The 2014 GMC Yukon XL is a model within the fifth-generation Yukon lineup. This extended-length full-size SUV comes in three trims: SLE, SLT, and the luxurious Denali. Depending on the trim, it is equipped either with a 5.3L V8 producing 320 hp or a 6.2L V8 in the Denali variant churning out 403 hp. Both engines are paired with a 6-speed automatic transmission. Drivetrain options include RWD and 4WD. The Yukon XL comes standard with a six-speaker sound system, but higher trims offer a nine-speaker Bose sound system, along with a 6.5-inch touchscreen interface and navigation. Safety features include standard stability control and optional blind-spot warning system. This model year saw few changes, as a redesigned Yukon was set for 2015.
