I was just in Plano last week and have a few friends around. Whether its legit or not I was told to NEVER expect a diesel 4R in the states...

If Toyota were ever to introduce a diesel in the US, I'm fairly confident the first vehicle to get one would be the Tundra (and ergo, possibly the Sequoia). Other than the small percentage of us here who'd want one, there's no market for a diesel 4Runner whereas a diesel Tundra could take a decent chunk of the full-size truck market. The vast majority of 4Runner buyers are soccer moms who don't want a full on minivan look.

You're dang right.
I've talked with the Cummins guys a few times about doing a R2.8 swap. Probably going to wait until I finish my build and then attempt it.

A D44 will never be as strong as a current Toyota ifs. The physical limitation on joint space limits the d44. It's an inherently weak front axle.
I wouldn't! :happy:
If a diesel ends up in the 4Runner, it sure won't be the 1VD-FTV. Maybe the 1GD-FTV. I'd expect ocean front property in Iowa before I'd expect a 1VD-FTV in the 4Runner.
All the hundreds of thousands of LC's in the Middle East would disagree with that. They run the heck out of them. I saw 2 year old LC's for sale in Qatar with 100,000 miles(160k km) on them, in a country the size of Connecticut.
One of my favorite vehicles was a suburban diesel. Super reliable, low up keep, I loved it.
My least favorite vehicle was the 2015 Jeep Grand Cherokee diesel I just turned it. A modern diesel comes with DEF fluid, recovery cycles and extraneous maintenance. It really only starts to make sense when you’re driving 60k miles a year.
It is unlikely we will see a diesel 4runner due to emissions regulations.

remember the cat powered tundra that was supposed to come out?
It totally would have, if the historically large economic recovery and low gas prices could have been predicted.
My feeling is that Toyota has always been very close to pulling the trigger on a lot of upgrades/changes, but they've pushed it off as far as possible since gas prices (until recently) haven't really gone high enough to be a buying consideration for buyers.
That said, now they're starting to climb, and the recovery seems to be in its last days. Combine that with brand new offerings from a lot of competitors, and it looks to me like they will have to throw some big budget at the 4Runner.
My bold predictions:
-No next Land Cruiser.
-Instead, the "Land Cruiser" will be a halo-trim/powertrain version of the 6th gen 4Runner with unique body and suspension over the same chassis.
-If this happens, it COULD explain the rumors of the 4.5L turbodiesel V8. Meaning, it could end up in a 6th gen chassis, but at a price point that will be $60,000+
-The lower-tier 6th gens will get a reworked 3.5L and/or a smaller 4-cylinder turbo (like Chevy did with the 2.7T), slight aero improvements, an 8 or 10 speed auto, and some use of aluminum and more plastic to reduce weight.

Toyota is working on a new global BOF architecture. So it's all but certain the next tundra, Land Cruiser, and 150 series replacement will all share a platform. The 150 is likely the last to hit production of the group.
The 150 already has the 3.5 6AT combo in China and other markets. A refresh with that combo is all but certain. If we're really lucky we'll get the 3.5 and 8AT or a turbo 4 with an 8AT. Otherwise - there's no reason to change much of anything. It works, it sells, it's actually pretty cheap compared to anything else out there.
My bet is that the Tundra will get the Cummins 5.0 in the next iteration. In the real next gen 4Runner in 202x the 4Runner gets a mild hybrid and 3.5L ish engine. I don't think there will be more than another 10-15 years of ICE engines in new vehicles. So I'm highly skeptical of any claim of Toyota developing a new diesel that's anything other than a slight tweak of existing ones, or outsourcing. I don't see any reason to spend the time or $ on USA emissions development. The Cummins 5.0 is ready to go with EPA already sorted out. The only small motor is the VM Motori 2.8 used in Jeep and GM Colorado. It's not great motor so far. It was a terrible motor in the Jeep Liberty in the earlier model of the engine. I don't think Toyota would try it.

I wish Kubota would build a diesel for the Tundra, that would be awesome.

Toyota uses Volvo diesel engines in it's larger boats. Toyota actually has a fairly successful fishing boat program in Asia. Some of Volvo's diesel engines are pretty nice too. The other one is the Hino 5 and 6cyl engines. They have a 5cyl inline diesel that's ~300hp that would be really nice in a Tundra if the NVH is sorted out. But the EPA costs pretty much kill all of those ideas.
Maybe the Cummins 2.8? It's the only other EPA approved small diesel I know of.
All seems plausibe -- just that the 4.5L turbodiesel v8 is an old engine, not new. So could see it being the top engine offered in both the Tundra and Land Cruiser or top level 4Runner for a few years.
No shortage of tire discussions here for you to explore. I've had Firestone Destination A/Ts and Cooper Discoverer AT/3s that both worked great and aren't as beefy (my opinion) as the KO2s. Run your OEM tires until they're cooked and decide for yourself....
