Yea, this is what Abby Grajek, vehicle integration engineer for Ford Maverick said about HF55:   Every component of the new HF55 hybrid transaxle (now used in all Maverick Hybrid versions) is uprated while continuing to fit within the same package size as its predecessor. Torque from the drive motor rises from 235 to 320 Newton-meters (173 to 236 pound-feet), while the generator’s power output goes from 78 to 96 kilowatts (105 to 129 horsepower).    

Yep  

If it's just a story of the first Raptor's "birth", that's kind of anticlimactic and doesn't need a reveal date like that, IMO.....

Didn't realize they were switching but it makes sense to just have 1 version.  Might also signal a future switch to an ecoboost engine.

Putting my old developer hat I can't think of anything that would have to change.  Obviously the engine has it's own software but I don't think the ECVT has to change.  The big change is on the hardware so it can handle the higher torque thus the increase from HF35 to HF45 and HF55.

I got beat up on this already LOL 2025 Ford Maverick Hybrid Features New HF55 Transmission   I'll fix the corsair vs Nautilus 😛  

It's a Nautilus not Corsair and it uses the HF55.  Maverick uses the na 2.5 atkinson with a HF45.

Here is a picture of the steering wheel and a video demo.   https://photos.icloud.com/shared/album/0c0jKtS5oVrqOXiitYYfSSMjw

Its not so much the HP, but the torque. From what I can tell, your Nautilus is using a HF45 and not the 55 in the Maverick.   Plus the Fusion ST and Taurus SHO put 325/380 and 365/350 respectively though the 6F with a FWD bias AWD system  

yep and it also depends to what your listening to.
