Gmc Yukon vs Lexus RX

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 new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

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 RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

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”.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

There are four variants in the RX range, and we’re testing the 450h+ Sports Luxury AWD, which sits just below the flagship and packs in plenty of premium kit for its $123,500, before on-road costs, price tag.

That makes it slightly more affordable than its main PHEV rivals; the BMW X5 xDrive50e (from $125,885 MSRP) and the Volvo XC90 Ultra (from $124,466 MSRP).

The Volvo does offer seven seats to the Lexus’ five, which may matter for larger families, and both rivals also outdo the RX on electric-only driving range - 65km in the RX compared with 77km in the Volvo XC90 and a generous 101km in the BMW X5.

Still, the RX fights back with a seriously stacked features list. Highlights include a panoramic sunroof, 10-way powered front seats with heating and ventilation, electrically folding rear seats (also heated and ventilated in the outboard positions), and a heated, power-adjustable steering wheel. Sound is taken care of by a premium 21-speaker Mark Levinson surround system.

Technology has had a solid upgrade with the 14-inch touchscreen multimedia display, 12.3-inch digital instrument cluster, digital rearview mirror, colour head-up display, live traffic navigation, wireless Apple CarPlay and Android Auto, 4G connectivity, four USB-C ports, one USB-A port and a fast wireless charging pad.

There’s also access to the 'Lexus Connected Services' app, allowing you to remotely lock or unlock the vehicle, pre-set the cabin temperature via three-zone climate control, configure driver profiles and even use your phone as a digital key.

Practical features include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, rear sun-blinds, intelligent seatbelt reminders for the first two rows, a child presence alert and a hands-free powered tailgate. However, due to the plug-in hybrid system there’s no spare tyre, just a tyre repair kit.

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.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

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 plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

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.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

The RX earned a maximum five-star ANCAP safety rating in 2022, scoring highly across all protection categories: 90 per cent for adult protection, 89 per cent for child protection, 89 per cent for vulnerable road users, and 93 per cent for safety assist systems.

Standard safety gear includes eight airbags (dual front, front side, curtains, front centre, and driver’s knee) plus a comprehensive suite of driver aids. Standout features include emergency call functionality, child detection alert, side exit assist, front and rear collision warnings, park assist and emergency steering assist.

Additional tech covers blind-spot monitoring, driver attention monitoring, tyre pressure monitoring, daytime running lights, LED cornering lights, rear cross-traffic alert, lane departure alert, lane keeping assist, traffic sign recognition, and intelligent seatbelt warnings for the front two rows.

Visibility and parking are enhanced by a 360-degree camera system and front/rear parking sensors, while adaptive cruise control adds comfort on longer drives.

The rear seats have two ISOFIX mounts plus three top tether anchors, accommodating child seats safely. Autonomous emergency braking is active from 5.0 to 80km/h for pedestrians, cyclists, and backover and up to 180 km/h for cars.

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 RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.
