Fiat Ducato vs Isuzu NLR

What's the difference?

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.

Work out the weight of all the tools, equipment, materials, crew and (if applicable) trailer that you need to haul around each day and measure it against this truck’s formidable GVM and GCM ratings. When combined with its compact dimensions, robust design and build quality, solid warranty and ready-to-work pricing, you may find it’s hard to beat if you’re prepared to think outside the square on what a single cab-chassis ute can look like.

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.

This vehicle looks compact in comparison to a one-tonne ute - and the tape measure confirms it. Compared to a Ranger 4x4 dual cab ute for example, its 5020mm overall length is a surprising 339mm shorter, its 2490mm wheelbase is 730mm less and its 1855mm width is line-ball.

The Isuzu’s 2172mm height is 357mm taller, which could present a challenge if access to underground or multi-storey carparks is required. However, its remarkably small 8.7-metre turning circle is a whole 4.0 metres tighter than the Ranger, so it's highly maneuverable.

Built on a heavy-duty steel ladder-frame chassis, it has independent wishbone/coil spring front suspension, a leaf-spring live rear axle, power-assisted rack and pinion steering and four-wheel disc brakes. It also runs a 24-volt electrical system with twin batteries.

The single cab provides fabric-trimmed seating for up to three (driver bucket, passenger bench) but our test vehicle was fitted with seat covers from the Isuzu accessories range. With torsion bar assistance, the cab can be easily tilted forward to rest at a 45-degree angle and provide full access to the engine.

The service body, which is a blend of lightweight aluminium and steel, has a tough powder-coated finish. It comprises a large main storage compartment with big gull-wing doors on each side, plus a compact rear tray with checker-plate floor, drop-sides and load anchorage points. There are also rear underbody storage boxes on each side, plus sturdy body-mounted roof racks, safety yellow non-slip steps and sturdy grab handles front and rear.

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.

With a hefty 2825kg tare weight and 4500kg GVM, the Isuzu has a big 1675kg payload rating. It’s also rated to tow up to 4000kg of braked trailer and with its sizeable 8000kg GCM, it can legally tow that weight with a 500kg reduction in payload. Or you can cap the towing weight at 3500kg and keep the full payload. Either way, these are substantial GVM and GCM ratings for any number of working roles.

In terms of cabin storage, there’s no glove box but both doors have narrow storage bins and there are overhead shelves with restraint netting to keep loose items in check. There’s also a pop-out dual bottle/cup holder in the centre dash along with two small storage nooks, but more places to store things would be welcome in this space.

Our test vehicle, to use its full model name, is the NLR 45-150 SWB AMT Servicepack X. It’s the most compact model in the N-Series range and as a result is similar (and in some cases much smaller) in key dimensions to a one-tonne ute. It only comes in one specification with 3.0-litre turbo-diesel, six-speed automated manual transmission (we’ll get to that) and dual-rear wheels, for a list price of $87,789.

In addition to its service body, this hard-worker comes standard with half a dozen 16-inch steel wheels, 195/75R16C Michelin tyres and a full-size spare. The single cab is well-equipped with useful features like keyless entry with central locking of cab and service body, big door mirrors with power adjustment, heating and lower wide-angle view, driver’s bucket seat with mechanical suspension and weight adjustment up to 130kg, two-way adjustable steering column, cruise control and bright LED interior lighting. Also standard is a 4000kg-rated tow-bar, reversing camera, loud reversing alarm and door-mounted cornering lamps.

There’s also an infotainment system with smallish 6.2-inch control screen and DAB+ radio. Even though there’s no Apple CarPlay or Android Auto, it has multiple connectivity including internet radio via smartphone, external camera inputs, navigation, reversing sensors and tyre pressure monitoring. The driver also gets a multi-information display and there’s plenty of the latest safety tech headlined by AEB.

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.

Isuzu’s 4JJ1-TCS 3.0-litre four-cylinder turbo-diesel is closely related to the 4JJ3-TCX in the current D-Max ute and MU-X wagon. Tuned for hard work and long life, it produces 110kW at 2800rpm and 375Nm across a 1200rpm-wide torque band between 1600-2800rpm. It’s also equipped with a vacuum-controlled exhaust brake which can be switched on or off.

Isuzu’s MYY-6E is a six-speed fully-automated manual transmission, which may sound like a contradiction in terms, However, like the engine, it's designed for a long service life under continuous heavy loads. It uses an electro/hydraulically controlled wet clutch and lock-up torque converter to provide either fully automatic or clutch-less manual shifting. There’s also slow/fast gear engagement control, first gear start (for heavy loads) and normal or economy drive modes.

A handy power take-off (PTO) facility can drive numerous on-site implements, with drive coming from a counter gear on the left-hand side of the transmission case.

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.

Average combined fuel consumption figures are not required for commercial vehicles in this weight division. Even so, the dash display was claiming 13.2L/100km at the end of our 295km test which included about one third of that distance hauling a heavy payload. So, based on those figures you could expect a real-world driving range of around 570km from its 75-litre tank.

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.

The doors open 90 degrees for easy access and there are decent boot-sized steps plus big handles on the windscreen pillars to help you climb aboard.

It’s a different driving position to a ute, as you sit high above the engine with your feet ahead of the front wheels and hands on a bus-style flat steering wheel. There’s also a big left footrest with lots of open floor around it, so there’s ample space to rest your foot given there’s no clutch pedal.

The suspension seat can be easily adjusted to suit a driver’s weight and works well in providing a more comfortable ride. The seat’s base cushion has no rake adjustment but there is some movement available in the backrest. Large glass areas deliver a commanding view ahead and to the sides while the big door mirrors provide excellent coverage of what’s behind. 

Its harsh ride quality when unladen is to be expected as it’s designed to carry permanent payloads between 1.0 and 1.5 tonnes. You do get thrown around, particularly on poor road surfaces with large bumps and dips. However, it’s no worse than the rodeo ride we’ve experienced in some unladen single-cab chassis utes which don’t have the luxury of a suspension seat.

The cab’s insulation ensures low engine and tyre noise, particularly during highway use where the turbo-diesel requires 2200rpm to maintain 100km/h and 2500rpm at 110km/h. The most noticeable noise at these speeds comes from wind buffeting around the mirrors, roof racks etc but it’s far from intolerable, as conversations can still take place at normal volumes.

Braking (particularly when using the exhaust brake) and steering response are good but the automated manual transmission takes some getting used to, as it shifts gears at about the same leisurely speed you would do manually.

These long pauses between cogs can be frustrating when climbing hills, as you naturally want to downshift quicker to avoid losing momentum, but you can’t do it in either automated or manual modes. Isuzu claims that the duration of these automated shifts can be shortened, but after consulting the owner’s manual to make this adjustment, we didn’t notice much if any difference (or perhaps we just didn’t do it correctly).

The engine has good flexibility and does not respond well to aggressive treatment. A more relaxed approach is best, using low rpm to optimise torque.

There’s no ANCAP rating required for vehicles in this weight class. Even so, it does have numerous passive and active safety features including driver and passenger airbags plus advanced driver assistance systems (ADAS) including AEB, forward collision warning, distance warning, lane departure warning, traffic movement warning, cab-tilt warning and more. There’s also a reversing camera, reversing alarm (the loud beep-beep type) and door-mounted cornering lamps.

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.

There's a reassuring standard warranty of six years or 250,000km (unlimited operating hours) whichever occurs first. Includes three years/unlimited km coverage for body equipment, plus six years of 24/7 roadside assistance with unlimited km. Scheduled servicing every 15,000km/12 months whichever occurs first. Choice of servicing packages available.
