I hope everyone had a good weekend. I have to say when I was doing research on this 2.7L inline 4 turbo charged engine from GM I was a little shocked with the amount of technology shoved inside it! Made for a longer video but hopefully you guys like it
so for starters this engine is making a tremendous amount of torque at 430 which to me is wild out of a 4 cylinder turbo charged engine.
the first thing I really liked about this gmc sierra 1500 2.7L turbo is how large the stroke of the engine is. the stroke is just over 4 inches which is larger then the 6.6L Duramax diesel. and having a long stroke really helps to create torque and create torque low in the rpm bands. perfect for towing and pulling heavy loads.
the second thing I like is that GM mounted this engine longitudinally meaning that the turbo piping is very simple. exhaust of passenger side and intake of driver side.
the third thing I like about this is the drivability, this engine does drive very well and the power delivery and throttle response are very good. GM did a good job really setting this engine up elimination almost all turbo lag.
the first common issue is lifter failures with this 2.7L turbo charged engine most like attributed to the active fuel management system from gm.
the second most common issue has to do with the direct injection fuel system. the result is carbon build up on the intake and the intake valves causing less air flow to get into the engine. this can cause loss of power, misfires and rough idling.
the third issues I chat about is the fuel economy. long story short this engine should be getting much better fuel economy then people are seeing. to me if you can't get amazing fuel economy out of the 4 cylinder engine what is the point of even having this engine. GM's own 5.3L v8 gets better highway fuel mileage.
and the fourth concern I have with this engine is all the new technology shoved into this engine could result in less reliability and longevity then a simply naturally asperated v8
I hope you guys liked the video!

My 2021 Silverado has the 2.7 turbo. I've had no problems. I was able to get the regular cab with a long box for $37K brand new from a dealership. It's my first new truck and also my first full sized truck.
you havent had it long enough, they generraly go out at 100,00 miles i work for bakersville chevy and i see em all day long!
Over 50,000 miles still no problems. 1 year.
@@moveitback1sure you do…..😂😂😂
I have a 2020 f150 2.7l v6
What gas are you using?
I have at least one thing in common with that engine: we both have a long stroke.
Ok, I'm sorry. I couldn’t pass that up
GM should build an inline 6 version of this engine. 400 hp and 600tq on 87 octane mated to a 10 speed would be interesting. Probably not that great of fuel economy though.
probably would have very similar fuel mileage to this engine. but I agree you could make some serious power out of an inline 6.
Now your talking...the 4.3 V6 back in the day was a dandy with a 5 speed manual.
Who cares... Make a true HD gas engine with some actual power and no diesel after treatment. Cummins is for RAM, GM is usually behind on everything.
GM was in fact working on an inline 6 engine family, they recently announced its cancelation. I heard this report on Autoline, an automotive news channel here on RUclips
@@twotrackjack2260 sadness...
OHC engines don't have push rods or lifters. The issue with the AFM on the GM V8s and V6s is primarily due to failed lifters.
Some ohc engines have lifters
I like the turbo sound. H.P. and torque are impressive. Thanks for this share I've been wondering about this one. Nice to hear from an expert.
I appreciate the comments made in the video. These primarily sound like concerns you have with architecture being used rather than empirical issues specific to this engine.
I owned the original 2.7T in a 2019 Silverado for 3 years (LT package but used for work truck). I put 147,000 miles on it and it ran exceptionally great. No issues at all. Literally changed the oil every 7,000 miles and that’s it. Maybe it’s because I put the miles on so quickly but I was impressed with this engine. The 8 speed not so much, therefore I now have the 10 speed with the 5.3 👍
engine wear and tear is all about the heat cycles. highway driving is better then city driving
Are you getting good fuel numbers with the 5.3? Happy with the 5.3 compared to 2.7?
@@brianonthego it’s nearly identical to the 2.7 in my experience. Both trucks had/have a leveling kit and 275/70/17 tires. Overall average is 19-20. You can easily get 23-25 on the highway but it does drop down to 15-16 sometimes in the city. It’s truly impressive between 35-65 mph but above that it takes a dive. 49K on it right now and not a single issue.
What kind of climate do you live in?
@@phillipcotten4872 What kind of climate do you live in? Turbos where I live usually burn out quickly since we hit temperatures above 120°F
I've owned one since 2021 Memorial Day weekend. So far I have 71000+ miles on it and no issues. I generally get over 23mpg with it on the highway and about 20mpg with just regular driving. When I pull my landscape trailer the mileage goes down to about 15 or so. The trailer has a High gate on the back that creates a lot of wind resistance. We'll see how it goes from here!
If you're lucky, the problems may not occur until after 100k
Finally someone puts MPG while pulling something relatable. You my friend win the internet today!!
Damn that's impressive! No problems whatsoever?? I bought a brand 🆕 Tacoma TRD off-road & I had to take it to the dealer because the front diff actuator broke (or never worked) & got stuck in 4X4 & my AC didn't work from the 🏭 factory... i live in PHX so that sucked it was 120° & had to wait a week to get it fixed
@@k.lindsey3529Their are videos out their with over 160k miles, zero issues! 😐
@@honda116969I live in Phoenix also and my 2022 Tacomas ac heater blower fan self destructed and fans blades came off, no AC either and happened in august ,,,,this happened at 500 miles, payed that truck off and traded it for a new Colorado Trail Boss, I love this truck it’s a little beast! I got it calibrated to 430# torque too!
I just bought a '23 Silverado 2.7. It has gobs of torque down low where a truck needs it. It feels very utilitarian, but that's what I wanted.
The actual head engineer that helped developed this engine says that this motor was designed to run on 87 octane and not premium. In this day and age I still can't believe the amount of people that still believe running higher than recommended octane in your car or truck will increase performance or gas mileage. If it's designed to run on 87 you're gaining nothing by running premium. 🤦
Not all engines, but some motors do actually gain performance with higher octane. We had an Acura that plainly stated in the owner's manual that fact.

@@mikesamson1930 - Yeah, if it is stated in the owner's manual, then it's real. Otherwise, what the engineers said.
It is my understanding that many engines retard/advance timing based on the knock sensor feedback. Octane should allow more advanced timing, leading to more HP. What am I missing?? @@randolfo1265
There are a number of manufactures that clearly state different outputs depending on octane. Obviously you are ignorant to that fact.
Great video Alex - man, you nailed it when you said there are a lot of complex systems and active components that have the potential to breakdown - hopefully GM can iron out the failures/issues in what I think is pretty neat technology -
You’re back in ON again?! Welcome, thanks and cheers
Erated -78 I do not recommend buying GM stock. They build expensive heavy pickups that run on 2 cylinders and those powered with electric motors.
Very informative video sir! I bought my 2019 Silverado 2.7 in December of same year. I got a screamin deal, (probably because a lot of people were scared of it! 😮) so I purchased an extended warranty. The most heavy thing I tow is my motorcycle. So far at about 44,000 miles it has been good.
I just purchased a 2024 with the 2.7 I4 I appreciate the knowledge you was given, I’ll definitely keep you updated on the results as I go
how is it so far? i plan on getting one soon due to affordability out of the rest of the engine selections

I just purchased a 2024 GMC truck with 2.7 turbo I think I will get over 200k they make great trucks, my last two GMC trucks I got over 200k miles they had the V8 I’m staying positive on this engine.
i'm worried that all that tech will need a lot of repairs throughout the years. knowing how much the turbos depend on clean oil, i would get oil changes more often than suggested
@@topherh5093you should check the road test Chevy did. B3st engine they've made longevity-wise since the vette 80s v8
I’ve been waiting on a review of this engine for some time thanks.
A 3.5L inline six would be nice. Basically a modernized 216 ci. that was used successfully for decades. Well balanced and tough, a good platform to build on.
5 cyl turbo sounds > 4 cyl turbo sounds.
Wasn’t the 4.2 a good motor?
@@captinhoopit is
@@captinhoopVery good, but discontinued due to engine length being a problem in crash tests.
6 Cyl are smooth too.
Another great review. I had 100k before trading it in. I found the truck to be very light and didn't have balls when passing semi trucks. But it passed all the work tasks.
fair enough! what did you trade in for?
Trade in for v8 chevy the redesign. I have two
@@michaelpanacheese604 how was the mpg on hwy?
I'm rocking the 8.1 in my 05 suburban, I'm at 316k miles and still going strong.
The 8.1l engine was great for its time. The new 6.6L gas HD engine actually makes more horsepower and torque than the 8.1L while getting significantly better mpg while doing it.
Anecdotal but here’s my feedback after owning it for two years. It’s been nothing but reliable and I like the way it drives better than the other engines as well. I live in colorado and regularly drive it at freeway speeds at high elevation with dirt bikes, mountain bikes, kayaks, landscaping material and equipment, etc. I don’t tow boats or heavy trailers, neither do most truck owners. For the average full size truck driver that wants a large cab and a good sized bed, it’s a great truck. Go buy your diesel if you tow boats up mountains. Or if you just drive it to work and your kids soccer practice, but you want to pretend you tow a lot. For the rest, this seems like a great truck so far. Maybe I’ll be proven wrong in the future. We’ll see, but after two years of owning it I couldn’t be happier.
Wait until your lifter collapses.
@@sabastian4858 did that happen to you?
I think it's overhead cam, not pushrod.
2 years is nothing, 4 out of 100 catastrophically failing is crazy.
@@GeorgeL.3 4 out of 100? Is that a fact? Mine is still perfect. We’ll see if it stays that way.
The injector on my 2022 Silverado failed at 14k miles in the middle of nowhere TX. 40 days later GM is still working to get the truck up and running. The current GM tech recommendation to the dealer working on this is to circumvent the wiring harness and plug directly into the ECM - quality build...
Impressive numbers. Great truck to have while it is in warranty. Not the one to own 15 years from now.
So, basically you have one and have a lot of personal experience with this truck and motor?
Not to own after 3/36. If it is so great they should warranty it to 100k miles
Theres talk that they are going to change the warranty on the 2.7 to 100k based on how successful its been in having very few issues .Also because of peoples hesitation
Ford's 4 cylinder ecoboost engines aren't the best, but the v6 ecoboosts have proven themselves to be long-lasting when you dont neglect oil changes. I've seen dozens of 3.5 ecoboost f150s with over 250k miles. Ford's v6 ecoboosts have forged internals, hypereutetic pistons, 6-bolt mains, and beefy piston rings.
If GM built their 2.7 to similar durability standards, it should be able to go 250k+ miles with proper maintenance. Turbos and smaller displacement do not automatically mean poor longevity. It's all about how the engine was built. Diesels run higher compression and 10-20psi more boost.
Well I’m 15 years slap a 6.2 or 5.3 in it…. You’ll still be up $ from
The 5k up charge on a new v8
Thank you for the excellent video and analysis. It was very educational. 2.7 will need some time before we can really make a conclusion as to whether it's a good engine or not. It seems like it might be more suited to the suv/mid-size truck models. I always wondered why GM wouldn't have tried to make their historic 4.3 V6 into a turbo engine. I think that would have been more readily accepted by the public.
I’m a V 8 kinda Guy 😎🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
No 4.3 due to emissions. Same goes for the 4.0 AMC/Jeep straight 6. Same reason why this turbo 4 exists, emissions.
The government ruins most everything.
@@bannedbycommieyoutube5time920 Have you ever been to Bangkok? Thailand has little to no emissions standards and the air quality is horrendous. With that being said, I don't agree with everything the government is doing in regards to air pollution, but we need to find a balance between emissions standards and practicality.
GM did make a 4.3 turbo - GMC Syclone.
@@SD-pi9co just like everything else, common sense tells us some regulations are necessary. US air quality was mostly cleaned up by the early 90’s.
At a certain point, you get diminishing returns, the juice is not worth the squeeze. The engines I mentioned were not creating anything remotely close to 1960’s urban air or current air quality in Bangkok. From a practical perspective, the air quality was fine when these engines were in place.
Another item is diesel engines, which have unreliable emissions equipment including DEF, EGRs that increase EGTs, among other systems that are horrifically expensive to fix. Most people don’t care, but they don’t realize EVERYTHING gets moved by diesel trucks in the US. When diesel trucks don’t last as long and have far more expensive and frequent maintenance/repairs, the cost of EVERYTHING goes up as a result.
I get 18ish around town (casual) driving and 24mpg when I took a road trip (all highway) the end of last year. The 2.7HO is one of my favorite engines and I got it "kicking and screaming". It was a budget decision and it has been great after a year. Even better than my previous 3- 5.3's!
As other commenters have mentioned, there are quite a few videos interviewing the engineers…one thing they discussed was the active fuel management system. I agree that GM’s previous AFM system was trash, but they also stated that they moved away from the hydraulic system in this motor and moved to an electric system instead, supposedly eliminating the lifter/valve issues seen in the hydraulic system. I would be very curious to hear your take on that system! Thanks as always for another excellent video!
Alex Yes this motor has a lot of Tech in it. But you might want to look at the internals of the L3b before making a blanket statement about AFM lifters failing like the v-8 versions. This engine is DOHC that uses camshaft follower and hydraulic lash adjusters. Nothing in this engine is like the AFM lifters/system in the 5.3/6.2.
I Imagine the AFM is a different set up in this engine based up the 3 phase cam shaft. but a cam followers or a lifter does the same thing more or less. the v8's are all hydraulically adjusted as well. It's no secret that the 4 cylinder engines are having valve train failures. weather it's directly related to the AFM system that could be a debate but something is causing these issues.
The valve train aside from AFM is a nightmare. This build will not withstand high mileage. I have yet to see even one of these motors push past 200k. 3 phase camshaft, no thanks. Its junk!
@@sabastian4858one for sale near me with 180k on the clock and nothing but oil, tires and brakes on the service history. I see a few listed over 200k miles, but it’s only been out since 2019 and I don’t see many 200k 5.3s from 2019+ either.
Guess I’ll stick with my ‘00 GMC 1500 Z71 with 180,000 mi. I know of some with 3 and 4 hundred thousand with no engine issues. Of course they’re dinosaurs compared to new stuff
@@Gracies_vlogsI have an 08 with the 4.8....I have 296,000 miles on it
Great analysis on the L3B. I've been considering a new Colorado or Canyon and have had some serious questions about this engine. This is going to be a retirement truck for me, so I'm looking for something reliable. I love the styling on the new Chev / GM mid-size pickups, but this complex new turbo 4 banger is giving me the willy's!! Thanks for the honest answers and opinion!!
I like my 2015 have had it 8 years.
But I'm very skeptical of the new models Esp. because of the new 4 cylinder.2.7
I will have to see how this new model pans out. (the new Canyon) You can only get it in 4 cyl.Turbo. Don't like that!!
Too new. $40K - 65K (TOO MUCH)
You are not the only one skeptical about that new engine. (2.7) I am scared of it also. 😳
Half as many bearings, rings, valves, and heads to go bad. The transmission is the weak point
I feel like it's a trap. Prices continue to grow and reliability gets worse.
You are not alone on the durability of the 2.7 Gm turbo engine.
I dont think that they will last long.
Im driving one of these right now it a Chevy. I gotta say I love it so far. I have always had a 5.3 but this had a sweet lease on it. I have pulled the goose decoy trailer I use for goose hunting it a tandem cargo trailer with shelves and a ton of decoys and blinds absolutely no problem at all.
This was the answer I was looking for. Did you have any issues with the trailer in mud or fields?
I have a 2022 GMC 3500. With a 6.6. Welder , 100 gal fuel tank and big tool box in the back all the time and I’m getting 16 mpg and never on a highway. All secondary roads. I love it…….. so far. Only have 15 k on it.
Pickup Truck plus talk just did a great live video with the Gm engineer of the 2.7. Was impressive
Yes saw it and that engineer who designed this engine emphasized it is designed for 87 octane and going higher is throwing away your money.
Agreed! It’s a great video and explains the technology and the incredible reliability of this motor. It sure looks like most commenters to this video have not watched the video.
Love this engine.. the sound and the torque. I love 4 cyl turbos though. I got surprisingly good fuel economy versus the v8 I rented and it felt faster off the line. But you’re right it is a complex and new engine. I bet gm will make it great over the next couple of generations.
Tell us how much you love it after spending 60 grand and it explodes in 3 years.
@@pcmountaindog 40k cash w/ 8k miles. We'll see--I trust gm's engineers over YT commenters, but do expect a bit more maintenance.
@@fabbritechnology Don't you know YT commenters know everything and are the best mechanics? I'm sure many of them have at least 3 years of experience turning wrenches. There's no chance their comments are a result of insecure man-boy knee jerk reactions to - gasp - a smaller but highly capable engine. Most have probably never seen a 4 barrel carb and wouldn't remember how every mechanic said fuel injection will never last.
I’m looking to buy a new Chevy/GMC pick up and had a lot of questions about which engine to get in whatever one I purchase and the 5.3 review as well as this one were very helpful. I’m definitely leaning toward the 5.3. Thanks for the thorough review.
RUN from the 5.3 ...lifter issues ! ever since 2007! good job GM !
Thank you sir for pointing out past flaws, along with the innovations. That sort of insight is sorely lacking on most other reviews of the 2.7. An engine that I doubt will still be running and driving in fifteen years like we expect the V8’s to be.
Why do you doubt the engine longevity? What are you heading your opinion on?
@@5zwoodworks Been a professional mechanic since 1987 and counting. My past experience with small displacement, GM, turbo, gasoline engines, ain’t one of high opinion. So, taking that experience, I base my opinion of future small displacement, GM, turbo, gasoline engines
You can expect a modern V8 to be running in 15 years but you would be mistaken 😂
@@5zwoodworksIt’s complexity. Didn’t you watch the video?
@@andysteward8617Exactly. I wouldn’t touch a modern engine. I’ll suffer the low gas mileage and lack of power for longevity and cost of maintenance any day.
Be kind of cool to have this as a crate engine in both FWD and RWD APPLICATIONS.
My powerboost gets about 11 - 11.8 l/100 in city and between 9 - 10.2 l/100 on the highway. 2021 f150 long box crew cab lariat high on 35" x 11.50 wildpeaks. I lost a bit with the AT tires, but its still better than any truck i've had in the past.
Had four 5.3's in 1500's over the years. They were fine. Finding a tech even at the dealer that will be able to troubleshoot the 2.7 would be a worry. My 5.3's always got 16+ mpg and didn't shutdown any cylinders. My brother took his High Country with the 6.2 on vacation and said he got 26 mpg on the highway. Heck, even my 2011 vette gets 26 mpg on the highway.
I have a 2020 Silverado with this engine in it and so far I like it a lot for it being a 4-cylinder in a big truck. I have had issues with mine but it has all been failing sensors and other plastic computer junk which have been replaced for free under warranty. I haven't had any mechanical issues so far, but there also isn't much mileage on it due to it being a lease vehicle. When I first got it in August of 2020 I was originally running high-octane gas in it as the norm up until the gas prices skyrocketed. Now I just run normal 87 and top up the tank every Friday so I don't have to buy as much. I'm sure adding an octane booster into the tank would help for less than buying high-test fuel.
As for engine longevity I do my best to buy the best engine oil I can get my hands on. Since my mileage is extremely low I'm only on my second oil change. The first oil change was done at the dealer to take advantage of a free oil change. But when it came time to do a second oil change I was happy because the ACDelco oil they use is crap. The engine felt like it didn't rev clean when I was driving around. With the second oil change I bought some full synthetic STP and it runs much smoother than it did with the ACDelco junk in it. When the third oil change comes around I'll be switching back over to the Royal Purple I've been running in my previous truck. From what I read on RP's website the stuff I was previously running is formulated for newer aged vehicles as wall as those with turbo's. So that might help with longevity.
As for current gen 5.3's I will have to disagree with them being good engines. Which hurts me to say as the 5.3 is one of my fave GM engines besides the 327. The 3rd Gen 5.3 out of my previous 2004 Silverado was a great engine with minimal problems. After 2005 when they started going ham with the AFM rubbish the 5.3 stopped being good in a stock config.
You really don’t want to switch different oils like, or change to different octanes. Pick one and stick too it. I would just run 87 in it, and out additive every 7500.
@@calebniederhofer6529 If it was ran for 100K miles on nothing but conventional oil then switching oils would be a no no due to worn seals and what not. But since it has less than 15K miles on it and nothing but synthetic gets ran in it switching oil isn't going to bother it.
Especially since you can't control what a dealership puts in it when a family member tells you to take advantage of a first free oil change. And to be honest it's a modern turbo'd engine with tighter tolerances so it shouldn't even have conventional ran in it in the first place.
I run AmsOil and Royal Purple in my vehicles, if I run anything else it's because I don't have the money for my normal choices at the time and I get the next best thing that isn't as costly. Switching oil is better than no oil changes at all.
So far it has only had two oil changes done to it and the third is coming up soon so it's getting Royal Purple this time around and will continue to get it there after.
For those who are unaware- the new Canyons and Colorados are now equipped with the 2.7l turbo four. The 3.6l V6 and 2.8 Duramax diesel have sadly both been retired, so it’s the only engine available but it comes in different states of tune. It seems like a good fit for the mid-size trucks with a better power to weight ratio than in the full size trucks. But, in my opinion the 3.6l was a great fit too, fairly bullet proof, plenty of power and the fuel economy was nearly identical to what these new four bangers are getting. I’m just guessing but maybe GM wanted to advance the technology and increase low end torque? But it’s just not really an efficient power plant either so it remains a mystery why THIS is the future?
Epa regs.
the 3.6 v6 is fucking garbage
The 2019 2.7 sliverado pickup I had avg'd a hand calculated 24mpg per tank. Other then a diesel with Def, there really isn't a a better mpg out of any of these newer powertrains. I can only hope a colorado/canyon would be more efficient.
It only comes in different power levels(3 of them) in the 2023 colorado. The 2023 canyon only gets the full power 310hp 430 torque version of the 2.7T.
@@troyg3439 the ZR2 colorado comes with the high output engine
At 10k miles on my 2023, dealership has seen it more of its life than I have so far. It’s driving mostly ok as of now, just a small coolant leak somewhere around the radiator but have had the entire fuel system replaced including high pressure fuel pump and a total of 9 ECM replacements. Next time it breaks down it falls under the lemon law, fingers crossed.
Great vid with valid points. I think it comes down to what you use your truck for. I currently own a 2011 sierra with the 5.3 and its still a great truck but with me now towing less weight here and there I am very interested in one of these 2.7 turbos. I’ve also been looking into the inline 6 turbo Duramax. My issue with going diesel is the higher price at the pumps. I don’t put a lot of miles on my truck to benefit better fuel economy with a higher price tag. That being said maybe I should just stick with the reliable 5.3 V8. Thanks for the in depth review of this engine!
Disable the AFM/DOD if equipped and get the engine converted to a non afm/dod cam/lifters.
Electric water pump to me sounds like a motor winding failing without notice.
Alex ,I'm a Ford guy,and I've owned several high mileage Ecoboost engines.I will never ever go back to a v8.If I was buying GM I'd select this engine.The 5.3 has not been without problems if you look you will find them.I know many that have this engine and are more than happy with it.Pulls incredibly well.Im also looking forward to Ram's new Hurricane turbo engine.Run Supreme fuel,use synthetic oil and change it well before the oil life monitor tells you, and an occasional wide open Throttle, and any turbo engine will reward you with many miles
The 5.3 is extremely famous for a reason, and swapped into everything made. Only consistent problem I've seen is those crappy intakes, 250 bucks if you DIY the repair.
@@wymple09you are referring to the LS/ vortec variant of the 5.3 which were amazing. The LT variant of the 5.3 which has been around over a decade is a massive turd with lots of problems.
What a soyboy comment lmao
What blows me away about most GDI engines these days is how few of them have gone with dual injection to clean the intake tract. Ford seems to be one of the few to do this - like on my '19 F150 2.7L. I'll probably go 3x further before having to consider walnut blasting.
My 2023 Tacoma V6 has the dual injection “D4S” system as well.
Ford and Toyota are all in in spilt injection. Ford and Toyota have something in common. They are > than GM
You don’t need that with a proper oil-air separator. The wife’s LGX doesn’t have a lick of oil in the intake where my LS3 loves sucking up oil.
@@IVloses Oil in the intake isn’t the only problem, it’s the lack of cleaning action from moving the fuel injector post intake valve.
1. Even a good oil separator doesn’t remove *all* oil vapor/droplets from the intake tract and carbon deposits come from open valve reversion, valve stem seal/guide leakage *and* PCV oil deposits.
Split port injection is the only sure fire way to eliminate carbon building on the intake valve with GDI.
The other band aids aren’t true solutions
@@IVloses I also installed a can on my wife's Palisade with GDI, and it does a great job of removing lots of gnarly crud from the intake system, but like our friend "B C" comments here, I know this is only an aid, not a cure.
the MPG dropped with the HO 2.7L. the 350 ft pounds on 2020 with an upgraded air filter/plenum boosts very nicely. I run 87 with lucas fuel cleaner in every tank since new and the motor purrrs. usually 19mpg at 82mph cruise. mine is 4wd, 19 2wd mode, 18mpg AWD mode. it picks up and moves, no performance issues - had it 60k miles and I love it. also has airflow shutters on the low-mounted-on-its-own intercooler (the bottom grill). Only downside is going offroad in florida if swampy water - will submerge lower intercooler shutter system in sandy water, so Ive not used it less than I would have used a 5.3 offroad. around town MPG is more like 21mpg. 2020 model is 87 octane.
Hold the phone! I don't usually like red ...but that truck is sharppppp! Cool Vid, I enjoy your in-depth reviews. 👍
I have 60,000 miles on mine and it is by far the best part of the truck. The 2.7T is a fantastic engine…
It’s funny how most are concerned about the engine, but it’s solid . 4 cyl bias is real lol
@@thomasmcghee2468 , absolutely correct!
@@thomasmcghee2468 Absolutely...you're dealing with semi-neanderthals who are programmed as "V8 is manly and anything less is not manly". Explaining the science behind it is useless.
curious to see how this holds up with fleet drivers !!
T&B Up-North - I think these trucks would be too finicky for fleet use.
I got a 2023 Custom with this engine, i love it
I went from a 2015 gmc 5.3 to the turbo mine is a 22 Chevy 1500. So far no problems at 15000 km. Wish me luck. PS 18 MPG average according to the computer. 🇨🇦
My 2023 Silverado gets between 21-25.5 mpg daily the 2.7 also has 435 ft lbs of torque vs the 5.3’s 380 ft lbs
I gotta say this. I bought one of these a few years ago. It has been great. I was very skeptical and thought it would be a quick trade in. I’ve been driving tacomas for years and planned on getting another one. I rolled the dice on the Silverado 4x4 2.7L. 52k miles later and I’m still averaging 19-21 MPG in town and 24MPG on the HWY with long interstate trips giving me 25-26 MPG on 87 octane fuel. I put some premium stuff in every now and then if the price is low, which is almost never. I also change the oil every 3,500 miles with cheap 5W 30 dexos oil. I do this because you have to keep an eye on oil levels in these Chevy’s that have cylinder cut offs.
My only problem have been I wish it had the smother 10 speed transmission and I wish it sounded like a V8. Hell I don’t even care about the sound anymore. I will probably trade it in a few more years just because that’s what I do. If they still have this engine in a few more years and it continues to hold up I would get it again.
At this point I worry more about the transmission than the engine, but it’s doing fine as it is, just wish it was smoother.
Jesse Sellers - After your experience with this Silverado, what is your opinion of new Tacoma and Tundra?
@@carlcampbell6827 I love the tacomas. Always have. They are solid, but with how much the price has gone up on them versus the smaller size and capacity it’s just hard to justify getting one now. As far as the new tundras I don’t know. They are expensive and I just really like the previous model design over what they have now. I got a good deal on my Chevy Silverado, but the prices have gone up a good deal on them now as well.
I do have a friend who has a 2022 Tundra and out the door his was 70K. He does like it though, but mine was 32K out the door when I bought my 2.7L Silverado.
Real life experience. Thanks
I understand that the Eight Speed has been improved to work much better and now comes with Better Oil to elite Torque Flutter.
They've gotten better with the 10 speed programming but it's taken so much time. Sseems like they added tons more gears without the code to use them correctly. My sister has the v6 atlas with a vw 10 speed and in normal mode it's always searching at low speeds. Seems fine in sport mode.
I sure would like it to see a long term test beginning at zero kms for a ProVent catch can on these direct injected engines. Seems to me, if we remove the wet oil mist from the intake tract leaving only EGR, the valves, turbo, charge air cooler and intake piping would remain clean. The ProVent is the only catch can I know of that is plastic to reduce freezing, has a proper coalescing filter as well as relief vent should it freeze.
Was in the market for a truck back in the fall…looked at full size and all they would have on the lots were these “4 bangers” as my dad lovingly refers to a 4 cylinder…so I started to think about a canyon but 2023 they don’t offer the 6 anymore only this 4 cylinder as well…so I went used 2020 and this video just solidifies my decision to not get one with the 4 banger in it!!
If most viewers ACTUALLY understood how this 2.7 was designed and created, there would be no doubt to its durability and longevity. External waterpump, beefed up internals, stronger block, cooling of turbo independent of engine Temps, etc. This is a very well-thoughtout engine.
You also talk about direct injection which you know is not exclusive to this engine. I believe it's a moot point because it makes it seem like the 2.7 will suffer failure because of a universal fuel delivery designed used in 100's of engines.
I agree with you in that this 2.7 is a well thought out engine. It’s just a shame that it’s matted to 8L90 trans instead of the 10L90.
SLIDING CAM
SHAFTS 😂
Correct. It's useless trying to explain the engineering to closed-minded dolts. They know nothing but "V8 is more betterer and more manly". I'm currently a Hemi owner but am looking into this as I feel it's the way of the world in the coming years.
@@rolandthethompsongunner64 Yeah I said the same thing till I realized Audi does the same thing with their 3.0t very solid motor and the only issue was the “slide points” because I don’t remember what they were were getting beat up and failing because they were too narrow they widened them out to distribute the force better and there hasn’t been issues since. The only thing that worries me is having 3 cam profiles that the engine can switch between actively.
First, this engine doesn't have lifters, and the guy who designed this thing flat-out said it was tuned for 87, and that premium was a waste of money.
I saw the interview where he said exactly that.
I did a road trip rental with a 2022 2.7L 1500. Liked the truck a lot. 18MPG going very easy on smooth roads 45-55 backroads and 65mph highway. Never exceeded the speed limit. Truck returned 19MPG with a tank of 93 octane, on the way back. Which was also downhill a bit (not much more than 1000 feet) back to sea level. Drove in some light snow, no issues what so ever.
I bought my 22 silverado last year 2023 wit 16 miles on it. At the moment I got 4k miles on it, fun to drive, saw it has a plastic-ish oil pan drain bolt and realized the oil pan was plastic-ish. Also has a oil and trans cooler, so good coolant level maintenance is a thing to keep in mind imho. Still love it.
Should’ve used the 4.2 inline 6 from the older trailblazers and turboed them for the truck
Yeah, it's a 166 cubic inch beast. My guess is if you actually try to tow anywhere near 9000 pounds with this engine on a regular basis, it will be on the scrap heap at 60K to 80K miles.
Why would you say that? It's built with better internal materials than the old,should be retired,5.3 v8
So it’s turbocharged. Like diesels. Anything else? Why would it have wear issues? Want to compare reliability to a new diesel?
Owner since 2020 towing 6,800 total payload including passengers. This truck is a absolutely flawless 3 years this month April 22. I have towed now 23K miles and in mountain country out West. I have yet to have an issue. I owned the 5.3 2019 Silverado. Was OK but lower performance then my current 2.7L T. And my fuel milage is better even while towing. My low end torque is masterful in grades! If I had to tow 9K lbs due to work /continually very likely I'd be in a 3/4 ton anyway.
tow numbers are ridiculous at this point. Someone needs to explain the concept of "just because you can doesnt mean you should" to these people.
If you tow on a regular basis you should get a 3/4 ton or the 3.0 diesel. Not everybody tows.
Great info, thank you
Whoot Whoot to the 519.
Keep up the great work!
@11:38 the lifter issue you describe is lifter delamination that occurs in pushrod engines but this engine isn't a pushrod and it doesn't have lifters, it's dual overhead cam.
Cam followers but they perform the same task. they are both hydraulically adjusted and I would imagine the AFM set up is very similar.
@@TheGettyAdventures maybe you're right, you know more about engines than i do since you are an actual mechanic. I just know that class action lawsuit doesn't include the L3B engine and it's been around for 4-5 years now.
By the way i love watching your content. No bullshit, no bias, just the good/bad and great info.
It’s a slider assembly on the camshaft that slides the cam follower from low lift (max fuel economy) to med lift to high lift (max power). No AFM lifters to fail as in a pushrod engine.
I ran both 87 and 93 octane. There was no difference in mileage. I drive it lightly and I have tried to make it better mileage than the 2015 2500 Duramax I had prior to this 2020 2.7.
Plus my 2.7 likes oil. 2 litres between oil changes.
I like the simplicity of the Chevy front end. It’s slightly more sleek too..
Counter balanced inline fours are now new. I don’t think I’ve heard of issues with them and they by far the most common type of I4.
Like your shoutout to Engineering Explained
21:30 "usually simplicity equals reliability and this thing is very far from simple"
I couldn't agree more, so well said.👍👍
Usually the case, I do like that GM is pushing the technology but would I want to pay 60,000 dollars for something unproven, not really.
@@TheGettyAdventures You think if fuel efficiency improved by some 20% then all that tech would be justified?
If hybrids didn't improve MPGs, nobody would want complexity I'm assuming.
Highest mileage I know of with this engine on regular maintenance with no issues is 230k miles.
I have the 2.7l turbo 2 door,2wd 8 foot bed WT and I am getting 22mpg and have no problems! I'm satisfied with it!
That mileage just isn’t that impressive.
I am looking for the same truck. Now that 4 months has passed are you still happy with it? Do you use premium gas or have you tried the 87 octane.
@@mikepeterson8037 I use premium and have no complaints with it!
Got a great deal on a 23 Chevy 4x4 with this engine. Initially apprehensive, I was impressed with how easily this engine drives un-trailered. With a 12' work trailer that weighs ~3k lbs, it requires more pedal to get moving than my previous 5.3 did. After a week, the (memory of the) difference faded away.
This much tech (and the price to fix it) is why I thought an extended warranty would be a good idea...and ive never been an extended warranty kinda guy.
So far, with 2500 miles, my avg fuel mileage (according to the truck which is within .2 mpg of manual calculation when i checked) is just over 17 mpg. That's with city trailer towing, new truck idling while playing with gadgets inside, and a 1200 mi road trip with 78 mph speeds.
-23 Crew cab, 6.5' bed 4x4 is getting better combined mileage than my '17 regular cab long bed 2wd 5.3 truck (the '17 truck was usually 2 mpg off of actual mpg)
Only issues: transmission sometimes clunks down to first gear only after hitting the gas from a stop.
The audio (both fm radio and from audio book from phone) has stopped working 4 or 5 times. A restart of the truck fixed it.
Hope they did better with this 2.7 than the oil burning 2.4 Ecotec. That was such a problem child of an engine.
I had one of the 2.4I. I was a problem on 4 Wheels. ( Junk) js.
I had several 2.4 liters and had zero issues kept them for several 100 thousand miles. It’s all about using good oil and change intervals.
Your definatly right about the tech breaking down. As a GM tech i run a 99 k2500 hd with a 454 gets 14 to 15 hiway on reg fuel. Hp and tourqe numbers between that 2.7 and my 7.4 are near equal but im quite sure that truck wont outpull my 454 and cant get that 2.7 in a 2500 hd so id say GM doesnt think so either. All that technology nothing but headaches that means countless days at dealer for repair and be driving some chevy malabu loaner yippi...ya thanks but no thanks GM
those GMT400 trucks are worth their weight in gold! I used to own a 96 k1500 Z71 with the 350. best truck I ever owned should of never sold it. I appreciate GM trying to move the needle but it's not something I would personally want to own in a pick up truck.
One thing the 2.7 sure won't do compared to the 454 is tow for 100k under boost 60-75% of the time.
If you turbo that 454 you will have some serious power.
Probably the biggest reason why GM doesn’t throw it in their HD trucks is because HD trucks don’t have to meet MPG and emissions goals since they’re unrated. That’s why you have a 6.6 gasser that was mated to a 6l90. Now their 1500s aren’t HD classified and therefor do have to be EPA certified and that’s a major reason why they shoved this engine in it.
@@TheGettyAdventures Those 96 Z71s were nice; would be worth refurbishing. Hell I am still kicking myself for letting go of my 71 Ford F250 heavy duty Camper Special with 360ci.
Can't speak for this engine but with my 2013 f150 ecoboost when I put my tuner i was actually surprised how little it was actually under boost while cruising down the highway most of the time on flat roads its around 3 to 5 psi vacuum and all but one steep hill very rarely goes over 4 psi of boost
I have a 22 1500 Silverado with the 2.7 t it totally impressed never thought I would like it but I love it
Those were the best headlights of 2023 👍 From a Ford guy.
The truck engine is tuned to run on 87 octane. The engine variant in the Cadillac is the version that requires 91 octane.
100% can run 87 octane. But at least I read GM still recommends running 91
GM does have a Premium tune for this engine. unleash the demons!
It can absolutely run on 87 octane, but the knock sensors will decrease your power, and your efficiency...
GM engineers say the truck engine is absolutely tuned for 87 and you are just wasting money on premium fuel. Check out truck and SUV talk , they had engineer on live talking about this.
@@TheGettyAdventures they do not recommend running 91. Max power output is achieved with 87
The reason they are using a 4 cylinder instead of a 6 is material cost savings. There are engineers that spend all there time reducing material. They study making every screw one thread shorter. Or like the ignition locking pin that went horribly wrong when they shaved 1/4 mm. Anyone remember car’s shutting off and causing accidents? GM’s fix, don’t put anything extra on your key chain. So imagine the lustful excitement when they get to get rid of 2 cylinders and blame it on epa smog regulations.
lol I remember the service tech telling me not to put any house keys on the key fob, only the key for the car. I was like, what?
i got the 2023, i love it, LOVE it.
So thankful for your super informative review! Thanks for the fantastic content and pointing out of all the key issues, both positive and negative.
I was originally considering the two 2.7 engines from GM and Ford.
The Ford is obviously a much more proven and simpler design, even though some of these GM innovations on this engine are heading in the right direction.
I have a couple of 2022 GMC 2.7 pickups. 17 mpg city 19 hiway which is Bout 2 mpg better than a 5.3 GMC I have. My 5.7 2019 Ram gets a little better than my 5.3 but not as good of gas mileage as the 2.7. The 2.7 will hold 80 mph at 2000 rpm over mountain passes and never has to downshift due to the massive low range torque. Very smooth power plant that is pretty quick. Crazy that it has more torque than my 6.4 Power Wagon.
No it doesnt
I thought 430 was a bigger number than 429 but Fozzy bear knows better.
How many trucks do you own lol
Too many. 3 Dakotas, and 2 Durango among others. I am a Mopar guy at heart.
what trucks do you NOT own!! wow I love it lol I will say it is a smooth driving engine no issues there.
Great Information. This engine is better suited for GMs midsize suv lineup not a half ton pickup truck. With the cylinder deactivation/ fuel management, history is destined to repeat itself for those old enough to remember Cadillacs 4*6*8* engine.
Chevy should bring back the 4.8L and use that as the base engine and have a lineup of
4.8L, 2.7L, 5.3L, 6.2L, 3.0L
While I agree with you mostly that Cadillac was a long time and before computer controls
I opted for the 6.2l, because that’s what it should have. My Xt4 2022 appears not to have AFM.
I have this engine in my 2023. I have the Sierra 1500 Pro WT. Its a singlecab, 4x4, white, steel wheels, vinyl floors etc. The only upgrade option is chrome bumpers.
Good review i mostly agree with all your points on this truck. But like I always say about GM vehicles they build there vehicle for planned obsolescence and I definitely see that in this truck. I do think the 2.7 has alot of potential but definitely not in a full sized vehicle. And know days probably won't even get there 5.3 option since they poor piston rings problem they're having. GM saying lossing 1 quart of oil every 1000 miles is normal is just stupidly bad
In point of fact GM trucks from 1960 up to 2013 were the very opposite of planned obsolescence. The interchangeability within each generation puts all other makes to shame, and the same extends to a large degree between adjoining generations and even beyond. After 2014 and thx to ever-increasing government abuse things aren't the same...
Some of you guys must live under rocks. Big blocks are slowly going away. The future is these smaller turbos and EV's.
For now I still think it's an abomination. A four-cylinder in a full size pickup. I'll have to wait and see for the $100,000 mi reviews.
Not sure if you read thru the comments but there are a couple of post of owners with 100k plus who haven’t had any issues, the 2.7 has been solid there’s just tons of bias with it being a 4cyl
Great video 👍🏽👍🏽👍🏽
Back to the Future..GM's old straight six 292 cu. in. should be Re-introduced as a Turbo modern engine..I bet it would be a Beast
What concerns me is that you stated that it has a 9,000 lbs or so towing package. So when do you think that this package will get out of boost doing that, I think maybe going down hill, can't wait to see the uninformed be shocked that it doesn't get 17 MPG. Seems far too complex for what it is, a lot of potential for engine issues and yes, put me down for a large displacement engine turning low rpm's to last a lot longer, just my two cents.
It’s not built for fuel economy it’s built to meet emissions, same story with the Hurricane I6 phasing out the Hemi. There’s a lot of tech in that engine to squeeze all that output, it might hurt longterm longevity.
but the fuel economy is not even good, that's the worst part.
@@TheGettyAdventures exactly, of course people not in the know will fall for the marketing ploy.
It is all about economy and power. Nobody could compete with the Ecoboost motors. The manufactures made fun of Ford for doing that, and going to aluminum, everyone is starting to follow that route, including Toyota. The N/A v8 motors can’t compete powerwise, and the torque curves, economy.
@@vr4787 Marketing ploy? It is better for consumers honestly. I drive a Ford 2.7 and still think that is the best motor, for anyone not towing over about 6k. I am a big EB guy, but that is because I Believe Ford is putting out the best, and most reliable turbo charged motors in trucks.
@@calebniederhofer6529I really don’t see how having to pay for high octane fuel for peak performance on a direct injection engine that’s prone to carbon build up, with GM’s issue laden AFM/DFM sytem that gets marginally better mpg than a 5.7 hemi like the video pointed out (which is less complex and more affordable to mod/repair) is better for consumers. If you think Ford ecoboosts are reliable they have their share issues especially with cam phasers waring out and turbos leaking as they age. It’s not a simple or cheap repair either. Squeezing all that power out of a smaller displacement gas engine comes at a cost.
I have a 2009 Silverado 5.3 with 243000 miles on it. I've replaced one ignition coil and that's it. I pull two different boats with it pretty often, and it feels like it hasn't lost any power. It's really been a good one! And it's showing 17.4 overall miles per gallon.
those earlier 5.3's were solid engines!
No one wants to drive that old POS
2007 4.8l 1500 classic 213,000 on it and ill do everything I can to never get rid of it.
04 super duty 241000
Almost 246000 now
The 3.0 diesel is the only way to go in these trucks and IMO is by far the best value. Inherently balanced, gobs of low end torque, and mine gets 23+mpg city and 30mpg hwy. It also will tow 13k.
It’s overhead cam, it doesn’t have lifters to fail
AFM on a 4 cylinder, this cant go wrong, not like they have a history of it.
It's all about the the final fuel economy number in the brochure.
If I remember I do know there is a company that sells a mod to delete the AFM.
I agree with you they seem shorter , not as high is it or is it just the way the body sits on the suspension?, I like it.
My 2020 had major lifter issues requiring a rebuild.75,000 miles along with 1500 idle hours. Not made for commercial work.
Nice looking truck.concerned about the small turbo.Dont think they last like an 8 cylinder, and that's important when you pay that much.
Alex - get a new 22+ Tundra and review it - please! The new 3.5 TT engine…I feel won’t live up to the legendary benchmark of the 4.7 and 5.7 v8’s! I’ve got 300k on my old 2008 Tundra 5.7 and nothing ever goes wrong with that damn thing, nothing! It’s like a cockroach…can’t kill it lol. Best vehicle I’ve ever owned - period. (…and I’ve had gm/ford/dodge gas jobs too). Also have two newer diesels…an LML dmax and a 1st gen 6.7 PS. The Ford 6.7 is a maintenance nightmare…the kind that makes you piss the bed. Lol
Shop has an 08, 10 and 13...all over 250k and NOT ONE issue with engine...that is remarkable considering they tow pallets of brick and skids
Don't forget the Tundra 4.6L V8 that replaced the 4.7L. It's even better than the 4.7 in my opinion. My 2013 has the 4.6L and it is simply a great engine. Hauls around our small to medium trailers (fishing boat and enclosed trailers) easily as well as our slide-in pop-up pickup camper. Runs about one gear lower than 5.7liter would pulling the same loads so I get the same mpg as a 5.7L when towing, but when running empty, I get 18 - 20mpg on the highway (hand calculated on 300+ mile trips) depending on if I drive 80mph or 70mph (80mph speed limits here).
Greeting Alex, This was a great video. Curious though I though this 2.7 was a Twin overhead Cam engine without the need of Lifters, and push rods as the Cam rolls the Rockers in this case. Thanks for sharing....
Pretty sure you are correct. It’s like he is confusing the 5.3 and 2.7. Maybe we are both wrong, by it I have never heard of a lifter failure in this engine and makes me suspect of the whole video.
I said lifters, the proper terminology is cam followers. but they essentially do the exact same thing. instead of a lifter listing a pushrod. The follower directly lifts the rocker arm.
So please explain your comment on Lifter failure. These won't have a typical spring and plunger lifter
Hey!
Great video.
Can you review the Ford 3.5 Powerboost hybrid next?
Yes, please!
For you know it they’ll be putting Briggs & Stratton V Twins in these things ! 😂
Once enough of these engines have run the gauntlet, we will be able to identify if this engine is really special or not. TFL did do a video with the head engineer when discussing the Colorado/Canyon powertrain (similar to this) and from an internal perspective it’s suppose to rely more on heavier components found in Diesel Engines. I highly recommend you check it out for a more mechanical breakdown
It might aid to the longevity, but the the fact it’s turbo charged leaves questions in the air.
Problem is a turbo will go eventually, maybe if you are lucky 200k 250k. But it's not that bad to replace a turbo
Good luck with that timing chain system. GM has a long, negative history with that little bicycle chain and plastic guides in its cars, and TFL didn't want to go there--like all the other interviewers that they have granted engineer time to.
Excellent Video, hella great info not found and been trying to do my Homework on this, much appreciated! Almost makes me regret paying over $40k for '23 Subaru Ascent w/2.4L Turbo Direct Injected Boxer Engine (but love that Subie!). Believe main GM reasoning behind this Turbo 4 cylinder is Cost. This is the Base Engine and my area GMC & Chevy Dealerships are Discounting these Sierra 1500 & Canyon Elevations as well as Silverado 1500 RST & Colorado over $10k! Why I'm so interested but after watching this Video looking at Nissan Titan & Frontier. Got a Video for those hopefully?!?
Interesting, I easily get mid 20s MPG with 87 octane, zero problem with my work/fleet truck. I've even done 26 on a good day of mostly highway.
