GMC Yukon

2026 GMC YUKON DENALI ULTIMATE 4WD — CANADIAN SPECIFICATION

ENGINE AND DRIVETRAIN

GMC Canada fits the 6.2-litre EcoTec3 V8, engine code L87, as standard equipment on the Denali Ultimate, rated at 420 horsepower at 5,600 rpm and 460 lb-ft (624 Nm) of torque at 4,100 rpm. It is a naturally aspirated aluminium-block design with direct injection, variable valve timing and Dynamic Fuel Management cylinder deactivation, certified to run on E15 fuel. Drive passes through a 10-speed automatic transmission — electronically controlled with overdrive, operated by a steering-column-mounted electronic gear selector and including the Traction Select System with tow/haul — to a four-wheel-drive system built around the Autotrac two-speed transfer case and an electronic limited-slip differential. Final drive is 3.23:1. Automatic Stop/Start is fitted with a per-cycle disable button. The 3.0-litre Duramax turbo-diesel is the alternative powertrain offered on this grade in Canada and is not fitted to this vehicle.

CHASSIS, STEERING AND BRAKES

Suspension is independent at both ends: front coil-over-shock with a stabilizer bar, rear multi-link with coil springs. Denali Ultimate and AT4 Ultimate are the only Canadian Yukon grades to receive both Magnetic Ride Control and the four-corner Air Ride Adaptive Suspension as standard. The air system varies ride height and spring rate, raising the body one or two inches for ground clearance at low speed on four-wheel-drive models and lowering it two inches for entry, exit and cargo loading. The Active Response 4WD System coordinates the Autotrac transfer case, Traction Select drive-mode control, StabiliTrak and the electronic limited-slip differential. Steering is power-assisted; braking is by four-wheel anti-lock disc brakes. Wheels are 24-inch selective machined and painted After Midnight Metallic aluminium on all-season blackwall tyres with bright wheel locks. A 17-inch full-size steel spare on a P265/70R17 all-season tyre is carried on a lockable winch-type carrier under the frame at the rear.

DIMENSIONS AND CAPACITIES

GMC Canada publishes a gross vehicle weight rating of 7,600 lb (3,492 kg) and a maximum payload of 2,120 lb (961 kg) for this configuration. GMC Canada does not publish exterior dimensions — overall length, width, height or wheelbase — for the Yukon on its Canadian consumer or configurator material, so no Canadian figure is stated here, and the corresponding US-sheet numbers were deliberately not substituted: the two markets do not always publish identical dimension sets and a wrong figure would corrupt freight cubing. Kerb weight is likewise not published by GMC Canada for this grade and is not stated. The interior and capacity figures carried on the selling listing come from the marketplace's own US-based trim database rather than a Canadian sheet, and are reproduced on that basis: 1,130 mm of front legroom, 1,067 mm of rear legroom, 722 litres of cargo volume behind the third row, and a 91-litre fuel tank.

EXTERIOR

The body is finished in Black, with painted mirror caps and chrome door handles carrying a body-colour strip. Denali Ultimate adds Vader bodyside mouldings over the lower grades. Lighting is LED throughout — animated LED headlamps, animated LED tail lamps and LED fog lamps. A panoramic power sunroof spanning the first and second rows is standard on this grade, opening and tilting at the push of a button, as are power-retractable assist steps with LED perimeter lighting and the AutoSense power liftgate. Glazing comprises an acoustic laminated windshield with shade band, laminated driver and front-passenger door windows and deep-tinted rear side and liftgate glass. Bright roof-mounted side rails, upper active aero shutters, Rainsense automatic wipers, a rear intermittent wiper and a rear camera washer are fitted, along with a dual-outlet exhaust ending in dual rectangular twin polished stainless-steel tips. The outside mirrors are body-colour, heated and power-adjusting with integrated turn signal indicators, and auto-dimming on the driver's side; GMC Canada does not list power-folding mirrors on this grade, so none is claimed.

INTERIOR AND SEATING

The cabin is trimmed in full-grain leather, with the interior colour recorded by the seller as Brown. Seating is a seven-passenger three-row arrangement: front buckets, power-release second-row bucket seats and a power 60/40 split-folding third-row bench that operates from the overhead console or the cargo area and folds each side flat independently. The front seats are heated, ventilated and massaging on both sides, with 8-way power adjusters, 4-way power lumbar, and 2-way power upper shoulder and back bolster adjustment, plus driver memory settings. The second-row outboard seats are heated. A Safety Alert Seat provides haptic driver warnings. The steering wheel is leather-wrapped and heated on a power tilt-and- telescoping column with mounted controls. A power-sliding centre console, bright sill plates, a sport pedal cover kit, removable colour-keyed carpeted mats for the first two rows and illuminated visor mirrors complete the fit-out. Climate control is tri-zone automatic with a separate 8-inch rear touchscreen, rear air conditioning, a cabin air filter and a rear window defogger. The second-row heated and ventilated executive seating with massage and Bose head-restraint speakers is a separate Canadian option on this grade and is not confirmed on this vehicle; neither is Night Vision, the other principal Denali Ultimate option.

INFOTAINMENT AND CONNECTIVITY

The centre display is a 16.8-inch diagonal advanced colour LCD with Google built-in compatibility, supported by an 11-inch colour Driver Information Centre and a 15-inch diagonal multicolour Head-Up Display, the last of which the selling dealer separately confirms on this unit. Audio is the Bose Performance Series CenterPoint Surround 18-speaker system. Wireless Apple CarPlay and wireless Android Auto are supported, alongside a Rear Seat Media System, SiriusXM with a 360L trial subscription, wireless phone charging, OnStar services with a three-year OnStar One plan, and 5G Wi-Fi hotspot capability. USB provision is two type-A and type-C charge-and-data ports on the front console and two charge-only type-C ports in the third row; GMC Canada lists no second-row USB outlet on this grade. Two 120-volt outlets are fitted, in the rear of the centre console and in the cargo area. Universal Home Remote, Keyless Open, Keyless Start and Remote Start are standard. An interior camera is installed but requires a future software update before it functions.

DRIVER ASSISTANCE AND SAFETY

Super Cruise hands-free driver assistance is standard on the Canadian Denali Ultimate with a three-year OnStar One plan, and operates only on compatible mapped roads. Adaptive Cruise Control is standard. The standard assistance set also covers Enhanced Automatic Emergency Braking, Intersection Automatic Emergency Braking, Front Pedestrian and Bicyclist Braking, Forward Collision Alert, Reverse Automatic Braking, Rear Cross Traffic Braking, Rear Pedestrian Alert, Side Bicyclist Alert, Blind Zone Steering Assist with Trailering, Driver Attention Assist, Traffic Sign Recognition, IntelliBeam automatic high beams, HD Surround Vision, a Rear Camera Mirror, Enhanced Automatic Parking Assist, Hill Descent Control, Hill Start Assist, and StabiliTrak electronic stability control with traction control and trailer sway control. The selling dealer additionally lists Lane Assist on this vehicle; GMC Canada does not itemise a lane-keeping or lane-departure system in Denali Ultimate standard equipment, so its exact form is not confirmed here. Passive protection is seven airbags: frontal airbags for driver and front passenger, a driver inboard seat-mounted side-impact airbag, seat-mounted side-impact airbags for driver and front passenger, and head-curtain airbags for the front and rear outboard seating positions. GMC Canada lists no knee airbag on this vehicle. Also fitted are a front outboard Passenger Sensing System, Rear Seat Reminder, Buckle to Drive, Teen Driver, the LATCH child restraint system, rear child security door locks, a tyre pressure monitoring system, and electrical and content theft-deterrent systems with the Advanced Security Package's inclination, interior movement and glass-breakage sensors. Neither GMC Canada nor the selling listing publishes an NHTSA, IIHS or NCAP crash rating for this vehicle.

TOWING AND CAPABILITY

Configured as here — Denali Ultimate 4WD with the 6.2-litre V8 — GMC Canada quotes a maximum trailering rating of 8,000 lb (3,629 kg). The 8,400 lb figure that appears in GM Canada's Yukon press material is a lineup maximum for a different configuration and does not apply to this vehicle. The Max Trailering Package is standard on this grade, as are trailering equipment, a trailering hitch platform with a 2-inch receiver, an integrated trailer brake controller, an external auxiliary transmission oil cooler, an external engine oil cooler and an enhanced cooling radiator. Trailer-specific assistance covers Hitch Guidance, Hitch View, a Smart Trailer Integration Indicator and trailer sway control. Electrical capacity is a heavy-duty 730 cold-cranking-amp battery with rundown protection and retained accessory power, and a 220-amp alternator. Fuel consumption published on the selling listing is 16.8 L/100 km city and 13.1 L/100 km highway; the marketplace states these are EPA-derived estimates, so they are not NRCan Canadian ratings, and no verified CO2 figure exists for this vehicle.
