If you frequently need to carry plenty of cargo along with a sizable group of passengers, the full-size Yukon XL is one of the few available choices. Yukon XLs are loaded with equipment, but the sticker price rises rapidly if you select a few options – or move all the way up to the plush, top-of-the-line Denali.

If you like to breeze past gas stations without glancing down at the fuel gauge, a Yukon XL won’t bring smiles – despite the new multi-displacement system that improves fuel economy. Head-curtain airbags for all three rows are optional or included only on upper trim levels.
In the new family of more powerful V8 engines, an Active Fuel Management system switches automatically between eight- and four-cylinder operation (depending upon conditions) to reduce fuel consumption, and the Stabilitrak stability-control system now includes rollover mitigation.
Seating up to nine occupants, depending upon seating configurations for each row, the new Yukon XL delivers greater passenger comfort in a more spacious interior. A lower-positioned instrument panel helps add leg space, front seats gain fore-and-aft and recline travel and second-row seats recline further, too. There is more second-row leg and knee room, third-row headroom and second- and third-row shoulder room. The third-row seats fold flat, tumble forward and are removeable. Gloveboxes are 25-percent bigger, and available power fold-and-tumble second-row seats ease third-row access.
The new Yukon XL boasts a redesigned exterior with wraparound front and rear fascias and integrated running boards. GMC claims improved aerodynamics, helped by a sleek 57-degree windshield angle. The XL’s 130.0-inch wheelbase and 222.4-inch overall length compare to 116.0 and 202.0 inches, respectively, for regular-size Yukons. Wider tracks (three-inches greater in front) enhance stability. Doors extend over the rockers and larger headlamps deliver improved lighting spread. The XL Denali gets chrome accents, a distinctive honeycomb grille, unique headlamps with etched GMC logos, clear-lens taillamps and 18-inch polished wheels.
The Yukon XL – especially in Denali form – is a refined, if flamboyantly oversized, family and cargo hauler. With the six-speed automatic of the Denali, transmission responses are less harsh than in four-speed models, with less-noticeable delays, and a richer exhaust note emanates from the 6.2-liter V8. Despite energetic start-off acceleration, it’s not quite as vibrant when passing. Ride quality in the Denali is hardly truck-like at all, and it feels secure in curves. Expressways are the Denali’s forte, where an appealing ride blends with excellent stability and easy control.
In base SLE trim with two-wheel drive the Yukon XL 1500 starts at $38,585. A midrange SLT with two-wheel drive stickers for $42,200, while the Denali with all-wheel drive has a Manufacturer’s Suggested Retail Price (MSRP) above $51,000. Four-wheel drive adds about $2,800 to the SLE and SLT prices. The heavy-duty Yukon XL 2500 models have stickers ranging from $39,785 to $46,160. The Fair Purchase Price, which represents what consumers are actually paying, will be somewhat lower. Be sure to click on Fair Purchase Prices to check what the Yukon XL is currently selling for in your area. In terms of resale value, the Yukon XL 1500 with two-wheel drive is expected to retain 32 percent of its original value over a 60-month period; four-wheel-drive models should retain 34 percent. Those figures beat Ford’s Expedition, but fall lower than Toyota’s Sequoia and are on par with the Nissan Armada. GMC’s Yukon XL Denali should hold its value better, with 37 percent after 60 months.
The SLE includes Stabilitrak, 17-inch alloy wheels, front and rear air conditioning, heated power mirrors, roof rails, side steps and rear privacy glass. SLT versions have leather appointments and front bucket seats, head-curtain airbags, remote engine start and a cargo cover. The XL Denali includes Autoride suspension, the 6.2-liter V8, six-speed automatic transmission, a power liftgate, power release second-row fold-and-tumble bucket seats, power-adjustable pedals, heated windshield washers, an auto-dimming inside mirror, RainSense wipers, remote start, Ultrasonic Rear Parking Assist, a six-CD changer, Bose 10-speaker Centerpoint Surround Sound audio, XM Satellite Radio, "Nuance" leather-covered seats, heated first- and second-row captain’s chairs and a leather-wrapped steering wheel with genuine wood accents. All Yukon XL models have GM’s OnStar emergency and communications system.
Some tempting extras are available for the Yukon XL, including a power liftgate, sunroof, remote starting system, navigation system, DVD entertainment and heated steering wheel. Heated seats are offered for the first and second rows. Other options include power-retractable articulating assist steps (running boards), 20-inch wheels, rain-sensing wipers, Ultrasonic Rear Parking Assist, a rearview camera system and Autoride, GM’s real-time damping suspension.
Active Fuel Management TechnologyDon’t expect gas-mileage miracles from the new cylinder-deactivation system, but, when dealing with heavy vehicles, even a modest fuel-economy improvement is worth the effort.Autoride SuspensionAvailable real-time damping lets a Yukon XL cross the line from acceptable ride comfort into a tempting – perhaps even delightful – road experience. You won’t forget you’re in a truck, but an Autoride-equipped Yukon XL promises more pleasant hours on long hauls.
Under the Hood
The Yukon XL 1500 has a standard iron-block 5.3-liter V8 that produces 320 horsepower, and a 6.0-liter V8 is optional. Yukon XL Denali models have a 6.2-liter V8 that generates 380 horsepower. In the heavy-duty 2500 series, an iron-block 6.0-liter V8 makes 352 horsepower. All engines operate with Active Fuel Management technology, and the 5.3-liter V8 is available with E85 compatibility.

Essentially mechanically identical to Chevrolet’s Suburban, the Yukon XL is on what GMC calls an "all-new" full-size SUV platform. Half-ton 1500 and heavy-duty 2500-series models are available, with rear- or four-wheel drive. The standard engine size is a 5.3-liter V8, available in either gasoline or flex-fuel versions (the latter so it can operate on E85), with 6.0-liter V8s optional. Or, buyers may step all the way up to an extravagant Denali Edition with its class-leading 380-horsepower 6.2-liter V8 and six-speed automatic transmission.
