Anyone waiting for the next gen V8s?

[MichaelSE]

Never thought I'd get the itch for another 1500 after I sold my old one, but I love the idea of having a 6.6L 475hp/500ft-lb engine in a new Suburban with all the tech. If the next gen SUVs look good, and have good pricing incentives, I may be in the market.

I know it's generally not advised to get the first year of a new generation, but I figure by the time the next gen Tahoe/Suburban comes out, the 5.7 and 6.6 V8s will have been out for a year or two in the Silverado. Hopefully GM has lessons learned from AFM/DOD failures. I understand these new engines will have a similar type of system, but it will be more robust.

What are your thoughts?

The Tahoe/Suburban were refreshed in 2025. Realistically, I wouldnt expect a full redesign until 2029 at the earliest.

You are correct in your though that the engines being introduced into the sierras will help them iron out some of the issues, however I would still wait atleast a year for any of the technology glitches.

So basically if youre willing and able to wait till 2030-ish, then it will be great!

It wouldn't wait for something that may or may not be a thing. But then I would get another 6.2 in a heartbeat. I think the 3 engine choices in the big SUV are fine and would have not trouble with getting any of the 3.

Good point, didn't think of the refresh. I guess I viewed that as more of a facelift of the T1xx. But 2029 is realistic. The SUVs are updated 2 years after the pickups traditionally, it seems.

I suppose I can wait until 2030.. gives me more time to save money, since the base price of an LT will probably be >$70k at that point!

I am waiting for a solution to the problems with the engines, so I put up for sale my Yukon with a mileage of 180 thousand km

It looks like the DOD system was redesigned. The activation/deactivation point was moved from the lifter itself to a common rocker shaft system.

From the description it looks somewhat similar in theory to how the 2.5 and 2.7 are doing DOD. (no known issues in this platform.)

Chevrolet can build a reliable engine if they simply stop forcing that DOD, AFM garbage down our throats. They can redesign that until the end of time and it will remain as garbage. If DOD was an option, who would buy it? The fuel savings will never cover the cost of the damage caused by that foolishness!

GM doesn't want DOD/AFM any more than we do, they are forced to use it to avoid EPA penalties on every engine they sell

The EPA is easing up on these requirements so making engines that consumers want will hopefully be possible again soon

These 'features' are due to government force, going back more than 50 years. No car builder enjoys alienating customers.

And this easing will probably be re-reversed when the blue team gets control again.

All the more reason to buy one as soon as they are available

But I suspect it will be much harder to return to the cursed state we are in now after everyone gets a taste of good vehicles, reliable appliances & affordable energy

We got here slow like the boiling frog so many never knew how awesome it was back when manufacturers were all competing to make stuff their customers wanted; not sure a quick reversal would be possible once people see what that's like

I currently have a 2019 Tahoe with the 6.2, and 78k. I have not had a single engine related issue, (the magna ride shocks and air ride suspension are another issue). I used to work at GM and not even GM employees would buy a first-year product. But it's time for a new one. So, I'll be ordering a 2027 Yukon later this fall. No thank you to 2028-2030 models.

I wonder and worry about companies that don't spend the money taking advantage of the eased regs because they're afraid of the expense caused by the rules being reimposed.

On our 3rd 3.0L Duramax. Highly recommend. Amazing fuel mileage and a $1500 credit for the engine on the Denali Trim. Fuel is about a wash since you’re recommended Premium on the 6.2L.

 

[fondupot]

I'll be interested...in maybe 2030. But my company truck will get to experience them sooner when we swap out an aging 2022 Silverado, probably mid-2027. It'll be a 5.7L. So I'll get to experience that before it comes to the SUV's.

I would get the new engine if I happened to need a new vehicle at the time, but, if possible I would avoid the first few years. So we're looking now at what, 2030? It's not coming out 2027 in the SUVs from what I saw.

I saw a comment in the OP's post--"good pricing incentives." That's impossible. A 2026 over a 2025 HC is almost $5k more, essentially the same vehicle. Most people I know, their salaries may be large, but they are not increasing at the rate of everything around them. Those who got a 2026, I get that you bit the bullet, but $5k isn't nothing. You have to feel some pain. One friend got a 43% raise (machinist), and he complains about inflation like everyone else. He did get a new 2025 Escalade though when the raise was official lol

I do and I don't understand how come it's so easy to pull the wool over consumers' eyes nowadays. Anyway, it's no different than 10 years ago imho, where, if you don't need a new vehicle, feel glad and don't buy a vehicle. One is not going to beat the mfg nor the dealer, they can discount a 2026 $15,000, and it's not a good deal versus 20 years ago. There is no good deal today lol 3X over the 2025 model year there were price increases, and it was as if buyers were oblivious. There were even people here who said there wasn't an increase, which is mind boggling. They claim a Honda Pilot is almost the same size as a Tahoe lol

This wasn't always the case, buyers became quite savvy when the internet came around and stayed such for 20 years. Dealers got routinely beat up--they never lost money, but their margins were uncomfortable. Now it's changed. At any rate as far as a new V8 goes, I would avoid the first year, which apparently is not 2027 for Tahoe/Suburban, and wouldn't worry about it unless I happened to need a vehicle.

Lastly the sum total of a lot I've seen online, 2000-2014 generally speaking was the golden era of car mfg. If you have a decent vehicle in this age range, good chance you should keep it and repair it. my .02 ymmv
