What's the difference?
Sometimes it really is all a matter of timing.
GWM was always going to offer up the plug-in hybrid version of its Tank 300 4X4, but for it to arrive in showrooms right now must be being looked on as some kind of blessing at GWM HQ.
Consider the circumstances: The Tank 300 Hi4-T PHEV (to give it its full name) not only saves fuel by making use of plug-in hybrid tech, but the fossil stuff it does use is petrol, not diesel with that fuel’s buck-a-litre cost penalty right now.
And with the planet on a knife’s edge waiting for the next increase in brinkmanship from those referred to as our world leaders, overseas travel has never seemed sketchier to the average Aussie. Which is when keeping it local and hitting the outback in a four-wheel drive suddenly looks really, really good. Except for the cost of fuel, that is, which is where we circle back to square one.
All of which means the GWM Tank 300 Plug-in hybrid concept could not really have come at a better time. But does the reality match the promise?
KGM (formerly SsangYong) has revised its Musso range for 2026 with some new features and revised styling throughout the Australian line-up, as well as a name-change for this grade: the Advance which used to be the Adventure.
The updated Musso is a dual-cab 4WD ute with high and low-range gearing, an auto-locking rear differential and 3.5-tonne towing capacity, and all for under $50,000.
And with the optional XLV (extra long vehicle/version) pack, which our test vehicle has, it gets a longer wheelbase (110mm extra), a 300mm longer tub and 90kg of extra payload over the standard Musso (880kg rather than 790kg).
So, is the Musso an affordable alternative to the likes of Toyota HiLux and Ford Ranger?
There’s a lot to like here. The GWM Tank 300 in any of its forms is a competent vehicle from the helm and backs up its off-road claims with real ability. The ride quality, in particular, is a highlight, and it’s a good size for couples or young families. Its value for money is also quite brilliant.
Add this plug-in hybrid driveline to the mix and the performance is quite astounding, while the petrol engine and EV potential have arrived at a critical point in history where such things carry more weight than ever before. It remains to be seen what happens globally and what effect that has on fuel prices, specifically the price gap between petrol and diesel. There’s also the question of what happens electronically when you dunk the Tank into Nolan’s Brook on the track to Cape York. But for now, this is a car whose time appears to have come.
But while the overall concept deserves praise, there’s still some work required in terms of the way the car drives and in its attempts at keeping its occupants safe. The calibration of both the throttle response and some of the driver aids is, frankly, in need of some final polish. And though it sounds odd, the Tank 300 would be a better thing to live with if GWM ditched the contentious driver aids and took the points hit on its ANCAP rating. Even better would be to stick with the tech but refine it to the point where it works in the background and not as an irritant.
The KGM Musso Advance is a large 4WD ute offering a decent amount of appeal for the price and it makes a lot of sense in XLV form.
It’s generally nice to drive, it’s comfortable and capable for a ute and – as with the Rexton – the Musso is another clear sign that KGM continues to improve its vehicles, albeit incrementally in some cases, in terms of quality and functionality.
Derivative is a strong word, but from most angles there’s a little bit of something else in the Tank 300’s exterior. We can easily see a bit of Suzuki Jimny in profile, and a dash of new Ford Bronco in the lights and grille. And if you squint there’s a blob of Jeep Wrangler in the wheel-arch extensions.
Which should mean it’s just a mash-up. Yet somehow, it isn’t, and the Tank has its own vibe.
Inside, that vibe suddenly becomes a bit overdone, and the plastic garnish above the glove box, in particular, looks like it will date pretty quickly (if it hasn't already). There's also a lot going on in here; this is a busy place and even the gear selector looks like a prop form the Star Wars franchise.
The Musso is based on its SUV stablemate, the Rexton. It’s a body-on-frame 4WD ute, available only as a dual-cab, and its appearance is inoffensively pleasant.
Styling changes to the Advance include a black grille, black 18-inch alloy wheels, HID headlights (on short and XLV grades), and rear privacy tint.
It also has a black leather-look interior with black leather-look seats.
The Musso’s interior offers plenty of space for the driver and passengers and is neat and well laid out.
Build quality and fit and finish are impressive with a mix of durable plastic and soft-touch surfaces throughout including a leather steering wheel and leather-look seats in the Advance.
While GWM is by no means the worst offender, we still reckon the Tank’s interior would be better without such a degree of reliance of touchscreens and menu-driven functionality. While it’s obvious that there’s a lot going on in the cabin, it still seems odd that important functions such as shifting from conventional hybrid mode to EV mode would require a dive through the on-screen menus when a simple switch would be faster, easier and simpler.
And even when GWM has provided switches, the end result is muddy. Take the volume controls for an example. There’s no central volume knob accessible by both front seat occupants, so you rely on the steering wheel mounted up and down buttons to change the volume. Except they’re not marked as volume controls in any specific way. Okay, if you know, you know. But if you don’t know, you’ve just missed the news headlines.
Overall, it's disappointing. And I resent the fact that GWM (or anybody else) thinks it’s okay for me to have to learn to operate a car all over again. The dashboard is also full of tiny symbols and lettering making things difficult to decipher if you normally wear glasses to read, but not to drive.
We’ll take issue with the indicator stalk, too, which has an indistinct feel when trying to discern whether you turned the indicators on for an intersection, or just tipped them on for three flashes for a lane change. And if you have accidentally gone too far and they’re still flashing away merrily after the lane change, turning them off manually is a lottery that might see you succeed, or mistakenly turn on the other side flashers.
The rest is better with proper buttons for the various off-road drive modes, diff locks and hill holder. There’s even an analogue clock for some real nostalgia. You’ll also find a single USB-A and USB-C charge port in the dash, and a pair of cupholders buried deep in the centre console which also has a lid and sliding drawer.
It’s obvious that this is a smaller vehicle than some, and the four-door layout dictates shorter doors. But that doesn’t alter the fact that the driver’s seat slides back a few centimetres every time you shut the car down. The trouble with that if you’re tall, is that the seat is now tucked back in behind the B-pillar, meaning you have to climb out and around it to exit the car. Perhaps you can switch off this slide-back function, but I didn’t have the spare hour to troll through the menus to do so. Oh, and there should be a driver’s grab handle on the A-pillar, too. There isn’t.
The rear seat is better with an adjustable backrest that provides proper comfort, and leg and knee room that hides the 300’s smaller dimensions well. There’s lots of glass and light and a pair of USB charge points. You also get a pair of rear reading lights and central vents, but no climate controls.
Even the cargo area is a decent size with the five seats in place (360 litres, up to 1520L with 60/40 rear seats lowered) but the under-floor storage space has been consumed by the hybrid battery, meaning the jack and tools and charging cable live in the cargo area and the spare tyre is bolted to the tailgate.
The single-piece tailgate is hinged at the side, and needs a fair bit of real estate to be swung open fully.
The Tank features vehicle-to-load capability, too, which means you can operate your power tools using the vehicle as the power source, and there’s a 220-volt socket in the luggage area to do just that. But when camping, too, this feature can also power induction cookers, microwaves, and all the other stuff you probably should have left at home. And if the hybrid battery runs out of charge, the Tank can run its petrol engine to act as a generator (your camping neighbours are going to love that).
The real gadget freaks out there can also download the Tank app which allows you to operate functions such as power windows, climate control, seat heaters, central locking and check your charging status all from the comfort of your smartphone. You can also use this functionality to flash the hazard lights to help spot your Tank from everybody else’s in the carpark.
There is the expected array of storage spots (glove box, door pockets etc), cupholders (two to the rear of the auto shifter) and charge points (two USB-C ports and a 12-volt plug point for driver and front passenger).
The seats are comfortable and supportive and, in general, KGM has maximised space in the cabin, yielding plenty of shoulder and legroom for driver and passengers.
The 12.3-inch touchscreen multimedia system works reasonably well although you do have to cycle through numerous menus and sub-menus to change some settings and I did have to try several times to pair my phone to it, so overall functionality is clunky.
Rear-seat passengers have access to directional air vents, but there are smart-device charge points.
The tub size is as follows: 1600mm long in the XLV (1300mm in the standard Musso), 1570mm wide (1100mm between wheel-arches) and 570mm deep. The tub has a plastic tub liner and four tie-down points.
For a direct comparison of dimensions: the standard Musso is 5095mm long with a 3100mm wheelbase while the XLV is 5405mm with a 3210mm wheelbase; the standard Musso is 1950mm wide and 1870mm high (the XLV is 1885mm). For reference, the Ford Ranger XLT dual-cab ute is 5406mm long (including rear bumper and tow bar receiver) with a 3270mm wheelbase.
The difference in dimensions between a standard Musso and the XLV version also means a difference in off-road angles so approach is 22.8° / 25° (XLV), departure is 23.4° / 20° (XLV) and rampover is 23° / 20° (XLV).
Minimum ground clearance is 215mm in a standard Musso and 220mm in the XLV, so the Musso XLV does stand taller off the ground than its regular stablemate.
Kerb weight is listed as 2090kg for the standard Musso and 2100kg for the XLV. Turning circle is 11.8m for the standard Musso and 12.2m for the XLV.
The Tank 300 PHEV is available in two trim levels, starting with the Lux at $55,990 drive-away. That gets you 18-inch alloy wheels, roof rails and side steps and, perhaps a little surprisingly, a sunroof.
There’s also power folding mirrors, keyless entry and start, paddle shifters, adaptive cruise-control and a rear differential lock.
Inside, there are leather accents for the seats, a pair of 12.3-inch multimedia, ambient lighting, digital radio, wireless connectivity, wireless phone charging, wireless Apple CarPlay and Android Auto, automatic headlights, full LED lighting, and dual-zone climate control. That’s quite a bit of gear for the money.
But throw another four grand on the sales rep's desk, and you into the Ultra grade which adds heated, cooled and massaging front seats, eight-way power adjustment for the driver’s chair, Nappa leather inserts, underbody protection, a front differential lock and no less than 64 colour choices for the expanded ambient lighting package.
Fundamentally, then, your extra $4000 is buying the clever front seats and front diff lock, but that’s easily worth the money anyhow. That said, the entry-level variant is one of the better equipped at that price-point, so either way, you won’t be slumming it.
The KGM Musso is available in three grades - ELX, Advance, and the Ultimate. All three can be optioned up with an XLV Pack, which adds a 300mm longer tub giving you an additional 251L rear tub capacity, along with a 110mm longer wheelbase. XLV also increases maximum torque from 400Nm to 420Nm.
At the time of writing, our test vehicle, the Advance, has drive-away price of $48,700.
Standard features in the Advance include 12.3-inch touchscreen multimedia system (with wireless Apple CarPlay and Android Auto), 12.3-inch digital LCD instrument cluster, leather-accented heated and ventilated front seats with electric adjustment, 18-inch black alloy wheels, HID headlights, LED daytime running lights, and a suite of driver-assist tech, but more on that in the Safety section below.
Exterior paint choices include Grand White (no extra charge), Amazonian Green (metallic paint), Marble Grey (metallic paint), Pearl White (metallic paint) and Space Black (metallic paint). Metallic paint is available for $700.
The Tank’s plug-in driveline, starts with a petrol engine measuring 2.0-litres and contributing 180kW to the overall picture. But then there’s a single electric motor, sandwiched between the petrol engine and the nine-speed transmission. That means the Tank is still a mechanical four-wheel-drive platform, and when both powerplants are singing together, there’s an eye-opening 300kW and 750Nm of torque on tap.
The four-wheel-drive system operates as a rear-wheel drive on dry bitumen, and there’s the usual 4WD high range and 4WD low range. What there isn’t, is a 4WD-auto setting that allows you to use four-wheel drive in the dry on a paved road. That sounds minor, but for towing in particular, having all four wheels doing the driving is a major safety bonus.
All Tank 300s get a rear differential lock, but this version, the Ultra, also gets a locking front diff as well. Typically, the Tank also features a range of driving modes (no less than nine of them!) for the four-wheel-drive function, tailoring throttle, transmission and differential response according to the type of terrain being covered.
The Tank 300 is built the old fashioned way with a ladder-chassis upon which the body is bolted, and it still uses a live rear axle, too. But the front suspension is independent and the GWM uses coil springs rather than old-school leaf springs for much better ride quality.
The KGM Musso Advance with the XLV Pack has a 2.2-litre four-cylinder turbo-diesel engine – producing 133kW at 4000rpm and 420Nm from at 1600-2600rpm – it gets an extra 20Nm over the shorter version's 400Nm from 1400 to 2800rpm.
It has a six-speed automatic transmission, part-time 4x4 with high and low range, and an auto-locking rear differential.
This is a sluggish combination producing a generally lacklustre performance and the powertrain is not particularly efficient but, having said that, the Aisin auto is a reliable, well-proven transmission and the Musso ultimately does reasonably well with what it has.
The 4WD mechanicals and driver-assist tech actually work better in this package than they do in the Musso’s stablemate, the Rexton.
The headline number here is GWM’s official fuel consumption number of just 1.9 litres per 100km. Or it would be if it had anything to do with the real world. As it is, nobody is going to achieve that, and our mix of urban running netted an average of about 11.0 litres per 100km, with that dropping to 8.5 litres per 100km in country conditions.
The truth is, your consumption in this vehicle can go from zero to, say, 12 litres per 100km depending on how and where you drive and how much battery charge you have available.
Speaking of charging, the Tank 300 can use a commercial fast charger to absorb voltage at a rate of 50kW. At that rate, it can go from 30 to 80 per cent charged in about 24 minutes. A wall box (GWM offers one as a factory option) can take the 37.1kWh battery from 15 per cent to fully charged in 6.5 hours. And, of course, you can also charge the Tank from a domestic wall socket in a claimed 14.4 hours. We managed to add about 6km worth of charge per hour on such an outlet during our time with the car.
As far as range goes, GWM reckons there’s 115km (NEDC) of EV-only range, while starting a journey with a fully charged battery and a full 70-litre fuel tank should see you covering somewhere between 900 and 950km between top ups.
Official fuel consumption for the Musso Advance with the XLV treatment is 9.0L/100km.
On this test, I recorded 11L/100km, but on the test I spent a chunk of time in 4WD high and low range.
The Musso has a 75-litre fuel tank, so going by my on test fuel-consumption figures, from a full tank, you could reasonably expect a driving range of about 681km.
But it is worth noting that I didn't have a lot of weight on board during this test – it was just me and the vehicle recovery gear – and you will have a lot more weight on board: your family or your mates, pets, camping gear, surfboards, kayaks, the whole kit and caboodle.
GWM claims a 0-100km/h acceleration time of just 6.3 seconds for the Tank 300 PHEV, and that’s impressive. There are two caveats here. The first is that you need at least 40 per cent battery charge on board to extract maximum thrust. And, secondly, even in those circumstances, the Tank never feels that brisk. It’s more effortless than genuinely rapid, although the torque up hills is genuinely impressive.
There’s no getting around the refinement inherent in using volts for some of the time. And when the petrol engine does chime in, it’s all but imperceptible. You’ll eventually hear the engine if you wring it right out, but even then, vibrations are minimal.
All in all, the Tank’s relatively compact dimensions work in its favour in an urban setting, and the range of camera views (including an off-road one showing you the obstacles you’re about to encounter) make parking a lot easier than it might have been. Only a high degree of distortion in the birds-eye-view camera mode takes a bit of getting used to.
On the move the ride quality is quite exceptional, and those coil springs really do make a difference. Even the usual council speed bumps don’t bother the Tank and the short wheelbase pitching we’ve seen in some similar vehicles just never emerges. Well chosen damper rates help, too, and there has been some Australian input into the way the Tank handles. It shows.
Steering, too, feels light and natural, although the almost constant fidgeting at the helm by the lane-keeping assistance program is annoying. And switching it off is not only a multi-button job, it needs to be done every time you start the vehicle.
Far and away the biggest hurdle in living with the Tank, however, is a throttle calibration that is way off the mark. Pressing the accelerator pedal initially doesn’t seem to do much at all, and then suddenly, the power comes in and you discover you’ve input too much throttle as the Tank surges away down the road, threatening to actually spin its tyres if there’s any gravel about. But not until that initial hesitation has caused the driver behind you to wonder aloud (I can lip-read) if you’re ever going to move at all. This needs to be fixed as a running change.
The all-important off-road driving experience is pretty sharp and the Tank 300 is a genuine competitor in this discipline. It’s extremely stable and capable on unsealed roads and tracks and the front and rear diff locks make it a proper adventurer’s rig.
It’s relatively demure dimensions also mean that it fits down the tracks and trails that have been created by decades of vehicles of a similar size, unlike some of the bigger new off-roaders we’re seeing that simply don’t fit in to the terrain so neatly.
Ultimately, the Tank’s stock tyres will be the limiting factor, but there are plenty of alternatives out there for a bit more off-road bite.
On-road, the longer-wheelbase Musso is composed and comfortable with well-subdued NVH (noise, vibration and harshness) levels adding to an impressive overall sense of low-key refinement.
The engine and auto work reasonably well together, but as mentioned earlier this is a sluggish unit and it takes some urging to get it going. Pronounced lag from stand-still can be disconcerting, especially when you need plenty of zip to punch you into the traffic flow.
This ute’s suspension – double-wishbone, coil springs and stabiliser bar at the front, multi-link with coil springs at the rear – is firm, mostly controlled, but the Musso becomes jittery on irregular surfaces, such as lumpy back-roads bitumen and mildly corrugated dirt tracks.
One noteworthy annoyance: the Musso does not have adaptive cruise control.
Despite that, the Musso is actually quite reasonable for general driving duties.
As a 4WD, the Musso actually performs pretty well. It is a long wheelbase ute, so you have to drive it with consideration because you have to take into account its shallow off-road angles – approach, departure and ramp over – and it has quite a large overhang of tub behind the rear axle.
It has an auto locking rear diff, which is clunky in operation and I’d prefer a switchable diff-lock, which you could select whenever you want to, but otherwise it's effective in a workman-like kind of fashion.
Steering is not too shabby, it has a nice weight to it in all situations, whether you are on the bitumen or a dirt track. Turning circle on this long-wheelbase ute is 12.2m, but it feels nimble to steer around on the tracks.
The Musso has part-time four-wheel drive and high and low range 4WD gearing. It doesn't have a lot of power and torque in terms of the contemporary dual-cab ute market, but it does fine with what it does have; 420Nm in the XLV Musso gives it that little bit of extra punch over the standard Musso (400Nm) and that torque is available across a decent spread of revs.
If you intend to use your Musso as an off-road adventure vehicle or a weekend holiday machine, then it's handy to know that it's unbraked towing capacity is 750kg and its braked towing capacity is 3500kg and that's on par with the dual-cab ute market.
In terms of tyres, it’s the same story here as with most standard 4WDs – the Musso’s Nexen NPriz RH7 (255/60R18 108H) are not well-suited to anything other than light off-roading. The easy fix? Replace those tyres with some decent all-terrain tyres.
Payload is a listed 880kg (790kg in the standard Advance), GVM is 2980kg and GCM is 6480kg.
The Tank has a strong safety story to tell, especially on paper.
Regardless of what specification you buy, you’ll get seven airbags including full-length side-curtain bags and a centre airbag to reduce head injuries in a side-impact crash.
There are rear parking sensors, a range of camera angles including an overhead view, tyre-pressure monitoring, Isofix child-restraint mounts, and the usual driver aids including autonomous emergency braking, rear cross-traffic alert and braking, blind-spot monitoring, traffic-sign recognition and rear collision warning.
But away from the brochure, features such as the lane-keeping assistance and the driver-fatigue monitor need work on their calibration. GWM is by no means on its own here, but it’s a fact that some other makers do a better job of making this tech transparent and vastly less intrusive.
The original Tank 300 launched in Australia in 2022 scored five safety stars in ANCAP testing, and that rating has been carried over to this car.
The Musso does not have an ANCAP rating because it has not been officially tested.
As standard, the XLV Advance has six airbags, auto emergency braking (AEB), lane departure warning, trailer sway control, blind-spot monitoring, rear cross-traffic alert, front/rear parking sensors plus reversing cameras and more.
Adaptive cruise control is not offered on Mussos in Australia, only old school cruise control.
GWM offers a seven year/unlimited kilometre warranty on the Tank 300, as well as eight years of cover for the hybrid battery (also with no kilometre limit). There’s also seven years of roadside assistance thrown in, too.
Capped-price servicing is available for the first seven years, with the first service due at 12 months or 10,000km and subsequent services every 12 months of 15,000km after that. Prices for each service (in order) are: $320, $460, $460, $685, $685, $1075, and $370.
GWM has a network of 123 new-car dealerships able to handle servicing, and the company tells us that regional centres have not been forgotten.
The MY26 Musso range is covered by a seven-year/unlimited kilometre new-vehicle warranty, and five years of roadside assistance.
A service is required every 12 months or 15,000km, whichever occurs soonest with cost per service either $418 or $522.
Note, KGM considers off-roading as an example of a “severe driving condition” and so your Musso may require more frequent servicing.
KGM Australia has more than 50 dealerships across the country with a decent spread across metro and regional areas. Rextons can be serviced at those dealers or at approved workshops.
