Used 2019 GMC Yukon SUV Trims Comparison

GMC offers two different engines based on trim level. SLE and SLT models come with a 5.3-liter V8 engine that produces 355 horsepower and 383 pound-feet of torque. It is paired to a six-speed automatic transmission that sends power to the rear wheels. Four-wheel drive is available with a single-speed transfer case that is optional for all trims, and a two-speed transfer case with low-range gearing is available. The Yukon Denali is powered by a 6.2-liter V8 that produces 420 hp and 460 lb-ft of torque. It comes standard with a new 10-speed automatic and rear-wheel drive. The optional four-wheel drive includes a standard two-speed transfer case.

Standard features for the SLE trim include 18-inch wheels, heated mirrors, foglights, side steps, roof rails, front and rear parking sensors, automatic wipers, cruise control, remote keyless entry and ignition, and a trailer hitch receiver with a wiring harness.

On the inside, you get tri-zone automatic climate control, a power-adjustable driver seat, 60/40-split folding second- and third-row seats, a tilt-only leather-wrapped steering wheel, OnStar communications (including a 4G LTE connection and a Wi-Fi hotspot), a 110-volt household power outlet, Bluetooth, an 8-inch touchscreen, a rearview camera, five USB ports, Apple CarPlay and Android Auto, and a Bose nine-speaker audio system with a CD player and satellite radio.

The optional Enhanced Driver Alert package adds forward collision warning with low-speed automatic braking, automatic high beams, and lane departure warning and intervention. The Convenience package adds a power liftgate, an auto-dimming rearview mirror, power-adjustable pedals and a universal garage door opener.

There are two versions of the SLT trim: SLT Standard Edition and plain-old SLT. The Standard Edition includes all of the above, along with leather upholstery, heated front seats, a power-adjustable front passenger seat and driver-seat memory functions. The SLT further gets you hands-free operation for the rear liftgate, blind-spot monitoring with rear cross-traffic alert, keyless entry and ignition, a heated and power tilt-and-telescoping steering wheel, ventilated front seats, heated second-row seats, and power-folding second- and third-row seats.

For 2019, the SLT also gets two new packages. The Graphite Edition package is basically a blackout appearance package with 22-inch wheels. Then there's the Graphite Performance Edition package, a pricey add-on that includes the upgraded engine, transmission, and suspension from the Denali along with some extra tech features such as a head-up display and navigation.

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), 20-inch wheels, xenon headlights, adaptive suspension dampers, a trailer brake controller, a head-up display, active noise cancellation, a wireless charging pad, second-row bucket seats, an upgraded driver information display, a navigation system and a 10-speaker surround-sound system.

Some features on higher-trimmed models are available on supporting models at additional cost. Optional for SLE and SLT trims is an HD Trailering package with a unique axle ratio, trailer brake controller and a self-leveling suspension. The SLT and the Denali are eligible for a sunroof, adaptive cruise control with automatic braking, and a rear-seat entertainment system. The Denali also offers power-retractable side steps.
