GM’s Recommended 2022 GMC Sierra AT4 Powertrain Mix29
Back in October, General Motors debuted the fully refreshed 2022 GMC Sierra 1500, unveiling a long list of updates and changes for the popular pickup truck. Now, GM Authority has learned General Motors’ recommended powertrain mix for dealers stocking the 2022 GMC Sierra AT4.
The 2022 GMC Sierra AT4 is available with two engine options, including the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm, and the 3.0L I6 LM2 turbodiesel Duramax, rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque. Both engines connect to the GM 10-speed automatic transmission, as well as a four-wheel drive system.
With regard to GM’s recommended powertrain mix for the refreshed 2022 GMC Sierra AT4, the 6.2L V8 L87 is most heavily weighted at 60 percent, while the 3.0L I6 LM2 is recommended at 40 percent.
Notably, the new GMC Sierra AT4X trim level is only available with a single engine option, namely the naturally aspirated 6.2L V8 L87. Elsewhere in the lineup, the Sierra 1500 is available with the turbocharged 2.7L I4 L3B gasoline engine and naturally aspirated 5.3L V8 L84 gasoline engine.
For those readers who may have missed it, GM Authority has also covered GM’s recommended powertrain mix for the refreshed 2022 GMC Sierra SLE, SLT, and Denali.
As a reminder, the 2022 GMC Sierra AT4 is an off-road-oriented trim level that slots in below the even-more-capable AT4X with regard to the Sierra 1500 lineup. Standout features for the AT4 include a two-inch factory suspension lift with off-road suspension and Rancho monotube shocks, as well as a two-speed AutoTrac transfer case, an automatic locking rear differential, and underbody skid plates to protect vulnerable mechanical components.
The AT4 also features 18-inch machined aluminum wheels with Dark Grey accents, Mud-Terrain Goodyear Wrangler DuraTrac tires, and unique AT4 badging.
Under the body panels, the refreshed 2022 GMC Sierra 1500 rides on the GM T1 platform. Production takes place at the GM Silao plant in Mexico and the GM Fort Wayne plant in Indiana.

I do not understand why they didn’t put the DURAMAX 3.0 in the AT4X. There’s no different “fascia” or bumper restricting the engine. A locking differential does NOT take up space more than the regular drivetrain.
They literally put the DURAMAX 2.6 in the Colorado ZR2 which has locking differentials.
So to not add it as an option to the AT4X but have it available for the AT4 doesn’t make any sense
2.8 for the Colorado ZR2 my bad
The AT4X is meant to be a near competitor with the Raptor (even though it’s underpowered). The Duramax would have detracted from that marketing. Besides, a Duramax based AT4 is a pretty damn good truck IMO. All you’re missing are the shocks, a slightly bigger lift, and those massaging seats. Frankly, I think the AT4X is overpriced for what it is.
They are ALL OVERPRICED!!!
The AT4 doesn’t come with the select lockable differential. Instead you have to literally lose control for the g-80 to kick in and by then you’ve peeled out off the cliff
No D-Max in the AT4X is the only reason I haven’t pulled the trigger on one. I want the upgrades that are exclusive to the -X, but I want the diesel, too – I don’t give a damn that it has “less power” than a Raptor.
The owners of the 6.2 pollution mill can enjoy having their wallets bleed in pure agony.
Don’t cry for a bailout when you are bankrupt.
It’s my opinion that if they can afford that level of truck, gas $$$ is not a problem
Good to know Karen.
It’s a good looking truck in that color. Blacking the front gtill does not ehance the huge grill in chrome unless you like that big chrome face.
If you vote right in November, you could see gss prices go down easing your decision about buying this good looking truck. Don’t forget 2024. This is my opinion based on the last 14 months versus the 45 4 years. JMO…
I do agree with $4.00 to $8.00 a gal right now is atrocious right now and can get even worse into 2023. Filling a 36 gal tank is crazy at these prices as well as getting 17mpg to 21mpg just incresses your frequency at the pump.
On the other hand, Silverado EV is damn expensive and of today, not useable as a work, just usable as a grocery getter and picking up minor materials at Home Depot around your small city. Good luck finding a charger station in the burbs and don’t get caught in the inner city. The inner city here, car jacking and thefts. If you need a charge, it’s best to leave it of get it towed asap.
Things to consider when you’re gung ho on EVs.
If only politics has anything to do with gas prices. Current gas prices are completely due to corporate greed and filling their own pockets while using the war in Ukraine as an excuse.
Really??? I only see politicians using Ukraine as an excuse for oil prices – not business people. And, if there’s so much “corporate greed” where was it when gas was $1.78/gallon a little over a year ago??
Maybe the biggest question should be “What’s the difference in the world between $4.59 gas (today) and $1.78 gas (November 2020)?” Same corporations, but different politicians. Math isn’t hard.
National politicians don’t determine global crude prices, though they can nick them for their own countries from time to time. The difference in those two situations was the negative price of crude due to a little thing called a pandemic suppressing fuel use. Economics isn’t that hard, either.
I worked for Kerr-McGee in it’s heyday, later acquired by Anadarko, which was acquired by Occidental. Oil prices are determined purely by produced inventories in transit and storage. Commodity traders determine benchmark prices based on inventory and demand flows. Futures contracts are in play. Big money is made and lost through zero sum gains.
Trump opened leasing and drilling. This increased flows. The low oil prices were pre pandemic. Also after the Moncondo blowout in the Gulf during Obama, Trump opened up deepwater offshore off the continental shelf in the Gulf. These wells are barnburner producers at 10K to 15K+ barrels of oil per day. Cost payback was 6 months of production. Kerr-McGee had a benchmark payback of 38% minimum ROI. Fossil fuels will rule for the next several thousand years.
The subsea oil strata is unlimited. That’s why China wants the South China Sea.
This faddish pipedream of electric vehicles and green earth is a political ploy to sucker the naive American public in voting for the Dems.
And I’m a degreed geologist from the University of Texas with decades of professional experience owning my own firm – with a partner who cut his teeth in the Gulf with BP. And you know as well as I do that opening up leases that don’t produce for at least a decade doesn’t change the short term world value of crude. As proof, the Interior Dept. under Biden is on pace to issue more drilling permits than his predecessor, and had a record Gulf lease sale last year. Yet here we are. Shut in wells opened by their operators might make a impact on local crude prices, but that’s a corporate decision based on the market value. As is the future production of crude from later sources like the Bakken Field.
Petroleum will be around for longer than many would like, but more for their use as feedstock for many product we use daily. As an energy source, it will continue to drop off. The rate will be dependent on us and not on multi-national companies, I hope.
I like to agree but the majority of gas station owners are moms and pops and individual small business owners, not corporate chains.
Every bit of the conveyor belt process adds cost. No greed here. The media does not cover every part, from surveying, loans, permits (so far 5-10 years of the process), transportation, refining (depends on how dirty the oil is), and more gov’t permits. At this point, having been told to reduce production and give permits that take 10 years to complete (on purpose) gives the go ahead to buy abroad. Which “just” happens to be Russia and OPEC with Iran and Venezuela. This is a plan and NOT by the Ukraine war… need someone to blame.
I would like to agree but can’t go along with a big lie to implement their green plan with no transition but to make us collateral damage.
Politics, and more specifically, policy, ABOLSUTELY has an impact on fuel prices. If existing or new oil & gas projects keep getting shut down or hindered, particularly pipeline capacity, through onerous government policies (see Keystone XL), and the world’s demand for oil & gas continues to increase anyways, you get supply constraints, which drives up demand, thereby increasing the price at the pump. And for all the oil that is still coming out of the ground, ridiculous corporate ESG policies being pushed on every single company out there by the hedge funds (think Blackrock) just makes everything way more expensive.
It’s simple supply and demand…basic economics.
I would recommend the Duramax. Diesels are the engines of choice in Europe, the birthplace of automobiles and the internal combustion engine. The Germans are much more savvy on engines and automobiles than Americans. Also, highway design being the first with the Autobahn. Which Eisenhower saw on his conquest of Europe and adapted to America. If you thoroughly understand the concept of diesels and their design they are superbly above gasoline engines. The commercial carrier industry with their choice of small, medium, and large diesels along with the makers of construction and mining equipment exclusively to power their trucks and machines will enforce my suggestion.
Just check out the price of Cummins, Inc. stock.
My brother in law has a 3.0 diesel that’s getting 19 mpg on the highway. He’s not a happy camper.
You’re right, not good. I’ve had four gas trucks, all 4×4 (two 5.3L and two 6.2L) and averaged lifetime 21.5 combined with the 5.3L and 20-ish with the 6.2L. I drive almost ideally for high fuel mileage. City driving was significantly worse with the 6.2L than 5.3L, highway was just about the same though. I’m back in the market for a 2022 Sierra (leaning toward Denali (not Ultimate)) and am struggling with the decision to go 3.0L or 6.2L. My brain says 3.0L and my heart says 6.2L. Towing mileage is also about the same with 5.3L versus 6.2L but the 5.3L struggles. Higher speeds on either drop mileage significantly.
What are the driving conditions for your brother-in-law?
Mostly Highway as he travels for work around the Country doing pipeline inspection. He was expecting high 28-30 on the highway. I read a couple of tests that said that. They must have been doing all downhill driving with those trucks. He said the Raptor he traded got better mileage then the GMC.
Coworker has 3.0L in AT4 and doesn’t drive hard but drive 5-10 over. He’s getting around 23-24. Oddly we all get better mileage around Denver with varying terrain than in plains states.
Maybe he should be an adult and hit cruise control instead of mashing the gas pedal like a little kid
My co worker and I both have 2021 AT4’s. We both drive/commute about 40 miles to work. Some traffic in morning and quite a bit in evenings. I have a 6.2 and drive it pretty hard. He has a diesel and also drives it pretty hard (meaning 76-80 instead of 65-70). He gets about 18-20 and I get about 16-17. Now, you also have to compare price per gallon. It ain’t the same. I run premium every third tank. Regular for the others. Truck runs very well on that system. Currently, we spend about the same. The 6.2 probably costs on avg about 10.00 per tank more or about 500/year on 20k miles. (3.85/G vs 4.35/G) today that disparity is more but I’m not going to compare using highest we’ve seen. Diesel is about 5/G but gas was 3.90. So, For about 1.50/day I’ll take the growl of the 6.2 all day long. All day! If anyone on here is “concerned” about fuel economy you’re on the wrong thread IMO.
I travel about 65 miles round trip in Houston, I average 19 mpg with the 5.3. In a year I would save over 308 gallons each year with the diesel at 29mpg . That’s about $1300 a years worth of fuel savings. It doesn’t take an idiot to realize slapping the truck in cruise control with Lane Assist at 65-67mph is not that horrible at all
I have 2021 Denali 3.0, round trip1900 mile vacation NY to HH average 24.7. No sweat traveling through mountains. Around town average 26. My 2017 Suburban never saw 20 on a trip and ran hard through mountains . Would never get a rid of the 3.0! If I stayed at 77 or under it would be higher
Autox. Wise choice.
Go baby Duramax. Sweet. Stay with the same oil brand and oil weight throughout the life of the engine. Highly recommend Mobil One synthetic 0 – 20. Safe and fun motoring to you and yours.
I love Diesels.
