NEW FOR 2015:
-Redesigned model
The Yukon XL is a stretched version of the full-size Yukon; where the standard model shares much with the Chevrolet Tahoe, the XL is essentially a twin to the Suburban. New styling streamlines the look somewhat, but proves vehicle designers can only do so much to a vehicle shaped like a brick.
Powertrain options include 5.3L and 6.2L V8 engines; the smaller is standard in all but the top-end Denali model, which gets the 6.2L. A six-speed automatic is paired with 5.3L trucks, and Denali models use an eight-speed auto.
Trim levels include SLE, SLT and Denali. A standard-length version, simply called Yukon, is covered in a separate buyer's guide entry.
Standard features include a 4.2-inch colour driver information display, eight-inch colour touchscreen, five USB ports, 110-volt power outlet, ambient lighting, tilt steering, sliding console cover, manual fold-flat second and third-row seats, cloth seats, 10-way power adjustable driver's seat and six-way power passenger seat (a front bench seat is available), Bluetooth, black assist steps, body-colour bumpers, fog lights, heated/power-adjustable/power-folding side mirrors with driver's side auto-dimming, front and rear park assist, black roof rack side rails, locking rear differential, 18-inch bright machined aluminum wheels, cargo management system, automatic tri-zone climate control, cruise control, IntelliLink infotainment system, 4G LTE hotspot capability, nine-speaker stereo, and satellite radio.
SLT models add intelligent keyless entry and pushbutton start, electric steering wheel adjustment, heated steering wheel, leather seating, 12-way adjustable heated and cooled front seats with four-way lumbar, safety alert seat, heated and power-release second-row bench seat, power-folding third row seat, power liftgate, side mirror-integrated turn signal repeaters, rear cross traffic alert, side blind zone alert, courtesy lighting with theatre dimming, lighted door handles, footwells and in-door storage, garage door opener, wireless charging. The SLT also comes standard with a convenience package of auto-dimming rearview mirror, power-adjustable pedals, power liftgate and garage door opener; this group is optional in the SLE.
Denali trim includes the 6.2L engine and eight-speed transmission, chrome-trimmed side steps and roof rails, handsfree power liftgate, Xenon headlights and 20-inch wheels.
