Isuzu MU-X vs GWM Tank 300

What's the difference?

So, engine aside, not much new for the 2024 MU-X, but I can confidently say this: if you’re not towing big loads all of the time, then the 1.9-litre turbo-diesel won’t just save you cash at the dealership, but at the service station, too.

The GWM Tank 300 is an impressive 4WD wagon. Build quality, ride and handling and off-road capability all deserve praise.

So, is the petrol Tank 300 4WD worth spending your hard-earned cash on? After two off-road tests in it, and spending a bit of time in it on-road as well, I reckon, yes.

It’s packed with standard features, purpose-built for 4WDing and it’s well priced, especially when anything that can match it for features, comfort and capability costs about $20,000 more.

If you like the look of the 2023 Isuzu MU-X, then boy have I got good news for you, because the changes to the 2024 model occur under the bonnet, and nowhere else, really. That means you get the same simple, boxy exterior design, which emphasises capability over fanciness.

Yes, the MU-X design is more dependable than daring, but I reckon it works, with the three-row SUV cutting a fairly handsome figure, even if it is yet to receive the design tweaks just rolled out on the updated Isuzu D-Max.

Inside, though, it definitely presents as a little utilitarian, with some plastics that feel like they could survive a nuclear blast, and the 7.0- and 9.0-inch central screens both feel a little underwhelming by modern standards.

It all feels very comfortable and hard-wearing though, which is probably every bit as important, given the MU-X’s target market.

The Tank 300 looks like a mash-up of a Ford Bronco and a five-door Suzuki Jimny; it’s a boxy 4WD with prominent wheel arches and just as pronounced side steps.

Inside and out, it’s a striking blend of old and new, cool retro style with a modern touch. 

Our test vehicle was an eye-catching Dusk Orange colour. You’ll like it or loathe it.

Inside, there is a lot of hard plastic everywhere, more than merely a nod to its engineered purpose as a rugged 4WD adventure machine, and that ties in with its all-around ready-for-real-life character.

But leather and soft-touch surfaces throughout provide a low-key sense of classy balance to those durable plasticky aspects.

The 12.3-inch touchscreen is clear and bright and the centre console is a mix of traditional and on-screen buttons – but more about the multi-media system below.

Worth noting is the fact that while the directional air vents look fine they feel rather flimsy once you start moving them around to open/close/direct them.

Practicality has always been a sizeable MU-X perk, regardless of the engine. 

That starts with seven seats, and a back row where actual full-size humans can spend time — and there are not many three-row SUVs you can say that about.

I’m 175cm tall and while I wouldn’t pick row three as my first choice, I’d happily sit back there for short hops.

The middle row, too, is pretty spacious, though it is lacking in a few creature comforts, with just the air-con vents (but no temp controls) and a couple of USB ports to keep you company.

And remember when I said the brand was promising the 1.9-litre engine wouldn’t cost much in terms of capability? Well, Isuzu says the braked towing capacity for models fitted with the smaller engine is 3000kg, while the payload figure increases — now up to 735kg — mostly because the new engine is about 70 kilos lighter. Models fitted with the 3.0-litre turbo-diesel are still rated to tow 3.5-tonne. 

The MU-X stretches 4850mm in length, 1870mm in width and 1815mm in height and it sits on a 2855mm wheelbase, which means while there’s plenty of cabin space it’s not too ridiculous to park.

You’ll find 311 litres of boot space with all three rows in place, growing to 1119 litres with the second row folded flat and 2138 litres with just the front two seats in action.

Every MU-X model will offer at least 800mm in wading depth and 230mm ground clearance, too.

The interior is either 'Comfort-Tek' synthetic leather seating (Lux), or Nappa leather seating (Ultra) and beyond those soft-touch surfaces the Tank 300 has a practical and comfortable interior.

The Ultra has five seats, bucket-style up front for the driver and front passenger (both okay, but not ideal in terms of support and comfort), and a three-seat bench-style second row in a 60/40 split configuration. 

In the grand tradition of second-row seats it's okay, not great. The second row folds flat to expand the rear cargo space.

Cargo space is a listed 400 litres when the second row seats are in use, and 1635 litres when that second row is stowed away.

The 12.3-inch touchscreen multimedia system is easy enough to use even if the English-as-a-second-language wording on some of the driving-mode explanations is off-target every now and again.

The audio system is nine-speaker in the Lux and Ultra, but the Ultra's is described as 'Premium'.

There's wireless charging, front and rear USB ports, as well as 12V and 220V power outlets.

The seats are Nappa leather accented, heated and cooled (up front), and the driver gets an eight-way power-adjustable perch (with lumbar adjustment and massage function). 

The 64-colour ambient lighting is a discotheque touch at night.

The Tank 300 petrol line-up has two variants: the Lux ($46,990 drive-away) and Ultra ($50,990 drive-away).

Standard features include a 12.3-inch touchscreen multimedia system (with Apple CarPlay and Android Auto), wireless charging, 12V and 220V power outlets, Nappa leather accented seats, heated and cooled (front) seats, eight-way power-adjustable driver’s seat with lumbar adjustment and massage, nine-speaker premium audio, auto-dimming rear-view mirror, front and rear diff locks, 18-inch alloy wheels, 64-colour ambient lighting and more.

It has LED headlights and tail-lights, front and rear USB ports, a sunroof, side steps, roof rails, seven airbags (including front centre), and a stack of driver-assist tech including AEB and forward collision warning, lane departure warning, lane keep assist, lane centre keep, emergency lane keep, adaptive cruise control, traffic sign recognition, rear cross traffic alert with brake, tyre pressure monitoring, front parking sensors and rear parking sensors, 360-degree around-view camera, transparent chassis function and more.

The GWM Tank 300 is available with five different paint jobs: 'Fossil Grey' is no-extra-cost standard, but 'Lunar Red', 'Pearl White', 'Crystal Black' or 'Dusk Orange' each cost $595, at time of writing.

Let’s focus on the new engine option here, with the 1.9-litre turbo-diesel delivering 110kW and 350Nm. They don’t sound like massive numbers, but Isuzu makes the point that the torque delivery is wide, with maximum grunt available from 1800rpm to 2600rpm, and 300Nm available from 1550rpm to 3700rpm, meaning there’s power there when you need it.

The new engine pairs with a six-speed Aisin tramsission and delivers power to two or all four wheels.

The Tank 300 petrol has a 2.0-litre turbo-petrol four-cylinder engine, producing 162kW at 5500rpm and 380Nm from 1800 to 3600rpm.

It has an eight-speed torque-converter automatic transmission (the hybrid has a nine-speed auto) and a part-time four-wheel drive system with 4WD high-range and 4WD low-range for off-roading.

Another perk of the smaller engine is a smaller fuel bill, with the 1.9-litre turbo-diesel promising to drink 7.4L/100km on the combined cycle - almost a litre less than the 3.0-litre 4x4 model, which is more like 8.3L/100km. 

Emissions drop, too, with the smaller engine rated at 196g/km of C02 combined, compared with 220g/km on for the 3.0-litre 4x4 model.

Impact on the hip pocket? Well, fewer trips to the service station for one. Isuzu says the 80-litre fuel tank should deliver almost 1100km of driving between refills.

The GWM Tank 300 Ultra petrol has a listed combined cycle fuel consumption figure of 9.5L/100km. It uses regular unleaded fuel.

On test I recorded 10.4L/100km from pump to pump.

The Tank 300 has a 75-litre fuel tank so, going by the fuel figures above, you could reasonably expect a driving range of about 720km from a full tank. 

Note: Drop 30-50km off any driving-range figure for a better idea of your vehicle’s safe touring range. Also, remember that numerous other factors affect your fuel consumption and so impact your touring range, including how much extra weight you have onboard (passengers, camping gear etc), whether your vehicle is fitted with any aftermarket equipment (bullbar, spare-wheel carrier, etc), whether you are towing (a camper-trailer, caravan, or boat etc), your vehicle's tyre pressures and the conditions.

First things first, you can absolutely tow with the smaller MU-X engine. In fact, we attached a load weighing close to its 3.0-tonne maximum and the Isuzu just hunkered down and got to work.

It must be said, though, it’s nowhere near as effortless as when you have the bigger 3.0-litre turbo-diesel engine up front, which dispatches heavy loads clinically and easily.

The smaller option has to try harder and rev higher, and while it’s easy enough on downhill runs or flats, it’s noticeably slower when heading up hill.

It does demand the question of how often you’ll be attaching close to its rated maximum on the towball, though. If it’s often, the bigger engine is definitely for you. But if it’s occasionally, or your tow loads are lighter, you can definitely make do with the 1.9-litre option.

On the road, the 1.9-litre engine’s power delivery is actually pretty well suited to the MU-X. It’s not fast, of course, but the width of the torque band helps deliver grunt when you need it (to a point) especially in the low-end, and I reckon the whole experience is a bit smoother and quieter than with the bigger engine, too.

You are missing some of that effortless grunt, of course, and you still can’t escape the usual diesel noise that permeates the cabin, but the lower fuel use for lower power feels like a fairly decent trade. 

It won’t be for everyone, and cross-country travellers and towers will no doubt go for the bigger unit, but for everyone else the 1.9-litre is a pretty sensible option.

I covered about 400km in total, on sealed surfaces in between off-road testing and overall the Tank 300 was rather impressive.

It’s quiet and refined on-road but has few alarming characteristics, which I’ll get to soon.

The petrol engine is lively and punches this 2106kg wagon along at a nice clip.

Steering has a sporty weight to it and is precise enough for easy driving in the city, suburbs and on the highway.

Ride and handling is nicely composed – mostly. It feels a bit floaty at times, some body-roll creeps in during livelier turns and there is a spongy feel to the coil-spring suspension.

But, other than that, this 4WD consistently feels stable and planted.

NVH (noise, vibration and harshness) levels are kept to a minimum, though there’s some wind rush around the chunky wing mirrors.

Visibility is reasonable but a bit pinched in places. The big bonnet can impact the driver’s forward vision, and that’s why, when you’re 4WDing, the Tank 300’s transparent chassis function comes in handy.

As for those 'alarming characteristics' I mentioned earlier…

Under heavy braking the Tank 300 pitches forward severely, with seemingly all momentum forcing the vehicle into a disconcerting nose-dive. Not good.

Driver-assist tech is generally seamless, but lane keep assist is too harsh and too pre-emptive in its application – wrenching you into line whenever it ‘thinks' you have drifted too far off-centre.

Auto stop-start engages abruptly and there is a disconcerting amount of lag before the vehicle starts again from standstill.

Not good at all when you need quick off-the-mark pace to safely merge with traffic from a stop light or after a lengthy pause at a roundabout.

The Tank 300 did however prove to be an effective off-roader. It handled the gravel track to our 4WD test site with ease.

This route is peppered with light corrugations, as well as, deeper into the bush, severe ruts and potholes, so it’s not an easy drive for any standard 4WD.

But this GWM wagon in 4WD high-range, did well, and was only ever rattled (a bit) when we hit a section of much deeper wheel ruts and potholes where modified 4WDs had damaged the track. 

My patented ‘Watch out for that 'roo!' emergency-braking test again revealed the Tank 300’s tendency to pitch forward dramatically under heavy braking and it took some work to keep the vehicle on track. 

The Tank 300 is well suited to low-range 4WDing. It may not have a ton of torque on tap (380Nm), but that pulling power is available across a decent rev range and this 4WD makes efficient use of what it does have.

Its off-road driving modes, including 'Mud/Sand', 'Rock', 'Mountain' and 'Pothole', seem calibrated appropriately for the demands of different terrain, although I wouldn’t rely on them, too much.

In the middle of an Aussie summer I didn’t get to test the ‘Snow’ setting, but when you engage some of the modes it will lock diffs where appropriate.

Low-range gearing is sound, without being Jeep Wrangler Rubicon great, and with its front and rear diffs locked, the Tank 300 tackled every 4WD challenge with ease.

Visibility is restricted in places due to the cabin build style, but that’s not such an issue when you’re 4WDing at very low speeds – you can always stop and get out of the vehicle to check the track ahead.

However, the Tank 300’s 'Transparent Chassis' function goes some of the way to improving driver visibility.

This system is similar to the 'Transparent Bonnet' view in the Land Rover Defender in that its aim is to extend the range of the around-view camera to include a view under the Tank 300 (represented on-screen as a ‘ghost vehicle’ outline when Transparent Chassis is selected).

Wheel travel is decent enough – the Tank 300 has a live rear axle – but the standard Michelin Primacy SUV tyres (265/60 R18) are not well suited to 4WDing. Fit a decent set of aggressive all-terrains to make this 4WD wagon even better off-road.

The Tank 300 loses a few off-road efficacy points, though, because…

It feels low. Ground clearance is listed as 224mm, and it has official approach and departure angles of 33 and 34 degrees, respectively (no ramp-over angle is listed), but it feels vulnerable to scraping its undercarriage on the earth.

Its pronounced side steps also seem to nudge the ground when you’re traversing rough terrain. Not among the Tank 300’s best features.

Listed payload is 446kg, which will quickly be used up once you add aftermarket equipment, passengers, camping gear and your dogs to the mix.

Unbraked towing capacity is listed as 750kg, while braked capacity is 2500kg. 

The Tank 300 has the maximum five-star ANCAP safety rating from testing in 2022.

As standard, it has seven airbags and a comprehensive suite of driver-assist tech including AEB, forward collision warning, lane departure warning, lane keep assist, lane centre keep, emergency lane keep, adaptive cruise control (it worked for me on this test), traffic sign recognition, rear cross traffic alert with brake, tyre pressure monitoring, front and rear parking sensors and a 360-degree around-view camera.

Every Isuzu MU-X model gets a six-year, 150,000km warranty, as well as five years of capped price servicing, and up two seven years of roadside assistant. 

The service are 12 months or 15,000km, and each service costs $449 per year, or a total $2245 over five years.

The Tank 300 has a seven-year/unlimited kilometre factory warranty, five years of roadside assistance and five-year capped price servicing. 

Servicing intervals are set for every 12 months or 10,000km. 

Capped price servicing puts the costs at $300 each for the first, second and fifth service, and $550 each for the third and fourth service. That's an annual average of $400.
