I now have 2 of these 2.7 HO engines in GMC sierra 1/2 ton pickups. Very pleased with how they are performing. These make so much torque down low that they do not have to spin as fast as most 4 cylinder motors. Even at 80 mph they turn under 2000 rpm.

Amen

[@andrewsbbq]

Really they cant account for that and is why engine lawsuits get thrown out. There are so many variables that they can't, and shouldn't, need to account for. That's why they have manuals, oil change intervals, oil life monitors, and specified fluids. They aren't responsible if someone pours honey in the engine. It's why GM spends boat loads on having its own 'Dexos' oil specification that oil manufacturers need to meet, and continue to update it.

[@TheFlooringInspector82]

I hear what you're saying, but take this however you want. I own a fleet of silverados with the 2.7. Six of them are 2019 models with well over 100K miles. I like to think that we maintain them fairly well but I can promise that we do not get every oil change done on time and the people I have driving them I already know are not the easiest on the equipment. We have had zero break downs on any of the 2.7 trucks in 4 years aside from one truck that lost the rear end at around 45,000 miles.

I hope they did a better job with the timing chain on this engine than they did with the 3.6 . The engineer describing it as a bicycle chain does not fill me with confidence

[@craigquann]

The problem with the chains in the 3.6 isn't the chains themselves. It's the bullshit long oil change intervals. It leaves too much dirt in the oil for too long. It gets between the links of the chain and chews the shit out of them. Want to trade on every 5 years or lease, save money on oil and do what's "recommended" want it to last, change it earlier and often. Oil is still cheaper than an engine

[@johnseavey6622]

I thought it looked quite light duty from my vantage point

I think because it appears to be a very well thought design. This engineer has allot vested in this motor. He is pretty proud of it. GM probably wants to reduce fears of "turbos blowing up". And the negative perceptions that people have about them. That's why he stressed all the engineering make it reliable. Like keeping the coolant running through turbo at idle etc..

Every new piece of information I see about this truck makes me want to write it off or write a check. It's a hugely polarizing vehicle to me just in terms of my opinion of it in a way I haven't experienced since I first got into cars years ago. I really can't wait to find out about the real world fuel efficiency and performance. Nissan could get my money tomorrow if they'd drop the 5.6 in the Frontier, but until then I have to go through this anguish with the Colorado haha

[@HiPlains1]

IMO, Nissan should have also used a 4 banger with induction. They will never drop the 5.6 into it. And the only way your going to get decent low end torque and still have decent MPG's is with induction. Or a combination of that and hybrid which is what the next tacoma will be. Nissan will likely rot with their aged design for another decade. GM has been fine turning this 2.7 for over 4 years. I think its a little out of place in the silverado but its likely a perfect match with the Colorado which is over 500 lbs lighter. People average about 20 mpg's with the full size. If your heavy on the petal turbos will suck it up. They are all like that. But I can see this getting 25 mpg's or better on the interstate. Some claim this already on the full size.

[@stevenhugley4025]

[@chrishensley6745]

Yep!

[@cgatito3528]

I bet he wishes he could take back the bicycle chain statement. lol. He should have said motorcycle chain. That would've been much better.

[@petergripping1440]

It's at least a triple maybe quad chain. I have seem much smaller

[@lewiswatchorn7239]

I’m a bit disappointed they didn’t add secondary port injection to help with the carbon deposits on the intake valves, especially considering how much they were focused on the three step cams, which only actuate the valves. A catch can is a must add, first thing. Other than that, I haven’t read anything bad about this engine since it came out and it seems even better suited to the Colorados and Canyons. DFM/AFM on their V8s seem to always have lifter failure issues and an oil consumption problem and I haven’t seen or heard of that issue on this engine-perhaps the overhead cams and omission of the lifters is required to get DFM/AFM to work correctly and maybe that’s what GM is working on with their new V8s?? They already have the basis for it in their C8 Z06 Corvette engine.

[@ScotDouglas]

There's an oil separator in the back of the head, no need for a catch can. As far as the AFM - this engine uses mechanical actuators mounted on the cam cover to actually slide the sleeved lobe pack to a different lift profile.

[@lewiswatchorn7239]

@@ScotDouglas I was aware of the mechanical cam actuators, which is why I mentioned using DOHC in the V8s as a way to get away from the problems of the lifters. I did not know about the air/oil separator. Has it always been there or did they add that when they did the mods that boosted the power? Does it send the oil back to the oil pan?

[@griemakr]

@@lewiswatchorn7239 Yes, oil back to the pan. The 2.7 has had it since the beginning in 2019/18 (Did Cadillac get this engine first?)

[@dutch4117]

@@griemakr I know they patented it in 2016, not sure which engines got it first.

Nice work.. Great interview

[@danielguadian2716]

I'm currently in a Silverado LTZ 5.3L. I'm due for a new truck in June. I had many concerns putting a 4 banger in a truck. However, after watching this vid I can say that almost all of them are gone. I like how that 2.7L is overbuilt, use some diesel technology, etc. I just wish that they would also mate the 10speed tyranny to the 2.7L, not just the eight. I'm really leaning to the 2.7L now.

[@byronorellana6886]

GM, please add a robust hybridized version of this engine. I think it would be a great option for us who are not ready to go EV yet. Oh, and make it crate engine available. So many possibilities...

[@LifeBeginsOnTheWater]

Great content & information. The motor looks & sounds like it’s pretty amazing for it’s size. Thanks for sharing! Billy D

[@Murman1973..]

Thanks for the video. Have to test drive one of these engines

[@great0789]

This is what I NEEDED to get interested in this new truck/engine. I have the 18 Colorado with the V6 and we have loved it so much we want to make it our second vehicle. A family of them! I will now read into the new truck some more. I was debating on whether or not to get another old one before they go away.

[@user-FishermanRick]

The 2.7 might be great for a swap where engine room is tight but I like that 4.3 better. For years I'd Google LS V-6 and got nothing which sucked because it's perfect. Now I know all I had to do was search for V-6 LT. Probably weighs close to the turbo, intercooled 2.7 with a whole lot less to go wrong.

[@old-corvair-guy]

Will this be a head gasket eater like the q-4 years back? I remember same test given back then. Will it drop valve seats like the 140( another high heat engine)?

[@TREVORJB101]

Great questions Andre!!!

[@professor_farnsworth]

I have this engine in the HO configuration on my 23 Colorado. I've only got 3200 miles on it but I'm very happy with the engine thus far.

[@garett2892]

Me too man it’s a beast.

[@hfarms5779]

Just purchased a Silverado with this engine. What sold me was an impressive test drive but the engineering, construction and thought put into this engine, gives me confidence.

[@jameshenry3530]

This engine was a natural fit for the smaller size trucks from its introduction. I never understood why it was limited to the full-size trucks. By the way, I never understood why the term for the Colorado is mid-size. There is no smaller size truck; so the size is really not mid-size.

[@frankap55]

Yes there is a smaller size truck segment (Hyundai SantaCruz, Ford Maverick). In that segment GM has the new Chevy Montana.

[@robertmart7123]

Very impressive explanation of the workings of this engine by a great engineering genius... Thanks, Kevin

[@craigquann]

I'm impressed with how much went into this engine.

[@Mdan7]

Some of my questions: What performance change if any running premium? What was the OCI on the test engine? How many 4 to 2 to 4 cylinder cycles were completed in the test run over how many runtime hours? What is the EPA fuel economy improvement due to the cylinder deactivation? Were 4 bolt crankshaft mains considered given the high power output?

[@Don2264]

Excellent questions

[@jamestaylor8951]

I watched another video with the engineer and he said it's calibrated for 87 octane. Premium would be just wasting money. Just need to use good quality tier 1 87.

[@kristopherlauro4327]

On a side note, I remember about 10 years ago when Ford introduced a boosted V6 engine into their truck known as the EcoBoost. They got a lot of hate for it. A decade later, I see GM and Chrysler..or Fiat...or Daimler..or cerebras... Or stelantis - whoever they are doing the same thing now.

[@HiPlains1]

I also remember the first Eco's has problems as well. There was a reason for the hate. But they did improve on the design.

[@nickking1510]

I have a 3.5 eco boost 2011 f150 . Has 380000km on the engine purchased it from a guy who bought it new and changed oil and filter every 5000 km . The 3.5 has never been opened and spray the intake with combustion chamber cleaned couple times per year and clean the throttle body . The F150 runs sound like new with continued 5000-5500 km synthetic oil changes and premium oil filters

[@vettle1]

​@@nickking1510 I'm at 150K miles on my 2012 3.5 eco.... Still going strong also.

[@ppvfd121]

A very well thought out design. Time will tell how long it will live, but I think it’s safe to say this one is gonna be around for a while.

[@mrnibael]

Andre is the best truck reviewer. good job 👍

[@paulbrinker482]

Andre, did you ask how many miles their test is simulating? He said lifetime but never a mileage estimate…. Also love that because of the dual overhead cam the camshaft can be used for cylinder deactivation vs the lifter design in the v8’s! Hopefully the new v8 uses a 4 cam setup…

[@kenyongillespie8652]

I’ve always wondered how the cylinder deactivation works. Loved this video! Never realized how much the stress/heat the turbo puts on the engine. Great video!

[@phild9813]

Yeah, that’s why all the old guys have disparaged all these new mini-displacement forced induction engines for reliability and long term off roading. There’s a reason why the heavy duty gas trucks had gigantic low horsepower engines, a la the big GM 454s and Ford 460s.

[@TFLnow]

Thank you for watching.

[@GreatLakesLogger]

That only applies to the four cylinder to be clear. The v8's use a collapsible lifter to achieve cylinder deactivation

[@nrken1]

Very informative, thanks!

[@GRAFHC]

Excellent video... you can tell he knows his stuff and is very proud of his work. Who knows what these engines will be doing in 10 years, or if they're all timebombs, but it's obvious for a contemporary 4 cylinder this is about as advanced and power as you can get.

[@mdubiansky603]

This was fascinating, I really enjoyed it. I’d be interested to know why they went with 2 bolt main bearing caps when all the V8s and the 3.6 V6 all use the cross-bolted main caps with 6 bolts.

[@grantm1891]

V6s and V8s have less caps per cylinder and put the bearings under load from angles 60 and 90 degrees apart. An indestructible 2J only has two bolt caps too

[@andyharman3022]

What Grant said. Main bearing load in an L-type engine is strictly vertical, so cross-bolting is not necessary. Look at heavy duty L-6 diesels. Most of them are 2-bolt.

[@mdubiansky603]

@@andyharman3022 Interesting. I guess I've never had anything like that apart or watched vids on those powerplants. Good to know, thanks.

Fantastic deep dive review. I was already impressed with this engine's capabilities, but it is truly impressive how integral the engineering and technology is. The world class components speaks volumes and is no wonder why it is already a proven engine since 2019 and improved with each succession.

[@jeffreyjohnston6843]

it's good that they test the motor the way they do and sounds like it's going to be a good one, but you never know how it will perform until its 5 to 8 yrs. old and has gone through winters and summers that will test the longevity of the metals. I still like the sound of a 6 or 8 over its a 4 cylinder.
