Thanks for update! This makes the Diesel pretty peppy IMO

So...Ford and Dodge and Toyota and Nissan don't have this same Obama standard apply to them ?

Cause they offer more gearing. 

Now granted the Ford is only 1 with 10 speed but they offer 3.13. 3.31 3.55 3.73

All I'm saying is that it would be nice to have options besides 3.23 which 95% of GM trucks will get . 

Same argument I have with only giving us a 24 Gallon fuel tank , when most others offer a large and small . 

These are options people will pay for . 

Your lack of understanding the CAFE issue leaves me speechless.

 

Im surprised you were even smart enough to buy a GM product.

I don't understand why CAFE is bad, I work in the auto industry as an engineer and I think it is great - the way I look at it, it challenges our minds, forces us to think outside the box and come up with better solution. I mean the car has very little incentive to evolve (usually war and other things pushes machinery evolution) and he is right, if it was only applied to GM we can cry about it but it is not, this applies to all OEM.
This is like the 30yo  that still lives at his mom basement because the world is unfair. while he is completely capable of getting a job and move out.

I think these type of challenges what result in better product, you never know this might result in pushing a better source of propulsion (electric infra structure - cough cough)

Another thing, 2.7L and 3.0L are the result of the CAFE which in my opinion both are great choices for a lot of people, if you want better fuel economy and don't tow much you got the 2.7L it is an excellent choice for day to day driving the occasional trip to the hardware store, if you tow light load regularly you got the 3.0Durmax good mpg while towing and nice low end torque.

I honestly think the 5.3 is ancient and should die, and replaced with some mid ranger turbo charged engine something larger than 2.7L

Last thing, buying a GM does not make such a person smart or stupid. being smart and making a bad decision like buying a new truck are completely different things.

 

Cheers!

Very well put! Once he's done being speechless , he can explain the goods  All I'm saying is that all other manufactures give you options for gearing.  

 

I also agree the 2.7 and new oil burner are excellent welcome additions.  I tend to agree on the 5.3. 

GM Already has a Turbo 3.6 that made 420/430 a few years ago . Why not figure out a way to up the torque some more and you have an ECOBOOST equal . And we all know how successful ford has been selling the ECO engine.  

[Moend]

Probably a patenting thing is the reason, cranking 430hp from turbo charged engine with flat curves

I never said cafe is bad, that is open to interpretation.

 

My point was that cafe standards are why you cant order just any gear ratio like you used to be able to.

 

If other company's are doing it, whats the tradeoff?

 

Going to smaller motors has proven troublesome as there are always unintended consequences like the early raptors drowning themselves if you stomped it after light highway driving in the humid southern states. Dont even get me started on turbo life.

 

If smaller motors are the answer, why aren't all mfgs going that route? There must be a reason.

 

Getting back to the gearing, go ahead and change your gears if you want to, but you can bank on the fact that the trans will NEVER stop hunting for gears.

 

With the 5.3/6.2 and ten speed that came up with a great and capable setup regardless of what gears people might think they want.

Going on fords build and price for the 21 models it is refreshing to have options like ford gives it's buyers. The coyote v8 with 3.73 gears outback and a ten speed sounds like a match made in heaven to me.

Last time I looked you could get that in a 2 door. It’s been a couple years though. Not the 10 speed then.

The 10 speed is standard on all their models except their base 3.3 work truck motor ( which changes as of 2021 as ALL of their trucks get 10 speeds now regardless.) 

yeah the 5.0 with 3.73 10 speed in a regular cab hauls the mail . There are a few Youtube guys out there with big whipples making big power.

Funny that you mention that as i was youtubing the other night and seen this on there. His friends reaction is priceless, maybe the smile was because in his follow up video he actually crashed into the back part of a dunkin donuts parking lot haha...

Glad they are ok but LOL! Your not kidding about this friend. " Hold my beer " or maybe iced tee ? 

Just looking at that guys truck man does it move out . Gen 5 whipple 3.0 makes some crazy power

See I find it hard to believe the reason GM don't offer the higher gears because of CAFE only, ot might be a contributor. Its probably to save on manufacturing more or less. Because it is a ratio. So they have to make so many of the fuel efficient ones to the one that isn't. Therefore they could've made few with 4.10 and such.

 

Now I do agree turbo charged engine might be troublesome if you ran them boosted all the time. And you are correct, actually a friend of mine had one of the early F150s in Huston and ended trading it for a 5.0 because of all the issues. In comparison my buddy in ND had a 14 ecoboost that was amazing never had an issue with it.

Also, most poeple uses their trucks as a car mejorty the time, yours truly is gulty of doing as such.

That is why I like the 8/10 speeds and that is why I like the cylinder deactivation. And I like all the technologies, if you can get me from point A to point B for half the price without compromising the things I care about and then why not.

 

Anyways, to not derail this thread more tthanwhat we have, I will leave it at that.

 

Cheers! There is nothing that beer can't fix

It's about a little thing called LIBERTY!  The government seized power not given to them by the people to advance a nefarious agenda and we're all the worse because of it.  We drives great cars despite CAFE, not because of CAFE.  They would be even greater without Uncle Sam's involvement in seemingly every aspect of automobile design and operation.
