2026 GMC Yukon XL Trim Options
Elevation
5.3L V8 engine · 10-speed automatic transmission · HD Surround Vision · Heated front seats
The 2026 GMC Yukon XL Elevation gives shoppers a strong starting point because it feels complete from the first drive.

Inside, heated front seats and a heated steering wheel help make daily driving more comfortable, and second-row outboard heated and power-release seats simplify access and passenger movement. HD Surround Vision is a meaningful standard feature for a vehicle of this size, giving drivers added awareness in shopping centers, school pickup zones, and tighter residential streets. Elevation also offers available Super Cruise® hands-free driver assistance technology and the available Duramax® 3.0L Turbo-Diesel engine, so shoppers can tailor the SUV toward more advanced commuting convenience or long-distance efficiency-minded capability. For many buyers, Elevation is the smart entry into Yukon XL space without giving up premium GMC character.
