@@TheGettyAdventures 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.
@@danielbonner8309 I have a 13 year old GM 2.0T DOHC I4 engine (LHU). It sounds like it ticking and rattling like crazy at idle, and it has for the last 150,000 miles. It makes almost no glitter and is powerful, great engine! It's just the nature of DI engines with aluminum blocks.
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.
@@freedomisntfree_44is that why Toyota dealers are refusing to trade in tundras right now and don’t want to fix them? Toyota knew about the issue for YEARS and did nothing. There’s also a lawsuit over the rav4s coolant bypass valve and Toyota refusing to fix it. They have a long way to go on the Tacomas with all the issues that’s been having. Colorados and rangers are looking mighty good right now
@@freedomisntfree_44I disagree.They put out a service bulletin for the cracked block and are fixing them. Toyota is a mess right now with their two trucks. As of now there is no fix for the debris chewing up bearings in the Tundras Turbo 6. They were forced to issue the recall cause it was a safety concern
@@steven5096 must be too young to remember the 5.7 dropping valve springs, secondary air pump problems, throttle sticking. All fixed by 2010. I have a 13 5.7 with a quarter million miles without a problem. Toyota fixes their shit 👍 also to young to remember the 3.0 v6 Toyota had….
@@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
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 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. First turbocharged vehicle I've owned, I always lean toward simple. I sat in the Frontier and Colorado back to back, everything about the Frontier feels like it's 10 years old -not just the engine!
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.
Well, I have a 2020 Silverado Custom with the 310/348 version of this engine. I haven’t had any issues. Tows my 21 foot boat just fine, rides nice, dives good down in East Tennessee hills. I will say one thing, great gas mileage, but she sucks gas towing. I can live with it, she’s making power.
@@dannyt1705You wouldn't think there wouldnt be a need to deactivate cylinders on a 4 banger lol ... That's going to fail like all of their previous attempts at cylinder deactivation.
@@iGame2A Right . And on top of that this 4 cyl engine pulls 8000 lbs while Ford 3.7 v6 gas engine thats in fleet work trucks pulls 9000 lbs = at half the price . No body wants these things , literally . Ive been a GM guy all my life and this engine is a joke .
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.
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.
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
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
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!!!
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.
My Question IS… WHERE are the Front Bumpers on C-10’s, C-15’s, F-150’s, Rams and Tundras????? What happens when you find yourself with a 10 mph frontal “ mishap”??? All that front end plastic HAS GOT to be Expensive to Replace. Are vehicle insurances Much HIGHER on these front Bumperless Trucks????? 😳😬😠😡. CB
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.
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.
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.
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 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
It nice GM pay you said wonderful things 2.7 turbo engine but true story many failures with from turbo, long haul pull a trailer more less garbage it more 😢😢😢. Both my friends are mechanics one do it 60 years, and other 40 years GM Dealership and they gm fans drive 1 GMC Sierra crew cab, 2 Chevrolet Silverado both engines are 5.3 engines best engine stick which like best. Good luck on garbage 2.7 turbo engine suck bring back 70's Chevrolet Vega 😅😅😅😅😅😅
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
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.
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!!👍
the 87 octane doesn't matter on this engine, even with a turbo, thats because of the injection. They wait until the absolute last moment to inject it, it's computer controlled, and the computers are much very advanced nowdays, direct injection, so the air fuel mix will not pre- detonate, when piston is near TDC, look it up. That's the whole point of octanes. So now that they eliminated that from the equation go get you one. They are great.
If it didn't have that stupid AFM BS on it I'd seriously consider one... but I will never buy a AFM equipped engine. At least with auto srart/stop, that can be permanently disabled
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).
Alot of 4cylinder turbo hate going on be it chey,ford toyota fact is ive been a chrysler tech for 38 years these engines are the future thats a fact,they are man made and they can break,service them they will last.
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…
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.
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! 🤠
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.
Great video, except the timeline is confusing for the engine. The new version was released in 2022 but then you comment that the engine is 7 years, then 9 years etc for an engine you claimed was released in 2019. AFM on a 4 cylinder is laughable from a concept standpoint. GM is losing to foreign manufacturers with their 10/100,000 mile warranties. I feel the 2.7 was a dog in the Canyon/Colorado. Even more so in a full sized pickup.
I don't believe I ever mentioned 9 years. But I get the confusion, in 2025 it will be the 7th year of the 2.7L turbo and the 4th year of the high output turbomax. 2019,2020,2021,2022,2023,2024,2025. Hopefully that makes more sense.
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’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.
Yet the 90s v8’s all had less power but were perfectly acceptable then and somehow now? And yes I’m including the big blocks of that era. “V8 or nothing” dur dur dur🤦🏻♂️😂
Ironically it’s a better engin and the revised 8spd transmission than the 8cyl engines and 10spd transmission offered. It’s a beast in the mid size 3rd Gen refresh of the Colorado and Canyon.
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.
I have one and absolutely hate the turbo-lag from a dead stop with it! I hope it makes up for this with reliability……. but it is a very overly complex / engineered motor so…..
JUST... CAN'T.... DO.... IT..... I can't see myself relying on a 4 cyl anything in a full sized truck. It's a combination of blasphemy and witchcraft. Yeah, these modern technology engines are amazing, but they're over-engineered, over-complicated and over-priced to a fault.
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.
i can see the cross eye stuff but youre doing a great job. its almost impossible to tell. I can only tell because i'm an autist with attention to detail.
IDK, I'm in the (must have a V8) catagory for full sized trucks, I'd be fine with the 4cyl in the mid sized. Just bought a 2500hd 6.6l knowing gas mileage would suck but it's a truck! I really think they need to perfect the Cylinder disable tech and stick with 8 cylinders and add the turbo.
Its all hype turbocharging and 4 cylinders dont do well in full size trucks its like anything else there good because their new soon as the warranty ends problems start and the first thing to fail is usually the head gasket regardless of how well its built
Do you own one or just think you’re an expert without even listening to anything in said video? 7 years, no real issues, built more diesel like with diesel like delivery. Nobody bitches about turbos boosting the shit out of those. How long do they need to be out with no issue before you stop talking out of your ass?🧐😏
I got a 2021 Chevy Silverado 2.7 Biggest regret of my life. Transmission started giving me issues at 30000 got it fixed under warranty and at 58000 it’s in the shop for the 2nd time same issues. GM refused to give me a new transmission so this is the 3rd time they rebuilt the transmission and still not fixed Been in the shop for 4 months now
I'm a bit leery, but time will tell. Good to see Chevy trying to keep up with Ford with the forged internals and offset rods. Would have liked to see a CGI block instead of sleeved aluminum. Too bad it's not dual port injection. I do not like the cylinder deactivation at all regardless if it's a cam set up or collapsing lifters. I can't help but think a truck being driven mildly will have excessive carbon buildup on cylinders 2 & 3 and fouled plugs after 50,000, and this just compounds the direct injection issue (No way to rinse it out with an Italian tune-up). I could be wrong. Maybe in the future there will be a 200,000 mile tear down that might analyze this. It has amazing output numbers for such a small displacement, but it also runs up to 22lbs of boost from the factory.
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.
Pos . Like if I ran chevrolet or any company I'd fire anyone who wanted to put that into a full size truck . Today chevrolet rips you off for the 327 ... 5.3 litre v8 and offers the crappy 2.7 at what a truck with a v8 should sell for . Too bad people keep buying instead of showing chevrolet why you don't bite the hand that feeds ya
Understand the direct injection only "issue". While I'm not a big fan of additives, I've used Techron to good effect in motorcycle engines and my old 2007 5.3L which may have never had a problem. I got a deal on a case from a vendor and have been pouring a bottle in every other tank. Maybe it's snake oil but I feel better, what are your thoughts.
Never would recommend any GM vehicle to anyone. Company is way too shady and never wants to claim warranty repair or issue recalls that need it. Every family member or friend that got a new Silverado 1500 truck in last 3 years has already had to take it back for major repairs. Most were under 1200 miles. Bad injectors, lifters, fried PCMs ect.. Our shop receives tons of new GM vehicles plagued with electrical issues and unhappy customers fighting dealerships for warranty repair on blown motors and transmissions on trucks with less than 10k miles. As a electrical technician i just hope they get rid of the stupid RVC system on their vehicles. Why the hell does a alternator need a extra computer to shut its self off to temporarily save 1mpg of gas.. Every single one of these trucks give us issues. Sadly all these car manufacturers are switching to selling people half a engine in their new full sized truck to save on emissions and build cost at the customers expense and while still jacking up the msrp. Now that all brands are killing the V8 option and going turbo for cheap power there wont be any real trucks anymore. Just over boosted family SUVs with a bed that'll last 5 years before its more costly to repair than its worth. Idk why they cant just make a simple work truck without all the overly complex bs thats not 40k-50k.. My 2019 ram was only 28k new and it was decently packaged, same truck now its 45k. Absolutely insane price inflations these last 5 years. This same style 4cyl Silverado at my local dealership goes for 50k for a lower end 4door 4x4 model and 47k for a 2wd...
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.
I predict burned exhaust valves. The more you work it, the shorter the life. Maybe the basis for the warranty term. Boost = high cylinder BMEP and output, and the turbo raises exhaust restriction...increases heat transfer to valves. Which are pushing the limits of the materials they are made of even in more lightly used applications...I find cylinder leakage is usually the result of either stuck (usually not worn out) rings, or poor exhaust valve sealing. Exhaust valves that seal poorly also transfer heat to the seat poorly, so at that point, failure is a matter of time. Take comfort in that forged crank when you hold it wide open for 12 minutes pulling a heavy trailer over monarch pass in CO...but crank breakage is very rare, really...the 1600 degree egt is murder on the valves that you are not thinking about. Engines built to work hard are usually relatively large, and not all that powerful for their size...train, semi, aircraft... A top fuel dragster has plenty of power for a locomotive (for two or three, actually)......for about 4 seconds. Making the 11000 cubic inch v16 diesel a better choice, to me. High hp per cubic inch is interesting and impressive, but almost never results in long life, unless max power is used infrequently. Like a sportbike- yes, it may be 180hp, but spends most of its life making the 20hp it takes to make it cruise at 75 mph, even if you whup on it. 180hp also gets you 180 mph, so kind of limits the amount of time you can actually use it. This truck, with a trailer, is heavy enough that some people will actually use max power for quite a while. Crispy valves!
I’m very wary of this engine. I have it in my 2024 canyon. Just 1 simple engine component failure could be a disaster. I already had mine in the shop twice in 6 months for the air intake flaps. Could have caused overheating issue. Chevy needs to develop a turbo v6 like the ford ecoboost only better. The 2.7 is barely adequate in my canyon I cant imagine how it powers a full size. The mpg is terrible. I think it equals a Silverado with a 8 cylinder. There’s no reason to buy a Colorado or canyon other than fitting in your garage better. That’s the only reason I have mine now because a sierra or Silverado is too long for my garage.
How much oil consumption does this engine lose. I’ve seen them lose 1 quart every 2000 miles which I think sucks. Transmissions started having issues also.fuel mileage 11.2 mpg .drove this work truck every day to Work and back to shop 140 miles a day. Seats set to low and are very uncomfortable
People complain about the 1.2 and the 1.3 in the Trax/Trailblazer but not about this 2.7, even though they make almost the exact same horsepower per liter. I don't get 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 have 47k on mine. Very impressive. I don't tow often but pulling about 5000lbs for me is no problem. Again, quite surprised at performance and economy.
I’ve never had major problems with an engine in my two silverados, but everything else fell apart from transmissions, a/c compressors, brake vacuum motor, fuel pumps, coil packs. Etc. transmissions especially were 💩
No way. Just no. There's a reason the longest lasting vehicles ever built have double digit cylinders. You have to spread the workload over numerous pistons or the stress becomes too high. Would you rather lift 100lbs with one hand, or 50lbs in each hand? Hook a quad up to your self propelled lawnmower and use the lawnmower to tow the quad around your neighborhood. You'll see exactly what happens to an engine that gets over-stressed. Ultimately it all comes down to rotations. An 8 cylinder engine will produce more torque and will spin half as fast as a 4 cylinder engine. We measure engine life in miles, but in reality they work in cycles or rotations.
I would have preferred an atlas based I6 of around a 3.5l variety done by narrowing the bore and offsetting the cylinder centerline, then adding their new dual lobe tech to that, would absolutely stomp any econo version ford, or ram would build, and toyota would probably end up using a stroked version of the 3l BMW I6 currently in the supra, trying to keep up.
I have a 2022 custom with that engine and I a;lso know somewith with a 2019 with over 135k miles without any issue but the problem I see in the future is possible with the transmision. Mine kind of pausing a bit every once on awhile and I have heard other say the tranny is the weakest link with all their pickup trucks.
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
Any AFM and auto start/stop is bsd. I woulda considered a new ford with the 5.0l, but not with afm. The auto start/stop nonsense can at least be eliminated......the afm is different. Im not a fan of the 2.7 just because 4 cyl turbos dont make sense when there are solid v8 options.....but if i did have one id see about tuning out the AFM or disabling it. Just asking for major problems down the road.
