Honda HEVF e-CVT fluid

[brages]

Noticed that Honda has a new transmission fluid that is specifically for their latest hybrids: Honda HEVF Type 1.0. Part number 08200-9022.

Any idea what's in this stuff?

My hybrid is a 2019, so I am supposed to use DW-1. I just wondered how this new fluid might be better or if it could even be backwards compatible (seems like it isn't).

Don't know how much they'd change the clutch characteristics in the new honda ecvt or if they updated the new ecvt to not have a clutch anymore. Honda's ecvt or at least the older one does have a clutch unlike toyota's ecvt but both are geared not belt or chain.

It sounds a whole lot like Toyota’s new e-Transaxle TE fluid, an ultra-low viscosity oil. But Honda’s new system is a serial hybrid system - the engine drives a motor/generator which in turns drives another motor/generator. The latest version includes a clutch to allow direct drive by the ICE but not like the Toyota parallel-split system that uses a planetary gear to blend the power sources.

They moved the electric motors side-by-side, rather than in line. Except in the Civic, where they kept them in line. I think the motors are slightly changed as well.

The CR-V has two clutches (don't know if that's new). Accord and Civic still have one. They added fake shifts, but I imagine that's all done in software.
