RAM 2500 vs GWM Tank 300

What's the difference?

If you're a grey nomad with a massive caravan searching for something to do the big lap in, or a big boater seeking an effortless weekend getaway machine, then this sort of ute makes sense. The HD series shows just how much more muscle is available, for those who genuinely need it.

But if towing or hauling to the max isn’t your priority, then the far-more dynamic – and class-leading – Ram 1500 series does everything else with much-greater aplomb.

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

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.

You can spot the HD facelift by the bi-LED headlights and bulgier bonnet, while chrome’s been replaced by black trim inside and out, including in the restyled grille, alloy wheels and side steps, for a more-modern appearance.

Both models are identical bar the badging. However, while they share a tri-link solid front axle system, the 2500 HD features coil-spring rear suspension, while the super heavy-duty 3500 HD relies on leaf springs. That’s for it to achieve maximum pulling and hauling capability.

Inside, the already-contemporary dashboard, with its 12-inch Tesla-esque portrait touchscreen, remains much the same as before, except for a few detail updates to accommodate the big new centre console, twin wireless charger housings, extra USB ports and restyled electronic instrument cluster.

Otherwise, it’s as vast as ever.

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.

As with all Walkinshaw Automotive Group utes (that includes the Silverado), the Ram HD’s fit and finish seem exemplary, with an insider suggesting the quality may exceed the North American factory original.

This is no small feat. Ateco Automotive, the instigator and original importer of over 35,000 (and counting) remanufactured left-hand to right-hand-drive DS, DT and DJ full-sized utes in Australia since the first 2500 HD rolled off the Melbourne production line in 2015, says “between 400 and 500” unique engineering pieces are necessary.

Compared to the pre-facelift versions, the DJ Series II sees a switching out of the old front bench seat, which meant the earlier versions were six seaters, to shapelier individual items. Apparently, comfort and convenience are what buyers prefer, since a large centre console with armrest is now included. It’s certainly seems plush and luxurious inside.

Along with greater storage, the Ram’s electronic instrumentation is new and the multimedia system has been updated, with extra USB ports as well as twin phone chargers.

The driving position might be compromised for some by a lack of reach adjustability for the steering column (unlike in the DT 1500), and the foot-operated park brake seems like an anachronistic nowadays, but otherwise everything is easy to reach and operate – despite being scattered all about – after you’ve learned what all the buttons and switches do.

Meanwhile, the now-fixed seats can accommodate a trio of burly occupants no problems due to the sheer width of the cabin.

Included are air vents, extra USB ports, a sliding back window and storage underneath the seat cushions and within a special floor compartment.

Owners can also create a raised floor section, by tilting both cushions up and folding down two corresponding bases for a flat and even load area, with additional hidden storage within the now-covered footwells.

Overall, the Ram’s cabin balances convenience and utility quite well.

Further back, the tub length is 1938mm, width is 1687mm and 1295mm between the wheel arches and height is 511mm. This compares to the Silverado 2500’s superior corresponding figures of 2089mm/1814mm/1317mm/533mm, respectively.

A swing-away step is provided to help tub access, as well as a spray-in bedliner, strut-assisted tailgate-close and 12-pin towbar fitted as standard.

Maximum towing capacities vary from 3.5 tonnes to an unmatched eight tonnes with the correct accessories. The 2500’s payload is 785kg while the 3500 more than doubles that. And standard exhaust brakes help with braking on long descents when fully laden.

Which brings us to the heart of the matter. Muscle.

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.

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.

Under the now-bulgier bonnet may be the torquiest engine money can buy, at least in something that does not require a special driving license. Or pilot's licence.

Completely overhauled with a redesigned engine head, larger intake and exhaust valves, a new turbo, heavier-duty pistons, a higher-pressure fuel system and upgraded intake manifold amongst other changes, the Cummins-sourced 6.7-litre in-line six-cylinder turbo-diesel unit now delivers 313kW of power at 2800rpm and 1458Nm at 1800rpm.

Formerly making 276kW and 1152Nm, the new figures are 13 per cent and 26 per cent better than before (respectively), reducing the power gap with the Silverado’s 350kW/1322Nm 6.6L V8 turbo-diesel, while easily leap-frogging it for torque.

At 3710kg (kerb), the HD’s power-to-weight ratio improves significantly despite putting on about 100kg, from 76.5 kW/tonne to 84.4kW/tonne.

Meanwhile, a ZF-supplied eight-speed auto replaces the old six-speed unit. It’s now a second faster to 100 at under 7.3 seconds and the spread of extra gears should improve highway fuel consumption, albeit slightly.

Drive is sent to the rear wheels in two-wheel drive (2WD) mode in most cases. However, 4WD High (4H) is also available via a part-time dual-range transfer case and is selectable on-the-fly, though it is not recommended for operation above 80km/h, while 4WD Low (4L) is for rougher terrain at very low speeds.

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.

Ram says the Australian Government doesn't mandate an official combined fuel consumption figure for full-sized utes like these, so there is no average economy number for us to share.

But the trip meter in two of our test vehicles said it consumed between 15 litres per 100km and 15.6L/100km of diesel fuel, and both had not been towing a trailer or load since being reset.

Despite the new ZF eight-speed auto’s revised final drive ratio (now 3.42:1 instead of 3.73:1) to help improve efficiency, clearly this is no Toyota Prius.

Based on those trip computer numbers, expect the 117-litre fuel tank to provide about 760km between refills. Handily, the 28.4L AdBlue reservoir comes with its own tank display on the dash.

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 Ram HD’s column shifter and foot-operated park brake say it all. This is a big, floaty and, at times, old-fashioned American truck, and that is certainly how it feels from behind the wheel.

2500 HD first.

From the initial burble of the forced-induction in-line six diesel, you can feel the torque simmering restlessly within. Slot the awkward selector into Drive, and – depending on how much heft you’re hauling – the Ram will lurch off the line like a startled bull, and before you know it, you’re bounding along.

If lightly laden, you’ll even momentarily spin the rear wheels in the lower ratios – second (the start-off gear; first’s for lugging only), third and maybe even fourth if the surface is slippery enough, though the traction controls will quell anything more than a bit of a bum wiggle.

From there on in, on a straight piece of highway anyway, the 3.7-tonne ute just strides along effortlessly, picking up the pace with ridiculous ease as required. You’re soon aware that the cruise control is vital if you’re going to keep your licence.

If you’re wondering how different the HD feels compared to the related regular Ram 1500, the first corner will serve up some answers soon enough.

The steering is light and reassuringly measured in response, but also numb and less precise than expected, if not quite vague, meaning you need to feed in inputs carefully. Especially at speed. Rushing it in, or blundering through a tighter turn carelessly, will have the laws of physics reminding you of this truck’s length and girth, and not to mention maybe the long arm of the law on your tail as well before long. Anyway, other road users will soon let you know as well. Take it easy.

Over the varied and at-times tight rural roads of Victoria’s Gippsland region, the endless pitter-patter of the unladen suspension, combined with the constant pitching from the body and trigger-happy brakes, resulted in motion queasiness, if not sickness. We’ve been assured that with a load as intended, everything including our internal sense of balance should settle down. Which makes sense. A boat or caravan out back should provide the anchoring effect required.

Back on straighter and smoother ground, where the 2500 smothers and smooshes most things before it, you’ll be glad for the commanding vision aided by the massive mirrors and surround-view cameras, helping to boost driver confidence, particularly when weaving through traffic or in parking scenarios.

But the compromises demanded for the ability to haul up to eight tonnes means this is a very niche proposition.

Which is why Ram insisted on us testing the sole 3500 HD with a 3.5-tonne caravan hitched out back, on the ex-Holden speed loop at Lang Lang.

This was a test of acceleration and control, and – again – we managed to spin the rear wheels in the lower gears.

Likewise, all that torque was delivered without struggle or strain, and almost immediately the 3500 was sitting steadily at 110km/h. The planted chassis and various electronics seamlessly kept everything in line.

But the track surface was too calm to assess the ride comfort from the leaf-sprung suspension, and we weren’t allowed to venture on to public roads.

Returning back to base, we even forgot all about the caravan quietly shadowing our every move out back, which is a sign of the 3500’s towering towing confidence.

Which is exactly what it says on the tin.

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.

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.

So, here's where the news may not be so good for potential HD buyers, because the Ram’s warranty is well below its main competitor.

Now it is the sole US full-sized ute with a three-year, 100,000km warranty, instead of the five-year/unlimited-kilometre coverage offered by the others.

And don’t forget, this is the era where (albeit smaller) utes from Kia have seven years while Mitsubishi, Nissan and MG are up to 10 years (conditionally).

Service intervals are at just six months or 12,000km and there are no capped-price servicing options either.

As a result of trailing the competition so badly in these key areas, the Ram HD’s overall rating has been dragged down significantly.

Along with the 75 Ram dealers throughout every state and territory in Australia, there are an additional three garages that will service the vehicles.

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.
