Before the 1980s, when air travel was expensive, the humble Australian family car had to be able to tow a big boat or caravan in order to take the brood on holidays across our vast, sunburnt land.

Many turned to oversized American barges, like the Dodge Phoenix and the Pontiac Parisienne. People loved their massive dimensions, huge interiors, endless torque and look-at-me status.

And guess what? They still do. And even the same carmakers remain today, thanks to Chrysler’s Ram 2500/3500 Heavy Duty (HD) – which grew out of Dodge – and General Motors’ Chevrolet Silverado 2500 HD.

• 76kW 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.

Efficiency – What is its fuel consumption? What is its driving range? 6 / 10

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.

Driving – What’s it like to drive? 7 / 10

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.

2026 Ram 2500 HD

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.

Safety – What safety equipment is fitted? What is its safety rating? 7 / 10

Neither ANCAP nor Euro NCAP have tested any full-sized American utes at this stage.

However, the 2500 HD is alone in its class in having a National Highway Traffic Safety Administration rating for 2025, scoring four out of five stars.

For the Series II upgrade, the autonomous emergency braking system now includes cyclist and pedestrian detection and braking, the traffic-sign recognition tech is new, whilst rear-cross-traffic alert, blind-spot monitoring, a 360-degree view camera and tyre-pressure monitors continue. No operation parameter data for the AEB is provided.

Plus, dual front, front side and curtain airbags are fitted, along with three child-seat restraining top-tether points and a pair of ISOFIX latches in the rear outboard seats.

Ownership – What warranty is offered? What are its service intervals? What are its running costs? 3 / 10

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.

Verdict

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.
