2023 GMC Yukon XL

RUGGED, LUXURIOUS, TRAIL-READY, NONSMOKER, GENUINE OFF-ROAD CAPABILITY! AT4 sits as GMC's dedicated off-road trim across the lineup, and this Yukon XL brings that genuine trail capability to a full-size three-row SUV. Finished in Summit White, this AT4 pairs the upgraded 6.2L V8 with a panoramic sunroof and power second-row bucket seats. Why Shoppers Buy This Model The Yukon XL AT4 stands apart in the full-size SUV segment by offering genuine off-road hardware, not just badging, on a vehicle most buyers choose for family duty. Its high-approach-angle front fascia and heavy-duty front skid plate give it a real 32-degree approach angle, while the Autotrac 2-speed transfer case with a dedicated 4LO range provides genuine low-speed torque for rock crawling or pulling heavy loads up a slippery boat ramp. The XL's 134-inch wheelbase adds the most spacious interior in its class, giving families genuine third-row room without sacrificing any of that off-road capability.

Standard Features AT4 sits between Elevation and Denali in the Yukon XL lineup, and it shows in the details: heated and ventilated front seats, a heated second row, and a power third row all come standard here. Tri-zone automatic climate control, a 12-inch digital driver display, and a 10.2-inch touchscreen with Bose audio round out a trim built for buyers who want real off-road capability without sacrificing family-hauling comfort.

The 10-speed automatic transmission shifts smoothly across a wide range of conditions, while the Autotrac 2-speed transfer case with a dedicated 4LO range gives this Yukon XL genuine low-speed torque for serious off-road use. Hill Descent Control automatically manages braking on steep declines, letting the driver focus entirely on steering. Exterior Features Summit White gives this Yukon XL a clean, commanding presence, and it's paired here with AT4's high-approach-angle front fascia, heavy-duty front skid plate, and signature red recovery hooks for a genuinely purposeful off-road stance. Goodyear all-terrain tires on 20-inch 6-spoke machined aluminum wheels round out a look built for real trail use, not just styling. Interior Features Step inside and the heated and ventilated front seats immediately add real comfort in any season, while the heated second row keeps rear passengers just as comfortable. The installed power dual-pane panoramic sunroof brings abundant light into all three rows, and the power-release second-row bucket seats make third-row access genuinely easier than a standard bench. Infotainment Features A 10.2-inch touchscreen with Google built-in anchors the dashboard, running wireless Apple CarPlay and Android Auto so smartphones connect without extra hassle.
