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?
The Mercedes-Benz Sprinter has long been a formidable competitor in the Light Duty (3501-8000kg GVM) division of Australia’s highly competitive Heavy Commercial vehicle market.
The popular range offers a choice of panel van, cab-chassis and minibus body styles, four turbo-diesel engine variants (plus an all-electric drivetrain), three wheelbase lengths and for panel vans plus the choice of two roof heights.
An extensive overhaul of the Sprinter range in 2024 brought extra safety technologies, new comfort and convenience features and other benefits, which Mercedes-Benz claims can help drivers work more efficiently. We recently put one of the latest models to the test.
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.
Given the original Sprinter was released in 1995, it’s not surprising the current third-generation model feels like it’s benefitted greatly from decades of continuous refinement. Although the list price difference between our test vehicle and its closest Chinese rival is substantial, the 417 MWB Panel Van is hard to fault in terms of driver comfort, safety and all-round competence. It really is very good.
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 417 MWB Panel Van rides on a 3665mm wheelbase (the shortest of three Sprinter wheelbases) and is almost 6.0 metres long (5932mm), more than 2.0 metres wide (2020mm) and stands almost 2.4 metres tall (2378mm). Its 12.4 metres kerb-to-kerb turning circle is impressively tight for a vehicle of this length.
It rides on simple and rugged MacPherson strut front suspension, with a robust live axle/leaf-spring arrangement under the tail. Steering is via rack and pinion and it has disc brakes all around.
Look beyond the optional silver metallic paint on our example and there’s extensive use of unpainted dark grey plastic on all the external surfaces where hard-working vans are most prone to wear and tear, including the hubcaps, front/rear bumpers, grille, door-handles/mirror shells and along the sides.
Its work-focused exterior styling is nicely integrated, combined with an equally neat and functional interior design that offers a visually-pleasing combination of patterned fabric seat-facings and hard surfaces that blend different shades of grey with splashes of satin chrome and piano black.
We also like the feel and response of mechanical switches (rather than touchscreen prompts) for adjusting settings like cabin temperature, fan speed and media volume.
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.
With its 2215kg kerb weight and 4100kg GVM, our test vehicle has a sizeable 1885kg payload rating.
It’s also rated to tow up to 2000kg of braked trailer and with its 6100kg GCM (or how it can legally carry and tow at the same time), that means it can tow its maximum trailer weight while hauling its maximum payload to ensure optimum versatility.
The cargo bay, which offers a cave-like 9.0 cubic metres of load volume and internal lighting front and rear, has internal dimensions of 3316mm length (with bulkhead), 1732mm width and 1719mm height.
So, with 1350mm between the rear wheel-housings, it can comfortably fit two standard 1165mm-square Aussie pallets or up to four 1200 x 800mm Euro pallets, held in place by a choice of 10 floor-mounted load-anchorage points.
The cargo bay is accessed through a single kerbside sliding door with a wide 1260mm opening, or symmetrical rear barn-doors with large handles on each pillar to assist operator access.
The barn-doors also have internal storage bins and open to a full 180-degrees to assist forklift and loading dock access. Thoughtfully, their hinge design also holds the doors firmly open at 180 degrees, to minimise the chance of wind gusts slamming them shut with potential injury to the operator.
There’s also plenty of cabin storage starting with two tiers of bins in each door, with the highest being spacious enough to hold large bottles.
There's also a deep shelf on the passenger side lower dash, a large lidded compartment in the central dash-pad and overhead shelves with lockable storage on the passenger side. Plus, the dash offers a total of eight cup/small-bottle holders.
The base cushion of the two-passenger bench seat is also hinged at the front, which allows it to tilt forward and provide access to a large hidden storage area beneath.
A crew of three can travel in relative comfort (for a commercial van that is) thanks to a central seating position that provides a sturdy hoop-handle for support, sufficient knee clearance from the dash even for tall people, and a reasonably flat and spacious floor area.
The cabin also features the latest next-gen 'MBUX' multimedia system with 10.25-inch touchscreen, which for the first time offers wireless connectivity for Apple CarPlay and Android Auto.
There’s also digital radio and enhanced functionality including an optional navigation upgrade with seven years of map updates.
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.
Our test vehicle is the 417CDI MWB (Medium Wheelbase) Panel Van with standard roof height, which comes equipped with a 2.0-litre, four-cylinder, turbo-diesel engine and nine-speed automatic transmission for a list price of $86,018.
Our example is fitted with a couple of factory options, including the 'Cargo Pack' ($2265) which comprises a two-passenger bench seat, solid cabin bulkhead with fixed window and side-entrance assist handle, wooden cargo bay load floor and floor-to-roof wall-trim using 5.0mm-thick wood panelling.
It also has optional 'High-Tech Silver' metallic paint ($2534) which combined with the Cargo Pack raises the total price to $90,817.
In addition to the latest model’s upgraded safety (see Safety) and comfort/convenience (see Design) features, our test vehicle comes standard with 16-inch steel wheels and 235/65 R16C tyres plus a full-size spare, keyless start, steering wheel paddles for manual shifting, multi-function leather steering wheel, three USB-C ports and two 12-volt sockets, side marker lights and heated exterior mirrors.
There’s also daytime running lights, a parking package with reversing camera and front/rear parking sensors, traffic sign assist, tyre pressure monitoring and lots more.
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 (OM654) 2.0-litre, four-cylinder, turbo-diesel, which meets Euro 6 emissions standards using AdBlue, produces 125kW of power at 3800rpm with peak torque of 400Nm served between 1700-2400rpm. The nine-speed torque converter automatic offers the choice of sequential manual-shifting using the steering wheel-mounted paddles.
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.
The dash display was claiming average combined consumption of 9.5L/100km when we stopped to refuel at the completion of our 281km test, of which about one third of that distance was hauling a heavy payload (see Driving).
Our own figure of 11.7 (based on actual fuel bowser and tripmeter figures) was higher but still reasonable economy for a vehicle in this GVM class in mostly urban use.
So, based on our own figures, you could expect a ‘real world’ driving range of around 800km from its 93-litre tank, which has been enlarged from 71 litres as part of the latest upgrades.
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.
Large handles on the doors and overhead shelves assist climbing aboard and there’s enough adjustment in the well-bolstered seat and leather-rimmed steering wheel to find a comfortable position.
Driver views from all angles are excellent thanks to well-designed mirrors along with cameras supported by active aids like blind-spot monitoring etc.
The cabin, with its high roof relative to seat height, has a spacious and airy feel and all controls are reasonably intuitive and easy to reach.
Unladen ride quality is surprisingly supple for a vehicle with a 6.0-tonne-plus GCM rating, combined with excellent steering feel that strikes a fine balance between minimal turning effort at low speeds (for loading etc) and firm handling response at higher speeds.
The drivetrain is also energetic, pulling strongly and cleanly from 1000rpm even though its maximum torque is tapped higher in the 1700-2400rpm zone. The automatic transmission has admirable refinement, with near-seamless shifting between its nine ratios.
The Sprinter is also impressively quiet at speeds up to 80km/h. Tyre and wind noise (the latter mainly around the large door mirrors) naturally increase at highway speeds, but remain far from intrusive. And with the engine requiring less than 2000rpm to maintain 110km/h, it’s well-suited to highway work.
To test its load-carrying ability, we forklifted 1.3 tonnes into the cargo bay which with driver equalled a payload of 1.4 tonnes. That's still almost half a tonne less than its limit.
Not surprisingly, it handled this load with ease, as handling and braking were largely unaffected and the ride quality became smoother thanks to such a big increase in sprung weight. Even so, the rear springs only compressed about 30mm.
It easily conquered our 13 per cent gradient, 2.0km-long set climb at 60km/h with this load onboard, as the auto downshifted to fourth gear to tap maximum torque when hauling this load to the summit.
Engine-braking on the way down, in a manually-selected second gear, wasn’t as robust but not unexpected given a 2.0-litre engine trying to restrain 1.4 tonnes of payload on a steep descent. Even so, the quartet of disc brakes efficiently kept speeds in check.
Overall, it was an impressive performance. However, we did note that the speed sign recognition function was not working for the duration of our test. And some welcome enhancements would be a driver’s left footrest and a fold-down inboard armrest for the driver’s seat, as fitted to its smaller Vito sibling.
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.
ANCAP ratings do not apply to Heavy Commercial vehicles. Even so, in addition to the Sprinter’s existing long menu of passive and active safety features, the latest range adds significant enhancements as standard equipment including thorax-protecting airbags for driver and passenger, lane-keeping assist, traffic sign assist, rain-sensing wipers, tyre pressure monitoring and a parking package with reversing camera and front/rear sensors.
Also new is ‘Moving Off Information Assist’ which utilises a camera mounted in the grille plus six ultrasonic sensors to monitor an area 3.7 metres in front of the steered direction of the vehicle and 0.5 metres to the side.
This automatically activates at start-up and remains active up to 10km/h. So, if a road user is detected in the monitored area, the driver is alerted by audible and visual signals.
The latest range also introduces ‘Sideguard Assist’ which provides extended detection in the blind-spot on the passenger side. It activates when the vehicle is stationary and at low speeds, providing an extra set of eyes during parking, low-speed manoeuvring and traffic congestion.
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.
Warranty is five years/250,000km whichever occurs first and includes a roadside assist support package.
Scheduled servicing is every 12 months/40,000km. Pay-as-you-go capped-pricing for the first five scheduled services totals $5905, or a pricey average of $1181 per year. Service plans are also available.
