Isuzu D-Max vs Lexus RZ450E

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.

There are sportier EVs out there, there are more tech-savvy EVs out there, but few adhere to the luxury promise quite like the Lexus RZ, particularly at its price point.

It’s this primary characteristic which sets the RZ apart from the pack for me, and while it might not be for every first-time EV adopter, it nails the brief for the existing Lexus buyer while providing a ‘luxurious’ alternative to many of its firmer, sportier and less approachable rivals.

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.

I don’t think the RZ will be for everyone, but it has some very cool details and interesting angles, regardless.

It maintains the signature Lexus face, but this time has sunk the ‘spindle’ pattern deep into its plastic grille, making for a clean nose, but perhaps one which is a little too blank for some. No doubt it needs this smooth look to maintain as low a drag coefficient as possible.

Closer inspection reveals clever detailing, like the way the spindle pattern fades into the corners, and the whole look is lifted by how wide the car is. 

Sports Luxury versions are lifted further with contrast panels accentuating the width and shape.

My favourite angle of the RZ is the rear three-quarter. The coupe window line, split spoiler design, and cool strip tail-light, complete with three-dimensional Lexus branding, looks as contemporary as it gets, not to mention sportier and more intriguing than even some of its rivals.

Savvy EV buyers might know the RZ shares its platform and overall shape with the upcoming Toyota bZ4X and its Subaru Solterra spin-off, and while those two cars look near-identical from the outside, Lexus has clearly had a lot more creative licence with the design of its take on the formula.

Inside is perhaps where this car feels the most Lexus, however. The interior design is almost entirely unrecognisable when compared to the bZ4X, with Lexus going to town with its curvy, intricate design language, and plush detailing throughout.

Padded synthetic leather trims, which match the seats, adorn the doors, which are swapped out for ultrasuede in the case of the higher-grade Sports Luxury.

And Lexus has opted for a deep-set digital dash and massive touchscreen in place of the small column-mounted screen and tablet multimedia of its Toyota and Subaru relations. 

Everywhere you look, though, there’s attention to detail, with interesting material choices from the wacky carpet to the detailing on the centre console and in the door cards. It’s unmistakably Lexus, and feels premium.

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 RZ benefits from its electric-from-the-ground-up 'e-TNGA' platform, which offers an almost flat floor, wide, spacious cabin (despite its coupe-look rear) and there are plenty of clever touches throughout to enhance practicality.

The doors each offer a pocket with integrated bottle holder up front, there’s a wide centre console with a set of large bottle holders, and the clever dual-hinged armrest console which appears in other Lexus products, and a large bay under the multimedia unit which houses additional storage alongside the wireless charger.

Interestingly, the RZ doesn’t have a glove box on the passenger side, as this area is reserved for the infra-red projector in the Sports Luxury grade. 

Instead, the car has a cutaway underneath the bridge-design centre console for additional storage. It’s a welcome and surprisingly large area which also houses a 12V power outlet. However it’s a little tricky to reach when seated up front.

Adjustability feels good for the driver with decent leg and headroom, alongside a tilt and telescopic steering column.

There are dials for the climate controls and a centre dial for the volume adjustment, although there are still many functions - from drive mode to essential safety toggles - that are buried more than one menu deep in the touchscreen, and therefore a little clumsy to jab at while you’re driving.

The back seat offers excellent space for someone my size. At 182cm tall I had leagues of knee room and decent headroom, and of course all the soft trims continue. 

Bottle holders appear in the doors and drop-down centre armrest, and rear passengers score dual adjustable air vents and two USB-C power outlets. 

There are map pockets on the back of the front seats, and the higher-end Sports Luxury grade offers dual heated seats and a separate fixed sunroof panel for the enjoyment of rear passengers.

One interesting piece, however, is the high floor. Designed to facilitate the batteries, the high floor means you feel tilted back in the rear seats, like your knees are far off the ground.

The boot, meanwhile, is also surprisingly spacious given the raked rear window. At 522 litres it outranks most mid-size SUVs, and while it seems deeper than it is tall, it should be more than sufficient for the airport run or trips to the local Golf course.

An underfloor storage area is convenient for the stowage of your charging cables.

The RZ arrives in Australia in just one 450e all-wheel drive variant, with two trim levels to pick from. Either the entry-point Luxury grade ($123,000, before on-road costs), or the top-spec Sports Luxury ($135,000, before on-roads). 

It’s entering a hot market, which every luxury brand wants a slice of. Rivals include the outgoing Audi e-tron, ($138,323) which is set to be replaced by the presumably more expensive Q8 e-tron imminently, base BMW iX ($135,900), Genesis GV70 Electrified ($127,800) or the smaller GV60 ($107,700).

Soon it will also have to duke it out with the Polestar 3 which is higher performance, starting from $132,900, and there’s always the spectre of the Tesla Model Y, which is a comparative bargain at $98,415 for the go-fast Performance version.

In terms of premium-badged rivals, though, it’s at the lower end of the price-scale, following the Lexus model of providing relative value in its space.

The entry-level Luxury grade comes standard with 18-inch alloy wheels, LED headlights and tail-lights, a massive 14.0-inch multimedia touchscreen with Apple CarPlay and Android Auto connectivity, built-in sat-nav, connected services, wireless charging, a digital instrument cluster, synthetic leather interior trim, dual-zone climate control, push-start ignition with keyless entry, a 360-degree parking camera, a 10-speaker premium audio system, and the full safety suite. More on that later.

For the extra spend to get into the Sports Luxury grade, the wheels are upgraded to massive 20-inch units, then you can count on adaptive headlights, acoustic glass, contrast styling panels on the exterior (with a two-tone paint option), ‘ultrasuede’ interior trim with ‘Tsuyasumi’ ornamentation, interior LED ambient lighting, an electrochromatic sunroof, ventilated and heated front seats with infra-red ambient heating for front passengers, rear outboard heated seats, memory driver’s seat, a head-up display, touch-sensitive wheel controls, and a 13-speaker Mark Levinson audio system.

Some of these features are very cool. The sunroof and ultrasuede interior trim options with the detailed ornamentation, and even wacky carpet trim in the Sports Luxury grade, are enough to take you aback, helping this Lexus make its mark on the luxury mid-size EV market. 

Will it be enough to offset some notable omissions like the lack of vehicle-to-load systems or household power outlets on the interior?

This will depend on the buyer, but I think objectively this Lexus is playing into its existing loyal customer base more than it is the new-age tech savvy buyer.

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 RZ is only available with one powertrain choice, a dual-motor all-wheel drive set-up dubbed the 450e.

Unlike some systems, this dual-motor arrangement is far from symmetrical, with by far the majority of power sent to the front wheels.

Total system output is rated at 230kW/435Nm, consisting of 150kW/266Nm from the front, and just 80kW/169Nm from the rear.

Interestingly, this is significantly more punch than the Toyota bZ4X, further setting this Lexus apart.

The RZ uses a clever torque-vectoring system to make the most of this set-up when cornering, and debuts some interesting new tech like computer-balanced brakes to keep the car level under heavy deceleration as well as new adaptive pistons in the suspension to help the car adjust to different surfaces.

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.

Quoted range for the RZ is 470km, however this is to the more lenient NEDC testing cycle, as accepted by the Australian Design Rules. 

However, its real-world range is more like 400km, which is as it is more accurately measured to the WLTP standard.

The 71.4kWh battery pack is supported by a 150kW max DC charging speed, allowing a 10-80 per cent top-up in 30 minutes.

On a slower public AC charger, the RZ can pull a maximum speed of 11kW for charging in around six and a half hours, while single-phase charging, as you might get from a home wallbox system, at a rate of 7.0kW allows a charge time in around 10 hours.

Lexus throws in a public Type 2 charging cable, home wallbox installation, and a three-year Chargefox subscription (covering free fast charging) as part of an RZ purchase. Clever.

Officially the RZ consumes 18.7kWh/100km on the combined cycle according to the WLTP standard and I was surprised to find our car consumed 18.6kWh/100km during the test drive loop. 

For context, anything under 20kWh/100km is reasonably impressive in the premium EV space.

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).

Usually EVs, even premium ones, have a particular formula to the way they drive. 

Hefty, firm, and usually break-neck fast is the default position, with seemingly every manufacturer trying to remind buyers they too can be as fast as a Tesla.

However, the RZ breaks with the premium pack, offering a car which leans more into the luxury promise than maybe any other right now.

It’s a relatively serene space in the cabin, with notably limited wind or tyre noise, and a gentle steering tune which makes the car effortless to pivot into corners. 

This combines with the clever torque vectoring system, and lenient suspension to have the RZ simply wafting through corners.

The ride is interesting in that it is so far from the norm for the EV space. It is the opposite of firm and aggressive, with the car gently leaning into bends and barely feeling the texture of the road.

Small, rough bumps and high-frequency corrugations are dispatched with ease, the car simply floating over them, even when loaded up in corners, although, on the flip-side, longer undulations have it bouncing up and down a bit after-the-fact, perhaps a consequence of the doughy ride having to deal with the well-hidden weight of its batteries.

Despite efforts to deal with body-roll, there’s a notable amount, a consequence of the forgiving ride.

While these characteristics make the RZ a far more luxurious proposition on the road than many of its rivals, it is notable in how much it lacks a feel for the road. 

The steering is so electrically augmented it feels almost simulated, no matter which drive mode you select, and little of the road surface is communicated well to the driver. 

Even the brake pedal feels lifeless and distant, as it combines regenerative braking with the actual discs in a purely digitised progression.

The steering, acceleration and regenerative braking are all heavily altered by drive mode, with the car lacking a single-pedal drive setting, instead being fairly hands-off with the system. 

Some, looking for a particular EV drive experience, may be happy with this, others will appreciate how ‘normal’ the RZ feels in this department.

While the car feels disconnected in a sense, there’s no doubt the brakes work, the steering is effective, and it is deceptively quick. 

Its soft character might have you assuming it's slow, but a hot-hatch baiting 5.3 second 0-100km/h sprint time seems alarmingly achievable in the Sport mode.

One thing is for sure - everything described here is deliberate. Lexus has made a choice to go against the grain and do something different when it comes to the way this mid-size EV feels. 

To many existing Lexus loyalists, there will be a lot which is familiar, while providing a slice of the future, yet it might be far from the most engaging EV to drive. It certainly provides a gentler and more luxurious - if a little lifeless - alternative to the sporty status quo.

Safety comes standard on the Lexus RZ, with even the base Luxury trim-level scoring high-speed radar-based auto emergency braking (which detects vulnerable road users at night), lane keep assist (with lane departure warning), blind-spot monitoring (with rear cross-traffic alert), as well as driver attention alert, adaptive cruise control, and a tyre-pressure monitoring system as standard.

The only item reserved for the higher-grade Sports Luxury is the advanced adaptive high-beam suite.

The RZ also scores an impressive complement of 10 airbags, as well as the most recent crash structures in its fresh e-TNGA frame, however the EV mid-sizer is yet to be rated by either ANCAP or Euro NCAP.

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.

One of the key Lexus selling points is its ‘Encore’ ownership promise, which is at its best on its EV models.

For the RZ this includes a complementary 7.0kW home wallbox charger installation for those with garages, the inclusion of a wall socket and public Type 2 charging cables, a three-year Chargefox subscription keeping even your high-speed charging free for the duration.

The warranty is five years, unlimited kilometres, with roadside assist included.

Capped price servicing is available over five years, weighing in at $395 per 12 month or 15,000km interval, whichever comes first.

Lexus will also organise to pick up and drop off a loan vehicle at service time, while the high-voltage battery is covered by up to 10 years of warranty if the logbook is adhered to at an authorised Lexus workshop.

The brand also offers extra benefits through its ownership program, like deals at hotels and restaurants, as well as invites to events like track or golf days.

This is an impressive above-and-beyond suite of offerings befitting a premium brand, although it should be pointed out some premium EV rivals offer service intervals which are twice as long, and even free servicing for the entire warranty period.
