2026 GMC YUKON DENALI ULTIMATE 4WD — CANADIAN SPECIFICATION

ENGINE AND DRIVETRAIN

The Denali Ultimate is powered by GM's L87 6.2-litre naturally aspirated V8, the standard and fitted engine on this grade in Canada. It produces 420 hp at 5,600 rpm and 460 lb-ft (624 Nm) at 4,100 rpm from an aluminium block with direct injection, variable valve timing and Dynamic Fuel Management cylinder deactivation. Drive passes through a 10-speed automatic transmission, electronically controlled with overdrive, a Traction Select system with tow/haul mode and a column-mounted Electronic Precision Shift selector. Automatic Stop/Start is standard and carries a disable button that resets on each engine cycle. Four-wheel drive is standard and is delivered by the Premium Capability Package with Active Response 4WD, which integrates an Autotrac two-speed transfer case, Traction Select drive mode control, brake-based StabiliTrak intervention and an electronic limited-slip differential. The rear axle ratio is 3.23. Supporting hardware includes an external auxiliary transmission oil cooler, an external engine oil cooler, an enhanced-cooling radiator, a 220-amp alternator, a 730 cold-cranking-amp heavy-duty battery and a dual-outlet exhaust with twin polished stainless-steel tips. The engine is certified for E15 gasoline. Fuel tank capacity is 91 litres. The EnerGuide ratings GMC Canada publishes for this configuration are 16.6 L/100 km city and 13.0 L/100 km highway; no combined figure and no Canadian tailpipe CO2 rating appear on that sheet, so neither is stated here.

CHASSIS, STEERING AND BRAKES

Suspension is independent front coil-over-shock and rear multi-link, fitted on this grade with the Air Ride Adaptive Suspension: a four-corner air system whose variable-rate springs replace conventional coil springs, giving automatic load levelling and selectable ride height. It raises the body 25 mm (1 in) or 51 mm (2 in) at low speed for improved ground clearance and lowers it 51 mm (2 in) for entry, exit and cargo loading. Magnetic Ride Control is standard and reads each wheel independently, adjusting damping every millisecond by altering the magnetorheological damper fluid rather than by moving valves. Steering is power assisted. Braking is by four-wheel antilock discs on Duralife rotors, supported by StabiliTrak electronic stability control with traction control and Brake Assist, Hill Start Assist and Hill Descent Control. The six-piston Brembo front brake upgrade is an available option on this grade and is not fitted to this unit. Wheels are 24-inch selective machined and painted After Midnight Metallic on 285/40R24 all-season blackwall tyres, secured with bright wheel locks. A 17-inch full-size steel spare on a P265/70R17 all-season tyre rides on a lockable winch-type under-frame carrier, with a mechanical jack and tools.

DIMENSIONS AND CAPACITIES

Every figure in this section is taken from GMC Canada's own configurator specification sheet for the 2026 Yukon Denali Ultimate 4WD; United States sheets differ and are not used. Overall length is 5,337 mm (210.1 in), overall height 1,943 mm (76.5 in) and maximum width excluding mirrors 2,057 mm (81.0 in), on a 3,073 mm (121.0 in) wheelbase. Curb weight is 2,531 kg (5,580 lb), distributed 1,302 kg front and 1,229 kg rear. Gross vehicle weight rating is 3,493 kg (7,700 lb) and maximum payload 962 kg (2,120 lb). Gross axle weight ratings are 1,678 kg front and 1,950 kg rear, leaving 376 kg and 562 kg of reserve axle capacity respectively. Cargo volume is 722 litres behind the third row, 2,053 litres behind the second row and 3,477 litres behind the first row, across a cargo box 1,257 mm wide between the wheelhousings. Passenger capacity is seven. Front head, leg, shoulder and hip room measure 1,026 mm, 1,130 mm, 1,664 mm and 1,562 mm; the second row 952 mm, 1,067 mm, 1,643 mm and 1,557 mm; the third row 970 mm, 886 mm, 1,593 mm and 1,255 mm. GMC Canada lists front and rear ground clearance as to be determined on this sheet, so no ground clearance figure is stated.

EXTERIOR

Lighting is LED throughout: headlamps and tail lamps with animated lighting sequences, plus LED fog lamps, with IntelliBeam automatic high-beam control operating above 40 km/h. Glazing comprises an acoustic laminated windshield with a shade band, laminated driver and front passenger door glass, and deep-tinted rear side and liftgate glass. A dual-panel panoramic power sunroof opens over the first and second rows, tilts for ventilation and carries a power sunshade. The AutoSense power liftgate opens on key-fob proximity and its opening height is programmable from the overhead console. Power-retractable assist steps run wheel well to wheel well with LED perimeter lighting and textured step pads. Mirrors are body-colour, heated and power-folding with driver-side auto-dimming, under body-colour caps on this grade. Further exterior fittings are bright roof-mounted side rails, chrome door handles with a body-colour strip, Vader bodyside mouldings, a rear camera washer, a variable-speed rear intermittent wiper, Rainsense automatic front wipers and upper active aero shutters that close at speed to reduce drag. The seller publishes no exterior paint name for this unit, so none is stated.

INTERIOR AND SEATING

Seating is a seven-passenger 2+2+3 layout trimmed in full-grain leather, with front buckets, second-row buckets and a third-row bench. The front seats are heated and ventilated and carry sixteen powered adjustments each: an 8-way adjuster, 4-way power lumbar, 2-way power upper shoulder and 2-way power bolster, with a power massage function for both driver and front passenger. Two driver memory presets recall seat and mirror positions. The second-row outboard seats are heated and power-release at the press of a button to fold and tumble; the third row is a power 60/40 split-folding bench whose halves fold flat independently. The centre console slides rearward up to 254 mm (10 in) on an overhead power switch. The steering wheel is a heated, leather-wrapped four-spoke unit with mounted controls on a power tilt and telescoping column. Climate control is tri-zone automatic with rear air conditioning and an 8-inch rear touchscreen climate panel on the back of the console that also carries second-row heated-seat controls. Also standard are colour-keyed carpeting with first and second row mats, a cabin air filter, bright sill plates, a sport pedal cover kit, illuminated visor mirrors, front and second-row assist handles, delayed-entry interior lighting, power windows with front express-up/down and rear express-down, programmable power door locks, rear child security locks, a rear window defogger, Keyless Open with Keyless Start and a key card, remote start and Universal Home Remote. The Executive Second Row Seating Package, Night Vision, the Performance Upgrade Package, the alternative 22-inch and 24-inch wheel choices and the Enhanced Trailering Technology Package are all available on this grade but are not listed by the seller and are treated as not fitted.

INFOTAINMENT AND CONNECTIVITY

The centre display is a 16.8-inch diagonal advanced colour LCD with Google built-in compatibility and native navigation, paired with an 11-inch diagonal colour Driver Information Centre and a 15-inch diagonal multicolour head-up display projected onto the windshield. Audio is the Bose Performance Series CenterPoint Surround system with eighteen speakers. Wireless Apple CarPlay and wireless Android Auto are supported for compatible phones, alongside wireless phone charging, two front-console USB ports in type-A and type-C carrying both charge and data, two charge-only type-C ports for the third row and two 120-volt outlets at the rear of the centre console and in the cargo area. A Rear Seat Media System mounts dual 12.6-inch colour touch LCD screens to the front seatbacks. Connectivity runs through OnStar, with OnStar Basics core services, a three-year OnStar One plan, 5G Wi-Fi hotspot capability and a SiriusXM with 360L trial subscription.

DRIVER ASSISTANCE AND SAFETY

Super Cruise is standard on this grade and permits hands-free driving on compatible mapped roads; Adaptive Cruise Control holds a driver-selected following gap behind a detected vehicle. The braking-intervention set comprises Enhanced Automatic Emergency Braking, Intersection Automatic Emergency Braking, Front Pedestrian and Bicyclist Braking active between 8 and 80 km/h, Rear Cross Traffic Braking and Reverse Automatic Braking, with Forward Collision Alert, Rear Pedestrian Alert and Side Bicyclist Alert giving warning-only coverage. Blind Zone Steering Assist with Trailering both alerts and applies a brief corrective steering input, and extends its monitored zone to trailer length. The Safety Alert Seat signals hazard direction by vibrating the left, right or both sides of the driver's cushion. Also standard are Driver Attention Assist, Traffic Sign Recognition, HD Surround Vision, Enhanced Automatic Parking Assist which steers, brakes and shifts into a detected parallel or perpendicular space, a Rear Camera Mirror, Hitch Guidance, Hitch View, a tire pressure monitoring system, Rear Seat Reminder, Buckle to Drive and Teen Driver. Passive protection is a seven-airbag system: frontal airbags for driver and front passenger, seat-mounted side-impact airbags for driver and front passenger, a driver inboard seat-mounted side-impact airbag and head-curtain airbags for the front and rear outboard seating positions, with a front outboard Passenger Sensing System and status light. The LATCH child restraint anchor system is fitted. Security equipment is the Advanced Security Package with door lock and latch shields, a self-powered content theft-deterrent alarm, glass breakage, interior movement and inclination sensors, an electrical theft-deterrent system and a steering column lock. Note that GMC Canada's feature matrix marks Lane Keep Assist with Lane Departure Warning and the standalone Lane Change Alert as not applicable to the Denali Ultimate grade, where Super Cruise and Blind Zone Steering Assist with Trailering take their place; neither is therefore claimed here.

TOWING AND CAPABILITY

The Max Trailering Package is standard on this grade. It brings an integrated trailer brake controller whose gain and output are shown in the Driver Information Centre, the Smart Trailer Integration Indicator, Hitch View, Blind Zone Steering Assist with Trailering and an extra-capacity cooling system with gasoline engines. Trailering hardware is a hitch platform with a 2-inch receiver and a seven-wire harness with seven-pin connector for trailer lights and brakes. Trailer sway control monitors steering input and applies the trailer brakes to damp sway. Gross combined weight rating is 6,577 kg (14,500 lb). GMC Canada does not publish a maximum trailer weight for this configuration on the configurator specification sheet, so no towing figure is stated here; it should be confirmed against the Canadian order guide before it is quoted. Off-road capability rests on the Active Response 4WD system with its Autotrac two-speed transfer case and electronic limited-slip differential, Hill Descent Control, and the low-speed lift of the Air Ride Adaptive Suspension. The Autotrac case also offers a neutral position for flat towing behind another vehicle.
