What's the difference?
Ford’s legendary F-Series has been America’s best-selling truck for more than four decades. A major factor in that success is the Super Duty range (F-250/F-350/F-450), which reports for duty when loggers, landscapers, miners, oil-field workers and anyone else with seriously heavy on- and off-road load-hauling requirements needs more than the entry level F-150 can deliver.
Not surprisingly, such extreme-duty towing is also required in Australia, particularly by tradies with heavy equipment, and/or for recreational and sporting pursuits that involve multi-axle caravans, horse floats, boat trailers and the like. Some of these large trailers feature a goose-neck design which requires a prime mover-style turntable coupling mounted in the cargo tub.
There are a number of small volume importers which cater for these specialised requirements, including Harrison F Trucks at Melton in Melbourne’s outer west. Harrison provides ADR-approved right-hand drive conversion, local certification and sales/after-sales service for these American giants, one of which we recently sampled for a few days to see what life is like in the world of the Super Duty.
If you're in the market for a premium-style four-wheel drive wagon with eight seats and a petrol V8 engine and you live in Australia, your choices have been rather limited. You'd be looking at something like the Nissan Patrol or the Land Rover Defender 130.
Well, that has now changed as General Motors Specialty Vehicles (GMSV) is importing the GMC Yukon Denali to Australia. This top-of-the-range Yukon arrives here as a left-hand drive vehicle and is converted to right-hand drive at a facility in Victoria to suit our market.
The Denali has a price tag just under $175,000, though, and that makes it a lot more expensive than most vehicles that could be considered rivals in the Aussie market. Is it worth it?
Read on.
If you’ve got something really heavy to tow and you have the budget to do it in grand style and with minimal effort, then a Super Duty could be just what you’re looking for. Its gargantuan proportions make it impractical for daily driving in Australian city and suburban traffic, but as a heavy-duty tow vehicle, particularly for long-haul open highway work, you’ll feel like king of the road.

The 2025 GMC Yukon Denali is a big, comfortable, eight-seat 4WD with few rivals in the Aussie market. However, while it may occupy its own niche, it doesn't offer enough in terms of premium look and feel and towing capacity over what could be considered its rivals – and it all comes back to that price tag.
While it lacks a competitive warranty and its price puts it way out of reach of a lot of 4WD buyers, if you are in the market for a big premium-style wagon with a V8 and eight seats – and the Nissan Patrol and Land Rover Defender 130 aren’t your cup of tea – then the Yukon Denali just might be the right choice for you.
But when all is said and done, for the price of the Denali, you could buy two Nissan Patrols – maybe not brand-new ones – and a camper trailer and a couple of cartons of beer.
Needless to say, the MY18 F350 Super Duty 4x4 is a monster, even in this SWB specification. The massive 4059mm wheelbase is 839mm longer than a Ranger Wildtrak, which is also dwarfed by the Super Duty’s 6350mm overall length (961mm longer). The F-Series’ 2032mm width is 182mm wider than the Ranger, and its 2065mm height is 217mm taller. It's like a Ranger that's been fed heaps of fertiliser.
Underneath is the kind of heavy-metal hardware needed to justify a Super Duty badge. Ford claims its massive fully-boxed steel ladder-frame chassis is up to 24 times stiffer than the previous generation, along with improved corrosion resistance. The cargo tub is made from military-grade aluminium with the dual benefits of less weight and no rust. A tough spray-on cargo tub liner boosts dent and weather protection.
Live axles are used at both ends, suspended on huge leaf spring packs at the rear and softer-riding coils up front. Steering and four-wheel disc braking are both power-assisted, of course, and there’s a choice of trailer-towing hitches available.
As you would expect, cabin space for both front and rear occupants is palatial, with even tall adults feeling dwarfed by its enormous dimensions. Rear passenger leg and shoulder room even for tall adults is limousine-grade, although headroom is reduced (but still adequate) due to the lower roof lining surrounding the full-length sunroof.
The overall fit and finish of the dashboard, following Harrison’s local RHD conversion process, displays quality workmanship. However, some DNA from its Kentucky birthplace remains in the control screen’s software, which, for example, displays 911 Assist instead of 000, and a left-side driver’s seat icon for the massage control. We also noticed that the AM radio station display only moves in 10kHz increments without the ability to tune between them (too bad if you like talkback).
There’s also no driver’s left footrest and the parking brake pedal seems overly high, requiring the raising of your left knee above steering-wheel height to get your boot on it.
The 2025 GMC Yukon Denali is 5337mm long (with a 3071mm wheelbase), 2378mm wide, 1943mm high and has a kerb weight of 2813kg.
Suffice it to say, it’s big.
The signature Denali grille – with LED headlights and chrome accents – is the size of a house and it’s eye-catching.
In terms of design, the rest of the Denali is standard SUV, but it's so massive it can't help but have plenty of presence on the road.
This 4WD has 24-inch rims, which are not suited to off-roading at all, but I’ll get to that later.
The Denali’s dual exhaust system, with polished stainless-steel tips, adds to the street-cool aesthetic.
The rest of the Denali exterior works – but it’s an in-your-face kind of success.
Inside, the space is cavernous and with leather upholstery, wood-look trim and soft-touch surfaces you’d expect it to feel like a plush, well-appointed cabin. But it doesn’t quite hit the mark.
Sure, all three rows of seats offer enough in terms of comfort and amenities but, for a $175,000 vehicle, the cabin lacks a distinctive premium feel, as you'd assume it should in a vehicle at this price point. That's a bit of a disappointment.
Our F-350 test vehicle with its F-250 downgrade results in a 700kg decrease in both payload and tow ratings. In other words, based on Harrison’s figures, in full F-350 specification it has a 1700kg payload capacity and 9700kg GCM, which means it can legally tow up to 4510kg of braked trailer with a full payload or up to 6210kg without. In our F-250 form it offers a 1000kg payload with 9000kg GCM, and can legally tow up to 3810kg of braked trailer with a full payload, or 4810kg without.
The huge cargo tub has a load floor length of 2080mm and width of 1700mm, with 1283mm between the wheel arches allowing ample room for a standard 1160mm-square Aussie pallet. There’s a total of eight tie-down points, overhead and internal lighting plus key fob operation of the tailgate, which houses a handy fold-out step and grab handle for easy cargo tub access.
The sumptuous cabin has plenty of storage options, including a single glovebox, and a bottle holder and two storage bins in each front door. The centre console has an open storage cubby at the front, another open storage bin and two bottle holders in the centre, a cavernous box behind that with a padded lid which doubles as a comfortable armrest, and two more bottle/cup holders at the back.
Those in the rear seat also get a fold-down centre armrest with two pop-out cup holders and each rear door has a bottle holder and two storage bins. There are also flexible storage pockets on the rear of both front seats and the 60/40-split rear seat base cushions swing up through 90 degrees and lock into position, revealing a huge full-width storage area underneath.
The Denali has retractable sidesteps, which is a big help to hobbits, such as me, and it also has big grab handles, again a welcome addition for the purposes of easier ingress for those on the wrong side of tall.
Once you climb inside, it’s easy to appreciate the fact that this wagon’s interior is vast, functional and comfortable, with plenty of storage spaces for everything – glove box, centre console, sunglasses case, door pockets etc – and plenty of charge points for your array of smart devices, even a wireless charge pad.
It’s a well-designed cabin but, as mentioned earlier, the Denali lacks the prestige fit and finish and even build quality usually showcased in something at this price-point.
Instead, there are expanses of hard plastic throughout, storage receptacles with flimsy lids, and lacklustre fit and finish here and there.
The vertically-oriented 16.8-inch touchscreen multimedia system is simple enough to use, even when the road gets bumpy, although it sometimes took a few stabs of my finger to get the system to register a command.
Climate control switches and the like are located under the screen.
The three rows of seats offer more than adequate levels of comfort – the front seats are heated and ventilated and the second row’s outboard seats are heated – and each row also has the appropriate amount of amenity to suit its occupants, including cupholders, USB-C sockets, map pockets and the like.
The second-row seats even have 12.6-inch HD colour touchscreens – one on the back of each front-row headrest – with which to enjoy… whatever. Those units also have wireless headphones so everyone else in the vehicle doesn’t have to listen to… whatever.
Those in the third row get air vents, a USB-C plug and two cupholders on both sides.
Rear cargo volume with all seats up is 722 litres. With the second row folded that number expands to 2056 litres, and with only the front seats left standing you have a 'yuge' 3480 litres to play with.
The boot area has tie-down points, a shallow section of underfloor storage and plenty of packing potential. The tailgate door is power-assisted with remote open and close.
As I mentioned, the Denali’s interior is very functional and very comfortable and that includes the second and third row, which offer plenty of space.
Overall, my thoughts on the Denali’s cabin interior boil down to “massive”, “comfortable” and “feels cheap”.
Our test vehicle was the MY18 F350 SWB Crew Cab Platinum 4x4 pick-up, downrated to a 4490kg GVM rating (same as the F-250) to allow it to be driven with a normal car licence. According to Harrison, Ford achieves this by simply removing an additional booster spring and block in the rear suspension, resulting in the lower ratings. It was also fitted with Ford’s FX4 off-road option (rear diff lock, skid plates, special shocks, hill-descent control), bringing the drive-away price to an eye-watering $165,990.
The Platinum is one of six grades in the Super Duty range, and one of three only available in the Crew Cab, in which it represents the middle tier above King Ranch and below Limited. Although Harrison can import most of the Super Duty model grades, it claims the Platinum delivers the best ‘bang for buck’ in terms of features and trim level, riding on stylish 20-inch polished alloy wheels and LT245/75Rx17E all-terrain tyres with a full-size spare.
As you can imagine, the sumptuous Platinum has power everything and is loaded with features that are way too numerous to list here. Suffice to say, everywhere you look there’s conspicuous luxury, from the moment the concealed power-operated side-steps smoothly extend when you open the door, and then retract when you close it.
Inside is an 8.0-inch touchscreen for the SYNC3 voice-activated infotainment system with multiple connectivity options, including Apple CarPlay and Android Auto, premium leather seating (with heating, cooling and even massage for the front seats), a full-length panoramic sunroof, huge power-extendable door mirrors for towing (with built-in courtesy lights), power adjustable pedals and steering wheel (which is also heated), remote-opening tailgate with fold-out step, cameras everywhere for 360-degree coverage and even a wide choice of changeable colours for the ambient cabin lighting.
We could go on, but you get the picture. It’s magnificent excess in the true US tradition, where too much is never enough.
The 2025 GMC Yukon Denali is a top-shelf, eight-seat, 4WD V8-powered wagon with a price-tag of $174,990, before on-road costs.
The standard equipment list is a comprehensive and its more notable features include a 16.8-inch touchscreen multimedia system (with wireless Apple CarPlay and Android Auto - but no sat-nav), a 14-speaker Bose sound system, power-adjustable heated and ventilated leather-accented seats, a head-up display, 12.6-inch rear HD touchscreens for the second-row passengers, a panoramic sunroof and an auto-sense power rear door.
It also has a 360-degree high-definition camera system (with up to 11 camera views), power-retractable sidesteps, 24-inch machined and painted 'pearl nickel' alloy wheels (on Bridgestone all-season tyres), all-around adaptive air suspension and a maximum braked towing capacity of 3628kg (when it has a 70mm ball and weight-distribution hitch).
Exterior paint choices include 'Onyx Black', 'Summit White', 'Titanium Rush Metallic', 'Volcanic Red Tintcoat' (on the test vehicle and costs $2000), 'Downpour Metallic', 'White Frost Tricoat' and 'Sterling Metallic'.
The F350 Super Duty is powered by Ford’s common rail 6.7-litre Power Stroke V8 turbo diesel, which, with four valves per cylinder and variable vane turbocharger, punches out 335kW at 2800rpm and a massive 1267Nm of torque at only 1800rpm.
The SelectShift six-speed automatic transmission is also designed and built by Ford. Its triple-plate, two-stage torque converter offers full lock-up capability as low as 900rpm, and there’s a dedicated tow/haul mode which avoids unwanted shifts on climbs and provides powerful engine braking on descents.
The exhaust brake can also be manually selected. The 4x4 system is part-time dual-range, with auto-locking front hubs and shift-on-the-fly engagement.
The GMC Yukon Denali has a naturally-aspirated 6.2-litre V8 petrol engine – producing 313kW and 624Nm – and that’s matched to a 10-speed automatic transmission.
This is an impressive set-up – the Denali is punchy off the mark, smooth and refined at highway speeds and overall it offers a composed and comfortable driving experience.
The Denali has a full-time 4WD system, selectable driving modes include 'Normal', 'Sport', 'Off-road' and 'Tow' and an electronic limited-slip differential is standard.
Flick through a Super Duty sales brochure and you won’t find any reference to fuel economy ratings. However, for what it’s worth we crunched some figures at the end of our relatively short 200km test based on trip meter and fuel bowser readings, resulting in a reasonable 15.8L/100km.
That’s not far away from the dash read-out at 14.2, so with its big 130-litre fuel tank you could expect a driving range of around 820km.
Obviously, with such a big vehicle – almost three tons – driven by such a big V8 engine, fuel consumption is a concern. The 2025 GMC Yukon Denali has a listed fuel consumption figure of 12.8L/100km (on a combined, urban/extra-urban cycle).
I recorded 16.2L/100km on this test. I did a lot of high- and low-range 4WDing and this wagon was never working hard.
The Denali has a 91L fuel tank so, going by my on-test fuel-consumption figure, you could reasonably expect a driving range of about 560km from a full tank.
You sit up nice and high in very comfortable seats, with a commanding view of surrounding traffic and the road ahead. We quickly adapted to the width and height of the Super Duty, but the major issue in city and suburban driving was its oil-tanker length, which required later turn-in on tight corners to provide kerbside clearance. We also needed to check that there was ample reversing room when choosing a space in a parking lot, to ensure we didn’t get wedged when trying to leave.
With the big turbo diesel V8’s 1267Nm of torque being tapped at only 1800rpm, it provides spirited getaways from traffic lights, and easily keeps up with normal city and suburban traffic flow with your big toe barely touching the accelerator pedal.
The ride quality without a load is quite good on smooth surfaces, with its massive 3.5 tonne kerb weight feeling like the tyres are leaving indents in the bitumen. However, over rougher roads and larger obstacles like speeds humps, it starts to bounce around more and can feel quite ponderous at times. However, this is to be expected in an empty vehicle with such high payload and tow ratings.
The steering is surprisingly direct and firm in feel. It’s also quite linear in turning weight regardless of road speed, without the more noticeable changes evident in its little brother Ranger, which is very light at parking speeds but gets noticeably firmer as speeds increase.
Braking is reasonably responsive but like other giant US pick-ups we’ve tested, you have to get them quite hot to make them really bite. That’s because their pad compounds tend to be on the hard side, given they have to cope with the high temperatures generated by heavy-duty towing.
The engine exhaust brake is surprisingly quiet and very effective at slowing the vehicle, aided by more aggressive downshifts in the six-speed auto.
The Denali is imported to Australia as a left-hand drive vehicle and then Walkinshaw's subsidiary company Premoso remanufactures the US 4WD wagons to right-hand drive at their facility in Clayton, Victoria.
And that mob has done a commendable job.
Firstly, the Denali is very impressive on general driving duties – settled and composed, that V8 just rumbles along. It’s pretty close to flawless on the open road - smooth and refined.
But off-road is a different story – especially in low-speed technical low-range 4WDing – and a lot of that has to do with the Denali’s sheer bulk and its 24-inch wheels.
The big pizza plate rims and paper-thin Bridgestone all-season tyres (285/40) aren't suited to four-wheel driving as they don’t offer the grip of a decent all-terrain and you can’t drop air pressures because there isn’t enough tyre there. Worth noting the spare is a Maxxis Bravo HT-750 (265/70R17).
In its favour, though, the Denali has a range of drive modes – one of which is Off-road and that seems well calibrated for a variety of 4WD situations – as well as high- and low-range gearing and an electronic limited slip diff.
Steering has a nice balance to it at low speeds, throttle response is quite impressive and controlled. And you can call on that 624Nm from the big 6.2-litre V8 pretty much as you see fit, and it delivers it smoothly and in a controlled fashion.
This top-shelf variant has air suspension – that does some levelling out of even major imperfections in the road or track surface – and it does have a special damper system also working away to even out ride and handling.
In terms of off-road measurements, the Denali offers approach, departure and rampover angles of 24.8 degrees, 20.5 degrees and 22.5 degrees, respectively.
Ground clearance is listed as 205mm, wading depth is not quoted, but likely a guesstimated 700-800mm, and turning circle is 12.4m.
And again, this is a big vehicle – 2813kg – so it requires more consideration, more patience, more skill and probably more experience than perhaps some smaller four-wheel drives do.
The Denali's payload is listed as 634kg, which is not a lot for a massive vehicle like this. Its towing capacities are 750kg (unbraked) and 3500kg braked.
If you do, however, put a 70mm tow ball and a weight-distribution hitch on the Denali, you can tow as much as 3628kg legally (braked).
That's not a lot more than something like the Nissan Patrol, which is 3500kg, or the equivalent 4WD wagon or ute available in Australia already. So the extra towing capacity in the Denali is not that big of a selling point. GVM is 3447kg and GCM is 6577kg.
Ultimately, even though the Denali has sound four-wheel drive mechanicals and reasonable off-road traction control, it's hampered by its gargantuan dimensions and let down by its 24-inch wheels and paper-thin tyres.
If you got rid of the standard wheel-and-tyre combination and replaced it with a set of decent, aggressive all-terrain tyres on 17 inch or 18 inch, or even (if you had to) 20 inch wheels, those changes would go a long way to making this over-sized 4WD capable in some off-road scenarios.
In its current state, however, the Denali is a tow vehicle playing at 4WDing rather than the other way around.
No ANCAP rating, but for what it’s worth the 2017 F-250 Super Duty SuperCab and Crew Cab 4x2 models earned the US government’s highest five-star safety rating. Passive safety includes driver and passenger front and seat-side airbags plus side-curtain airbags. All three rear seat positions have top tethers for child seat restraints but no ISOFIX.
Dynamic safety does not include AEB, but there’s adaptive cruise control and collision warning with brake support, (BLIS) blind spot information system with trailer coverage and cross-traffic alert, lane-keeping alert, reverse sensing system, rain-sensing wipers, automatic high beam headlights, hill-start assist, trailer sway control, tyre-pressure monitoring, SOS post-crash alert system and lots more.
The GMC Yukon Denali does not have an ANCAP safety rating because it has not been tested.
Standard safety features include six airbags (including full-length curtain airbags for all three rows) and a full suite of driver-assist tech includes AEB (with pedestrian detection), adaptive cruise control, blind-spot monitoring, lane-keep assist, rear cross-traffic alert, front and rear parking sensors, tyre-pressure monitoring, a surround-view camera, trailer sway control, trailer hitch guidance with hitch view and more.
Harrison F Trucks provides a four-year/130,000km warranty, which it claims is the same as the Ford warranty with standard exclusions. Harrison also provides four-year premium roadside assistance.
Scheduled servicing is 12 months/10,000km with costs ranging between $495 and $1400.
Harrison says servicing can be done at any certified service department in Australia, with direct communication with Harrison’s service manager if required for diagnostics and advice.
The 2025 GMC Yukon Denali has a three-year/100,000km warranty – which is on the wrong side of ordinary in this day and age.
Roadside assistance is available for three years but check with your dealership for more details on that.
Servicing is scheduled for every 12 months or 12,000km. The first three workshop visits come in at $398.33, $420.33 and $506.48, including GST. Not outrageous for such a hefty beast.
