General Motors Specialty Vehicles has added a second version of the Yukon Denali, the only GMC model on its Australian site. The Yukon Denali Signature Black is, in GMSV's own words, "a locally specified expression of full-size GMC luxury": a black-on-black Yukon Denali with 24-inch black wheels and, more usefully, second-row captain's chairs that turn the eight-seat Denali into a seven-seater. Motoring outlets report it at $181,490 before on-road costs, which they put at $6,500 over the regular Denali, and describe it as available to order now.

We have not been able to confirm the price on a GM page. GMSV's Australian Yukon Denali page describes the Signature Black in detail but prints no price for either version, so the $181,490 figure stays "reported" in this story. Everything else below comes from GMSV's Australian site and GM's own specification guide, and where the guide only covers the eight-seat Denali, we say so.

The short version: the Signature Black is a cosmetic and seating change, not a mechanical one. It is the same V8, the same gearbox and the same air suspension, so the questions worth asking are the ones that apply to every Yukon, and the most important of those is what the towing figure actually means.

Pricing

GM prices the Yukon as a recommended retail price, before on-road costs. The Signature Black row is the figure Australian outlets report; the Denali row is the figure GM Australia and New Zealand published when the Yukon launched here in May 2025.

When GM launched the Denali, it said the $174,990 price included GST and luxury car tax but excluded dealer delivery, government charges, on-road costs and optional extras. The outlets reporting the Signature Black price quote it the same way, before on-road costs, and report the regular Denali still at $174,990. On the road you will pay more than either figure once registration, stamp duty and dealer delivery are added, and those vary by state.

One more thing worth knowing if you are pricing a Yukon this month. GMSV's terms for its "3 Years Free Scheduled Servicing" offer covered new Silverado 1500 and Yukon Denali vehicles delivered between 1 August 2026 and 5pm on 30 September 2026, unless extended or withdrawn earlier. That window has now closed on its published terms, so ask the dealer whether it has been extended before you assume it applies.

What the Signature Black Changes

GMSV lists the changes on its Yukon Denali page. On the outside, it is finished in Onyx Black, with what GM calls Black Vader Chrome on the grille, grille surround, front fascia accent trim, side mouldings and lower rear fascia accent trim. The exterior badging is black, the hood moulding and roof luggage rails are gloss black, and GMSV notes an illuminated GMC emblem is included on the Australian specification. The wheels are 24-inch black accessory wheels in place of the regular Denali's machined and painted Pearl Nickel 24s.

Inside, the change that matters is the seating. The regular Denali is an eight-seater with a second-row bench; the Signature Black has two captain's chairs in the middle row, which makes it a seven-seater and opens a walkway through to the third row. GMSV lists Jet Black perforated leather, heated front and rear seats, ventilated front seats, tri-zone automatic climate control and a power-sliding centre console.

Most of that list is already standard Denali equipment. GM's own Denali equipment list includes Jet Black perforated leather, heated and ventilated front seats, heated rear seats, tri-zone climate control, a 16.8-inch central touchscreen, dual 12.6-inch rear-seat screens and a 14-speaker Bose system. So, on what GMSV has published, the reported $6,500 buys the black exterior treatment, the black wheels, the illuminated emblem and the captain's chairs, plus the power-sliding centre console, which GM's MY25 Denali equipment list does not include. GMSV has not said whether the edition is limited in number.

What Stays the Same

*These three come from GMSV's MY25 Yukon Denali features and specifications guide, which covers the eight-seat Denali and is dated March 2025. GMSV has not published a separate guide for the Signature Black, and the different seats and wheels could move its weights, so treat the guide's figures as the Denali's rather than as confirmed for this edition.

Those dimensions matter more than they might look. At 5,337mm long and 2,058mm wide before the mirrors, this is a big vehicle for Australian car parks and home garages; GM's guide gives 2,378mm across the mirrors. A 12.4-metre turning circle is not unreasonable for something this long, but measure your garage before you get attached to it.

The Towing Figure Needs Reading Carefully

GMSV headlines the Yukon Denali with 3,628kg maximum braked towing, and qualifies it on its own page as an "available" maximum. GM's specification guide for the eight-seat Denali spells out what that means, and it is the most useful thing in the document for anyone buying a Yukon to tow.

So the headline number is a set-up number. On a conventional hitch, GM's guide gives the Yukon 2,720kg, which is well short of the 3,500kg we list for the LX600, the LandCruiser 300 and the Patrol Warrior. To reach 3,500kg you need a weight distribution hitch, and to reach 3,628kg you need that hitch with a 70mm ball. The guide notes the tow ball and hitch kits are accessories sold separately, and GM's launch material says the Yukon comes with a towbar, a 12-pin harness and an integrated trailer brake controller.

Then there is the mass arithmetic, which is ours, done on GM's published eight-seat figures. GVM minus kerb weight leaves about 634kg for people, luggage, accessories and towball download. And the GCM of 6,577kg minus a 3,628kg trailer leaves about 2,949kg for the Yukon itself, only around 136kg above its kerb weight. In plain terms: if you hook up a trailer at the full 3,628kg, the combination limit leaves very little room for a family and their gear in the car. That is not unusual for a big wagon, but it means the 3,628kg figure is something to plan around rather than to load up to.

If you are thinking of a Yukon for a caravan, run your actual van, passengers and gear through our TowingSorted planner or the towing and payload calculator, which do the GVM, GCM and ball-weight checks properly. Use GM's numbers from the table above, and ask GMSV for the Signature Black's own compliance plate figures before you commit, because captain's chairs and different wheels can shift the tare.

For context against the big SUVs we list: among the SUVs on sale in our database, none has a braked towing figure above 3,500kg. The only on-sale rows we hold that go higher are utes and light trucks. GM called the Yukon's figure best in class for an SUV when it launched in 2025, but that claim predates the new-generation Nissan Patrol Y63. Nissan Australia quotes 3,700kg braked towing for every Y63 grade, which is more than the Yukon's 3,628kg, and we list it as coming soon rather than on sale.

Against the Big SUVs We List

GM pitches the Yukon as a vehicle without a direct equivalent here, and on the full-size American formula that is fair. But a buyer spending this kind of money will almost certainly look at the Lexus LX600 Sports Luxury, which we list at $179,800 before on-roads, or the LX600 Luxury at $167,700. On our figures the LX600 is a seven-seater with a 305kW, 650Nm petrol engine, a 3,500kg braked towing figure and a claimed 11.9L/100km. So at the reported price the Signature Black costs about $1,700 more than the LX600 Sports Luxury, has 8kW more and 26Nm less, uses a little more fuel on paper, and asks for a weight distribution hitch to beat the Lexus on towing.

The Toyota LandCruiser 300 Sahara ZX is the value yardstick. We list it at $146,910 before on-roads, from Toyota Australia's published pricing, and on our figures it is a five-seater with a 227kW, 700Nm diesel, 3,500kg towing and 8.9L/100km. It gives up two seats and a lot of cabin, but it is more than $34,000 cheaper than the reported Signature Black price and uses a good deal less fuel on paper.

We also list the Nissan Patrol Warrior, an eight-seat petrol V8; the BMW X7 xDrive40d, a seven-seat diesel; and the Land Rover Defender 130 V8 P500, a seven-seat petrol V8 we list with 3,000kg towing. We have not quoted prices for those three because we have not yet checked them against the manufacturers; the comparison below shows the figures we currently list.

And in the same GMSV showroom, the Chevrolet Silverado 1500 LTZ Premium uses the same 313kW, 624Nm 6.2-litre V8 on our figures. If what you really need is to tow heavy and the third row is a nice-to-have, the pickup is the more honest tool for that job; if the family comes first, the Yukon is the one built around them.

Safety, Tax and the Fine Print

ANCAP. We hold no ANCAP rating for the Yukon Denali and could not find one on ANCAP's site, so its rating is no data as far as we are concerned. GMSV lists 15-plus standard safety and driver assistance features, including automatic emergency braking, forward collision alert and rear cross traffic alert, and GM's May 2025 launch release lists six airbags. If your employer or fleet policy requires a rating, that is a gap to raise before you order.

Luxury car tax and FBT. As general information for the 2026-27 financial year: at a claimed 12.8L/100km the Yukon is well above the 3.5L/100km fuel-efficient line, so the standard $80,809 luxury car tax threshold is the one that applies, and GM said its Denali list price already includes LCT. It is not an electric car, so there is no FBT exemption on a novated lease. Talk to your accountant or lease provider about your own position.

Warranty and servicing. GMSV's Australian warranty page lists a bumper-to-bumper warranty of 3 years or 100,000km, whichever comes first, from first registration. That is worth weighing on a vehicle of this price, and worth comparing against the warranty on whatever else you are looking at. GM's guide lists service intervals of 12 months or 12,000km.

Right-hand drive. GM's 2025 launch release says the Yukon is re-engineered to right-hand drive by GMSV's re-manufacturing partner at its facility in Dandenong, Victoria, the same team that converts the Silverado. GM does not name the partner there; outlets report it is the Walkinshaw Group, so we are reporting that rather than confirming it.

What GMSV Has Not Published

• The Signature Black price on a GM page. $181,490 is what outlets report.
• Signature Black weights and towing. The only mass and towing figures are for the MY25 eight-seat Denali.
• A fuel figure for the Signature Black, or whether the black accessory wheels change the tyre specification. The Denali guide lists 285/40R24 tyres.
• Whether it is a limited run, and how many are coming.
• Delivery timing. Outlets report it is available to order now; GMSV's page gives no date.
• An ANCAP rating for any Yukon.

Who It Suits, and Who It Does Not

It suits the buyer who was already set on a Yukon Denali and has older kids or adults in the middle row. Captain's chairs make getting into the third row far easier, and for a family of five to seven that is a real everyday improvement, not just a look. If you like the blacked-out styling as well, the reported $6,500 is the price of both.

It suits less well a family that regularly needs all eight seats, because the Signature Black has seven, and anyone who wants to tow a heavy van without adding a weight distribution hitch, because the conventional-hitch figure in GM's guide is 2,720kg. It is also a hard sell on running costs against a diesel LandCruiser, and the 3-year warranty is short at this price. If you want a petrol V8, three rows and the American full-size experience, the Yukon delivers exactly that; if you mainly want a big, capable seven-seater, the LX600 and LandCruiser are worth pricing first.

We do not list the GMC Yukon in the CarSorted directory yet, and we will add it with GM's published figures. Current offers from other brands are on our deals page.
