the ruts are.
 
The Gladiator has 'Selec-Speed Control' (effectively an adjustable low-speed cruise control for 4WDing that can be set between 1.0-8.0km/h), and 'Off-Road+', which tweaks throttle and traction control, among other systems, to best suit the terrain.

It also has a forward-facing off-road camera so the driver has a chance to see any obstacles that might otherwise go unnoticed until it's too late, such as branches, rocks, tree stumps and hard rubbish.

The Gladiator has a three-star ANCAP safety rating from testing in 2019.

Its safety gear includes four airbags, full-speed forward collision warning plus, reversing camera, adaptive cruise control, blind-spot monitoring, rear cross-path detection, tyre-pressure monitoring system, and more.

It also has hill start assist, hill descent control, and trailer sway control.

It has dual ISOFIX child seat anchor points and three top-tether attachments in the rear seat.

The D-Max has a six-year/150,000km warranty and seven years of roadside assistance when you have your D-Max always serviced at a participating Isuzu ute dealer. That warranty is okay in terms of years, but unlimited kilometres would be a welcome sweetener.

Service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped-price servicing covers the first five scheduled services for 24MY and later vehicle models (up to five years/75,000km - whichever occurs first) – at a flat price of $449 for each service.

The Gladiator has Jeep's five-year/100,000km factory warranty, five-year capped price scheduled servicing, and lifetime roadside assistance.

The first five services are capped at $399 each and scheduled servicing is due every 12 months or 12,000 km, whichever comes first.
