The GMC Yukon is a full-size SUV with traditional body-on-frame construction that trades on-road performance for excellent off-road and towing capabilities. Mechanically identical to the Chevrolet Tahoe, the Yukon is available with numerous trim packages and can also be had as the long-wheelbase Yukon XL and the luxurious Yukon Denali.
The standard-size Yukon features six-person seating capacity, with a third row seat as an option, giving it the ability to carry seven passengers.
The standard motor is a 5.3-liter V8 that makes 320 horsepower at 5,200 rpm and 340 lb-ft at 4,200 rpm. The motor is available in a FlexFuel version, and can be paired with either two- or four-wheel drive.
The 2WD version of the Yukon with the 5.3-liter V8 is rated at 14 mpg city and 20 mpg on the highway. The 4WD version drops to 19 on the highway, but maintains the 14 city rating.However, if one opts for the Yukon XFE, fuel economy is bumps to 15 city and 21 highway, and the package is only available on 2WD models.
Regardless of whether they are equipped with two- or four-wheel drive, all Yukons now come with a standard six-speed automatic transmission.
Two trims exist: SLE and SLT, with two package options each. Standard equipment includes dual-zone air conditioning, an AM/FM/CD/MP3 stereo, cruise control, body-color side steps, head curtain air bags, power door locks and windows, seating for six on two bench seats, a tire pressure monitoring system and XM radio with a 3-month trial period.
The SLE trim level comes with cloth seats, while the SLT features leather and a higher level of standard equipment.
Maximum towing ability is 8,500 lbs when buyers opt for a 2WD model, while for 4WD models the max tops out at 8,200 lbs.
All Yukons come standard with dual front, front side and full-length side-curtain airbags in addition to traction and stability control systems.
Despite rising gas prices and looming government fuel economy regulations, buyers can still find a range of brand new full-size, body-on-frame SUVs. Besides the Yukon, these include the Ford Expedition, the Toyota Sequoia and the Nissan Armada .
