Isuzu MU-X vs Renault Koleos

What's the difference?

The MU-X has plenty of appeal as a daily driver – dependable and it’s a proven 4WD wagon.

Does the 2.2-litre engine add anything substantial to the mix?

Well, it's better than the 1.9-litre, that's for sure, and there's a lot to like about this MU-X in terms of its off-road capability, driver-assist tech, standard features and all-round driveability. And, while the LS-T lacks the top-shelf polish of the X-Terrain, it’s still an appealing potential purchase.

But the 3.0-litre option is better because while the 2.2L is very effective off-road and general day-to-day driving, it lacks grunt and has to work that much harder and is that much noisier under load than the 3.0-litre in most driving scenarios, including 4WDing.

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.

In terms of appearance, the MU-X remains largely unchanged from the most recent iteration. And that’s a good thing. It’s blocky enough to be recognisable but sleek enough to remain inoffensive. Worth noting the door handles, window trims, front fender accents, roof rails, and side steps on the LS-T are gloss black.

Inside, nothing much has changed (other than a newly-introduced idle start/stop button) and, as such, the MU-X retains a low-key familiarity that makes it a comfortable space. Generally, design-wise, the MU-X more than holds its own against the likes of the Toyota LandCruiser Prado and Ford Everest.

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.

The interior has a familiar and practical feel about it and the cabin is an easy space in which to become comfortable. Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C (front and second row) and 12V.

Storage places include recesses for the bits and pieces from your pockets, a deep-ish centre console, as well as dual cupholders up front, cupholders in the rear fold-down centre armrest and bottle holders in the doors. There are also cupholders either side of the third row.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume and access sat nav).

Seats are comfortable and supportive through all three rows – yes, even the third row is roomy enough to prevent whining from whoever is back there.

My camera guru/photographer/sergeant-at-arms, Glen Sullivan, reminded me that the third-row seats don’t have ISOFIX or top-tether points for child seats. Thanks, mate.

The cargo area is 311 litres with all three rows in use, 1119L with the third row flat and 2138L with the second and third rows stowed away.

The rear cargo area has a cargo cover, tie-down points, a 12V power outlet, a storage space under the rear cargo area floor and a space for tools inside the driver’s side rear cargo wall. The MU-X’s full-size spare (bravo!) is attached to its undercarriage.

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. 

A European badge doesn’t always mean you pay more than say, Korean or Japanese offerings, and Renault is an example of that.

The Koleos line-up, for now, starts from $33,590, before on-road costs, for the two-wheel drive Life and tops out at $46,390 for the Intens all-wheel drive.

But after July 1, 2022, prices will increase across the Renault line-up, with the Koleos set to range from $35,000 to $47,500.

There’s only one petrol engine option since the diesel was dropped in 2019 and each variant is paired with a continuously variable transmission (CVT) driving either the front or all four wheels.

That pre-July pricing is competitive against its rivals, undercutting the opening price of automatic versions of the Hyundai Tucson, Kia Sportage, Mazda CX-5, Mitsubishi Outlander, Subaru Forester, Toyota RAV4, and more.

Our test car, the Koleos Black Edition, is priced at $40,090 (rising to $40,500 from July 1) and is based on the specification of the mid-range Zen front-wheel drive (FWD). It is limited to 400 units in Australia.

Renault is one of a number of car makers to offer a black-themed model in recent times, alongside Kia, Mitsubishi, Toyota, SsangYong, and others.

The Black Edition adds dark flourishes like 19-inch dark-grey alloy wheels, gloss black roof rails and door mirrors, sidesteps, French flags on the B-pillar (even though it’s built in South Korea) and a choice of three exterior metallic paint colours including black (of course), grey or white. 

It also gets a hands-free powered tailgate, black synthetic leather upholstery with yellow stitching, matt carbon-look inserts, an 8.7-inch multimedia portrait touchscreen and ‘Limited’ badging on the chrome door sills.

That’s on top of features that are standard on the Zen, like a proximity key, push-button start, dusk-sensing headlights, rain-sensing wipers, auto-dimming rear-view mirror, auto-folding exterior mirrors, an electrically adjustable driver’s seat, heated front seats, a reclining rear seat, dual-zone air-conditioning, and heated and cooled front cupholder.

The multimedia system houses sat nav and comes with wired Apple CarPlay and Android Auto, Bluetooth, digital radio and an eight-speaker audio system.

There’s more details on the safety front below, and many rivals come with more modern in-car tech but there’s no question the Koleos offers very good value-for-money. 

This MU-X has a 2.2-litre, four-cylinder, turbo-diesel engine, producing 120kW at 3600rpm and 400Nm between 1600-2400rpm and it’s matched to an eight-speed automatic transmission.

Worth noting the 3.0L MU-X has a six-speed auto and produces 140kW (at 3600rpm) and 450Nm (1600-2600rpm) while the outgoing 1.9L MU-X has a six-speed auto and produces 110kW (3600rpm) and 350Nm (1800-2600rpm).

While the 3.0-litre has always been unstressed in most driving scenarios – even low-range 4WDing – the 2.2-litre feels underpowered. More about that in the ‘Driving’ section below.

The MU-X has a part-time 4WD system which includes a dual-range transfer case (with high- and low-range 4WD) and a rear diff-lock. The driver is able to shift from 2H (two-wheel drive, high-range) to 4H (4WD high-range) while on the move up to speeds of 100km/h. The diff-lock may only be engaged when the vehicle is in 4L (4WD low-range).

The MU-X also has a switchable terrain mode system which tweaks the engine, transmission and traction control to suit the driving conditions. 'Rough Terrain' mode, like a steroids-enhanced off-road traction control, is king of these modes when you’re off the bitumin.

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.

Official combined cycle (urban/extra-urban) fuel consumption for this MU-X is 6.7L/100km. The 1.9L MU-X offers 7.4L/100km while the 3.0L offers 7.6L/100km.

Actual fuel consumption on this test was 8.7L/100km.

The MU-X has an 80-litre fuel tank, so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 920km. But remember, your fuel consumption may be completely different to mine because chances are you'll have friends, family pets, sporting equipment, camping gear, the whole kit and caboodle on board. I've only been carrying vehicle recovery gear, MaxTrax, and a first-aid kit, so I haven't had a huge amount of weight on board.

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.

Before we launch into the off-roading section of this test, it’s worth noting the MU-X has always been decent on-road; composed, reasonably refined (for a 4WD wagon, anyway) and comfortable. And thankfully, with the 2.2-litre engine, not all of those characteristics have been thrown out the window.

It is quite noisy, especially under pressure when you have to do some heavy acceleration or when you have a bit of gear on board. When it has to work that bit harder than it usually does, it can become quite noisy. Admittedly, the 3.0-litre MU-X is also quite gruff, but there's an edge to the roughness in the 2.2-litre that is very noticeable on road.

This MU-X is quite sluggish off the mark, exhibiting a disconcerting lag under heavy throttle from a standing-start. And it’s far from the most dynamic vehicle to drive. But it has a tractability about it that manages to mostly negate these flaws.

Otherwise, the new eight-speed auto deserves credit as it’s slick and smooth in application and feels right at home in this wagon.

Now to off-roading. The MU-X is still very capable. In fact, even with the 2.2-litre engine, it remains one of the better-performing 4WD wagons straight out of the dealership, in terms of pure off-road capability.

The 3.0-litre MU-X is not the torquiest in this segment, but it offers ample pulling power available across a wide rev range – count on peak torque between 1600rpm and 2400rpm – and it delivers that pulling power in an even-handed fashion. The 2.2-litre MU-X has to work harder than its stablemate, and it’s noisier and harsher.

However, those characteristics don’t take away from how effective this MU-X is because it offers impressive off-road performance. It still has a decent amount of low- and mid-range torque, which makes dirt-road cruising and low-speed 4WDing easy.

The MU-X has part-time 4WD with high- and low-range 4WD gearing, a rear diff lock and overall it retains all of that off-road capability the 3.0-litre MU-X has been renowned for – so you don't lose any efficacy there.

The line-up’s off-road traction control system, which once was a bit patchy in its effectiveness, has gone through a couple of phases and it’s been recalibrated/tweaked over the years and it is much better now.

Of course, the MU-X also has Isuzu’s much-vaunted Rough Terrain mode (a form of early-acting off-road traction control which converts lost grip into torque for the wheels with grip), and it is smooth and effective, giving the driver better overall control in challenging terrain.

Some of this MU-X’s listed off-road angles appear shallower than the 3.0-litre MU-X’s – approach: 23.9 (3.0L = 29.2), departure: 26.4 (3.0L = 26.4) and ramp-over: 19.6 (3.0L = 23.1) – but, even if that is the case, it has very similar driving characteristics in low-speed, low-range four-wheel driving to its 3.0-litre stablemate.

If you drive with control and consideration, you shouldn't have any trouble tackling light to moderate 4WDing in this MU-X. It could even, if push comes to shove, handle challenges that may be considered by some to be on the edge of hard-core 4WDing – for a showroom-standard 4WD wagon anyway.

Ground clearance is 235mm and wading depth is 800mm, so there’s an adequate amount of clearance to work.

The MU-X – with a turning circle of 11.6m and a kerb weight of 2130kg (3.0L = 2185kg) – feels quite nimble on bush tracks.

This wagon’s wheel travel – how far the axle can move up and down relative to the chassis – has more than an adequate amount of flex, stretching its tyres close, if not all the way, to the dirt.

A noticeable trade-off is its 20-inch wheel-and-tyre combination, which is best suited to sealed surfaces and so are far from ideal for dirt-track touring. There’s an easy remedy, though. Buy a set of decent all-terrain tyres on 17- or 18-inch rims to replace the showroom-standard 265/50R20 Highway-Terrain tyres. If you are using your MU-X, avoid dropping pressures too much because you’ll risk sidewall pinches and punctures on these low-profile road tyres.

In terms of packability: the 2.2L MU-X has a listed payload of 670kg, whereas the 3.0L version offers 615kg.

The 2.2L MU-X can legally tow 750kg (unbraked trailer) and 3500kg (braked), so theoretically you can tow the same load as a 3.0-litre MU-X. But, as mentioned, the 2.2-litre engine feels underpowered, even in general day-to-day driving, so with a load and/or towing that’s an added burden.

For reference, the 2.2L MU-X has a listed gross vehicle mass of 2800kg and gross combined mass of 5900kg.

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.

The Koleos was awarded a five-star ANCAP crash safety rating back in 2017.

It comes as standard with six airbags, auto emergency braking, forward collision warning, lane departure warning, blind spot monitoring, cruise control, a reversing camera, front and rear parking sensors, and a tyre pressure monitor. 

It lacks some of the more modern active driver aids that are offered as standard in rivals, like an active lane-keeping system that helps ensure the vehicle doesn’t cross line markings. The Koleos makes do with an audible warning that, oddly, sounds like a whoopie cushion when activated.

The cruise control is not adaptive, instead it’s the old school version that doesn’t detect vehicles ahead and lower its speed accordingly. 

Having more up-to-date safety gear would improve the Koleos’ appeal.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. Unlimited km in the warranty would be welcome.

Service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped price servicing covers the first five scheduled services for MY24 and later vehicle models (up to 5 years/75,000km – whichever occurs first) – at a flat price of $469 for each service.

Isuzu Ute Australia has a nationwide network of more than 160 dealer sites.

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.
