2025 Maverick Hybrid HF55 Transaxle Info (nice write up)

[ListedGuru]

Not sure if this was previously posted here (if so my apologies) but a big shout out to @Proflig8tor for mentioning this article in wired magazine regarding the new HF55 Hybrid Transaxle in the 2025 Maverick Hybrids. Hopefully you can pull up the article and read it here:

https://www.wired.com/story/first-d...-pickup-way-more-americans-should-be-driving/

Some info from the piece I thought was interesting:

"To deliver that performance, 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)."

"The new motors, combined with an essentially unchanged 2.5-liter Atkinson Cycle inline-4, boosts maximum powertrain output to 142 kW (191 hp) at (an unspecified) peak battery output. The hybrid engine turns out to run cooler overall (likely due to the added power supplied by the traction motor), meaning it delivers better cooling performance, even when towing, than the 2.0-liter turbo alternative: Grajek noted that even with the 4K package, Maverick Hybrids retained the standard radiator rather than the uprated version required for the turbo powertrain."

"For better off-the-line performance, the rear axle ratio is raised to 3.37:1 from 2.91:1. Despite that, on-road performance improves: Ford says the 0-to-60-mph acceleration time is cut by 18 percent to 6.8 seconds, while a critical highway-passing-time metric improves roughly 10 percent."

Lots more good information in the full article so enjoy!

Interesting.

So the effect of regen being too much for the battery already, which didn't change in size, is now that more regen is possible.

So now the engine will be spun up even more often to waste electricity on long regen scenarios.

I wonder if they improved the battery to accept that higher kW, along with wires to conduct it?

Interesting the HP didn't increased when combined.
But since combined torque before was 245, and motor is already at 236 on it's own, new combined should be interesting.
Someone with Scantool or Forscan on the 25MY can at least find out what Ford put into the system for what they think it is.

Thanks for article.

2028 will be hybrid only as sole power plant? Any takers?

Sounds like a home run for the 2025's!

Makes sense.. I can also see it going into the next gen Bronco Sport.

That did not work in Chrome for me, or Reader mode. However, we can still listen to the article.

Don't know that they would have made the changes to the EcoBoost for MY2025 if they intended to scrap it for Maverick/BroncoSport in MY2028.

However, I do suspect the Hybrid will continue to improve, it will get better and that battery capacity will increase as well as packaging/cooling improvements are realized.

I'm looking forward to continued feedback from those who have the Hybrid/AWD/4K tow combination over the next year or so. I figured they would sell every one they could produce, but honestly I haven't heard too many hybrid owners who purchased AWD also purchasing the 4Ktow...

I've yet to tow anything greater than 2klbs... Though, on Friday I had about 600lbs in the bed, Wife pets, and few things in the cabin, while towing roughly 2k lbs (estimate, but it was a very heavy load, but fortunately a low frontal area) .... 9 hour trip, 65 to 70mph, 90degF temps. Averaged between 21 and 22mpg...

Good article on the Mav and great details on the HF55.

I like that they have beefed everything up. This is good stuff!

I suspect that the larger generator motor allows for the Maverick to enter into electric mode more often but the 1.1kwh battery limits how long one can remain in electric only. So even if it is regenerating faster, it in turn can stay in electric with increased power instead of needing the ice engine.

That's why I was wondering about cabling, or battery improvements.

Current situation is battery max charge 32 kW, max discharge 27 kW.
On a 94 kW motor. So full motor power comes with ICE providing more electric.
(those are in PIDs too, so again scanner/Forscan with 25MY would spell it out)

If I could just see 15% power allowed in EV mode instead of 10%, I'd have many more inclines and starts from a light where I could stay in EV.
Sure it would be shorter time, but in the many spots I see, truck will need the ICE anyway pretty quickly.

Now this should be simple test for someone with 25MY, if gentle on Go pedal, does ICE still kick in about 10%.

Also considering motor power from battery is already way less than the motor can take/provide, and the engine running gives the extra, with power from DCDC to give the motor extra umph, it would also be interesting to see how much the traction motor supplements to ICE on 25MY.

I've not watched Trailer drive mode to see it, but guessing it's similar to Sport mode where the motor is providing much more torque constantly.

As with any time "new stuff" is introduced there are always the undesirable consequences. It sounded like they needed the beef for the AWD support. Sounds like they probably should have bumped up the battery size a bit as well. Devil is always in the details.

Can confirm I’ve stayed in all electric 4-5 little bars high which is more than a 10% throttle input. Again not always long but I have.

I’ve never as much even rode in a Mav with the HF45 but I’m curious if there’s a noticeable difference with the increased power and gear ratio.

Who is around SF Bay area; has a 2025 Hybrid, and wants to borrow a ScanGauge III?

Now I heard the OBDII CAN protocol may have changed in 2025. But the ScanGaugeIII is pretty new too so may be able to scan it.
