The 2027 GMC Yukon runs 121.0 inches of wheelbase and 210.1 inches overall, seats up to 8 with 122.8 cu ft of max cargo room, and offers three engines from 355 to 420 horsepower. None of it changed from 2026: the 2027 Yukon carries the identical platform, dimensions and engine lineup. For trim positioning and pricing, see the Trims and Pricing page; for the buying overview, see the Overview; and for last year's identical spec sheet, our 2026 Yukon research hub is still live.

Engine Specifications
5.3L V8 (standard, Elevation and AT4)
| Spec | Value |
|---|---|
| Horsepower | 355 hp |
| Torque | 383 lb-ft |
| Transmission | 10-speed automatic |
| Fuel | Regular unleaded (E15 rated) |
This is the base engine on the two entry trims, and the one most Elevation and AT4 buyers drive off the lot without upgrading.
6.2L V8 (standard, Denali and up)
| Spec | Value |
|---|---|
| Horsepower | 420 hp |
| Torque | 460 lb-ft |
| Transmission | 10-speed automatic |
The 65-hp jump over the 5.3L is the single biggest reason Denali buyers notice a difference behind the wheel compared to an Elevation or AT4.
3.0L Duramax turbo-diesel (available, every trim)
| Spec | Value |
|---|---|
| Horsepower | 305 hp |
| Torque | 495 lb-ft |
| Transmission | 10-speed automatic |
Exterior Dimensions
| Dimension | Value |
|---|---|
| Length, overall | 210.1 in |
| Width (without mirrors) | 81.0 in |
| Height, overall | 76.5 in |
| Wheelbase | 121.0 in |
| Ground clearance (Denali Ultimate 4WD) | 7.3 in |
| GVWR (standard / available) | 7,400 pounds / 7,600 pounds |
Ground clearance is 7.3 inches on a Denali Ultimate 4WD, which rides on the standard Air Ride Adaptive Suspension. Ask our sales team about the figure on the specific trim and suspension you're considering.
The width figure matters more than most buyers expect: at 81.0 inches without mirrors, a Yukon clears a standard single garage door but leaves little margin in a shared two-car bay, and mirrors typically add another 8-9 inches folded out. GVWR steps from a standard 7,400 pounds to an available 7,600 pounds on certain configurations, which raises the payload ceiling for buyers who load up a trailer tongue or a loaded cargo area on top of passengers.
| Trim | Curb weight |
|---|---|
| Elevation (base RWD) | 5,383 pounds |
Interior Dimensions
| Row | Headroom | Legroom | Shoulder room | Hip room |
|---|---|---|---|---|
| Front | 42.3 in | 44.5 in | 65.5 in | 61.5 in |
| Second row | 38.9 in | 42.0 in | 64.7 in | 61.3 in |
| Third row | 38.2 in | 34.9 in | 62.7 in | 49.4 in |
Cargo volume: 122.8 cu ft behind the first row, 72.5 cu ft behind the second row, and 25.5 cu ft behind the third row with all seats in use. Seating capacity is 8 across the lineup, dropping to 7 on Denali Ultimate with the available second-row executive seating package, which trades the middle bench for two captain's chairs. Third-row shoulder and hip room (62.7 in and 49.4 in) run noticeably tighter than the front two rows, which is typical for a three-row SUV's rearmost seat and worth knowing if you regularly carry three adults back there rather than two.
Capacity and Capability
Properly equipped, the 2027 Yukon tows up to 8,400 lbs; the exact rating depends on engine, drivetrain and trailering equipment. Max payload is 2,017 pounds on the standard configuration, against a 7,400-pound GVWR and a 14,000-pound GCWR for trailer-plus-truck combinations. A Denali Ultimate 4WD 6.2L, one of the heavier configurations in the lineup, is rated for up to 8,000 lbs as-configured, a real-world reminder that the 8,400-lb ceiling belongs to specific lighter configurations, not every truck on the lot.
Wheels, Tires, and Brakes
| Trim | Wheels |
|---|---|
| Elevation | 20-in Satin Graphite |
| AT4 | 20-in Carbon Flash Metallic, all-terrain tires |
| Denali | 20-in standard; 22-in and 24-in available |
| AT4 Ultimate | 20-in |
| Denali Ultimate | 24-in After Midnight Metallic aluminum |
Brakes: 4-wheel antilock disc brakes are standard across the lineup, with a front 6-piston Brembo brake upgrade with color-matched rear calipers available for buyers who want more stopping power under load. A mechanical limited-slip rear differential is standard, which helps put power down on loose or wet surfaces even on the RWD-available trims. AT4's all-terrain tires trade a small amount of on-road refinement for real capability on the gravel roads common around the Ouachita National Forest; every other trim runs a highway-oriented all-season tire matched to its wheel size. The same GVWR and towing figures hold on the long grades through the Ouachita Mountains as they do on flat commutes between Bryant, Arkadelphia and Hope.
Fuel Economy and Range
| Engine | Drive | City / Hwy / Combined |
|---|---|---|
| 5.3L V8 | 2WD | 15 / 20 / 17 |
| 5.3L V8 | 4WD | 15 / 19 / 17 |
| 6.2L V8 | 2WD | 15 / 20 / 17 |
| 6.2L V8 | 4WD | 14 / 18 / 16 |
| 3.0L Duramax | 2WD | 21 / 26 / 23 |
| 3.0L Duramax | 4WD | 20 / 24 / 22 |
Fuel tank capacity is 24.0 gallons across the lineup. The diesel's combined-economy advantage over the 5.3L V8 runs roughly 30% in 2WD trim, the biggest single reason tow-heavy buyers spec it despite the upcharge.

Safety and Compliance
Standard on every trim: Enhanced Automatic Emergency Braking (radar and camera-based, active above 2 mph), Front Pedestrian and Bicyclist Braking (5-50 mph, with reduced performance at night or in low visibility), Intersection Automatic Emergency Braking, HD Surround Vision for parking, and IntelliBeam automatic high beams above 25 mph. Available: Blind Zone Steering Assist, which can provide a brief steering correction when a vehicle is detected in the lane you're entering, and Enhanced Automatic Parking Assist, which can steer, brake and shift into a detected space while you stay in the driver's seat. Performance of every driver-assistance feature can be affected by visibility, weather and road conditions, and none of these systems replace an attentive driver.

What These 2027 GMC Yukon Numbers Mean in Practice
| Figure | What it means |
|---|---|
| 81.0 in wide (without mirrors) | Fits a standard 9-ft-wide single garage bay with mirrors folded; check a two-car shared bay for tight clearance |
| 210.1 in long | About 17.5 ft; needs a full-size garage bay or standard driveway parking, not a compact spot |
| 122.8 cu ft max cargo | Enough for a week of luggage for a family of six with all seats folded flat |
| 8,400 lbs max towing | Covers most bass boats, pontoon boats and mid-size travel trailers common at area lakes, properly equipped |
| 34.9 in third-row legroom | Comfortable for teenagers and adults on shorter trips, tighter than the second row on a long haul |
