Which means this could be a PHV-only system.
This is what I am thinking. I believe that the E-Axle would only be available on plug-in hybrid vehicles.

With such a high-power motor driving the rear axle, the traction battery on a normal hybrid vehicle would drain quickly and fuel efficiency would suffer as a result, as the engine would be running more often to keep the battery topped up.

If the driver locks the rear axle, and the ICE turns off, would that mean the ES can be a limited full-electric RWD car?

I was thinking that the E-Axle could also be the basis of a through-the-road (TTR) hybrid system: the front wheels remain driven solely (mechanically) by the ICE, while the rear wheels are driven (electrically) by the E-Axle, similar to the PSA Peugeot-Citroën's HYbrid4 hybrid system used in the Peugeot 3008 HYbrid4. A TTR Hybrid system is an "easy" approach to building a hybrid vehicle, merely by replacing the otherwise non-traction wheels with an electrically-driven axle.

Such a car could start off in RWD EV mode, switch to FWD ICE-driven mode when the traction battery drains (topping up the battery by dragging the rear E-Axle in generator mode and/or the ICE turning a starter-alternator/generator), and switch to AWD hybrid gas-electric mode should the need arise.

I don't see Toyota building a different hybrid system, however, especially one that does not combine a starter-generator and primary traction motor in one combined transmission unit.

My vague uninformed guessing saves the day again.

Excited to see what comes of this, but I imagine the battery pack that supports this sort of use case is a bit different to the standard hybrid setup? Or is that not the case?
Y'ALL SHOULDA FIGURED IT OUT. *angery reacts*

Now I spoon-fed y'all and the suspense is gone. *sad reaccs*


The writing is on the wall and it’s only a matter of time to say goodbye to the GS. I wish Lexus loved you as much as I do. You were the best vehicle I have ever owned. At least you’ll live on as a Toyota Mirai. 😢
I CAME HERE TO BE HAPPY NOT TO FEEL RIGHT NOW. 😭😭

Honestly the thought of not having a GS anymore horrifies me.

The user-operable rear axle 'lock' should be standard on all their E-Four cars. Forcing the rear axle to engage (instead of software telling it to) could help a long way with, say, the RAV4 hybrid in offroad situations.

Would like to see even more power at the rear axle. On top of the A25A-FXS the two would have combined 235kW/315hp which is not a lot for a performance model of ES. Comparable solutions from BYD and Polestar have over 200kW in the rear for combined output of over 400kW. But I guess they don't want weight to get out of control.

On the RX with a 2.5 Turbo the combination could make 300-350kW which would be quite good.

On the LC it just creates a huge traction problem, those poor rear tyres.


Which means this could be a PHV-only system.
Who says it can't be used on the front axle either? I have said this for so long but everyone in this forum ignored me.

Think about a badass race car that Toyota is competing with right now.

That is your answer......

Does this have something to do with the Toyota Hybrid System-Racing from their Le Mans hybrid racecar / Toyota GR Super Sport Concept?


I think on the motorsport front they are going Supra too, right?

EDIT:

Hmm, so the GS450h in '06 was actually the first racing hybrid system, so it partly started in Lexus.

This:

Seems to show it can be on either axle or both, but I have no idea if this is the same sort of technology being talked about here.

This:

Seems to show their ideas about in-wheel motors going back to their '07 Supra.

Sorry, more vague guessing from me, but this is very interesting.

You got it, and it's what I have been saying for the past 567.3 years.

And yeah, they're starting to go crazy with the Supra in Europe and the rest of the world when it comes to racing.

I guess they won't put it that way in ES / Avalon / Camry

I think it will be either Highlander / RX system as they share with them the same architecture or the electric AWD found in the new Rav4
