2022 GMC Yukon AT4 Finally Adds 6.2L V8 Option With 420 HP
It’s got 65 more horsepower than the 5.3-liter, along with an extra 77 pound-feet of torque.
The GMC Yukon AT4 is an off-road SUV with room for the family, plus a few friends. A stablemate to Chevy's Z71 Tahoe, 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, as GM Authority 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 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.
