GM better come up with something better than their current engine lineups

[Plato442]

GM will start turbo charging their engines as well. They dropped the new Vette engine after what, one or two short years…I’m sure they’ve tested turbs and will make the switch soon

As I recently explained to our ex-SIL who was buying a twin-turbo Ford F-150, a turbocharger requires owner-understanding that like a set of brakes, a turbo will eventually wear-out and fail. You can extend their life by using only top-rated synthetic oil like Amsoil's Signature series and changing it more frequently but turbo wear and tear occurs at time of shut-down when they are still spinning and very hot and all of sudden the oil-supply stops and oil "coking" occurs. Having owned a Y2K F-350 with the older 7.3 Powerstroke and putting over 500K on it over 12 years I acquired a lot of knowledge about care and feeding of one large turbo and very early in the first month of ownership installed an ISSPRO turbo-temp monitor thermocouple in the downpipe that prevented fuel shutoff until the thermocouple in the downpipe said it had cooled to less than 300 F. Manufacturers are now trying to convince turbo engine owners, that have enough understanding to inquire, that thermal convection will continue to move the coolant past the turbo to sufficiently cool it after engine shut off.....LMAO ! All this is ignoring the introduction of oil vapors from the PCV system into the multiple intercooler and pressurized intake hoses that can lead to blow-off of said hoses from their metal mounting surfaces. There's a definite reason Ford tech's ( one of my best and closest friends happens to have been one at a very large Dealer before he went to Mercedes) will opt, like Bill 1960 posted, for the V-8's on their personal vehicles.

true the turbo needs to cool-off first before being shut down (each time) which is inconvenient for a daily driver, if one had a alarm system installed like I have in my vehicles you could just press a button, take the key out, lock it and walk away and it will automatically shut off after 10 minutes.

The ten year plan from our noble comrades of the revolution in the federal government is to be done with internal combustion by 2030. That's less than 10 years.
I'm not happy about this but there's less than zero we can do about it.
Why should they spend development dollars on new more efficient internal combustion engines when they're getting the gift of electric vehicles by government decree?

a lot of oems also water cool turbos, which they continue to circulate coolant (electric pumps) after shutting down

I remember when GM redesigned the sbc and came up with the LS, all of the reviewers laughed at the "obsolete pushrod design" that was so inferior to all of the overhead cam offerings from Ford and the foreign manufacturers.

Of course that LS engine and all of its iterations has proved to be the king of the road for everything from SUV's & pickups to some of the fastest performance cars ever built; with reliability to 300 k plus they are transplanted into everything imaginable today.

So now the claim is that tiny turbo motirs, hybrid or electric will somehow knock these workhorses out of favor as poor obsolete GM keeps offering those clunky pushrod engines.

GM has owned the workhorse V8 market since 1955 despite multiple predictions that their demise is imminent, I wouldn't hold my breath waiting for that to materialize.

The SBC came out in 55' as a 265/283 and in 97' the LS came out. Now the LT with its Direct Inject has basically taken the ICE about as far as it can in its NA form without putting $ 1000's into turbos etc.

Our Hammer and Sickle Greenies want us to collect cow farts and live off the land...oops thats not VEGAN....

I have nothing valuable to add to the conversation regarding engines. But Idc what engine they put in a Sequoia, it's still ugly as sin and a no for me.

Huh the 2023 has not even been released yet. How do you know it is ugly as sin? LOL

I think we can all agree that GM no longer gives a rats ass about their V8s and the quality of these engines. If that was the case this design flaw that is bending push rods left and right on the 5.3 and 6.2 engines would have been solved a long time ago. GM's focus now is making the tree hugging lefties happy with EVs and putting all their eggs in one basket. Until GM does a voluntary recall on this lifter/push rod issue I'll take my money to other brands. just hoping my 2021 lemon Tahoe can hold together another year or so. I have never had a vehicle be in a dealership as much as this pos and I have owned more than 40+ vehicles. Pretty sad this day and age that their quality is heading south

 

[avalonandl]

I am in full disagreement on your statement. I think the bad parts are due to poor QA and cost cutting. Not due to focus. GM needs these engines at the most profitable plants they have. That and 3$ will get u a coffee at some coffee shops. Not pikin a fight, just giving u my opinion.

 

[gooffeyguy]

The reason I've intentionally NEVER purchased a first year of a new or generation change vehicle. I wait a year or two for the bugs to get worked out.

Kind of like being a beta tester, but you don't get the vehicle for free, lol.

I do appreciate everyone that does though. I appreciate the time spent and headaches having to deal with all the problems so future models will be hassle free

Thats ture, but they've always been ugly, so I'm not holding my breath. Something about lipstick on a pig..

I wonder what GM is going too do in the future too compete with Toyota. On September 19th Toyota introduced the new engines that will be in the new Tundra and most likely the newly redesigned 2023 Toyota Sequoia that gets introduced later this year. Toyota is going away from V8 engines and are going too offer two 3.5 liter twin turbo V6 engines. The I-Force max has an electric motor sandwiched between the engine and transmission. The base 3.5 twin turbo I-Force engine pumps out 389hp with 479lb-ft of torque. The I-Force Max hybrid engine jumps those numbers up to an amazing 437hp and 583 lb-ft of torque. They can tow of to 12,000 pounds!!!!! I was going too order a 2022 Tahoe with the 3.0 diesel too replace our current 2021 Tahoe with the 5.3 that we Lemon lawed but they put the 3.0 diesel on hold until the end of the year. We are also replacing our 2013 Honda Pilot with a diesel Suburban or Yukon XL next summer. After having seen the numbers on these engines from Toyota it looks like my wife and I will be getting his and hers Toyota Sequoias View attachment 351339 LOL. Their engines have diesel torque numbers along with great MPG capability and 0-60 numbers that should be sub 6 seconds with the I-Force max engine. I'll be interested too see if GM is going too counter with a Turbo V6 and or hybrid option soon. Lets face it a 5.3 v8 and 6.2 v8 with a DFM system is way behind the times now. An all electric large SUV won't work for our family because we take long trips and tow stuff. Come on GM get with the times!!!!!!!! https://www.toyota.com/upcoming-vehicles/tundra/

I dont like turbos. Sure they make a lot of power but i dont like reving them that high to get there.

 

[TollKeeper]

Boost is severely addicting if done right thou..

Oh yeah...

 

[MichaelSE]

All I have to add is that I'm surprised Toyota is keeping the Sequoia around. I truly thought they would axe it due to extremely low sales.

It's probably a loss leader, it's their Suburban and is really more of a 2500 like yours than a 1500. It has high axle ratings and tow ratings and low cargo capacity. Despite the numbers, the GM trucks are far more useful and capable when it comes to towing.

That walking away with the key removed and the doors locked is exactly what the ISSPRO Turbo Temp monitor permitted doing. The propaganda the Manufacturers want you to believe that "Thermal Convection" will cool the turbo after shut-down is pure rubbish and, sadly, many owners will discover this the hard $$$ way.

I dunno. I've had four Japanese cars among my GM's and I didn't keep them long. They worked, but I did not like them at all. They were mushy or they were tinny and all were homely. I did not enjoy driving or owning them, more like appliances than cars. My Dad had a Lexus once and was really sorry he bought it and went back to GM after a year of Lexus leaks and failures - almost as bad as a German car. I think the reputation of Japanese cars has more to do with America hating Ralph Nader than the quality of the cars. When it comes to standing up to hard use, collision survival, usefulness, styling, value for the money, American cars are generally best.

 

[CMoore711]

Well... Looks like GM came up with something.

Just released a couple days ago:

Chevy Has a New 10-Liter Crate Motor That Makes 1004 HP

A naturally aspirated engine with that much power and 876 lb-ft of torque on pump gas proves that we're in the midst of a golden age.

Wait... Were we talking about specifically coming out with something electric, boosted, and/or more efficient on gas?!?!? Nevermind...
