Referring to the torque, I regularly break traction with a 5,500 lb camper at stop lights on accident. From a dead stop this engine produces amazing torque.

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

[@thunderbolt5354]

Turdbo 2.7 sounds worse than a 1992 Honda Civic !

[@BradyReading]

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.

[@metalgeniusjoe5602]

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.

[@TheGettyAdventures]

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.

[@aidanpayan6919]

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.

[@matthewm3912]

[@Tuishimi]

I read a lot of posts, not just here, about people who berate Chevrolet, or people in Ford forums who berate Ford, on their choices and issues they've had and longevity, etc. I guess I am just one of those insanely lucky people who has NEVER had a serious issue with any vehicle I ever owned (except my first, poor, abused Subaru 40 years ago where I never had the timing belt serviced). I've owned two F-150s, a Ram 2500, and two 1500s (well, K10 and Silverado 1500 now) with no issues whatsoever. My take? I don't think you can go wrong purchasing a Ford or Chevrolet light duty or heavy duty truck. I think the naysayers (negative news/gossip) travels WAY more than the positive stories, since people who just truck along don't play around in forums saying "wow, I had another trouble-free day with my truck!"

[@pkmachinegun]

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.

[@TheGettyAdventures]

Its too bad because I really like GMs V8's but the lifter issues kill it for me.

Cylinder deactivation is what turned my off about these engines. Instead I chose the 3.0L I6 baby Duramax for my 2023 Silverado 1500. Despite all of the diesel pollution controls and DEF I still like the turbo diesel. It gets great fuel mileage, is surprisingly smooth and quiet and 30 mpg highway is easily achieved. That gives me over 700 mile range on the highway.

Greetings Alex. The main problem with AFM and DFM is that when they fail the cost of engine repair is higher.
