2025 Maverick Hybrid HF55 Transaxle Info (nice write up)

[Phimosis]

Spent and hour with the Maverick product manager that’s straight from the horse’s mouth.

Additionally HF55 already paired to 2.0eb in nautilus.

HF55 new and improved putting down much bigger electric power numbers resulting in faster 0-60 and highway passing acceleration while supporting AWD and 4K and maintaining the same efficiency as the FWD HF45. Super impressive!!

HF55 putting down faster acceleration and faster passing numbers with the same 2.5 N/A input HP is directly related to having a larger KW generating capacity of MG2, which lets it apply more drag on the ring gear of the planetary gear set, to change to higher gear ratios faster, keeping the 2.5 engine at full throttle without running into the rpm redline.

All this improvement talk has people in awe, yet less than 10% will ever utilize its capabilities to it's full extent.

Increase battery size, or make a PHEV then we have something to rave about and have something to compete with sliced bread.

Not needed for me.

PA has no fee for a hybrid, but they do for any plug in.

I don't want to EVER plug a vehicle in, why go halfway, buy a hybrid or an E car.

Why hassle with 20 minute charges ever?

Further, put a little more time in my 25 today, in a bit of a hurry, this truck is quicker and faster than my 24.

Dyno?

No, but my gut feelings are good.

 

[HeyBales]

When someone actually Dynos one well will have real numbers. The 2022 dynoed 267TQ if I remember correctly. Ford never published a number anywhere near that.

True.
But in the system settings they do have a reference Torque which is higher than both, so likely the combined, that other PID's that display % of torque use. Possibly other calculations use the reference too.
So it may be their best steady state they can count on for combined. Kind of like the 191 HP.

I was looking for a screen shot of Forscan Lite showing the 245.6 value, but I didn't have one.

When you look at the HF55 in the Nautilus, it adds 50HP beyond the 2.0 Turbo HP. If the same electric motors and trans add 50 HP to the Maverick's 162 engine HP, potentially raising it to 212HP in The Maverick Hybrid seems to make sense.

So it sounds like you and @DevoMcDev0 both agree that the 25 Hybrid is quicker then the previous MY Maverick hybrids were correct? I'm still looking around at Mavs but am really close to making the jump soon. The AWD Hybrids are really tough to get near me but I have a beat on a couple of them. I hadn't ever driven a Maverick hybrid until a few days ago and was only able to drive a '22 with like 58K on the clock. I was really impressed with how smooth it was and it drove pretty much the same as my wife's 23 Escape Hybrid. Glad to hear that the '25's are even better

To be clear.

I LOVED my 24, had it undercoating, bedliner, it was supposed to be half small work truck, half daily driver.

My helper, who I planned to keep working with until I was 61 1/2, got an early disability at 61.

He deserved it, brick/block layer by trade and truly disabled.

I wasn't training another worker, so, I retired early as well.

So practical Mav, of perhaps another 2 to 3 years became my new retirement truck.

I ordered a 23, got 2500 off my 24, so, I sold it on Carvana, for more than cost, and put 4K towards a hybrid AWD 2025.

Likely a one time deal due to Covid and supply constraints, timing and luck, also got Employee pricing on the day I picked it up saving another 850.

Truly a gift horse.

Now I like specs, if you work with equipment torque, HP, amps, volts all mean something.

My 25 is the result of years of studying Mavericks before buying one.

YES!.......

I regret not buying one on day one, specifically a hybrid, but history has taught, year one models, stay away from them.

The constant improvement by Ford, in this case is encouraging, I thought the 25 was strictly a face lift, but it's not just a driveshaft added, but upgrades to be better than just an HP drop for adding that axle.

Improvements for towing, which I care nothing of, are a bonus, and value added to my 4K upgrade cost.

 

[The Real Maverick]

Here’s the crux of the issue:

You provided a lot of drawings and animations. I'm sure many will appreciate those. But let me clarify a few points and help you get it right for next time you want to help someone.

MG1 is a Toyota term. Not a Ford term.
MG1 equivalency in a Ford is the Generator/Starter motor and is usually, in the first four generations, the smaller of two.

The smaller "Generator / Starter" is connected to the sun gear.

MG2 is a Toyota term. Not a Ford term.
MG2 equivalency in a Ford is the Traction Motor and in the first four generations of eCVT is the larger of the two.

(There is debate / confusion in this thread about which is largest in the 2025 fifth generation eCVT.)

The larger Traction Motor is connected to the ring gear. The larger traction motor provides regen braking / battery recharging, as well as EV mode propulsion.

The gasoline engine is connected to the planet carrier.

The wheels / output shaft are directly linked to the ring gear. The physical arrangement is: Traction motor to final drive (wheels) then final drive (wheels) to transfer gear, transfer gear to ring gear. As in the top drawing, the traction motor is physically outside of the planetary gearset, but meshes with the planetary ring gear after passing through the output shaft gear and transfer gear first.

The output gear / shaft is not shown in any of the pictures above. But is below.

Anytime the wheels are moving, the ring gear and traction motor are moving. The traction motor spins roughy 10 revolutions per wheel revolution. And the generator/starter spins an equal speed in the opposite direction when the engine is off. As the engine starts and speeds up, the generator slows down (gets less negative rpm). If the wheels are stationary, then the generator must spin if the engine is spinning and this will be a fixed ratio. The generator may recharge the battery, or it may freewheel. Just like when coasting down a hill, the traction motor may generate to recharge the battery, or it may freewheel.

The smaller generator / starter does not regen brake, which may be counter intuitive to some.

Of worthy note: the oil pump is connected to the planet carrier, thus fresh transmission oil is only circulated while the gasoline engine is running. Which is likely the reason you'll need to start the gas engine every 5-6 hours while flat towing. There is no disconnect of the gears while neutral flat towing. Just the power in and out of the transmission is disconnected.

FLOW:

Yellow is Traction motor (MG2)

Red is final drive / to & from wheels

Blue is a transfer gear

Purple is Planetary Gearset (outside of ring connects to blue gear, not directly to traction motor, but gets to the traction motor eventually).

Green is Generator / Starter Motor (MG1)

Engine comes in from below the table and connects to the planet carrier. (Not visible)

So not quite like the animations, but close.

Lmao what sort of proof do you want? It is absolutely unhinged to read this completely innocuous interview and choose to not believe it

Reporters confuse kW and HP and MG1 and MG2 all the time. Because they don't understand it and don't really care.

50/50 chance it was recorded, or remembered, and regurgitated correctly.

Not only are the 25's quicker, but give better mpg too. Instant power off a stop. New gearing is helping them off stops for sure. I don't see any drawbacks to the 25's. (I'm ok with the touchscreen bottom buttons and voice controls, and feel that the front end looks more upscale) The headlights are the bulls horns.

Also the 2025 rides better, doesn't seem to do all those annoying module clicks at shutdown. Has a way better backup camera, and just feels over all like the refined the quirks and bugs out of it. Yes it was more expensive, but this is the one I want to keep.

the sticker on my 2023 Tremor XLT+Lux (moonroof, no CP360) was $34,300

Sticker on my 2025 Lariat AWD Hybrid was $40,280.

The difference I paid between the two was even less, around $4,700. For that amount the 2025 improvements are well well worth it to me and I agree with everything you’ve said.

My 25 was $7,000 more sticker over my 23. $2,750 of that was additional options, and I got $2,450 off between the employee pricing and the $750 rebate. That brings all the upgrades the 25 brings to $1,800. Considering cars increase about $1,000 per year, I am very happy with the price paid. To order a new 2025 now without any discounts, would be about $4,300 more than I paid. That would be salty. Over $34k for an XL hybrid with AWD, 4K, CP360 AND SIBL. Sounds crazy. Now is the time to buy. I got mine for under $30k.

I appreciate the reply and the info and enjoy that early retirement.

Thanks for the reply back and all the good information. I found an incoming XLT Maverick that my dealership has put on hold for me so I'm going to check it out when it comes in. It's a 25 AWD XLT Hybrid and will be a change going from my Mustang but it just seems like it's time to get in a more practical vehicle here in MI.

I know you went from a 23 Hybrid to a 25 Hybrid so I have a few questions for you. Did you do anything about covering the hole in the wheel wells on the one side in your 23 or your 25? This is what I'm referring to:

https://www.mavericktruckclub.com/f...body-cavity-shield-covers-just-arrived.59568/

Also since you've had a 23 and now a 25 I'm wondering if you can comment on the whine or siren noise owners of the 25's are noticing that appears to be something different than the previous years hybrids. Some are saying maybe it has to do with the new HF55 system? Here is a thread for reference:

https://www.mavericktruckclub.com/forum/threads/25-maverick-hybrid-wine-when-ice-comes-on.66441/

Last but not least I'm curious if you had any of the 12v battery deep sleep issues with your 23 or if you've see any of those issues with your 25? I know the 25's should have an AGM battery in it but it sounds like some 25 owners have had deep sleep issues already so this appears to be either a software or hardware issue that hopefully Ford will be fixing.

My wife has a 23 Escape Hybrid AWD for two years now and we've been through a few 12v batteries on it but it's a great vehicle overall and it does really well in the winter here in MI. I briefly drove a used 22 Maverick Hybrid earlier this week and it drove pretty much the same as my wife's Escape and I really liked it. I'm going to try and drive a 25 if I can find one before the one the dealer has on hold for me comes in. I want to see if I notice that whine or whistle I mentioned earlier on the 25 and just see how I like it overall compared to the 22 I drove. I think my dealer has a few 25 XL FWD's on the lot I can drive so it should be a close comparison (I hope, lol).

but.. then GPSMan would have the face the stark reality that a '25 hybrid, whether fwd or awd, was superior to the truck he's driving.

he's always had a strong reality distortion field. we're talking about the guy who's sure the hybrid gas tank capacity is actually the same as the ecoboost, it's just that Ford dramatically underrated it so that you don't ever run out.

The whine/siren happens when the ice engine kicks on and I believe begins powering the generator motor it is way less noticeable or intrusive than the ecoboost engine and it is a totally normal sound for electric motors.

I agree. The 25 hybrid to me feels more like a redesign since there have been so many changes and improvements (AWD, new stronger HF55 transmission, better battery charging system, better cooling, better gear ratio, more power, 4k tow package, no more grabby brakes at low speed or when wet and a lot less odd sounds and clicks when the vehicle is off). On top of all those big changes you have the new and I feel improved front end design and much better infotainment system. I was happy with my 22 xlt hybrid (even with all the odd things it did) but I'm loving my 25 much more.
