GMC Yukon Denali

2025 GMC YUKON DENALI 6.2L V8 4WD — US SPECIFICATION

ENGINE AND DRIVETRAIN

The Yukon Denali is powered by GM's L87 6.2-litre naturally aspirated EcoTec3 V8, the standard and fitted engine on the Denali grade and the engine confirmed on this unit. It displaces 6,162 cc and 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, with a Traction Select system including tow/haul mode and an Electronic Precision Shift selector. Automatic Stop/Start is standard and carries a disable button.

Four-wheel drive is standard on this configuration and is delivered by an Autotrac single-speed transfer case, which detects wheel slip and transfers torque to the front axle before returning automatically to two-wheel drive, and which can also be locked into four-wheel drive manually. This is the Denali grade's standard driveline; the two-speed active transfer case and the Active Response 4WD system are optional on this grade and are not indicated as fitted to this unit. Traction at the rear axle is managed by a mechanical limited-slip differential, not the electronic limited-slip unit used on the Ultimate grades. The rear axle ratio is 3.23. Supporting hardware includes an external auxiliary transmission oil cooler, an external engine oil cooler, a 220-amp alternator, a 730 cold-cranking-amp heavy-duty battery, an engine air filtration monitor and a dual-outlet exhaust. The engine is certified for E15 gasoline.

Fuel tank capacity is 91 litres (24.0 US gallons). The EPA ratings GMC publishes for this configuration are 14 mpg city, 18 mpg highway and 16 mpg combined, equivalent to 16.8, 13.1 and 14.7 L/100 km, giving published cruising ranges of 541 km (336 miles) city and 695 km (432 miles) highway. GM does not publish a tailpipe CO2 figure on the US features-and-specifications sheet for this configuration, and a US test-cycle consumption figure cannot be converted into a WLTP-equivalent CO2 rating, so no CO2 value is stated here.

CHASSIS, STEERING AND BRAKES

Suspension is fully independent: front coil-over-shock and rear multi-link with coil springs. Magnetic Ride Control is standard on the Denali grade and is confirmed on this unit by the seller's own description. It reads each wheel independently and adjusts damping every millisecond by altering the magnetorheological damper fluid electrically rather than by moving valves. The four-corner Air Ride Adaptive Suspension, which replaces the coil springs with variable-rate air springs and adds selectable ride height, arrives only with the optional Premium Capability Package with Active Response 4WD; it is available on this grade and is not indicated as fitted.

Steering is power assisted through a power tilt and telescoping steering column. Braking is by four-wheel antilock discs, supported by StabiliTrak electronic stability control with traction control, Hill Start Assist and trailer sway control. Hill Descent Control is not standard on the Denali grade — it arrives with the optional Max Trailering Package — and is not indicated as fitted.

Wheels are 20-inch six-spoke multi-dimensional polished aluminium, the Denali grade's standard fitment, confirmed on this unit by the seller's description of 20-inch polished aluminium wheels. Tyres are P275/60R20 all-season blackwall. A 17-inch full-size steel spare wheel with a P265/70R17 all-season blackwall tyre and a spare tyre carrier are standard. The 22-inch and 24-inch wheel options offered on this grade are therefore not fitted.

DIMENSIONS AND CAPACITIES

Overall length is 5,337 mm (210.1 in), width across the body excluding mirrors is 2,057 mm (81.0 in) and overall height is 1,943 mm (76.5 in), on a 3,073 mm (121.0 in) wheelbase. GM's US features-and-specifications data returns no published value for front or rear ground clearance on this model line, so no ground clearance figure is stated here.

Kerb weight as specified for this trim is 2,613 kg (5,760 lb), split 1,332 kg (2,937 lb) front and 1,281 kg (2,823 lb) rear. Payload as specified is 880 kg (1,940 lb). Gross vehicle weight rating is 3,493 kg (7,700 lb). Gross axle weight ratings are 1,678 kg (3,700 lb) front and 1,950 kg (4,300 lb) rear, and the gross combined weight rating is 6,350 kg (14,000 lb). The 7,700 lb GVWR is the self-consistent figure: it is confirmed twice over by GM's own data, once as trim kerb weight plus as-specified payload (5,760 + 1,940) and once as base kerb weight plus maximum payload (5,580 + 2,120). GM separately labels the GVWR option code on this vehicle "7,600 lbs. GVWR", which reconciles with neither arithmetic; that label is disregarded here.

Cargo volume is 722 litres (25.5 cu ft) behind the third row, 2,053 litres (72.5 cu ft) behind the second row and 3,477 litres (122.8 cu ft) behind the first row, with a load width between the wheelhouses of 1,257 mm (49.5 in). Interior room measures 1,074 mm head and 1,130 mm legroom in the first row, 988 mm and 1,067 mm in the second row, and 970 mm and 886 mm in the third row.

EXTERIOR

The exterior finish is Volcanic Red Tintcoat over a Jet Black interior. Lighting is LED throughout: LED headlamps with animated lighting, LED tail lamps with animated lighting and LED fog lamps, with IntelliBeam automatic high-beam control. The tailgate is an AutoSense power liftgate with a programmable memory height, obstacle detection and walk-away close. Mirrors are body-colour, heated and power-adjustable with driver-side auto-dimming, under body-colour caps. Brightwork comprises bright roof-mounted side rails, chrome door handles with a body-colour strip and satin chrome bodyside mouldings. Black assist steps are fitted. Glazing is acoustic laminated, with laminated front door glass, a windshield shade band and deep-tinted rear glass. Rainsense automatic wipers, a rear intermittent wiper and a rear camera washer are standard, as are upper active aero shutters and a dual-outlet exhaust.

The panoramic power sunroof and the power-retractable assist steps with LED perimeter lighting are options on this grade. Neither appears in the seller's equipment list or description, and neither is treated as fitted here.

INTERIOR AND SEATING

Seat trim is perforated leather-appointed in Jet Black. Front seats are buckets with 8-way power adjustment for driver and front passenger, 4-way power lumbar control for both, and heating and ventilation for both — the seller's description confirms heated and ventilated front seats on this unit. Driver memory settings are standard, as is a heated steering wheel and heated second-row outboard seats.

The second row is the Denali grade's standard power-release bucket seat arrangement; a power-release 60/40 split-folding second-row bench is a factory alternative on this grade, and the listing does not state which of the two is fitted, so the passenger count is not asserted here. The third row is a power 60/40 split-folding bench, confirmed by the seller's reference to power-folding third-row seating. A power-sliding centre console is standard. The executive second-row seating package — power-adjustable, ventilated and massaging second-row seats — is not offered on the Denali grade at all; it is exclusive to the Denali Ultimate.

Climate control is tri-zone automatic with rear air conditioning, a cabin air filter and a rear window defogger. Other standard interior equipment includes a wrapped steering wheel with mounted controls, a power tilt and telescoping column, carpeted floor covering and mats, bright sill plates, illuminated visor mirrors, an inside auto-dimming rearview mirror, 120-volt power outlets, a universal home remote, keyless open and keyless start, remote start, an electrical theft-deterrent system with steering column lock, and power windows with driver and front passenger express up/down and rear express-down.

INFOTAINMENT AND CONNECTIVITY

The centre display is a 16.8-inch diagonal advanced colour LCD with Google built-in compatibility, carrying navigation capability, connected apps, per-driver personalised profiles, natural voice recognition, phone integration and the climate and vehicle setting controls; the seller lists a navigation system on this unit. It is joined by an 11-inch diagonal colour Driver Information Centre and a 15-inch diagonal multicolour head-up display. The head-up display is standard equipment on the Denali grade for 2025 — it is not an Ultimate-only item — and the seller's description confirms it on this unit.

Audio is the Bose CenterPoint Surround 10-speaker system, matching the seller's reference to a premium 10-speaker audio system. Wireless Apple CarPlay and wireless Android Auto are supported for compatible phones, alongside wireless phone charging, front console and third-row USB ports, 5G Wi-Fi hotspot capability, SiriusXM with a 360L trial subscription, and OnStar services capability with GMC Connected Access. The Rear Seat Media System is bundled into the optional Advanced Technology and Denali Reserve packages and is not indicated as fitted.

DRIVER ASSISTANCE AND SAFETY

Seven airbags are fitted: 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 covering the front and rear outboard seating positions, with a front outboard Passenger Sensing System and status light for the front passenger airbag.

Standard driver assistance on this grade comprises Enhanced Automatic Emergency Braking, Intersection Automatic Emergency Braking, Front Pedestrian and Bicyclist Braking, Side Bicyclist Alert, Forward Collision Alert, Rear Cross Traffic Braking, Rear Pedestrian Alert, Reverse Automatic Braking, Adaptive Cruise Control, HD Surround Vision, Enhanced Automatic Parking Assist, Traffic Sign Recognition, IntelliBeam, the Safety Alert Seat and Hitch Guidance.

Lane Keep Assist with Lane Departure Warning (enhanced) and Blind Zone Steering Assist are both standard on the Denali grade. This is worth stating explicitly because it does not hold across the Yukon range: on the Denali Ultimate and AT4 Ultimate grades GM lists both systems as not available, because Super Cruise and Blind Zone Steering Assist with Trailering take their place. On this Denali the two base systems are the fitted configuration, and the trailering-extended blind-zone system is an option that is not indicated as fitted.

Super Cruise hands-free driver assistance is available on the Denali grade only as part of the Advanced Technology Package or the Denali Reserve Package. Neither package appears in the seller's equipment list or description, and Super Cruise is not claimed for this unit. The Rear Camera Mirror and the Advanced Security Package travel in the same packages and are likewise not claimed.

Further standard safety equipment includes StabiliTrak electronic stability control with traction control, four-wheel antilock disc brakes, Hill Start Assist, trailer sway control, a direct tyre pressure monitoring system, Teen Driver, Buckle to Drive, the Rear Seat Reminder, the LATCH child restraint system and rear child security door locks.

TOWING AND CAPABILITY

Trailering equipment is standard on this configuration and comprises a trailering hitch platform, a 2-inch trailering receiver, and a 7-wire harness with a 7-pin connector for trailer lights and brakes; the seller's equipment list confirms a tow hitch on this unit. Hitch Guidance and trailer sway control are standard, and the tow/haul mode is part of the standard Traction Select system.

The gross combined weight rating for this configuration is 6,350 kg (14,000 lb) against a gross vehicle weight rating of 3,493 kg (7,700 lb) and a kerb weight of 2,613 kg (5,760 lb). No maximum trailer weight is stated here. The seller's description quotes a towing capacity of up to 8,400 lb, but that is a model-line figure that depends on the optional Max Trailering Package; it cannot be reconciled with the 14,000 lb gross combined weight rating and 5,760 lb kerb weight that GM publishes for this exact configuration, so it is not carried forward.

The Max Trailering Package — which adds an integrated trailer brake controller, Hitch View, Blind Zone Steering Assist with Trailering, a Smart Trailer Integration Indicator, an extra-capacity cooling system and, on four-wheel-drive models, a two-speed active transfer case with Hill Descent Control — is available on this grade and is not indicated as fitted. Buyers requiring a certified maximum trailer weight should have it confirmed against the vehicle's build data before contracting.
