I went from a 2018 CC Z71 5.3 6 speed to my current 2019 CC 2.7.  
I averaged 17MPG in the 2018

I currently average 20.5 MPG in the 2019 2.7

If you’re looking to save MPG and don’t have a need to tow, the 2.7 is a great.  My 2WD rides like a Cadillac, after the 8 speed jerks from 2nd to 3rd.

I have about 2700 miles on my 2.7 and it’s been back to the dealership once and likely will go back. At first I thought it was a transmission issue but it appears to be an engine issue. It skips and sputters intermittently. All they did the first time was reset the ECM. Frustrating.

Are you easy on it? I'm wondering if owning a turbo is like a woman you got to open her up every now and then and ride her hard, and she will treat you better in the long run.

So you own People...   You should really reconsider the words you use on a online forum.

I can get over 20 mpg on E-85 at 60 mph with a 4.3 V6. Truth is I can't treat is bad enough even in the middle of winter to push it down to the 'national average' 17 mpg even on Ethanol.

Hey guys, have had my 2.7 for 6k miles and it's been good... But is it normal for this engine to rev pretty "loud" on accelerating from a stop? Once cruising the turbo accelerates it with a quiet whistle, but going from 0-40 sounds like it's taxing the engine for a normal acceleration.

Yeah it's a 2.7L engine trying to get a full size pickup going.  I love my 2.7L but yeah it sounds a little taxed from a stop.  I don't think you have anything wrong.  With a CAI I've recorded 6.8 second 0-60 not too shabby.

Thanks for the feedback. Which CAI did you get?

I need to find one and test drive it.  Not that I would get it but curious as to how it performs.  Seems like it does really well.

I bought a 2021 GMC Sierra 2.7 turbo I’ve had it for 6 months and I already put 18k miles on it she runs brand new still. Sometimes i regret buying because she’s a four banger but i’m telling it pretty fast for a truck. I think i’ve hit 0-60 in 5 seconds before (usually around 6-7 secs) and that’s surprised me. I wish there were mods and stuff you could do to them to make them even faster

I love my 2.7L but you never hit 0-60 in 5 seconds.

This is very true.

      6 Speed vs 8 Speed

      And to top it off finally.......................these small GM LS engines are designed to SPIN!!!!!  Why choke them down to just off idle for cruising.  Why/how the "bean counters" have influenced the "engineering department" at GM is beyond me.   They took a solid platform of an engine and turned into a joke in OEM form!!!

      Atlas,   Then following your logic we can't believe any story that the MSM produces? I mean it's documented they heavily donate to Democrat candidates. Vote Democrat in high percentages. Many MSM talents are married to Democrat politicians, Gov. employees. That goes for on-air and off, personalities and reporters. So they would all be biased and nothing they produce is to be believed in your mind?   Again the article simply was about ways AI can be used for pricing products. Nothing discounted current situations as a factor.    Again keep looking through your left/right lenses. I don't live my life that way.   And as a heads up this thread will be cleaned up again as much of this is off topic and is receiving

      So you're saying toss the baby out with the bathwater? @txab posted article was her take on how AI can be used to manipulate pricing as it already does and has been rebuked by the judiciasry in housing. How AI can be and is used to maximize refinery or even Amazon operations all of which are true but because she is who she is; that makes what she says about what is true, false? Is that something akin to Pre-justice aka prejudice?    Look, I'm first in line to approach all information with caution just because we live in a world where people like to lie about someone or something with such a straight face and in such volume that it makes digging to the truth wearisome. Meaning I understand the skepticisms but if I were to toss out everything a person is for a view they hold then my pool of people to draw wisdom from would be non-existent and I'd be forced to reinvent the wheel daily. Not practical.    "Be innocent as a dove but as cautious as a serpent."    Test each word. Every good lie is part truth or no one would believe it. Find the truth in it and reject what isn't.    On this one, AI is being used to do what has been done by hand for hundreds of years already but at such speed, the point of a computer, that it is more easily monetized. This one wasn't that hard a lift.    I wrote a few formulas in a Lotus 123 program decades ago, a series of linked Macros actually, that allowed a daily inventory to be turned into a running P&L and production plan. Something that took three departments a week to assemble now took the time it takes to input the 'daily changes' in inventory. Later that was ungraded to the more powerful Excel program an and integrated with bar code scanning, inventory to supply was done once per shift. It had a huge impact on production scheduling, Seamless interruption flexibility, inventory error reduction, raw materials cost effective utilization and scrap reduction. Huge improvement in the bottom line. I spent months on that and AI could have done it in minutes. So yes, it not only can be used, they would be foolish to not try. The legality, ethics and morality are not the domain of AI. Humans need to keep a reign on it.
