Isuzu NLR VS Mercedes-Benz Sprinter

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.

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.
