Well I'm very excited to get my hands back on this very interesting 2.7L turbomax inline 4 cylinder engine because it seems like alot of owners and buyers are having real success with this power plant of an engine.
I wanted to discuss 5 main things with this engine back in the shop. firstly however I go over some of the awesome new technology stuffed into this engine.
the first point I wanted to discuss is the updated warranty. GM has updated the standard powertrain warranty to 5 years/ 100,000 miles which is massive and I really like to see this. gives me good faith that GM is seeing these engine not having any major issues and they still feel like they can make money from them while extending the warranty.
Next is the strength of the engine. this little engine is truly built to be in a pick up truck with fully forged internals, iron liners, off-set cylinder, billet steel camshafts and a very stiff and strong crankshaft. GM truly gave this engine some good strength.
number 3 is cracking engine blocks. this was a bit of a panic for the internet but as it turns out there were only 12 engines that have has this issue to date. only a small handful. GM replace the full engine, no questions asked.
4th is the cylinder deactivation or Active Fuel management. and I wanted to highlight that this Turbotax engine goes about shutting down cylinders completely different then the V8's like the 5.3L and 6.2L engine that are having lifter failures with their collapsable lifters.
this engine uses its special cam shafts to shut down cylinders so we should not see as much valve train issues as the larger V8 engines.
lastly is just how much work GM had to do to balance this mighty 4 cylinder engine. with all the special tech and massive large stroke this engine should be very unbalanced but its not. In fact his engine in my opinion is very well balanced at all speeds.
lastly I discuss my unhappiness with GM continuing to not go with a dual injection fuel system with port injection and direct injection to solve any carbon build up issues.

As a 2.7 ecoboost owner, I do admire the simplicity of 4 cylinders and 1 turbo if it gets the job done.
Agreed.
The single turbo does certainly make things a little simpler.
It doesn’t…
@@TheHighway-mf3sl how does it not please share able to tow 9500 lbs 2200 lbs payload and 24 mpg
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
@VortexArcade Don't get me wrong, I wish you well with your truck. But my neighbor has 370,000 on his 5.3 L Chevy pickup.
@@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!
@@jamesgullo8240 Which 5.3 is the question. Because that is pure luck on AFM/DFM engines. Pretty that crap yes they were solid engines
If they had build a straight six version of this engine, they would have build the greatest offroad engine ever.
The 3.0 duramax is really good
@@Tiovergudo I guess is with the straight six they would't have needed all that extra counterbalance since inline sixes are naturally balanced.
From what I read. There was supposed to be an inline 6 engine and an inline 4. Turns out they only built the 4 cylinder.
@@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.
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.
Both those engine do have a similar feel. But I do love that 3L duramax
Until it comes time to actually use it as a truck.
@@TheGettyAdventuresthe baby Duramax is another trash motor with designed obsolescence built in.
@@edhcb9359 You don't use 1/2 tons to do truck stuff....that's for 3/4 tons and 1 ton duelleys.
@@Rich-xq3uv You might not, but most people can and do.
My company has several in our service fleet with well over 200k on them already. Been great.
Do vehicles in your fleet regulary hit 200k or are these just that robust?
@moyacosta6223 these are robust. I've seen it for myself. Even full time towing 7400lbs behind it.
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.
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.
I know at the dealer, we haven't seen too many major issues with these.
They are normally noisy though
Build a gas engine to run like a diesel, and it’s gonna sound like a diesel.
It is a ticky engine. To me it sounds like an older Honda VTEC. Maybe it has to do with the overhead cams.
@@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.
Props to the re-review. Much more fair then last years Alex!
I love the "Certified Dirty Idle" California sticker on the tool box" XD
Haha thought a couple folks would appreciate that
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.
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.
Tip of the hat to GM for a stout torquey motor that has been reliable. I didn’t realize it’s been out for 7 years now.
Crazy how fast it’s been. Granted the 7th year will be with the 2025 models
Looking forward to seeing more of this light duty content, especially the Maverick content
Great video! People love to hate on this engine but it just keeps working!
2.7 is the underdog, and i kind of like it.
Underdog is a great name for 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'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 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
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!
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.
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
Mazda has active fuel management on their 2.5 liter non turbo engine in their cars
It is strange GM felt the need for AFM on a 4 cylinder engine. Personally I don’t really like it.
To tell you the truth, as i own canyon with High output L3B
Afm is rarely even active
Nice job of breaking it down for someone who is not mechanically inclined. The channel should be renamed to “The Getty Professor “.
Well done.
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.
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.
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.
@@TheGettyAdventures I wonder if it’s cause they wanted the longer gears for the turbocharger?
Answered all my questions. Going to go buy one
This engine has been out for 7 years all ready ?!
in 2025 model year truck - yes 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 LZ0 is the best engine option in the GM half-tons. Especially with the max tow 3.73 axle ratio.
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 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.
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
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!!👍
JUST BOUGHT A 1500. .. LAST WEEK END.. .... .. SO FAR SO GOOD.. I HOPE I CAN HAVE IT FOR A LONG TIME👍
It seems GMs 4 turbo is more reliable that Toyotas 6. Who'd have believed it?
Nah gm will brush things under the rug and won’t fix anything. Toyta will fix it and make it right
@@freedomisntfree_44so Toyota is going to recall all 2024 Tundras/Tacomas and get them all a new engine ?
@@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….
It’s innovative, powerful, and reliable. Got to admire an engine that can be all that.
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
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 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.
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 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.
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.
that looks like a good motor to fit into anything!
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.
Very interesting. Was the vibration the cylinder deactivation ??
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.
They're all scrap
@@melvingibson4525 So are the GM V8's 🤣
V8 or nothing. No way I'm buying any turbo garbage. Dealer near me always has a half dozen Ecoturds in the shop with bad cam phasers.
@@nodak81 and people have ran them for 100k miles with that rattle and keep going. Not like the lifter failure gm has had
@@Jay-me7gw Tundra v8
Cool little engine. Too bad mpgs aren’t higher. Great video!! 👍
Wow a lot of thought went into that engine.
for a 4 cylinder engine, they shoved soo much tech into it. Which I guess is why I thought it would be a disaster, but as time has gone by they are seemingly holding up pretty well.
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 am sold on this motor, I have been a die hard it ain't a truck if ain't a V8 my whole life. Personally I feel these have less issues than the AFM V8's, if the V8's didn't have AFM I would still opt for the V8. That 430 torque is what really sells me on these motors.
Its too bad because I really like GMs V8's but the lifter issues kill it for me.
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.
@@TheGettyAdventures Alex it was terrible because it was winter and winter blend fuels are known for poor economy!
What mpg are you getting?
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
Only engine left without that scary tech is the Nissan, so choices are limited
No I wouldn't consider buying one but I'm watching because I enjoy your reviews.
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
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.
This thing would be great with a 6 speed to replace the 37hp factory engine in my '74 Mini.
This engine has two air/oil separators. No need for a catch can at all.
It will be interesting to see the fuel economy test as the EPA numbers are pretty bad for such a small engine.
Per fuelly, the avg MPG on the TurboMax is 18-19. On the Duramax 3.0, it's 25-26. So if you're getting 40% better fuel economy with the diesel, I wouldn't even say it's a close contest in that arena.
The only replacement for displacement is boost. It's a bit scary this thing runs at 22 PSI - that's A LOT of internal stress.
Waiting for the first manufacturer to creep up to the 30 PSI mark in the power war race.
Imagine a version of this with those new electric engines mounted in the transmission giving this thing 80 more horse and 100 ft of torque this thing would become really fuel efficient and pretty powerful.
I would consider this as a replacement for my wifes 2.8 Colorado if it only had the 10 speed. I think we could live with the other short comings but the GM 8 speeds have proven to be sub par (to be nice) and is basically a deal breaker. Looking towards the 3.0 SST standard output rught now but will give it a year or two.
I agree, the 8 speed is an odd choice. Why not just put the flagship 10 speed behind the 2.7L. Maybe in the future they will address that
@@TheGettyAdventures I heard “ somewhere “ that GM re did the whole eight speed transmission
I have had 2 GM 8 speeds no problems but all later builds. 8 speed came out in 2014 and yeah it had problems
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.
Stumbled upon your channel and sub’d! Any chance you’ll do a similar review on the current Frontier?
I would love to. where I rent my trucks from does not carry any Nissan products unfortunately. I have asked Nissan to partner with me so we'll see where that goes lol
@@TheGettyAdventures ah, no worries. I leased a 23 Pro4X and loved it minus a little finickiness from the transmission. I’m considering a Colorado/Canyon in a year or so and am apprehensive about the drivetrain (or overall quality/reliability). Thanks for the video!
It has a built in catch can
Certainly helps.
Great engine.. for a Honda Civic
Will it be a over heated toaster oven?
The L3B needs to be put into Colorado if not already but I do miss the baby duramax in the Colorado though!
It actually is in the mid size GM trucks. a great decision in my opinion by GM
How many miles are these engines lasting?
Looking forward to an update 84 years from now to see how it compares to my pre-war Flathead Ford.
this engine will be dust in 84 years lol
Will this engine run well if you decide to want to turn off the active fuel management? Not a big fan of it.
How do you feel about the longevity being its only direct injection? Carbon issues? That’s my biggest concern.
I think it’s a great engine for the canyon and Colorado, but I wouldn’t get it in a full size truck
Wicked engine for those mid size trucks.
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.
Don't over heat them and your good ! Run it in 100 temperature and Ac head gasket goes .
As a technician. I would have shown the front cover, turbo oil lines, oil pan and valve cover accessibility . How hard is it work on? Knowing the eco boost f150s failure points, i would have at least compared. All you did was state facts that you can find on any forum. Are you even a mechanic. You got 2 videos getting your hands dirty, and you're doing oil changes.😂😂 smooth buddy 👌
Oh boy, Austin Heft you keep working on your bikes and backyard scrap projects. I’ll keep fixing and rebuilding 15L engines. I turn wrenches 5 days a week, I do these reviews for fun. If you disagree with the review, by all means share your opinion. In fact, I gather a ton of useful info from guys just like you, because I don’t work directly on these engines. But getting your hands dirty on camera doesn't make you a good mechanic.
Honestly, completely valid points about potential failure points but usually try and address that type of stuff in a separate video just talking about the issues. Shoot me an email if you want and we can chat more about it.
@TheGettyAdventures okay got ya. Never have I heard of a hd mechanic having cleaner hands than a school girl. Have fun sweeping the floors and reading forum pages to find your info. Dude, like, come on. You got all this knowledge supposedly, and you read directly off the forum pages for engine problems. And you do video on how to change oil. Nice.
@@Austinandjules 😘
@@Austinandjules hey checked out your channel maybe change your handle to the backyard butcher with those builds ❤
I would feel a lot better about this engine if they got rid of AFM and added port fuel injection as well.
I agree, I think the addition of port injection and getting rid of AFM would make this engine even better.
Interesting the V6 in the Colorado gets better fuel economy.
The turbo loves drinking that fuel lol
The GM full-size chasis is wax coated not painted, it rubs off on contact down to bare steel, Lets see how that holds up in the northeast. Lets see how a turbo 4 cylinder holds up to high milage and actual "truck" type abuse..
Regarding the chassis, that's a bit of a disingenuous statement. The "contact" or abrasion necessary to remove the wax finish from the frame is quite severe. It's not as though you can wipe it off by hand. 😂
2:05 that rivals fords og 4.15L inline 4
But will it hold the same level of reliability
If GM would offer multiple gear ratios I think it would help sales out too
I actually chat about this when I tow with this truck. Because I COMPLETELY agree.
There is a lot to go wrong, (10) years or 150,000 miles should be a good test, we'll see. While the technology is there, it's no guarantee of progress unless this is a sealed for 200K engine w/o issue. The lack of port Injection is concerning as the effort to add port injection would have been minimal at it's inception. What is the oil grade for this engine? It seems like the more intricate of engines puts a real strain on the lubrication capabilities.
Too much shit to go wrong
Nice motor. Will it still be nice after 10 years? Who knows? I'll keep my V8.
I hear ya
@@TheGettyAdventures didn’t you say it’s almost 7 years old soon- so unless something just happens- we should have a fair idea already- Correct
I’ll only be able to afford one of these (in cash) when they are high mileage. very curious to see their durability after 100-150k miles and 10+years. hopefully very robust!
I don’t really see why they need to have have the cylinders drop off on a 4 cylinder engine you would think it would get great gas mileage without that ?
I’m genuinely curious if anyone can answer or even mr. Handsome Alex, why wouldn’t gm do dual turbo like Ford/Ram/Toyota? Just for simplicity sake or for reliability? Probably more to it but feels weird knowing they have a single turbo
Same warranty as the 3.0L Duramax Diesel as well.
Yes, very true!
It isn't a complex motor--it's just big for a four-banger. It's a 4 cylinder 16 valve DOHC. Practically every car in the orient has one.
Now they need to put this L3B max version in an awd Cruze SS!!! Pretty please @gm #gm !!!
...........or bring back the Cobalt SS and make it AWD and on the cheap fun like the LNF/SS! #gm @gm........
In a Mid size truck the 2.7 is OK. But I wouldn't want it in a full size PU. Unless it's used for hauling grocery's from! Wal-Mart!
Most pick up trucks are used for that nowadays.
For the complexity and problems vs the benefits, cylinder deactivation is a bust.
I honestly agree. I would imagine its for emission regulations more then anything which is just not fun.
I like my simple 2000 sierra 5.3 .
Toyota has used both port and direct injection in a truck since the 2016 Tacoma came out.
Without markedly improved fuel economy, what does this engine bring to the market? Reduced weight and a cheaper engine to manufacture.
Sliding cam positions?
Hey! Honda! Somebody coppied your VTech YO!
I have a 2021 5.3L without the DFM (due to chip shortage) no issues so far but can someone confirm if it still has the DFM lifters?
What's not being said.
That kind of power from 2.7 liters displacement means a lot of boost. I haven't been impressed with the LT engine due to its lack of durability.
100K mile warranty... great, I have 153K on my 4.8 in my 2011 Silvy.
With the prices every one wants for these trucks, all the different points of failure that's engineered into them. I can't see trading in a truck I can work on for one that I can't maintain myself.
I'm sure that's a great truck, I'll rebuild mine.
Thanks for the info.
Where in NB are you ?
Why would the 4 cylinder need AFM?!
If i ever was going to buy a light duty then i would only get a coyote or LZ0
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
