Anyone got any scoop on the 2027 GMC trucks? Supposed to be fairly major changes in and out. Look like they'll start production in October with November/December deliveries. Love the Denali Ultimates. although ii don't like to buy newly designed engines in the first year \ of production like the new 6.6. Would lean the 6/turbo diesel for my needs. Rumors are they are vastly improved in appearance at the least.

Can’t hide money.
They are taking orders but no pricing has been released yet. Still tight lipped on power numbers for the new motors...this close to production that's a little strange. I think the Silverado looks better than the Sierra which looks too much like the electric vehicle version in my opinion.
Still have active fuel management? Still sitting on the lot if they want me to buy one.
I’d wait a couple of years before buying any newly designed vehicles. Maybe they’re backing off the insane attempts to get another 0.1 MPG at the cost of reliability. But I need to see it to believe it.
I had the 6.2 in a 2024 model. Took it in to the service dept due to the engine recall. They ran the test and said it was fine. Three weeks later it bugged out. I replaced it with a 26 model. I'm intrigued by the new models mostly for the bigger engines and the interior upgrades, but GM is notorious for having issues in the first year of material drivetrain changes. And I say that as a GM fan; I won't drive anything else. So I will keep what I have until 28/29.
I would seriously wait at least one year before buying the new models. They have a ton of new tec and GM has a track record for having a lot of bugs. Talking with the dealer they estimate the 27s will be around 3-5 thousand more than the 26s at a minimum and the ultimate could be 5-7 more.
If you are in the market the incentives on a 2026 are hard to pass up right now. The 3.0L duramax is a solid motor, tows like a champ and sips fuel for daily driving. I bought a 26 with the baby max and I love that motor but with the cost of diesel rising faster than the price of gas it's like a kick to the nuts when you fill up.

Yeah spending 150+ at least twice a week every time I fill up sucks right now.
This will be a mistake. My HD had the Allison and my motorhome has an Allison. In my experience it’s a good transmission.
And the new tanks I believe are 34-35 gallons as well but it sure would be awesome to get 1000 miles per tank.

NEVER buy anything major the first year of big changes. And don't buy it the second year if you can help it because then they may have big changes to fix the issues from the first year.
I will say that with my 5.3 gas burner I was filling up twice a week typically on Monday and Fridays. Now with my baby max I fill up once a week on Mondays.
What about 1000 mole crickets per tank?
There is absolutely some truth to this but having worked in the automotive arena for a few years I can also tell you that I've seen instances where parts, etc. were "over engineered" initially only for them to come back and make changes in subsequent years to save money.
If you do buy a Denali Ultimate, sit in one first and pay attention to seat comfort. My cousin did not. Traded 10 days after purchase for an F150.
The Dodge Ramcharger EREV is what I'm waiting for.

Scary thing about the 6.2 engines. People who have had GM replace their engine with a new one with the problem supposedly fixed are having the problem recur in the new engines.
Yea, i've seen those range AFM disablers you just plug in under the steering column but also heard those are just a slight fix and you can still have lifter failure unless you actually go in and replace lifters, and cams. My mechanic said he could do it but was like $6-7k I think.
I've got a '25 Yukon with the 6.2. My father in law had a '24 Sierra with the 6.2 that blew up on him at 24k miles. He said that the possible tie-in to the active fuel management system is that it deactivates some cylinders at highway speeds, but when you step on the gas and they get reactivated, the lubrication couldn't quite get there fast enough, and this occasional momentary dry-humping added up over time. But who knows - I've read other things blaming it on a bunch of other issues.
Assuming my '25 holds out long enough, I might replace it with a Yukon with the 6.6 when the update makes its way from Sierras to the Yukons. The interiors of the new Sierras do look pretty nice, and those updates usually make it to the Yukon the following year.
The GMC site has a page set up for it so you can see what they look like. Mash here: https://www.gmc.com/future-vehicles/2027-next-generation-sierra-1500
Honda has had a similar debacle they call VCM (variable cylinder management) for their 6 cylinder engines. I disabled the VCM on my wife's Pilot with a $100 part I bought on line but I am sure the late model GM V8's would be much more complicated if not impossible to disable . Also when I disabled the damn thing the car's performance and gas mileage improved .
I'm not sure even GM really knows what the issue is. But fuel management is pretty much the cause for most all of the engine problems we're seeing across many manufacturers.
Denali is the most overrated package on a truck ever. There is nothing different other than the logos.
Crazy to me that Cadillac came out with the 8-6-4 engines in what, late 70s/early 80s? And everybody's still apparently struggling to make something like this work.
It's almost as if continually stopping and starting an engine cylinder inherently puts the cylinder under a lot of unnecessary stress.
I sort of soured on GM products after a brand new company dually I drove......transmission went Kaaaput!! After about 10K miles on it, the trans started whirring and then failed altogether at about 20K miles. I then stuck with Ford-150's and Dodge Rams.
The lifters that are the root of the problem is still in the engine even if you disable.
My last 3 trucks were Rams and I've always been very pleased with everything about them. But a good friend was the dealer and took really good care of me throughout the past years. I haven't personally shopped for a vehicle since 2017...He would let me know me when he had what he knew I liked and I drove to the dealership, left mine and drove off in another one. BUT, he sold his dealership so i've lost that hookup. So now I'm shopping - haven't ruled out Ram, GMC or Ford. Just don't know all that much about any of them. This thread helps immensely. The pack always delivers.
They actually extended the powertrain warranty on that engine to 150,000 miles. When I took mine in they said it was going to be two weeks before they could even look at it because they had 7 other trucks on racks getting engines replaced. This was at Sunrise GMC in Collierville, TN.
Brother in law did the same. He waited about a month before doing it. There was more than the seat that he didn't like though
The guy at the dealership told me that GM used cheap materials to manufacture the lifters and that was really the problem.
The CAFE standards now have $0 penalties associated with them, so there is not the same incentive to do stupid stuff to satisfy politicians. And they are rolling back the standards even after eliminating the penalty, which I guess is helpful but presumably any statute that restarts the penalties will also up CAFE standards again.
