Any chance the PHEV versions will be somewhat rear wheel biased? Or will the engine only drive the front axle?

In E-Four the ICE also drives the rear axle via the electric pathway. In E-Axle the ability is further increased.Any chance the PHEV versions will be somewhat rear wheel biased? Or will the engine only drive the front axle?

E-Axle would make a lot of difference in cornering. It could send more power to the rear motor to help turn in and more power to the front at exit to straighten out, so it's mechanically equivalent to an AWD system with a center TVD, just more flexible. That's how their LMP1 car works.
So you could have an ICE that's driving AWD, with additional assist to rear from e-axle?

Lexus has trademarked the NX 250 nameplate in the USA, suggesting that a new engine variant is coming to the compact crossover, likely as part of a next-generation model launch.
The powertrain is easy enough to guess — given the NX shares much of its underpinnings with the Toyota RAV4, that model’s A25A-FKS 2.5L four-cylinder engine is the safe bet.
The NX originally launched in 2014, with a mid-cycle refresh happening in 2017. A next-generation model is expected some time in the next year.
(The NX 250 nameplate was filed with the United States Patent and Trademark Office on April 7, 2020 under #88862269. Thanks mwyf!)
If I'm not mistaken the RAV4 E-Four allows direct power transfer from MG1 (generator) to MG3 (rear motor) without going through HVB. Their demonstration video shows MG3 could be powered directly by HVB, this doesn't seem to be true since MG3 doesn't have an independent inverter. Instead it draws power from the central inverter (shared with MG2) in the front. It's different from the Prius/UX E-Four which has a completely independent MG3 that can only draw power from HVB.Well ICE powers battery which then provides power to the rear motors.
What's the 0-60 going to be on this 2.5? Doesn't the current 2.0 get to 7.0 but the current RAV4 go 0-60 in like 8?
It's gonna be pedestrian 0-60 much like RAV4 most likely. Toyota is really not putting emphasis on acceleration with small engines. Biggest offender being 300h, that engine does not like to accelerate so no wonder it's efficient.

A 20:80 distribution could mean 10kW to the front 40kW to the rear. It is not limited by battery power but by motor power.
It can. The HVB will provide power to the central inverter which then sends power to MG3. MG3 shares the electric pathway with MG2 unlike in the Prius E-Four.interesting, so you think MG3 cant be powered with engine off, like Prius/UX can?

Well, unfortunately a 'rear wheel biased' transmission does not solve all issues if the car still remains 'nose heavy'.
Then everything is fine until it is not FWD only.What about a giant flat slab of heavy batteries hung off the bottom of the vehicle?
Yeah is good also they can make a options.
