Renault Arkana vs Isuzu MU-X

What's the difference?

The Arkana is a stylish alternative in a sea of same-same compact SUVs. It's relatively well equipped and has some hidden gems in its ownership and running costs that elevate it above some of the competition.

It’s not a bad thing to steer, either, but the lurchy dual-clutch could be a deal breaker for some.

The sweet spot is the Techno, which misses out on the Esprit Alpine’s special touches but represents the most bang for your buck.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

The MU-X has always had plenty of appeal as a daily driver – dependable, not dynamic – and it’s a proven 4WD wagon.

Some people don't like the noisy, sluggish engine, but I don't mind it because it delivers off-road.

There was already a lot to like about the seven-seater wagon in terms of its off-road capability, driver-assist tech, standard features, and simple all-round driveability, and the X-Terrain – which encompasses all of that AND adds some polish to the mix – is an impressive top-shelf addition to the MU-X line-up. Even if it's so pricey...

This update isn’t a massive overhaul of the Arkana, rather its “refreshing and enhancing” what was already there according to Renault Australia.

And this remains true with the car’s styling. Not much has changed on the outside except for a few minor garnishes and flourishes, especially on the Esprit Alpine variant.

The coupe styling isn’t for everyone. It’s more popular in Europe than Australia but if you want to stand out from the crowd it’s a good place to start.

The Arkana has curves in all the right places and its little grille made up of little Renault badge diamonds is a welcome addition in a world of wide mouth front ends. The C-shaped LED headlights and a large Renault badge add a bit of pop to its look.

The pinched rear end has LED lighting that runs from the tail-lights to the centre badge and Arkana is spelled out in big, bold letters.

The Esprit Alpine stands out with gunmetal highlights on the front bumper and the front and rear skid plates in the same colour. It also adds a Esprit Alpine badge below the side mirror and front door sill plates.

The Esprit Alpine has 'Tricolour' stitching in red, white and blue on the door trim and steering wheel, which is complemented by blue contrast stitching on the gear shifter, seats and centre console.

Cabin quality is variable. There are some nice feeling materials used on the dash and on the door trims but below eye level there are lots of hard wearing plastics. A big slab of faux wood running along the dashboard doesn’t feel as high-quality as you would like. The quality drops a bit in the back row, which is where carmakers often try to cut costs.

Solid white is the only no cost paint colour, but it is not available on the Esprit Alpine. Metallic white, blue, black, grey and red cost $750.

Buyers can also option a black roof for a two-tone look for $600.

As I’ve said before, the MU-X has never been particularly exciting or boring in terms of design, just comfortably adopting a low-key, middle-of-the-road type design – sales gold, in other words.

But the X-Terrain has distinctive ‘X’ branding here and there – inside and out – and that adds a subtle class to this variant.

The X-Terrain is 4860mm long (with a 2855mm wheelbase), 1870mm wide (excluding mirrors), 1825mm high and has a listed kerb weight of 2195kg.

It has a wheel track of 1570mm and an 11.6m turning circle. 

Our test vehicle has the exclusive X-Terrain paint – slate grey metallic – which matches well with the X badging, bigger grille design, new headlights, three-tier LED tail-lights, and redesigned wheels.

The interior strikes a stylish note as well with red stitching on the dash, centre console and leather-accented seat trim.

The Arkana isn’t a family SUV, but rather is pitched at younger couples and empty nesters. 

Up front there is great forward vision with a higher seating position than hatchbacks and sedans. Electronically adjustable seats and a manually moveable steering wheel means there’s a good seating position for pretty much everyone.

The seats are comfy and the multimedia screen and climate controls are easy to reach. The centre console has a wireless device charger, two USB-A charging ports and a 12-volt socket to keep various devices juiced up. 

Two cupholders take up most of the space with minimal storage space leftover. There are decent sized storage bins in the doors and a little net in the passenger seats footwell to stop small items rolling around. 

Back seat passengers have their own air con vents and USB charging ports, which is a welcome addition.

In the rear pew is where the Arkana’s stylish coupe-like design dents its practicality. The sloping roof shrinks the windows and reduces headroom, which makes it feel a bit gloomy compared to more boxy-shaped SUVs that makes it no-no for smaller kids.

The boot is a decent size, but it’s longer and lower than other SUVs, which is the price you pay for looking good. 

The interior has a pleasant, familiar and practical feel about it and this is an easy space in which to swiftly become comfortable. 

Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C and 12V up front, and USB-A for the second row.

Storage places include recesses for your everyday carry gear, a suitably deep 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 cupholders either side of the third row in the MU-X for passengers riding back there.

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

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

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 folded.

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 X-Terrain 3.0L 4x4 is priced at $74,400 before on-road costs, or $73,990 drive-away for now.

Standard features include a 9.0-inch multimedia touchscreen system with sat-nav, wireless Apple CarPlay and Android Auto, an eight-speaker sound system, eight-way power-adjustable driver’s seat (four-way power-adjustable front passenger seat), remote engine start, smart entry and start, and 20-inch machined-alloy gloss-black wheels on 265/60R20 Bridgestone 684II HT tyres.

As part of the X-Terrain package, it has XT badging in the grille mesh, on fender and tailgate, leather-accented seats with red stitching, gloss-black fender flares and fender garnish.

It also has 265/50R20 highway terrain tyres, red ambient interior lighting with footwell lamp 360-degree, surround-view monitor, and a red-themed 7.0-inch multi-information-display.

Exterior paint jobs on the MU-X X-Terrain include four achromatic finishes: Moonstone White pearl, Mercury Silver metallic, Basalt Black mica and the new X-Terrain exclusive colour, Slate Grey metallic. 

All premium paints (pearl, metallic and mica) cost an extra $695. 

The Arkana keeps the 1.3-litre four-cylinder turbocharged petrol engine from before. It makes 115kW and 262Nm and is paired with a seven-speed dual-clutch auto that drives the front wheels. 

That’s plenty of grunt for a car this size, but it’s let down by a glitchy transmission that hesitates a lot at lower speeds and doesn’t do its best work when asked to hustle, either.

The MU-X has a 3.0-litre four-cylinder turbo-diesel engine, producing 140kW and 450Nm and it’s matched to a six-speed auto.

These form part of a proven powertrain and while the MU-X may not be the most dynamic vehicle to drive – it’s acceleration is sluggish rather than punchy – it has a real tractability that nullifies any other niggles.

It has part-time 4WD, with high- and low-range as well as various drive modes, rough terrain mode, and a rear diff lock.

Efficiency is the name of the game with the Arkana’s little turbo engine. The French brand claims it drinks 5.9L/100km on the combined (urban/extra-urban) cycle but we averaged 7.5L/100km on our circa two-hour country road drive according to the trip computer.

The higher speed twisting and turning country roads we drove on aren’t conducive to low fuel use, though.

It has a 50-litre fuel tank and only requires cheaper 91 RON petrol, which is rare for little turbo engines that usually have premium tastes.

Official fuel consumption for this MU-X is 8.3L/100km and that's on a combined cycle. 

On this test I recorded 10.2L/100km. I did a lot of high and low-range four-wheel driving, so that fuel consumption is not too shabby.

The MU-X has an 80-litre fuel tank, so going by my on-test fuel consumption figures you could reasonably expect a driving range of about 784km from a full tank. 

The Arkana is a bit of a mixed bag on the road. Its engine is a nice little unit but the dual-clutch auto deflates the drive experience.

At lower speeds it hesitates and then gives too much oomph all at once, which can result in some wheel spin. It means you need to be mindful at T-intersections and when turning across traffic and feather the pedals. 

This is a symptom of most dual-clutch autos but the Arkana’s is less sophisticated than say ones fitted to Volkswagens, and the Arkana doesn’t have the meaty power and torque bands of performance cars. A conventional torque converter auto would suit it better.

The Arkana does some of its best work at higher speeds, where the dual-clutch is more decisive and it's an admirable highway cruiser. 

It isn’t a bad operator through the bends where it exerts excellent body control to minimise rolling. This is complemented by nice steering that is well weighted and accurate. Pedal feel is excellent with no woody or doughy feel to them.

The suspension is on the firmer side and you’ll feel some harsh bumps, especially over consistent smaller ones that it will crash over.

Its rear torsion beam suspension set-up is less sophisticated than the multilink arrangements found in an increasing number of competitors in the segment.

Road noise is noticeable at higher speeds. There's a fair bit of wind noise, too, but it was an especially windy day on our test drive.

The Arkana isn’t a sports car but is a stylish SUV for punting around town and facilitating weekend getaways, but there are other compact players that answer this brief better.

In previous tests, the MU-X has been fine on road and more than adequate on gravel, dirt tracks, and during low-range 4WDing. But it’s been a jarring, skippy ride on irregular surfaces rather than as composed as it could – and should – have been. The culprit? Firm suspension, over-inflated tyres, too-tight trousers, who knows?

The good news is it seems like Isuzu has ironed out any issues in the suspension, minor or otherwise, because the MU-X is now is a lot better in terms of ride and handling than ever before. 

Off-road, the MU-X has always been a proven combination of its 3.0-litre, four-cylinder turbo-diesel engine, clever six-speed automatic transmission, and an off-road traction control system that's been increasingly well recalibrated through a number of generations. 

The engine is tractable and gruff, it has plenty of grunt and, as long as you're not driving like a complete hoon, you can usually get through most obstacles without a lot of fuss.

It's this mix of mechanicals and driver-assist tech that make the MU-X such an effective 4WD package. And there are a number of reasons for that. 

For one, that engine delivers plenty of torque down low and in the mid-range torque and that's crucial for four-wheel driving. 

And another thing, Rough Terrain Mode – like a beefed-up and fine-tuned off-road traction control – proves very effective because it punches torque to the wheel with the most traction – while wheel spin on tyres that aren't touching dirt is minimised – and that way it keeps the vehicle moving through obstacles with safe and controlled momentum. 

As I’ve noted before though, Rough Terrain Mode is not a magic all-conquering solution, but it is another handy addition to the MU-X’s off-road toolbox.

And the MU-X also has a rear diff lock to back you up – and that's another valuable component. 

The MU-X has approach, departure and ramp-over angles of 29.2, 26.4 and 23.1 respectively.

A listed 235mm of ground clearance is about standard for this kind of wagon but, as I’ve said before, it seems vulnerable in the underbody, side steps and its plastic mud guards. So the underbody may touch dirt, depending on how challenging the terrain is. 

Wading depth is listed as 800mm.

But, as always, with focused driving, you’ll have lots of fun and you'll minimise any superficial damage or scuff marks to the MU-X.

The MU-X has plenty of potential as a touring platform, but, if you’re planning to do any off-roading beyond well-maintained tracks, then get rid of its road-biased tyres and replace them with all-terrain tyres.

The showroom-standard tyres on this MU-X – 265/50R20 Bridgestone Dueler HTs – are okay, but not really up to scratch if tough 4WDing is what you’re keen to do. I’d prefer an 18-inch wheel and tyre package with decent all-terrains.

The MU-X has a full-sized underslung spare and in terms of packability, the MU-X X-Terrain has a listed payload of 605kg, GVM is 2800kg and GCM is 5900kg.

If you are considering using your MUX as a tow vehicle, it's handy to know that it can legally tow 750kg (unbraked) and 3500kg (braked), which is the standard for large four-wheel-drive wagons. 

Be aware though that, as with any other vehicles, once you're towing anywhere near the maximum weight, your payload is greatly reduced.

The MU-X has the maximum five-star ANCAP safety rating from testing in July 2022.

Standard safety features include eight airbags (dual front, dual seat side, dual full-length curtain, front knee and centre, far-side), and a comprehensive suite of driver-assist tech including forward collision warning, adaptive cruise control, lane departure warning, and a tyre-pressure monitoring system.

New gear onboard includes new hardware for the auto emergency braking ( AEB), like improved vehicle detection, periphery and depth perception, new digital reversing camera with a hydrophobic coating to prevent water and dirt build-up (better visibility off-road), new rear cross traffic brake (detects and reacts to approaching vehicles, cyclists, and pedestrians when reversing), as well as updated lane-keep assist ( smoother steering correction).

There is one part of Renault’s ownership credentials that others can’t match.

Its service intervals are every 12 months and a whopping 30,000km, which is double the industry norm of 15,000km. 

If you need to do big kays such as a sales rep or rideshare driver might this will be extremely important.

Five years or 150,000km of capped price servicing visits costs $2385, which is one the expensive side compared to Honda, Hyundai and Toyota but is in the ballpark of similar-sized Kias and Volkswagens.

Renault covers the Arkana with a five year/unlimited km warranty - par for the course in the mainstream market - and five years of roadside assistance.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. That warranty is okay in terms of years, but unlimited kilometres 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 24MY and later vehicle models (up to five years/75,000km, whichever occurs first) – at a cost of $469 for each service.
