Huge interior with class-leading cargo space, strong lineup of V8 engines, extensive list of optional features, seats up to nine.
Cheap interior materials, bulky size makes it unwieldy for daily use, vague steering, can't get side airbags on base model.
The 2006 GMC Yukon XL is one of our favorite big SUVs, thanks to its strong engines, smooth ride and massive cabin. Competitors may offer more conveniences and refinement, but along with its Chevy Suburban twin, the Yukon is the only SUV in its class offered in light- and heavy-duty versions.
The Yukon XL is GMC's largest SUV. Able to seat up to nine people, this is a very versatile hauler and should more than adequately serve families that have heavy-duty towing and hauling needs. Its roots can be traced back to 1936. Known as the GMC Suburban back then, this vehicle was merely a standard panel van with a few extra seats and windows. It earned a reputation as a sturdy people mover, however, and now, 10 generations later, the tradition continues with the GMC Yukon XL.
Along with the name change in 2000, the Yukon XL received a modern chassis that gave a more comfortable ride and improved overall performance. A luxurious and powerful Denali version was added a year later to give the Yukon XL more traction against a growing number of full-size luxury sport-utilities. A lineup of three V8 engines is available depending on your needs, and a laundry list of interior options allows you to add as much or as little luxury as you might want. Modern advancements like a stability control system make the Yukon XL safer than ever before. Although there are a few capable competitors out there, the 2006 GMC Yukon XL remains one of the most popular vehicles for those looking for maximum passenger capacity in a comfortable, easy-to-drive package.
2006 GMC Yukon XL models
The standard GMC Yukon XL is offered in half-ton (1500) and three-quarter-ton (2500) configurations. The 1500 models come in SL, SLE and Denali trim, while the 2500 is available in SLE trim only. Standard equipment for SL models includes tri-zone manual air conditioning, cruise control, a driver message center, keyless entry, a leather-wrapped tilt steering wheel and a CD player. The SLE is similar but grants access to additional features such as automatic climate control, leather seating, a floor console with integrated rear-passenger stereo and climate controls and an upgraded audio system via an SLT option package. Top-of-the-line Denali models come standard with just about every feature available, although items like a DVD-based entertainment system and a sunroof are still optional.
The GMC Yukon XL has a few additional features for 2006. OnStar, a tire-pressure monitor and stability control are now standard on all trim levels. Steering wheel-mounted audio controls are new this year, and the optional towing/camping exterior mirrors have been revised. Lastly, the interesting but expensive Quadrasteer four-wheel steering system has been dropped for 2006.
Performance & mpg
SL and SLE 1500 models feature a 5.3-liter V8 rated at 295 horsepower and 335 pound-feet of torque mated to a four-speed automatic transmission. The Denali and SLE 2500 models come standard with a 6.0-liter V8 rated at 335 hp and 375 lb-ft of torque. Optional on the 2500 is an 8.1-liter V8 that cranks out 325 hp and 447 lb-ft of torque. The bigger V8s get a heavy-duty four-speed automatic. Both two- and four-wheel drive are available on all models, except the Denali, which is all-wheel drive only. The GMC Yukon XL 1500 can tow up to 8,500 pounds (8,100 on the Denali). The 2500 models equipped with the 6.0-liter engine can tow up to 9,900 pounds. With the 8.1-liter engine, capacity jumps to 12,000 pounds.
The Yukon XL comes with front airbags that deploy based on crash severity, a tire-pressure monitoring system, four-wheel antilock disc brakes and the StabiliTrak stability control system. Front-seat side airbags are standard on the Denali, optional on the SLE and not available on the SL. In crash tests conducted by the NHTSA, the 2006 GMC Yukon XL received four stars (out of five) for protection of the driver and front passenger in front-impact crashes.
We're impressed with the Yukon XL's smooth, comfortable ride quality and easy-to-drive nature. Thanks to a stiff frame and a well-insulated cabin, this big SUV is generally quiet and rattle-free, making it a great long-distance cruiser. The ride of the heavy-duty three-quarter-ton models is a little less forgiving for rear-seat passengers, but they're still comfortable enough to be daily drivers.
The interior of the GMC Yukon XL is spacious with solid ergonomics and plenty of creature comforts. There's room for nine if you stick with bench seats, but ordering the optional captain's chairs drops capacity to seven passengers. Like many GMC trucks there's a little more plastic than we would like and the build quality could be better, but overall it's still a pleasant environment for a family vehicle. The Yukon XL leads the class in cargo capacity (132 cubic feet) but doesn't offer fold-flat seats unlike a few competitors.

I bought this 2006 GMC Denali back in September as a Certifed GMC. So far everything has been great no complaints. I have to disagree on what people have say about the gas. You don't buy a 5000 pound car for fuel economy. I avg 14.8 around town and 19.7 hwy. Love my car! Will buy another one

Denali 4dr SUV AWD (6.0L 8cyl 4A)
I've had my Yukon since April 04 and have not had any problems with it. It's got over 45,000 miles on it and everything is still like new. We have 4 children and often take trips that last over 5 hours each way -- the DVD player is a treasure. I love the heated seats and Stereo too!

Is it better to lease or buy a car? Ask most people and they'll probably tell you
that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make
higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand,
can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a
new car every three years or so.
