It says a lot that you guys consistently sit down and have these conversations, and the guests are consistently like "...yep." (your research is solid). No one does this kind of content, love this channel. I think the guests gain an appreciation too (respect of craft).
Completely disagree. In a vacuum, yes the engineer segments are fine although I never found them that great to begin with. They are just gonna toe the company line maybe with some good nuggets here and there. Jack can cover most of it.
If you watched the last livestream, the future of this channel seemed in serious jeopardy due to burnout. Reduce effort and cut these out.
Would you rather have engineer segments or no more SG?
@@austinfrazier7325Man, are you with Deloitte or something?
@@toddlehman1 don’t even know what that means 😂
@@austinfrazier7325 Whatever they decide to do with this channel, I will stick around for it to try. The decision you pose is not my responsibility, but theirs. Like many RUclipsrs, they will have to weigh the tough choice of time/effort vs retention, and I won't fault them for changing directions.
edit: Because you could very well be completely correct
They are what they are because of in depth stuff like this. If we wanted the same old reviews, I’d check out the other 12,000 car review channels. Keep it up SG
Props to GM for consistently supporting SG in these kinds of videos. Well done to Jack too with the interview portion. He structured the interview really well and asked all the right questions. Maybe in the future we could get full interviews on a Patreon?
Yes for sure. Its planned for CX90 and Lucid
@@savagegeese Thanks for taking the time. I'll be there
I'd rather have a strait 6, but they don't work with modern truck short hood design.
I work at the Wentzville Gm plant that builds the Canyon and Colorado, thank you for the great review we are proud of what we build.
Thank you for my 2017 ZR2! 112k on the clock and she is still perfect
Actually, thank you. I want to the Trail Boss that bad!!!❤️
Correct me if I'm wrong, but I don't think there's been an engine with cylinder deactivation that has turned out well in the long run. At worst they're regarded as some of the shortest lived engines.
Corvette C7?
Mazda 3?
Agree and coming from gm and their shitty history of 4 cylinders nd deactivation
Agreed, and that’s why the after market offers DOD delete kits.
My 5.3 is from 2009 with AFM and so far it has held up. I do know the dark side of AFM though bc my dad had a 2008 Avalanche with the same powertrain and he had lots of top end issues all related to AFM. It seems to me that they last about 150k before major issues occur, or they have issues immediately. You can deactivate or trick the system into never triggering AFM but that requires a tune or a plugin from one company for $300. You can also replace the lifters with one piece lifters and a tune and that will make the truck run like it was designed without AFM in the first place
Full disclosure. In my 23 years working in the Auto Industry. 11 of them have been with GM. I started in 1999 took a long break and back since 2014. Ive seen the worst and best of GM. This engine seems to be well built. Ive driven many since they came out in 2019. Including a loaner for a week while my Silverado Trailboss was down with a transmission issue ( 8 speed, internal temp sensor failure). They drive well, they build boost fast. However, i vert much disagree about then sound, these sound awful! Im general i enjoy the sound of a properly boosted 4 cylinder, I grew up modding DSMs. But the 2.7 sounds like it hates to rev.
Fuel economy. My 5.3L Trailboss get better highway fuel economy than a 2.7L without the Trailboss lift and highway tires. The 2.7L is better in the city for sure.
Overall the 2.7L is a fine choice. But it's not better than the 5.3L
Yeah they are approximately equal depending on your needs. It would be awesome if they made a turbo V6 mild or full hybrid (not plug in) to give 20mpg+ in the city
It seems like the primary goal of this engine was not to be "better than the old 5.3L V8". Seems like it was mainly to develop such a modular engine that they can use it in a bunch of different applications and vehicles. Being sort of "equal to the old 5.3L V8", better than the tragic 3.6L V6, better than the 2.5L 4cyl, and being able to scale much more production of just one engine seems like a win for the brand overall, as long as they prove reliable. I don't know if I'd particularly want this over a 5.3L, but I'd definitely want it over any of the prior 3 Colorado engines.
Lmfao whatever man
How many Transmission is going to take to know you have low quality 😂
Time will tell. Most new engine designs start out on a positive note but most do not fare well in the long run..
Man I can’t wait to see a comparison of the Colorado and Tacoma
This is going to be interesting for 4 cylinder trucks
The biggest problem I see is that they're probably not going to last over 150k miles before needing a new engine. Whereas a good 8 cylinder will last over 300k.
@@user-re6yj7gr6j Good point ig time will tell
I will not own a newer toyota tacoma with the 2GR-FKS v-6 engine. has DI and Port injectors. Port alone is perfectly fine to go with. DI has too many problems.
@@user-re6yj7gr6jYou don't know that though. The same crap was said when Ford came out with the 3.5 Ecoboost. Those engines have evolved and proven themselves.
GM can't afford to screw this engine up. My money is on this engine being a durable workhorse.
@@user-re6yj7gr6jI’m sure they’ll be fine, they’re pretty big for a 4 cylinder
Much respect for that interview. I don't even have an interest in trucks but hearing what they had to say about their engineering of this product made me respect GM and their engineer teams just a little bit more now. Jack kept digging for more details and info and we all got rewarded for it. Great review, this is exactly why this is my favorite RUclips automotive channel by far.
It will be interesting to see how all these new, turbo 4 cylinder truck engines hold up over the long run. This kind of engine seems appropriate for a mid size truck, but I'd personally rather have a V6. Great content from Savage Geese as always!
I agree. Give me a NA v6 anyday.
They have been out since 2019. No major issues so far.
@@terrencejones9817 I just want less wastegates and mechanisms to fail. I'll probably keep my tacoma v6 for a long time since toyota ruined the new one with a turbo as well.
Turbo replacements before 100k miles guarantee it all these new engines have even worse planned obsolescence than anything we’ve had previously. Manufacturers need to post earnings every quarter
They aren't designed to hold up over the 'long run'. The entire car industry is going 4 cyl turbo because they want you to buy a new vehicle out of warranty when they start to fail.
GM Jack did a great job of condensing lots of information.
The man wears 2 hats: GM and B58. Today was GM hat day.
@@r1ckz0mb0did someone say b58?
I know Jack was resisting the urge to mention the B58 to the engineer
God I'm experiencing hair loss just thinking about a B58 Colorado and Silverado
Please explain
I really appreciate the thought that went into this new engine and the journalism that made all of this information available to us, John Q Public. That said, I'd be a lot more excited for an inline 6, perhaps running lower boost levels than the I4, especially as a base engine in the Silverado/Sierra. Interesting that they went to the trouble to have an electric aux pump for pre-charging the transmission but didn't take that step on the engine and get oil to the turbo bearings, mains/rods, and top end before the engine even turns over.
That would make an engine last forever! Bad for business.
@@akdomun you know, I don't think it would matter much. Hardly anybody replaces a car because it has mechanically worn out. I think they'll trade out/up every 4- 7 years (or whenever the warranty is up) regardless.
@GoFastGator CLEARLY YOUR AVOIDING AN ENTIRE SEGMENT OF THE MARKET WITH THOSE REMARKS..LOW INCOME PEOPLE HAVE VEHICLES WEAR OUT FROM OLD AGE..MY BUDDY HAS A DEALERSHIP OF PRE OWNED AND JUST TALK TO A GUY LIKE THAT AND YOULL HEAR ALL ABOUT IT. IF A CAR BECOMES MORE EXPENSIVE TO FIX THAN WHAT ITS WORTH, ITS "WORN OUT"..WITH ALL OF THE ELECTRICAL COMPONENTS AND INCREASED COMPLEXITY THIS IS HAPPENING MORE NOW THAN EVER JUST LOOK AT THE GERMAN ENGINEERED STUFF IN JUNK YARDS.
Direct Injection and variable displacement are old problems for GM. The new ones are electric water pump, variable displacement oil pump and apparently electric transmission pumps. Great content, nobody does this kinda depth, just wish Jack gone deaper since he was already so far down the tech rabit hole.
All those plastic manifolds etc on cars start to crack and warp as plastic degrades with heat .
I really cannot believe they went with an electronic water pump. After decades of issues with BMW, VW and others have had with them, GM getting in this late to the game is just baffling. They even use PLASTIC! They'll be scheduled, early, preventative maintenance without a doubt.
Planned obsolescence… keep your old car for as long as you can. Even the globally-beloved Toyota will make their newer cars break more often than older ones. Most new cars are a scam.
Lexus IS500, for example, is probably one of the last new cars where reliability is truly guaranteed since it’s technically so old.
@@faheemabbas3965 Nailed. Smacks of it. New vehicles are Iphones. When they start to break and engineers who design them know when that is based upon development testing, you either dump the truck out of warranty or pay for it twice when things start to break and they will break like clockwork after 4 year warranty.
AFM on a 4 cylinder really? Is GM that desperate for CAFE?...that they will compromise engine durability by shutting off the inner cylinders at cruise? Direct injection = dirty valves no matter what the architecture. Electric fuel pump. Industry is going 4 cylinder to lower fuel consumption, increase engine temps and pressure, everything made of out plastic aka BMW and will fail at higher mileage. Planned obsolescence.
@lukewalker1051 don't worry about DI, they've got an overengineered PCV system and an intake port that generates tornado of air over the valve that'll just blow the oil right off 😂😂 give me a break. Even with a catch can its a matter of WHEN, not IF carbon builds up on the valve
Initially, I wasn't a big fan of large displacement 4 cylinder engines and I wasn't expecting much from the 2.7T used here either. I thought it was just a big cheap 4 cylinder for compliance and EPA ratings. However, listening to the GM guy talk about all the engineering and development that went into all aspects of this engine really changed my mind. Since the engine was designed this way from the beginning, it is likely going to be better than other engines that simply added a turbo to them. Add in small details like the electric water pump to cool the turbo even after you turn the vehicle off, and it seems like they really did work to not only maximize what they can get out of the engine, but also try to keep things as reliable as possible.
Just curious, what are some examples of other engines that "simply added a turbo"?
Yea good luck with that you'll still have pvc problems 😂
@@GoldenCroc I meant more in terms of how it used to be done. Although, the SkyActiv 2.5L engines from Mazda could likely still be an example of this.
@@cormaro13 It's PCV, but it looks like they addressed that in this new engine (we'll have to see how it works long term though).
@@GoldenCrocford 3.5 eco boost motor. The 2.7 v6 is so much better made because it was made for boost. The 3.5 had boost added later which exasperated components that weren’t made for that.
Dude seems knowledgeable and he’s rockin’ a classic SKX009….!
If this truck is as reliable as his watch they may have a new customer:)
Kind of interesting he made the case for how important oiling is for a turbo motor, and the took off the piston oil sprayers off of the work truck motor. I know there is a reason for it, but it doesn't seem like an area where I would make a cost cutting decision.
My guess is that the oil squirters are more for cooling than lubrication. Since the WT is lower power it doesn't run as hot?
Also they mentioned they had to pass emissions. As the oil sprayers increases fuel consumptions.
@@v8_sami They said they increase emissions. Dunno how fuel consumption would be affected, but to me it sounded like a thinly veiled hint that spraying oil there might increase the amount burned. And burned oil really does mess up emissions.
@@tom30 I was thinking that could be the case. However (I am not an automotive engineer), I remember older redblock Volvo engines with oil squirters (I think 1993+) usually experience a lot less piston slap as they age compared to older engines without them. I think most turbo redblocks always had them. Obviously take that with a big grain of salt.
@@Dowlphinburning oil increases emissions significantly, iirc it's one of the main reasons why Mazda killed the Renesis rotary: they used oil to lubricate the apex seals but in turn were pretty bad in mission control because of it
Just to be aware the software updates have caused some issues where it gets stuck, restarts constantly to where it drains the battery. There’s already reports of people having to have the whole entertainment system replaced cause of this. It basically leaves you stranded since it’s an integrated system.
It is amazing how long it has taken the legacy OEMs to realize their control systems design needed to be a lot more robust at the top level. Too much embedded subsystem/CAN bus level thinking. I own 2 MY 1 MMEs, and it's only after over a year since launch that Ford is beginning to get its act together around OTAing updates to the car. Ford CEO Jim Farley publicly conceded they weren't prepared and hadn't hired enough sw guys.
Combination of arrogance, NIH thinking, and Tesla making it look easy I guess. Whatever the cause it's definitely an engineering management failure.
@@MLHuntYeah, the OEMs seem to think software is easy and something they can just update later after they get the important stuff right. But the whole software stack is an important part now! It’s so aggravating knowing how much better it could be if management didn’t have blinders on
Even if they couldn't get the OTA to download and install, they still should be able to reprogram the dysfunctioning modules with a plug-in programming tool. When the only way you can figure to fix a software issue is to replace the misbehaving hardware, clearly something is broken in how you manage and deploy software. And when something you should be able to fix with a just a few tech labor hours can only be fixed by replacement of $1000s worth of hardware and many more technician labor hours, that's obviously really bad business-wise.
My Ford has that issue. Modern cars are rolling computers.
I found some useful workarounds that make this quite manageable, but it is darn annoying to have to worry about it at all.
My older (80’s and 90’s) vehicles only had that issue if you left your headlights on 😊
@MLHunt Why don't you think they can't reprogram using OBDII? Although if you worked an OEM or supplier you should know things like infotainment are usually too large file sizes to update over a CAN bus and they utilize USB updates. Dealers are always HW swap happy. Getting them to flash anything in service is unlikely.
Terrific content and interviews. And I appreciate how you manage the PR speak vs. tough questions with the factory reps. That said, it's a really hard sell to take a 2.7 I4 over the DI 5.3 V8. Will be interesting to see how the used truck market fares over the next couple years. Yeah, corporate and small biz fleets will move on to whatever is cheapest to run as they turn over their 100k-200k mile work trucks, but I suspect the demand for good condition V8s will keep prices high for a long time.
One of the best video you ever uploaded! Love mechanical and engineering deep-dives, especially by a good speaker such as this gentleman from GM! Thank you Geese'n'Gorillas 🙏
Does it come with lifter failure like the 5.3L/6.2L, then GM fights you tooth and nail to not repair/replace the engine? Can't wait.
There will be more failures than that
Government Motors fighting repairs? Never! Worst carmaker out there, and that's saying a LOT when you're in competition with the likes of Dodge/Ram/Jeep/every other Stellantis sub-brand under the sun.
Do you equally bad mouth Ford, Ram, and Toyota for all their prior issues, recalls, and disputes with owners over warranty coverage? I've got a list as long as my leg to back up all the issues every brand has had.
It's a totally different system.
i guess time will tell.
Love the conversation with the engine engineer. 👍🏽
It definitely convinced me not to buy this truck. That engine won’t last in an actual work environment. 😅
@@evildrizzt1 True. Automotive engineer here. Anything normally aspriated is better. Lower tech = more longevity. New vehicles are designed to fail out of warranty.

The way this engine is designed, it reminds me a lot of how reliable 4 cylinder diesels are built for tractors and so forth. This could end-up being as legendary as the LS.
Thanks for such a great deep dive.
Edit: I commented before I finished the video and I see I wasn't the only one thinking about this as built like a diesel engine. 😂
I'm sure the engineers did their part but the achilles heel for this truck is going the bean counters and other GM execs and what they end up f'n up.
It would be comparable to Mitsubishi's 4G63T. The 2JZ of 4 cylinder engines.
@@Josh-cw8by Absolutely, great point! Didn't even think about that even though I should have.
I owned a couple of 1G DSMs in the late 90s/early 00s.. currently own a unicorn 99 3000GT VR4. 🙂
@@tkin1973 Yeah, I definitely agree.
I haven't owned any American cars since I was a teen for good reason. I can't imagine spending as much as Ford's cost right now yet still get stuck with so many problems.
Legendary as an LS? IDK man....seems like Legendary as a diesel to me. I don't think getting a 2.7 I4 to rev up to 9k is ever going to happen.
Well done boys. I really appreciate the effort and consistency of your work. Because of channels like this one, we’re all much more knowledgeable with these products and I really feel like it helps to hold manufacturers more accountable to the products they’re releasing. Thank you
I remember the days when all it took to understand an engine basically came down to intake, compression, power, exhaust. Now, it’s turbos, direct injection, cylinder deactivation and all of this ancillary and computerized crap attached to the engine to manage and control certain functions like load management etc. From an engineering standpoint, it’s absolutely stunning and amazing. You’ve got to have an absolutely brilliant mind to come up with and understand some of these modern engines and mechanical marvels. From a practical standpoint, these new technologies wind up costing the consumer more money on the front end as vehicles become more expensive and the backend in terms of repairs, longevity/reliability. Long term, It winds up cancelling out any gains in fuel economy.
Couldn't have said it better myself. It comes down to cost, if GM is placing these everywhere (Traverse and Enclave are next), this could only mean one thing... it's dirt cheap for them to do so and may the consumer beware.
Going to do a write up on this soon. Everyone seems to be asleep at the wheel, especially politicans. If I had the money I would be hoarding older, clean, reliable vehicles that would last a lifetime. Cost per mile is going to go way up for everyone and politicians are behind it all.
I hear ya. The electric coolant pump is a bit disconcerting. Did they take the steps to do a brushless design? I doubt it. That being said I’ve had practice changing belt driven pumps on GM V8s. The standard weep hole leak failure. It’s not a difficult repair provided that you can get the f&@king fan nut to break free.
I love late 90's early 2000's vehicles for this exact reason. Just enough technology to be efficient enough without creating too many things to go wrong. The efficiency of modern engines is impressive, even if I have the right to repair some of these things i wouldn't want to
Remember when all you had to do was feed a horse grass and give it water? Pretty sure all these new internal combustion engines are going to be too complex and expensive for the average person.
Oh wait....
I appreciate the depth you guys go into these new trucks. So much more detail than every other youtuber
Man I tell you what, your all's videos never cease to amaze me. So very fortunate to be able to gorge myself with the information you all give. Much appreciated, yet again.
Toyota guy here. But man, I sure root for the big 3 to succeed. I really hope they can be known for reliability and longevity.
I'm a recent, and huge, SG fan. This is a perfect example of why. I have no interest in trucks, and generally not in GM product. But the info you uncovered and presented really made me appreciate this truck, this engine, and the engineers behind both. Really top notch production. Great work Jack!!!
Would love to see a video like this with a rep from company more known for its engineering excellence. This guy offers some keen insights into GM, but I’ll probably never buy a GM product. I would love an engineering talk on the evolution of the Toyota hybrid drive or the Porsche 911 powerplants. Still, this video is close to the best thing on RUclips. Great work.
there is! Motormouth interviewed the Tacoma chief engineer about the 2024 with the new turbo 4
The sit down discussion about the design of the engine was VERY enjoyable. Might have been one of your best engineering segments yet.
This motor has been through 2 generations and has done extremely well in the full size. My friend has had 2 and currently on a 22 Trail boss and loves the 2. 7
I'm a tacoma fanboy but for the first time ever I really like the GM offerings, they seem to have done a real good job with them
Great video. Love your interviews with engineers. His input on catch cans, PCV systems and cleaning the valves was very interesting.
Really like when you guys interview the engineers. kudos
You guys truly do car reviews like no other, appreciate what y’all do!
Wow, these interviews can be so amazing when you get the right person, someone who truly knows the details of the design. Awesome!
I weirdly like it, the look of it, the engine, seems like an honest truck. If only it was priced like an honest truck, but there is no more honestly priced vehicles.
They grabbed us by the balls years ago with the lobbying that brought about the level of car centric it you appreciate every day on your morning commute.
“Honest” is a myth.
I don't think they're particularly "overpriced" in relation to other consumer goods. Definitely artificially inflated but wages not keeping up is the biggest problem IMO.
@@rifleslol The biggest problem is people don't see the inflating wealth inequality as the main problem.
@@BeefIngot Agreed
It's great to hear from the engineers and their insights. That being the case, I'd certainly give it 2 years minimum on any new drive train. Although even still: my wife's 2019 civic 1.5 turbo was apparently the first year it was "fixed" after the 2016-2018 oil dilution issues. Well, now at 105,000 miles, she's at the point where she is getting light headed driving it from the gas fumes coming into the cabin. The dipstick smells like a gas can. Gonna change the oil one more time and dump it for a Toyota with no turbo and the dual injection. My N/A tacoma seems to be just fine....
Toyotas quality isnt like years ago (1990-2015), all OEMs in the auto industry are using cheaper parts to maximize earnings.........
I asked these guys this very question on their recent test of the new CRV. They admitted they didn't know for sure. There is so much misinformation about this it astounds me. Only posts like yours with real experience tells us, software upgrades and band-aiding hasn't done squat.
I really wanted to like a new Honda with tons more torque at low revs and much better fuel economy and even quicker acceleration, than my old 2.4 but still, nothing modern beats it, not when all things factored in.
I wish rust wasn't an issue. Those who live where salt doesn't disintegrate their vehicle are so fortunate.
The issue really is for those who do much fewer than average miles per year. For some, they have a 19 year old car that still only has 80k miles. Everything works including original air conditioning but underneath, rust is front and center an issue even though the paint is like new still in 98% of the places.
CAFE and EPA and government that caters to the agendas are the crux of all of our disgruntlements. Factor in being overcharged 35 to 40!% for what's available to us in this particularly shitty period of vehicle ownership and you've got a hot mess with no end in sight.
Unprecedented times we're witnessing.
These turbo engines contaminate the oil fast. That means very frequent oil changes.
Likely injector o-rings need to be replaced. I've seen this on several DI cars where you can smell gas in the cabin once they get older.
@@user-3tf67bk46u We had a 1999 civic that went 300k with just routine maintenance (then sold it running fine). Then a 2001 civic that went 200k with just routine maintenance. Sold that 2001 (again, running fine) for a 2014 Impreza (we live in the snowy northeast) but had a lot of quality control issues, and figured we'd go back to that reliable Honda product we always enjoyed. The car itself is built well, and has no rattles or weird quality issues at 105k, but their drivetrain is no longer built for long term reliability. This car lives a best case scenario as well, as we always changed the oil at 5k even though I believe Honda requires it a 10k. It also drives for 45-minutes to work, then 45 minutes home, all highway. No short trips, so it stays at operating temperature for most of its life. It would be a good lease car I suppose...
Thank you for another excellent deep dive. I hope more manufacturers get on board with you guys for more of these in the future.
Appreciate the deep dive, but GM must appreciate the opportunity as well. This will be a great video to revisit in 6 years.
I still have PTSD on anything with cylinder deactivation. I definitely take the wait and see approach.
Makes me want a new Dakota with the 3.0 Hurricane engine. It would be the best mid size truck experience for 5,000 miles before all the factory recalls and quality defects permanently garage it at the dealer.
Life is too short to drive reliable cars😂😂
You're confused with a Ford.
You don’t want to find new roads?
@@ettiennenathanit is but rent, mortgages, healthcare, and general inflation kinda forced our hand. Im just waiting for everyone whos buying cars at these prices to lose rediculous amounts of money on em when both the market crashes and the "tech" thats in em goes into a perpetual cycle of giving up the ghost
I agree with you. My comment was mainly satirical. I drive an outdated Toyota and 20 year old BMW.
I really appreciate these deep dives with engineers and other professionals. Thanks for the insights!
My dad just got the 2.7 in the Silverado and is really liking it. Good economy and tows his boat just fine. He had the 3.7 before and it had lots of dealer visits
I really do love how these truck look. The interior is amazing compared to previous years. But I don't think I can give up my 2.8L Duramax yet. The fuel mileage is just so good and I love everything about it. I will admit that I am having a hard time accepting a 4 cylinder gas engine in a truck (especially a 1/2 ton), but maybe someday I will change.
Same here I have the 2.8 bison. 2022. I just love the sound of a diesel over a gas. Now the new 23’s look great just wish GM would have kept the diesel option. Cause I’d be banging my down payment on their desk yelling take my money. But sadly they don’t so I’ll be working towards being a million mile club member.
As a former GM fan boy. I hope this 2.7l is as good as promised
Just found your channel. Outstanding reviews and a cut above the breadth and depth that most other channels go into. Not full of pomp and filler, but you guys really hit the nuts and bolts that potential buyers should know when considering any of the vehicles you review. This video in particular, is the best and most comprehensive ZR2 review I’ve seen yet. Very much appreciated, gentlemen.
"Nice cylindrical bores". Always a great feature to have.
Now THIS is a detailed review 👌
Once again, another excellent and informative review. Yes, it looks like Chevy ditched the interior trim that looked like it was designed and cast by playskool. The exterior is sharp, and the interior looks like a place you could spend a day driving and still feel comfortable.
Thanks for all the Great Videos with Real Content that Took Work to Create 🎉
I have a 2.7 Ecoboost V6 in my F150. It's a great engine with amazing power. It's impressive that they made this engine a 4 cylinder.
There definitely seems to be a lot of features that could be catastrophic if they're common failure points. Electric water pump, transmission fluid and oil warmed up by coolant which could mix fluids if they fail, Turbocharger wastegate which can leak and linkage which can loosen up, and DI carbon buildup. Time will tell.
I love how there is an electric pump in the tranny that turns on every time you open the door. WTF?
@@robmunach3870whoops forgot my wallet. Let me go back real quick. Yeah def a wear item hopefully it’s not going to be bad to replace.
I do hope they fix the oil consumption issues. I had a 2022 Silverado 1500 with the 2.7 HO that I bought brand new. I always let it warm up before getting on it, only towed a 4k Lb uhaul 1200 miles, and generally treated it really nice.
It used just over 1 quart of motor oil by 6500 miles. Halfway to my 15,000 mile oil change I had added a quart and near to the change itself had to add another quart. At the 22k oil change I had also added 2 quarts to keep it above low.
I never beat on this truck, I kept the autostop off, and generally it was a highway queen. I put on 25k miles in one year of ownership and it burned through almost 5 quarts of oil in that time. It was a large part of why I traded it in. This is obviously anecdotal but I was highly disappointed in the engine.
I know you were going by the recommended oil change interval, but 15K interval change is way too much. You got rid of the truck but I keep my oil change intervals to 5-6K. Modern cars burn oil because the oil change intervals are too long.
I had a brand E350 Benz wagon that was burning oil also, it was on 10K oil changes.
@@goforbroke2 I must have been unclear, I changed the oil the first time at 6969 miles (I only remember this one because it was a funny accident), then around 15k, lastly around 22k.
@@peterdelacruz5650that sounds more like it. You're better off changing the oil every 5k max on these newer engines.

Appreciate the deep dives on the engines and stuff you guys do. Might be a long shot and I don't know if anyone there would be interested in helping you guys out, but it would be nice to see a send off type of video for the Challenger and Camaro with some of the people who helped design them, as they are sunsetting this year.
This engineer is responsible for the design of this super cool engine and he’s rocking a Seiko SKX009. Love it.
I know that emission standards killed diesels in the USA but this class of trucks would benefit a lot from a diesel engine.
this just made me more excited for you guys to review the new taco, landcruiser, and gx550.
The first two, yeah, but the GX550 is getting the TT V6, not the iForce Max 4 cylinder hybrid drivetrain.
I swear; at the rate we're heading, everyone is going to be driving semi trucks with 4000 hp 4 cylinders
I have a 2022.5 Silverado with the 2.7 HO. I love it. Came from a 2018 5.3 Silverado before it. So far in comparing all of my documented fuel economy, I'm up over the 5.3. Per tank fill up MPG I consistently saw 17-18mpg in the spring/summer/fall and 14-15mpg winter with my 5.3. Long trips average MPG most was 20.9. With the 2.7 HO and the same driving styles as before I've not seen less than 17mpg in winter, and spring/summer/fall have been consistently 19-22mpg. Long trips I've been able to pull 23-25mpg for the trip. It tows better and it is as fast if not a hair faster than the 5.3 I had. I drove a 2023 Turbo Plus Colorado and it absolutely blew the 3.6 out of the water. Its the closest we will get to the 2.8 Duramax, minus the impressive MPG that got.
Thanks for the great real world statistics! Sounds like the 2.7 only gives marginal performance gains over the 5.3 at the cost of complexity. I don't think a 4 cylinder is going to cut it for me.
@@moabman6803 I would say above marginal. Towing is a better experience than the 5.3. It weighs less than an identical truck with a 5.3 and therefore feels every ounce as fast as one (perhaps a tenth or two faster?). Plus, no Dynamic Fuel Management lifters to have concerns over which, is still a thing but perhaps a little less common at the moment. 2020-2022 was a rough patch for the 5.3 and 6.2 and low mileage DFM lifter failures.
I see cost cutting.
It’s a 4 cylinder because it’s cheaper and easier to fit in an engine bay. I don’t buy the piston diameter per horsepower explanation for a second. I’m thinking it’s a fairly safe bet that Ford’s 2.7 is a more expensive engine.
Open deck blocks and high cylinder pressures usually don’t go together. But it’s cheaper for GM to manufacture.
Why carry on with the 8 speed AT that doesn’t have a good reputation? It’s cheaper for GM.
This engine is barely more efficient than the 5.3 V8. But it’s a cheaper for GM than developing a electric hybrid.
If valve carbon buildup could be properly solved without adding traditional injectors, along with the direct injectors. Why are other manufacturers still adding additional injectors. I I’m saying I don’t believe the engineers claim that they have created a cheaper solution that works.
I know that the timing gear was mentioned, but I’d like the engineer to strait up say “This engine will not break chain guides.” I do appreciate the choice of chains over belts. Especially over wet belts that some engineers think are just fine.
I’d like to know. If you were more critical during your GM interview, would you risk losing access to these engineers for future questions?
all facts
Open deck with 27+ lbs of boost. What could go wrong?
Rigth?????
I don't understand why anyone would design an open deck for an engine intended to have a turbo.
Something, Something "design requirements"@@rightwingsafetysquad9872
Cast aluminum everything and open deck....but "This engine was built for a lot of boost"
All contained in a cast aluminum block? It won’t last long enough to see the warranty expire. 😅
While the engineer was taking about development of the engine, I could swear, it almost sounded like they were trying to make this engine so good, that it comes the next "LS Swap" or "K-Swap" of the next generation.
I mean, the LS swap phenomenon has no doubt helped GM in sales of new cars, parts for old cars, and of course, crate engines themselves with the GM Performance branch.
This engine will basically print money for them if it succeeds with people, and it's going to be to the enthusiast's benefit too!
Nice to see you guys step into the truck world, as a lot of us North Americans own both cars & trucks.
Just my opinion, but I think GM has hit a grand slam with this Colorado/Canyon offering. The powertrain, capability, & pricing seem to be spot-on with most modern truck buyers’ needs. I’d easily take a GMC Canyon over a Tacoma or Ranger; probably go for the Elevation package in the low $40s US.
Starting to save money to replace my aging 90's Ford Ranger. The LT trim level of this truck actually seems obtainable for an average buyer.
Obtainable =/= Good Long Term Investment
@@Traysandor 99% of vehicles are depreciating assets. what's your point?
@@TraysandorYou don't buy a vehicle to "invest". It will only ever cost you money unless you use it for a business.
@@Traysandor Cars arent investments. Go buy gold or something
I have an 05 Ranger and I'm saving my money to buy a 2010 or 2011 Ranger. I wouldn't touch one of these new trucks with a 10' pole.
Crazy that these boys have finally found out high boost small aluminum block engines and hybrid tech after a lengthy Honda deal👀
I recently had a Silverado with this engine in it for about a week and I was absolutely blown away by how good it is. It really is a shame that they dropped the 6 foot bed in the Colorado, because that is going to force us into either a Silverado or a different brand. I don’t mind the Silverado, currently have one with the 5.3 L, but I really don’t need a full-size truck, just a 6 foot bed.
Vote with your money and let them know. 👌👀
Real automotive journalism! Kudos!
This is fast.. well - fast - the GEESE guys have been around for literal CENTURIES - turning out to be the most factual, comprehensive and technically informative - outlet/review all things automotive. Because - let's be honest. Who else is there (no, not the song by that Scandinavian band). Throttle House mostly hoon around and report their track times - and perceived "feelings" on the respective product - which is all great - and their production is mind-blowing - but they don't go as much into technical stuff, which is a shame - then there's another Canadian duo - the Straight Pipes - which have turned borderline unwatchable because of questionable (actually questionable) apparel choices - and when it's at that level - it really becomes kinda annoying - then there's the The Fast Lane/TFL Trucks and their channels - which don't achieve the same level of seriousness, somehow, as manifested by the GEESE guys, weirdly enough - and who else? Real large broadcaster/paid former TV channel outlets like Hagerty in US and TopGear in UK? Yeah, maybe - but again, neither of them have ever seen a car lift, it seems. So kuddos to both of the GEESE guys (jeez I just invented an awesome term) - both the OG one - and the immigrated one (I mean... added to the team - not immigrated from Taiwan as he claims) - thanks for the great car and truck content throughout the years - although I'll probably never buy a single car based on your reviews - I've watched 99.9% of the videos - and will keep doing so. Greetings from Latvia, keep up the work.
We're going from a golden age of automotive performance to a future of big displacement, low rev turbo 4's & hybrids + EV's. Can't help but be glad I'll always be old enough to remember the days of 809348 Hellcat versions & rip snorting Focus RS's.
I’m more interested to see the reliability in the tech and interior inside after 5+ years. It looks really nice brand new. GM really nailed the design, an other awesome video and great info on the new engine.
I enjoy these discussions - I've seen this engineer do a few of these. I believe it might turn out to be a reliable engine, but it will be a long time before it eclipses my LS2.
I love almost everything about this truck. HOWEVER, it may be that I am hung like a field mouse, but I do struggle with the idea of having a 4cyl truck- especially at the ZR2 price point.
For me it's a question of reliability with the components around the engines in the long term. I've got a truck that's 28 years old and another that's 22. I wonder if these engines will be able to be kept so long.
@@Moonless6491They won’t. More profitable to the company that you have to buy another truck after warranty expires than to create a reliable one that lasts decades.
Question: Do you need a truck? (If not, then the 4-popper style clash would be less distinct.)
@@Moonless6491if done right, they can last, Toyota makes a turbo diesel 2.8l 4cyl and they're pretty reliable for the torque they make
You can struggle with it but it's all in your head. A modern 4-cylinder will slay a traditional V8.
YES. Give us all the content. We love it.
Love your channel. Great job with the depth and breadth of this review. Keep up the awesome work!
I have a 2023 Canyon Elevation 2wd. The 2.7 4 cyl HO was one of my driving factors in buying this truck over the competition. After driving everything in its class I am very happy with my purchase/decision.
27psi at low rpm in an open deck 4 cyl? Will be very curious to see how the rod bearings / piston sleeves tolerate that over time. Curious if they took some engineering from the duramax diesel engines and applied it to this.
Just hope they aren't using the rods and pistons from the 2.8 Duramax. Those things love to bend and crack when pushed hard. Will be interesting to see how this engine handles over time.
by 100,000 miles the rings and bottom end will be cooked for sure
I'll stick with a NA V8 thank you.
Good video quality as always SG
Everybody says that like the lifters don't all fail constantly. I'll never really understand that attitude. N/A V8s have proven chronic issues but they get treated like they are rock solid.
Going to be honest here. I love the new Colorado for sure. and this is the hands down best video you all have done in a while. Keep this style going for sure. Good job
Thanks guys, that was very interesting and useful info. I appreciate the peak behind the curtain
He did absolutely nothing to explain why carbon buildup on the intakes will not be a problem. Because of course, it will
Really fast, swirly air flows blowing the oil off the valves.
Because, as we all know, blowing oil off a surface works really well. 😏
@@Dowlphin the swirly air will help and if the PCV system is working well, there really shouldn't be a lot of oil vapor in the intake tract. If you had to clean the intake valves every 80-100K, you could probably live with that.
Did you watch the video? He said the PCV system is highly developed and that the way air enters the cylinders it helps clear off the valves. This was his explantion...I'm not saying I believe it.
@@TML34 The PCV system itself is not to minimize oil vapors in the intake tract but to get rid of them. But I assume the removal of the piston oil spray system could be related to reducing the presence of oil vapors in the system, hard to say.
Valve cleaning service ... yeah, that would be expensive, removing the whole cylinder head, because I doubt you can do it purely chemically once the stuff has already burned itself into the valve surface. So you'd have to actually remove the valves.
Furthermore, they say DI improves emissions, but the system, due to this issue, counteracts itself: From the moment you use the engine to the point where you decide it needs cleaning, the emissions situation deteriorates gradually.
@@Dowlphin you shouldn't have to remove the cylinder head to clean the intake valves, just remove the intake manifold.
It seems a very well thought out engine, I have to say.
This comment will age like milk.
@@fortheloveofnoise The 2.7 has been around since 2018 and has had minimal issues and loads of time for refinement
@@fortheloveofnoise Yummy yoghurt!
Great job on the video fellas, you guys are killing it
"nice cylindrical bores". I'd hope so, lol. This was a good interview on a product I'm not very interested in. The guy you interviewed was great.
Truly an exceptional review. I was on the fence between this & Taco, until Colorado was unveiled July '22. Slam dunk decision for me. Looks like GM knocked this out of the park. My ZR2 will be delivered this week.
Any engineer rocking a Seiko SKX009 is good in my book.
That alone says all I need to know about the engineering team… considering the truck just for the fact. I’m not sure what that says about me.😂
Glad I’m not the only one that noticed!
I love this format, keep up the fantastic work boys.
Just ordered mine! Can't wait ti get it. Loved my last ZR2
They will be awesome till the warranty expires!
I am a broken record at this point, but cash-strapped Nissan could instantly jump to the top of almost everyone's mid size truck list by just installing the 5.6 v8 from the now-cancelled Titan into the Frontier. The truck will run a million years, will cost the company basically nothing, and will satisfy the actual market demands of shoppers in the segment.
@Arkeo36 honestly I don't know if is the Japanese division or the American division that are completely idiots! Also imagine a new xterra with the frontier looks and either tje v6 twin turbo or the v8!
@@Arkeo36 Just like those who pine for an inline 6 in this Colorado, beyond cost is weight and handling. The Frontier in 2 WD already feels front heavy. The V8 would exasperate that feeling.
And it's not the most fuel efficient 5.6 by any stretch.
Nissan should go back to their name Datsun, if they really want to leave some of their unpleasant joint ventures behind them. And strike a deal with Aesin no matter how much Toyota might charge them. There's a chance for Nissan..at least they don't insist on selling boxers.
@@Arkeo36Shoppers are "demanding" a 13MPG midsize truck? Or People are squawking about how they'd definitely buy one?
@@user-3tf67bk46u (exacerbate...)
My first car was a 1968 Chevelle that I paid 800$ for. Since then I have had zero interest in Chevrolet offerings.... until now. This new colorado in TrailBoss trim for 40k seems reasonable-ish given the current market. Kudos to the team, I'll definitely be checking one out once they hit the lots.
i'm old user of Taco's and Tundra's... and with all the problems that the new Tundra have (Rod knock and spun bearing), i really focusing my new purchace on this truck... and yep it's look good.
This level of honesty is why I come here
The current format of Savagegeese with Jack being so influencal in the approach. And having a engineering degree. He seems to have lot of interest in interviewing the people that may have had a hand in the decision making when it came to the car development.
Now, from a viewer count perspective I am not so convinced, that this amount of it at least, is what the core of Savagegeese fan base care this much for. Listen to some PR acceptable answers from some corporate people ( ala Dark Horse video😴 )
Now in this case ( I had already seen a video with this senior engineer guy go through the engine architecture )
I still haven't come to hear from either Jack or the one taken the past interview I saw with him.
Asking him the basic questions as for exp how they manage to run 27psi of boost that comes in quickly and on a high compression motor on top. All while running it on 87 octane fuel?( maybe the HO require 91, but I doubt GM would make a version that would require 93 Oct )
That is type of info I personally would much rather want to hear the answer to. Then just have to spend the time listen to some generic corporate acceptible talk. It is far from being savage enough. And I know Mark knows that well.
Sad problem is 99% of truck buyers would never fuel with premium even if it required it then a slew of issues would crop up because of it
Props to Kevin for wearing a Seiko SKX!!! 1:00
Ha! I thought I was the only one who zoomed in to check.
😂😂😂😂
I’m🤓just made a post saying the same thing🫡
As always, very informative!
The turbo enthusiast crowd hears thing like 'removed oil squirters' and 'transmission weakened by 50%' and they think 'darn'.
I kind of wish they kept the Camaro, and put this into a base model to replace the current 2.0T.
Open deck + 27lbs of boost + thermal cycling…..we’ll see….at least the water pump can run post shutdown….Porsche 944 had that in the 80s.
I'm not a Chevy fan but I am rooting for this engine. I'd love to have a detuned overbuilt version as my last truck ever, I'm just waiting for someone to deliver a quality proven product.
I really want to hear Jack's opinion about how much effort went into/how good the upcoming Tacoma is once you guys have had your week with it. I have a feeling it's gonna be a big change if heart.
