The Chevrolet and GMC full-size T1 SUV family are entering their second year on the market after what feels like a soft opening. Already, the 2022 Chevrolet Tahoe and Suburban, as well as the 2022 GMC Yukon and Yukon XL lineup are getting a new digital instrument cluster, plus a new infotainment screen, which you can read about here. Despite those big details, there’s still much more to talk about regarding these big SUVs, according to the vehicle’s official dealer order guide, and today we’d like to turn your attention to the 2022 GMC Yukon AT4.

2022 GMC Yukon AT4 Updates

Along with receiving the previously mentioned infotainment and driver display changes, the 2022 GMC Yukon AT4 will also unlock the 6.2L L87 V8 engine to customers. Previously, the 2021 Yukon AT4 was only available with GM’s 5.3L L84 V8. A perfectly fine engine, to be sure, but doesn’t quite match the macho magnificence that is the Yukon AT4. With the L87 comes 420 horsepower, and 460 lb-ft of torque. Plenty for punching the 2022 GMC Yukon AT4 through the trails. Just don’t go too fast: that tough-looking lower bash plate is actually made of plastic in lieu of steel. And, sorry diesel fans, the LM2 3.0L Duramax still isn’t available with the AT4 package.

Adding to the changes unique to the 2022 GMC Yukon AT4 is a set of 20-inch accessory wheels, carrying LPO code SEM. These dealer installed multi-spoke Gloss Black wheels will also not forgo the factory 20-inch wheels the Yukon AT4 comes with, meaning customers can take them home and fit on a different tire, if they so choose.

Minor updates include what GMC is calling “Enhanced Trailer View,” which is another dealer-installed accessory package. This gives the 2022 Yukon AT4 the nifty trailer vision camera that’s already available on the GMC Sierra 1500 pickup truck. The package includes a rear vision trailer camera, trailer assist guides, and an auxiliary trailer camera. By nature, it requires the Max Trailering package, Technology Package, and trailer tire pressure monitor sensors. The Enhanced Trailer View package is also available on the 2022 Yukon Denali.

Muscle Cars & Trucks was founded by Manoli Katakis - an automotive media veteran that has been covering the latest car news since 2009. His journalism has uncovered dozens of major product changes, updates, plans, and cancellations long before automakers were ready to make things official.

Some highlights over the years of his reporting include the uncovering of the Zora trademark before anybody else reported on the coming of a mid-engine Corvette, as well as the dead-accurate reporting of the coming of the Chevrolet Colorado ZR2, two years before it hit the market, and even before the debut of the concept vehicle. This type of reporting has immediately continued here, with reports of the original seventh-generation Camaro plans being shelved, as well as what's in store for the Chevrolet Silverado.

Some of his work can be found on massive automotive media outlets, such as Motor1. He also has been a guest on the 910AM Radio Station with Detroit News auto critic Henry Payne, as well as the enthusiast-oriented Camaro Show podcast.

Over the years, Manoli has interviewed various automotive industry titans, leaders, and people that make things happen otherwise. These include figureheads such as GM CEO Mary Barra, GM President Mark Reuss, automotive aftermarket icon Ken Lingenfelter, Dodge firebrand Tim Kuniskis, along with various chief engineers of vehicles such as the Ford F-150 & Mustang, Chevrolet Camaro & Corvette, and many more.

At MC&T, Manoli is taking his journalism expertise, deeply planted sources, driving abilities, and automotive industry knowledge to new levels, covering more vehicles and brands than ever before. This is the place where you will continue to read groundbreaking stories about American performance vehicles, pickup trucks, and sport utility vehicles. Here is where you’ll also read insights and quotes from various automotive subject matter experts on the latest relevant products, as well as some of the latest official news from their manufacturers.

Fun facts: he also once beat Corvette Racing driver Tommy Milner in an autocross with a Chevrolet Bolt EV. The biggest vehicle he’s ever driven is a John Deere mining truck. Besides a go-kart, the smallest vehicle he’s driven has been a Hyundai i10. He’s also spent time in the cockpit of various American performance vehicle icons, including the fifth-generation Chevrolet Camaro Z/28, Dodge Challenger Demon, and Ford Mustang GT350R. He has reviewed dozens of trucks, SUVs, and performance vehicles over the years.

One of his favorite new vehicles on the market today happens to be the Chevrolet Colorado ZR2 Bison. He is also a card carrying member of the Sports Car Club of America, and regularly participates in Detroit Region autocross events.
