Fiat Ducato vs Isuzu D-Max

What's the difference?

The latest Fiat Ducato, in MWB MR configuration with optional nine-speed auto, is a competent competitor in the 3501-8000kg GVM segment. Its class-leading two-tonne-plus payload rating would have considerable appeal for those who need to carry exceptionally heavy loads and we couldn’t find any major flaws in its design and performance. However, the warranty is short and there are niggling issues in terms of driver comfort, which if addressed would increase the Ducato’s appeal.

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 MWB MR's front-wheel drive chassis rides on a 3450mm wheelbase with 12.5-metre turning circle. It’s 5413mm long, 2050mm wide and 2539mm tall, so like numerous van rivals in this GVM class it can’t access shopping centre and underground carparks which typically have a 2.2-metre height limit.

Underpinnings are simple and rugged, combining coil-spring strut front suspension with a leaf-spring rigid-tube rear axle that’s well designed for heavy load-carrying, with compressible rubber cones between body and axle that provide a second stage of support. There’s also four-wheel disc brakes, power-assisted rack and pinion steering and ample hard-wearing black plastic protecting the most vulnerable areas of the bodywork from scrapes and dents.

A sealed steel bulkhead separates the cabin from the cargo bay, insulating driver and passengers from load area noise and doubling as a robust cargo barrier. Its sliding window is ideally positioned to allow the driver or passenger to make a quick over-shoulder glance to check that their load is secure. Leg room for the centre passenger is unusually generous, even for tall adults, which would be appreciated by a crew of three.

Interestingly, the rear barn-door windows are heated but there are no wiper/washers fitted. At first this appeared to be an oversight, but having driven the Ducato in heavy rain we were surprised at how spray-free the rear screens remained and how clean they were afterwards.

Our only gripes are that the driver’s left footrest is so short you can only rest your toes on it. It’s a shame the excellent full-length one that resides in the passenger footwell (which of course is the driver’s footwell in LHD models) can’t migrate across the cabin for RHD versions. Driver comfort would be further improved with more rake adjustment in the base cushion.

The small 5.0-inch infotainment screen also makes it difficult to see much detail in the vision provided by the reversing camera. The optional 7.0-inch screen would be an improvement here, but is only available as part of the Comfort and Tech Pack.

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 Ducato’s 2060kg kerb weight and 4250kg GVM results in a huge 2190kg payload rating which dwarfs rivals we've tested including the Mercedes-Benz Sprinter, Ford Transit and its Peugeot Boxer sibling. It's also rated to tow up to 2250kg of braked trailer but given that Fiat does not publish a GCM (Gross Combination Mass) number, we can’t confirm if it can tow that weight while carrying a full payload.

The cargo bay, with a competitive 11.5 cubic metres of load volume, has an unprotected load floor that’s 3120mm long and 1870mm wide with 1422mm between the wheel housings. Therefore, it can easily carry two 1165mm-square standard Aussie pallets or three 1200 x 800mm Euro pallets, held in place by eight sturdy load-anchorage points.

There’s also ample forklift access through either the rear barn-doors, which can swing open to 270 degrees with a combined 1562mm-wide opening, or the sliding side doors with their 1250mm-wide openings.

All doors and walls are lined to mid-height and the raised roof cavity allows even tall adults to stand inside without stooping. It also provides a large and very useful storage area over the driver’s cabin, which is ideal for stowing ropes, straps, load-padding etc.

There’s plenty of cabin storage too, with large-bottle holders and two levels of storage bins in each front door. The dashboard offers numerous open storage bins plus small-bottle/cup holders, a glovebox, large overhead map shelf and storage tray under the driver’s seat. The centre seat’s backrest also folds forward to reveal a handy work desk on the back of it, complete with a spring-loaded clip to hold documents in place, a pen holder and two more small-bottle/cup holders.

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 all-new drivetrain features Fiat’s latest 2.3 litre four-cylinder turbo-diesel with Multi-Jet 2 electronically-controlled common rail direct injection, variable-vane turbocharging, intercooler and Euro 6-emissions compliance using AdBlue. It produces 130kW at 3500rpm and (in automatic models) 450Nm of torque which peaks at 1500rpm. In case you’re wondering, the red ‘180’ body badges denote European metric horsepower.

The new ZF nine-speed torque converter automatic is a sweet-shifting transmission which Fiat claims is designed to optimise the engine’s torque delivery and fuel economy. It has a sequential manual-shift function if required, which could be useful if hauling big payloads in hilly terrain, but works most efficiently when left alone.

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.

Fiat does not publish a combined average consumption figure for the Ducato, but the dash display was claiming 10.2L/100km at the end of our test, which covered almost 300km of which more than a third was with a heavy payload. We also had the auto stop-start function switched off. That consumption figure was very close to our own, calculated from fuel bowser and tripmeter readings, of 10.6L. So, based on our numbers you could expect a real-world driving range of around 850km from its 90-litre 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.

There’s a commanding view for the driver thanks to a panoramic windscreen and clear eye-lines to the truck-sized door mirrors. There’s also reasonable but cluttered vision through the central rear-view mirror, which is partly obscured by the centre seat’s headrest.

The cabin bulkhead is effective in all but eliminating cargo bay noise and engine/wind noise volume is commendably low even on the highway. The highest audible intrusion at those speeds comes from the front tyres, which is acceptable on smooth bitumen surfaces but increases on coarser grades.

Its leather-rimmed steering wheel is nice to use and thanks to the driver’s door moulding and fold-down in-board armrest, there’s evenly balanced elbow support to relieve strain on the neck and shoulders.

The engine and nine-speed auto transmission are well matched, providing energetic performance when prodded and crisp, decisive shifting. Long-legged highway gearing allows 100km/h at 1500rpm (which is also bang on maximum torque) and less than 1700rpm at 110km/h. Ride quality when empty or lightly loaded can get bouncy on bumpy roads, which is not unexpected from suspension with a two-tonne-plus payload capacity.

Our main criticism is insufficient rake adjustment in the driver’s seat base cushion. There’s not enough angle available to stop the driver sliding forwards, requiring constant repositioning that becomes tiring after a while. More rake in the base cushion, combined with a decent-sized left footrest, would solve this issue.

Also annoying is the audible lane-departure warning, which is too loud and sounds like you’re being zapped by a ray-gun in an old sci-fi movie if you step out of line. A less confronting warning would be welcome.

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.

Three years/200,000km warranty looks undercooked compared to the five years/unlimited km offered by some rivals. Scheduled servicing, though, is excellent for hard-working vans at 48,000km/12 months whichever occurs first. Five years of Fiat Professional servicing, based on a total distance of 240,000km, equals $6756.99 or an average of $1351.40 per year.

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.
