I get you. And as good as the engine may be, we are living in times where a Full Size three row TX SUV has a F Sport Performance.I don't think a 460hp GX deserves a F name. And I don't think Toyota will experiment with anything more powerful than the 3.4 iForce Max until they are ready to introduce a PHEV version. The battery technology just isn't ready for full-size PHEV trucks yet.
The PHEV will easily have over 600hp but we'll have to wait until at least 2028.
