This is from Toyota JP spec sheet. It seems Toyota is intentionally differentiating Toyota and Lexus. The 2.4T hybrid system in the Crown is called "E-Four Advanced" to indicate it's a middle-ground between E-Four and Direct4. Direct4 will probably be a Lexus exclusive, good news for Lexus buyers.
The difference? The Crown's rear eAxle is detuned from 80kW to 59kW. It is the same 1YM unit used by bZ4X and RX500h just less powerful (torque remains the same). Toyota doesn't show the battery voltage but I suspect the battery is downsized as well.
Also I was wrong about two things in my original RX500h analysis: 1) the front motor is not identical to the rear, it's less powerful but has considerably more torque (61kW/292N.m). In fact, this motor is much more powerful than the 36kW/250N.m unit in the iForce Max and is potentially a future upgrade. The iForce Max would increase from 325kW(437hp)/790N.m(583lb.ft) to 350kW(469hp)/890N.m(656lb.ft). 2) The 6AT is not 8AT with 1st and 8th removed. It still has a 1st gear with a 14.89:1 overall reduction ratio. It just has really wide gear spread.

The 2.4T hybrid system is 150kg/330lbs heavier than the 2.5 hybrid with E-Four. The NX350h is 30kg heavier than the NX350. So the total added weight of 500h vs. 350 (2.4T) is ~180kg/400lbs.
By comparison the last-gen RX450h vs. RX350 is 160kg heavier. Crown 3.5 multi-stage vs. 2.5 hybrid is 130kg heavier.

The interior cabin length is 1980mm. That's 35mm longer than the ES, same as the S220 Crown, 40mm longer than the GS, 70mm shorter than the LS. The packaging is quite efficient.
The ground clearance is only 145mm (5.7 inch), exactly the same as ES and Camry. This is not even a "raised sedan" many suspected. It only looks raised because of the plastic cladding.

I also compared the full equipment list vs. S220 and I did not find features and equipment to be inferior to the S220. So at least on paper it's not a downgrade. But I agree the interior design looks cheap in full black. The S220 interior doesn't feel the same way.
