- Taking my EV Humvee off-road because AMERICA! Bring some Hot and Savory Healthiness to your own life with Huel: my.huel.com/apriljerryrig and Huge thanks to Huel for sponsoring this video. This Electric Hummer Conversion project has been CRAZY. Putting 95 kWh worth of Tesla Battery Packs into a military HMMWV is not an easy task. Today we find out how much rang JerryRig's hummer has - as well as what the Hummer EV is capable of off road. Join us! Would you buckle up next to me?!

A pleasure to help!
The EV Master has arrived.
Gotta do a LMTV next!
Really enjoyed your videos
I've got an idea: Find a Ford Excursion with broken engine, and turn that into an EV.
@@JerryRigEverything you're awesome bro
Off road projects are just that..........projects, they are never done. You can always find something to break or upgrade. Love seeing the journey and have learned a lot myself.
You definitely need a lot more suspension travel. But good to see it driving.
🔥🔥
Yes it was like driving a House Brick.
HMMWV/H1's don't need as much suspension travel as other vehicles since they are so wide and a low centre of gravity design they are very stable they just tip with the terrain..
@@Injunfarianexactly. This comment is accurate. I own an humvee.
@@lt9690Yeah I own a H1 and have put that thing on some pretty gnarly angles...
2 years! Dude I didn't realise I've been following this project for that long. What a success to finally get it out and up that hill. Very impressed bro
You should totally paint a Helipad on top of the metal plate where the turret was. Have a nice landing spot for your drones.
Exactly my thought! :)
That's where the solar panels are going to be mounted. He could make a frame that snaps into place, over the panels. Maybe out of some clear acrylic, with a circle and a big H graphic.
hahah i just left the same comment, or a D for Drone Pad ;)
He calls this a mountain? Pathetic.
Jerry, do some research on Torsen differentials in the hmmwv. There is a method of using the brake to lock them up while ur on an obstacle. Once you master that this thing will be unstoppable.
And lower your tire pressure. Going down to about 10psi will make it ride 5x softer and give you loads more traction. I’ve been following this project from the beginning and am both sad and happy to see it finished. Great job 👍
This needs to be higher !
Great tip!
I was going to say the same, Learned this Torsen trick back in the military.
For those that don't know. Torsen differentials won't lock up if there is 0 torque in a wheel (when 1 wheel lifts off the ground). By applying the brake, this creates torque in the suspended wheel which lets the diff lock up and spin the tire with traction still.
I totally forgot about the tire pressures though - great tip. That will definitely improve traction and ride. I still think he would need to adjust the spring rates a bit though in conjunction with this. Even when the truck landed down on the tires (which appear to be fully inflated), you could see very little articulation in the suspension. The lower tire pressure will help compensate, but he still needs the articulation on impact.
Lower pressure is fine (ATVs/quads use about 4 psi) as long as you're not cruising down the highway. At speed, it can result in a lot of friction in the rubber and heat the tire to the point of failure. So bring an air pump.
i came here to comment the same stuff
So cool to see the progress over these many months. Amazing to see it power through the climb. Congrats on making this milehill/milestone!
Congratulations! It's crazy how long these projects can take when you're doing it yourself and learning along the way.
Hey. Where is the second Jerry? I saw him go out with you last time with that portable cooler in the mountains. I hope he is fine🫣
I left him behind. He's still on the mountain.
@@JerryRigEverything you're a rude person
@@JerryRigEverything Is he?😮
@@JerryRigEverything what a sad 😅😂
There is actually only one Jerry. Zack is the host of the show. It’s a common misconception I believe.🙂
I'm definitely interested in a cost breakdown.
Me too! I want to know how realistic this is... Seriously thinking about building an EV project.
Same, I always wanted an old military hummer or even a deuce and a half to make electric. Can you imagine making a deuce and a half with 3 or 4 motors and a couple tons of batteries to push that thing? Would be soo cool!
I hate this. Don’t comment it. No one asked you for your input.
Is about 10-15k$ for each part + labor.. The HMMWV, the Tesla pack, the drivetrain+charger and ancilleries. So around 60k$ if you count 15k$ in to labor.
There’s a whole ton of pride and fun in building something and making it go up some sketchy shit. Way more fun in building it, testing it, breaking it, fixing it, building it again, making it better along the way!
5:23 That is a lovely view of the snow-capped mountains, lake, and open fields. 🌞
I can’t believe Jerry made Zach do all this and didn’t even show up to help
I figured he made him stay at the base of the mtn!
Zack ditched Jerry at the end of the last video, so Jerry's probably grumpily walking home during this whole video.
@@mjc0961Jerry was his grandad right?
@@ttschannel875 lol.. 😂😂
I think he is his own grandpa
I can tell you from my experience in the Army, going over 50 in a humvee feels like you're doing re-entry on a spaceship. You'll want to do something for suspension for sure.
I highly doubt that - unless it's on some gravel road in the forest or out on some battle field. Of course it's probably a lot bumpier and noisier than a regular car, but on normal highways, it's still just 50 mph (which is about 80 km/h for us non Americans), in a car! It seems like he is simply not used to high speeds, haha. I also base this from one of the earlier videos of this project when he talked about the the "torque converter" (or that's probably wrong word - it's not the type used for ICEs, but like a single gear gearbox put between the motor shaft and drive shaft) and started to tell that "without it, the top speed would be like 125 mph and this car would probably fall apart at that speed".
That's in fact totally irrelevant to why it's needed. It's all about to get the right ratio between torque and rpm, to use the available power most efficiently. Without it and using the same motor, he would probably just get worse performance. He would get less acceleration, but the poor aerodynamics of that car would "suck" so much power at high speed, so he would probably not get much more usable top speed anyway (maximum current draw without overheating the batteries would probably be the limiting factor instead - and the range would drop to almost nothing).
So the 80 mph (129 km/h) he chosed, is probably quite optimal (given the limits of that type of vehicle) for fast drivers on normal roads. But, he could probably change it again to get a top speed of just 55 mph / 89 km/h (he isn't going faster anyway), then the motor would run more efficiently during the off road driving.
@@Speeder84XL 👀
@Speeder84XL As someone who's done drives from 29 Palms to Camp Pendleton and back (6+ hours of highway driving) as well as other drive on public roads/Highways in a HMMWV.
These vehicles were not meant to be driven that fast on those kinds of roads. Maybe it's the turbo diesel making it feel like hell, but I honestly doubt that.
If you really want to know, buy a surplus one for like $5000 and you'll see how heinous these things can be on roads/highways. Offloading though it does good.
@@Speeder84XL I'm not sure you know what suspension does. The humvee has some pretty heavy duty suspension and as Zach mentioned they removed the turret plus he removed some other components. So the vehicle is lighter with a very stiff suspension. This negatively affects performance. You can clearly see as he traverses the hill that the suspension doesn't articulate much, especially over the bumps. This negatively affects the handling (especially offroad) and the ride quality (poor Zach is going to rattle his brains out). The suspension needs to be adjusted, keeping the natural frequency and motion ratio ratio constant, combined with a lower sprung corner mass (due to cutting the weight of the turret plus any potential mass loss/weight distribution changes associated with changing to the E-drivetrain), this ends up reducing the required spring rate.
Because Zach said he has more work he wants to do (which will add some more weight again) he shouldn't adjust the suspension until he's done building the vehicle - as a final step - otherwise the suspension won't be tuned for the final weight/weight distribution of the vehicle and won't be optimal.
@@Budorb Yes, but then it's probably more a question about noise and vibration - of course, in that case, many drivers will go slow to make the ride more comfortable. Many parts in US also have quite bad roads with pot holes and bad pavements - that in combination with stiff suspension isn't the most comfortable.
What really got me here is when he said "I don't know the 0-60 time, because I have never gone more than 55 mph". That means he would never have hit 60 mph (97 km/h)
- not even for even a second. I get it, that car is not very comfortable at speed, but not even hit 97 km/h for one second, LOL!
Last summer I had a car without working AC, so during hot summer days I had to drive with windows down
- since I like speed and typically go at 160-200 km/h (99-124 mph) on the highway, the aerodynamic noise by the air current over the windows got ear damagingly loud - but I simply put earplugs on rather than have to chose between "cooking" in the car or crawl along at like 100-120 km/h to not get bothered by the noise. So earplugs also works if noise is the issue, haha
I can’t believe I’ve been keeping up with this series for two years 😧 totally worth it!!
Love it!!! What Could Possibly Go Wrong?!!
You have to drag the brakes to get them Torsen diffs to work when one tire leaves the ground. They work great when you get used to it. Cool build so far. Interested to see what else you do with it.
Looked it up and yeah you use your brakes enable Diff lock
cant believe he didnt google that
@@Icel4nd3r The Hummer only has a diff lock in the center. If you're on moguls then can end up with no traction at opposite corners, and thus the need to drag the brake while on the throttle. It has Torsen diffs front and rear, so this trick is more effective than it is with open diffs (although it can be used to some degree even with open diffs, as I used to do have on my old 4runner).
@@daemn42 Yeah, I did that back in the seventies in Mom's Comet; a little brake drag makes a huge difference.
Yeah at some of the Hummer driving schools they teach you a technique called "modulation" AKA... drag the brakes.
The ideal electric hummer would have one motor per wheel. With this scenario you wouldn't need locking differentials since you can control the speed of each wheel individually.
Like a rivian?
Ideally, but this chassis was designed around an ICE, so it's not possible without a completely different chassis, or heavy modification (which is not recommended for someone who doesn't at least model it first in CAD and perform FEM to ensure there aren't any high stress areas).
@@illuminati229this chasis has dif locks he doesnt know how to use them
It doesn't. The original transfer case had a locking center but the front and rear differentials are torsen differentials without lockers. Torsens are a variation of limited slip but do not work well when unloaded.
The thing he didn't seem to know and genuinely would have helped, dragging the brake really helps torsen diffs when they get a wheel in the air, that can help on open diffs too but the torsen style diff magnifies the effects of that drastically
On this vehicle, I suppose it would be feasible to install an individually controllable brake on each wheel.
i started watching this series in high school and now im finishing my first year of college!! its crazy how far you've come
Always inspiring, the world needs to have more Jerrys working on diverse initiatives.
Soft suspension that brings the tires down to contact the ground will make it feel like a whole new vehicle. It looks really uncomfortable on road and worse offroad. Let some tire pressure out when your offroading to let them squish around rocks and drag the brakes for the Torsen diffs to stop spin
Definitely. Knowing how to work those Torsen sons will be key!
Yeah true, i think the suspension is best fix to ground contact. You can see at around 4:20 - 4:30 theres very little suspension travel, vehicle is balancing between wheels
Watching this project come along is so great!
Man I hope the pace picks up a little on this thing, you have me so hyped.
I would love simple updates, fixing the B pillar, buying and adding the doors, paint prep, painting, etc.
Love watching every step of this project and I’m very excited for continued work on this monster!
It'll interesting if you add some unique features into this car that other EVs don't have. Keep this car as a continuous project it'll be fun to see how far you can push it and how advanced or unique it can get.
Yeah I am also interested in that
I have a feeling that you'll need to lighten up the springs a bit to compensate for the lighter weight up front.
the journey is what that matters, we are watching this video because u took something so ambitious and made it a reality 💯
This series has been impressive, would love to see a breakdown of all the time and costs for this project.
Definitely interested in a price breakdown
I'm guessing the down payment on a nice house.
@@CrypidLore I am curious to know what's the complete ownereship cost of a moderately sized decent house in USA
@@sagarbisht9649 Highly depends on where you live, the average price of a 3 bedroom house goes from 90,000 to 1.2 million. The price variance by state is insane, my comment was based off a 20% down payment on a $475,000 house, so like $95,000
Wow! Been with you on this journey and this felt like a personal achievement! 🎉❤
One of the coolest projects I have seen on all of TH-cam. I loved following the progress and I hope there is more to come
I have had a ton of time in the diesel version of that rig. Anything over 45 and the thing always felt like it was going to rattle apart! BUT I also took it places where I was sure it would get stuck and it never did! Thank you for the videos! They are great!
Amazing build! love how it's come along. Looks like it needs a suspension upgrade though.
Yes, I definitely want to see a cost breakdown.
That high pitched electrical whine would make it undriveable for me. Can you not hear it?
From the looks of things, you definitely need to lighten up the spring rate to keep your wheels on the ground where they'll do some good! It's definitely not hurting for power, just getting that power to the ground.. This is what's needed to ferret out the suspension gremlins. Glad to see you finally got all the CAN bus issues worked out and all the modules are talking to each other now!😉👍
I am glad you are back at this project again, had been a while and I loved the building process. Keep at it.
What could ever go wrong in a massive 30 year old Hummer converted into electric in jerrys garage and taken off roading.
We hear so much about how heavy EVs are... is this one actually LIGHTER than the original, since so much (ie: the turret) was removed?
theres one video he shows how much space it was taking up and how big the diesel drivetrain was as well
Congratulations on getting to the "Mountain Top"! Very informative video. Great to see the progress you have made throughout your adventure. And we know their is more to come!
2 years already!! Well spent, I'll say!! I can't wait to see it done, but i have to be honest.....I love watching your videos specially Project Whisper!! Thanks for sharing with us.
I'd love to see you drive the Rivian through the same road for comparison.
I'm wondering if you could add electronic lockers to the HMMWV to reduce that wheel spin? Also, you should paint up the circle on the roof to resemble a helicopter landing pad, but with a large " D " for DRONE!
It has a much better system than lockers, he just hasn't learned how to utilize it yet.
i watched all episodes of this project from the very beginning 🎉 and im glad to see that car running and functioning well as we all expected 😄 looking forward to see the modifications and other developments on it. Well done 👍
how satisfying it is to finally achieve things we work with our heart and soul right
7:53 "there is a million things left on the to do the list"
Legend has it Jerry will refuse to die until he does all the things he has on the list
To increase efficiency, put on some doors and add a sloping cover to the back (like the CyberTruck). It would increase efficiency significantly over 30mph.
It's been a while! Nice to see Whisper back. Looking forward to more updates. 😁👌
I hope u keep throwing money at this. Insane how long I’ve been following this project and I love it.
good work brother
Love From Punjab India❤❤❤
bro plz dont stop working on this project its the best thing ever looking forward for more
damn it was already 2 years ago that i watched the 1 first video on this !??!! wild how time flies
That squeak (or scream) from the power train while driving would drive me crazy. Cool vehicle!
You should paint that Hatch in your roof with a Helicopter Pad symbol. Nice drone work!
Dang! It looks so cool in his environment >rough terrain< for which it was built! 🤩
i would die for knowing all the insights of this project, every expenses, every data about efficiency and so on, i'd love to see a video covering them
See this up and running doing off-road the feeling only ppl who watched the Hummer taken inside the workshop with the electronic robot can relate
Was very very excited for the project
Hearing the hummer drive through that terrain reminds me of an excavator during construction. Just blasting everything in its path.
OMG making that circle on the roof be painted like a HELI PAD would be perfect!!!
I truly can not wait for "season 2," aka the episodes of refining the rest, visually and functional.
the biggest reason why i love the military hummers is because of their GIGANTIC GROUND CLEARANCE!
Awesome! I'm happy to finally see it rolling. Congrats
Coolest build on TH-cam! Glad to finally see it taking a charge and running under its own power!
Man the project of a lifetime....and we get to follow it along with zach. this is connectivity
Looking at the footage from under the vehicle. there was not much suspension movement at all, leading to wheels lifting off the ground and loss of traction.
Softer springs would help with keeping wheels on the ground / traction as well as comfort.
As per a previous comment, I believe that Humvees have Torsen diffs, and if you briefly touch the brakes while keeping the accelerator depressed, that partially "locks" the diffs.. I am not an expert on that, but research it.. apparently it is quite effective.
And yes, rebuild the B pillar or add a real roll cage. If you ever tip it or roll it (not likely with the width and low centre of gravity, but not impossible) it would be good to have a strong structure to prevent the bodywork crushing..
Great to see it driving.. thanks for taking us along for the ride.
Nice to see Huel doing collaborations with big youtubers. My commute to work was just pass their Tring UK headquarters for the last 5 years. Unbelievable small building for such a big brand.
Of all the EV conversions I’ve seen, I enjoy this one the most!
Once it's done build a off-road camper trailer loaded with batteries and solar panels to extend the range along with charge while you camp
Awesome to follow up from the get go. Please keep updating Project Whisper I can't wait to see more.
FWIW, the trick with Torsen diffs is to apply the brakes while on the "throttle" at the same time. Torque biasing diffs (which the Torsen is) multiply the torque applied to the low traction side by the torque biasing ratio (determined by the angle of the teeth in the worm/wheel inside the diff) and send it to the high traction side. The TBR could be say 2 or 3:1. Obviously if the low traction side takes zero torque to spin, then zero * 3 = zero.. but.. if you apply the brakes and put some load on the low traction side, it'll send 2-3x that to the high traction side. This is a well known "trick" for getting the Hummer unstuck.
Now if you've got a safety cutoff circuit that prevents you from applying brakes and throttle at the same.. well, then you're kinda stuck, literally and figuratively. Most modern vehicles just use the ABS to brake the spinning wheel and that sends 1x the torque through to the high traction side (via a regular open diff).
Awesome as always.Thanks for sharing and taking us along
It's crazy how it's been two years already! I've watched this project from the beginning.
Have been watching along since the beginning, glad to see its finally out n about!
keep up with the diversity in your channel, really enjoying watching your content especially electrical car series, if you can, please do more of it.
The body roll is hilarious! 🤣
I loved watching all the build vids a little while back. Awesome to watch and still awesome. Love it.
ive been waiting so long for this so glad to see it in action!
2:38 cheers for mentioning Heul!! I’m a traveller in a camper and this would be awesome as I don’t have a fridge. Perfect!
Check out the portable fridge video I posted earlier this week! It's expensive but awesome!
Definitely need lockers and some suspension work to get better articulation. Incredibly cool project.
That is one cool ride. Good job on all who made it happen.
I have thoroughly enjoyed every video of this project! The videos of this project on your channel and on Electric Super Car showcase how stunningly difficult it is to MAKE an EV. Thank you!
Super cool project , really enjoyed it from the beginning to the end . Also thanks for adding metric units to your range specification in the video very helpful 👍
💯
I for one would like to see a cost breakdown. And I hope you keep us updated on the continuing phases of this build.
Jebus, 3:50 those mountains man. I wouldn't be able to stop looking at them, one day I hope to move to a place like this.
I am very happy to see that your project was successful. Congratulations! Keep up the good work. Sending love ❤️!
Love your videos my dude keep up the hard work, cant wait to see more of your videos for these types of things...congrats on that mile :)
Hi zak. I am from India and following this project of yours from the start. Getting this beast on the mountain top is some another thing. Happy to see the efforts.
Congratulations on completing the goal of getting to the top of that hill. I've been watching from the start, brother, and it's been a ride. Thanks for sharing, my friend!
gonna be so satisfying getting doors on Whisper. Can't wait to see it sandblasted and painted too. ;o
Love this channel thru the many years!
That's so awesome I'm very excited to see the next video. 👍
Yesss❤
A cost breakdown would be appreciated. Also if you could include detailed parts in it as well. Great build series though!
That is one looovely sound at the 3 minute mark. High pitched sound that just goes IIIIIIII in your ears xD
Always love to see a advert for something I use/love(Huel) love it!
Hearing you gonna add Solar Panel on top of it, I am having goosebumps and sweating my hands in excitement for that day to come. So excited! ❤️XO
The HMMWV's torsen differentials are torque biasing limited slip. If you start spinning a tire, just drag the brakes a little and the diffs will lock up and send power to the tires with good traction.
CANT WAIT FOR MORE WHISPER UPDATES!!!
OMG - Can't wait for the PAININTG part. LOVE all your videos.
I've been waiting for at least 2 years for this video!
Jerry, you are amazing! I cannot believe how much you accomplish in such a short time! Really impressive!
Good luck Zack! Looking forward to the day this Humvee project's gonna be finished.
