@@GettysGarage can you imagine the power numbers if it scaled like this engine as far as power per cylinder when I did the math it was like 640 tq and 460hp. Don’t know that it would scale like that but it would be a great motor
@mitchharris97 It does scale like that. Given the displacement it would be a 4.1 liter I-6 and would easily best the 3.0 Ram Hurricane just based on displacement. It would need to change the turbo though as I dont think the dual volute turbo would work on a 6, they would prolly have to go twin turbo but i could be wrong.
Respect to the Nano 2.7. Also Respect to GM for making this the base engine while Ford has the anemic 3.3 n/a. Ford targeted the 5.3 with the 2.7 and the 6.2 with the 3.5 and IMHO Ford came out on top. GM doing their wierd old GM type thing dumped all the development money into their base engine which ironically completes well against Fords mainstream offerings.
I bought the Turbo Max in a Colorado, despite being a little bit reluctant to buy turbo 4 vs a V6. I'm only a year in, but the power of this thing has won me over. It makes effortless torque, and is a blast in a mid size truck. It truly feels like a Diesel.
@@jamesgullo8240 I just want 150k out of it. I don't want to drive something for 20 years. If I can pay it off, drive it for another five and sell it for a few grand I'll be happy.

I have the 22 refresh silverado with the HO version. For a full size truck it does as well as the 350 did. I have friends who are over 150k on milage and tow heavy alot with theirs and no issues with trans or the engine. The way the oil pump is setup i been hearing carbon is not been a issue with these like people think on higher milage. The 8 speed does well to.
@@Oneshawdog89 towing is harder on the transmission than anything else. sure the engine has to try a bit harder, but the damage almost always ends up on the transmission, especially with any kind of hills
As an engineer, I i applaud GM for craming so much technology in such a small form factor while maintaining an extremely reliable product. I'm a diesel guy and previously owned the 3.0 Duramax and currently own the L5P Duramax... But if i were to ever leave the Duramax engine for a gasser, I would 100% consider this one.

As a truck owner ( hemi ram) and mechanic I’m rooting for this engine because I know most people don’t need 400 hp and 400 torque .. I absolutely 100% agree with you on the split port direct injection
@TheGettyAdventures Alex what's wrong with towing with engine? For the average person towing a travel trailer or snowmobile trailer this would be fine.
Traded my RAM in for a Sierra with this engine 3 weeks ago haven't had one regret other than couldn't get a crew cab long bed with the options I wanted. RAM priced me out of the market on trucks and the market value was dropping like a stone. I'm getting 23MPG on the highway on the 2 road trips I've taken and around 17.5 in the city I don't miss my HEMI at all. Tows my side by side better than my RAM did which shocked me.
@@chris6743 I traded my ram in for a Silverado with this engine haven’t looked back tows great drives great getting 23.7-24 mpg highway and running around town see 19.5 mpg vs the 15-18 I was seeing with the hemi
That's why the Ford 2.7 ecoboost is such a great engine, 325 hp 400tq. It's a great engine for the majority that doesn't need to tow a 10K trailer frequently, yet can still do it now and then without worry. I have the 3.5 ecoboost, it tows anything that a half ton should be towing effortlessly with power and torque to spare.
That engine is super surprising. My brother in law has one. I have a 2021 3.0 Duramax and man his feels so much like the diesel its unreal. Super impressive.

I bought a 2024 Colorado 2wd with this engine package. My wife told me that she didn't want a 4 cylinder engine in a truck. I drove it on a test drive and couldn't believe how well it performed. My wife was very skeptical and she drove it and I told her to get on it and before she could even touch the Brake we were doing 75. She just quietly drove it back to the dealer and told the salesman it was sold. The LT package was really nice and for 34,000 dollars it is a bargain compared to Ford and Dodge. My best mileage has been 30 mpg on the highway and I couldn't be happier.
This is one of the coolest i4s ever, imo. I've always respected any team who has the guts to make off-set cylinders as it's simply a superior method but requires a lot of engineering to iron-out the follow-up issues.
I have a 24 and I just recorded 26.1 mph on 100 mile highway run at 70 mph . As far as the cylinder deactivation if I put it in tow haul it doesn't come on . When I'm just driving around town with the cruise control on at 45 or under is about the only time it comes on .
It's great for camping. Can leave it idling for days. It also actively shuts down cooling as needed, so it can idel very low with 2 cylinders without getting too cold.
I got the LM2. I love it. Couple issues long crank, intermittent nox2 efficiency, and just recent oil consumption. 1 quart per 1k miles. Keep an eye on your oil.
@@TimHancock-h6ethere’s a tsb for the intake cracking causing oil intrusion to the air charge and causing early regen which might be causing the nox issue and thus the long crank because it takes more compression to ignite oil vs diesel…
Bought my 24 in January and I absolutely love this truck. I have been really impressed with this 2.7 4 cylinder. Plenty of power, especially in sport mode, and I actually average about 23-25 MPG on the interstate. The turbo also has that diesel whistle sound to it. 5k miles with no issues. So glad I chose this engine, all the issues seem to be with the V8 engines.
I have seen quite a few of your reviews and the are well thought out. As GM was first rolling out the TurboMax engine i saw the engineering video and i was quite impressed with the structure and the rigorous testing. Now that GM has boosted the warranty to 100,000 miles and seeing this review, i am very impressed. I would love to have that engine in my 2002 Tacoma regular cab 4x4! It would probably break my truck to pieces but that would be a blast for a little while though! After all, my engine is also a 2.7!
I had the 2000 Tacoma with the V6. It was lacking power (5200 ft altitude), so the 2.7 must have been tough. The GM 2.7 is night and day difference. You can actually merge onto the highway with ease. It will pull a hill on my commute at 1800 rpm in top gear (75 mph), where the Toyota needed to downshift to maintain speed (5-speed manual). Definitely a torquey motor down low, but spins up to redline just fine. It does get a bit noisy as the rpm get above 3500.
@@davidmckibbin4440 That's pretty hard to predict. The frame on the Toyota was rusted out pretty bad when I sold it. Drivetrain was fine @ 198,000 miles. If the frame lasts another 10 years, I would be surprised. I suspect the Colorado will still be on the road in 10 years. Even if it is not, I would not go back to the 2000 generation Tacoma. It was a good truck, but it was loud inside, didn't have power and didn't drive very well. I am sure Tacoma's have come a long way since then though.
I had one and loved it. Didn’t like the old 8-speed transmission but I hear they updated it. Power delivery on the 2.7L is shockingly similar to my 3.0 Duramax.
I personally think all 4 of GM'S engine options are excellent and offer great diversity depending on what customers are looking for. I decided on the LZ0 when i got my 23 LTZ and i couldn't be happier with it so far!!👍
I bought my 2.7 turbo in February 2024 and am happy with it. I tow a small 21’ wolf pup trailer and it does really good. One thing I noticed however is if towing up a steep incline, it doesn’t like to be pushed. It’s more happy in the 2700-3200 rpm range. If I floor it, the engine just revs up and slowly accelerates, whereas if I accelerate gently and let it downshift it will accelerate better
Ya if you punch it all a sudden you will loose the power band. Ecu will kick back at ya a lil. Seems its just programmed that way? Ease on the 2800 or 3400 rpm it wont do that. Torque curve changes over 4400 rpm.
I'm still annoyed that they stopped production on the LWN 2.8 L Duramax. It was already the most fuel efficient truck by quite a bit and they could have paired it with the 10-speed automatic to make it even better.
I don’t know about the durability of these highly stressed small turbos but I recently drove a F-150 2.7L and it drove like a V8 and got 31mpg. I was impressed.
@@johnk6206 That’s strange. The one I was driving was empty and it was almost all highway. The turbo seldom kicked in, maybe that’s why I saw that mileage. I wouldn’t have believed it either if I hadn’t seen it.
I’ve got a 2023 chevy silverado 1500 with the 2.7. Almost 50k miles of pulling a 5klb trailer. Uses about 1.5 quarts of oil in 5k mile oil change interval. It doesn’t burn it, it loses the oil somewhere in the turbo system I think. These trucks in the WT trim are freakin sweet and super easy to work on. I like Fords for the luxury trims. But I think for smaller work trucks, the 2.7 GM engine is the best option.
Does it read low on the dipstick when it's 1.5q low out of 6? Mines got 13k is all, and doesn't really seem to burn more than like maybe a pint between the 3.5k intervals I've been doing.
Ive had the 2.7 turbo for about a year now and love it. Im not concerned about the direct injection carbon buildup at all. I think people make it a bigger deal that it is. My previous truck had the 4.3 v6 with direct injection. I saw the valves at 120k and they really weren't that bad. If anything youd need to get them walnut blasted once in the life of the truck. Not a big deal
@@davidmckibbin4440 Had them scoped when the spark plugs were changed. I was thinking I should have the valves cleaned too cause everyone says how bad the carbon build up is. It wasn't. I kept that truck for 9 years, over 130,000 miles. Bought it new in 15. I guess it's how you look at things. Everything can be a big deal to you or "whatever" life goes on.
After a year, I have *never* seen the ECO light on mine come on. I'm not a leadfoot either, I think it just activates under a very minimal set of circumstances.
It seems like they designed a 6\8 cylinder variant, then kept the cylinder deactivation tech when they reduced it to 4 cylinders. I can’t imagine the gas savings is even measurable at the pump.
This AFM is a copy of Honda's VTech. And Honda's VTech works just fine. GM just took it up a notch and added a 3rd profile for the cylinder deactivation. Keep the oil checked and changed and there won't ever be a problem
I have a 2024 LT with this motor and my last truck was a 2021 Trail Boss with the 5.3 v8. The 5.3 performed much better. The Turbo Max isn’t terrible, and is probably fine for guys who don’t really haul anything. I think it’s a little under powered and doesn’t haul or tow as well as advertised, it’s also a little sluggish on the expressway but moves well once it’s going. Gas Milage is actually much worse than the 5.3.
What are you towing? It’s designed for lighter loads than the v8, so it will feel underpowered and drink more gas if you tow at the top end of the v8 ratings. The 3.0 Duramax is the better engine for efficiently towing heavier loads.
The 2.7 smokes the 5.3, what are you guys smoking for real. I have had both, no competition. Look at the dyno sheets and torque curve. This will back up my claim. The 2.7 dosent work nearly as hard as the 5.3 also
I've owned a 2023 Silverado for a year now and am quite happy with the 2.7. On a few random occasions, it had like 5 seconds of slight vibration after startup, but no driveability issues so far. There is plenty of power, especially the torque down low is awesome. Wish it sounded like a V-8, but you can't have everything. It makes for a great work truck and is actually very quiet while cruising.
I’m looking at a new one right now. I own a V6 now love the truck but you can tell the lack of power. I’m hesitant but your video has reassured me Thank you
I drove the GMC version of this at my job in truck rental. I was thoroughly impressed with the amount of power the engine gave. It honestly felt like something that would hold up for a long time.
I’ve been doing some research before I purchase a new truck this year. I found your videos during this research and wanted to say I greatly appreciate the content and you earned my sub even tho I don’t buy new vehicles but every 10 years lol
I have been driving a 2023 Canyon with the turbo max since march of 23 and have had zero issues and love my Canyon Elevation 2wd that I ordered with about 4k in options. After my GM discount and ttl, drove off the Dealers lot for 41,500. Best truck ever.
I learned my lesson with GM when the DOD failed in my Sierra destroying the engine. I understand this doesn’t have those but what it does have looks even more fragile. No thanks
What do you get combined? I am getting 13.8-14.0 l/100k according to the trip computer. I do mostly highway driving with a bit of city driving every day. I always use cruise control when I can on the highway. I have a canopy, bed slide and a bunch of tools in the back so it has a descent load at all times.
Ive had my 2023 GMC Sierra turbomax for almost a year now, approaching 8k miles, maybe getting close to 22-23mpg, I don’t tow anythin, just have this for the family, and throwing kayaks and bikes in the bed… very happy with it so far.
Greetings Alex. The main problem with AFM and DFM is that when they fail the cost of engine repair is higher. So then the treasure of some companies and workshops is to disconnect these "Fuel Saving" systems in software and mechanically. What fun from GM development engineers. A pleasure to see your videos, analysis and comments; Thanks Alex. I send you a big hug! 🤠
Excellent review, thank you. Wish you compared to the other motor options offered in the silverado 1500. I am thinking about buying one and people are talking me out of it, saying the v8 or v6 is a better choice.
I don’t like the active fuel management on a 4 cylinder it is a waste and you are looking for problems look at the GM V8 with the afm it is a nightmare
2011 gm made fun of ford for the 3.5 ecoboost and it’s embarrassing how much better it tows than the 6.2 to this day still. Then bam gm drops a 4 banger in a full size 😂 the 2.7 to get is the ford.
Set the cruise at 50 mph and then reduce your speed 1 mph and wait 3 seconds and see if you do not hear a rumble strip sound? Mine did. And the dealer refused to fix it. So I traded it in on a Honda Ridgeline.
My buddy blew his 2.7 on his 2024 GMC at 6,000 miles. Warranty denied at the first dealership. But the second dealership did it and had to fight gm to get the warranty changed.
@@ews360 Technically yes, but one of the dealerships in our area tries to avoid any possible warranty work. So they will deny warranty claims for things like "Modifications" (Stickers on your rear window).
@@firedflesh5427 One of the largest reasons I buy new every 5 yrs is for the bumper to bumper & drivetrain warranties. I save receipts for correct viscosity dexos oil & a/c delco oil filters, & document all my oil changes date/mileage/% of oil life remaining in case of failure. Hasn't happened yet. Never modify anything. Dealer doesn't "eat it", manufacturer does.
Ive been hammering on my turbomax colorado for over a year now... 13k miles in with no issues other than its pretty loud and makes a lot of noise, but honestly it eats
i have a 23 Colorado. 2.7 turbo plus motor, one year later 19K later, fuel milage got better after 12K miles, great motor for a mid size truck, now getting 22 mpg in suburbandriving,25 mpg in highway driving, LOVE the power of the 2.7 haven't tested the 7700 pound tow rating yet
Similar boat. 23 Colorado with the HO tune. 25k miles so far with 10% of that towing around 6k lbs. I’ve got a rack and tent over the bed and I live in a hilly high elevation area but it still gets combined 18.5 mpg. It tows great, plenty of power. Honestly the rear suspension felt like the weak point at 6k lbs, more squat than I’d like. The engine didn’t even care and happily sat at 2300 rpm on the highway with that load in tow.
I have a 2022 GMC 3500. It has the 6.6 gas motor. It’s been flawless for 35,000 miles but being direct injection has me constantly fearing carbon buildup on the intake valves. I’ve been considering some kind of additive to put in the gas but don’t quite dare at this point. All I do is try not to let her lug down to low RPM when pulling hard. I dont know if this helps prevent that potential problem or not.
Have you actually looked at high mile Ecoboosts without port injection? The valve build up is not really an issue. The main reason Ford and Toyota(they actually did this in 2006 on their direct injected 4.6L V8's) went to dual injection is because direct injection has no benefit at low engine load/cylinder pressures. They use the port injection to reduce the demand on the high pressure fuel pump and the associated drag on the motor when DI is not beneficial. Since this motor has AFM, its cylinder pressure is almost always going to be high and DI will almost always be beneficial. If its load is low it drops to 2 cylinders and the load doubles in the active cylinders. This is probably the same reason GM has chosen not to go PI on the V8's either. They have had AFM or DFM for a long time, something that Ford and Toyota never had in their V8's. Ford only added cylinder deactivation to the 5.0 in 2021, 3 years after it got dual injection.
I had Silverado with 4.3 DI. Had a look at the valves at about 120k and it wasn't that bad. Could've been cleaned but wasn't enough to be causing any problems. Maybe at 200k it would of need to be walnut blasted which is not the end of the world. Auto media makes the carbon buildup in direct injection a bigger deal than it is in my opinion
I have a 2022 2.7l HO. The dealership had to install a rebreather system due to dust in the emissions. I do use it in harsh conditions but have been pretty disappointed with emission related engine codes.
Remember when Ford spent millions on marketing for the Ecoboom 3.5 in 2011? They made it look like it was bulletproof. Same deal here, just a different mess. GM has no issues with extending powertrain warranties. Hell, when they go bankrupt again taxpayers will bail them out.
I have this engine and the the knocking is quite horrendous when cold. I assume it needs seafoam (problem is ive jo clue how to apply it, there is no simple air intake throttle body like my other vehicles). It also has a horrible transmission jerking issue when autostart is enabled (i always disable it).
20,000 miles on my 23 often towing 7x16 box trailer through east coast hills / mountains. NO REGRETS... I will say MPG towing is horrible... really horrible.... but as a daily driver MPG is decent and the truck drives great.
If you're manufacturing a four cylinder engine specifically to be turbocharged, you need to beef up the internals to stand up to the extra stress for the longevity of the engine! Like everything, stress will shorten it's service life if it is not taken into consideration when designing it! Things like larger journals both rod and mains, bigger rods and forged pistons, forged crank, beefier block casting with webbing and gussets as well as improved cooling capacities!!! Essentially, you need to build it like a Diesel engine!!!
I bought a Sierra 2.7 a month ago and I have 1100 miles on it so far. As of now I have 0 complaints it has great power and the low end torque has me off the line and up to speed easily. I’m worried about the longevity of the engine long term but the 100k mile powertrain warranty does ease my mind a bit. I’m hoping in 3-4 years as I get further into ownership we will really know if it’s a reliable enough engine to hold on to for years or if I will dump it after warranty is up.
@@kennethobando5755 the 2.7 L is actually quicker 0 to 60 than the 3.5 L it also makes more torque at a lower RPM. Cast iron block versus aluminum, turbos integrated into exhaust manifolds and a few other things.
I bought a new one Saturday. Was wondering if anybody had 2 issues I've seen. 1. The right turn signal stopped self canceling for about an hour yesterday but started again and hasn't had any failures today. 2. A strong electronic burning smell with no smoke happened once Sunday and once today. Smell only lasts about 30 seconds and is completely gone within 45 seconds. Any thoughts are appreciated.
I have a 2021. Incredible truck all around. For the most part, the only people I've been really seeing with issues are the people using the 4 cylinder for heavy hauling. I love my Silverado.
I used to have a turbo charged scion TC, nothing crazy in terms of power, but to think that these days you can get a beast of a turbo 4 banger like this in a truck is hilarious. I wish i had this in my Scion LOL.
Always love your real world reviews. You are making me re-think my Duramax 3.0 in my 1500. Would love to hear your take between the 2 engines since the specs are so close.
The diesel gets like 50%+ better mileage. And puts out more torque. I think it is a great choice, I personally just cannot afford the extra 20K in the trucks you can get it in. :D
I’m thinking about trading my truck in for one of these. I came here to learn about it and I love the horse power. 9500 lb towing. I like it. Over 4 inch heads, dual overhead shaft.
Bought a new '22 2.7 silverado trail boss custom the begining of '23. Currently, I have about 39k mi and is my daily driver. At 23k mi my turbo went out and it was replaced via warranty. At 29k mi my purge valve malfunctioned. Then at 32k mi my collision detection sensor stopped working. We will see what the future stores of me. As much as I love the truck (and the sweet Sand Dune Metallic paint), I am very worried I'll have an expensive repair as soon as much warranty runs out. The worst part is I am sort of stuck with the truck at this point. I commute rather far for work and it's made me quite a bit upside down on trade value. The stigma behind this 4cyl (although the stats on it are incredible) makes it difficult for dealerships to resell. My dealership had like 8 of these 4cyl on the lot. 6 remained for a very long time. I don't know if they got sold or moved to another dealership. I worry this will make my trade in value rough as well. This isn't a "buyer beware" post, because I could just have a lemon. This is just sharing my experience. I truly enjoy the truck but replacing a defective/blown turbo is not a cheap fix when the warranty is gone.
How does AFM solve the issue with the engine block heating and cooling differently. Mechanics have told me it causes cylinder warping and oil leaking past the rings because parts of the engine block are at different temperatures.
I wish GM would add two cylinders to this engine. GM, PLEASE BRING BACK THE STRAIGHT 6 ENGINES. I have the 3.0L LZO duramax and just love how smooth it is. Pulls great as well. Would love to have a gas version.
i have a 2023 custom exactly like this one and im really amazed by the performance of the engine. My only real complaint with this engine is the fuel economy. It's not horrendous for a full sized truck but for a 4 cylinder its absurd. Still love my truck tho.
It’s interesting, a ton of owners say the same thing about the MPG. I did a fuel economy loop the day and honestly it killed it. But when I reviews the first 2.7 my fuel economy was terrible lol so idk.
Watching all your videos over time on this is telling. I am a diesel mechanic turned service manager turned facility manager. I think Chevrolet might have a hit with this one. I love my 2.7!
I mean like I mentioned its not a 350 small block. But for all the tech smashed into it, they are holding very well. something I did not see coming. I thought this was going to be an absolute grenade for GM. similar to the 3L EcoDiesel from RAM lol.

Respect to the Nano 2.7. Also Respect to GM for making this the base engine while Ford has the anemic 3.3 n/a. Ford targeted the 5.3 with the 2.7 and the 6.2 with the 3.5 and IMHO Ford came out on top. GM doing their wierd old GM type thing dumped all the development money into their base engine which ironically completes well against Fords mainstream offerings.
I bought the Turbo Max in a Colorado, despite being a little bit reluctant to buy turbo 4 vs a V6. I'm only a year in, but the power of this thing has won me over.
It makes effortless torque, and is a blast in a mid size truck. It truly feels like a Diesel.
I was thinking these engines in a light midsize truck probably feel lightning fast

I have the 22 refresh silverado with the HO version. For a full size truck it does as well as the 350 did. I have friends who are over 150k on milage and tow heavy alot with theirs and no issues with trans or the engine. The way the oil pump is setup i been hearing carbon is not been a issue with these like people think on higher milage. The 8 speed does well to.
I have had my 2.7 Turbomax for 2 years. No problems at all and I love the power curve in this engine. It pulls 10,000 lb. Trailer with no problem.
Watch the temps when towing, as 10k lbs is going to stress that engine over time.
@@Cloud30000 I tow short durations of a large dump trailer loaded with a small tractor. The torque of this little engine is impressive.

I'm a diesel guy and previously owned the 3.0 Duramax and currently own the L5P Duramax... But if i were to ever leave the Duramax engine for a gasser, I would 100% consider this one.
Props to the re-review. Much more fair then last years Alex!
I know at the dealer, we haven't seen too many major issues with these.

very interesting, of the 4 GM engines in the 1500's which would you say has the most issues ?
Probably sounds like VW's 2.0T, it has a CGI block and sounds just like a diesel
As a truck owner ( hemi ram) and mechanic I’m rooting for this engine because I know most people don’t need 400 hp and 400 torque .. I absolutely 100% agree with you on the split port direct injection
I think for the average person who does not tow, or tow often. Something like this is very reasonable.
@TheGettyAdventures Alex what's wrong with towing with engine? For the average person towing a travel trailer or snowmobile trailer this would be fine.
Traded my RAM in for a Sierra with this engine 3 weeks ago haven't had one regret other than couldn't get a crew cab long bed with the options I wanted. RAM priced me out of the market on trucks and the market value was dropping like a stone. I'm getting 23MPG on the highway on the 2 road trips I've taken and around 17.5 in the city I don't miss my HEMI at all. Tows my side by side better than my RAM did which shocked me.
@@chris6743 I traded my ram in for a Silverado with this engine haven’t looked back tows great drives great getting 23.7-24 mpg highway and running around town see 19.5 mpg vs the 15-18 I was seeing with the hemi
That's why the Ford 2.7 ecoboost is such a great engine, 325 hp 400tq. It's a great engine for the majority that doesn't need to tow a 10K trailer frequently, yet can still do it now and then without worry. I have the 3.5 ecoboost, it tows anything that a half ton should be towing effortlessly with power and torque to spare.
That engine is super surprising. My brother in law has one. I have a 2021 3.0 Duramax and man his feels so much like the diesel its unreal. Super impressive.

I bought a 2024 Colorado 2wd with this engine package. My wife told me that she didn't want a 4 cylinder engine in a truck. I drove it on a test drive and couldn't believe how well it performed. My wife was very skeptical and she drove it and I told her to get on it and before she could even touch the Brake we were doing 75. She just quietly drove it back to the dealer and told the salesman it was sold. The LT package was really nice and for 34,000 dollars it is a bargain compared to Ford and Dodge. My best mileage has been 30 mpg on the highway and I couldn't be happier.
This is one of the coolest i4s ever, imo. I've always respected any team who has the guts to make off-set cylinders as it's simply a superior method but requires a lot of engineering to iron-out the follow-up issues.
I had a little truck with a weirdly large four cylinder (2.9L) and I really enjoyed it's "industrial" sound. I bet this engine makes a similar sound.
With an exhaust it sounds like a turbo honda
Honestly the turbo whistle is the most notable sound in my opinion
Looking forward to seeing more of this light duty content, especially the Maverick content
I have a 24 and I just recorded 26.1 mph on 100 mile highway run at 70 mph . As far as the cylinder deactivation if I put it in tow haul it doesn't come on . When I'm just driving around town with the cruise control on at 45 or under is about the only time it comes on .
Why do we need AFM on a 4cyl? Just keep em all rockin😊
It's great for camping. Can leave it idling for days. It also actively shuts down cooling as needed, so it can idel very low with 2 cylinders without getting too cold.
Time will tell, but I'm a 3.0 Duramax Diesel owner and I absolutely love it!
I gotta get a 3L back on the channel. I love that engine.

Bought my 24 in January and I absolutely love this truck. I have been really impressed with this 2.7 4 cylinder. Plenty of power, especially in sport mode, and I actually average about 23-25 MPG on the interstate. The turbo also has that diesel whistle sound to it. 5k miles with no issues. So glad I chose this engine, all the issues seem to be with the V8 engines.
Which trim level did you take?
LT crew cab 4x4
I have seen quite a few of your reviews and the are well thought out. As GM was first rolling out the TurboMax engine i saw the engineering video and i was quite impressed with the structure and the rigorous testing. Now that GM has boosted the warranty to 100,000 miles and seeing this review, i am very impressed. I would love to have that engine in my 2002 Tacoma regular cab 4x4! It would probably break my truck to pieces but that would be a blast for a little while though! After all, my engine is also a 2.7!
I had the 2000 Tacoma with the V6. It was lacking power (5200 ft altitude), so the 2.7 must have been tough. The GM 2.7 is night and day difference. You can actually merge onto the highway with ease. It will pull a hill on my commute at 1800 rpm in top gear (75 mph), where the Toyota needed to downshift to maintain speed (5-speed manual). Definitely a torquey motor down low, but spins up to redline just fine. It does get a bit noisy as the rpm get above 3500.
@@mikesamson1930 the 2000 tacoma will still be on the road when the 2.7 is in the junk yard with the new tacoma and tundra/
@@davidmckibbin4440 That's pretty hard to predict.
The frame on the Toyota was rusted out pretty bad when I sold it. Drivetrain was fine @ 198,000 miles. If the frame lasts another 10 years, I would be surprised. I suspect the Colorado will still be on the road in 10 years. Even if it is not, I would not go back to the 2000 generation Tacoma. It was a good truck, but it was loud inside, didn't have power and didn't drive very well. I am sure Tacoma's have come a long way since then though.
I had one and loved it. Didn’t like the old 8-speed transmission but I hear they updated it. Power delivery on the 2.7L is shockingly similar to my 3.0 Duramax.
I agree. I mention that when I’m towing with it. A little odd they don’t just buckle it up with the flagship 10 speed. But maybe eventually.
@@GettysGarage I wonder if it’s cause they wanted the longer gears for the turbocharger?
I personally think all 4 of GM'S engine options are excellent and offer great diversity depending on what customers are looking for. I decided on the LZ0 when i got my 23 LTZ and i couldn't be happier with it so far!!👍
I bought my 2.7 turbo in February 2024 and am happy with it. I tow a small 21’ wolf pup trailer and it does really good. One thing I noticed however is if towing up a steep incline, it doesn’t like to be pushed. It’s more happy in the 2700-3200 rpm range. If I floor it, the engine just revs up and slowly accelerates, whereas if I accelerate gently and let it downshift it will accelerate better
Ya if you punch it all a sudden you will loose the power band. Ecu will kick back at ya a lil. Seems its just programmed that way? Ease on the 2800 or 3400 rpm it wont do that. Torque curve changes over 4400 rpm.
430 lb-ft torque @ 3,000 rpm's That's where you want to be.
I'm still annoyed that they stopped production on the LWN 2.8 L Duramax. It was already the most fuel efficient truck by quite a bit and they could have paired it with the 10-speed automatic to make it even better.
Love mine
How do you feel about the longevity being its only direct injection? Carbon issues? That’s my biggest concern.
I don’t know about the durability of these highly stressed small turbos but I recently drove a F-150 2.7L and it drove like a V8 and got 31mpg. I was impressed.
I rented one and it blew me away with the acceleration.
31?! I had a 22 f150 2.7, and it struggled to see 19 on the highway. Fair power, but bad milage.
@@johnk6206 That’s strange. The one I was driving was empty and it was almost all highway. The turbo seldom kicked in, maybe that’s why I saw that mileage. I wouldn’t have believed it either if I hadn’t seen it.
@@CharlesCurran-m9p Curious how you know the turbo is kicked in; it is dual volet turbo and you shouldn't even here it at low RPMs.
@@RFRUS I didn’t really, I was driving very conservatively.
I’ve got a 2023 chevy silverado 1500 with the 2.7. Almost 50k miles of pulling a 5klb trailer. Uses about 1.5 quarts of oil in 5k mile oil change interval. It doesn’t burn it, it loses the oil somewhere in the turbo system I think. These trucks in the WT trim are freakin sweet and super easy to work on. I like Fords for the luxury trims. But I think for smaller work trucks, the 2.7 GM engine is the best option.
Does it read low on the dipstick when it's 1.5q low out of 6? Mines got 13k is all, and doesn't really seem to burn more than like maybe a pint between the 3.5k intervals I've been doing.
Increase oil change intervals to 3k miles and always a premium full synthetic like Mobile1 with that turbo.
why am I getting the late 70's early 80's vibes small motors in oversized vehicles
Completely different engine technology today.
Ive had the 2.7 turbo for about a year now and love it. Im not concerned about the direct injection carbon buildup at all. I think people make it a bigger deal that it is. My previous truck had the 4.3 v6 with direct injection. I saw the valves at 120k and they really weren't that bad. If anything youd need to get them walnut blasted once in the life of the truck. Not a big deal
Fair enough, I guess for me it’s just something completely preventable.
A few horror stories went a LONG way on the internet. Overall I don't think coking is near the problem it was made out to be.
sounds like you dont keep your trucks very long, why did you see the valves at 120000 miles, everything is a big deal on todays new cars.
@@davidmckibbin4440 Had them scoped when the spark plugs were changed. I was thinking I should have the valves cleaned too cause everyone says how bad the carbon build up is. It wasn't.

Afm is a deal breaker for me period! Also, I believe a 4 cylinder engine doesn't need it!
After a year, I have *never* seen the ECO light on mine come on. I'm not a leadfoot either, I think it just activates under a very minimal set of circumstances.
It is odd that a 4 cylinder engine would need to run on only 2 cylinders I agree.
It seems like they designed a 6\8 cylinder variant, then kept the cylinder deactivation tech when they reduced it to 4 cylinders. I can’t imagine the gas savings is even measurable at the pump.
This AFM is a copy of Honda's VTech. And Honda's VTech works just fine. GM just took it up a notch and added a 3rd profile for the cylinder deactivation. Keep the oil checked and changed and there won't ever be a problem
That may be true, but you are still going to have uneven loading, and thus, uneven wear between cylinders!
I have a 2024 LT with this motor and my last truck was a 2021 Trail Boss with the 5.3 v8. The 5.3 performed much better. The Turbo Max isn’t terrible, and is probably fine for guys who don’t really haul anything. I think it’s a little under powered and doesn’t haul or tow as well as advertised, it’s also a little sluggish on the expressway but moves well once it’s going. Gas Milage is actually much worse than the 5.3.
A lot of people mention the gas mileage not being great which I find interesting. And I agree with my trailer the engine just felt a little overhelmed
What are you towing? It’s designed for lighter loads than the v8, so it will feel underpowered and drink more gas if you tow at the top end of the v8 ratings. The 3.0 Duramax is the better engine for efficiently towing heavier loads.
The 2.7 smokes the 5.3, what are you guys smoking for real. I have had both, no competition. Look at the dyno sheets and torque curve. This will back up my claim. The 2.7 dosent work nearly as hard as the 5.3 also
Maybe it has more to do with the 8 speec then the actual motor i think this motor is great for the Colorado
I've owned a 2023 Silverado for a year now and am quite happy with the 2.7. On a few random occasions, it had like 5 seconds of slight vibration after startup, but no driveability issues so far. There is plenty of power, especially the torque down low is awesome. Wish it sounded like a V-8, but you can't have everything. It makes for a great work truck and is actually very quiet while cruising.
I almost forgot this engine was in the Cadillac CT4. A powerful motor meant for truck applications in a tiny sedan sounds like a blast lol
It's got a 8 speed tranny too the Caddy will haul butt.
I love mine. My lease was up on my 22 Silverado with the 5.3 and after driving one of these I was sold. Love the turbo
2:00 the turbo is the reason it making 90% torque @ 1500 rpm. Toyota Camry 2.5 has a slightly longer stroke and it peak @ 5,000 rpm.
Will this engine run well if you decide to want to turn off the active fuel management? Not a big fan of it.
I’m looking at a new one right now. I own a V6 now love the truck but you can tell the lack of power. I’m hesitant but your video has reassured me Thank you
I drove the GMC version of this at my job in truck rental. I was thoroughly impressed with the amount of power the engine gave. It honestly felt like something that would hold up for a long time.

Happy owner of a Silverado 1500 with 2.7T. The truck easily gets 10L/100km in highway driving. Has a nice smooth turbo whistling noise while driving.
What do you get combined? I am getting 13.8-14.0 l/100k according to the trip computer. I do mostly highway driving with a bit of city driving every day. I always use cruise control when I can on the highway. I have a canopy, bed slide and a bunch of tools in the back so it has a descent load at all times.
Ive had my 2023 GMC Sierra turbomax for almost a year now, approaching 8k miles, maybe getting close to 22-23mpg, I don’t tow anythin, just have this for the family, and throwing kayaks and bikes in the bed… very happy with it so far.
Greetings Alex.
The main problem with AFM and DFM is that when they fail the cost of engine repair is higher. So then the treasure of some companies and workshops is to disconnect these "Fuel Saving" systems in software and mechanically. What fun from GM development engineers. A pleasure to see your videos, analysis and comments; Thanks Alex. I send you a big hug! 🤠
Excellent review, thank you.
Wish you compared to the other motor options offered in the silverado 1500. I am thinking about buying one and people are talking me out of it, saying the v8 or v6 is a better choice.
I don’t like the active fuel management on a 4 cylinder it is a waste and you are looking for problems look at the GM
V8 with the afm it is a nightmare

Turdbo 2.7 sounds worse than a 1992 Honda Civic !
Similar boat. 23 Colorado with the HO tune. 25k miles so far with 10% of that towing around 6k lbs. I’ve got a rack and tent over the bed and I live in a hilly high elevation area but it still gets combined 18.5 mpg. It tows great, plenty of power. Honestly the rear suspension felt like the weak point at 6k lbs, more squat than I’d like. The engine didn’t even care and happily sat at 2300 rpm on the highway with that load in tow.
I have a 2022 GMC 3500. It has the 6.6 gas motor. It’s been flawless for 35,000 miles but being direct injection has me constantly fearing carbon buildup on the intake valves. I’ve been considering some kind of additive to put in the gas but don’t quite dare at this point. All I do is try not to let her lug down to low RPM when pulling hard. I dont know if this helps prevent that potential problem or not.
Get a oil catch can.
I did it'll keep from getting carbon buildup.
Fuel additives never reach the intake on a DI engine so save your money and buy a catch can and clean the intake every 30000 miles
Have you actually looked at high mile Ecoboosts without port injection? The valve build up is not really an issue.
The main reason Ford and Toyota(they actually did this in 2006 on their direct injected 4.6L V8's) went to dual injection is because direct injection has no benefit at low engine load/cylinder pressures. They use the port injection to reduce the demand on the high pressure fuel pump and the associated drag on the motor when DI is not beneficial.
Since this motor has AFM, its cylinder pressure is almost always going to be high and DI will almost always be beneficial. If its load is low it drops to 2 cylinders and the load doubles in the active cylinders.
This is probably the same reason GM has chosen not to go PI on the V8's either. They have had AFM or DFM for a long time, something that Ford and Toyota never had in their V8's. Ford only added cylinder deactivation to the 5.0 in 2021, 3 years after it got dual injection.
Hasn’t GM been using direct injection in their V8s for a while now?
@@ALMX5DPyes sadly
@ALMX5DP I meant PI. They have not gone PI because on DFM
I had Silverado with 4.3 DI. Had a look at the valves at about 120k and it wasn't that bad. Could've been cleaned but wasn't enough to be causing any problems. Maybe at 200k it would of need to be walnut blasted which is not the end of the world. Auto media makes the carbon buildup in direct injection a bigger deal than it is in my opinion
@danielbonner8309 I 100% agree and I scoped the valves on my first generation 3.5 L ecoboost around the same miles and they were almost spotless
I have a 2022 2.7l HO. The dealership had to install a rebreather system due to dust in the emissions.
I do use it in harsh conditions but have been pretty disappointed with emission related engine codes.
Remember when Ford spent millions on marketing for the Ecoboom 3.5 in 2011? They made it look like it was bulletproof. Same deal here, just a different mess. GM has no issues with extending powertrain warranties. Hell, when they go bankrupt again taxpayers will bail them out.
lol this is very true. no fear when the tax payers have your back.
Just because they have a warranty doesn't mean anything ...fixing a problem is when you see if they're serious .
You do know Ford took money from the government also? Right?
I have this engine and the the knocking is quite horrendous when cold. I assume it needs seafoam (problem is ive jo clue how to apply it, there is no simple air intake throttle body like my other vehicles).
It also has a horrible transmission jerking issue when autostart is enabled (i always disable it).
20,000 miles on my 23 often towing 7x16 box trailer through east coast hills / mountains. NO REGRETS... I will say MPG towing is horrible... really horrible.... but as a daily driver MPG is decent and the truck drives great.
So AFM??? It shuts off cylinders??
Too much shit to go wrong
If you're manufacturing a four cylinder engine specifically to be turbocharged, you need to beef up the internals to stand up to the extra stress for the longevity of the engine! Like everything, stress will shorten it's service life if it is not taken into consideration when designing it! Things like larger journals both rod and mains, bigger rods and forged pistons, forged crank, beefier block casting with webbing and gussets as well as improved cooling capacities!!! Essentially, you need to build it like a Diesel engine!!!
This video is about shit NOT going wrong with the 2.7 four cylinder.
@@garybulwinkle82 And that’s exactly what they did. I can’t recall where I read it, but they engineered it like a diesel. I really like this engine
I bought a Sierra 2.7 a month ago and I have 1100 miles on it so far. As of now I have 0 complaints it has great power and the low end torque has me off the line and up to speed easily. I’m worried about the longevity of the engine long term but the 100k mile powertrain warranty does ease my mind a bit. I’m hoping in 3-4 years as I get further into ownership we will really know if it’s a reliable enough engine to hold on to for years or if I will dump it after warranty is up.
Ford's 2.7 is lightyears better
How?? Is the ford 2.7 better and im a big 3.5 fan.
@kennethobando5755 The Ford 2.7 is the best engine Ford makes period. It's so overbuilt gets insane gas mileage.
2.7 is in a league of its own.
@thejosh0100 yeah 15 more horsepower and 30 LESS torque
@@Anonihmus2567 it’s less torque and only 15 more hp
@@kennethobando5755 the 2.7 L is actually quicker 0 to 60 than the 3.5 L it also makes more torque at a lower RPM. Cast iron block versus aluminum, turbos integrated into exhaust manifolds and a few other things.
24’ Zr2 Colorado. Love it. Things a rocket for mid size pickup.
5yrs/100k?
Yup, a month/500mi after that is about when I'd expect it to need a $11,050 engine.
I bought a new one Saturday. Was wondering if anybody had 2 issues I've seen.
1. The right turn signal stopped self canceling for about an hour yesterday but started again and hasn't had any failures today.
2. A strong electronic burning smell with no smoke happened once Sunday and once today. Smell only lasts about 30 seconds and is completely gone within 45 seconds.
Any thoughts are appreciated.
Fords 2.7 is way stronger and much smoother.
How do you figure a V6 with 4 main bearings is stronger than an I4 with 5 main bearings?
@@Holden-McGroin cgi block, webbed aluminum reinforced structure, cracked bearing caps, more bearing bolts.
I would agree with that.
For the cylinder deactivation, if the valves stay closed, doesn't that create a compression/suction scenario. where does the air in the cylinder go?
4 cylinders don’t belong in full size trucks!!😢
I have a 2021. Incredible truck all around. For the most part, the only people I've been really seeing with issues are the people using the 4 cylinder for heavy hauling. I love my Silverado.
Friends dont let Friends buy GM products
More zr1s for the rest of us
lol
I used to have a turbo charged scion TC, nothing crazy in terms of power, but to think that these days you can get a beast of a turbo 4 banger like this in a truck is hilarious. I wish i had this in my Scion LOL.
I have one in my 23 Sierra work truck. It sounds terrible, but it’s not down on power for what we use it for.
Always love your real world reviews. You are making me re-think my Duramax 3.0 in my 1500. Would love to hear your take between the 2 engines since the specs are so close.
The LZ0 is the best engine option in the GM half-tons. Especially with the max tow 3.73 axle ratio.
The diesel gets like 50%+ better mileage. And puts out more torque. I think it is a great choice, I personally just cannot afford the extra 20K in the trucks you can get it in. :D
What is the best mitigation strategy for the carbon buildup in this and the 2.5 LKO version of this engine?
It’s innovative, powerful, and reliable. Got to admire an engine that can be all that.
I’m thinking about trading my truck in for one of these. I came here to learn about it and I love the horse power. 9500 lb towing. I like it. Over 4 inch heads, dual overhead shaft.
I’ve had too much bad luck with my 4.3L AFM Silverado to get another engine with AFM. I’d get a duramax or 2500
Bought a new '22 2.7 silverado trail boss custom the begining of '23. Currently, I have about 39k mi and is my daily driver. At 23k mi my turbo went out and it was replaced via warranty. At 29k mi my purge valve malfunctioned. Then at 32k mi my collision detection sensor stopped working. We will see what the future stores of me. As much as I love the truck (and the sweet Sand Dune Metallic paint), I am very worried I'll have an expensive repair as soon as much warranty runs out. The worst part is I am sort of stuck with the truck at this point. I commute rather far for work and it's made me quite a bit upside down on trade value. The stigma behind this 4cyl (although the stats on it are incredible) makes it difficult for dealerships to resell. My dealership had like 8 of these 4cyl on the lot. 6 remained for a very long time. I don't know if they got sold or moved to another dealership. I worry this will make my trade in value rough as well. This isn't a "buyer beware" post, because I could just have a lemon. This is just sharing my experience. I truly enjoy the truck but replacing a defective/blown turbo is not a cheap fix when the warranty is gone.
It will be interesting to see the fuel economy test as the EPA numbers are pretty bad for such a small engine.
How does AFM solve the issue with the engine block heating and cooling differently. Mechanics have told me it causes cylinder warping and oil leaking past the rings because parts of the engine block are at different temperatures.
I wish GM would add two cylinders to this engine. GM, PLEASE BRING BACK THE STRAIGHT 6 ENGINES. I have the 3.0L LZO duramax and just love how smooth it is. Pulls great as well. Would love to have a gas version.
i have a 2023 custom exactly like this one and im really amazed by the performance of the engine. My only real complaint with this engine is the fuel economy. It's not horrendous for a full sized truck but for a 4 cylinder its absurd. Still love my truck tho.
It’s interesting, a ton of owners say the same thing about the MPG. I did a fuel economy loop the day and honestly it killed it. But when I reviews the first 2.7 my fuel economy was terrible lol so idk.
@@GettysGarage Alex it was terrible because it was winter and winter blend fuels are known for poor economy!
What mpg are you getting?
Watching all your videos over time on this is telling. I am a diesel mechanic turned service manager turned facility manager. I think Chevrolet might have a hit with this one. I love my 2.7!
I mean like I mentioned its not a 350 small block. But for all the tech smashed into it, they are holding very well. something I did not see coming. I thought this was going to be an absolute grenade for GM. similar to the 3L EcoDiesel from RAM lol.
I bought a 21 chev 1500 work truck, at 129,ooo miles the trans is toast and i have had problems with the starter motor needing replaced too.I have loved this truck since I bought it and have babied this truck since I bought it for my personal transportation when I retired in 21. I have only had the truck for 5 days in the last 37 as the rest of the time it has been in the dealerhip. Do the 21's have the same motor as the 4cly in this video. Mine is the 2.7 turbo but a different version My truck is the aluminum body1500.
