Isuzu MU-X vs Suzuki Fronx

What's the difference?

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...

If you’re considering a small car, particularly if an SUV is the goal, a Suzuki should in most cases be on the shopping list. Back-to-basics motoring is key to the brand’s identity. Its most popular model is a tiny ladder-frame 4X4, for example. Hi Jimny.

The Fronx doesn’t break new ground in any practical sense, but it does come in with a decent price and list of features that should sway plenty of small-car fans in the showroom.

It’s decent to look at, comfortable for the segment, and easy to get used to and drive. The numerical rating on this review betrays just how likeable the car is.

It’s not extremely refined and it starts to lose its dynamic shine on rough roads, but in an urban setting the Fronx should excel.

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.

‘Fronx’ as a name doesn’t exactly scream ‘cute’, but the little SUV has a pretty classically Suzuki design. This is not a complaint at all.

The Fronx is 3995mm long, 1765mm wide and 1550mm tall, but despite its diminutive dimensions the brand has opted to lean into a ‘coupe’ style with a sloping roofline that creates a relatively sporty look, especially for something with a two-digit power figure.

So while some of Suzuki’s designs have been divisive in Australia (Ignis, anyone?) the Fronx takes a slightly more conservative approach by leaning into more design trends than just the coupe-back SUV shape. 

For example, its tail-lights span the width of the tailgate rather than simply flanking the boot as was standard for decades.

The LED daytime running lights at the front are also arranged in a slim, high-up position with a set of headlights below.

Inside is arguably more conservative than out, as the Fronx goes with a fairly standard formula in terms of its layout, with few premium materials (the synthetic leather on the seats feels cheap for example) or adventurous design elements to be found.

But that’s not such a bad thing.

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.

Because for all the conservative, even outdated, styling in the cabin, the fact is it’ll be refreshingly familiar to someone who’s getting out of a car from perhaps even before the year 2000.

Suzuki’s place at the budget end of the new-car market means its customers are likely either quite young and buying their first new car, or relatively old and looking for a cheap, rarely used runabout as the ‘last car’.

For the former, a lack of techy distractions is paramount. For the latter, ease of use wins over cutting-edge tech in most cases. Which is why it’s probably okay that the Fronx’s multimedia touchscreen and software wouldn’t feel out of place almost a decade ago.

It can be a tad fiddly to use at speed, but it’s still more straightforward than the ‘iPad-like’ systems Tesla has made popular, and there are physical controls for important functions like climate control.

There’s also a row of ever-present haptic buttons for volume controls and navigation shortcuts.

The ergonomics of the interior are quite basic, but there are no red flags in terms of visibility, reach, or placement. 

The head-up display is a bonus, but the physical dials on the dash rather than a digital driver display are clear enough, despite again feeling nabbed from a time before head-up displays even existed. 

Space for the front passengers is decent, it’s not cavernous but it’s far from cramped. Elbow rests and seating positions allow for a relaxed ride.

The back seat is a slightly less comfortable place, but at 178cm I can sit behind my own seating position without my knees touching the seat in front, and my head has just enough space above to accommodate the top of a mullet.

Behind that, luggage capacity in the boot is 304 litres, or 605 litres with the rear 60/40 split seats folded.

There’s also no space-saver spare tyre, just a repair kit as standard.

There’s only one variant of the Fronx, and it lands at $28,990 before on-road costs. It’s also relatively stacked when it comes to features, and Suzuki is even working on a sub-$30K drive-away offer for its on-sale date in September this year. We’d expect that means about $29,990 DA, though that’s to be confirmed down the track.

For something at that price point, features aren’t lacking. While things like wireless phone charging and wireless Android Auto and Apple CarPlay have become almost expected for even entry-level cars in Australia, the Fronx also features heated synthetic leather seats and a leather steering wheel.

It’s the first Suzuki in Australia to feature a head-up display, and there’s also a standard surround-view parking display thanks to a set of cameras.

The Fronx’s 9.0-inch multimedia touchscreen is joined by a small 4.2-inch driver display nestled between physical dials for the speedometer and tachometer. Exterior lighting is LED front and rear, with auto headlights and manual levelling.

The only extra-cost option for the Fronx is a choice of ‘premium’ single- or two-tone paint - Arctic White Pearl is the standard no-cost colour. Single-tone paint is $745 extra, while two-tone options are $1345, which is a lot pricier than many premium paint options in the market.

The Fronx comes in at the same price as a mid-to-high spec Hyundai Venue, Kia Stonic or Chery Tiggo 4, but some rivals like the Mazda CX-3 or Toyota Yaris Cross (with its Hybrid drivetrain) are more expensive even in their lower variants.

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.

The Fronx is powered by a 1.5-litre four-cylinder engine with mild-hybrid assistance, driving the front wheels via a six-speed automatic transmission. 

Its outputs are quoted at 76kW and 137Nm, not exactly high-grade stuff and part of the reason the Fronx feels like it takes more than 10 seconds to hit 100km/h.

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. 

Suzuki claims fuel consumption at 4.9L/100km. With its 37-litre fuel tank, the Fronx should be able to manage more than 600km on a single tank, though theoretically its maximum range given its claimed fuel efficiency is 755km.

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.

How you plan to use the Fronx will make a big difference in whether what you’re about to read is a good thing or not. 

The Fronx is a light SUV for a start, so expecting brilliant handling, effortless acceleration and a dead-quiet cabin is going to mean you’re disappointed.

But if you want something easy, engaging and fun, the Fronx might work for you.

Our brief test loop wasn’t entirely indicative of what the Fronx is likely to face day-to-day. With limited time and no preset drive program, the roads within a 20-or-so minute drive of Nagambie, Victoria had to suffice.

The Fronx fared well on the average road, it turned out, with the 1064kg Suzuki managing to feel planted enough to hurl along 100km/h back-roads without complaints. It rides on the same platform used recently by the Suzuki Baleno, something I’ll admit to not having driven.

The rougher roads didn’t faze the light SUV too much, though consistently uneven surfaces made it feel unsettled in some cornering.

Its steering and suspension give enough feedback to make the right inputs easily, though the nature of its light weight and minimal accoutrement in terms of driver assistance make the Fronx feel very rudimentary from the driver’s seat.

At low speeds around the centre of town, the Fronx manages the state’s terrible roads well, though taking off from intersections can be laborious. Much like overtaking, the drivetrain will complain.

And don’t expect its mild hybrid system to do a lot in the way of hard work - or any work at all, really. You could take the hybrid badge off the car, let someone have a drive, and they’d be none the wiser.

From the limited observations on the launch, the Fronx would feel best at home in suburbia or a metropolitan centre more so than on the Hume Highway or the towns dotted alongside it.

Essentially, this is not a refined road trip car for the highway, but its no-fuss approach to getting around means you shouldn’t be surprised if you start seeing them in the car parks at universities or bowls clubs.

A big part of many buyers’ decisions about a new car is safety, and the Fronx is pretty basic on this front.

Six airbags cover front and sides for the front passengers, and there are curtains down the sides of the car, but there’s no front centre airbag and no ANCAP rating has been applied to the Fronx as yet.

In terms of active safety, the Fronx has listed among its standard features auto emergency braking (AEB), ABS and brake assist, lane departure warning, hill hold control, weaving alert, blind spot monitoring, traffic sign recognition, rear cross traffic alert and a surround-view parking camera with front and rear sensors.

There are also outboard ISOFIX seat fastenings in the second row.

The only safety system that activated during the test was a lane departure warning, but only when (under normal conditions) it would have been necessary as the car approached the road’s centre line.

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.

Suzuki has a five-year, unlimited kilometre warranty for its new cars, which is a little behind the curve compared to many budget-friendly brands these days. 

Suzuki does have a five-year servicing schedule, with intervals every 12 months or 15,000km, whichever comes first. Total cost is $2005 over the five years, with services averaging $401, which is not particularly cheap.
