What's the difference?
The RAM 2500 from RAM Trucks Australia, which is rated to tow nearly 7.0 tonnes, is designed primarily as a heavy duty towing platform with a huge Cummins turbo-diesel engine, long wheelbase, high kerb weight, exhaust brake and lots of room inside a luxurious cabin.
These 'Australianised' RAM trucks are shipped in a unique export specification direct from Fiat Chrysler Automobile's heavy duty RAM Trucks Saltillo assembly plant in Mexico, re-manufactured in RHD on a bespoke production line in Melbourne and distributed throughout Australia and New Zealand by American Special Vehicles.
ASV is a joint venture between Ateco Automotive and the Walkinshaw Automotive Group (WAG) which also owns Holden Special Vehicles. It is the only RAM Trucks importer in Australia officially sanctioned by FCA, resulting in a unique factory-approved vehicle that meets the company's strict OEM standards and is backed by a full factory warranty and national dealer network.
Put simply, it's as close as you can get to driving a brand new RHD version of this legendary American pick-up off FCA's Mexico assembly line, and offers a compelling solution for those with something really big to tow.
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?
The RAM 2500 Laramie 4x4 is designed primarily as an extreme duty tow vehicle, and in that role it excels. So if you've got something really big to tow like a multi-axle caravan, horse float, boat trailer or other type of trailer up to 7.0 tonnes, you'd be hard pressed to find a more effortless and luxurious way to move it than with one of these jiggers.
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.
With a granite-crushing 3577kg kerb weight (by comparison Ford's top-shelf Ranger Wildtrak dual cab ute is 'only' 2250kg) the RAM 2500's architecture is tailor-made for heavy towing with a massive ladder frame chassis and expansive 3797mm wheelbase (Ranger 3220mm) providing rock-solid towing stability.
Front and rear suspension is via multi-link coil-sprung live axles (LSD rear), with four wheel disc brakes inside 18 x 8.0-inch polished alloy wheels and Michelin LT265/70R18E all-purpose tyres. Plus there's a full size spare.
ASV prefers to use the word 're-manufacture' rather than 'conversion' when describing its extensive body-off-frame RHD engineering process. We can vouch for that, having inspected the company's ISO quality-certified Melbourne production line, which turns out about 40 vehicles a month and employs 28 full-time staff in a dedicated factory right next door to HSV in Clayton. The end result is OEM standards in parts supply, engineering quality, standard of finish and driving performance.
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 RAM 2500's payload capacity of 913kg might seem conservative compared to smaller dual cab utes with one-tonne payloads, but drill down further into its huge tow ratings and that 913kg (say 5-6 occupants and all their gear) looks mighty impressive.
Why? Because on a 50mm ball it can tow up to 3500kg with a full payload (7990kg gross combined mass), on a 70mm ball it can tow up to 4500kg with a full payload (8990kg GCM) and with a gooseneck and ring connection (aka pintle) it can tow up to 6989kg – and still with a full payload. That's a whopping 11,479kg GCM or just under 11.5 tonnes. Try doing that with a one-tonne ute!
The heart of this power giant is a Cummins 6.7 litre inline six cylinder turbo-diesel with 276kW at 2800rpm and a towering 1084Nm of torque at only 1600rpm.
The big cargo box, which is protected by a spray-in bedliner, is 511mm deep with a load floor that's 1939mm long and 1687mm wide with 1295mm between the wheel arches. That means it can take a standard 1160mm x 1160mm pallet, or a couple of dirt bikes with the tailgate up and heaps of room left for your gear and tools.
The cabin offers numerous storage options with bottle holders and twin storage pockets in the front doors, a huge centre console (which pivots into an upright position to serve as the centre seat backrest when required) with internal storage and three more cup/bottle holders, twin glove box compartments, rear door storage pockets, a central floor-mounted twin bottle holder and deep in-floor storage bins hidden under the carpet mats on either side. The rear seat can also be quickly reconfigured into a convenient flat-floored cargo area when required.
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.
ASV offers a choice of 2500 and 3500 (larger GVM) models, with the 2500 attracting the vast majority of local sales as it has a higher peak tow rating and can be driven with a standard driver's licence.
Our test vehicle was the RAM 2500 Laramie Dual Cab 4x4 which starts at $139,500. That's a lot of money but not unreasonable when compared to the $120,000-plus you'll pay for Toyota's local towing hero, the 200 Series Land Cruiser in premium Sahara spec, with 'only' a 3.5 tonne tow rating.
The ASV RAM is supplied in top-shelf Laramie grade which includes a sumptuous six-seater leather interior with more features than you could ask for. These include all the usuals like multimedia interface, dual-zone climate control, sunroof, sliding rear window and power everything, plus some not-so-usuals like remote starting using the key-fob (great on cold mornings before you leave the house), a high-mount cargo camera to keep an eye on your payload, a heated steering wheel and power adjustable pedals to name a few on a very long list.
Further proof of its intended role in life is a seven-pin wiring harness, heavy duty receiver hitch and electric trailer brake control. In simple terms, it's fully loaded.
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.
The heart of this power giant is a Cummins 6.7 litre inline six cylinder turbo-diesel with 276kW at 2800rpm and - most importantly in this context – a towering 1084Nm of torque at only 1600rpm. It's also equipped with a very effective exhaust brake with a choice of settings.
Chrysler's equally robust and well-proven (68RFE) six-speed automatic transmission with driver-adaptive shifting is purpose-built for extreme duty. The 4x4 drivetrain features a dual-range Borg Warner transfer case with electronic shift-on-the-fly control and a 2.64:1 low range reduction, which with the 3.42:1 final drive results in a 29.2:1 crawl ratio. Ideal for towing a heavy load out of a rugged worksite or a campground turned boggy by overnight rain.
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.
We conducted two tests based on fuel bowser and trip meter readings. The first, which mostly comprised heavy towing, resulted in 20.14L/100km compared to 16.6 on its instrument display. The second was a mix of city, suburban and highway driving with no towing which returned 15.08 litres/100km compared to 14.0 displayed.
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.
The strong whiff of leather is a nice way to start each journey. The full-length side steps and grab handles are required for every climb in and out of the elevated cabin which provides a commanding view of the world, even though the outer edges of its vast bonnet and front mudguards disappear from view.
The front seats are wide and comfortable with good lateral support and rear seat passengers have generous head, shoulder and legroom as you would expect. Although it feels huge when you first climb aboard, the RAM starts to shrink around you the more you drive it, aided by front and rear parking sensors and a reversing camera for tight parking situations (which is most of the time).
Its height of 1974mm (Ranger 1848mm) will still clear most undercover car parks (usually 2100mm limit) and its 2009mm width is only 150mm wider than a Ranger, so it will also fit within most car parking spaces. The biggest parking handicap is its oil tanker-like 6030mm length which is 675mm longer than the Ranger, so you need plenty of room for reversing.
On the highway it has a remarkably quiet cabin environment thanks to substantial ASV-added sound insulation, low wind noise and minimal tyre roar.
Ride quality when empty is generally good, although you do notice the firmness of the heavy duty spring rates over larger bumps. Acceleration is spirited, too, with an unbridled 1084Nm shoving you in the back and the steering is nicely weighted and relatively direct for an old-school steering box set-up.
The quartet of disc brakes, though, do not have the bite relative to pedal effort one might expect. ASV engineers claim it's the result of pad compounds which have to withstand the heat of up to 7.0 tonne towing loads, so they tend to be relatively hard.
On the highway it has a remarkably quiet cabin environment thanks to substantial ASV-added sound insulation, low wind noise and minimal tyre roar. At 100km/h with no payload, the 6.7 litre Cummins barely ticked over at 1400rpm and that hardly changed when we hooked up a dual axle New Age Caravan with a 3270kg tare weight.
Given that was less than half of its peak towing capacity, the big RAM barely noticed it was there. The engine's massive 1084Nm of torque at only 1600rpm was most impressive on long gradual climbs, allowing the truck and caravan combo to squash each hill in top gear with minimal throttle.
Each time you ease off the accelerator, too, the exhaust brake provides more than enough retardation (and Kenworth sound effects) to ensure you rarely need to push the brake pedal. And when you do, the electric trailer brake control provides powerful and sure-footed stopping power. The door mirrors were also wide enough to see along each side of the van and approaching rear traffic.
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.
Currently no ANCAP rating but ASV subjected one to a full frontal barrier crash under Australian Design Rule 69/00 which it passed, thereby becoming the first locally converted (oops, re-manufactured) vehicle to be crash tested.
It's loaded with passive and active safety features including driver and front passenger airbags, front seat-mounted side airbags and front and rear side curtain airbags, electronic stability control, front and rear parking sensors, tyre pressure monitoring display and reversing camera. The rear seat has three headrests and three lap-sash belts plus anchorage points to secure up to three child seats.
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.
RAM Trucks Australia provides a three year/100,000km warranty plus national Roadside Assistance for the duration of the warranty period.
Service intervals of six months/12,000km whichever comes first. ASV has a 30-strong Australian dealership network providing full sales and after-sales service.
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.
