Isuzu D-Max vs Ram 1500

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.

As with all current-generation Ram 1500s, the Rebel remains one of our favourite full-sized American utes on the Australian market.

Yes, it is not cheap, and a few items standard on the Laramie Sport have been deleted for better or worse, but the Rebel offers better off-road capability without losing any of the regular 1500’s driver enjoyment, comfort, refinement and overall class.

An upsized Ranger Wildtrak with more civility than its redneck reputation suggests.

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.

Essentially, the 1500 Rebel is a Laramie Sport with a few changes to make it look a little more athletic.

Changes include an extra power bulge in the bonnet, a restyled grille treatment, black powder-coated steel bumpers, daytime running spot lights, 18-inch rather than 20-inch off-road alloy wheels and the aforementioned one-inch (26mm-ish) suspension lift – partly as a result of the knobblier tyres, Bilstein off-road dampers and revised springs, all for better clearances.

Speaking of which, that’s why the retractable side steps have been deleted. The approach/departure/breakover angles are rated at 20.9, 22.2 and 19.2 degrees respectively.

That the Rebel loses the RamBox does mean a bit more tub width, but at the cost of 210 litres of hidden storage.

What’s left are mostly visual changes, including a two-tone colour scheme with black paint on the lower sections, extra blacked-out trim, Rebel badges and decals and three grade-specific hues: 'Bright White', 'Flame Red' and 'Hydro Blue'.

Dimensionally, the 1500 is definitely in the next-league up compared to a Ranger or HiLux, with length at 5916mm, width at 2057mm (excluding mirrors – that balloons out to 2747mm with them) and height at 2006mm. Wheelbase is set at 3672mm. Which does wonders for interior space.

Inside, a red and black look pervades, resulting in Rebel upholstery and material applications, but the seats and dash remain pure Laramie Sport – and that’s no bad thing, as the DT series remains the most car-like and refined interior of all the big US utes.

Let’s dive in.

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.

This is as much an interior review as anything else, because the Walkinshaw Automotive Group’s engineers have created nearly 50 unique dashboard parts in the 1500’s transition from LHD to RHD.

These join the hundreds of other items that have been modified throughout the big ute.

Haul yourself up and inside, and what you’re met with is essentially a Laramie Sport, but with a more-athletic vibe due to the red-and-black Rebel trim upholstery. In this evaluation example, the presentation, fit and finishes were exemplary.

Everything seems to be in Cinemascope. The sheer girth of the cabin; the excellent vision afforded by lofty seating as well as the deep windscreen and side windows; the abundance of light showering in from the dual-pane sunroof; wide yet cosy front seats that ensconce you like a bear hug – are there comfier ones out there in the world of utes? We doubt it; and heaps of space for your head, shoulders, arms and legs.

Most people should be able to sleep crossways on the back seat floor.

Back up front, the vast multi-layered dash is conventionally designed, with a 12-inch instrument display ahead of the driver and a long, portrait-oriented 14.4-inch touchscreen (containing a superb premium audio system).

But, unusually, there’s also a 10.25-inch multimedia screen for the front passenger, which isn’t visible to the driver for road-safety reasons.

Drilling into the details, there’s a satisfying attention to design to the instrument dials that you’d expect from an Italian brand – Ram owner Stellantis is partly consisted of Alfa Romeo, Fiat and Lancia, after all, as well as Citroen and Peugeot.

It’s also in the feel and quality of the presentation, as well as the general ergonomics, where most of the controls and switchgear are within reach, readily understood and easily operable – after a few moments taken to learn what’s what.

Confidence and swagger, without being too brash or ostentatious. An F-150, in contrast, seems cheap and hard inside.

Weirdly, given all the room around you, there’s also a sense of being a bit hemmed-in, thanks to the ultra-wide centre console. It houses an attic’s worth of storage capability, and is nicely integrated within the overall dash architecture.

It’s a pity, then, that Ram doesn’t offer a three-person bench seat up front – or, at least, a two-person love seat for the passengers right beside the driver’s bucket. There’s certainly enough space for that.

A half-day with the Rebel failed to showcase too many faults or irritations. There’s too much wind noise coming in at speed due to those elephantine exterior mirrors, there’s no digital radio and not everybody will like the red trim inserts. In this regard the vibe is more garish Germanic than restrained Italianate.

Remember, too, the Laramie Sport’s sliding centre console and reclining rear backrests aren’t fitted to the Rebel.

Not that you’d necessarily miss the latter, since the bench is nicely angled and seems comfortable enough. Obviously, there are acres of space to move and lounge about in, and pretty much all the usual amenities are present.

These include USB ports of both varieties, heated outboard seats, face-level ventilation, cupholders, map pockets overhead lighting, a coat hook, and the glorious sunroof that allows so much light to flood in.

There’s extra storage beneath the cushions as well as in the door panels, while a small portion of the back glass slides open. Apparently, that’s handy for hearing and giving instructions when working with the ute. Clever.

And, of course, so is the massive tub out back, complete with a full-sized spare wheel.

For now, Australia only receives the five-foot/seven-inch – or 1.7m long – tub, rather than the longer 6' 1" option offered in earlier 1500s. The Rebel’s payload jumps 30kg, and still maintains its 4.5-tonne towing capacity.

Note that, with the deletion of the RamBox cargo storage units, load-area width increases, but only by 15mm, and you lose 210 litres of hidden tub storage.

For the record, the tub dimensions are around 1700mm (length), 1295mm (width) and 543mm (height). The upshot is about 1500 litres of cargo capacity.

And, of course, there’s the maximum braked towing capacity of 4500kg (with a 70mm ball), 750kg unbraked, 7771kg for Gross Combined Mass (GCM), 3505kg for Gross Vehicle Mass (GVM) and an 893kg payload maximum.

Finally, a heavy-duty tow bar, 12-pin wiring harness and trailer brake controller are standard equipment.

This isn’t a replacement for the bombastic Ram 1500 TRX, which has sadly disappeared along with the classic Hemi V8 (though it may come back sometime in the future), but rather an adjunct to the base Laramie Sport. Just with more off-road sportiness.

Like all 1500s, as well as the conceptually-similar Silverado 1500, Ford F-150 and Toyota Tundra big utes, the Rebel is fully-assembled in the United States in left-hand-drive form, then shipped to and remanufactured in Melbourne for right-hand-drive.

This is no small task, with the Ram boasting hundreds of new and/or modified parts, needing over 80 man-hours of labour in the process.

Hence the high prices – with the Rebel matching the Laramie Sport at $141,950 (all prices before on-road costs).

More than just a sticker pack, the Australian Rebel includes one-inch higher-riding suspension, Bilstein off-road shocks, 32-inch all-terrain Falken Wildpeak 275/65R18 tyres, an electronically locking rear differential, underbody skid plates, a higher payload, special off-road cruise control and a so-called 'Power Bulge' bonnet – though there’s no extra performance under there, sadly, over the Laramie Sport’s existing SST (for Straight Six Twin-turbo).

You’ll need the $159,950 Limited flagship with its High Output SST engine tune for that.

Like the Laramie Sport, the Rebel seems almost sumptuously equipped, and includes goodies like a separate 10.25-inch multimedia display for the front passenger as well as a 14.4-inch central touchscreen and a 12.0-inch electronic instrumentation, 19-speaker Harman Kardon audio, dual-pane sunroof, heated seats front and rear, dual wireless phone charging, a sliding back window, power adjustable pedals and a fully-powered tailgate.

These come on top of a spray-in bed liner, cargo tie-down slider rails, LED headlights, wireless Apple CarPlay/Android Auto connectivity, a reversing camera and front and rear parking sensors. Handy in a truck this long.

There’s also a decent wad of advanced driver assist systems too, like autonomous emergency braking and adaptive cruise control. More on those in the safety section later on.

But it also loses some interior items too, like a sliding centre console, a reclining rear bench and 'RamBox' cargo storage, while digital radio is not available at all… which – to paraphrase '80s punk-rocker Billy Idol – might have Rebel owners yell out for more, more, more!

Anyway, there are also a few things missing outside too that are otherwise standard in the Laramie Sport.

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.

Underneath the power bulge bonnet is a 3.0-litre twin-turbo in-line six-cylinder petrol engine known as the 'Hurricane'.

Sharing just five per cent of its parts with Jeep’s version, the Rebel uses the Standard Output (SO) tune, meaning this Euro 5-rated direct-injection unit delivers a heady 313kW of power at 5200rpm and 635Nm of torque at 3500rpm.

The High Output (HO) in the Limited, on the other hand, ups the ante with 403kW and 707Nm.

Compared to the old 291kW/556Nm 5.7L Hemi V8, the Hurricane SO lacks its evocative exhaust burble and effortless low-down grunt, but the figures don’t fib: 7.6 per cent more power and 14.2 per cent more torque.

Tipping the scales at 2615kg, the Rebel returns an impressive 120kW/tonne (versus 109kW/tonne for the V8), resulting in a 0-100km/h sprint-time of just 6.0 seconds, according to Ram (HO: 5.3s). That the Hurricane weighs nearly 60kg less than the Hemi helps.

Torque is sent to either the rear wheels in 2WD mode or all four wheels in 4WD mode via an eight-speed torque-converter auto, that Ram evocatively calls ‘TorqueFlite’ – memories of old Aussie Chrysler Valiants here.

A full-time on-demand transfer case is fitted, offering '2WD High', '4WD Auto' and '4WD High/Low' along with a locking rear differential.

As with all 1500s, there are wishbones up front and the rear axle is a coil-sprung rather than leaf-spring set-up.

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.

Ram says the Rebel returns a combined average of 10.7L/100km, which translates to about 283 grams/km of carbon dioxide emissions. That’s a small improvement over the Hemi V8’s 12.2L/100km and 325g/km figures, aided by stop/start tech. But stirring performance, rather than outright economy are the priorities here, according to Ram.

Brimming the big 98-litre fuel tank with 91 RON standard unleaded petrol should see a theoretical average range between refills of 916km.

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).

If you’re a dyed-in-the-wool Hemi V8 lover and dread the notion that a mere ‘six’ has taken its place in the Ram 1500 – and particularly in the sporty off-road Rebel we have here – then a rethink may be in order.

That’s because, in the spirit of iconic sixes of the past, including Ford Australia’s legendary Barra in the Falcon and Territory, the Ram’s Hurricane should blow any scepticism clear away.

And it’s all in the delivery.

Smooth and sophisticated, the 3.0-litre twin-turbo straight-six idles with a muted rumble at start-up, but then roars off the line with an unexpected and prolonged burst of hungry acceleration.

And the power piles on effortlessly as the revs rise, with the auto seamlessly shifting through each ratio without putting a foot wrong.

Reflecting the interior design’s overall cohesiveness, the powertrain possesses a sophistication that’s far beyond what a big American truck ought to have.

That’s in 'Normal' mode. Choosing 'Sport' ups the stakes, as it also seems to stymie the stability/traction control intervention. Throttle response is noticeably sharper and more urgent, but other than the opportunity to more-easily break traction whilst getting to licence-losing speeds slightly quicker, there seemed little sense in staying in Sport.

This is a very fast ute as it is, and also an enjoyable one to drive, with a level of nuance at odds with its excessive proportions.

Even on wet and windy back roads the Rebel feels connected and controlled at speed.

The steering is appropriately weighted, with a sufficient amount of response for the driver to push on with confidence when taking corners quickly.

Remember, this is a 2.6-tonne-plus full-sized ute on off-road-biased tyres, yet getting into a rhythm and flow with the road is easy. Yes, you feel the mass, but the 1500 also feels taut and secure. And you’re not constantly harangued by over-zealous driver-assist systems going off all the time.

The wishbone front/coil-sprung rear suspension set-up must take much of the credit here, smothering bumps and tracing the groove of the road without jolting or stepping out of line.

Comfortable and quiet, there is a sense of isolation from the outside world that, incongruously perhaps, is in league with better premium SUVs. Again, this is a big American pick-up, remember.

On a few downhill twisty bits, the driver of course feels the shift in mass, but deft handling, adequate grip (great for off-road tyres) and effective brakes mean the Rebel doesn't break a sweat, even through puddles blanketing the bitumen.

Downsides? Well, it's still a large, lumbering truck to drive and park, with an inevitably massive turning circle to make heavy work of manoeuvring this beast around. Regular car park spots are almost always too small.

There's some wind noise rustling around the large exterior mirrors. And a bit of road noise coming through over certain coarser surfaces.

Overall, though, the Rebel behaves way-better than expected – and you don’t often get a chance to say that about a ute. Rapid, refined and engaging from behind the wheel, it is the best-driving full-sized US pick-up by some margin.

What V8!

That’s on road. We also had a brief off-road stint in the Rebel at the ex-Holden proving ground at Lang Lang, and we were pretty impressed with the ability and ease demonstrated over some short but demanding rough-track sections.

We doubt – at nearly $150K – that most buyers will go bush-bashing in this, but it’s good to know the hardware is there underneath to get you through.

Neither ANCAP nor Euro NCAP have tested any full-sized American utes at this stage.

However, the Ram DT 1500 has scored a five-star result in the US National Highway Traffic Safety Administration rankings.

Keep in mind, too, that the Rebel shares the Laramie Sport and Limited’s advanced driver assist systems, ushering safety like AEB (including cyclist and pedestrian detection), 'Forward Collision Warning', rear cross-traffic alert, blind-spot monitoring, a 360-degree camera view, trailer-sway control and tyre pressure monitors.

Additionally, there are six airbags (dual front, front side and curtain), traction and stability controls and adaptive cruise control.

No speed operation data for the AEB and lane support systems are currently available.

Like all Ram DT 1500s, the Rebel includes three child-seat restraining top-tether points fitted, along with two ISOFIX latches in the rear outboard seats.

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.

Ram drops the ball when it comes to warranty.

That’s because, like GMSV’s Silverado range, it only offers a three-year, 100,000km warranty with roadside assistance, which falls short of the rival Ford F-150 and Toyota Tundra’s five-year/unlimited kilometre coverage.

In an era where Chinese rivals are rolling out utes with seven-year schemes, Ram's (and GMSV's) warranty is severely lacking.

Service intervals are at every 12 months or 12,000km, and there is currently no capped-price servicing on offer.
