Renault Koleos vs Isuzu NNR

What's the difference?

To be fair to Renault, when the second-generation Koleos launched in 2016, it was a competitive offering. The problem is, a bunch of medium SUV rivals have been replaced in that time and some of them - Toyota RAV4, Kia Sportage, Mazda CX-5 and Hyundai Tucson, to name a few - are high-quality offerings with an engaging drive and the latest tech and in-car features.

Unfortunately, that leaves the Koleos towards the rear of the medium SUV pack.

It offers solid value-for-money, handles reasonably well and is still one the best-looking SUVs on the road. But beyond that, the Koleos can’t keep pace with those top-notch rivals.

A truck like the NPR (or any other truck, really) is never going to replace a dual-cab ute in terms of its duality. While the latter can tend to weekday chores and be quickly reconfigured for weekend fun, the light truck has no such facility. Nope, it’s a workhorse. Period.

You need a fair bit of real estate just to park the Isuzu overnight and it certainly won’t fit in the typical supermarket car space. It’s hardly sporty to drive, either, although the latest upgrades have made it more user friendly in a total sense and safer than ever before.

But what it does do that a dual-cab ute can’t often do, is tackle bigger, heavier jobs with a fair bit of bandwidth still up its sleeve. And if the nine-to-five side of things is where you need to be, then a vehicle like this has to be worth a look. And if you consistently find that you’re sailing close to the wind in terms of exceeding a ute’s legal payload, towing capacity or GCM, then the extra bigness of a light truck could make a huge difference.

That’s especially so given the price tag. Okay, you’re not buying a lot of high tech for your money, but you are getting some seriously stout engineering and an expectation that you won’t be working the thing to death anytime soon.

An area that Renault has excelled at in the past decade has been exterior design. Under the stewardship of design chief Laurens van den Acker, Renault has transformed from somewhat quirky to modern and sleek.

The Koleos is getting on in years, having arrived in 2016, but it’s still a handsome SUV. A 2020 facelift sharpened its looks further and we reckon it’s one of the best-looking models in the medium-SUV segment.

Piano black inserts around the gear shifter are a nice touch, but the fake carbon-fibre inserts look and feel cheap. It’s all a bit generic.

But the appealing contrast yellow stitching on the seats, gear shifter housing, doors, centre armrest and more breaks up the grey with a little pop of colour.

It can’t be easy to make a light truck look fashionable, but Isuzu has done a reasonable job of making the thing look, at least, current. The lighting has all been changed to LEDs now, and the bold, angular face the truck presents looks pretty modern.

But new tech has also forced some design changes. The bull-bar that is part of the Tradepack deal, for instance, has been redesigned with changes to the main hoop. That’s all to accommodate the radar units inside each headlight that inform the front cross-traffic warning system of anything in the way.

Also notable is the attention to detail of the optional (rather than the alloy tray seen here) Australian-made service body. With a choice of internal layouts, the flip-up sides reveal a proper workshop on wheels when configured that way.

It’s also nice to see that all the clips and catches on the drop-side tray can be easily replaced if damaged.

It might lack the up-to-date styling of those rivals, but the Koleos is practical and spacious inside and great for family duties.

As with the outgoing fourth-generation Nissan X-Trail, the Koleos is one of the larger offerings in the medium SUV segment, and it’s evident when sitting in the front or rear seating row.

Rearward visibility could be better, with a small rear screen and thick C- and D-pillars impeding vision and creating a blind spot.

The front seats are well supported and comfortable and while the driver’s side is power adjustable, the front passenger seat is manually adjustable.

It has a deep central storage bin with a hidden shelf for coins and more. The Koleos features a sizeable glovebox and good bottle storage in the doors, with room for other items.

There’s a weird fixed cup holder in the centre console. It’s not adjustable and there’s room for two very narrow cups and two larger, but not wide, cups. It’s strange. Interior designers could have used that space better.

The CVT's position indicators are located to the left of the shifter and are thus obscured, so you have to rely on the instrument cluster display to confirm what gear you want. 

The steering wheel looks and feels good, but the controls aren’t super logical. There are old school switches in the console to activate the cruise control and speed limiter, but then to adjust and reset the speed you have to hit buttons on the wheel that are not clearly marked. 

The audio controls are housed on a panel-like stalk to the right side of the steering column, which isn’t ideal. These make more sense if they’re housed on the wheel itself. 

Along with a number of cars we have sampled recently, the Koleos has split analogue and digital controls for the air conditioning. Just integrate it in the screen or have traditional controls - not both!

It has a part-digital instrument cluster which is fine, but there’s no head-up display.

Renault’s 'R-Link' multimedia set-up in the Koleos is old, with dated graphics and a small screen, but the menu layout is clear and logical. 

The Koleos lacks wireless phone charging and it makes do with wired Apple CarPlay and Android Auto. The quality of the Bluetooth and CarPlay phone audio is poor and sounds tinny. 

The proximity key that locks and unlocks the vehicle remotely when you walk towards or away from it works every single time. Many of these systems from other brands are patchy at best but the Renault system is faultless. 

The rear seats recline and fold manually 60/40. They’re also surprisingly comfortable. There’s enough bucketing to sink in a bit, and the seats are set high up so kids can easily see out windows.

Space is ample in the second row, with loads of head, leg, toe and knee room, even behind my six-foot (183cm) driving position.

The rear pew has ISOFIX points on the outboard seats, lower air vents, a 12-volt outlet, map pockets, a centre folding armrest with two cupholders, but no USB ports. You have to make do with the two ports at the front.

Open the power tailgate and you’ll find a decent 458-litre boot with all seats in place (maximum 1690L), which is off the pace of its cousin, the Nissan X-Trail (565L), as well as the Toyota RAV4 (580L) and Hyundai Tucson (539L).

A 17-inch steel spare wheel is housed under the boot floor which might explain the lower boot capacity, and there are handy tie-down hooks, a couple of smaller storage nooks and a solid cargo blind. 

The new cabin Isuzu has brewed up certainly brings the truck into the present, but it’s still very much a light truck in some respects. As in, it’s still a pretty good climb inside, although there are steps and handles to make that easier. The steering column still gets in the way as you swing your left leg inside, though.

The plastic surfaces would still make a car interior designer cringe, and the floor is vinyl and the seats cloth. But the three-abreast seating arrangement makes sense and, should you choose the dual-cab N Series option, there’s actually seven seats in all.

Cabin storage has obviously been a priority for Isuzu, and there are three large, netted overhead bins above the top of the windscreen, as well as bins and buckets across the width of the lower dashboard. Interestingly, each door has just a single, slim pocket and no bottle storage.

The centre console addresses that somewhat with a pair of cup-holders and a pen slot, while there’s also a large bin behind the seat on the bulkhead. There’s also an interior light that wouldn’t look out of place in an industrial kitchen.

The dashboard is home to a pair of USB charge-ports in the centre and the truck stuff continues with a wand for the exhaust brake and a knob near the steering column for a fast-idle setting. It’s also nice to see that even though Isuzu has adopted keyless entry and start for the N Series, the starter button resembles a conventional key and is located right where it should be in the side of the steering column.

What’s missing? Mainly a vanity mirror on either side of the cabin and a physical volume knob for the stereo. Oh, and paddle shifters would be nice too, especially when towing.

Externally, the Tradepack option gets you an aluminium drop-side tray, sturdy ladder racks, a tow bar, bull bar, toolboxes fitted below the tray between the axles and even a wash station for after-work clean ups.

The tray is fitted in Australia (many of the Ready to Work body options are also made here) and the load floor is a vast expanse of alloy with the ability to cope with small, heavy objects thanks to its high-impact materials. But the usual drop-side tray caveats apply including a high loading height, rattling from the sides and the legal requirement to lash everything down before hitting the road.

Meantime, part of the overall appeal of the Isuzu line-up is that there are something like 40 different permutations of cabin width, wheelbase, GVM, overall length and driveline.

But here’s perhaps the N Series’ greatest trick when it comes to being practical: While it’s easy to dismiss the vehicle for being too big and unwieldy, many operators would possibly find that the extra payload and real estate in the cargo area means that they might not need to tow a trailer every time they venture on to a job site. At which point, the dual-cab ute with a tandem trailer starts to look less convenient, especially if there’s any reversing or squeezing on to a tight site involved.

Oh, and if tight spaces really are an issue, the N Series’ sub-10m turning circle makes a typical dual-cab’s 12.5 metre turning circle look ridiculously ungainly. And that’s before we get to that trailer.

Typically for a vehicle like this, a full-sized spare tyre is included.

Like the rest of the N Series line-up, the NPR Tradepack model we’ve chosen to review here is available in a range of cabin widths and wheelbases and even a choice of Gross Vehicle Mass. But first, let’s break down the badge. In Isuzu-speak, N stands for the smallest family in the light-truck line-up. As such, it can be driven on a normal car license in Australia.

The P stands for the GVM, in this case that license-friendly 4.5 tonnes, although you can opt for the higher, 6.5-tonne GVM at which point an endorsed license is required.

And, finally, R is Isuzu’s in-house code for a truck that is two-wheel-drive and uses conventional steel-spring suspension rather than air suspension.

Isuzu says the Tradepack option with its large tray and fittings is a very popular one, so that’s what we’ve concentrated on here. That pack equates to all the drop-side tray, racks and fittings, so it’s a comprehensive add-on. Of course, you can take your NPR as a bare cab-chassis, too, and save by swapping over the tray and fittings from your old truck.

Beyond the nuts and bolts stuff, the NPR includes LED lights all-round, heated and powered exterior mirrors (and they’re huge), keyless entry and start, cruise control, steering-wheel mounted controls, climate-control air-con, a suspension driver’s seat and a tilt and reach adjustable steering column. There’s also a 10.1 inch multimedia screen in the centre of the dashboard, digital radio, sat-nav and wired Apple CarPlay and Android Auto connectivity.

The features that tell you this is still a truck and not a passenger car include the steel wheels, cloth seat trim and vinyl flooring.

As it sits, the NPR Tradepack costs $86,014 on the road, but that’s an all-up figure, and not one where you then have to arrange your own accessories and bits and pieces. It’s also within a few hundred dollars of the Ford Ranger Super Duty Super Cab which, perhaps not so coincidentally, has an identical GVM of 4000kg, GCM of 8000kg and slightly more towing capacity of 4500kg versus the NPR dual-clutch’s 4000kg.

The Koleos shares its powertrain with the X-Trail. That means it uses a Euro 5-rated 2.5-litre four-cylinder, naturally aspirated petrol engine delivering 126kW of power at 6000rpm and 226Nm of torque at 4400rpm.  

It is paired with a CVT and drives with the front, or all four wheels, depending on the grade. 

The Koleos has a braked towing capacity of 2000kg.

Believe it or not there’s actually a family connection between the 3.0-litre turbo diesel in the Isuzu NRL and the Isuzu D-Max dual-cab and MU-X SUV.

While the displacement of the D-Max remains, the unit in the light truck has been retuned to liberate more torque at lower engine speeds. In this case, that’s 129kW at 2860rpm and 430Nm of torque anywhere between 1450rpm and 2860rpm. That gives the engine great flexibility, but the transmission also plays a part.

That’s either a six-speed manual or a nine-speed dual-clutch unit. The latter has either manual or fully automatic shift modes, and it’s worth is backed up by the potential for lower fuel consumption thanks to the inherent efficiency in such a transmission as well as the three extra ratios.

Designed and made in-house at Isuzu, the brand says it’s confident the wet-clutch unit doesn’t carry the potential flaws of some other dual-clutch units we could name. That said, Isuzu has downgraded the towing capacity from 4.5 to four tonnes if the nine-speed is fitted.

And just like any good truck, there’s the provision for a power-take-off on the side of each transmission option, as well as an exhaust brake to help the mechanical brakes when fully laden.

Unlike many light trucks before it, the Isuzu doesn’t get stuck with a rigid front axle. Instead, you get a proper independent set-up with coil springs, while the rear end remains a live axle with leaf springs in the interests of carting lots of heavy stuff.

According to Renault, the combined fuel consumption figure for the FWD Koleos is 8.1 litres per 100 kilometres. The AWD Koleos sips 8.3L.

After a week of mixed urban, freeway and semi-rural driving, we recorded 11.3L/100km.

Koleos uses 91 RON petrol, has a 60-litre fuel tank and emits 188g/km of CO2 emissions.

This is a cursed subject in the truck segment, because there’s just no standard pattern of usage, nor a typical loading scenario. Some trucks will spend their whole lives heavily loaded going from red light to red light, others will be less burdened and driven between regional towns.

But what we can tell you is that unladen and driven sensibly, this truck should be able to return fuel consumption figures in the low teens per 100km. Throw the full payload and a trailer on the back and head for hilly country and you could easily double that and then some.

As such, the range from the 100-litre fuel tank is going to vary enormously, but should be somewhere between 500 and 800km.

The other thing to bear in mind is that the upgrade to this model has brought the Isuzus in line with Euro 6 emissions or their Japanese equivalent. So they now need AdBLue and there’s a 14-litre tank for that.

The drive experience is a mixed bag with some highlights and lowlights.

The ageing 2.5-litre engine is responsive enough from a standing start - it has a 0-100km/h time of 9.5 seconds - but it lacks any real punch and becomes breathless the second you encounter a hill.

It is noisy and revs hard when pushed, with the CVT drone not making for a particularly pleasant aural experience. You’ll hear a fair bit of road and tyre noise in the cabin, too.

The steering is dull and feels quite artificial, but the brakes feel strong.

Unless you’re on a perfectly smooth road surface, the ride is a little busy and the damper tune fails to adequately soften corrugations, potholes and speed bumps. 

It is, however, a more capable handler than expected. The chassis is well sorted, and aside from feeling top heavy with body roll when cornering, it has decent grip and displayed impressive roadholding characteristics, even on a sweeping bend with a loose shoulder surface.

There was a little understeer detected turning into a particularly tight bend.

It can’t match the dynamism of the Kia Sportage or Mazda CX-5, but it does engage the driver to some extent.

Actually climbing aboard the Isuzu is job one, and you’ll need the handles and step to do it safely. Then again, it’s probably no more testing than getting into a really low sports car in a degree of difficulty sense.

With that accomplished, you’re met with two things; the view out and the very un-car-like driving position. The first is fantastic for forward vision. And it’s not just the height advantage over other traffic. The cab-over-engine layout also means you’re almost at the very front of the truck, meaning you can see a lot more of what’s directly in front of you, even if it’s almost under your nose. Jumping back into a dual-cab ute for comparison emphasises the point enormously.

The driving position, meanwhile, might take more getting used to. The steering wheel is almost flat and you tend to sit pretty upright. Long-distance drivers will tell you this is actually great for long stints at the helm, and it honestly feels pretty natural after just a few minutes. But the steering column placement means there’s no chance of left-foot braking which some drivers (this one included) prefer.

Once you’re rolling, the dual-clutch transmission starts to feel pretty handy with short, sharp upshifts and a calibration that sees it keen to downshift on deceleration to help balance the vehicle, take the stress off the brakes and ensure that the engine is in its power band for when you next throttle on.

Speaking of which, the engine is not exactly overpowering, but it does produce the meat of its muscle in the right places, helped no end by having nine ratios to play with. And here’s an interesting point: The way the engine is installed in the NPR – and despite the fact that you’re sitting pretty much right on top of it – there’s less noise and vibration from the 3.0-litre than in an Isuzu D-Max ute. Obviously, low vibrations and less noise are factors in staving off driver fatigue, and clearly Isuzu knows how to achieve this.

Ride quality will vary hugely depending on what’s on board. We tried the NPR with a full load of gear on the tray, taking it almost to its payload limit. At that point, the ride was actually quite compliant, and the only odd sensation is that of having your backside right over the front axle.

The other mantra held dear by fleet managers is that the best way to reduce breakdowns is to take the driver out of the equation as much as possible. That explains the dual-clutch transmission, for one, but it also perhaps explains why the NPR is set up to be actually very easy and simple to drive. It’s definitely scarier to look at than to pilot. And that turning circle is something else!

You can absolutely thank OH&S legislation for the huge leaps in active and passive safety that vehicles like the Isuzu have made in recent years.

Although this class of vehicle is not required to be crash tested (and, therefore, there’s no safety star rating available) even a scant knowledge of physics suggests that sitting the passengers up high in a vehicle with a strong chassis is a very good start when it comes to crash safety.

Passive safety is also helped by an airbag for both driver and the two front-seat passengers in the case of the three-seat variant we’ve looked at here. But only the outboard passengers get a three-point seat-belt, and the centre position gets a simple lap-belt.

There are also side intrusion bars in the doors as per passenger-car best practice and the overhead storage space features a safety net. There are no side-curtain airbags, but again, that high seating position makes the N Series inherently safer for passengers in a typical side impact.

But it gets better with a long list of driver aids, most of them straight out of the current passenger-car playbook. Running changes to the vehicle over the years have seen the addition of autonomous emergency braking (AEB), anti-skid brakes, stability control, a driver attention monitor, a distance warning system for vehicles in front, brake-force distribution and lane departure warning.

New safety tech this time around includes front cross-traffic alert and braking, mis-acceleration (pedal-error) mitigation, traffic and speed-sign recognition, a distance warning system that also advises of the speed of the car in front and improvements to the rear camera system.

And yet, there’s probably more work to be done here. We’d like to see a standard 360-degree camera and tyre pressure monitoring as well. These are both available at extra cost right now, but really should be standard on a vehicle like this. Rear cross-traffic alert is also missing, but that’s more about standardising the sensors and their calibration on a huge range of rear-body designs, apparently.

There’s also an apparent tech gap to be bridged, too, and right now only the dual-clutch-equipped version gets the speed limiter and adaptive cruise control, while the conventional manual does not.

Isuzu is also making a big noise about the new electronic park brake which can be used in an emergency to bring the vehicle to a complete, controlled stop if necessary.

The Koleos is covered by Renault’s five-year/unlimited kilometre warranty, which is stadatd in the meainstream market, now. 

It is available with a five-year capped-price servicing plan, with each service costing $429, except year four which will set you back $999.

The servicing schedule is every 12 months or 30,000km, whichever occurs first.  

Despite the hard life many trucks are destined to live, Isuzu offers a standard six-year/250,000km warranty on the cabin and chassis of this model. The rear RTW body (whatever form that takes) is covered for three years. There’s also a three-year warranty on genuine accessories provided they were installed by a certified fitter.

Service intervals are every 25,000km, 12 months or 5000 hours of operation, whichever comes first. There’s also six years of roadside assistance thrown in.

Isuzu offers a range of service agreements ranging from the basic package right up to a plan that covers everything including wiper blade replacement.

There are currently 84 Isuzu dealers or authorised service outlets around the country, including some pretty far flung spots, so service and parts should be less of a problem than for some other brands.

Mechanically, Isuzu has worked to reduce servicing times, including the use of sealed-for-life wheel bearings.
