Hybrid mpg

I’ve been getting 20-22 every time I drive my truck to work. 50 mile trip each way, mostly rural roads 55-60 MPH. 22 Limited 4x4

I get 17-19 if I drive like a teenager borrowing dads truck while driving around my small beach town.

 

Anyone else surprised there haven't been any further leaks regarding the iForce Max's fuel economy?

 

K, hear me out. I have no proof, no rumors, no “insider knowledge” just an idea…
The 2022 hybrid numbers are weak sauce because Toyota is still doing R&D on their “real” world beater hybrid.

2025 Tundra Prime. (Plug in)

Upgraded battery from nicad to lithium ion or better. 7.4kwh or more.

Electric only range of 15-25 miles.

Choosable modes elec only, eco, power or sport.

Current setup is for power when towing to give better overall mpg. 2025 setup is doable, in line with electrification goals. CAFe standards and people progressing to plug in.
Gasoline is also very likely to be $6/gal here in CA.
In all honesty, I can see the after market companies stepping up to upgrade battery packs and offer “tuning” for mpgs.

I had planned to order a TRD Pro or 4x4 Platinum hybrid this April for me birthday present & side biz investment.
Not so sure now since payment free is a truly a wonderful feeling.
Plus my 2017 audio upgrade is happening next month.

 

I read your post and then I looked at your avatar…I’m not sure how to feel about your “ideas.”

 

LOL.

IM not sure about you R&D comment. They just went with the cheap and available batteries. I hope they upgrade them and provide other options by the time the 2024s come out. Solid state batteries would awesome but a dream for 2024.

 

According to this TFL video at 11:40, fuel efficiency for hybrids will be released February 1st.

 

Would rather be disappointed now than later, come on Toyota.

 

the highlander has the same size of battery as the tundra. obviously the highlander is smaller and is optimized for mpg.
it goes from 21/29 mpg to 36/35 hybrid. Tundra is 18/23, I expect the hybrid to be somewhere around 25/24. Hopefully 26/25 and I'm sold.

 

Highlander is a parallel-series hybrid which is way more efficient than a parallel hybrid like the Tundra. The leaked 21-22 mpg combined seems more likely in my opinion. The big improvement will definitely be city mpg.

 

You can't compare the standard Highlander hybrid to the non-hybrid and project MPG gains to Tundra on that ratio because the standard 'Lander is a V-6 with multi speed trans and the 'Lander hybrid has a much smaller 4 cylinder engine and CVT. So it's base MPG would have been a lot better already without the hybrid setup. IOW you can't use a similar multiplier for Tundra that has the same ICE powerplant for its hybrid version. Tundra MPG gains will be minimal.

 

I'm calling 21mpg combined for the iForce Max.

 

Same but only the pro, 23 combined for other trims.

 

That'd be my ~guess, too. But just a guess.

 

The EPA would only have to rate the 2WD and 4WD versions of the iForce Max though, wouldn't they? Or have I forgotten, and every hybrid Tundra comes as a 4WD only?

 

TRD Jon says mpg coming Feb 1 also.

There’s 2WD iforce max. I think there will be separate ratings for Pro, non-pro 4WD, and 2WD.

 

I thought so. Thanks. But, I didn't think the EPA reported fuel economy for every single model of passenger vehicles and light trucks. I think the manufacturer only submits the fuel economy for their most fuel efficient 2WD then 4WD. I know that they only publish 2WD and 4WD fuel economy for the iForce (non-hybrid).

 

I was in a similar boat, go for the 2022 or stick with the 2021. The break even point on cost is why I went with the 2021 model. Granted I got mine for 1k off MSRP and assuming the 2022s would as well (but I’m our current situation no guarantee’s). Averaging 10k miles per year means that the 2022 saves around 240gal vs the 2021. Average the cost of gas around $4/gal you get about $950. Since the 2022’s are averaging $12.5k more expensive per the dealership near me. Means that the break even point where the 2022s save you money from the fuel economy is about 13 years. So for my money I went with the immediate savings (and some other reasons) of the 2021.

Long story short, if money is the deciding factor I think it’s the smart choice to take the immediate savings or at least give it a consideration when making your decision

 

Is there any other way to drive?

 

They don’t but when there’s enough of a difference the manufacturers have to show fuel economy numbers for specific trims. For example, F150 Tremor, Silverado AT4, RAM HFE.

 

Oh, OK. I did not know that. Thanks bud!

 

Good info on the Highlander but I'm still sticking to my 25/24 prediction on the Tundra. Look the highway miles or 23 already, there will be a bump there because even in a highway test the truck will use the electric motor from 0 - 18 MPG. City miles is where most of the improvement will come. 23/24 at the very least.

 

Do you mean 0-18 mph? The truck can use the electric motor at any speed and it acts to fill in torque when required. I’ve read some Toyota information that says it will run on electric only up to 18 mph, maybe that’s what you’re referring to, but that seems wrong to me honestly. It could probably cruise up to 35 or 40 mph in electric alone but only for a short distance. From personal experience, F150 Powerboost can maintain 50 mph on flat road in electric only mode.

 

25/24 maybe possible. But you just have to wonder how much can be done with such a small (~18KWh IIRC) cheap metal hydride battery in a 6000 pound truck. This is a mild hybrid and the battery is sooo small that it can only provide boost for so long... and not long... before the system needs to recharge it somehow whether under braking or not. For instance the e-bike I built has a 1.2 KWh battery (although only 52V) and me and it weigh about 75 pounds all in. But I'll take any MPG it can give, that is if the cost doesn't totally erase any fuel savings.

 

Lol dude both F150 and Tundra have less than 2kWh battery. F150 is 1.5 kWh and Tundra is 1.9 kWh.

Ain’t no way possible the Tundra can beat the F150 numbers. The main reason is the F150 is so much lighter than the Tundra. That pays huge dividends in the way the EPA certifies fuel economy.

 

LOL... my failing memory had that battery capacity off by a factor of 10! Tiny battery indeed.

 

I think Prius is even smaller. Then you have Hummer EV with 200 kWh and only 300 mi range (@9000lbs vehicle weight)

 

Those BEV batteries are lithium but I am not sure about the Prius hybrid. Although the Prius plug in version almost certainly is Li and much bigger than the plain hybrid model. I'd really like to see a plug-in hybrid Tacoma.

As for the Tundra... As a baseline I'd go do the math to see how long its 1.9KWh battery will run the ~50 HP electric motor at full power. But no need. The answer is simply "not very long".

 

I'd have to check the owner's manual, but I think our 2017 Prius (non-Prime) has a 0.75kwh hybrid battery. As I understand it, it's a different system than the Tundra iForce Max hybrid, but the Prius will operate in EV only mode up to approximately 32km/h (20 mph) if the battery has sufficient charge and the ICE is not required for demanded acceleration or grade.
Since they've mentioned that you can maneuver the iForce Max via the hybrid battery, I'd imagine you could drive slowly down the street, in or out of your garage or around a parking lot up to 18 mph without the ICE starting.

 

I had a Prius rental once on a business trip and was thoroughly impressed. Unbelievable MPG. And the driving experience was fine.
