As a prospective buyer of the new Ford Maverick hybrid truck I've been trying to educate myself about the hybrid powertrain. This video has been the most helpful I've seen with regard to shedding light on the eCVT. Thanks for the detailed explanation. Should be required viewing for anyone considering a Ford Hybrid.
Ditto Jim, I have the same comments as you for the professor. I would like to know as much as I can about the eCVT transaxle used in the 2022 Maverick. 👍
Being the same engine size, I'm sure they've mainly fine tuned & corrected flaws since this early version. My 2011 Escape hybrid has now crossed 180K miles & has had perfect reliability during my 115K ownership.
@@jeffdee5 .. same here.. Great information so far on how eCVT transmissions work..
@@dennisporter753 Now that I know it is Aisin built you should have a damn good truck on your hands. Hopefully the new motor will have no issues as well since it will be NA Atkinson cycle as well (low stress vs the garbage turbo motors)
I hear you. And I'm liking this hybrid stuff. Guess I've been in a cave. Good to know there's 15 years of history on this design. I really liking the maverick.
Enormous amount of prep. Everything is very clean and labeled as required for teaching. Professor Kelly, like all great teachers, makes everything so "simple."
Fantastic instructor and really appreciate the video😅
I love this guy's videos. He's a school professor and I have no doubt his students love him.
John is Awesome! 35 years as a A&P i have to know how everything works. John has an amazing ability to simplify anything, to a level anyone can understand.
The most Perfect presentation. I feel like i am learning in Engineering class. Thank you professor.
The first-gen Ford hybrids did have an EV mode, but (at least on mine) didn't have an EV mode selection switch, so you couldn't just pop it into EV mode and keep it there. You could only engage EV mode through a combination of low speed (
Thank you for making this! I have a 2013 C-Max Hybrid, and in the entire time I've owned it I've never been able to find anything showing the actual internals of the transmission, just diagrams describing it's operation (which also severely misrepresented the internal layout, for example showing the traction motor being directly inline with the output shaft, when it isn't). This was immensely helpful, I'm looking forward to the Voltec teardown. :)
Keep up the good work!
Thank you very much! I am glad it was helpful.
How has your transmission held up?
@@RobertBeedle So far so good! I've read that some of the early C-Max & Fusion Hybrid transmissions have an issue where the bearing for the main transfer gear wears out prematurely due to inadequate quality control, but I haven't had any of the symptoms of that yet, and probably won't (IIRC it usually occurred in taxis and other heavily urban driven cars at >100k miles, and that's not the type of driving I do, nor am I at that kind of mileage yet).
@@cyrenecai I hadn’t seen your response tell now. Glad it is holding strong! Sound like you can drive it for a long while yet. I recommend looking at the Ford Maverick Hybrid down the road. Ford is really killing it lately with their new options.
I am considering buying a 2013 C-Max Hybrid with 100k miles on the clock. The transmission issues have me a little bit worried. Any advice/insights?
Professor Kelly, thank you so much for all these videos! They help a lot a guy with manuals background to enter the hybrid world. I wish I have an opportunity to meet you in the near future.
Thank you very much!
Thank you. Your explanations for hybrid trans-axles helps very much and keeps auto enthusiasts up to date with manufacturers mechanical and mechanical operations innovations and development technology.
Thank you!
Thanks, Professor. Just bought a 2019 Ford Fusion Energi plug-in hybrid and it's interesting to see how this works. I'm fascinated by how few parts are involved. My unit is like the third generation unit you show in external appearance (outboard inverter/converter housing).
Great stuff.
Thank you very much
Thank you so much for making this videos they helped me alot with the ASE test A2 and A3
Thank you!
Thanks for the aeesome detail. You're student's are so lucky to have such an expert, who can really break this down in a such clear and a comprehensive way. Thank you for what you do!!!
Thank you very much!
Another great video from Weber Auto. Thanks for putting this together and sharing it.
Thank you!
Great vid thanks for posting love learning via your lectures...
John, y'all's videos are fantastic! Thanks!
Thank you!
Excellent presentation and well produced video. Your students are lucky to have such resources.
Thank you!
Very cool. Thanks for explaining these hybrid drives!
Thank you!
I've seen the name Aisin before as the mfr of the automatic transmission on the XJ Jeep Cherokee but never heard aloud... I'm going to consider your pronunciation the authority on this matter. Great videos!
Another fantastic and informative video. Thank you very much.
Thank you!
Thank you always interesting informative presentation. I feel your positive approach to teaching learning can be applied to all parts of our lives .
thank you for explaining this in detail
I love those videos, i studying auto-mechanics and these videos are very informative, Thank you!
Thank you!
Very informative! Thanks John for the presentation.
Thank you!
Wonderfully informative video. Thanks a lot, Professor!
Thank you!
Your presentations are really awesome thanks!
Thank you!
You the best thanks for this hard work and show us this hybrid system
I love this video. Thanks for your knowledge. We picked up a 2008 Ford escape hybrid a few months ago and I wondered how this technology worked. Usually when the car has run for a little while and charge the battery, then when I get to lower speeds and to a stop, the engine shuts off and I can run on EV mode from about 20 mph to 26 or even 28 mph if I'm gentle on the pedal. The electric motor also assists the gas motor while driving and at other times it charges the battery.
As always, very informative and clear video. I'm still impressed of how these gearboxs seem to be well built.
Thank you!
Great video and layout. Thanks for posting.
Thank you!
Phenomenal. I knew this channel would have this video.
Very simple and clear explication
Thanks a lot, sir! I always enjoy your videos and the level of your explanation! Keep it up! :)
Thank you!
Great presentation. Thank you so much. congratulation.
Thanks for this it help us techs understand operation better
You are welcome!
Highly informative; I was looking for the HF35 transaxle online and found nothing; the Toyota HSD powertrains have much more info online than Ford's versions.
Backtracking a year ago I remembered asking you about the EV operation of the Prius P410 vs. the Fusion HF35 in regards to EV operation speed range. Watching this now, seeing how high the ratio is between the Traction motor (or MG2 in Toyota-speak) of the HF35 is over the P410 gives me the impression the Ford motors are capable of much higher rpms & without the limiting factor of over speeding the smaller Generator/starter (MG1) unit.
I also find it ever so humorous the P610 actually took Toyota (often regarded as the leader in hybrids) to take a page out from Ford's playbook for the Prius IV. Even more interesting is how the upcoming Prius Prime with probably a similar transaxle setup will put in the one-way clutch on the engine to allow for dual MG1+MG2 combined EV operation similar to the Volt's 4ET50 but using this PSD setup. That would be a cool video in the future.
As an historical fact, Ford and Toyota share many of the hybrid ideas and patents, since Ford saw that most of its ideas were similar to Toyota patents when the Escape Hybrid was under design. They are still sharing ideas.
Very interesting. Never really knew how it all worked even though I️ work in a shop manufacturing most of the hf-35 gears shown.
Thank you! Thanks for the feedback!
perfectly explained. thank you
Thank you!
All these videos have been amazing, Prof Kelly. While I don’t have “too much” difficulty understanding the gears, sprague clutches, dual motor/generators, the “magic” that’s beyond me is the HOW of the inverter-converters.
Hmmmm. . . the gears of the Toyota units are cut opposite to the Ford units. , .
Thanks for these videos, like you said at the end it is nearly impossible to find information on the Ford hybrid transmissions compared to the Toyota designs
Thank you very much!
These transmissions work great I have a 2014 fusion hybrid, I’ve had it since it was new and it’s got 238k on it and the only problems I’ve had is it needs shocks in the rear about ever 100k because of all the extra battery weight and crappy roads, and the secondary door for the fuel fill gets stuck open and doesn’t seal from time to time and causes a evap leak but just lube it up and poke it a bit with a stick problem solved. But it’s been great the first time I did brakes was at about 150k and it still didn’t need them quite yet and the only other week points are the bolts that hold the electric motor on the steering rack corrode and brake so replace them every few years there easy to get to, and ford did recall them but they’ll only do it once and there fix doesn’t last forever. There are a few things on the interior that have broken along with some creeks and squeaks but overall been a great car, I’ve got access to trucks suvs sports cars commercial trucks and motorcycles and the majority of the time the fusion is the go to, it just gets the job done and has never left anyone stranded.
Thank you for these super informative videos. Wish italian professors could be as professional as you.
For the P610/Prius IV transaxle operation: from regular users with an OBD app, it looks like the logic is the same as Gen3 Prius/P410/P510. Ratios are different, it stays in EV at much higher speeds(100+kmh/60+mph), but the stages are the same
Thank you! You are correct, it looks like the same logic.
Hello John and thank you for the very extensive video. At about 5:50 you said, 'This 1st generation hybrid Escape did not have an electric vehicle mode; the engine always had to be running, except for idle stop...' Please note that the 1st generation FEH (Ford Escape Hybrid) does have EV mode, though there isn't an EV mode button as in a Prius. In EV the 1st gen FEH can accelerate (engine remaining off) and can drive in EV mode. I believe I've read that the 1st gen FEH limit for EV is 40mph. My wife and I own a 2006 Escape Hybrid and on many occasions I've accelerated/driven over 30mph in EV. Hope this helps. [Edit: typo]
This would be normal hybrid operation. For city driving it is possible to operate exclusively on the electric motors provided that you don't reach the speed at which the gas engine is started. In a true EV mode however, the gas engine is never started during normal driving - dead battery and 85+ mph is not considered normal driving.
You need to get in a vehicle that has an actual EV mode selection and learn the difference between hybrid and EV. I sense that you believe "other" hybrids (without EV mode) run the ICE all the time or whenever the wheels rotate.
You say "true EV mode" is where "the gas engine is never started during normal driving" but that is not how hybrid vehicles like the Ford Escape Hybrid and the Prius function. Such hybrids have specific parameters programmed that dictate when the vehicle can run in EV mode and when the ICE (internal combustion engine) runs. One example is that when driving in EV mode the battery will be discharging and in our 2006 Escape Hybrid when the battery SoC (State of Charge) drops to 40%, the ICE comes on to charge the battery regardless of how slowly one is driving. I have no idea what you're referring to about a dead battery or 85+ mph.
Also whenever the AC compressor is required, as it is belt driven in these early models (1st gen Prius, too).
Wonderful video! The first gen escape did have full EV mode. They actually drove quite a bit in EV around town. Now they did have an accessories belt type AC compressor so if you turn it to max AC the engine will not shut down since it's running the compressor.
That is very true. Newer hybrid Ford models use an electric A/C compressor powered by the same battery as the electric motor. Look in any new Ford hybrid engine bay and you see a small pair of orange cables going to the compressor which by its vestigial design is still attached to the engine block side as it was belt driven.Yet the gasoline engine has no belts or pulleys since all the powered accessories are electric.
Correct and more details are that the battery needed to be over 40% SOC and the engine water temp over 160F for EV mode and speed limited to ~30 mph depending on incline and acceleration. About 2-3 mile range.
Prius didn't get an electric compressor until 3rd gen so this checks out!
@@Trammael no the Prius got an electric compressor starting in the Gen2 2004 model year. I know, I’ve replaced one myself on a 2005.
Thanks, I have a 2015 C-Max Hybrid and have not been able to find this quality of demonstration of how the transmission works.
Thank you! I am glad it was helpful
Hi John as someone commented that you didn’t comment on the low gear position of the selector on the Fusion. Prius calls it B for breaking I think that break pad to stop the generator motor may be activated by that selector position because the engine then is used to slow the vehicle down and no it’s not low gear ratio but the engine revs quite fast but is just used to drag the vehicle speed down. And on downhill assist when the batteries are fully charged on a long downhill the Fusion uses the engine to supply drag to prevent the car from speeding up on a steep hill. This is because it cannot use regenerative braking when the batteries are full charged. Anyway that’s my thoughts on the matter. Good show John I really learn lots from you, thanks very much!
Thanks for your feedback. The engine is used to provide drag, but not a running engine, but an engine that if off (no fuel supplied) and being rotated with the small motor to dissipate the extra energy created during deceleration.
Nice informative video John!
Thank you!
Yes, a very educational video. Thank you for taking the time to put this together for us.
@@WeberAuto John, I might have missed this in your video, could you help me out? For the 3rd gen Ford trans, what is the number of teeth on the final drive (not final drive ratio) and also the teeth number of the top gear of the "transfer gears" that connects to the final drive. Thank you!
Thanks for taking the time to explain these. Does the ICE ever become direct drive with the drivetrain?
Thanks, you're too cool! Happy new year.
Thank you!
Outstanding video! Thank you for the education. I’m going to check out the rest of the channel. Do you have a video on how the Ford hybrid engages / disengages the drive axle to the wheels? I have a 2022 Ford Escape hybrid that at times bangs when switching into drive and then is very loud moving forward… almost like something is not fully engaged or fully synchronized.
fantastic presentation,
Thank you!
always top quality, thank you ...
Thank you!
great video I think on the 3rd gen you meant to say that it had an open differential not an open planetary. always enjoy your videos. they are very well thought out
Oops, yes, I meant open differential. Thanks for the feedback and kind words!
Thanks for amazing videos. your explanation and a way you taking videos are so helpful. you mentioned that traction motor size is 88kW. so I wonder what size is generator motor. May I ask you the 3rd gen of ford hybrid's generator motor size?
I have been considering a Ford Fusion plug in hybrid because of the easily serviceable big battery and really appreciate knowing how it all works. I was pleasantly surprised that the system does not have the "belt" even though it is called a CVT.
Lots of great information and it was presented so well, I could understand pretty much how it all works without even being mechanically inclined myself! Question, though, do you know if the 2016 RAV4 Hybrid is based on the P610 or is it more closely related to Toyota's third generation hybrid transaxle? It'd be neat to see a tear down of the rear transaxle (MGR) as well on the RAV4 hybrid to see how that works compared to the front transaxle with the ICE, MG1, and MG2 drive setup. Keep up the great work! I've learned way more about how hybrid transaxles work watching your videos than anywhere else I've found in my researched so far! We bought the 2016 RAV4 Hybrid a month ago and really enjoy driving it. It's neat knowing exactly what's going on under the hood when I'm watching the power monitor.
Thank you! the RAV4 Hybrid uses the P314 transaxle, just like the 2013 and newer Avalon hybrids and Camry hybrids. It is more like the 3rd generation transaxles. I have an MGR and will be doing a video on it's operation in the next month. Thanks for the feedback!
great video. enjoyed watching it. I admire the the toyota/aisin hybrid design.
It's primarily the Aisin design.
Aisin approached Toyota in the 90's and they weren't interested. They then approached other manufacturers and it was Ford that first partnered with them, even though it was Toyota that got their vehicle to market first.
Professor kelly
Thank you for this presentation
I want to ask that its correct that the 3rd generation HF35 have alot of problems and have a failure history?
If yes how we can prevent the tras. From failure??
Excellent stuff. I wish more people would know about how these systems work and not go on endlessly about rubber band cvts
Thank you!
Thank you professor for your work and your precise explanation. One question, on the Ford HF35, does the oil pump always turn and lubricate even with the heat engine off or does the oil need a heat engine to turn that also turns passively downhill? Thank's for your job
Great job👍
Thanks, Good Stuff I love this stuff.
Thank you!
Excellent sir
Thank you for the videos, great work really professional. Do these Ford E-CVT's use a push belt?
Not Ford
Great in-depth video. Can you tell me what is going on inside when the Maverick is being towed?
As always, great presentation, very well explained. Thank you for sharing. Looking forward to the Chevy Volt transmission video.
Since all three transmissions look fairly similar, I wonder if Ford had to pay royalties for "borrowing" Aisin's design, even though their HF-35 is slightly different ?
Thank you! I do not know about the licensing. Thanks for the feedback!
I have an 06 Escape. At 10 years, we burned out the transaxle, in concert with another transmission issue..I found a transmission specialist, who replaced with a junkyard transaxle, works great, eight years now. About 20% of the cost
John thank you for your informative video. I was in the carhaul business when these came out and Ford was one of our customers. when ever a new model comes out the mfg. sends out bulletins to the carriers how to haul them as to tie down ,trans , position etc. Ford said these would be shipped with the electric sid disconnected ,only the gas engine would be used. First problem, there is no reverse without the electrics turned on and so if you drive one on the transport you have to back it off. If you back it on the transport you drive it off. for some reason the only way the vehicle will go in reverse is the electric traction motor has to turn backwards. Toyota had the same issues . Now I know why. they were the same. thanks again.
That is awesome! Thanks for the feedback!
Watching the video, I was wondering if reverse was electric-only - thanks for clearing that up!
Thank you very much.
Thank you!
Thank you Professor, very much, for really nice presentation. Please can you make presentation for P710. I believe that one moves new Corolla 2.0 hybrid. Is p610 in Corolla 1.8?
These videos are a fantastic resource. The Ford HD10 could run without spinning the ICE up to road speeds of approximately 40 MPH. However, I was only able to achieve this when traveling downhill as it seems the electric motors didn't have enough torque at those speeds to keep the vehicle accelerating. Ford often quoted a top EV mode speed of "25 MPH" which is probably due to the limited torque available.
Thanks for your feedback. I got that part wrong.
That sounds very Prius-like, anecdotally the gen-3 Prius will usually start the ICE around 43mph regardless of torque needs, maybe up to 45 under some conditions I haven't narrowed down. I presume that's the MG2 overspeed limit.
Hello Professor Kelly would this transaxle be the same or similar to the latest Ford Escape Hybrid ? .... thanks for posting these wonderfully interesting videos.
Thanks for the suggestion. I am looking for one.
Outstanding video Professor John. I have just bought a 2014 Lincoln MKZ 2.0L FWD Hybrid with The Hf-35 xCVT trans and it is leaking out about 3qt, but the car drives great. Because of the leak the Transfer-shaft assembly (EG9Z-7H348-A) bearing and cup should be shot, but those parts only cost US $410 right now. Is it possible to put a rebuilt used HF35 eCVT or even a newer Ford 2017-up HF45 eCVT and not have to reprogram the power transfer unit? The only cable that comes out of both trans are the hi-voltage drive/regen motors and the low-voltage data cables (that reads both motors temp and speeds). From what I have read; the HF35 has no brain or need for VIN programming itself. I ask because my locale Lincoln Dealer just quoted me US $10,000+ to replace the HF35, recalibrate the Lane-departure system, and realign the wheels. Since I was not born yesterday and value my family's treasure, I figured I would ask an expert. The car is beautiful and still drives it just need seals and bearings but no trans shop in or near Chicago will touch these eCVTs due to Ford's EV service equipment requirments (an anti-static bay). I have removed FWD trans and replace clutches before and I am thinking of removing and rebuilding my own trans because of inflated dealer costs. Any help you can provide would be much appreciated "for eductional info only... lol". Thank you for your time, sir.
BTW: Can you do a trans removal video on the HF35 and HF45? That would be amazing.
Thank you
Thank you!
An excellent presentation professor. I have a 2nd generation in a 2011 Lincoln MKZ. I've read in the Fusion forum that there have been some issue's or failures with the 3rd generation. Would you have any insight on that? Thanks, Don
Thank you. There were some bearing failures, but that has been addressed by Ford.
Gracias muy buen maestro
Thank you!
Time for a new hybrid transaxle with 17000 RPM PMSRM motors.
Why are those boost converters being used? Is it to use lower current switching devices?
Question on the ECVT in a 2008 mariner. The shifter has a D and L range that doesnt seem to do much of anything. Does the eCTV actually have a low range?
I got the answer I was looking for. The Prius and the C-Max transaxle are very similar if not the same
Is there a need to change oil in FORD or Toyota Ecvt bezstopniowa skrzynia biegów Transaxle ?
Thanks John. Will you get a P610 to pull apart? The 2016 Prius is a small unit as well. I'm told they've used different materials to downsize. Something carbide I think! I'm a long time subscriber and I've learnt a great deal from you, better info than factory training here in the U.K. I thank you again.
Thank you! I hope to get a P610, but my sources are from salvage yards. I need someone to wreck their car first. I am not aware of any special materials in the P610 (compared to previous models). I believe the downsizing comes from the parallel axis motors. Thanks for your feedback!
Sorry John, I missed a word! I meant the inverter is downsized. It is a lot smaller and sits a little lower in the engine bay too. They had a transaxle on a stand on the model training but not one to strip! If I could fit it in my pocket I'd mail it to you!
I like u guys !! and thank you so much!
Thank you!
I’m looking at electric transaxle options for a VW dune buggy conversion. The tried and true method is to bolt something like a Curtis AC-50 motor to the existing transmission but those motors are pretty expensive. Some things I’m unsure of with these more modern ev transaxles is how well they would run at lower battery voltage if they were from high voltage systems, if some are designed for more attainable battery voltage of 150-200 volts, and I’m confused by the hp ratings of the motors. I’ve seen the small rear electric transaxle for the Prius rated at 6hp but I’m unsure if that is electric hp or gas hp. The dune buggy I’m looking to build would be primarily used to get around the farm so range and top speed isn’t really an issue. I’d like something with good low end torque. I’d appreciate any advice.
@WeberAuto Do you have a plug in hybrid escape 22 transaxle? I know tow rating says 1500 pounds but I got class 2 hitch from factory and odds are all my stuff for possible move will fit in a 6 by 12 uhaul that weighs 2k pounds. Wondering hw trans would hold up.
I need the bearing on the end of the generator/starter motor for a 2014 Cmax Energi. Do you have a part number or bearing number?
great video professor ^_^
do you know any one where i can order a transfer gear ?
it seem s like no one has them ... :(
if you can please point me to right direction I would really appreciate it
I have a 2022 escape phev that I am looking to tow with. I am finding conflicting towing ratings between Ford escape phev(1500) lbs and Ford Kuga phev (3300)lbs. I do believe the Escape rating is considered unbraked and the Kuga rating is considered braked. The vehicles are the same as far as I can tell with the drivetrain. What would be the towing limiting factor in your opinion? Stator cooling? The owners manual also states not to tow in EV mode. Again the only factor I can think of is electric oil pump vs engine driven for cooling. Appreciate all of your videos, I'm learning a lot.
great video. I have a 2005 Ford Escape hybrid, good to know how the ecvt works. Thank you
Still running reliably?
Thanks
How does the engine start when the vehicle is rolling?
Professor: i have a quick question IF this is Basically a Gear transmission, meaning it does not have solenoids, why cant it uses thicker oil than mercon V in Ford escapes hybrids? my transmission whines a little and i wonder if i can put an oil additive like Motorkote MK-HL32-06, to help with the lubrication but i wonder if it would create any issue, i have used it in a manual transmission that was whining a lot, and worked like a charm please let me know thanks
Many thanks for this presentation. I've found a couple of interesting facts on the HF35 in the Energi plugin cars. The traction motor has an 88kW rating, but the 7.5kWh traction battery has a 200A discharge limit, so only about 60kW is available in EV mode.
Also, if accelerating from a stop at WOT in charge depletion hybrid mode, the traction motor's power ramps up very slowly, not reaching its full 60kW output until nearly 60mph. I can't think of a good reason they would limit that traction motor output at lower speeds with the engine running, unless they are trying to limit torque on the differential or axle shafts. Too bad, it could have been pretty quick.
Thanks for your feedback, great information! I wish I knew the answer myself. Finding information on this transaxle is almost impossible.
They also needed to make sure it was slower than the 2.0 ecoboost
From official Ford literature (of what little there is) for the 2017~ the HF35 in the Energi cars are limited to a maximum discharge of 68 kW of power in EV mode. So the Traction motor 88 kW cannot be deployed unless the 2.0L engine is on and supplying power via the Starter Generator (e.g. MG1). Not sure if the earlier 2013-2016 cars had the same output however.
Please !!!! What procedimento from check level transmission HF 35???
Thanks!!
Another stupendous video! Thanks!
P.S. Straighten out your collar. LOL :-)
Thanks, I noticed that after filming. LOL
Gracias ❤
Professor Kelly, I call numerous transmition shops to see about a fluid change for my 2014 ford c max energi. Service guy at ford said I just needed coolant change. And not transmition fluid change as it was an electric transmition. I really think they are wrong. Because gears and motors need lubrication. Need advice thanks
Thanks for the video. One thing I'm not sure about is how the gear ratio between the engine and final drive is altered. Is this done by controlling the speed of the starter/generator by controlling current draw?
Yes, there are two torque paths, one from the engine/generator combination, the other from the traction motor. The difference between engine rpm and generator rpm determines how much assist is offered to the traction motor to drive the final drive.
The ICE does not have to be on to have electric function. When the 2005-08 enter full hybrid mode it can run off battery alone (no ICE running) at speeds up to 65 km/hr for approx 2 kms. That speed limit is to protect the eCVT.
Still having trouble understanding ecvt mode. In pure electric mode traction motor turns the ring gear from 0 to 60 mph, one gear, right? In pure ice mode, engine connected to planetary gear and generator connected to sun gear. How does car change gears for ice operations? How does the ecvt change in going from 0 to 60 mph, in this case?
Where is the output transmission speed sensor located on a 2016 Ford Fusion Energi? I never see any videos on this here on UA-cam anywhere.Does it even have one?
Good afternoon. does the Ford C-MAX hybrid gearbox have a variator or is it usually an automatic? a robot ?
