I have the babymax the 3.0 in a 1500 silverado. I love it. It pulls everything I need with ease and it gets 23 mpg combined even with all the towing I do (car and trailer 5k lbs @ 80 MPH)
Ive heard great things about the 4cyl tiny baby max.
OP
Isn’t the 3.0 a diesel?

My neighbors son got one in a suburban a year or two ago and he and his wife love it. He has claimed 29mpg on road trips.
I trust their opinion on diesels. His father ( mid 60's age) and he (43ish) have been road tractor owner/operators their whole life. Both run late 90's Peterbilt cabovers with Cats. The Dad ran an old 94ish Dodge 3500 with the 12 valve Cummins as a DD over 500k miles until it was stolen and replaced it with a mid 2000's 24v.
Son bought a 6.0 powerstroke new. Now nearing 400k without an issue (full bulletproofing years ago).
They also did small time grading jobs with those trucks, hauling equipment/dirt/whatever.
They both love/are impressed by the diesel in the new 'burb.

The motor I’m talking about is 2.7 tutbo charged gas engine. I’m guessing he has the 3.0 diesel?

My bad, saw the post after your op, plus "mind melded" babymax with the turbomax that you were asking about and went with the mini diesels😬🤔
No personal experience or knowledge with the 4cyl turbo in 1/2 tons. But the things I've read, heard, etc (I look into so much useless to my life but interesting to me stuff it's getting silly) are that if it's main use is as a commuter but every once in a while you pull a trailer or load it up with stuff. You will love it and it will provide you with a long and happy service life.
But if you "use" the capabilities of a 1/2 ton often, towing a small camper every weekend, working out of it as a builder, towing a small landscape trailer for work, etc. You won't like it and durability will suffer.
Basically, if it's mostly pulling around the truck itself. Gtg, happy day. If it's going to be loaded all the time, it will be constantly stressed and not as happy as a bigger option.
Not sure if it will hold up long term if it’s anything like the Chevy Cruz turbo 4 then no. More moving parts and items to break. Impressive HP and torque numbers I will give it. All I’d suggest is change the oil often and run exactly what GM calls for as far as oil. Worked on diesel turbos my whole life and dirty oil and air are there Achilles heel.
OP
We just bought one at work, atandaed
Cab 8’bed. Really looking forward to seeing it llong term.
Both of yalls answers was excactly the kinda stuff I was wondering about, Thanka

I've been looking at the Chevy Colorado with the turbo 2.7 and have been reading what I can find.
Here is an article that seems to cover a number of things that could be issues with the 2.7.
The AFM system is the one thing I do not like, don't like the idea of having an engine running on half of its cylinders.

How reliable is the Chevy 2.7L Turbo L3B engine? Read about common problems with the engine including AFM, HPFP, injector failure, and more.

There is a tool mentioned in the article that disables it without the computer noting anything.
That is the way I would go.

Didn't these suffer from wiring harness problems? I know thats not an engine related reliability thing but I know two guys with trucks with this engine. One finally traded his in due to the constant problems with the wiring harness while the second guy still has his and hasn't had any of the harness related issues.
OP
Have no idea but ya give me something to search,
I can’t believe no one on here has one. I’m guessing they just have me on ignore😎
They did not sell very well when they came out. They had plenty of them at the dealerships and they sat on the lot for a while. Now most dealerships keep mostly v8s and maybe 3-5 of the 4 cylinders just in case someone wants one. The fuel mileage isn't much different from the 5.3. if you are a person that keeps a vehicle for a long time, it might not be the best option, due to the fact that the turbos will likely have.to be replaced at some point.
Good luck
Good luck
OP
Great review. It told me basically everything I needed to know.
Still haven’t seen anything involving real world towing. Haven’t a few 5.3 chevy trucks pretty sure I would go that way again.

I drove a 2024 Silverado 1500 with the 4 cyl. last week. It did OK just driving it to it's destination, Beaumont Independent School District. Not a power house but, accelerated and had enough power to merge into traffic. But this was all flat land driving. Not sure how it would do with a trailer and a couple of Herefords.
My bosses new company truck is the turbo four cylinder. I’m not a fan of it so far. Seems to lack any power and his mileage has been roughly the same as when he had the V8. He told me when he came to the office one day with his family in the truck his fuel mileage went down 4mpg with nothing else changing. His drive to work is straight down I40 from Greensboro to Garner daily.
OP
I keep reading how the gas mileage is atrocious. It has the worse MPG in the GM 1500 series trucks.
The company I work for bought 2 new
Trucks before Christmas
2024 1500 ext cab 4wd with 5.3. Averaging 17.5 mpg now.
2024 standard cab 2wd with 2.7 turbo
15.3 mpg.
OP
I
What mileage you getting. You pretty much got a corvette motor😁😁
Personally, I would avoid this engine. I agree with everything the man said in the video linked above.
My opinion based on my life experience: More complexity increases maintenance and repair costs while reducing reliability and longevity. So far, I see no advantage to using a more complex engine in a pickup truck to do what a V-8 can already do. Real-world anecdotes from posts above are tending to bear this out.

Well , it's not as good as the 5.3L. The 6.2L is definitely fun 😁. It pulls my enclosed trailer like it not even there 😎.
I've got a years worth of data. I'll check the average and post it tomorrow. My averages have towing in them which is about 12.5 MPG. If you stay below 65 and don't stop and go a lot it can get 21-22 MPG. Around town and winding country roads it's 14.3-15.4 MPG .

Here's the averages so far in my ownership of my 6.2L TB for MPG.
15.6 MPG June -Dec 2022( very little towing) 7,500 miles
13.98 MPG 2023 lots of towing enclosed trailer 11,633 miles
My towing makes the numbers look terrible. I also don't do a lot of highway miles, it's mostly winding country roads. Down east in the flat lands I've got 22 MPG easy.
My 2018 6.2L/8 spd got better MPG's ,but the 2022 6.2L/10 spd is quicker for sure. It pulls hard in and gear its in unlike the 8spd ,which had places it seemed to not downshift at the right time.
OP
Not to shabby. Months ago I was talking to a guy at a Hendrick dealership. He said pretty much any 6.2 is sold almost immediately. He says that most of pep looking trucks to haul are wanting the big gas motor over diesels now.
Before anyone jumps in about the big duramax diesels we have 3 at work. All 2018 and above. They all are problematic. I personal would not buy one.
If buying personally get an extended warranty for all the lifter and transmission issues the newer gm's have. Even more so if it has a turbo.
