I will avoid engines with turbos as long as I can.

Yes I agree they can handle it but would 600 hp and 8-900 ft/lbs in the half tons survive the durability testing? There wouldn't be a point of the 2500/3500 trucks once you boost the v8's...the engine is a rockstar (minus the dfm stuff) and it can handle the power but can the transmission, driveline, axles, brakes etc? They still need to keep the two segments of half tons and the super duty stuff. And we consumers need the lighter duty better mileage options also.

I do see the shift away from NA V8's though and once you boost you don't need that many cylinders anymore so it's going to be 4's and 6's. There will be a need for the base engines and high power engines...just as we've always had but gm is early to the game with one helluva a base engine which looks to make the 5.3 irrelevant so they need a boosted 6 to do the same to the 6.2 and surely it will be coming. Then one good diesel option and you're all set for your half ton motors. The average guy motor, the Tim the toolman Taylor motor for those who eat their wheaties, and the diesel....all of them will be boosted.

We have to keep in mind the masses not the enthusiasts in these discussions, plus the durability testing that the manufacturers need things to pass so they know they don't release a dud to market.

The masses are probably rethinking large truck and SUVs purchases with these gas prices. I was driving my 92 Chevy 383 whipple powered 12 mpg truck happily just two years ago. I owned it 12 years just doing maintenance. I’m a lead foot. In contrast I’m mostly driving an CRV. My current 15 mpg Avalanche is currently driven once a month. I’m always going to have a V-8 around. The V-8 sound is a nice antidote to what being forced on us now. A drug I’m unwilling to live without.

Well if I hadn't had the experience I did when younger with the early dodge cummins trucks then I would be with you, and in all reality I am with you except that gm basically built a small gas cummins and it could be a game changer.

I like things designed to last, and grunt, but not drink like it's at an open bar, and this is the first gas engine to come along that appears to have that formula.

It's had 3 years to prove itself and it's done well enough that gm has gone all in as base motor and upped the power rating. Not hearing any flies on it. So if you're forced to go boost one day...gm may have you covered with the best of the options. They already got me covered as that's far more grunt than I need, shouldn't work hard for me and my needs, live at 4000' and pull 3000 lb trailer for fun stuff.

well with more than one vehicle then you can afford those choices, I used to get that drug from v-twin motorbike on the side, when I got my manual gladiator I did intake/exhaust so I could hear/feel shifting etc. and had so much fun again I sold the bike and put in couple thousand watts of boom boom into the jeep as trade off and didn't regret it one minute, that's a unicorn vehicle aside from the dang engine that shat the bed at 78,000 kms (saga ongoing)

as a single vehicle only for this single dad so my ride has to be the mini-van, grocery getter, and hunting and fishing vacation machine also, the kids will be driving soon so those will be the cars added to the fleet taking up space on the street, I'll need to remain one vehicle only that has to be as versatile as possible

I've been watching, dreaming of a 4bt like power plant that's modern and emissions friendly with all those simple attributes and contemplated building one and dropping into the gladiator but there's just too much involved there and likely wouldn't pass any inspection lol. This gm 2.7t is perfect other than I can't get a manual transmission...I'd about die if I could...absolute dream truck right there with that motor and a stick. Would give me everything I loved about those gen 1 cummins in a modern lightweight efficient clean gas package.

My wife has two, I have two. The newest is 7 years old. If I only had one it would be the Avalanche

I say this acknowledging I may be 100% wrong, but I have a hard time seeing the gas engine last in a gm vehicle past 2030 outside of super duties. I say this because if they were committed to the tech, they would have, imo, retried hybrid first before all ev. I think even Mary has stated much. Heck, Ford has a full hybrid and dodge has a mild hybrid. Again, I could be completely wrong. It just reads to me, given some of the comments they have made publicly, ice is dead.

ooh, this looks like it could be a dandy derail, who's Mary and who said publicly what? and ice is dead? Is that meant to reference global warming?

I'm down if you are...gas and diesel are here to stay, especially in 4wd things that go remote and once we get over the lies on climate and 'Dino juice' it will be easy to see, most of these 'new directions' are manufactured so certain pals can make more money, they get all the patents lined up years in advance and get the contracts ready to pass around to their pals and then create the narrative to start the money train, free electricity will be coming since it's all around us and has been tried to offer to us before but the money hungry wouldn't let happen and for a bulk of transport it will be used but the 4wd peeps who get far away from civilizations we will still always have gas, at least until they can squeeze an equal amount of energy into a battery for similar size and weight to gas in a gerry can then maybe we can get away from the second most common constantly regenerating fluid found on earth(oil), I say this acknowledging that everything we once thought to be true may 100% be wrong as we watch the veil of this grand scale deception being lifted on the daily, but really lifted the past 2 1/2 years.

committed to the tech? 33 years ago a 5.9 liter cummins did 160 hp and 400 ft/lbs torque and was, still is, one of the most desirable engines, the new gm 2.7 liter does 310 hp and 430 ft/lbs, the first one a 1200 lb motor so had to be in 3/4 & 1 tons..the 2.7 is about 375 lbs and can fit in half tons and mid-size trucks and even cars...sounds pretty committed to tech to me, makes a lot more sense when we know the truth about oil, not Rockefeller's made up narrative about it

Derail how? They are designing now for 2028 and beyond. So by making comments about 2035 being pure EV indicates the brand doesn't want ice anymore.

Personally, I believe it is stupid and cutting off one's nose to spite their face. But this is the new gm. But whatever. I'm not sure what you thought I was getting at, but by the companies public stance, and as I stated, I could be wrong, they don't seem to value ice anymore.

OnTheReel · June 13, 2022

Not making excuses for GM since they were heading down this path for years before. But now they are really getting their arm twisted by these ridiculous new CAFE standards, and of course the fuel prices under the Brandon admin.

The plan has always been EV, by force. And if the public still rejects them, I predict government bailouts for GM, and a golden parachute for Mary Barra.

John813 · June 13, 2022

Turbos and less cylinders is the future for ICE, with some hybrid tech at some point this decade IMO before the full switch to EV. With maybe Chevy maybe going straight to EV skipping the hybrid tech

Ford beat everyone to the V6TT party and is one step ahead with the powerboost.

Although through my real world testing there is no real MPG savings between a 5.7L Hemi Wagoneer vs a 3.5L Expedition with close to the same gear ratio (3.21 8 speed Jeep vs 3.31 10 speed ford). 17.3MPG vs 17.6MPG

The only ecoboost full size I saw noticeable MPG improvement from was the 2.7LTT, which is a very good engine. Honestly would have zero complaints using it as a DD. Got over 23mpg driving a 2.7LTT 5 years ago as a 2 month loaner lol.

No doubt in my mind Chevy will release a 3.XLTT engine that will kill off the 5.3L and possibly the 6.2 shortly after in a few years.

Ford still has the 5.0, which has yet to get much R&D compared to the ecoboost in the trucks.

Seems like Ram has rung the death bells on the 5.7L in the 1500's with the Wagoneer going 3.0LTT in both lineups.

But the wagoneer MPG barely moved going from the 5.7./6.4 to the equivalent 3.0 engines, but they'll get boatloads of more torque.

Its a form of Cash for Clunkers 2.0 with this EV push at the expense of the people as usual (gas prices). I'm all for EVs existing, but its being done all wrong and too fast. There needs to be a coexisting period of new ICE and EV to ensure that the rest of the US infrastucture can be rebuilt to handle mass EV charging. People keep saying "charge at night when the grid is low!". That's great, until the grid can't handle that even.

At the rate the automakers are going, there will be shortcuts made on battery packs, motors and other controlling electronics, with recalls and possibly worse to follow. The Ultium tech that GM JUST launched already has a Gen 2 that's not far behind it.

The Powerboost was a great move on Ford's part. I watched a couple of TFL's videos on it as Andre has an F150 Powerboost.

To be fair on the Jeep, the Grand Wagoneer is 6400-6500lbs, not exactly light. They went from 13mpg city to 14mpg city, 18mpg to 20mpg highway and from 15mpg combined to 17mpg combined, and those ratings are with the HO 3.0TT so 500hp. When viewed that way, the "small" gains are of a descent size considering its heft and the big power bump.

For whatever reason Stellantis/FCA seems to not use alot of composites or aluminum? If they can only step up their weight loss game, it would help them immensely with fuel economy.
