Let's be real here. The last thing people want in a Luxo-SUV is a stinkin' and noisy diesel motor. Toyota/Lexus makes these for their upscale buyers, not four-wheelers. Go get a Grand 3.0CRD.
I agree, most luxury suv buyers would prefer a v8 gas and auto.
And the v8 in the 100 is a great one. So if they use that, or a newer version, it would be the best gas motor they could put in.
But Toyota can make quiet, powerful diesels (that don't smoke much).
The diesel in my HDJ81 (1HD-T), was quiet, powerful, and smooth.
If it had an intercooler, it would had a lot more power than the gas v8, and better millage. The HDJ81 was a luxury offroad SUV.
So yeah, I can see them only offering a gas v8 and auto.
I don't think "new" (not used) buyers would want a stick shift.
It's the guys like us that buy them a few years old that want Deisel and 5speeds.
That why we have to import them.
Anywhere else in the world they want diesel (stick or auto based on preference). That also includes the luxury market. Look at Europe and Japan, they still want diesel in the luxury SUVs.
North America will probably get gas only.
Rest of the world will get all the options.
