Gmc Yukon vs Jeep Gladiator

What's the difference?

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. 

The Jeep Gladiator Rubicon is a very capable off-roader and it's not as terrible on-road as some people might assume.

But while it's a whole lot of fun to steer around on the dirt, it lacks the versatility, safety tech, and refinement that would shift it from simply being a decent hard-core 4WD ute to a good general-purpose vehicle.

However, by focussing on those factors, you're in danger of missing the Gladiator's point entirely. This is a purpose-built 4WD fun machine, which is perfect for its intended use. But, the problem is, it's not perfect, or even very good, at anything else.

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.

The Jeep Gladiator appears built for purpose if your purpose is to head bush and have fun. And in Rubicon form it sure looks like it's capable of tackling hard-core 4WDing.

The Gladiator looks very much like its stablemate, the iconic Wrangler, with its chunky front end and blocky body.

It has more than the inkling of a US-style pick-up's presence at 5591mm long (with a 3488mm-long wheelbase), 1894mm wide, 1909mm high, and with a kerb weight of 2242kg.

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”.

You have to give Jeep's designers credit because they know their outdoorsy stuff. The Gladiator's interior is nothing if not practical.

The ute has a squared-off and action-ready interior that seems up to the task of copping the dirt of an outdoors life.

The cabin feels like it's water- and weather-proof, even if that may not literally be the case. 

It's a snug interior and build quality generally feels solid.

The 8.4-inch multimedia touch screen is clear and easy enough to read while on the go, but it's too small. The Jeep's 'Uconnect' system is simple enough to get your head around and Apple CarPlay and Android Auto are easy to get working.

There's also a 7.0-inch LED driver-information display, which shows tyre pressure, tyre-fill alert, digital speed readout and more.

All controls, dials and switchgear are chunky, making for easy operation, no matter how bumpy the terrain you're traversing is.

The reach-and-rake-adjustable steering wheel incorporates audio, voice and cruise control controls.

Storage spaces are few, but at least they're well suited to adventure, such as tensioned mesh pockets on the doors and seat backs and small spaces with textured bases for your bits and pieces.

There are two USB-A ports and a USB-C port up front and two for back-seat passengers. There's also a 230V outlet up front on the centre console.

Seating is decent all-around but anyone taller than Tom Cruise's stunt double has to mind their head so they don't thump it on the unforgivingly hard ceiling of the detachable top.

There's a shallow storage space under the rear seat and, when that 60/40 split rear seat is folded flat, there are LED lights behind to illuminate the narrow storage space in the rear of the cabin, where there are also storage nets.

The tub's load space is 1442mm wide – 1137mm between the wheel arches so not wide enough for a pallet – and it is 1531mm long. Load height is 885mm at the tailgate.

The tray has integrated tie-down points and under-rail LED lights.

Payload is now a claimed 693kg, which is better than its previous 680kg but still rather ordinary when compared to a lot of dual-cab utes available in Australia.

Gross vehicle mass and gross combined mass are listed as 2935kg and 5656kg, respectively.

The Gladiator has a maximum towing capacity of 750kg (unbraked), and its 2721kg braked towing figure is a let-down against the 3500kg capacity of most other rivals.

This is a ute better suited to weekend camping trips than load-lugging work duties.

Another bonus for tourers though: the spare wheel is a full-size steel one.

The 2023 Jeep Gladiator Rubicon has an official list price of $87,250, excluding on-road costs.

This variant's more notable standard features include Jeep's 'Rock-Trac Active On-Demand II' 4x4 system (4:1 transfer case), 'Tru-Lok' front and rear locking differentials, sway-bar disconnect, Tenneco 2.0-inch diameter aluminium-bodied shocks (front and rear; Fox shocks on previous versions), a 'TrailCam' off-road camera, selectable tyre-fill alert, BFGoodrich Mud Terrain tyres (255/75 R17), and 17-inch machined-black alloy wheels.

It also has an 8.4-inch touchscreen multimedia system (with navigation, Apple CarPlay and Android Auto), as well as LED headlights/tail-lights/daytime running lights/fog lights, forward collision warning, plus adaptive cruise control, blind-spot monitor with rear cross-path detection, remote proximity keyless entry and a nine-speaker Alpine Premium audio system.

Gladiator paint choices include standard black and 'Bright White', as well as $895 premium paint options including 'Sarge Green', 'Silver Zynith', 'Firecracker Red', 'Sting Grey', 'Hydro Blue', 'Granite Crystal' and 'High Velocity' (yellow/green).

The accessories range for the Gladiator is a line-up of more than 70 bits of gear, and includes everything from Jeep windscreen sunshades to a cargo bed storage system (drawers).

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.

The Gladiator Rubicon has the Wrangler's 3.6-litre Pentastar V6 petrol engine (209kW at 6400rpm and 347Nm at 4100rpm) and eight-speed automatic transmission.

The V6 has a lot of punch for on- and off-road driving and plenty of low-end torque for low-range 4WDing and, matched with the eight-speed auto, it's a well-proven team-up that consistently works well.

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. 

The Gladiator Rubicon has listed fuel consumption of 12.4L/100km on a combined cycle. 

On test I recorded actual fuel consumption of 12.9L/100km, from fill to fill.

The Gladiator has an 83-litre tank, so, going by my on-test fuel-use figure, you could reasonably expect a driving range of approximately 643km from a full tank.

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.

It's certainly an experience, but the Gladiator is not as atrocious on-road as you may assume.

This vehicle is a lot of fun to drive because it demands a lot of attention and input to keep it on target.

The steering is floaty, with plenty of play in the wheel and understeer through corners, and there's a fair bit of tyre rumble from the BFG muddies.

The wing mirrors generate noticeable wind noise, but the Gladiator's not as awkward or unrefined as you might expect.

Because it's essentially a stretched Wrangler – with a 787mm longer body and a 480mm longer wheelbase than its stablemate – the Gladiator has a solid stance on the road and, for such an unashamedly off-road-oriented vehicle, it feels even more settled and composed than the Wrangler does on sealed surfaces.

This 2242kg ute is built for tough fun with a body-on-frame design and reinforced chassis, but the Gladiator manages to be nimble around town.

Ride quality is generally impressive with this ute cruising comfortably on live axles front and rear with coil springs and, in 2023 onward versions, Tenneco shocks all-around rather than the previous Fox Shocks set-up.

Aspects of the Gladiator experience will annoy some people. Visibility is compromised in all directions, the throttle is touchy, the 13.6m turning circle may add a degree of difficulty in attempts at fast turnarounds (on a city street or in a busy country pub car park) and all that driver attention and input the Gladiator demands of its steerer will become tiresome for a few drivers.

But, as expected, the Gladiator's true spirit is only ever fully revealed when you head off-road. It's a hell of a lot of fun in the dirt. Drop tyre pressures, do up your seat belt and let the Gladiator off the leash.

The 'Trail Rated' Gladiator is loaded with off-road mechanicals, from a 4X4 system with 4:1 low-range (contributing to a 77.2:1 crawl ratio), front and rear diff-locks, heavy-duty Dana 44 axles (front and rear), sway-bar disconnect and BFGoodrich Mud Terrain tyres, as well as a stack of driver-assist tech aimed at making you feel like Australian 4WD expedition legend Ron Moon.

Shocks engineered for off-roading add a welcome dimension of comfort and handling to the Gladiator on fast dirt and gravel tracks on the way to your chosen off-roading destination.

That 77.2:1 crawl ratio means nothing to most of us until you have the opportunity to experience the feeling of all that terrain-gripping torque for yourself.

In 4WD low-range first gear, and with both diffs locked, the Gladiator feels unstoppable. It climbed with ease a short steep rocky hill where I've seen drivers of modified vehicles opt for the ‘chicken' tracks either side.

The only thing is, because of the Gladiator's 3488mm-long wheelbase and 18.4-degree ramp-over angle, there's a real risk of bellying out or at least grinding the undercarriage on earth when you crest these steep hills, which is why you must drive with concentrated focus.

But that's part of the fun. It really is a driver-direct experience. You need to be aware of everything that's going on, you never feel like you're one step removed from the situation, or the terrain or the consequences of your driving… you feel dialled into the terrain and that's guaranteed to put a smile on any 4WD enthusiast's face.

Besides, the Gladiator does have substantial underbody skid-plates, protecting the fuel tank, transmission and transfer case, as well as heavy-gauge tubular steel rock rails to soak up off-road hits.

With an approach angle of 40.7 degrees, a departure angle of 25.1 degrees and a listed ground clearance of 249mm and a wading depth of 760mm, the Gladiator has decent off-road measures.

Suspension travel is okay, but to get even more stretch, you can hit the sway-bar disconnect button to drop a wheel to the dirt – or as close as possible depending on how deep the ruts are.
 
The Gladiator has 'Selec-Speed Control' (effectively an adjustable low-speed cruise control for 4WDing that can be set between 1.0-8.0km/h), and 'Off-Road+', which tweaks throttle and traction control, among other systems, to best suit the terrain.

It also has a forward-facing off-road camera so the driver has a chance to see any obstacles that might otherwise go unnoticed until it's too late, such as branches, rocks, tree stumps and hard rubbish.

The Gladiator has a three-star ANCAP safety rating from testing in 2019.

Its safety gear includes four airbags, full-speed forward collision warning plus, reversing camera, adaptive cruise control, blind-spot monitoring, rear cross-path detection, tyre-pressure monitoring system, and more.

It also has hill start assist, hill descent control, and trailer sway control.

It has dual ISOFIX child seat anchor points and three top-tether attachments in the rear seat.

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.

The Gladiator has Jeep's five-year/100,000km factory warranty, five-year capped price scheduled servicing, and lifetime roadside assistance.

The first five services are capped at $399 each and scheduled servicing is due every 12 months or 12,000 km, whichever comes first.
