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).

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

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.

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.

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!

Man I can’t wait to see a comparison of the Colorado and Tacoma This is going to be interesting for 4 cylinder trucks

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.

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 KZfaq automotive channel by far.

GM Jack did a great job of condensing lots of information.

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.

I know Jack was resisting the urge to mention the B58 to the engineer

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.

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 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.

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. 😂

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 🙏

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.

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.

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.

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

If it fits a light machine gun in the bed, I'm sold.

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.

Love the conversation with the engine engineer. 👍🏽

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.

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.

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:)

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!

Great video. Love your interviews with engineers. His input on catch cans, PCV systems and cleaning the valves was very interesting.

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 KZfaq. Great work.

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!!!

Thank you for another excellent deep dive. I hope more manufacturers get on board with you guys for more of these in the future.

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....

The sit down discussion about the design of the engine was VERY enjoyable. Might have been one of your best engineering segments yet.

I really appreciate these deep dives with engineers and other professionals. Thanks for the insights!

Thanks for all the Great Videos with Real Content that Took Work to Create 🎉

I still have PTSD on anything with cylinder deactivation. I definitely take the wait and see approach.

Now THIS is a detailed review 👌

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.

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'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

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?

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

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.

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.

Appreciate the deep dive, but GM must appreciate the opportunity as well. This will be a great video to revisit in 6 years.

Real automotive journalism! Kudos!

"Nice cylindrical bores". Always a great feature to have.

this just made me more excited for you guys to review the new taco, landcruiser, and gx550.

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.

I love this format, keep up the fantastic work boys.

Thanks guys, that was very interesting and useful info. I appreciate the peak behind the curtain

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.

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.

As always, very informative!

Great job on the video fellas, you guys are killing it

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.

Open deck with 27+ lbs of boost. What could go wrong?

Love your channel. Great job with the depth and breadth of this review. Keep up the awesome work!

Just ordered mine! Can't wait ti get it. Loved my last ZR2

I know that emission standards killed diesels in the USA but this class of trucks would benefit a lot from a diesel engine.

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 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.

Great video. Lots of information and very well done. Quick question: What were all of the warning beeps for? Were you able to turn them off? Just curious as I've got one on order, and that would get extremely annoying.

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.

As a former GM fan boy. I hope this 2.7l is as good as promised

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.

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.

YES. Give us all the content. We love it.

This engineer is responsible for the design of this super cool engine and he’s rocking a Seiko SKX009. Love it.

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

Crazy that these boys have finally found out high boost small aluminum block engines and hybrid tech after a lengthy Honda deal👀

I swear; at the rate we're heading, everyone is going to be driving semi trucks with 4000 hp 4 cylinders

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.

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.

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.

Props to Kevin for wearing a Seiko SKX!!! 1:00

Very very smart choice for video. I was looking for this explanation for the engine. To compare with Taco. Thanks

Excellent video! Thank you for the info

They will be awesome till the warranty expires!

"We focused on value" - Kevin Luchansky, Assistant Chief Engineer at GM Great, this motor won't last.

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.

Nice job on the interview.

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.

I'll stick with a NA V8 thank you. Good video quality as always SG

Cool package. That said, seeing those Multimatics with the leaf spring is a trip

love the music in this one, very calming

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.

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.

This videos make this channel different, thank you.

Awesome car, awesome review. Thumbs up guys, as always.

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.

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.

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 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.
