What's the difference?
GWM’s Tank 300 struck a chord with Australian buyers when it launched in 2023. The rugged, boxy design, serious off-roading ability and unbeatable value for money - especially compared with similar models like the Jeep Wrangler - won it a number of new fans.
But something was missing. With an uninspiring petrol engine and a patchy hybrid powertrain the only options, the Tank 300 was sorely missing a diesel.
GWM itself says about 75 per cent of models in the off-road-focused large and upper-large SUV segments are made up of diesel-powered SUVs, so it was missing out on a chunk of sales.
Thanks to some serious nudging from GWM Australia and New Zealand, the Chinese parent company saw the potential and have added a diesel engine to the mix. This is the same diesel unit found in the GWM Cannon and Cannon Alpha utes.
Is the diesel now the pick of the Tank 300 range? Or should you look at another oil-burning 4x4?
A low purchase price will always be the most important factor for a solid core of bargain-hunting ute buyers, which no doubt includes some hard-working tradies. And if that brings a generous amount of standard equipment, then that vehicle will be even more appealing.
The GWM Cannon ute has clearly offered both since its local release in 2020, but its low pricing also came with inferior tow ratings and compromises in powertrain, ride/handling and refinement.
However, in 2025 GWM has released an upgraded version designed with Australian customer-led feedback in mind, featuring a larger engine and towing capacity plus enhanced technology, styling and, yes, refinement.
We recently spent a week in one of the new models to assess its performance and practicality from a tradie’s perspective.
The diesel is now the pick of the Tank 300 range. It’s the best fit for this vehicle and offers greater driver engagement than the petrol or hybrid.
It also has genuine off-road chops while still managing to suit family life.
While it could benefit from further refinements to on-road behaviour, cabin noise and the ADAS systems, none of these are deal breakers.
The fact that it is priced so keenly against some excellent competitors and is stacked with standard gear adds to the Tank 300’s appeal.
Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.
The latest version of the Cannon ute displays commendable improvement in key areas like drivetrain and chassis tuning, along with a benchmark 3500kg tow rating, heaps of standard equipment and a generous warranty for a list price well under $50K. For a tradie on a budget, it represents value that's hard to ignore.
The only visible difference between the diesel and the petrol or hybrid 300s is a 2.4T badge. So you get the same boxy exterior as before.
It’s somewhat derivative and gives more than a nod to Jeep, but the design has intent - it looks capable off-road and for most people that’s enough. Luckily it is capable off-road. More on that later.
Inside the upright, shelf-like dash is appealing. I like that everything is nicely integrated, like the dual 12.3-inch screens which flow nicely into one another.
The big T-shaped three-spoke steering wheel looks cool and the aeronautical air vents are clearly inspired by Mercedes-Benz.
The chunky metal-look plastic glove box cover adds extra visual flair and the stitching throughout elevates the cabin further.
However, the futuristic looking gear shifter is chunky, takes up too much space and is unnecessary.
The upgraded Cannon brings refreshed exterior styling, with the front fascia featuring a new grille and bumper design, larger fog lights and more subtle use of chrome highlights.
At the rear there’s more prominent (and permanent) brand identification with bold ‘GWM’ lettering embossed on the tailgate panel, which is a welcome blast from our pick-up past.
The spacious interior design has also been enhanced with use of what GWM calls ‘premium materials’ including soft-touch surfaces on the dash and door panels along with subtle chrome accents.
There’s also a new steering wheel and the centre console has been redesigned with less buttons and dials (not always a good thing) topped by the new multimedia touchscreen.
Up front the Tank 300 offers a commanding view of the road and it’s easy to find your perfect driving position thanks to the power-adjustable seats.
Those seats have good side bolstering but could do with a little extra cushioning for the thighs. The Nappa leather-appointed seats in the Ultra look and feel lovely.
Storage is average for the segment with room for larger bottles and additional flat items in the door pockets, and a well-sized central bin that also houses two cupholders, although they sit low in the cavity and two coffees sit awkwardly together.
The Tank has one USB-C port for charging only but another USB-A port up front for connectivity. You shouldn’t need that given Apple CarPlay and Android Auto is wireless.
Keen off-roaders will have fun with the extensive Tank Expert Mode in the multimedia screen, which allows you to individualise your 4WD experience.
Beyond that the screen is neatly laid out, responsive and easy to use. GWM has come a long way when it comes to in-car tech. The icons on the digital instrument cluster, however, are still too small.
There’s ample leg room in the rear, with space between my knees (I am 184cm tall) and the rear of the front seat, and enough toe room. It doesn’t feel enormously spacious across the rear row but three kids should be comfy. Headroom is enhanced by a scalloped section of the roof specifically for rear-seat passengers, but it doesn’t leave a huge amount of space for taller people.
The rear seat bench is flat but the backrests have some support and overall the seats back there are comfortable.
You’ll find lower rear-seat air vents, map pockets, a fold-down central arm rest with two cupholders, room for small bottles in the doors and two USB-A ports.
The boot can take 400 litres with all seats up and 1635L with the rear seats folded. That figure is measured from the floor to the top of the rear seats.
Jeep says the Wrangler has 898L capacity with all seats in place but that is measured from the floor to the roofline.
There is no under-floor storage in the 300’s boot and the full-size spare wheel is housed in traditional 4x4 fashion on the tailgate.
With its 2230kg kerb weight and 3225kg GVM, the Cannon Ultra has a 995kg payload rating (that’s close enough to a ‘one-tonner’ by our measure) and the latest upgrades include an increase in braked tow rating from the previous 3000kg to the class-benchmark 3500kg.
However, with its 6200kg GCM (or how much it can legally carry and tow at the same time) our test vehicle would require a substantial payload reduction of more than half a tonne (525kg) to tow its maximum trailer weight (but it’s not alone there).
And that would leave 470kg of payload capacity, most of which could be used up by the weight of a hefty five-member working crew before you could think about loading any of their tools and other equipment.
Fact is, few (if any) owners would need to tow 3500kg, but it’s important to be aware of these numbers if you do plan to tow that heavy and want to stay on the right side of the law.
The square load tub is 1520mm long and wide and 540mm deep, but with 1146mm between the rear wheel-housings it won’t fit a standard Aussie pallet. However, it will accommodate Euro pallets, if hauling such payloads is important.
The tub’s internal surfaces are protected by a spray-in liner and there are load-anchorage points front and back, with the rears close to floor level (ideal for all loads) and the fronts near the tops of the sidewalls (not ideal for low loads). The tailgate is equipped with hydraulic dampers to assist opening/closing and the handy fold-out step allows easy entry to the load tub.
Cabin storage includes a bottle holder and bin in each front door, a small lower dash compartment on the driver’s right and a slender bin above the glove box on the passenger side.
The centre console has a wireless phone-charging pad, 12V socket and two USB ports up front, plus cup/small-bottle holders and a lidded box at the back with an internal air conditioning cooling vent and sliding upper storage tray.
The rear seat has adequate legroom even for tall people, given I’m 186cm and have about 60mm of knee clearance when seated behind the driver’s seat in my position.
Headroom is adequate though not as generous and the deep contour in the roof lining to allow for the sunroof can make tall rear passengers feel a bit closed-in.
Shoulder room can also be squeezy for three large Aussies, so like all dual cab utes short of a full-size US pick-up it’s okay for short trips but ideal for two on longer drives.
There’s a bin and bottle-holder in each rear door and pockets on both front seat backrests. The 60/40-split seat bases can also fold up and by stored vertically for more internal load space, or to access wheel-changing equipment.
One of the key selling points across GWM’s entire range is value for money, and the Tank 300 has always had that in spades.
As with the petrol and hybrid 300, the diesel is offered in two well-specified model grades - Lux and Ultra.
At $47,990 drive-away, the Lux diesel is $2000 more than the Lux petrol, but $3000 cheaper than the Lux hybrid.
The Ultra diesel, at $51,990, is $1000 pricier than the petrol equivalent and $5000 more affordable than the hybrid Ultra.
The GWM Tank 300 diesel Lux is also more affordable than equivalent grades of a number of ladder-frame 4x4 SUV rivals like the Isuzu MU-X, Toyota Fortuner, SsangYong Rexton and the Ford Everest.
It’s also significantly more affordable than the Jeep Wrangler, with the Tank 300 Lux costing about $30,000 less than a Wrangler Unlimited Sport S.
Note however that many of those models - except the Wrangler - have the option of seven seats, whereas the Tank is strictly a five-seat proposition. If you want a third row, check out GWM’s Tank 500.
There are cheaper off-road large SUVs out there – the LDV D90 and Mahindra Scorpio. But the Tank 300 is a more refined and higher-quality offering than those models.
Standard gear in the Lux includes 17-inch alloy wheels, synthetic leather seats and steering wheel, power-adjustable front seats, dual-zone climate control, seven-colour ambient lighting, keyless entry and start, a sunroof, power-folding mirrors, paddle-shifters, a nine-speaker audio system with digital radio, built-in sat-nav, and a pair of 12.3 inch digital displays with wireless Apple CarPlay and Android Auto.
It also gets roof rails, side steps, privacy glass, all-terrain mode selection and a rear diff lock.
The Ultra upgrades to 18-inch wheels, Nappa leather-accented seats, heated and ventilated front seats, a heated steering wheel, more adjustment for the front seats and a memory setting, a massage function for the driver’s seat, a wireless phone charger, 64 colours in the ambient lighting suite, and a nine-speaker premium audio system.
There is nothing obvious missing from the standard features list, but I don’t know why a wireless device charger is limited to the top grade.
Our test vehicle is the Ultra model grade, which sits above the entry-level Lux and below the Vanta and top-shelf XSR in the four-model Cannon range.
Like its siblings, the Ultra comes standard with a bigger 2.4-litre four-cylinder turbo-diesel engine sourced from its larger Alpha stablemate and new nine-speed automatic for $41,990 plus on-road costs ($43,490 drive-away).
Even with its optional 'Pittsburgh Silver' premium paint, which adds $595, that pricing represents compelling value given you need at least $50K just to get into a relatively spartan base-model Ford Ranger XL or Toyota HiLux Workmate 4x4 dual cab ute equivalent.
The Ultra has heaps of standard equipment, given that the entry-level Lux on which it’s based includes 18-inch two-tone chrome alloy wheels with 265/60R18 tyres and a full-size steel spare, chrome sports bar, LED lighting including DRLs, side-steps, roof rails, spray-in tub-liner, rear parking sensors, reversing camera, tyre pressure monitoring, driver’s 7.0-inch digital instrument cluster and six-speaker audio with a 12.3-inch multimedia touchscreen offering digital radio, Apple CarPlay/Android Auto connectivity and more.
To this list the Ultra adds an electric sunroof, tailgate step and rear privacy glass, plus leather-accented seats with power-adjustable front buckets equipped with heating and cooling.
The steering wheel is also heated plus there’s a USB port for a dashcam, ambient lighting, auto-dimming rear view mirror, 360-degree camera view and front parking sensors.
The big news with the Tank 300 is, of course, the new engine.
It is a 2.4-litre four-cylinder turbocharged diesel engine borrowed from the GWM Cannon and Cannon Alpha utes.
It pumps out 135kW of power and 480Nm of torque. That’s more torque than an MU-X but not as much as an Everest.
It is paired with a nine-speed automatic transmission and has part-time four-wheel drive.
If you need to tow, the diesel has a 3000kg towing capacity, which is 500kg more than the hybrid and petrol. It can’t beat the 3.5-tonne towing capacity of the MU-X and the Everest.
Payload has also increased compared with the petrol and hybrid, up from 400kg to 600kg.
GWM says it conducted extensive testing internationally but also in Australia to improve towing performance. There are approximately 20 different parts compared with the other powertrain variants to get the best out of towing in the diesel.
A rear diff lock is standard on both grades while the Ultra gains a front diff lock.
The Cannon's engine capacity has increased 20 per cent by adopting the Alpha's 2.4-litre four-cylinder turbo-diesel. It produces 135kW of power at 3600rpm and 480Nm of torque between 1500-2500rpm, which represents a 12.5 per cent power increase and 20 per cent more torque.
This is paired with GWM’s new homegrown nine-speed torque converter automatic (previously eight-speed) which has overdrive on the top three ratios and there are steering wheel paddle-shifters for sequential manual-shifting.
The 4x4 system is a ‘torque on demand’ design that transmits power to the rear axle under normal driving conditions to optimise fuel economy, but automatically sends power to the front axle if a loss of rear axle traction is detected.
It also offers a choice of selectable drive modes comprising 'Normal' (default), 'Sport' and 'Eco', plus 4H (4x4 High Range) and 4L (4x4 Low Range). The latter is only for the rough stuff, where the selectable electronic rear diff-lock could also come in handy.
The diesel Tank 300 consumes 7.8 litres of fuel per 100 kilometres on the official combined cycle, which is better than the 9.5L figure for the petrol and the 8.4L quoted for the hybrid.
That figure also sits somewhere between a 2.0-litre bi-turbo Everest (7.1L/100km) and a 3.0L MU-X (8.3L/100km).
It has a 75-litre fuel tank and GWM claims an NEDC range of about 950 kilometres. GWM says the Euro 5 engine does not require Adblue.
Given the restrictions of a media launch, we did not obtain real-world fuel use figures.
GWM claims official combined consumption of 8.4L/100km and the dash display was showing 9.6 at the completion of our 321km test, which comprised the usual mix of suburban, city and highway driving, of which about one third of that distance was hauling its maximum payload. The engine auto start/stop function was switched off for the duration.
Our own figure of 9.7L/100km, crunched from actual fuel bowser and tripmeter readings, was line-ball with the Cannon’s onboard calculation, which proved its accuracy. It also validated our test vehicle’s real-world sub-10L/100km consumption, which is excellent for a two-tonne-plus ute and gets a big thumbs-up from us.
Therefore, based on our test figure, you could expect a real-world driving range of around 800km from its 78-litre diesel tank.
I last drove a Tank 300 in late 2023 and it was the hybrid variant. While the hybrid has some positives, its driving characteristics were not high on that list.
It had an erratic throttle response, hesitation on take-off and it felt underdone.
In contrast, this new diesel variant just feels like the right fit for this SUV.
There is slight lag accelerating from a standing start, but the powertrain is torquey and there’s plenty on tap when overtaking or just increasing speed when already on the go. GWM has not provided a 0-100km/h time.
It is clear you’re in a diesel as soon as you turn on the ignition - it has that typical diesel rattle, but it is not as unsophisticated as some oil-burners I have driven.
The cabin could do with some extra insulation with wind and tyre noise detected, but it’s hardly a deal breaker.
Given the vehicle’s size, heft (nearly 2.3-tonne kerb weight) and the fact it’s shaped like a brick, the 300 holds its nerve on winding stretches of road with only a little body roll. In saying that, best not to treat it like a Mini Cooper on your favourite twisty road.
Ride quality is a bit mixed. We only drove the Ultra on 18-inch wheels and while it manages to soak up bumps, the ride is jittery, and that’s even more evident on uneven road surfaces.
Steering is heavily weighted and a little vague, but fine for a big off-roader, and the brakes need to be pushed hard.
One quirk is the indicator - it appears to be a one-touch setup for indicating to change lanes, but then the indicator stays on. I tried several times to test this, even flicking it to the opposite side to turn it off and it was very stubborn.
The good news is it appears GWM has toned down the awful indicator sound of its earlier models and is now much more subtle.
So on-road the Tank 300 is more than competent, and a much nicer vehicle to drive in an urban setting than a Jeep Wrangler, for example.
We also drove it briefly on an off-road trail, and in low range the Tank 300 proved that it can do what it says on the box.
I’m no off-roading expert and there are much more challenging trails out there, but I had confidence that the Tank 300 would not let me down traversing the many chunky rocks, massive holes and fallen tree limbs.
Even though there’s no adjustment for base-cushion rake or lumber support on the driver’s seat, we didn’t suffer any discomfort during our test. There are also three steering wheel assist modes to choose from comprising 'Light', 'Comfort' (default) and 'Sport'.
The new 2.4-litre engine effectively fills the gap that existed with the previous 2.0-litre, which felt underdone given this vehicle's size and weight. The big 20 per cent increase in torque is a noticeable improvement, as it pulls strongly from low rpm with gearing that keeps it within its peak zone most of the time.
It’s also relatively smooth and quiet and the three drive modes optimise performance in each setting. The Sport mode provides a noticeable increase in response, which in combination with the same setting for the steering is the most engaging drive experience.
The refined nine-speed auto is a sweet-shifting transmission in either auto or manual mode.
We were also pleasantly surprised by a big improvement in ride and handling, as this latest version of the Cannon feels like it finally has the beefier spring rates and damper settings this ute has been crying out for.
It’s also an effortless highway cruiser, with the overdriven top gear ensuring the engine requires less than 1800rpm to maintain 110km/h. However, although wind and engine noise is pleasantly low at these speeds, we did notice tyre noise emanating from the rear tyres into the cabin.
To test its GVM rating, we maxed out the payload to 990kg. This compressed the rear leaf-springs about 60mm, leaving around 40mm of static bump-stop clearance which ensured no bottoming-out on our test route.
It felt stable and sure-footed and the new drivetrain made light work of our 13 per cent gradient, 2.0km-long set climb at 60km/h, displaying ample pulling power in fourth gear to easily haul this load to the summit.
Engine-braking on the way down, in a manually-selected second gear, was arguably the best we’ve experienced in a sub-3.0-litre turbo-diesel with almost a tonne on its back.
Our only gripe is the emergency lane-keeping assist function, which needs more refinement as it creates weird fluctuations in steering weight and aggressively tugs at the wheel when you get anywhere near a white line.
Fortunately, this can be disabled in the vehicle settings menu, but unfortunately must be switched off before each drive.
ANCAP awarded the Tank 300 a five-star crash safety rating from testing done in 2022, scoring highly across all four of the major test categories.
GWM says it is waiting to hear from ANCAP but expects the diesel to be covered by the same rating.
As well as seven airbags including a front centre bag, the Tank 300 has a long list of safety gear covering both the Lux and Ultra.
There’s a suite of collision mitigation systems that includes auto emergency braking (AEB), lane departure warning, lane-keep assist, emergency lane keep, lane centring, front and rear collision warning, front and rear cross-traffic alert and lane change assist.
It also has driver fatigue monitoring, a rear seat child monitor, door opening warning, adaptive cruise, traffic sign recognition and hill-descent control.
I noted this in my recent GWM Haval H6 GT PHEV review, but GWM has made consistent tweaks to improve its advanced driver-assist systems (ADAS) and as a result they are less intrusive than they were when the Tank 300 launched in 2023.
There is still the occasional tugging of the wheel but it’s much less of a tug-of-war than it once was.
For the first 45 minutes of our test drive there was an annoying beep every 10 seconds that my co-driver and I could not identify. There was no icon on the driver display to indicate that it was a lane departure warning or speed limit alert, but eventually it just stopped. We still have no idea what it was but it was, thankfully, not present in the vehicle we drove in the second half of the launch drive.
The Cannon has a five-star ANCAP rating awarded in 2021 (expires 2027) and comes with seven airbags (including full-length side-curtain and centre-front), AEB including junction assist, front collision warning (pedestrian and cyclist), rear collision warning, rear cross-traffic alert with brake, blind-spot monitoring, lane-keeping, traffic sign recognition, trailer sway control, adaptive cruise control and lots more.
Junior tradies get ISOFIX child-restraint anchorages and top-tethers on the two outer rear seating positions.
GWM covers the Tank 300 with its seven-year/unlimited-kilometre new-vehicle warranty, which is an impressive offer.
You are covered for seven years of roadside assist and the Tank is offered with a seven-year capped-price servicing program.
GWM is yet to confirm the Tank 300 diesel’s servicing offer (including pricing), but expect a service schedule similar to the Cannon ute with the same powertrain.
That means the first service might be required at 5000km or six months and beyond that it will need a service every 12 months or 10,000km, whichever occurs first.
Like all GWM Cannons, our test vehicle comes with a generous seven-year/unlimited km warranty, which includes five years of roadside assist. Apart from the first service at 12 months or 10,000km, scheduled servicing is every 12 months/15,000km, whichever occurs first.
GWM offers capped-pricing for the first five scheduled services (60 months or 70,000km), which totals $2530, or an average of $506 per service.
