# 2022 GMC Yukon AT4 Finally Adds 6.2L V8 Option With 420 HP

The [GMC Yukon AT4](<https://www.thedrive.com/news/31841/the-all-new-2021-gmc-yukon-revealed>) is an off-road SUV with room for the family, plus a few friends. A stablemate to [Chevy's Z71 Tahoe,](<https://www.thedrive.com/news/31438/no-chevrolet-wont-let-you-get-a-duramax-diesel-engine-in-2021-suburban-tahoe-z71>) it gets a slew of parts intended to make it better prepared for life off the asphalt. So far, only one engine has ever been available with this trim of the truck: GM's 5.3-liter V8. That's changing for 2022, though.

Following the logic of "bigger is better," GMC has decided to throw the 6.2-liter V8 in with the [AT4 trim,](<https://www.thedrive.com/news/31821/2021-gmc-canyon-at4-isnt-quite-the-colorado-zr2-twin-we-hoped-for>) as [*GM Authority*](<https://gmauthority.com/blog/2021/08/2022-gmc-yukon-at4-gets-optional-6-2l-v8-engine/>) writes. Packing 420 horsepower and 460 pound-feet of torque, the larger lump offers a boost of 65 horsepower and 77 pound-feet over the 5.3-liter.

GMC's decision not to include the 6.2-liter V8 in the AT4 trim was always a bit strange because it does offer the bigger V8 in the Denali trim of the truck. It's also worth noting that the off-road trim is not available with the 3.0-liter Duramax diesel option; that's because the rig's [unique front fascia](<https://gmauthority.com/blog/2020/05/2021-gmc-yukon-at4-wont-offer-diesel-powerplant/>) would apparently obstruct the engine's intercooler.

The Detroit automaker has yet to announce pricing for the 6.2-equipped AT4; however, the truck currently starts at $66,620 with the 5.3-liter. On the higher Denali trim, the big V8 carries a $1,625 premium over the 3.0-liter Duramax, which itself is $870 more expensive than the 5.3-liter on the SLT trim. We might expect the 6.2-liter V8 to carry a premium of around $2,500 over the standard car by that logic, although it will ultimately be up to GMC how to price it when the new model year comes around.

***Update at 2:40 p.m. on 08/23/2021: A representative from Chevy has confirmed that the 6.2-liter V8 will be available in the Tahoe/Suburban Z71, along with the RST and Premier trims. However, there are still no plans to put the 3.0L Duramax in the Z71.***
