Where's the Hybrid TECH?

So trying to find out details of how the charging system works, when it charges, when it doesn't, why it appears to not charge unless already compression braking (a waste of energy), other things like that, and nobody seems to know where that info is. At the same time, although I'm supposed to be notified of all the posts here (2022+) I miss important posts and get threads like "how pretty are my wheels" buried under irrelevant subject lines. WTF?

Hybrid is for power, not efficency....so just drive your truck would be my advice. The answers you're looking for can probably only be answered by a Toyota Engineer.

Get used to the "how pretty are my wheels" posts, thats the way this site works. Also be ready to see the same thread started many many many many times. But on a side note the admins have been redirecting those wheel/tire, audio/visual, how big a tire without a lift, etc. questions to one place for all generations to make those also nearly impossible to filter down to usable information for what generation truck you drive.

Every now and then you'll find what you're after though.... a blind squirrel does find a nut every now and then...you know this because its still alive.

 

Actually it's for both, and i would like to find out how to optimize it. I would think that knowledge, if not here, is located somewhere where somebody here knows.

 

Not to be argumentative, but it’s really not both on these trucks. The improved mpg from the non-hybrid is almost negligible and the hybrid is almost exclusively intended by Toyota to increase hp and torque while not killing the fuel economy. I mean, the difference in EPA fuel economy rating is only 18/23 vs 20/24.

Go to Toyota’s Web site and look at the Tundra page. It touts the i-FORCE MAX increases in hp and torque in 3 places, but you don’t even see a single mention of improved fuel economy.

 

its because toyota never touted the hybrid system as improving mpg from inception/day 1. it was only for towing.

 

It is not for both. It is for increased power while towing. Nothing more, nothing less.

Mike Sweers is on video stating as such.

If you believe otherwise, you were sold a lie.

 

So actually it's not for both.

 

sorry i didnt mean to quote your post but the one above you.

my bad.

 

I'm considering starting a new thread on Tow Mirrors.

signed, a very blind squirell.

 

You should totally do that (totally random and oddly specific you mention tow mirrors.... Wink wink). Nobody has ever asked........

Even Better yet.."Bro, Whats the max size tire I can fit with no lift?"

 

Yeah, thought you might be able to relate to that one.

 

I'm 2-curious also on what it does. Also, what the life span? Will we be needing a new one in 6 years.

How do you get a Hybrid to do a pre-warm up when the engine shuts down to run off thr Hybrid battery?

 

I'm not expecting Prius level economy from a brick, but it would be nice to know when and how fast it charges. There is some improvement in fuel economy, obviously more city vs. highway. It seems some mild adjustments in driving behaviors and programming could enhance the economy, the question is ... how!

 

You are wanting a system to do something that it was never designed nor programmed to do.

 

Same question here, curious what the charging/discharging algorithm is. Suspecting that overall state of charge is likely a big factor for both regenerative braking and battery assisted acceleration, but algorithm could likely get complicated.

 

Obviously that's not correct, because the hybrid does in fact get better fuel economy. It's an insult to peoples' intelligence to say it doesn't, and to "just drive it." All I want to know is how and when it works.

TL;DR:
“Efficiency was of secondary importance in the design of the i-Force Max (we'll eschew the shout-case from here on). The goal instead was to deliver a diesel like torque curve.”

 

1. toyota has never gone into any detail how the system really switches back and forth between using the hybrid system and not.

they have given a very brief broad overview of how it engages via video's before it came out but i dont think they harped on it in brochures or what not after release.

you would have to search youtube to find some pre release interviews on they hybrid system. your best bet is to rummage thru ADM youtube videos (care car nut)


but the biggest issue i see is that if you are getting the hybrid to save gas, the math really doesnt work in your favor


you pay roughly $3500 more for a hybrid engine

you get best 2 mpg city better than the gas engine (highway you get the same mpg for gas/hybrid)

for argument sake, you use rouhgly 25 gals per tank fill up (roughly leaves 8 gal reserve which should be just above empty and below 1/8 tank left)

per fill up you 50 miles per tank fill up. 50 miles / 20 mpg @ $3.00 gal = you save $7.50 per tank

so to get your return on the $3500 = roughly 466 fill ups. (3500/7.5)

in my case via fuelly stats (in my sig), we have had 66 fill ups in 21 months. so that comes out to 3 fill ups per month = 466 / 3 = 155 months or 12.9 yrs

that is going entirely by paper stats, reality is probably closer to maybe 1 mpg or less above the gas engine.


i am doing back of the napkin math so if someone can explain it better have at it.

 

Add in a my MPG is garbage thread

 

There's plenty of info on the internet about the Tundra Hybrid system ....some of it from Toyota. Why would you come to a forum for owners and look for engineering details is beyond me. And yes it gets better mileage around town but lower on the highway so who's right?

 

So, how slow can you drive to run off the Hybrid battery??????

 

It’s simple. It’s charges when the engine is on or you are coasting or braking. You can play with the throttle to figure out when it will/won’t engage the ICE. It took me a couple of days to figure out how to get it to shut off the ICE while cruising down a flat road at 50mph. Pretty sweet tbh.

 

As slow as you want, but it rarely will kick on over 70 MPH. The Hybrid shine best on around town driving versus long high speed drives.

Correct, when the motor is not running it is getting better MPG....it's a fact. A lot of people are anti hybrid/ anti electrical and will go to no end to convince you as such

 

from what i know the you can only run on pure hybrid under roughly 18 mph, rest of the time it supplements the gas engine

 

The Hybrid getting better MPG is purely anecdotal and was not the primary reason for putting it in the Tundra, Sequoia, or any other Body on Frame vehicle that Toyota/Lexus sells.

 

The penguin is right. Even though the hybrid equipped Tundras achieve better fuel economy, they still don’t!!

 

I'll follow up with a what kind and how often oil thread

 

How about another what side steps/running boards should I get???????

 

I rest my case LOL
