The GMC Yukon AT4 is where bold design, advanced technology, and off-road capability come together. Built for adventure with a commanding presence, the AT4 trim enhances the Yukon’s full-size SUV appeal with a distinctive blacked-out grille, red recovery hooks, and all-terrain tires. Under the hood, you’ll find a powerful 5.3L V8 engine (or available 6.2L V8), paired with a 10-speed automatic transmission for smooth, responsive performance.
