Isuzu MU-X vs Suzuki Fronx

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.

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.

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

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.

‘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 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.

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.

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 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 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.

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.

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.

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. 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.

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.
