I can't picture a truck so big with an engine so small. nope cant do it. theres no replacement for displacement. my 1997 Burb gets 17-18 mpg. I wonder how this one will perform.

3.7MPG? Are you kidding me? 17.8 MPG is what my 5.7 V8 gets in my 97 Burb with 400 000 miles on an all original motor.

Small motors are not economically in big trucks with numbers like that.

cknls, are you talking 5.3? I wanna know what the 2.7 Turbos mileage is but it is good to see comparison numbers.

I did not watch the whole video but I do believe they based that number from the 9 minutes of driving they did. man based off of all the numbers a carburetor big block get better fuel mileage while towing heavy loads.

there is no replacement for displacement.

not towing anything and with a combined highway and city driving, Car and Driver could only achieve 16 MPG while the EPA advertised mileage is 20 MPG.

My burb gets better mileage than that! in all conditions, towing, highway and city driving it is routinely above 17 MPG. I can also haul 8 people at the same time.

My cousin was pissed when I told him that his brand new (at the time) 2018 Silverado with the 5.3 AFM engine, only got 1 MPG better than my old truck and he had to feather the peddle to get the number up to 18 MPG. normal driving my old truck was better!

so Based on real world experience, I dont buy ANY of this ****.

another buddy of mine bought a ram with a van engine in it. 3.6 L I think. I dont remember what year. he uses it as a work truck. he sold me his old 98 Sierra for next to nothing and he loved that truck. he said he made a big mistake. this tiny engine is costing him an arm and a leg to use it like the work truck he bought it for. he cant hardly pull a trailer and if he does mileage is through the roof.

Gm has vowed to end the internal combustion engine by 2035. I'm pretty certain that they have already dropped some of their replacement engines and transmissions. I remember reading something about that anyways. like they did not renew the contracts with whomever does the remanufacturing of them. Iv seen some brand new engines still available so I'm not sure what the deal is. for the most part I'm talking about the 350/383. theres lots of LS stuff still available but GM is slowly shutting down support for the ICE!

Man this year's 2022 trucks dont have AFM or DFM. I think they have the internal parts, just not the chips or the programming. the 2022 5.3/6.2 trucks are probably going to be sought after.

theres no replacement for displacement. When your towing you need the largest motor possible to get up to and maintain speed. if your just getting groceries the little motor should do just fine.
