SLE

What a start to the Yukon on this SLE trim. An SUV the Yukon is, but practically a truck thanks to its large size, especially on the Yukon XL, along with its new independent rear suspension that adds more space and invites a smoother ride. While incredibly similar to its related SLT trim, there are a few differences between the two that add up. 18-inch wheels are found on the SLE, compared to the 20-inch variants of the upgraded SLT, the most obvious exterior cue. Other features that the SLE doesn’t possess include no power liftgate, navigation, or auto-dim mirror, and only with a 6-speaker sound system compared to the SLT’s Bose 9-speaker system. Even still, a mighty premium base trim level the SLE is, and a grand introduction to the Yukon & XL trim world.

Highlighted features:

• 18-inch 6-spoke machined aluminum wheels
• 5.3L V8 engine
• 355 horsepower, 383 lb-ft of torque
• 10-speed automatic transmission
• Best-in-class max cargo volume behind front row of Yukon XL with 4,097 L (144.7 cu-ft)

SLT

The SLT sits pretty similar to the SLE, but with, obviously, the aforementioned features available here, like 20-inch aluminum wheels, power liftgate, auto-dim rearview mirror and 9-speaker Bose audio system. Where it further separates itself from its base-level brethren is the additional package it has available to be added on. While the SLE only has the ProGrade Trailering System, Cargo Convenience, Max Trailering and Performance Upgrade, the SLT has 3 more available. These packages are Illumination (adds illuminated front and mirror GMC emblems), Rear Media and Nav (adds rear media system and front navigation) and the SLT Luxury (adds a load of premium features like HD Surround Vision, power tilt steering, Rear Pedestrian Alert and much more). Enjoy a solid upgrade with the SLT, and more ability to customize with additional features to your liking.

AT4

The off-road AT4 trim is quickly finding its way across the entire GMC lineup, and with the new Yukon it gloriously finds itself at home here. The AT4 trim on the Yukon slightly redesigns the exterior with a unique front fascia featuring red tow hooks and an approach angle capability nearing 32°. Perfect for getting a smooth ride no matter the terrain is an available Four-Corner Air Ride Adaptive Suspension, as well as the expected Active Response 4WD to handle those adventurous elements that the AT4 is made for. If you’re one to want to take on the road less travelled in your SUV, GMC has created the perfect off-road trim for you in the form of the AT4.
