Armchair Engineer Gas Mileage Challenge

So here is a hypothetical question for all of you amateur (and maybe professional) engineers out there. If Toyota would have put the 5.7 liter V-8 into the 2022 Tundra, with the reduced weight, front air dam, improved aerodynamics, and 10 speed tranny, what kind of gas mileage do you think they could have achieved??? 20 on the highway? 21? What say you?

 

I'm in for this one

 

Don’t forget the gearing change as well! 4.30 ain’t helping us at the pump!

 

This ^^^

 

I'm an engineer. Idk.

 

How long before someone shoe horns on a supercharged 5.7 into a '22?

Sell the TTV6 to fund the madness.

 

Shoulda, woulda, coulda.

 

I would say at the very least 15/21, which is what ram is rated at with their 5.7. They only have an 8 speed as well. I think with the etorque, it’s 18/22.

 

I'd be more interested in putting a modern engine and transmission into an older truck that isn't the size and shape of an office building to see what could be done there.

 

I am an engi and i think the city number would not change too much, maybe +1. Lower gearing would certainly help this the most out of all the other things that were mentioned. I think the hwy miles would increase noticeably. Seeing as how i can get 18 mpg keeping it under 70mph now, i would say it could hit 21 easy.

 

The Sequoia weighs more than the Tundra and gets the same mileage. They put an 8 speed on the Land cruiser and LX which has similar weight as the Sequoia and still same mileage as the Tundra and Sequoia. I do not think there is much you can do about the fuel economy of the Toyota 5.7.

 

I'd like to see a 5.7 V8 powered by the ONLY viable alternative fuel source on Earth.
Hydrogen!

Electric vehicles are stupid garbage science that can never replace all other fuels due to all the electrical grid, manufacturing, mining, rare resource, charging, storage, disposal, temperature, load hauling, longevity issues.

Let's go Hydrogen!

 

I like the idea of hydrogen, but currently, about 95% of hydrogen is produced using fossil fuels. Someone would need to drastically ramp up different methods of producing it to make it a truly alternative energy source.

 

The answer is Cold Fusion.

i could maybe see +3 mpg highway, +2 city the 5.7 if it was equipped with the 10 speed and Toyota’s D4S system, which would push it to 15 city/20 mpg highway based off the 2nd gen ratings. Not factoring in the 3rd gen redesign for aero/drag and what not.

 

I check in on this effort from time to time, sorry to say this is still nothing but a fairytale.
They are not even remotely close to this being viable for day-to-day energy use, still after decades of research.

Besides, one day one of these scientist fools is going to create a black hole or some other cosmic fukup and destroy the planet/solar system.
Some things we simply are not ready to mess with at all, but nobody listens, "it's science!"
No, it's life and death when playing with cosmic building blocks and radical advanced dangerous theories.

Hell, the invention and use of the supercolliders alone could at any moment go wrong and destroy all reality, but they keep banging away at it anyway.
Fools, the lot of them.

I think to many scientists (and their idiot wealthy backers) often forget life is not like the movies, or Iron Man Tony Stark genius inventor, real life breakthroughs are slow and sometimes extremely dangerous and almost always go wrong the first time.
Some things we just are not ready to be messing with, at all.

I love science but it needs to always temper its work with extreme caution on things like this.

 

Yes, currently the tiny amount of Hydrogen produced is mostly made from fossil fuels due to existing production systems being cheaper and easier to use then making production cleaner right now.
Hydrogen could easily be safely, cheaply, and quickly ramped up.

Problem is there is no real demand for it, and everyone is scared of it since that long ago balloon the Hindenburg, which had nothing to do with the Hydrogen come to find out.
Hydrogen is not as volatile as many people think.

This advocate site provides some good information.

Instead of all the nutbags pushing electric power garbage science for day-to-day needs, we need to be pushing 110% on Hydrogen energy, which can be used for electricity.

Until we all demand it and stop this ignorant nonviable electrification of everything nothing will change because there is no money in something nobody needs at the moment.

Instead of pushing mpg/emission laws the Fed should be requiring and subsidizing the production of clean Hydrogen, and requiring automakers to switch all engines to it over time, phased in.
Same with gas stations and other infrastructure, but nothing is really being done as usual except finger pointing by climate change nuts and lately the garbage electric vehicle push which is a joke altogether.

Sorry to derail the thread, I get heated sometimes lol
