Mercedes-Benz Sprinter vs Isuzu NLR

What's the difference?

It has its niggling faults like any vehicle but the Sprinter panel van is a well-designed vehicle overall. It’s fit for purpose and worthy of consideration if you’re in the market for a heavy commercial van. That is if you have about $90K to spend, which is around $40K more than its closest competitor - and that one comes from China.

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.

This is a sizeable vehicle that’s almost 7.0 metres long (6967mm) and more than 2.0 metres wide (2020mm) and with its ‘High Roof’ design stands more than 2.6 metres (2663mm) tall. If you tick the ‘Super High Roof’ option that raises height to 2878mm.

It rides on a sprawling 4325mm wheelbase with strut-type coil-spring front suspension, a robust leaf-spring live rear axle and four-wheel disc brakes.

Our only gripe in the cabin relates to the single USB outlet, which is awkwardly located inside the dash pad’s lidded central storage bin with no cut-out in the lid to route a device cable through. Placement near the central dash controls (like its smaller Vito sibling which has two USB ports) would be much better.

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.

With a 2372kg kerb weight and 4100kg GVM, this Sprinter van has a substantial 1728kg payload rating. It’s also rated to tow up to 2000kg of braked trailer and with its 6100kg GCM (or how much it can legally carry and tow at the same time) that means it can haul its maximum payload while towing its maximum trailer weight.

The huge cargo bay, with a solid timber floor that looks long enough for landing light aircraft, has a cavernous load volume of 14 cubic metres.

It’s accessed through a large kerbside sliding door with 1260mm-wide opening, or symmetrical glazed rear barn-doors with 180-degree opening for easy forklift access. There’s internal lighting front and rear and the walls and roof are not lined.

Tall people can stand without stooping given the 2009mm internal height. With a 4351mm floor length and 1350mm between the rear-wheel housings, the Sprinter can carry up to three 1165mm-square Aussie pallets or up to five 800 x 1200mm Euro pallets, secured with a choice of 12 load-anchorage points. There are also handy net-type storage pockets in each rear barn-door.

Plenty of cabin storage starts with a large-bottle holder and upper/lower bins in each front door, plus full-width overhead storage shelves with a lockable compartment on the passenger side, four small-bottle/cupholders in the lower central dash, two more small-bottle/cupholders and three ‘clamshell’ lid bins in the top of the dash-pad, an open storage shelf on the lower passenger-side dash and another sizeable enclosed compartment beneath the passenger seat.

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 'OM654' is a 2.0-litre four-cylinder turbo-diesel that meets the toughest Euro 6 emissions standards using AdBlue.

With two-stage turbocharging and auto start/stop technology, it produces 140kW at 3800rpm and 450Nm across a 1000rpm-wide torque band between 1400-2400rpm which showcases its flexibility.

The smooth-shifting nine-speed torque converter automatic offers the choice of sequential manual-shifting using the steering wheel-mounted paddle-shifters, which could be handy when hauling heavy loads particularly in hilly terrain.

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.

Heavy commercial vehicles are not required to provide fuel consumption data. Even so, when we stopped to refuel at the end of our 247km test of which about one third of that distance was hauling a heavy payload, the dash display was claiming a surprisingly frugal combined average of 9.9L/100km (with auto stop/start switched off).

This was close to our own figure, calculated from fuel bowser and tripmeter readings, of 10.5 which means you could expect a ‘real-world’ driving range nudging 900km from its optional 93-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.

Wide door openings and large assist-handles on the windscreen pillars make for easy cabin entry.

Finding a comfortable driving position is not hard either, given the combination of a height/reach-adjustable steering wheel and supportive bucket seat with adjustments for backrest angle, seat-base rake/length and lumbar support.  

The optional 'Campervan Package' seats, with fold-down inboard armrests, can also rotate towards the centre of the cabin. We assume this pivoting function is to aid rear-of-vehicle access, but was of no use in our test vehicle given the mesh cargo barrier.

Our only criticism of the driving position is that the slim pillar between the fixed and sliding glass in the driver’s door partly obscures the driver’s eyeline to the door mirror. However, sliding the seat base forward solves the problem, so it’s only an issue for tall drivers like me that need to sit more rearward.

The ride quality without a load is good, given the robust rear suspension. It also has nicely-weighted and responsive steering plus good braking, along with acceptable internal noise levels at sub-80km/h city and suburban speeds given the absence of a solid bulkhead and minimal cargo bay linings.

However, tyre roar emanating through the rear-wheel housings and amplified by the cargo bay can be uncomfortably intrusive at highways speeds, depending on the coarseness of bitumen surfaces.

So, we’d recommend either installing a solid bulkhead (or use ear-plugs) to reduce noise levels if you’re planning to do regular highway driving in this configuration.

The 2.0-litre turbo-diesel and nine-speed automatic display great efficiency, with throttle response at its most immediate and energetic when operating within the 450Nm peak torque band between 1400-2400rpm.

The refined auto’s snappy but smooth shifting gets the best out of this engine in most situations, without the need to paddle-shift in manual mode.

To test its load-carrying ability, we used up all of our weights to forklift 1300kg into the cargo bay, which was still more than 400kg less than the GVM rating.

As a result, the Sprinter made light work of hauling this 1.3-tonne payload around town, with the only differences being a slightly firmer ride and more accelerator pedal required to maintain engine performance.

It easily hauled this load to the summit of our 13 per cent gradient, 2.0km set climb at 60km/h, although engine-braking on the way down was (as expected) not as strong given its small displacement.

In a manually-selected second gear, road speed quickly increased as the engine climbed towards the tacho’s redline on overrun, before the auto dismissed our manual gear selection and shifted up to third.

This automatic engine-protection protocol is common in Euro vans. However, if you’re not ready for it, it can spring a surprise when you’re leaning on the drivetrain to assist with engine-braking during a steep descent and it suddenly shifts up and starts running away from you. The quartet of disc brakes, though, easily compensated for this shortfall.

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.

The Sprinter is covered by a five year/250,000km warranty including five years roadside assist.

Scheduled servicing is every 12 months/40,000km whichever occurs first.

Capped-price servicing for the first five scheduled services during warranty period totals $7130, or a pricey average of $1426 per service.

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.
