Toyota Tundra to Get Cummins Diesel V-8

Toyota Tundra to Get Cummins Diesel V-8 – News – Car and Driver | Car and Driver Blog

Thought I create a new thread for this topic.

In my opinion, Toyota reliability + Cummins Diesel would make for a great pickup -- Only if they increase the payload a bit more.

Also, Toyota is the only manufacturer that has implemented SAE standards for tow ratings.

I never understood the problem introducing a diesel into a small pickup in the US. They are all over Europe and the rest of the world. Must be a pollution EPA thing. Anyway, the next few years are going to be interesting for pickup design. We should definitely start seeing better MPG in the tow rating needed. Right now it looks like 12 MPG while towing is pretty much the norm.

Agree with DryFly .Just got back from Australia and a New Zealand. They had the Toyota HiLux w/Diesel. Awesome . Diesel was the majority of vehicles ,and it was cheaper price than Gas. The variety of campers they had was incredible. Smaller driving units and Bus style campers with Toyota,Fuso,Fiat ,Izuzu,Nissan,VW,Etc. Jayco had Euro style trailers i have not seen here. New Zealand is a campers paradise !
I have not been a fan of Diesel until now. How did we get started with Gas instead of Diesel? Just curious .No Flame or Politics implied.

Vanderbilts and Rockefellers killed diesel in the early 1900's because they had oil and transportation for the oil.... Henry Ford is reputed to have initially been a fan of diesel. Then, in the 1970's the next nail in the coffin was laid when GM modified a gasoline engine for diesel that didn't deliver how shall we say....stellar performance.

Admittedly, I am not a big foreign car fan, but I welcome this news. I think that an efficient diesel engine in a half ton pick-up will encourage Ford and GM to follow suit if they want to remain competitive.

I think the big reason was cost, they wanted to be competitive in pricing with GM and Ford trucks, which had the lion's share of the truck market. A diesel engine would widen the price gap more than they would like.

Toyota has several gas engine manufacturing facilities in the US, none for diesel. Just a guess, but I'd say they've been negotiating, testing, etc. with various diesel manufacturers for a while. Toyota suppliers have to meet some rigorous specifications, very low defect rates and agree to meet the necessary 'just in time' delivery schedule with an approved manual backup plan.

Finally, Toyota is slow to make big changes, they prefer to 'tweak' their designs. Their pickups have evolved from the generic, no name pickup to Tacoma, to the grossly underpowered T-100 and finally Tundra, which has been increasing in size since its inception.

After working for them for 16 years I can tell you, Toyota is not interested in being first, they want to be the best.

It seems to me that a Toyota diesel would be s Hino. Isn't Hino a division of Toyota. I remember seeing a YouTube video about a prototype Tundra diesel with a Hino 6 cylinder. I have heard some hearsay rumours of the Nissan Titan getting a Cummins.

Now maybe if Toyota can beef up their frames they can tow their own trucks around. We'll see...

IMHO it will be a cold day in hell before Toyota puts a Cummins or any NA diesel in its pick ups. Japanese diesels are light years ahead of NA diesels in quality, filtration and durability. Heck the Isuzu diesel in my 310, a 30+ year old engine doesn't even require the use of glow plugs to get going in temps over 40F. If my Isuzu flywheel turns more than 1/4 turn before lighting up I'm surprised.

It would be a Hino diesel just like the 3.4L Hino 4 cly diesel in my 1984 BJ 60 Toyota Landcruiser.

Also FYI, I would also be very shocked if it were to be a V8. V8 diesels are notoriously poor, see pretty well every GM diesel and more than a few Fords..and yes they were made at a Duramax plant by Isuzu which GM part owns, BUT GM engines are designed by GM, not Isuzu. Isuzu would never make a V diesel themselves.

Hino Motors makes large delivery type trucks, like 6-wheel and up. Toyota owns or owned an interest in them. I'm not sure where they stand now. I know there's a relationship of some sort. Hino has a presence in the US but I think all the vehicles are made in Japan and shipped here.

I followed that earlier link and there was something about Nissan putting the Cummins in their pickup also; 500 ft lbs. of torque - woof! But will the ride be soft enough for Airstreams???

Not according to Wards Auto:
Toyota Tundra Set to Receive Cummins Diesel | Vehicles & Technology content from WardsAuto

My guess is they will start out with Cummins but eventually replace it with their own version. The article says they've been working with Hino on developing a diesel but stopped. Toyota may elect to restart the program. I can't find anything official from Toyota but there probably won't be anything for a while.

Okay I give.Hell has started to freeze over.

But what a bone headed move.Why come out with the exact same as your competition??? It doesn't make sense for them to copy cat what Ram,GM and Ford are doing.

If they come out with a V8 Toyota truck with a Cummins, it just shows that Toyota doesn't think with innovation anymore.

Inquiring Minds Want To Know

Maybe its because the USA made Cummins is a good product?

I would think a 6 cylinder diesel would do it, but who knows?
The result of the Hino diesel Tundra prototype back in 2008 + the bad economy was nothing.
Maybe it is all just hype and rumors now.
The logic of why Nissan would have a Cummins eludes me, too, but I have heard that Ram is going to an Italian made diesel-
