Mazda BT-50 vs Nissan Navara

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. 

Although the D23 Navara is approaching a decade in local showrooms and due for replacement in 2025, the base-model SL still represents a fuel-efficient and competent workhorse with ample back-to-basics practicality.

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 cabin’s fabric-covered seats, wipe-clean vinyl floor and urethane-rimmed steering wheel/shifter are consistent with the SL’s work focus.

Reminders of its 2015 origins are numerous mechanical switches and dials on the dash (which we prefer to touchscreen versions), a steering wheel with only height adjustment, a mechanical rather than electronic handbrake, rear drum brakes instead of discs and analogue speedo/tacho.

Even so, its interior design still looks a cut above a base-grade ute, with a visually-pleasing and practical blend of chrome, satin chrome and piano black combined with two-tone upholstery.

The well-bolstered front seats are comfortable and supportive, but a larger and more defined left footrest would enhance driver comfort.

Rear passenger knee room is adequate for the two outer seating positions, thanks largely to the concave shape of the front seat backrests.

However, shoulder room is tight for three adults and headroom is marginal, particularly for tall people in the higher centre position who also must contend with a headrest that has insufficient height adjustment.

Like most dual cab utes, short of full-size US pick-ups, the Navara works best as a four-seater with the fifth seat limited to short trips. 

Off-road credentials include a 12.5-metre turning circle, 220mm of ground clearance, a 600mm wading depth and 32 degrees approach, 22.9 degrees ramp break-over and 26 degrees departure angles.

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 relatively light 2033kg kerb weight and 3150kg GVM, our test vehicle has a one-tonne-plus payload rating of 1117kg.

It’s also rated to tow up to 3500kg of braked trailer. However, to tow that weight would require a substantial 740kg reduction in vehicle payload to avoid exceeding its 5910kg GCM (or how much it can legally carry and tow at the same time). Even so, few (if any) Navara owners would need to tow 3500kg.

The load tub is almost square with its 1509mm floor length and 1560mm width. And with 1134mm between the rear wheel housings, it won’t fit a standard Aussie pallet but will take a Euro, held in place by a choice of four load-anchorage points.

In terms of cabin storage, the centre console offers open storage up front, two small-bottle/cupholders in the centre and a small lidded box at the back. There’s also a large-bottle holder and storage bin in each front door, plus a glove box and overhead glasses holder.

Rear passengers get a large-bottle holder and smaller storage bin in each door plus a fold-down centre armrest with two small-bottle/cupholders. The rear bench seat’s base cushion can also swing up and be stored vertically for more internal cargo space, or to access two small underfloor storage compartments.

Our 'Solid White' SL dual cab 4x4 test vehicle comes standard with the same 2.3-litre twin-turbo four-cylinder diesel shared by all Navaras but ours has the optional seven-speed automatic, with a list price of $50,350.

This pricing and healthy 140kW/450Nm outputs make it more than competitive with base-grade 4x4 dual cab ute rivals including the Ford Ranger XL 2.0L auto ($50,880), Toyota HiLux Workmate 2.4L auto ($50,420) and Isuzu D-Max SX 1.9L auto ($50,700).

Our example is also fitted with a couple of items from Nissan’s genuine accessory range, including a load tub-liner and flush-fitting tonneau cover available at extra cost.

Being the base-model workhorse of the Navara’s 4x4 range, the SL’s no-frills standard equipment list is designed with hard work in mind, as evidenced by its 17-inch steel wheels and 255/65 tyres with a matching spare.

There are also halogen auto-headlights and DRLs, tailgate assist (makes lowering and raising easier), a reversing camera and rear diff-lock.

Inside is more useful kit including two 12-volt sockets, three USB ports, centre console cooling/heating vents for rear seat passengers and a driver’s 7.0-inch analogue instrument display enhanced with a digital speedo.

The six-speaker multimedia system has a relatively small (by today’s standards) 8.0-inch colour touchscreen, with multiple connectivity options including Bluetooth, Android Auto and Apple CarPlay.

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 Navara’s 2.3-litre four-cylinder turbo-diesel produces 140kW at 3750rpm and 450Nm of torque between 1500-2500rpm. Its two-stage inline turbochargers (a small one for low rpm, a large one for high rpm) operate in sequence to provide vigorous response at all engine speeds with excellent economy.

A refined seven-speed torque converter automatic offers near-seamless shifting and the overdriven sixth and seventh gears enhance fuel economy at highway speeds.

Drivers also have the option of sequential manual-shifting to provide more direct engine control when off-roading or carrying/towing heavy loads. Its 4x4 transmission is dual-range, part-time and is equipped with an electronic rear diff lock.

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.

Nissan claims an official combined average of 7.9L/100km and the dash readout was showing 7.7 when we stopped to refuel after clocking up just under 600km on the first tank, which included a 400km-plus day trip from Melbourne to regional Victoria.

Our own figure, calculated from fuel bowser and tripmeter readings, came in at a slightly higher but still frugal 8.4L/100km which proves the fuel-sipping efficiency of diesels when highway cruising.

We covered another 168km in city and suburban use, with the dash claiming 8.6 compared to our own figure of 9.5, which is still thrifty single-digit economy for a two-tonne ute.

Therefore, based on our own ‘real world’ figures, you could expect a driving range of about 840km around town and up to 950km on a trip from its 80-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.

The driving position is comfortable for most shapes and sizes, even though the steering wheel does not have reach adjustment and the seat lacks adjustable base cushion rake or lumbar support.

The ride is firm when unladen but its four-coil suspension is absorbent enough to soak up the worst of the bumps. The steering feel is responsive and nicely weighted, combined with competent handling and braking that contribute to a positive driving experience.

It’s also impressively quiet at highway speeds, with low tyre and wind noise and an engine that requires less than 2000rpm to maintain 110km/h with minimal effort.

To test its payload rating we forklifted 830kg into the load tub, which combined with our crew of two was a one-tonne-plus payload of 1010kg. That was about 100kg less than its payload limit.

The supple coil-spring rear suspension compressed 80mm under this loading, yet its high ride height ensured there was still about 40mm of bump-stop clearance remaining, which proved ample in avoiding any bottoming-out on our test route. However, that’s not to say it wouldn’t with an extra 100kg on board.

It also excelled on our 13 per cent gradient, 2.0km-long set climb at 60km/h, with the seven-speed auto self-shifting down to fourth gear and just under 2000rpm (right in the middle of its peak torque band) to easily haul this load to the top.

Engine-braking on the way down, in a manually-selected second gear, was also impressive for a 2.3-litre engine restraining more than one tonne of payload. Overall, the Navara proved to be a competent heavy-load hauler.

The D23 Navara earned a maximum five-star ANCAP rating when launched in 2015, but that rating has since lapsed with all Navaras built from January 2023 unrated.

Even so, it’s armed with seven airbags plus AEB, forward collision warning, trailer-sway control, a reversing camera, hill-start assist, hill descent control and more.

The rear seat has three top-tether and two ISOFIX child seat anchorage points.

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.

There’s a five year/unlimited km warranty, plus five years of 24-hour roadside assist. Scheduled servicing is every 12 months/20,000km whichever occurs first.

Total capped-price of $3305 covers the first five scheduled services within five years, or an average of $661 per year.
