Hino Powertrains Could Motivate Toyota Tundra


Hino Trucks, a Toyota Group Co., is celebrating 30 years in the medium-duty truck business here in the U.S. It now has more than 200 dealers across the country. Hino Trucks has offered commercial trucks from Class 4 to Class 7 products, the most popular being the Class 5 COE (cab over engine) regular and double-cab models; they even come in regular diesel and diesel hybrid configurations.

The COE trucks have been in PickupTrucks.com news for several years because of their 5.0-liter inline-four-cylinder hybrid powertrain technology that some predicted would be made available in the redesigned 2014 Tundra. A Hino 8.0-liter inline-six-cylinder powertrain was under the hood of the popular pickup truck concept, the Tundra Dually Diesel CrewMax, from 2007 and garnered a boat-load of attention at the Specialty Equipment Market Association Show. Unfortunately, the big concept truck's timing could not have been worse as pickup sales (and the economy) over the next few years went from bad to worse.

Although no confirmation has come from Toyota, rumors are flying about the truckmaker possibly using the same Cummins turbo-diesel 5.0-liter V-8 that will show up in the coming 2016 Nissan Titan. "Borrowing" the Cummins does seem slightly odd given the variety of Hino diesel engines the full-size pickup could use, which makes us think other drivability issues may be biggest problem, namely finding a six- or eight-speed automatic transmission strong and smooth enough to deal with the torque-growing payload and towing requirements. Either way, it will be interesting to see if Tundra (or Tacoma) decide to leverage some of the Hino powertrain credibility (hybrid or not) to meet the more aggressive upcoming EPA fuel-economy targets.

Tundra dually II

Tundra Dually engine





Just do it! Toyota.

And there is also the Hi Lux Turbo Diesel. A great truck for Special Ops.


@papa jim, Does the Tundra team need a motivational speaker? Is this one of those slow news day stories?

Where is the 400hp Valvematic 5.0 V8 + 8 speed automatic at?
What about 300hp Valvematic 3.5 V6 + 8 speed auto?
Get those two first, then think about a diesel.

And there is also the Hi Lux Turbo Diesel. A great truck for Special Ops.

And special price. 60 000AUD.

its actaully looks cool :')

I disagree that dually is hideous.

According to most Tundra owners it's really a 3/4 ton truck. A diesel option would just confirm their delusions.

If it were like the SEMA concept, that would be good. But it will never happen. The best realistic chance for a Tundra diesel is the Cummins ISV 5.0 on the same flimsy 1/2-ton frame. Dale Milner is absolutely spot on!

Why not a Tacoma dually with a 4cyl gas motor...

If the tundra is a 3/4 ton then the 2015 f150 is a one ton. Maybe even 1-1/4 ton.

@Wolfgang. LOL!!! What is the F-350? F-750? :)

Too many forward looking statements on this site.

Sure Toyota *COULD* use an engine from a Hino.
Toyota COULD do a lot of things.

But it ain't new until it's happening. Until then, it's just clickbait.

Isn't Ford still using the cute 8.8" rear axle on the F150--I think my little brother had one of those on his Ranger, lol.

Go compare the axles, bearings, etc., of a Tundra to an F150... . I wouldn't claim the Tundra is a 3/4 ton, but it is build pretty heavy for a 1/2 ton.

I don't trade/sell vehicles like most folks do, but if there was a Hino powered Tundra, I'd take a strong look.

Dunno Dav, I am pretty sure my 2005 5.4 XLT has a 9.5'' axle. If they still offer the 8.8'' it's probably on the base engine.

There are two different 8.8 rear ends. One with a 28 spline axle and one with a 31 spine axle.

The 31 spline axle can handle up to 400lbs of torque which is why ford uses it some of their mustangs.

The 28 spline axle can handle 300lbs and was found on the lighter duty rangers and is best avoided.

9.75" 12 bolt in mine. the front is a 8.8" they use the 8.8 as a rear? sounds dumb to me...

the ram uses a 235mm which converts to a 9.25 from what i have read.

page 96 will show some axle specs for for alot of other specs in there too.


GM sued for $10 BILLION cause of the lower resale value of their vehicles cause of the ign switch recall.

ya the 2015 f150s can also carry 3300 lbs in the box. more than a ram or chevy 2500.

So tell me Wolfgang, just what weighs 3,300 pounds that you would be able to put in the back of a F150?

Then if you can find something please post some photos of multiple trucks out in the real world doing that.

If you need to carry 3,300 pounds in the bed of a pick up you need a 3/4 ton or better yet a 1 ton truck.

Ford can make all the payload claims they want but that is not how people use these trucks. So if you have to have that phony number to make your manhood what does that really say about you?

At Brandon d Ram went to a 235 metric axle in 2011. I have one. The downside is no one makes a locker or LS type of diff. for this truck. I checked, you're stuck with the factory LS and open front diff. Good thing I got 4wd. LS does work pretty good tho.

If Toyota does do a heavier version of the Tundra it will be using the new 5litre Cummins and associated powertrain.
Rumours are flying about that Toyota will be using the combination, instead of a modified Hino, a lot cheaper in the long run

If Ford does do a heavier version of the Super Dooty it will necessitate using the new 5litre toilet plunger and associated tools for the job.
Rumours are flying that the Super Dooty will be clogging the john, instead of a modified outhouse, a lot cheaper in the long run

@ toycrusher

"Why not a Tacoma dually with a 4cyl gas motor..."

Don't forget the 10 lug wheels.

If Toyota were to put a Cummins in the Tundra, fiat ram HD sales would plummet, most likely because a Cummins would now be in a Real, Reliable truck.

The Ford 8.8" is actually the redesigned or replacement for the old Ford 9". They are actually a good design and are quite strong.

The size of the diff, especially in a pickup is of little relevance. People will use this as a debating point. Your argument is akin to arguing over acceleration times and so on. It's of little value in this particular debate.

I have a 8.8" E locker in the back of my pickup and it does a really great job.

I don't foresee Toyota using a Hino diesel in the Tundra. A Hino diesel is a different diesel than the lighter duty PowerStrokes and ISV Cummins.

I'm not stating that the PowerStrokes and the new Cummins are not good. They are similar to the VM in the Ram as they are not designed for 24/7 operation.

Hino diesels have much longer life cycles and will out live the Tundra twofold. Why make a product more expensive with an engine that isn't necessary.

The ISV Cummins I'd bet will go into the Tundra. Cummins need to manufacture a significant number of them to keep them in production.

For the Idiot "Dav" that posted the 8.8 is a weak Ford rear or whatever dif...It's stronger than the old 9" and much better than anything here from Toyota...Poser Truck manufacture.

Don't compare an F150 to your at least 10 Year old version of a truck...you need to change and improve...,not just reskin and call it all new LOLOLOL Clowns

That Hino 4cyl is too big an heavy. The Tundra was designed to to package a V8. The Ram had to be designed around that MD engine it has.
@Ram Bighorn 1500- I delivered salt for a little while- we would load a 2500# skid NaCL plus some KCl- over 3000# any day of the week- if you can buy an F150 instead of a 250- it saves everywhere. Fuel, insurance and purchase price, not to mention being easier o climb in and out id, if it's 4wd.

I'm skeptical of Toyota offering any diesel in the near future and even then, the most likely would be something for the class 2a Tundra.

As with everything in the auto industry, there has to be a business case for Toyota to offer a diesel as well as move forward with any type of HD Tundra.

I don't think Toyota has a good business case for either of those as their current Tundra is struggling to retain what little market share it has.

Throwing a Cummins into a truck doesn't mean it's going to sell well. It took the '94 redesign of the Dodge Ram to really get sales going, it wasn't so much the addition of the Cummins option in 1989.

Similarly, Toyota and Nissan need to really think about reasons their current trucks aren't selling well and address those issues.

"meet the more aggressive upcoming EPA fuel-economy targets."

Right. Because they are only selling ten 50-mpg Prius for every Tundra, not counting the Camry, Corolla, and Yaris. The Tundra could get 4 mpg and Toyota would still have no worries meeting CAFE.

. The toyota is a tapered bearing . I would much rather have a tapered bearing design than a c clip

The 8.8 is a c clip design. The 9 inch is tapered bearing. They went to the 8.8 because it was cheaper to make.
I would much rather have the tapered bearing

Big horn ram, I regularly load my 2012 f150 with huge amounts of weight, whether it be rocks or wood or whatever. Ive had it prwtty sagged out. The max payload is a major factor for me in buying a truck. I also done want a 3/4 ton necessarily because they're harder on fuel and slower unloaded. Ford also seems to have best ground clear encephalitis from the factory and can fit a 33" 285 tire with no rubbing. Prob ram could fit those too but not GM.

Man am I drunk? Stupid autocorrect. ..

Your comment regarding the tapered bearing design as a preference over a 'C' Clip design is ambiguous.

Can you explain why there is a difference in the two.

@ Al

I am not "arguing" about anything--I thought that axle strength is something fundamental to a "truck." I hope you understand that axles are typically discussed and "named" by their diff size.

I have owned Fords with both 8.8" and 9" axles--and 8.8" in a Mustang as well. The axle did fine in a 3100 lb car. I actually had the the 8.8 diff fail in my 1/2 ton Ford. But the whole point of my post was geared at folks bashing the Tundra and claiming the F150 has heavier duty components--the opposite is actually true when comparing many of the parts that count.

So are you buddylam??

Seems to be.

What F-150 did you have?

To find out what rear axle you have on your F-150 count the bolts on the diff cover.
12 bolts - 9.75
10 bolts - 8.8
If you have a F-150 with a heavy payload package you have the 9.75
The 3.73 ratio and up is always the 9.75
All Super Crew have the 9.75

They stopped using the tapered bearing in 1986, all axles use a centric cylindrical roller bearing.
Nobody makes a better rear axle than Ford. Even the smaller 8.8 axle is more heavy duty than any axle Ram, Chevy, or Toyota makes.
That is one of the F-150's advantages.
Ford always did have the reputation for the bestest rear axle.
Ram has the worst reputation for weak drivelines cause they are not heavy enough to match the power of the Hemi and burning tire all the time is hard on the driveline. Where the F-150 is too underpowered to burn tire.
What I'm saying is the Ram rear axle may not be that bad, but the way guys show off and burn tire all the time will cause problems at the same time the Ford can't burn tire and that's one of the reasons why there are never any problems with the Ford rear axle.
I understand the power of that Hemi can't be locked up, it has to be free and that temptation is always there. But control yourself and think about how you are abusing your precious Ram!

This issue was raised in Feb this. Year on the Wards site. So it is fairly old news

We have already ascertained that buddylam/Dav has a 8.8.

What I interested in knowing is the year and model of his F-150.

Dang, Al is one paraniod dude--I am not buddylam and I no longer have a Ford at all. I have a Tundra. I don't think I am going to bother responding to a guy that accuses nearly EVERYONE of being someone else and thinks there is some great conspiracy--that only he (of course) should moderate.

buddylam must have the 7th generation (1980-1986) F-150
The 8.8 axle was first used in the 1983 F-150's it replaced the 9" axle.
The 8.8 is the same axle used today with some changes such as the design of the axle bearings.
The 8.8 always had a bullet-proof reputation for reliability.

I was just informing the people that own a F-150 some information of what axle they have in their truck. It doesn't make it any better if you have a 8.8 or a 9.5 they are both reliable.
I would estimate that 80% of the regular readers of PUTC are F-150 owners and this story about a 3/4 ton Toyota isn't interesting to anyone so just living it up a bit by going off the subject.

Remember if you want me to respond respectfully you can address me by my name and not BAFO.

It is rare to hear of problems with Ford rear axles or diffs. Toyota builds reliable stuff. Their trucks tend to rate highest on any dependability survey.
@Tom#3 - Ram has similar power levels to Ford and GM. As you have pointed out, Ram does not have a good reputation for reliable drive trains. That also explains for the most part why their cargo ratings suck.

@ Raven

You crack me up......... The Toyota axles are BULLITPROOF! Dont believe me ask ANYONE who goes wheelin....... they will use 40's on trucks with STOCK axles and still have a tough time breaking them!

For everyone else YACKING about rear diffs......... the Ford 8.8 is WEAK when you compare it to the full welded Axle of a Toyota Tundra that sports a 10.5 inch ring gear....... OH thats right the same size ring gear as an F350 Dually.............

Matter of fact lets one up that the ONLY truck with a larger rear diff is the dually Ram 3500 with an 11.5 diff......... So that makes the Tundra rear diff stronger, PERIOD. No half ton comes close in rear diff strength. name just one person that has broken one? ................................. crickets

Anyone who thinks toyotas are bulletproof is delusional. Second least reliable vehicle I've owned was a toyota. I've seen toyota rear axle bearing problems. Heck, their frames even rotted away. Said it before, I see old American iron all the time, where are the old jap vehicles. Hint, inside new jap vehicles.
