The standard engine is the 5.3-liter V8 that produces 355 horsepower and 383 lb-ft of torque and is paired with a six-speed automatic transmission. Available on the SLT and standard on the Denali is a 6.2-liter V8 that produces 420 hp and 460 lb-ft of torque, paired with a 10-speed automatic. Rear-wheel drive is standard, while four-wheel drive is optional.

Standard feature highlights for the SLE trim include tri-zone automatic climate control, a tilt-only leather-wrapped steering wheel, OnStar communications (including a 4G LTE connection and a Wi-Fi hotspot), an 8-inch touchscreen, Apple CarPlay and Android Auto, and a Bose nine-speaker audio system. The optional Enhanced Driver Alert package adds a few advanced driver safety aids, while the Convenience package provides enhancements such a power liftgate and an auto-dimming rearview mirror.

There are two versions of the SLT trim: the SLT Standard Edition and the plain-old SLT. The Standard Edition includes all of the above, along with extras such as leather upholstery and heated front seats. The SLT further loads up the Yukon with keyless entry and ignition, a heated and power tilt-and-telescoping steering wheel, ventilated front seats, and power-folding second- and third-row seats, among other features.

Compared to the SLT, the top-of-the-line Denali trim adds the larger engine and 10-speed transmission (with low-range gearing on 4WD models), adaptive suspension dampers, a trailer brake controller and more technology features.

Most top-of-the-line features are available as optional extras on lower trims in some shape or form. Optional for SLE and SLT trims is an HD Trailering package.
