Holden Trailblazer vs Isuzu D-Max

What's the difference?

The Trailblazer is a solid all-rounder and deserves the consideration of those in the market for a decent seven-seater 4WD. It does everything well without ever really excelling at any one thing.

Is it fantastic? No. Is it a game-changer? No. Does it represent pretty good value for money in the grand scheme of things? Yep. 

The pick of the bunch for me is the LTZ – solid, off-road capable, and suburbs-friendly with just a hint of leather-appointed class. In the LTZ, you get everything worthwhile in the Trailblazer mob and if you’re a family man you won’t feel the need to fork out an extra $1000 for the Z71’s try-hard window dressing.

The Trailblazer is a mostly comfortable SUV wagon, stacked with features and is well worth your consideration if the Isuzu MU-X, Pajero Sport and Toyota Fortuner don’t float your boat.

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 Trailblazer is a solid-looking wagon – all clean, tight lines from front to back – and overall it has a real squat and substantial presence. If we’re going to get all ‘fancy Dan’ with our hyperbole: chrome-accented daytime running headlights swoop back along the chunky body to slick LED tail-lights. If we’re sticking to basics: the Trailblazer looks good.

Inside, the tweaked interior has a tidy if rather basic feel to it – but that’s not a bad thing in a wagon that will have to cop dirt and dropped ice creams amid the general chaos of day-to-day life.

The leather-trim seats add a touch of class to otherwise family friendly dimensions and environment.

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.

Climbing in is easy enough with a sturdy "overhead assist handle" for all comers and goers.

All of the Trailblazer’s seats are mostly comfortable except they are quite flat and hard, which may prove a hindrance over longer trips. The driver’s seat is six-way electrically-adjustable and there is little in the way of lumbar support.

The second row will better suit two passengers than three for long-distance comfort but there is enough room all round – head, shoulders and legs – to avoid most complaints, for a little while anyway.

Third-row passengers will need to be children or those of a shorter stature to cope with the ‘back of the bus’ squeeze – and even then trips should be kept to shorter distances to avoid an in-car riot. It’s not a terrible place to be, in the third row of this thing, but it’s not ideal either – pretty much in keeping with the rear-row offerings of its rivals.

Back up the front again and the dash design is clear, user-friendly and easy to get used to with day-in, day-out use.

There is a fair bit of storage space in the cabin but some of it is awkward to access and actually use. The glove box is big enough to cope with one or two handfuls of bits and pieces. There is a sunglass holder up near the rear-view mirror.

Passengers in the back also get air vents and manual aircon control.

There are two cup holders in front of the small centre console housing the USB port which, when used, eats into that available space.

All doors have a moulded bottle bulge, which wouldn’t cop our CarsGuide water bottle without forceful encouragement.

The second-row passengers get a fold-down centre arm-rest/cup holder when there’s no one sitting in the middle. Passengers in the back also get air vents and manual aircon control.

With all seats up, if you pack to the roof, there is 235 litres of cargo space at the very rear; with the 50/50 split-folding third-row seats folded down, there is 878 litres; with the second-row (60/40 split-fold and tumble) and the third-row seats down, there is 1830 litres of cargo space. There is a retractable cargo blind stowed away under the floor at the rear.

With the second-row seats folded forward, it is easy enough to get into the third-row seats; no contortionist moves required.

There are two 12-volt outlets in the centre dash; one at the back of the centre console (for second-row passengers); and one in the rear cargo area.

Up top, the roof rails are rated to carry 100kg.

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.

The D-Max Blade has a national drive-away price of $76,990 ($78,900 RRP) at the time of writing (early Feb 2025), so it’s now the most expensive D-Max available, costing about $9000 more than the line-up’s former big Kohuna, the X-Terrain. 

It’s also about $15,000 more than the mid-range LS-U+ on which it’s based.

Our test vehicle had a few extras onboard including the no-cost option premium paint (Sunstone Orange), a tow bar tongue ($215.05), 12-pin plug ($393.25), and an electronic brake controller ($896.05). Those extras fitted at the time of sale attract stamp duty of $80.85. 

Price as tested, according to Isuzu, is $78,687.85.

Standard D-Max features include a 9.0-inch touchscreen multimedia system display (with wired and wireless Apple CarPlay and Android Auto), eight-way power-adjustable driver’s seat, leather-accented upholstery, heated front seats, reversing camera with dynamic guidelines, a rear-diff lock, Rough Terrain mode and more.

Blade extras of substance include lifted suspension (finished in Isuzu red), 3mm-think steel bash plate underbody protection (in Isuzu red), eight-tonne load rated recovery points with cross-bracing, (finished in Isuzu red), and satin black 17x8.5-inch +28 flow-formed alloy wheels with 275/65R17 Goodyear Wrangler Duratrac RT all-terrain tyres.

It also gets a stack of design-related extras which will get a mention in the Design section (below).

Exterior paint choices include 'Moonstone White' pearl, 'Basalt Black' mica, 'Granite Grey' mica or 'Sunstone Orange' mica.

The 2.8-litre turbo-diesel engine punches out 147kW at 3600rpm and its big-gun 500Nm at 2000rpm and is well-matched to a six-speed automatic transmission. This Trailblazer is, on paper, a very good tow vehicle with so much torque available and from down so low.

Its towing capacity is 3000kg (braked), but I’d prefer to see how it fared in a real-world tow test before I pass judgement.

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.

Claimed fuel economy is 8.6L/100km (combined). We recorded 9.6L/100km fuel consumption after 200km of mixed driving, including about 30km of gravel tracks, and 10km of hard off-roading. As mentioned earlier, it has a 76-litre fuel tank.

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 LTZ is 4887mm long (with a 2845mm wheelbase), 1902mm wide (excl mirrors), and 1846mm high. It has a kerb weight of 2203kg.

Its turning circle is 12m but it feels like more of a cumbersome beast when trying to manoeuvre in the bush or in the city, though not enough so for that characteristic to be any sort of deal-breaker.

The tilt-adjustable, electrically assisted steering lacks any reach-adjustment, which is annoying, but it can still be counted on to deliver a precise feel – light at low speeds, heavier at high speeds – when pushing the Trailblazer along at a fair clip on open roads or in and out of corners.

Acceleration seems livelier now; there is more off-the-mark oomph for take-offs and safe, smooth overtaking, even on long gradual climbs, than before. The torquey engine and six-speed auto – with its smooth changes and gear-holding when appropriate – make for a high-achieving combo.

Ride and handling seem better than in Colorado7 guise although the tweaked suspension – Aussie-tuned coil-spring front and coil-spring live-axle rear – and Bridgestone Dueler H/Ts tyres* may account for some of that. However, we did feel some body-roll while driving along back roads, unlike the last time we were in a Trailblazer LTZ. (*The Trailblazer has a full-sized 18-inch spare.)

The locally tuned suspension is, at times, a bit too firm; when we hit heavy bumps and deep potholes on rough gravel tracks several times, we were unsettled because the Trailblazer’s suspension bashed its way over and through.

NVH levels on open-road bitumen can still tend towards the rougher side of things with diesel engine clatter, tyre roar and wind rush clattering a tune on your ear drums.

We completed a series of emergency braking scenarios – on bitumen and dirt – and the Trailblazer’s disc brakes – 300mm at the front and 318mm at the rear – helped rip us into a controlled stop.

Off-road, we had a ball because the beefy Trailblazer seems a much better fit for gravel-track fast blasts and slow-going bush driving than it does for any jaunts in the stop-start city.

Our drive loop included a decent bit of four-wheel driving – coastal sand, bush tracks peppered with rocks of all shapes and sizes, and shallow mud in a dried-out dam. Drive modes can be switched via the centre console dial between 2H, 4H and 4L; high range modes are actually represented by an ‘up’ arrow on the dial; low range is a ‘down’ arrow. Bonus: the Trailblazer’s 500Nm of torque is readily available from way down low.

The Trailblazer has a limited slip diff, 218mm of ground clearance and a wading depth of 600mm, which was never tested as our usual creek crossings were so bone-dry they were more like puddles. Approach, departure and ramp-over angles are 28, 25, 22 respectively.

Its armoury of off-road tech – auto hill-start assist, hill-descent control and more – make it almost unstoppable, straight out of the showroom, for anything demanded of it on a light- to medium-difficulty adventure weekend.

Its 76-litre fuel tank, however, hinders any claim it has to off-road touring potential.

The Trailblazer has 3000kg towing capacity (braked); 750kg unbraked.

Note: Holden has persisted with a system which, when you open a door, the front windows automatically slide down a bit, an action aimed at reducing air pressure when you close the doors. It remains annoying but we still weren’t annoyed enough to actually bother to check the owner’s manual for a possible hack to switch it off.

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).

The D-Max has the maximum five-star ANCAP safety rating.

As standard, it has auto emergency braking (AEB), eight airbags (dual front, curtain, side, driver's knee and far side) and a comprehensive suite of driver-assist tech including forward collision warning, adaptive cruise control, lane departure warning, a tyre-pressure monitoring system and a raft of other driver-assist tech.

Isuzu's Intelligent Driver Assistance System (IDAS) also includes AEB with turn assist, 'Intelligent' adaptive cruise control, traffic sign recognition, lane departure prevention, lane keeping assist, emergency lane keeping, blind spot monitoring, rear cross-traffic alert, rear cross-traffic brake, digital reversing camera and trailer sway control.

The Trailblazer comes with a three-year/100,000km warranty. Lifetime capped price servicing includes a free inspection at one month, then $299 (at nine months/15,000km), $399 (18 months/30,000km), $479 (27 months/45,000km), $479 (36 months/60,000km) and so on.

(At time of writing, the LT was being offered for $45,990 driveway with a seven-year/175,000 warranty.)

Potential problems might include cumulative driveline wear and tear from people towing heavy loads (horse floats, boats etc).

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.
