Isuzu MU-X vs Renault Duster

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.

The Renault Duster 4x4 Evolution (manual) is a driver’s car. Lots of fun for day-to-day duties and a real visceral experience if you like to have a few laughs on loose-dirt and gravel tracks. And it’s adequately capable for off-roading adventures. It also has more than its fair share of cheeky charm.

Obviously it’s not anywhere near the most capable off-road vehicle available. That’s not what it’s intended to be. But it’s one of the most fun to drive on- and off-road.

And for $36,490 (excluding on-road costs), you’ll still have cash enough for a set of all-terrain tyres and some accessories.

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.

From the outside, the Duster 4x4 Evolution has that special ‘something’ that draws your eye. It’s unassuming, yet somehow eye-catching.

It’s a chunky little AWD with ‘Renault’ across the front grille and its raised stance gives the Duster a rugged presence.

Hard angles and nifty touches, such as the concealed rear door handles on the C-pillar, add to its funky exterior.

The Duster’s interior continues the minimalist theme with hard plastic surfaces everywhere – including the dash and door armrests – and black and grey cloth upholstery, all amid a neat but uncluttered layout.

The 10.1-inch multimedia touchscreen , angled slightly towards the driver, dominates up front and caps off what is an unpretentious, functional cabin.

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.

The interior in Evolution trim matches the Duster’s no-nonsense adventure-focussed approach. It’s spartan but user-friendly.

The front seats are manually adjustable and the cloth upholstery looks like it’s hard-wearing and likely able to cope with the utter messiness of life.

I had trouble getting my phone to work via the 10.1-inch multimedia unit, but otherwise I have few complaints about the system as it’s easy enough to operate. There’s a wireless-charging pad below the screen. There are also two USB-C charging ports up front and two for rear-seat passengers, as well as two 12-volt sockets one in the front and another in the rear cargo area.

There is a mix of physical buttons and on-screen controls to operate various in-cabin functions, such as air-con.

For storage there is a glove box, a deep centre console, two cupholders, and a small shelf for your pocket clutter.

The second-row seats are roomy enough for two adults or three teens across the row and while passengers there have access to two USB-C charging ports and air vents, there’s no fold-down centre armrest.

The rear cargo area is accessed via a manual tailgate and is claimed to offer 358 litres of cargo volume when the rear seat is in use and 1424 litres when the second-row seat is stowed away.

Payload in the Duster Evolution 4x4 is listed as 503kg. The cargo area has a light, cargo hooks and a 12V socket. This Duster has a 215/70 R16 spare stored underfloor.

The 2026 Renault Duster is available as a 4x2 (automatic) or 4x4 (with a six-speed manual) in two trim levels – the Evolution and the Techno – with a choice of a turbocharged 1.3-litre four-cylinder engine (for the 4x2) or a turbocharged 1.2-litre mild-hybrid three-cylinder engine (for the 4x4).

Our test vehicle, the 4x4 Evolution, has a manufacturer suggested retail price of $36,490, excluding on-road costs.

Standard features include a 10.1-inch multimedia touchscreen (with wireless Apple CarPlay and Android Auto), a wireless smartphone charger, 7.0-inch digital instrument cluster, six-speaker Arkamys sound system, dual-zone climate control, 17-inch alloy wheels, Continental Cross Contact 215/65 R17 tyres and a 215/70 R16 spare.

There’s also a range of accessories available including Rhino Rack and Thule storage platforms and racks.

Exterior paint choices include the no extra cost 'Solid White' as well as 'Khaki Green', 'Pearlescent Black', 'Terracotta', 'Cedar Green', 'Sandstone' and 'Shadow Grey'. All metallic or premium paint adds $750 to the Duster’s price.

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 Duster 4x4 Evolution has a 1.2-litre three-cylinder turbo-petrol engine with a 48V mild-hybrid system (producing 96kW at 4500rpm and 230Nm at 2250rpm) matched to a six-speed manual gearbox.

As I said earlier, a new small 4x4 SUV with off-road capability and a manual gearbox is refreshing.

This Duster has an all-wheel drive system and the little 1422kg SUV can do the 0-100km/h sprint in a claimed 11.94 seconds.

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.

Official combined cycle (urban/extra-urban) fuel consumption is 5.7L/100km.

On test, we recorded 6.7L/100km but we did do a half-day of light off-roading.

This Duster 4x4 has a 55-litre fuel tank so, going by that on-test fuel figure, you could reasonably expect a driving range of about 820km out of a full tank.

The turbocharged 1.2-litre mild-hybrid three-cylinder engine requires 95 RON premium unleaded petrol.

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.

My kids are learning to drive in a manual because I reckon being able to drive a manual vehicle remains an important skill to have. I only own manual cars at this point in time and it’s nice to see new cars with manual gearboxes haven’t been done away with just yet.

This all-wheel drive adventure machine is light at 1422kg and punchy, working through a turbocharged 1.2-litre mild-hybrid three-cylinder engine (producing 96kW at 4500rpm and 230Nm at 2250rpm) and a six-speed manual gearbox.

It’s sporty, with precise steering, crisp throttle response and nicely controlled ride and handling. And it’s a whole lot of fun to drive on sealed surfaces.

Throwing it around corners at (legal) speed is a barrel of laughs and driving on fast loose-dirt tracks is damn good for rally-style hilarity, all with the gruff backing track of this little AWD’s tractable petrol engine. Driving the 4345mm long, 2069mm wide and 1650mm high Duster feels like you’re punching a go-kart around a track, in a good way.

The Duster’s suspension deserves a mention here because this package, including an independent multi-link set-up at the rear, yields a firm but well-balanced overall feel.

Its tight turning circle makes it supremely easy to accomplish quick manoeuvres without fuss and it’s also a cinch to park.

Visibility from the driver’s seat is somewhat reduced through different angles to the rear and back along the vehicle’s side, but you get used to that. It doesn’t help that the camera view is muddy looking on the screen.

Those niggles aside, did I mention it’s fun to drive?

It’s not too shabby in low-speed off-road scenarios, either. The Duster is similar to Subaru’s Crosstrek and XV or the Jimny, in that this Renault’s intended use is not as a hardcore rock-crawling beast, it’s not engineered for that sort of thing.

The Duster's all-wheel drive system is well calibrated and quietly effective at detecting wheel-slip and delivering a smooth response. Driven with care, this AWD SUV is capable of off-roading at a level that will surprise some.

It has a 4x4 terrain control system with five modes – 'Auto', 'Eco', 'Mud & sand', 'Snow' and 'Off-road' – as well as a hill descent control system. None of these are engineered to turn the Duster into an off-highway mongrel but they ensure it's able to cope with mild to less-mild off-roading.

The Duster’s ground clearance (212mm) and off-road angles (31-degree approach and 36-degree departure) make it better suited to tackling off-road terrain of the light-to-moderate variety rather than door-sill deep mud holes and the like.

For reference, the Suzuki Jimny has 210mm of ground clearance and approach and departure angles of 37 and 49 degrees. The Crosstrek has 220mm of ground clearance, and approach and departure angles in the off-road-focussed Wilderness of 23.5 and 25.5 degrees.

But it’s still very capable if driven with consideration and well within the limits of its physical dimensions and off-road traction control.

Light off-roading (well-maintained gravel roads and dirt tracks in dry conditions) is fine because that’s well within the Duster’s capabilities and it results in little to no wear and tear on the vehicle.

While the Duster can handle short bursts on firm-packed sand (which I test here), sand-driving puts extra stress on any vehicle, and AWDs don’t have a lot of ground clearance, so they’re prone to bellying out on tall crests in between deeper wheel ruts on a beach.

My advice? Avoid anything beyond a well-maintained dirt track in dry weather and don’t take on any ‘4WD/ high ground clearance only' tracks, prolonged sand-driving or rock-crawling. Anything more rigorous than that and you risk damage to the vehicle’s underbody at a minimum, and mechanical damage and personal injury at worst. You’ve been warned.

The Duster’s off-road capabilities could easily be further enhanced with a set of decent light truck all-terrain tyres but, be aware, even aggressive rubber won’t turn it into a gung-ho off-roader.

For the record, it has unbraked trailer towing capacity of 750kg and braked towing capacity of 1500kg. Maximum towball download is listed as 75kg.

A bonus for Duster owners is that it can be kitted out for adventure via either Renault’s range of accessories – including all-weather floor mats, roof box, roof racks etc – or through Australia’s aftermarket industry.

The Renault Duster 4x4 Evolution (manual) does not have an ANCAP safety rating because it has not been tested.

Standard safety gear includes six airbags, AEB, driver attention alert, lane-keep assist, lane departure warning, traffic sign recognition, rear parking sensors and a reversing camera.

The Duster range does not have adaptive cruise control (only regular ol’ cruise control) or rear cross-traffic alert.

The rear seat has two ISOFIX points and three top-tether child-seat anchorage points.

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.

A five-year/unlimited-kilometre warranty with five years of roadside assistance applies to the Duster. That's average for the mainstream market.

Servicing appointments are set at 12 months/30,000km intervals, whichever occurs soonest.

Capped price servicing applies to the first five services with a total cost calculated at $2475 for the all-wheel Duster, with an average per-service cost of $495, which is getting up there for a car in this price bracket.

Renault has more than 70 dealerships across Australia.
