2021 GMC Yukon AT4

First report: Lots of towing to break it in right

- JASON GONDERMAN

We love this time of year as we get to introduce the newest additions to our long-term test fleet. Coming off its recent win of our 2021 SUV of the Year test, we're excited to spend the next 12 months living with GMC's all-new Yukon AT4.

Aside from the exterior color, we ordered our long-term Yukon AT4 exactly as the one we had tested. GMC packs the AT4 with loads of standard features, which include the likes of magnetic ride control, hill descent control, a full complement of skid plates, 20-inch aluminum wheels, and all-terrain tires. The interior features a nine-speaker Bose audio system, tri-zone automatic HVAC system, leather seating surfaces, heated and ventilated front seats, and LED lighting throughout

Our Yukon AT4 also came fitted with the AT4 Premium Plus Package, which carried a hefty $8,145 price tag (after the $1,000 AT4 Premium Plus Package discount). However, it comes with a load of impressive features.

These include a dual-pane panoramic sunroof, power assist steps, an electronic limited-slip rear differential, adaptive air ride suspension, enhanced cooling radiator, ProGrade trailering tech, head-up display, wireless Apple CarPlay, and a pair of 12.6-inch rear-seat entertainment screens. Also on the options list is the $645 Cayenne Red Tintcoat paint, $370 heated second-row bucket seats, and $350 power sliding center console.

GMC offers the Yukon AT4 with just one drivetrain option. All Yukon AT4 vehicles are four-wheel drive with the company's 5.3L V-8 engine and 10-speed automatic transmission.
