Mazda BT-50 vs Toyota HiAce

What's the difference?

The MY25 Mazda BT-50 benefits from its robust Isuzu underpinnings to excel in this dual cab-chassis configuration, particularly with Mazda’s premium heavy-duty aluminium tray as fitted to our test vehicle. Fact is, apart from the big drop in payload required to tow 3500kg (but it’s not alone there) it’s hard to find any major flaws. Overall, it’s an excellent workhorse that would be well suited to a multitude of tradie tasks. 

When you consider its competitive pricing (particularly for fleets), resolute resale value, robust construction, rock-solid reliability, excellent load-hauling ability, five-star safety and all-round practicality, it’s not hard to understand why the HiAce is such a popular workhorse. It’s not perfect, like any van, but when performing its intended role it’s very good.

It must be said that Mazda’s stylists did a commendable job with the third-gen BT-50 when it launched in 2020. Five years later it still looks fresh and we’re yet to find anyone who doesn't like its styling, which is in stark contrast to its polarising predecessor.

Its exterior sculpting embodies Mazda’s design language to maintain a strong family resemblance to the popular CX line of SUVs, yet does not detract from the tough and purposeful appearance expected of a 4x4 ute.

The MY25 facelift includes a newly designed front bumper, radiator grille and unique LED headlights. At the rear, pick-up models incorporate what Mazda describes as a ‘mountain-inspired ridged design’ along the bottom edge of the tailgate, along with new LED tail-lights and a larger Mazda logo.

Apart from the mountain-inspired ridged design, also evident on the glove box lid, the latest XTR interior is largely unchanged, blending different shades of grey with satin chrome highlights on the dashboard and door linings, contrasting fabric seat trim, exposed stitching on seams and adjustable centre console air conditioning vents for rear seat passengers.

Toyota’s unwavering adherence to rear-wheel drive ensures the HiAce has an inherent traction advantage over its predominantly front-wheel-drive rivals, particularly when hauling heavy payloads on low-grip surfaces.

Rear-wheel drive also ensures the front wheels can be turned sharply enough for its 3210mm wheelbase to deliver an impressively tight 11.0-metre turning circle. And its 1990mm height also allows access to underground loading docks and multi-storey car parks.

The chassis design is simple and robust with MacPherson strut front suspension, a leaf-spring live rear axle, variable-ratio rack and pinion steering and (on automatic variants) four-wheel disc brakes.

There’s no mesh-type cargo barrier or solid bulkhead between the cargo bay and cabin (but both are also available as genuine accessories) and the black door-handles and unpainted black plastic front and rear bumpers are designed to best withstand the wear and tear often evident in these areas on hard-working vans.

The two-tone dash layout is neat and functional, with clear analogue instrumentation and dash controls (mostly physical dials and buttons) that are easy to reach and operate. And it sticks with a good old lever-type manual handbrake instead of an electric one. All are chosen for their rugged simplicity.

The only useful item missing is a fold-down inboard armrest for the driver’s seat, offered by numerous rivals to reduce neck and shoulder strain during long days behind the wheel.

Our test vehicle’s 1910kg kerb weight and 3100kg GVM results in a meaty 1190kg payload rating. However, that drops to 891kg after you deduct the combined weight of the premium heavy-duty aluminium tray (243kg), nudge bar (9.0kg) and towing kit (47kg).

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer but with its 6000kg GCM (or how much it can legally carry and tow at the same time), towing that weight would require a substantial 590kg reduction in payload to avoid exceeding the GCM.

Even though few (if any) BT-50 owners would need to tow 3500kg, it’s important to be aware of these numbers if the need arose, to ensure the combined weight of your vehicle and trailer does not exceed the legal limit.

The premium heavy-duty aluminium tray from Mazda’s genuine accessories range is a nice bit of kit with its Mazda-branded tailgate decals and mudguards.

The tray is almost square with internal dimensions of 1800mm length and 1777mm width. And it has numerous internal load-anchorage points, external rope-rails and a sturdy mesh-style rear window protector, plus removable ‘quick-lock’ ladder racks with fold-down load retainers up top.

There’s also a 1500mm-long underbody drawer with adjustable internal dividers and a four-stage incremental locking system. An HDP (High Density Polyethylene) 25-litre water tank complete with tap and handwash bottle-holder resides under the right side of the tray, with a sizeable and lockable HDP toolbox under the left side.

The driver and front passenger have comfortable bucket seats and the rear bench is also accommodating, with ample head and kneeroom even for tall people.

However, shoulder room would be tight for three big tradies, so like most dual cabs short of a full-size US pick-up it’s tolerable for short trips as a five-seater but works best as a four-seater for longer drives.

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

The centre console has an open tray at the front, dual small-bottle/cupholders 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 storage pockets on the front seat backrests and a pair of pop-out cupholders in the fold-down centre armrest.

The 60/40-split rear bench seat’s 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.

Our barn-door-equipped test vehicle has a hefty 2245kg kerb weight and 3300kg GVM, which results in a genuine one-tonne-plus payload rating of 1055kg. Up to 120kg of that weight can be carried on Toyota’s triple roof-rack set.

It’s also rated to tow up to 1500kg of braked trailer, which is less than some rivals but in reality should adequately cover most towing requirements of van operators.

And with its 4800kg GCM rating (or how much weight it can legally carry and tow at the same time), that means it can carry its maximum payload while towing its maximum trailer weight. So, that’s a combined total of more than 2.5 tonnes of cargo-carrying ability, which would comfortably meet or exceed most job requirements.

The generously-sized cargo bay, which offers an impressive 6.2 cubic metres of load volume, is accessed from either side through sliding doors with large 1010mm openings, or from the rear through the optional barn doors which can be opened to 180 degrees (with special lower hinges to hold them there) allowing easy access for forklifts.

The cargo bay is 2530mm long, 1760mm wide and 1340mm high and with 1268mm between the rear wheel housings it can swallow up to two standard Aussie pallets or up to three Euro pallets, held in place by a choice of six load-anchorage points.

There’s plenty of internal lighting, the walls and doors are lined to mid-height and the roof features a full-length internal lining, which is unusual for vans and we suspect contributes to suppression of tyre noise emanating from the rear wheel housings.

Cabin storage includes a large bottle holder and bin in the base of each front door, small-bottle/cupholders on either side of the dash and in the centre, plus a single glove box. The well-designed centre console offers another two bottle holders plus large internal storage, which is capped by a hinged lid that multi-tasks as a shallow storage tray and handy work desk.

Our test vehicle is equipped with Toyota’s ubiquitous 2.8-litre four-cylinder turbo-diesel shared by all models in the HiAce range. However, ours is equipped with the optional six-speed automatic and rear barn doors which raises the list price to $51,636.

Even so, that’s still within the ballpark of its closest rivals including the LDV G10+ Barn Door ($40,063), Hyundai Staria Load Barn Door ($46,740), and Ford’s new Transit Trend LWB Barn Door ($57,590).

Our example is also equipped with a solid-walled left-side sliding door (in preference to the standard offering with window), which HiAce buyers can specify at no extra cost when ordering.

The two-seater HiAce comes standard with 'French Vanilla' paint and 16-inch steel wheels with replaceable plastic covers, 215/70R16 tyres and a full-size spare, but there’s no protective load-floor liner for the cargo bay (a Toyota genuine accessory is available).

There’s also halogen headlights and DRLs (no fancy LEDs here, folks) and the neat two-tone cabin has a tilt/reach adjustable leather-accented steering wheel, power-adjustable lumbar support on the driver’s seat, one USB port and two 12-volt cabin sockets, plus a large centre console that offers numerous storage options.

The driver also gets a 4.2-inch driver’s info display and there’s an 8.0-inch touchscreen (plus steering wheel switches) to control the two-speaker infotainment system, which offers multiple connectivity including Apple CarPlay/Android Auto, Bluetooth, digital radio and more.

The BT-50’s drivetrain, shared with its D-Max donor, comprises Isuzu’s proven Euro 5-compliant 3.0-litre, four-cylinder, turbo-diesel that produces 140kW of power at 3600rpm and 450Nm of torque between 1600-2600rpm.

This is paired with an Aisin-sourced six-speed torque converter automatic featuring ‘intelligent’ protocols that prompt downshifting to assist with engine-braking on steep descents (great when towing) and overdrive on the top two ratios optimises fuel economy during highway driving.

It also offers the choice of sequential manual-shifting, which can be handy when hauling and/or towing heavy loads particularly in hilly terrain.

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

Toyota’s well-proven 1GD-FTV 2.8 litre four-cylinder turbo-diesel, which also powers Toyota’s HiLux, Fortuna and Prado model lines, produces 130kW at 3400rpm and (in auto models like ours) 450Nm of torque between 1600-2400rpm. Its Euro 5 emissions compliance doesn’t require AdBlue, which minimises maintenance and running costs.

The refined and smooth-shifting six-speed torque converter automatic offers the choice of sequential manual shifting if required. Fuel efficiency is also optimised with full torque converter lock-up on fourth, fifth and sixth gears, along with overdrive on fifth and sixth being ideal for highway driving. The inherent traction advantage of rear-wheel drive is enhanced by an electronically controlled automatic limited-slip diff.

Mazda claims an official combined cycle (urban/extra-urban) average of 8.0L/100km and the dash display was showing 10.2 at the completion of our 369km test, which comprised a mix of city, suburban and highway driving of which about one third was hauling a near-maximum payload.

Our own figure, calculated from fuel bowser and tripmeter readings, was slightly higher again at 10.6L/100km but still within the usual 2.0-3.0L/100km discrepancy between official and real-world figures and not bad for a two-tonne-plus 4x4 ute.

So, based on our figure, you could expect a realistic driving range of around 700km from its 76-litre tank.

Toyota claims combined average consumption of 7.9L/100km for our test vehicle, but the dash readout was showing 11.0L/100km when we stopped to refuel after 270km of testing.

This was conducted with the engine’s auto start/stop function switched off and comprised a mix of city, suburban and highway driving, of which about one third was hauling a near-maximum payload.

Our own figure, calculated from actual fuel bowser and tripmeter readings, was higher again at 11.8, which still isn’t bad for a vehicle with a kerb weight exceeding 2.2 tonnes driven mostly in busy urban traffic and hauling almost one tonne during our test. So, based on our ‘real-world’ consumption figures, you could expect a driving range of around 600km from its 70-litre tank.

The cabin is spacious and, with side-steps plus large handles on the front windscreen pillars, it’s easy to climb aboard and find a comfortable driving position.

All-around vision is good and active driver aids like blind-spot monitoring, rear cross-traffic alert and reversing camera instil confidence, particularly when hauling taller loads that block rear vision through the central mirror.

The engine is responsive in city and suburban use, thanks largely to its broad spread of torque across a 1000rpm-wide band from 1600-2600rpm that showcases its useful flexibility. The six-speed automatic has well-spaced ratios and shift calibrations that feel like they get the best out of this engine, either unladen or when hauling heavy loads.

It feels well-planted on the road and displays sure-footed handling if driven at appropriate speeds for a high-riding 4x4 ute, combined with excellent steering feel and responsive braking.

The unladen ride is firm, as you’d expect given the heavy-duty rear suspension unique to cab-chassis models, but the combined sprung weight of the tray and tow bar ensure it’s not too harsh.

To test its payload rating we strapped 830kg onto the load tray, which with driver and half a tank of diesel was a snip under its GVM limit. Even so, the rear leaf-springs only compressing 40mm under this loading, which left more than 40mm of bump-stop clearance that ensured no bottoming-out on our test route.

It hauled this big load with competence and a smoother ride quality, given the large increase in sprung weight allowed the heavy-duty rear suspension to do what it’s primarily designed to do.

There was also minimal effect on steering and braking response and the engine’s ample torque was not phased by this payload, particularly on our 13 per cent gradient, 2.0km-long set climb at 60km/h.

Engine-braking on the way down was also robust, highlighting the advantage of larger displacement engines (3.0-litres-plus) on overrun when restraining heavy loads on steep descents.

It also has low engine, tyre and wind noise at highway speeds, where the engine requires less than 2000rpm to maintain 110km/h thanks to its overdriven top gear with full torque converter lock-up.

This ensures the BT-50 is a comfortable and economical highway cruiser, with average fuel consumption that quickly drops into single figures on long hauls.

It’s easy for drivers of most shapes and sizes to find a comfortable driving position in the spacious cabin, given its height/reach adjustable steering wheel, large left footrest and supportive seating with power-adjustable lumbar support.

Although there’s a huge blind spot over the driver’s left shoulder created by the solid walls of the cargo bay, active driver aids including blind-spot monitoring, rear cross-traffic alert and rear-view camera minimise the potential hazards of changing lanes and reversing out of driveways into busy traffic.

Braking is reassuringly strong and the steering is responsive, with easy manoeuvrability thanks to the conspicuously tight turning circle and lightness of the variable-ratio steering at parking speeds.

The ride quality is reasonably supple when unladen or lightly loaded and, for a van without a bulkhead between the cabin and cargo bay, has comparatively low internal noise levels at speeds up to 80km/h.

The 2.8-litre turbo-diesel, with its sizeable 450Nm of torque, has strong low-rpm response and displays good flexibility in city and suburban driving.

Its performance is optimised by the smooth-shifting six-speed auto, which also delivers fuel-efficient highway travel that requires less than 2000rpm to maintain 110km/h. The sequential manual-shifting function can be handy in certain situations, like carrying/towing heavy loads in hilly terrain.

To test its GVM rating we forklifted 890kg into the cargo bay, which combined with the driver equalled a total payload of 990kg that was only 65kg shy of its 1055kg limit.

The stout rear leaf-springs only compressed about 30mm under this loading, which left more than 60mm of static bump-stop clearance that was more than enough to ensure there was no bottoming-out on our test route.

The turbo-diesel’s ample torque made light work of hauling this payload in city, suburban and highway driving. It was also particularly strong in the hills, where it easily conquered our 13 per cent gradient, 2.0km-long set climb in third gear.

Engine braking on the way down, in a manually selected second gear, wasn’t as strong but far from disgraced given the near one-tonne payload it was trying to restrain. Even so, its four-wheel disc brakes were more than capable of keeping speeds in check.

Our only criticism is the high internal noise levels at highway speeds, when tyre roar through the rear wheel housings can become intolerable over long distances, particularly on coarse bitumen surfaces with an empty cargo bay amplifying the noise.

In our experience, this is a problem shared by all vans at these speeds if they’re not equipped with a sealed cabin bulkhead. So, if your work involves a lot of highway travel, we would recommend fitting one that's available in Toyota’s genuine accessories range. Or buying some earplugs.

The HiAce has a five-star ANCAP rating awarded in 2019 which will expire in December 2025. It comes with seven airbags plus benchmark active safety features including AEB with pedestrian and daytime cyclist detection, lane departure alert with braking assist, speed sign recognition, blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, reversing camera and more.

Our test vehicle comes with a five-year/unlimited km warranty.

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

Mazda’s ‘estimated service cost’ for the first five years/75,000km totals $2547 which is an average of $509 annually.

It is covered by a five-year/unlimited km warranty. Scheduled servicing is a relatively short six months/10,000km intervals, whichever occurs first. Capped-price of $290 per service covers the first six scheduled services over three years or 60,000km.
