Mazda BT-50 vs Isuzu D-Max

What's the difference?

The XTR LE adds polish to the BT-50 line-up, in more ways than just its silver metallic paint and highly buffed accessories. It also has exceptional fuel economy and is equally competent as a suburban daily driver, tradie’s workhorse and weekend escape machine, with robust load-carrying and towing ability. For those wanting an upmarket version of the popular XTR, the LE has plenty of appeal. 

The new D-Max hasn’t been majorly overhauled and instead bundles together a whole bunch of small but important changes, all of which have been designed to keep it fresh in the face of its competition, like the Triton, Ranger and HiLux.

Has it done enough? Only time will tell. But there’s little doubt that these updates only improve the D-Max formula.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The XTR is a happy medium between the work-focused XS and XT models and higher-grade GT, SP and top-shelf Thunder offerings, so the additional equipment that comes with the LE enhances the appeal of this popular model grade.

The bull-bar integrates with the BT-50’s safety systems ensuring crumple zones, airbags and driver assistance systems are not compromised. 

This bull-bar design also ensures no adverse effect on engine and transmission cooling and its single hoop is ideal for mounting extra driving lights.

The load tub-mounted sports-bar includes an integrated brake light for enhanced safety, while the heavy-duty tub-liner protects against dents and scratches.

The XTR interior has a quality look and feel with a tasteful blend of piano black and satin chrome highlights on the dashboard and door linings, contrasting fabric seat trim, exposed stitching along numerous seams and adjustable centre console a/c vents for rear seat passengers.

Driver and front passenger get comfortable bucket seats and the rear seating is also accommodating, with ample head and kneeroom even for tall adults. 

However, shoulder room is tight when travelling three-abreast, so like most dual cabs of this size it’s most comfortable as a four-seater.

There are some big-ish changes for this new-look D-Max, but how many of them you get depends on which of the six trim levels you’re shopping for.

Spring for one near the top of the family tree, and you’ll get all of the updates, which include new-look headlights that are LED with LED DRLs (but halogens on the SX), and a new-look front-end and grille. At the rear, there are new LED rear light clusters.

It doesn’t look a million miles away from the current D-Max, to be honest, but it does look a little newer, and a little fresher, which is important in the battle of the inches that is the new-ute market.

Inside, the brand describes the cabin as a mix of utility and comfort, and that’s feels pretty accurate from the driver’s seat.

The tech is new, with the 8.0- or 9.0-inch central screen joined by USB connection points, and there’s a new Digital Driver Display screen in the mix, along with new seat materials and trims, too.

But back to that that mix of utility and comfort. I’m not sure Isuzu has gotten the mix exactly right. There are plenty of soft-touch materials in the higher-trim levels, just not always where I want them to be.

I don’t know about you, but I like to have my elbow up when driving, and that plastic is still scratchy and hard, as is the place where my knee touches the centre console.

That said, it’s largely comfortable, definitely functional, and it serves up pretty much exactly what you might expect.

The addition of the LE’s accessories adds 81kg to the XTR’s kerb weight, which increases from 2030kg to 2111kg. As a result, the payload rating must drop by the same amount, from 1070kg to 989kg, to avoid exceeding the vehicle’s 3100kg GVM. 

The LE retains the XTR’s class-benchmark 3500kg braked tow rating but to keep below its 5950kg GCM (how much it can legally carry and tow at the same time) while doing that, the payload limit would have to be reduced by a sizeable 650kg. 

Alternatively, you could lower the trailer weight limit by the same amount (to 2850kg) and keep the full payload, which is not only more practical but also safer for towing.

The lined load tub is 1571mm long, 1530mm wide and 490mm deep with 1120mm between the wheel housings, which means it can’t carry a standard Aussie pallet but will take a Euro. There are four sturdy load anchorage points.

Cabin storage includes a large-bottle holder and bin in the base of each front door. The dash offers a closable compartment to the right of the driver’s knee for small items, upper and lower glove boxes and an overhead glasses holder. 

The centre console has an open tray at the front, dual small-bottle/cup-holders in the centre and a small box at the rear with a contoured lid that doubles as a driver’s elbow rest.

Rear passengers get a large-bottle holder and small bin in each door, plus pockets on the front seat backrests and two pop-out cup holders in the fold-down centre armrest. So, in total that’s four large-bottle holders and six small-bottle/cupholders. 

The 60/40-split rear seat base-cushions can also swing up and be stored vertically if more internal load space is needed. This also reveals two underfloor compartments with lids for keeping valuables out of sight, so there are plenty of places to store things.

Isuzu has taken to calling the D-Max one of Australia’s most capable utes out of the box.

That includes up to 240mm in ground clearance, 800mm in wading depth, and a towing maximum of 3.5 tonnes for the bigger diesel engine, dropping to three tonnes with the 1.9-litre powerplant fitted. Payload is up to 1405kg, too, but to get you need the SX with Cab Chassis. It’s more like 1045kg for most dual-cab ute trims.

Also new for this update is the addition of Rough Terrain Mode — a technology borrowed from the MU-X, then improved to pair with the D-Max’s mechanical off-road features.

In short, the tech taps into the traction-control systems to detect wheel slip, and can then brake individual wheels and send torque to where it is needed to smooth your progress. In the D-Max, it works with the rear diff-lock, too.

The back seat of the D-Max shows why vehicles in this category are now doubling as family vehicles. Behind my own 175cm driving position there was enough knee and headroom to get comfortable, and I’m confident you could fit three across the back row pretty easily, too.

There are some creature comforts, including a USB-C charging point (trim dependent) as well as air vents, but no temp controls, and even a little coat hook as well, but it’s not swimming with niceties.

Ute ranges being the insanely complex webs they are, you’ll be unsurprised to hear there are lots of options here. In fact, there are some 25 combinations, spanning six grades, two engines, two gearboxes, a choice of two- or four-wheel drive and four body styles.

The price range is vast, too, now starting at $32,700 for the SX Single Cab Chassis with a 1.9-litre turbo-diesel and two-wheel drive, and climbing to a $70,500 MSRP for the X-Terrain Crew Cab with a 3.0-litre turbo-diesel and four-wheel drive.

To keep this brief, we'll focus on the Crew Cab Ute, which is yours in SX, LS-U, LS-U+, LS-M, X-Rider and X-Terrain guises, but we will also post a full price list below so you can choose your own adventure.

The SX range is now $500 more expensive across the board, and it starts at $42,700 with a 1.9-litre engine and two-wheel drive, or $50,700 for four-wheel drive. If you want the bigger 3.0-litre powerplant, it’s $44,700 for the 2WD, or $52,700 for the 4x4.

Then it’s the LS-U, which is big-engine only, and is $54.5k (which is up by $1500, by the way) for the 4x2, and $62.5k (again up $1.5k) for the 4x4. There’s also a LS-U+, which is $65,500 in 4x4.

Next is the LS-M, which is $55,800 (up $500), before the new-for-2024 X-Rider jumps in at $59,500. Both are four-wheel drive only and feature only the big engine.

Finally, there’s the flagship X-Terrain — big engine only, and four-wheel drive as standard — which is $70,500 (up a sizeable $3k), but which is also just $67,990 drive-away, at least for now.

The entry-level SX gets a vinyl floor, cloth seats, powered windows and mirrors, and air-conditioning with rear vents. Tech is handled by a new 8.0-inch central touchscreen with wireless Apple CarPlay and Android Auto, pairing with four speakers, while an also-new 4.2-inch screen sits in the driver’s binnacle. You also get 17-inch steel wheels, automatic wipers and halogen headlights.

Stepping up to LS-M trim gets you new and softer rear suspension, a higher-grade cloth interior treatment, bi-LED headlights and DRLs, 17-inch alloy wheels and body-coloured mirrors, door handles and tailgate handle. If you can spring for this trim, it feels like the sweet spot of the lower-range models.

Next there’s the new X-Rider, which was once was a special edition but now rejoins as a permanent member of the family. It’s all about upping the street credibility, so there’s black gloss on the grille and a black underbody spoiler, as well as black on the rear step bar, the mirrors, door handles and tailgate handle, the B-pillars, the sports bar and on the soft tonneau cover. There are also black 17-inch alloy wheels and dark grey side steps.

Next up is the LS-U, which ups the cabin tech with a new 9.0-inch central screen, but with tactile dials for volume — fixing what was apparently a big complaint about the outgoing D-Max – as well as a new 7.0-inch Driver Display. There’s also keyless entry and push-button start, including a new welcome light that illuminates the interior when you approach, dual-zone climate control and a nicer interior treatment. Outside, there’s a tub liner, silver side steps, chrome on the handles and mirrors and 18-inch alloys.

The LS-U+ then adds leather seats which are heated in the front and eight-way power-adjustable for the driver, and four-way power-adjustable for the front passenger.

Finally, the flagship X-Terrain gets red stitching across its leather interior, remote engine start, a rolling tonneau cover, a unique sport bar, dark grey side steps, mirrors, handles and roof rails, and 18-inch matte-grey alloys wheels.

2024 Isuzu D-MAX Pricing (RRP before on-road costs unless specified)

The Isuzu-sourced 3.0-litre four-cylinder intercooled turbo-diesel is a refined and proven performer, producing 140kW at 3600rpm and 450Nm of torque which peaks across a 1000rpm-wide band between 1600-2600rpm.

This is paired with a refined Aisin six-speed torque converter automatic, offering fast but smooth shifting and intelligent protocols that prompt automatic downshifting to assist with engine-braking on steep descents. 

It also has sequential manual-shifting plus overdrive on the top two ratios to optimise fuel economy during highway driving.

The part-time, dual-range 4x4 transmission has 2.482:1 low-range reduction and a switchable locking rear diff.

The D-Max’s powertrains for 2024 remain unchanged, with the choice of a 1.9-litre turbo-diesel four-cylinder engine good for 110kW and 350Nm, or a 3.0-litre unit producing 140kW and 450Nm. They are paired with either a six-speed manual or six-speed automatic, and two- or four-wheel drive, depending on the model.

Mazda claims official combined cycle consumption of 8.0L/100km which was close to the 8.4 showing on the dash display at the end of our 276km test. 

Both were close to our own figure of 8.7 calculated from fuel bowser and trip meter readings, which is outstanding single-digit economy for a 4x4 dual-cab ute weighing more than two tonnes. 

So, based on our numbers, you could expect an excellent real-world driving range of around 870km from its 76-litre tank.

Isuzu reckons you’ll see around 8.0L/100km on the combined cycle with the bigger engine, with fuel use dropping to 6.9L/100km with the 1.9-litre unit fitted.

The 76-litre tank is the same for both engines, meaning a theoretical range of 950km or 1100km.

There are big handles on the front windscreen pillars to assist entry and it’s easy to find a comfortable driving position given the spacious cabin, height/reach adjustable and leather-wrapped steering wheel, big left footrest and adequate adjustment in the driver's seat which includes variable lumbar support. However, some rake adjustment in the seat base would be welcome.

It has solid build quality with low engine, tyre and wind noise. All-round vision is good, enhanced by useful driver aids like blind-spot monitoring and a reversing camera. 

Our only criticisms are an annoying glitch in the design of the driver’s sun-visor, which clips the edge of the rear-view mirror enough to dislodge it each time the visor is swung down. 

And there are no rotary dials on the media screen for quick and easy adjustment of audio settings. Buttons are not as user-friendly.

Handling is sure-footed for a high-riding 4x4, the braking is reassuringly strong (particularly under load) and steering feel is amongst the best in class. 

The engine has good response and never feels sluggish in city and suburban driving thanks to its broad spread of torque, enhanced by an automatic transmission that generally gets the best out of this engine without the need to manual-shift.

It’s also a comfortable and economical highway cruiser. With the overdriven top gear and full torque converter lock-up, it can consume long distances with minimal effort as the engine requires only 1600rpm to maintain 110km/h. The adaptive cruise control works well.

We didn’t forklift a load into the LE as we have already tested the standard XTR on which it’s based with a 950kg payload, which was only 40kg under the LE’s maximum rating. 

On that occasion the leaf-spring rear suspension compressed 75mm, but there was still more than 30mm of stationary bump-stop clearance remaining. That ensured it never bottomed-out, floating over large bumps and through dips with ease.

We have also towed a 2.5-tonne dual-axle caravan with an XTR during which it also excelled, so in LE form it’s not only a comfortable daily driver but a competent load-hauler, too.

Remember, it’s evolution over revolution for the 2024 Isuzu D-Max, so don’t expect the drive experience to be dramatically different. 

Instead, the brand says it has focused on fixing some of the complaints surrounding the outgoing model, something Isuzu is pretty open about.

It says they’ve taken feedback from the media, from their customers, and from their big fleet users, and they’ve fed it up their Japanese HQ. And the result of all that is this 2024 update.

Apparently one of the biggest complaints focused on the infotainment screen having no physical buttons, but the new one changes that with its wireless Apple CarPlay and twin USB connection points joined by a physical volume dial. I know that feels a little like you’ve taken a step backwards through time, but when something works, it works.

The’ve also made some key, and worthy, changes to the safety systems, but we will get to those in a moment.

The reality is — and I don’t mean this in an insulting way — that the new D-Max largely drives much like you might expect a top-selling diesel dual-cab to drive.

The torque on offer from both engines, but especially the bigger one, is plentiful, even if the noise of the diesel is an ever-present passenger when you put your foot down, and there is that inescapable truck-like feeling from behind the wheel.

There are some elements that set it apart, though. The steering is smooth and responsive, as is the quick-witted automatic gearbox, and despite us tipping into corners a little faster than we would on our daily commute, there wasn’t much in the way of side-to-side body roll, and no complaints from the rubber.

That might sound like I’m damning the D-Max with faint praise, but that’s not the intention. It’s a comfortable, capable, practical workhorse, and that’s ticking plenty of ute boxes, right?

The bigger-engined D-Max remains a towing powerhouse, too. We pulled some serious weight, and 3.0-litre turbo-diesel made pretty light work of it, with ample torque on offer to keep things moving.

It wouldn’t be the launch of an updated diesel dual-cab without a tour across a tailored off-road course, and Isuzu delivered, specifically to plug the merits of its new Rough Terrain Mode.

Tested back-to-back with the system switched on and off, there does seem to be less slip from the wheels when traversing bumpy, tyre-torturing articulations, with the D-Max just gripping and going. It’s another off-road tick for a ute already very good in the rough stuff.

Full credit to Isuzu for equipping the entire D-Max range with the best of its safety equipment, much of which has been overhauled for this generation.

That starts with a new-generation camera that scans the road for cars, pedestrians and cyclists with greater clarity. It also includes a charging plug for an aftermarket dash-cam.

There’s now updated Lane Keep Assist, better programmed to centre in the lane rather than bouncing from edge to edge, bumper bowling style. There’s Rear Cross-Traffic Alert and Brake and Adaptive Cruise Control, too.

That fact that it’s all standard from the entry-level SX is fantastic, and the D-Max range copped the full five-star ANCAP rating when tested in 2020.

The BT-50 is covered by a five-year/unlimited km warranty.

Scheduled servicing is every 15,000km or 12 months, whichever occurs first. 

Minimum combined cost is $2404 for the first five scheduled services, for an annual average of $481.

The D-Max is covered by Isuzu’s six-year, 150,000km warranty, and we like the years, but less so the kilometre limits.

There’s five years of capped-price servicing, too. You’ll be visiting the service centre every 12 months or 15,000kms, and each visit will cost you $449 for the first five years, or $2245 in total.
