After seeing some internet rumors about HD Tundras, some with Cummins V8 diesels, DRWs, etc, I'm wondering: Do you know anything official from Toyota? Do you have a link?
It's been discussed cause there has been some hopes that they will make a 3/4 ton truck. Have never seen any articles to say for sure just rumors out there. Somebody might have more info, if so hope they share. With the new Nissan with diesel coming out, that may prompt Toyota to make one but who knows.
I've not seen anything solid about a HD Toyota, just the Nissan. The regular Tundra is among the lighter half tons so it would take some big changes to massage it into a true HD model.
Google 5.0 Cummins V8 Toyota and you will find a number of reports that state it will be offered in 2016. I am almost positive I read a formal announcement in the past, but can't find it now. All the articles seem to be from early 2014.
I watched a video on the Cummins V8 and two negatives stood out to me - it uses a CP4 injection pump and it has a timing chain instead of a gear setup.
Other than those issues it's a really appealing powerplant that offers plenty of power and probably pretty good fuel economy. Those issues would give me pause, though.
I have been hearing those HD Tundra rumors for about 5 years now. I haven't seen anything to make me believe that they are offering a heavier duty truck. I couldn't wait any longer, had to sell my Tundra and pick up a heavier truck for my new camper.
If they do it I certainly hope they have figured out how to get some payload. I've been saying for a long time a more reasonably sized/priced diesel option would lead to more sales than the monster diesel motors they are making now but then I'm in a manfacturing job in an unrelated industry.
I can't think of anyone that would want a "tractor engine" in their truck:B
Funny that Nissan has a Cummins and Toyota is possibly going to go to one, BUT, Ram opted for a different diesel engine, rather than the V-8 Cummins to be put in their 1500:h
I think the Ram 1500 engine choice was due to availability within FCA plus the smaller Eco fit more platforms (Jeep). I'm sure there is a bigger profit margin by staying in house with the engine too.
Best I can assume while following this closely, is that Toyota will likely have an all new Tundra in 2017/2018 and practically match what Nissan has done.
I think Toyota will offer a diesel engine and add an optional designation of "HD" to higher capacity rated trucks. And it sounds like the engine is practically identical to Nissan's...I have no resource for this. But it sure would be smart to help raise production volume and lower costs.
I see no indication of DRW. Those are pics from a 2007/2008 prototype, just before the project was killed due to the depression.
