For ReaL!  Seriously?  The best thing since sliced bread!

Yes, just plain yes. Want to hear about the new gas engine.

I just read through the GMC Life webpage for the AT4 version.  The Duramax is NOT listed as an engine option?!  For a 2500HD?  That's screwed!

That's not an unfamiliar concept.  You can't get a diesel in the Power Wagon either. 

 

As for why, I'm sure some engineer will tell you the diesels "don't meet their design criteria."  That could have something to do with weight, or perhaps cooling during high load, low speed off road crawling.

The AT4 is supposedly replacing the All Terrain & All Terrain X packages in the 2500 HD.  Well my All Terrain and an All Terrain X I almost bought instead both had Duramax in them. So that doesn't mesh. 

 

A lot of people I see out in the Arizona mountains (6,000 ft and up) hunting or 4 wheeling are driving diesels.  Diesels are great for rock crawling because of low end torque and the turbo for overcoming the altitude.  And a lot of those have hauled a large fifth wheel with them to camp with.  Not going to sell a lot of AT4's in that regard.

 

Hopefully GM will reconsider that option.

The one in the pictures looks to have a Duramax judging by the hood scoops and tailpipe.

^^ what he said... also, the page https://www.gmc.com/gmc-life/trucks/introducing-the-first-ever-2019-sierra-at4  Is referring to the 2019 1/2-ton.

Agreed, assuming they make it right.  I kinda wish they had stayed with All Terrain/All Terrain X.

Great find MrChips, thanks for sharing.  Just what I was looking for, first time I've seen any truck with that combination of badges.
