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?
@@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 UA-camrs, 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?
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.
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.
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.
@@AllenWeraYou 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.
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 UA-cam 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!
@@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.
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.
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
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.
@@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.
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.
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
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.
@@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.
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.
@@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.
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. 😂
@@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.
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 🙏
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....
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
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.
@@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
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....
@@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...
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 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.
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.
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.
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!!!
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.
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.
The engine is least of my worries on this thing. Is cruise control standard on this $40k+ truck yet? Headlight controls still buried in-screen on a submenu? Did they fix the screen blackout issues? Economy car levels of quality for luxury car prices, gotta love what midsize trucks have become.
Uhh inflation has moved that luxury upstream. Before 20k used to be exotic car pricing. Think the dussenberg 20k, a great depression era car that cost 20k or roughly 10 houses. 20k now gets you a maverick, or the cheapest kia’s.
Depends on trim. Cruise control is standard on a ZR2. Its in a cheap option package for the less expensive trims. I know by your comment you watch TFL... that was honestly more a screw up Andre and his dealers' part. If they had realized when ordering it was just a cheap option they would have checked that box and you would have never thought about this at all. Likewise there isn't an "screen blackout issue." Yes, again, I know Andre's truck had that issue but this isn't some systemic problem.
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?
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.
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.
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.
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.
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.
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!
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.
Well, it's a truck. 🤷♂ It gets tax benefits for being bogusly declared a work vehicle even though the work vehicle is a specific different trim level.
@@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.
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.
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.
You heard it here first. We made it less efficient/more emissions to save money. Weird because it's illegal to delete particular trucks for the same exact reason. Only difference is one side votes the other side pays for their vote 🤔
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'm no engineer but saying they tried to keep it at 115 hp per liter because it is "super reliable" sounds unconvincing. You know what's also reliable? A bigger engine making the same power.
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.
I just test drove the Tacoma, Frontier, and Canyon today. Out if all of them the 2.7 felt the most raw and unpolished but not in a bad way if that makes sense. If I was going for comfort, it would be the Frontier, for tractor like reliability, it would be the Tacoma, and shenanigans would be the Canyon.
I didn't understand 88.9% of the words / terms Kevin said here, but it sounded nerdy and awesome and I'm grateful you guys brought us this interview. SG is by far the best car review channel online.
I work at a GM/Chevy dealership, and very few of our products really "wow" me. The Colorado, Canyon and the Trax are the only three vehicles that really get me envious and has me wanting to buy one. They just look amazing, and I'm a fan of smaller trucks so the Colorado and Canyon are both right up my alley.
14:10 an electric water pump is actually a great accessory. It can vary the speed and flow of coolant through the engine and in conjunction with the temp gauge in the radiator provide quicker engine warmup in cold temps and better cooling in hot temps, especially in low RPM high load. Great change for GM imo.
@siddharthgoyal4008 yes,it will never break because only runs %100 of the time, light load or not! Knowing gm they cheapen out 30 cents and made the insides all plastic.
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.
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.

It seems a very well thought out engine, I have to say.
The truck in this video is the ZR2. I don’t understand why they advertise this truck when GM is not building them. There are none available at the dealers. You would have to order one, like I did , and hope it comes in , 6moths to 2 year wait. GM is in the business of building and selling cars. So why won’t they build them ???? It’s ridiculous. 😮 I stopped waiting and bought a 2023 ford lariat tremor. $51k OTD. Great truck. ! Has higher payload , tow capacity and better gas mileage than the ZR2. I’m getting 24-26 mpg on the highway 👍
As someone who is the process of getting a GMC Canyon, i love these deep dives into the engineering and putting my insecurities with a newer powertrain at ease. Keep it up guys ❤
I have this engine in our 2021 Silverado 1500 and can pull a 7000 LB trailer all day long with no problems. Also pulls hard up hills with load. Only bad is it only gets 8 MPG when pulling a load this heavy. I have a 2024 Duramax on order with a 1000 ft LB of torque. Still this engine is really impressive.
New Ranger & Tacoma have already been announced; not sure why you'd make such a confident proclamation that this is best in class when you have yet to assess those two next-gen vehicles.
Ah yes, the launching of the Colorado, in California. Like launching the Aspen at Tahoe, the New Yorker in Chicago, Tahoe at Aspen, and the Granada in Hawaii. However, not quite as bad as launching the Le Mans at the dragstrip and not just because you are not running enough anti-squat in your Pontiac.
22:46 if you want a 4cylinder to sound good, you have to do a V4 configuration or an inline crossplane . As someone who owns a V4 tuono, there is nothing like the sound. An inline 3 cylinder or, again, inline 4 cylinder with a crossplane crank would be a close second.
So the ancient Tacoma is outselling this thing 3 to 1. When the new one comes out, that gap will only go up. Also Ridgeline is doing quite well despite the hate about it not being a truck. It outsold the: Canyon, Ranger and Gladiator in Q2 of this year. Anyone that tows anything over 4-5k pounds regularly isn't buying a midsize truck to do so. That's what 1/2t are for.
The Tacoma is 20 years old and feels like it's 30. Did they ever ditch the rear drum brakes? Even the Nissan is better. Toyota is coasting on past success. They ruined the Tudra by trying to copy Ford.
When I hear this man talk about the engine it makes me want the truck. But then I read about 16mpg and the screens dying and no cruise control and I'm like...nah I'll pass. 27 pounds of boost is just not sustainable. At this stage in civilizational decline, these kind of vehicles will not survive the 10 year mark, and with the high cost associated with new vehicles, even basic trucks included, it just doesn't seem like a good investment.
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 UA-camrs, 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.
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.
@@AllenWera 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.
@@AllenWeraYou 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.
@@AllenWeraI’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 UA-cam 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.
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!!!❤️
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
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.
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
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
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.
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.
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.
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 🙏
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....
Dude seems knowledgeable and he’s rockin’ a classic SKX009….!

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 appreciate the depth you guys go into these new trucks. So much more detail than every other youtuber
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.

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.
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.........
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...
@@TheBandit7613 Yeah, we always did it at 5k, but thats not cutting it anymore. Time to say goodby as it's not going to get any better...
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 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.

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!!!
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
Wow, these interviews can be so amazing when you get the right person, someone who truly knows the details of the design. Awesome!
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.
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.
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.
The engine is least of my worries on this thing. Is cruise control standard on this $40k+ truck yet? Headlight controls still buried in-screen on a submenu? Did they fix the screen blackout issues? Economy car levels of quality for luxury car prices, gotta love what midsize trucks have become.
Uhh inflation has moved that luxury upstream. Before 20k used to be exotic car pricing. Think the dussenberg 20k, a great depression era car that cost 20k or roughly 10 houses. 20k now gets you a maverick, or the cheapest kia’s.
Just leave them in auto like you already do.
@@FXIIBeaver Your options will soon be this or a cyber truck, that is if you like door wedge shaped trucks.
@@NotAnonymousNo80014 cyber truck is never releasing but keep dreaming.
Depends on trim. Cruise control is standard on a ZR2. Its in a cheap option package for the less expensive trims. I know by your comment you watch TFL... that was honestly more a screw up Andre and his dealers' part. If they had realized when ordering it was just a cheap option they would have checked that box and you would have never thought about this at all. Likewise there isn't an "screen blackout issue." Yes, again, I know Andre's truck had that issue but this isn't some systemic problem.
Appreciate the deep dive, but GM must appreciate the opportunity as well. This will be a great video to revisit in 6 years.
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. 😅
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
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.
"Nice cylindrical bores". Always a great feature to have.
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.
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.
Really like when you guys interview the engineers. kudos
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.
now we deactivating cylinders in a 4 cylinder? what could go wrong?
It's a completely unnecessary feature. Basically a peepee measuring contest for engineers.
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.
I know that emission standards killed diesels in the USA but this class of trucks would benefit a lot from a diesel engine.
This engineer is responsible for the design of this super cool engine and he’s rocking a Seiko SKX009. Love it.
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.
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.
This level of honesty is why I come here
Emissions THE single most evil word in the automotive world
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!
Great video. Love your interviews with engineers. His input on catch cans, PCV systems and cleaning the valves was very interesting.
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.
The turbo enthusiast crowd hears thing like 'removed oil squirters' and 'transmission weakened by 50%' and they think 'darn'.
Crazy that these boys have finally found out high boost small aluminum block engines and hybrid tech after a lengthy Honda deal👀
Complete redesign of the truck but still has antique leaf springs. Thank you General Motors. Anything to save pennies
Well, it's a truck. 🤷♂ It gets tax benefits for being bogusly declared a work vehicle even though the work vehicle is a specific different trim level.
Leaf springs are superior to coil, as are torsion bar
It is so you can move more stuff...not that you would get that, as the average truck buyer is just using it to go through the McDonald's drive thru.
@@fortheloveofnoise what a bunch of nonsense. Besides, if you wanted to move more stuff you get a real truck
Now THIS is a detailed review 👌
You guys truly do car reviews like no other, appreciate what y’all do!
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.
Thanks for all the Great Videos with Real Content that Took Work to Create 🎉
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.
Real automotive journalism! Kudos!
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.
You heard it here first. We made it less efficient/more emissions to save money.
Weird because it's illegal to delete particular trucks for the same exact reason. Only difference is one side votes the other side pays for their vote 🤔
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'm no engineer but saying they tried to keep it at 115 hp per liter because it is "super reliable" sounds unconvincing. You know what's also reliable? A bigger engine making the same power.
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 just test drove the Tacoma, Frontier, and Canyon today. Out if all of them the 2.7 felt the most raw and unpolished but not in a bad way if that makes sense. If I was going for comfort, it would be the Frontier, for tractor like reliability, it would be the Tacoma, and shenanigans would be the Canyon.
It's kind of weird to hear Nissan as a comfort pick. Goes to show they aren't the same brand they were 20 years ago.
@@NiSE_Rafter It was a highly specd out model sp that helps. But they are definitely much improved.
"We focused on value" - Kevin Luchansky, Assistant Chief Engineer at GM
Great, this motor won't last.
obviously
That’s the goal.. buy this LS swap it and throw this motor in the trash 😅
I’M A RIDGELINE OWNER AND I AM TRIGGERED JACK IT’S A REAL TRUCK 😂 (hey at least I have six cylinders)
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🫡
I didn't understand 88.9% of the words / terms Kevin said here, but it sounded nerdy and awesome and I'm grateful you guys brought us this interview. SG is by far the best car review channel online.
"This engine was built for boost" *shows tiny 2-bolt main caps
I work at a GM/Chevy dealership, and very few of our products really "wow" me. The Colorado, Canyon and the Trax are the only three vehicles that really get me envious and has me wanting to buy one. They just look amazing, and I'm a fan of smaller trucks so the Colorado and Canyon are both right up my alley.
What about the full size trucks?
14:10 an electric water pump is actually a great accessory. It can vary the speed and flow of coolant through the engine and in conjunction with the temp gauge in the radiator provide quicker engine warmup in cold temps and better cooling in hot temps, especially in low RPM high load. Great change for GM imo.
In principle you are correct, unfortunately the reality is the General Motors likes to make everything as cheap as they can. So failure is prescribed
Everything is great until it breaks and all replacement parts are nationally backordered.
@@thEM1ghtyricerideally electric water pump shouldn't break because it for most cases would need to run very light.
@siddharthgoyal4008 yes,it will never break because only runs %100 of the time, light load or not! Knowing gm they cheapen out 30 cents and made the insides all plastic.
I hope you have to remove the transmission to access the water pump
"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.
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
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.
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!
Never mind the problem by 3.6. My other transition replaced once, but I've never had an engine problem. This is always been a transmission issue.
The truck in this video is the ZR2. I don’t understand why they advertise this truck when GM is not building them. There are none available at the dealers. You would have to order one, like I did , and hope it comes in , 6moths to 2 year wait. GM is in the business of building and selling cars. So why won’t they build them ????
It’s ridiculous. 😮
I stopped waiting and bought a 2023 ford lariat tremor. $51k OTD. Great truck. ! Has higher payload , tow capacity and better gas mileage than the ZR2. I’m getting 24-26 mpg on the highway 👍
This makes the simple no frills Nissan frontier look very appealing
New ones are junk….
As someone who is the process of getting a GMC Canyon, i love these deep dives into the engineering and putting my insecurities with a newer powertrain at ease. Keep it up guys ❤
Being from Europe I don’t care much for this engine but the technical details were fascinating.
I have this engine in our 2021 Silverado 1500 and can pull a 7000 LB trailer all day long with no problems. Also pulls hard up hills with load. Only bad is it only gets 8 MPG when pulling a load this heavy. I have a 2024 Duramax on order with a 1000 ft LB of torque. Still this engine is really impressive.
I really hope they bring back the 4 cylinder duramax, now THAT was a real 4cyl.
“Man I sure wish my truck was more fuel efficient. Even if it was less reliable”
The new Colorado/Canyon look great & have good specs. BUT, I worry about the good ole GM quality & longevity. 🧐
GM chassis engineering has always been top notch, glad to see they didnt stumble with this one either
I like this design. My 07 5.3 needed a rebuild because of the hydraulic AFM. This doesn’t appear to have that issue. Time will tell I’m sure.
New Ranger & Tacoma have already been announced; not sure why you'd make such a confident proclamation that this is best in class when you have yet to assess those two next-gen vehicles.
Ah yes, the launching of the Colorado, in California. Like launching the Aspen at Tahoe, the New Yorker in Chicago, Tahoe at Aspen, and the Granada in Hawaii. However, not quite as bad as launching the Le Mans at the dragstrip and not just because you are not running enough anti-squat in your Pontiac.
22:46 if you want a 4cylinder to sound good, you have to do a V4 configuration or an inline crossplane . As someone who owns a V4 tuono, there is nothing like the sound. An inline 3 cylinder or, again, inline 4 cylinder with a crossplane crank would be a close second.
So the ancient Tacoma is outselling this thing 3 to 1. When the new one comes out, that gap will only go up. Also Ridgeline is doing quite well despite the hate about it not being a truck. It outsold the: Canyon, Ranger and Gladiator in Q2 of this year. Anyone that tows anything over 4-5k pounds regularly isn't buying a midsize truck to do so. That's what 1/2t are for.
The Tacoma is 20 years old and feels like it's 30. Did they ever ditch the rear drum brakes? Even the Nissan is better. Toyota is coasting on past success. They ruined the Tudra by trying to copy Ford.
@@VortexArcade they do have drums in 2023. New model will have disks and only 4cyl turbo. No more v6.
@@user-3tf67bk46u Sounds like you're drinking something of Toyota's, and it's not Kool Aid.
Its amazing to me that even with a 4 cyl that it runs on 2. Guess we'll be seeing a vtwin kohler engine next 😅
When I hear this man talk about the engine it makes me want the truck. But then I read about 16mpg and the screens dying and no cruise control and I'm like...nah I'll pass. 27 pounds of boost is just not sustainable. At this stage in civilizational decline, these kind of vehicles will not survive the 10 year mark, and with the high cost associated with new vehicles, even basic trucks included, it just doesn't seem like a good investment.
The Colorado is really winning my heart for this segment.
YES. Give us all the content. We love it.
4 cylinders are cool but I'm waiting for the inevitable future when we're driving 1 cylinder trucks
The axle swayed forward looks great.
