Mazda BT-50 vs Isuzu D-Max

What's the difference?

Key to the success of the BT-50 XS will be acceptance by fleet buyers. The vehicle, however, seems to be pretty well considered as far as that goes, although as with any stripped-down model, there are features that will be missed. Things like the manual air-conditioning probably won’t make much difference, but the lack of a tyre pressure monitoring system is a bigger issue for a working vehicle. Performance from the smaller engine is still well within acceptable parameters, but we reckon any buyer considering using much of the 3500kg touring capacity would be better off with the 3.0-litre engine offered in the rest of the BT-50 range.

The Mazda is not the best riding of its ilk, and there are competitors with bigger cabins, although, notably, at this point on the pricing ladder, these are often from China rather than Thailand where the Mazda is built. Ultimately it will come down to whether the smaller engine and reduced performance is an issue and also whether the money saved over the bigger-engined BT-50 is enough to justify that and the loss of some creature comforts. But since fleet managers are notoriously hard-nosed about this stuff, there’s a good chance to BT-50 XS will find a market.

The new engine makes the D-Max a much more likeable ute than it already was, which is high praise.

It’s smoother and quieter and makes for a more pleasant drive. The added efficiency is a bonus both for your wallet and Isuzu’s emissions credits.

The 3.0-litre engine will probably remain the favourite, but anyone who test drives a 2.2L might even be tempted to opt for the smaller unit. Isuzu sure hopes so.

Targeting tradies and fleet customers has meant Mazda has embraced the concept of factory accessories. Right now, there are options for tougher front bumpers, bull-bars, snorkels, drop-side trays, an awning, wheel-arch flares (for bigger, aftermarket wheel and tyre packages) driving lights, roof racks, canopies, tub-drawer systems and even a dual battery set-up. All these factory options carry the full Mazda warranty.

But Mazda has gone even further with accessory packs aimed directly at different fleet markets. For instance, there’s the Mine-Spec Pack which incorporates a park-brake alarm, high-mounted brake lights, a reversing buzzer, work-lights, LED rear lighting and pre-wired switches for auxiliary and beacon lighting.

Externally, Mazda's design brief for the BT-50 has clearly been to not frighten the horses. But it's better than that, because it has actually emerged as one of the better looking utes out there. In XS trim, even the steel wheels add a no-nonsense flavour to the overall effect. And where some of the competition appear to be trying very hard to ape the full-sized US-made pick-ups, the Mazda is its own thing.

Inside, the smaller info screens and simple layout in basic black tell the budget story. At the same time, there's a lot to like in terms of the clear, simple analogue gauges and the no-fuss controls including the conventional T-bar, park-brake and ignition key. There's a look and feel that also suggests this is a ute that should be able to take a few knocks in the course of earning a living.

The look of the D-Max depends on the grade you end up with, but the 2.2-litre SX and X-Rider variants down the lower end of the model-run are still pretty standard-looking utes. Inside and out.

You get fairly rugged styling that fits in for both work and play, and the interior is functional, if getting a little outdated. 

The black trim (and extra features) that comes with the LSM X-Rider as opposed to the SX is worth it if you’re keen to get a 2.2-litre-powered D-Max for the family rather than one for a fleet as it just elevates things slightly.

Inside, it also means nicer cloth, and not having the vinyl flooring looks a little less ‘farm ute’.

With a choice of cab-chassis of pick-up tub, not to mention the option of a single or dual-cab body in cab-chassis form, the XS allows for a fair bit of creativity in how it’s configured. The cab-chassis, for instance, will accept a conventional drop-side alloy tray or any number of service body configurations right up to camper bodies.

The stock tub on the pick-up version gets a drop-in liner but there’s no power outlet or light that some of the competition offer. The tie-down points are also a bit disappointing with two lower points in the rear of the tub and a pair of higher points in the front. Experience tells us that high-mounted tie-down points are vastly less practical than anchor points mounted close to the cargo floor.

The move to the larger engine has, however, increased the Mazda’s towing ability. From the previous version’s 3000kg towing limit, the new 2.2 can now legally tow 3500kg (with a braked trailer and approved tow-hitch). Payloads vary according to specification, but range from about 1000kg right up to 1379kg for the XS singe-cab-chassis.

The factory-option drop-side tray carries it’s load up high, but offers a flat floor with no wheel-arch intrusions. The standard tub is not as large in any direction, but does have a damped tailgate for safety (you can’t drop it) and convenience (the gas struts help raise it).

In the cabin, you get USB charging ports (two in the front, one in the rear seat) and there are central air-vents for the rear seat of dual-cab models. The dual-cab also has an under-seat storage area, two gloveboxes and a 60/40 split fold rear bench. The doors feature bottle holders and there’s a flip-down glasses compartment in the roof lining.

While the front seats are comfy enough for bigger drivers, the rear seat also goes against dual-cab tradition a little by having plenty of room in every direction, as well as a rational seat-back angle.

The D-Max remains straight-forward inside, given nothing has changed with the update aside from the 2.2-litre engine and the addition of stop-start - there’s a button for that now.

The interior and usability of the D-Max, especially in the lower-end variants where the 2.2L engine is available, is focused on the basics.

Tech remains at a relative entry point, where the 8.0-inch screen and its software feel outdated but do everything you need. Plus of course there’s the phone mirroring workaround.

The D-Max is comfortable and spacious enough, there’s also physical buttons for everything including media and climate settings, and adjustability in terms of the seating position means not needing to reach.

In dual-cab versions, there’s enough space for an adult to sit in the second row behind another adult, so the D-Max also holds its own as a family hauler. Tick.

Importantly, Isuzu is now able to claim a 3500kg braked towing capacity across the full D-Max range thanks to the new 2.2-litre engine.

Pricing is up across the board for D-Max (and its MU-X sibling) regardless of drivetrain, but we’ll stick to the 2.2-litre variants here to stay on track.

Most of the lower-level D-Max variants are $1500 more than the previous equivalent, and with the manual gearbox dropped, the cheapest grade is the 4x2 single-cab chassis SX with a 2.2L engine at $36,200 before on-roads.

You can get the SX in crew-cab with a chassis or ute back in either 4x2 or 4x4 with a 2.2L engine, which is also available in the LSM X-Rider 4x4. 

That one will set you back $59,500, which is still far from the most expensive D-Max around. That’s still the Blade, with a 3.0-litre engine and 4x4 only, but it’s now $80,900.

Back to the 2.2s, and the SX grade comes with the basics. Cloth upholstery, polyurethane steering wheel and gear selector, vinyl flooring and even halogen lights.

There’s basic air-conditioning, but it does have a HEPA filter, and rear vents for crew-cab models, plus there’s wireless Apple CarPlay and Android Auto, auto wipers, and USB-C power ports as well as a USB-A port.

The central multimedia touchscreen is 8.0 inches, but the driver display is a little 4.2-inch unit between physical dials.

Stepping up to the LSM X-Rider brings with it auto-levelling LED headlights and LED daytime running lights, black styling trim, nicer cloth trim upholstery and gloss black 17-inch alloy wheels.

The rest of the D-Max line-up is 3.0-litre-only, and remains as it was before.

The new engine capacity of 2.2 litres is up from the 1.9 of the previous XS version but still well short of the 3.0 litres of the more expensive BT-50 versions. And the specifications are pretty much exactly what you’d expect with the new 2.2 just about splitting the difference between the old 1.9 and the 3.0.

In this case, that equates to 120kW of power and 400Nm of torque, while the 1.9 was good for 110kW and 350Nm, and the 3.0 sports 140kW and 450Nm. So, yep, somewhere right about the middle. And that makes sense given the new 2.2 uses the basic mechanical architecture of the 1.9.

But the switch up to the new engine brings one very important change and that’s the adoption of an eight-speed automatic to replace the six-speed unit fitted to the previous XS and the other BT-50s. That has an obvious potential benefit for drivability, but also for fuel economy.

Mazda has also added stop-start tech to the XS in the name of efficiency. But, as we’ve found many times before, the fuel economy benefits seem restricted to the official test results rather than the real world where this technology serves to annoy many drivers more than anything else.

If you opt or the four-wheel-drive variants, you’ll get a rear diff lock but you miss out on an on-road 4x4 setting. Considering the 2.2-litre’s newfound towing capacity (the full 3500kg of the competition), that lack of a 4x4 Auto setting is a shame, but not an unexpected one at this price-point.

The new 2.2-litre turbo-diesel four-cylinder comes with 120kW and 400Nm, that’s 10kW and 50Nm more than before. Isuzu also says there’s 60 per cent more torque ready from near-idle at 1000rpm.

An eight-speed auto replaces the six-speed, but the brand has also culled the manual options that remained in the line-up.

As ever, that sends power and torque to a part-time 4WD system capable of 2H, 4H and 4L with a rear diff-lock.

While one of the expected benefits of the 2.2-litre engine compared with the three-litre unit is a reduction in fuel consumption, the new 2.2 engine goes one big step further by actually being more frugal than the 1.9-litre engine it replaces. Well, in terms of the official government test, anyway.

The single cab-chassis model in new 2.2-litre, two-wheel-drive form posted a combined (urban-highway) fuel number of a creditable 6.9 litres per 100km. Compared with the mechanically similar 1.9 single cab-chassis, that’s a saving of 0.1 litres per kilometre, and a corresponding drop in tailpipe carbon emissions of 1 gram per kilometre.

To be honest, this small improvement is probably largely due to the stop-start system now fitted, which many drivers will turn off at the first opportunity. Even so, the new eight-speed transmission must also be playing a part, so let’s call the old and new engines line-ball in the real world.

The rest of the XS line-up scored official figures of 6.3 litres per 100km for the double-cab pick-up 4x2, 7.1 litres for the double cab-chassis 4x4 and 6.6 litres per 100km for the dual-cab pick-up 4x4.

With the BT-50’s standard 76-litre fuel tank, the theoretical range is more than 1000km. In reality, that’s going to be closer to 800km.

The BT-50 engines do not require AdBlue additive to reduce exhaust emissions.

The biggest advantage for the new drivetrain from Isuzu’s perspective is that it’s more fuel efficient.

The old engine’s 6.9 litres per 100km become 6.6L/100km in the new engine, in part thanks to a new stop-start system. That system is also now on the 3.0-litre engine, where 8.0L per 100km drops to 7.1L.

With its 76L diesel tank capacity, the D-Max should theoretically be able to travel more than 1000km on a single fill, although that comes down to a lot of variables - that 6.6L figure was achieved in almost lab-like conditions.

Striking the right balance between ride comfort and load-lugging capacity has always been the big trick with utes in general. The fact is, there’s probably no ideal setting, especially considering the range of payloads a ute can be expected to carry on any particular day. In the BT-50’s case, Mazda has opted to go for a stiffer suspension tune. That means it can technically tow and haul with the best of them, but it also dictates that ride quality is far from what you’d call plush, even in this market segment.

The ute handles bumps best when the undulations don’t come too hot and fast. But strike a patch of high-frequency lumps and bumps and the suspension, particularly at the rear, starts to pogo about with a corresponding decline in ride control. The steering, too, seems to lack a little feel and is relatively slow-geared (although that has its benefits off-road).

The engine certainly does the job in isolation, but it’s likely to struggle a little with the full three-and-a-half tonnes on the hitch. It’s pretty noisy, too, and definitely sounds like a diesel, unlike some modern diesel designs that are more refined. There’s also a sense that Mazda has ditched some of the sound deadening of other BT-50 models, as the engine is certainly heard and felt. The optional snorkel moves the induction noise right into the driver’s window when it’s open, too.

But the new eight-speed automatic transmission is a beauty. Upshifts are crisp and smooth and even the downshifts as you approach a full stop are measured and calibrated to never intrude. And it’s nice to see a conventional T-bar shifter with no separate park button or non-intuitive movements required.

We didn’t get a chance to try the BT-50’s off-road chops, but past experience tells us that the Mazda will be pretty good. As with many four-wheel-drive utes, the limiting factor will be the standard tyres fitted at the factory.

Let’s start with the most important part of the updated D-Max. The new 2.2L is smooth. 

It feels so much more refined physically, but it's also quieter. Paired with the new eight speed, it makes the D-Max a much more likeable ute than it was with the rattly 1.9L.

At the launch, Isuzu had a bunch of MU-Xs to drive (keep an eye on a review coming soon), and the new drivetrain actually suits that big family SUV down to a tee.

The power and efficiency changes are second to how much it changes the characteristics of the thing.

If anything, the D-Max sits in a slightly higher gear than necessary, probably to try and eke as much out of the diesel dual-cab as possible in terms of fuel efficiency, but put your foot down and a more appropriate gear is close-by, and without much fuss.

There's also a relatively good stop-start system. It's not seamless but it's better than some. You take your foot off the brake and the engine rattles back to life, rather than waiting for you to put your foot back down.

The rest of the D-Max’s behaviour is pretty standard ute stuff, as it was before.

The steering is on the light side, but accurate enough even though it has a slightly doughy spot dead-straight. It’s not anything you wouldn’t expect from a ute.

Similarly, the brakes are a bit spongy but predictable, and once you’re used to where the ‘bite’ point is it’s easy to live with.

The suspension is a bit busy, but easy to keep on top of and doesn’t jostle you around. 

Isuzu has done well to include pretty much the full range of safety features across all its variants, with the SX only missing out on rear parking sensors - it still has a camera though, obviously.

Key features like rear cross-traffic alert with braking and adaptive cruise control are standard, plus the D-Max achieved a five star crash safety rating from ANCAP, even though that was under slightly easier testing back in 2020.

The biggest (but only) gripe on-test with the D-Max’s safety gear was its lane-keep during adaptive cruise. There seemed to be a need for the ute to sit close to either the centre line or shoulder during cornering, which led to some discomfort on fast country roads.

Mazda’s standard five-year/unlimited-kilometre warranty applies to the BT-50 range, and includes the first five years of roadside assistance, too.

Service intervals are every 12 months or 15,000km, whichever comes first. Capped-price servicing is available with the first five years of servicing costing $2188 on 4x2 versions and $2302 for 4x4 variants.

It’s worth mentioning that the BT-50’s new engine is Euro 5 compliant but doesn’t require AdBlue, reducing running costs.

Isuzu’s six-year/150,000km warranty covers the D-Max, which could do without the limited distance, especially for a workhorse.

There’s also five years of flat-rate servicing every 12 months or 15,000km, costing $469 each time.

That’s gone up about $20 per visit since the update, with total cost over the five years at $2345.

There are 164 Isuzu dealers across the country, so finding somewhere to service shouldn’t be a challenge.
