Mazda BT-50 vs Volkswagen Transporter

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. 

The Transporter boasts a level of mechanical refinement, engine performance, ride quality, heavy load-carrying ability and general driver comfort that sets a high benchmark in this category. If not for its lack of an ANCAP rating and unacceptably high internal noise levels at highway speeds, it would be hard to fault.

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.

Our test vehicle’s 3400mm wheelbase is 400mm longer than the standard model, resulting in a corresponding increase in overall vehicle length to 5304mm and a 300mm increase in turning circle to 13.2 metres.

Its 1904mm width is an easy fit in most loading zones and the standard roof’s 1990mm height means it can access most underground and multi-storey carparks which typically cap vehicle heights under 2.2 metres. It comes standard with a kerbside cargo bay sliding door and single-lift tailgate.

The well-developed front wheel-drive chassis is simple and robust with MacPherson strut front suspension and semi-trailing arm coil-spring rear suspension, the latter equipped with stout rubber cones inside the spring coils to provide a second stage of support under heavy loads. Optional heavy-duty and rough road suspension packages are also available. Brakes are four-wheel discs.

You can always pick a van designed for hard work by the amount of black plastic in body areas prone to high wear and/or scrapes, chips and dents and the Transporter has most of those covered, including the front and rear bumpers, lower rear pillars, hubcaps, door handles and mirrors.

The cabin has a back-to-basics look and feel as highlighted by numerous plastic caps blanking dashboard slots where switches are fitted to higher-equipped models. However, it has most of what you need and none of what you don’t for this working role. Even so, the lack of fold-down inboard armrests and a driver’s left footrest are notable omissions and both would be welcome for long stints 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.

With its 1865kg tare weight and 3000kg GVM, our test vehicle has a genuine one-tonne-plus payload rating of 1135kg and up to150kg of that can be carried on the roof. It’s also rated to tow up to 2500kg of braked trailer but that would require a sizeable 583kg reduction in payload to avoid exceeding the 4917kg GCM or Gross Combination Mass, which is how much it can legally carry and tow at the same time. Or you could keep the full payload and reduce the towing limit instead, from 2500kg to 1917kg, which may be a more useful compromise depending on work requirements.

The cargo bay, which offers 5.0 cubic metres of load volume, is 2975mm long, 1700mm wide and 1410mm high with 1244mm between the rear wheel housings. That means it can carry two 1165mm-square standard Aussie pallets, or up to three 1200 x 800mm Euro pallets, secured by a choice of eight load-anchorage points. However, the single-lift tailgate could make rear forklift access tricky, depending on forklift design and reach. The sliding door has a generous 1017mm opening for kerbside loading.

Although the load floor is bare and there’s no standard cargo protection for driver and passenger (optional rubber load floor mats and cargo barriers are available), the cargo bay walls and doors are lined to mid-height and the roof is also lined, with two roof lights providing ample illumination.

Cabin storage includes a large-bottle holder and huge storage bin in each front door, with a narrower second-tier storage shelf above which is ideal for holding smaller items like wallets, keys etc.

The dash provides another small-items cubby to the right of the steering wheel and the top dash-pad has small-bottle/cup holders at each end plus a steeply-angled open tray on the driver’s side which is ideal for storing clipboards, paperwork etc.

There’s no overhead sun-glasses holder but the passenger side of the dash offers two tiers of open storage and a large glovebox, plus another small-bottle/cup holder to the left of the gearshift console. An overhead storage shelf would be handy, given that there’s no centre console.

Our test vehicle is the long wheelbase variant with standard roof height, TDI340 turbo-diesel engine and seven-speed dual-clutch automatic transmission for RRP $47,990. This compares to higher-selling mid-sized turbo-diesel rivals like the Ford Transit Custom LWB 340L with six-speed auto ($47,590), Hyundai iLoad with six-speed auto ($42,710) and segment-leading Toyota HiAce LWB with six-speed auto ($45,240).

It's basic and work-focused as you’d expect, from its 16-inch steel wheels and 205/65R 16C tyres with full-size spare to its cloth seats and tough rubber floor covering in the cabin. However, that doesn’t mean you miss out on some useful and welcome creature comforts, like a leather-covered steering wheel with height/reach adjustment and infotainment controls, driver’s seat adjustable lumbar support, halogen daytime running lights (DRL), rain-sensing wipers, heated tailgate window with washer/wiper, multi-function driver’s display, four-speaker infotainment system with 6.5-inch touchscreen and multiple connectivity including Apple CarPlay/Android Auto plus lots of standard safety tech.

There’s also heaps of factory options available to help tailor a Transporter to suit an owner’s specific requirements including different cargo bay door and window configurations (including twin rear barn-doors), front passenger bench seat with under-seat storage, higher-spec infotainment systems and lots 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

This engine and transmission combination is the jewel in the Transporter crown with its energetic, flexible and efficient performance. The 2.0 litre, four-cylinder, direct-injection TDI340 turbo-diesel meets Euro 6 emissions using AdBlue and produces 110kW between 3250-3750rpm and 340Nm of torque across a 1500rpm-wide torque band between 1500-3000rpm.

The closely-spaced ratios in the seven-speed dual-clutch automatic are tailored to get the most out of this willing engine, with crisp and virtually seamless shifting. It also offers the choice of manual sequential-shifting, when hauling heavy loads in hilly terrain or simply for those wanting a more ‘sporting’ driving experience, but the seven-speeder usually does its best work when left to its own devices.

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.

We covered 283km (with auto start/stop disabled) which included about one third of that distance with a maximum payload. The dash display was claiming an average combined consumption of 8.1L/100km when we stopped to top-up the 80-litre tank. Our own figure calculated from fuel bowser and tripmeter readings came in even lower at 7.7 and both undercut VW’s official combined figure of 8.3L/100km. Needless to say, that’s outstanding real-world economy, which based on our figures should deliver a huge driving range of 900-1000km from its sizeable 80-litre tank. Possibly even further with auto start/stop enabled.

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.

Four-coil suspension provides a noticeably supple unladen ride quality, which is impressive for a commercial vehicle with a one-tonne payload rating. It also feels sure-footed and well planted on the road, particular on the many wet roads we encountered during a rain-affected week of testing.

With its upright steering wheel angle and nicely-weighted steering feel, it offers a comfortable almost car-like driving experience. The driver’s seat has height, backrest rake and lumbar adjustment; there’s no rake adjustment for the base cushion but it doesn’t really need it. There are also clear eyelines to all mirrors, a nicely-positioned gearshift and an uncluttered dashboard/instrument layout that’s easy to read and operate.

The 2.0 litre turbo-diesel has energetic response in its peak torque band between 1500-3000rpm, where most city and suburban driving occurs. Snappy, seamless up-shifting occurs between 1500-2000rpm, providing brisk acceleration with excellent fuel economy. At highway speeds, good gearing ensures the engine needs only 1800rpm to maintain 100km/h and 1900rpm at 110km/h.

We only have two criticisms. One is the size and limited wide-angle effect of the left-side mirror, given the huge blind-spot that a solid-walled long wheelbase van like this creates over the driver’s left shoulder. Although the Transporter is (thankfully) equipped with blind-spot monitoring, a larger kerbside mirror with a more convex shape to increase its angle of view would be welcome.

The other is high internal noise levels at highway speeds emanating from the rear wheel housings. On some grades of coarse bitumen it can sound like the roar of a jet engine, which is too loud for sustained periods and could be a deal-breaker if you do a lot of highway work. We have recently tested rival vans without cabin bulkheads which have appreciably lower cargo bay noise levels at similar speeds (most notably a Chinese brand), so it can be done.

There's no ANCAP rating but the Transporter 6.1 adds to an already extensive list of active and passive safety with the following features now standard: front assist with city emergency braking (aka low-speed AEB), crosswind assist, side-assist including blind-spot monitoring/rear cross-traffic alert and multi-collision brake. There’s also driver and passenger front and side curtain airbags plus lots 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.

Five years/unlimited km warranty with 12 months complimentary roadside assist. Scheduled servicing every 12 months/15,000km whichever occurs first. Capped-price servicing for first five scheduled services up to five years/75,000km of $3082.
