Mazda BT-50 vs Fiat Ducato

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 latest Fiat Ducato, in MWB MR configuration with optional nine-speed auto, is a competent competitor in the 3501-8000kg GVM segment. Its class-leading two-tonne-plus payload rating would have considerable appeal for those who need to carry exceptionally heavy loads and we couldn’t find any major flaws in its design and performance. However, the warranty is short and there are niggling issues in terms of driver comfort, which if addressed would increase the Ducato’s appeal.

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.

The MWB MR's front-wheel drive chassis rides on a 3450mm wheelbase with 12.5-metre turning circle. It’s 5413mm long, 2050mm wide and 2539mm tall, so like numerous van rivals in this GVM class it can’t access shopping centre and underground carparks which typically have a 2.2-metre height limit.

Underpinnings are simple and rugged, combining coil-spring strut front suspension with a leaf-spring rigid-tube rear axle that’s well designed for heavy load-carrying, with compressible rubber cones between body and axle that provide a second stage of support. There’s also four-wheel disc brakes, power-assisted rack and pinion steering and ample hard-wearing black plastic protecting the most vulnerable areas of the bodywork from scrapes and dents.

A sealed steel bulkhead separates the cabin from the cargo bay, insulating driver and passengers from load area noise and doubling as a robust cargo barrier. Its sliding window is ideally positioned to allow the driver or passenger to make a quick over-shoulder glance to check that their load is secure. Leg room for the centre passenger is unusually generous, even for tall adults, which would be appreciated by a crew of three.

Interestingly, the rear barn-door windows are heated but there are no wiper/washers fitted. At first this appeared to be an oversight, but having driven the Ducato in heavy rain we were surprised at how spray-free the rear screens remained and how clean they were afterwards.

Our only gripes are that the driver’s left footrest is so short you can only rest your toes on it. It’s a shame the excellent full-length one that resides in the passenger footwell (which of course is the driver’s footwell in LHD models) can’t migrate across the cabin for RHD versions. Driver comfort would be further improved with more rake adjustment in the base cushion.

The small 5.0-inch infotainment screen also makes it difficult to see much detail in the vision provided by the reversing camera. The optional 7.0-inch screen would be an improvement here, but is only available as part of the Comfort and Tech Pack.

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.

The Ducato’s 2060kg kerb weight and 4250kg GVM results in a huge 2190kg payload rating which dwarfs rivals we've tested including the Mercedes-Benz Sprinter, Ford Transit and its Peugeot Boxer sibling. It's also rated to tow up to 2250kg of braked trailer but given that Fiat does not publish a GCM (Gross Combination Mass) number, we can’t confirm if it can tow that weight while carrying a full payload.

The cargo bay, with a competitive 11.5 cubic metres of load volume, has an unprotected load floor that’s 3120mm long and 1870mm wide with 1422mm between the wheel housings. Therefore, it can easily carry two 1165mm-square standard Aussie pallets or three 1200 x 800mm Euro pallets, held in place by eight sturdy load-anchorage points.

There’s also ample forklift access through either the rear barn-doors, which can swing open to 270 degrees with a combined 1562mm-wide opening, or the sliding side doors with their 1250mm-wide openings.

All doors and walls are lined to mid-height and the raised roof cavity allows even tall adults to stand inside without stooping. It also provides a large and very useful storage area over the driver’s cabin, which is ideal for stowing ropes, straps, load-padding etc.

There’s plenty of cabin storage too, with large-bottle holders and two levels of storage bins in each front door. The dashboard offers numerous open storage bins plus small-bottle/cup holders, a glovebox, large overhead map shelf and storage tray under the driver’s seat. The centre seat’s backrest also folds forward to reveal a handy work desk on the back of it, complete with a spring-loaded clip to hold documents in place, a pen holder and two more small-bottle/cup holders.

Our white test vehicle is the MWB MR, which translates to Medium Wheel Base Mid-Roof. It’s one of four Ducato van configurations featuring medium, long and extra-long wheelbases and two roof heights.

They’re all powered by a new 2.3 litre turbo-diesel engine, with a list price of $48,300 for the MWB MR with standard six-speed manual or $51,190 with the optional new nine-speed torque converter automatic like our test vehicle. It also has an extra side-sliding door that adds another $1190.

A few of the standard features include 16-inch steel wheels with heavy-duty 215/75 R16C tyres and a full-size spare (16-inch alloys optional), infotainment system with 5.0-inch touchscreen, USB/AUX connectivity and steering wheel controls, power-adjustable and heated exterior mirror, dual passenger seat with three-point central seatbelt, single cargo bay side-sliding door, twin rear barn-doors with 270-degree opening, reversing camera/rear parking sensors plus an upgraded safety suite headlined by AEB.

There’s also a wide choice of colours and other options including the Comfort and Tech Pack which for an additional $2190 brings a larger 7.0-inch infotainment touchscreen with DAB digital radio, Apple CarPlay/Android Auto, plus sat-nav, LED daytime running lights, automatic climate control and tyre pressure monitoring.

For the same price you can also get a Safety Plus Pack comprising rain/dusk sensor, auto high beam, traffic sign recognition, blind-spot monitoring and rear cross-traffic alert, fog lights, traction control and all-season tyres.

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

The all-new drivetrain features Fiat’s latest 2.3 litre four-cylinder turbo-diesel with Multi-Jet 2 electronically-controlled common rail direct injection, variable-vane turbocharging, intercooler and Euro 6-emissions compliance using AdBlue. It produces 130kW at 3500rpm and (in automatic models) 450Nm of torque which peaks at 1500rpm. In case you’re wondering, the red ‘180’ body badges denote European metric horsepower.

The new ZF nine-speed torque converter automatic is a sweet-shifting transmission which Fiat claims is designed to optimise the engine’s torque delivery and fuel economy. It has a sequential manual-shift function if required, which could be useful if hauling big payloads in hilly terrain, but works most efficiently when left alone.

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.

Fiat does not publish a combined average consumption figure for the Ducato, but the dash display was claiming 10.2L/100km at the end of our test, which covered almost 300km of which more than a third was with a heavy payload. We also had the auto stop-start function switched off. That consumption figure was very close to our own, calculated from fuel bowser and tripmeter readings, of 10.6L. So, based on our numbers you could expect a real-world driving range of around 850km from its 90-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.

There’s a commanding view for the driver thanks to a panoramic windscreen and clear eye-lines to the truck-sized door mirrors. There’s also reasonable but cluttered vision through the central rear-view mirror, which is partly obscured by the centre seat’s headrest.

The cabin bulkhead is effective in all but eliminating cargo bay noise and engine/wind noise volume is commendably low even on the highway. The highest audible intrusion at those speeds comes from the front tyres, which is acceptable on smooth bitumen surfaces but increases on coarser grades.

Its leather-rimmed steering wheel is nice to use and thanks to the driver’s door moulding and fold-down in-board armrest, there’s evenly balanced elbow support to relieve strain on the neck and shoulders.

The engine and nine-speed auto transmission are well matched, providing energetic performance when prodded and crisp, decisive shifting. Long-legged highway gearing allows 100km/h at 1500rpm (which is also bang on maximum torque) and less than 1700rpm at 110km/h. Ride quality when empty or lightly loaded can get bouncy on bumpy roads, which is not unexpected from suspension with a two-tonne-plus payload capacity.

Our main criticism is insufficient rake adjustment in the driver’s seat base cushion. There’s not enough angle available to stop the driver sliding forwards, requiring constant repositioning that becomes tiring after a while. More rake in the base cushion, combined with a decent-sized left footrest, would solve this issue.

Also annoying is the audible lane-departure warning, which is too loud and sounds like you’re being zapped by a ray-gun in an old sci-fi movie if you step out of line. A less confronting warning would be welcome.

There’s no ANCAP ratings for this GVM division and above, but the latest Ducato is equipped with AEB, forward collision alert, lane departure warning, rear parking sensors, reversing camera plus driver and dual-passenger airbags as standard. Buyers can also option the Safety Plus Pack mentioned earlier.

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.

Three years/200,000km warranty looks undercooked compared to the five years/unlimited km offered by some rivals. Scheduled servicing, though, is excellent for hard-working vans at 48,000km/12 months whichever occurs first. Five years of Fiat Professional servicing, based on a total distance of 240,000km, equals $6756.99 or an average of $1351.40 per year.
