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 👍
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.
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.
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
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.
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..
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 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
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!
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.
I drove a "Hummer" (actually a M998 HMMWV) for 11 months all over Bosnia in 1996. It went everywhere. With the exception of going through about 8 half-shafts over the 11 months it was a beast.
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.
@@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).
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.
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).
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
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!
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.
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.
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.
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
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
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!😉👍
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.
Proud of ya bud. Good news. Torsten does brake acceleration modulation. Since you didn’t put a motor at each wheel and the diffs are active, you can depress the brake pedal when you have wheels pin and it will stop the spinning wheel and trick the rest into thinking it has traction. The. Other wheels will pull. Drive two footed off-road.
@@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
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.
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!
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.
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
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!
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.
Hello, It does have a Torsen ---Limited Slip Differential supposedly (That technology has been solid for 30 years) You can see it working perfectly when the wheel comes off the ground and you are moving forward. I think the wheel started spinning because you were rolling backward during that time..
I was wondering when you were going to take it offroad. I love the project and wish I could do the same. For now, at least I can enjoy my H3 Hummer. Wish I could convert it, but not enough money to get that done. However, watching your EV Humvee conversion is good enough for me. Excellent job!!!
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!
I dont think its the suspension as much, you can see it working going over things. but it is not loosing its articulation. I believe it is the throttle response as well. I know you know your numbers well... itll be fixed soon. SWEET!
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!
A tip for the throttle. I had a motorcycle that did the same thing, jerky throttle over bumps. Brace your ankle against something solid. For a motorcycle I would stick my index finger out over top of the brake to keep my bike from jerking due to the torque.
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).
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 👍
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!
Aside from locking diffs, you also need WAY more articulation. Guessing that weight reduction has you driving around at full droop almost. Being able to keep the wheels planted is key. Beefy sway bars with electrically disconnectable ends would keep it safe on the road and let you get more articulation too. Or pull them out if it has any. Softer springs are definitely on your shopping list along with lockers though.
Zach, while going up that hill, you were one wheel off the ground a LOT, that means you must have the Suspension changed to make it Articulate properly to keep all 4 wheels on the ground.
Oh my goodness my back hurts just watching, that suspension needs to be softened up! Looks like driving a steel workbench up a mountain. :D Love this project, i have a 4x4 converted ambulance rv. I hope that in a decade its way more feasible to do a swap like this all thanks to the awesome work you do!
Make a solar array. Sliding solor panels. The top layer can always be charging. When you stop for lunch or a siesta. You slide out the top panels revealing the lower panels. Make it two or three panels deep. And the panels would double as shade awnings.
A pleasure to help!

That high pitched electrical whine would make it undriveable for me. Can you not hear it?
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
Amazing build! love how it's come along. Looks like it needs a suspension upgrade though.
Always inspiring, the world needs to have more Jerrys working on diverse initiatives.
What could ever go wrong in a massive 30 year old Hummer converted into electric in jerrys garage and taken off roading.
Of all the EV conversions I’ve seen, I enjoy this one the most!
I'd love to see you drive the Rivian through the same road for comparison.
It's crazy how it's been two years already! I've watched this project from the beginning.
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.
Yes, following up this project from beginning interested to the cost breakdown... Really looking forward new changes for the humvee .
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.
One of the coolest projects I have seen on all of UA-cam. I loved following the progress and I hope there is more to come
Dang! It looks so cool in his environment >rough terrain< for which it was built! 🤩
Man the project of a lifetime....and we get to follow it along with zach. this is connectivity
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.
Jerry, you are amazing! I cannot believe how much you accomplish in such a short time! Really impressive!
You should paint that Hatch in your roof with a Helicopter Pad symbol. Nice drone work!
Awesome to follow up from the get go. Please keep updating Project Whisper I can't wait to see more.
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
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!
how satisfying it is to finally achieve things we work with our heart and soul right
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.
Hello, It does have a Torsen ---Limited Slip Differential supposedly (That technology has been solid for 30 years) You can see it working perfectly when the wheel comes off the ground and you are moving forward. I think the wheel started spinning because you were rolling backward during that time..
That squeak (or scream) from the power train while driving would drive me crazy. Cool vehicle!
Have been watching along since the beginning, glad to see its finally out n about!
I was wondering when you were going to take it offroad. I love the project and wish I could do the same. For now, at least I can enjoy my H3 Hummer. Wish I could convert it, but not enough money to get that done. However, watching your EV Humvee conversion is good enough for me. Excellent job!!!
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!
I dont think its the suspension as much, you can see it working going over things. but it is not loosing its articulation. I believe it is the throttle response as well. I know you know your numbers well... itll be fixed soon. SWEET!
I am glad you are back at this project again, had been a while and I loved the building process. Keep at it.
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!
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.
A tip for the throttle. I had a motorcycle that did the same thing, jerky throttle over bumps. Brace your ankle against something solid. For a motorcycle I would stick my index finger out over top of the brake to keep my bike from jerking due to the torque.
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).
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 👍
💯
It's been a while! Nice to see Whisper back. Looking forward to more updates. 😁👌
This man is so humble. Not only that he BREAKS (glass is glass and glass will break), he BUILDS (an EV Hummer, a school, a library)
Always love to see a advert for something I use/love(Huel) love it!
Air Ride, some lockers. And adjusting that electronic throttle so it doesn't bounce on ya(slower response) Can't wait to see where it goes next!
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!
Lockers would be nice.. Thx for sharing....
Good luck Zack! Looking forward to the day this Humvee project's gonna be finished.
Aside from locking diffs, you also need WAY more articulation. Guessing that weight reduction has you driving around at full droop almost. Being able to keep the wheels planted is key. Beefy sway bars with electrically disconnectable ends would keep it safe on the road and let you get more articulation too. Or pull them out if it has any. Softer springs are definitely on your shopping list along with lockers though.
Zach, while going up that hill, you were one wheel off the ground a LOT, that means you must have the Suspension changed to make it Articulate properly to keep all 4 wheels on the ground.
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
I truly can not wait for "season 2," aka the episodes of refining the rest, visually and functional.
Love it!!! What Could Possibly Go Wrong?!!
Oh my goodness my back hurts just watching, that suspension needs to be softened up! Looks like driving a steel workbench up a mountain. :D Love this project, i have a 4x4 converted ambulance rv. I hope that in a decade its way more feasible to do a swap like this all thanks to the awesome work you do!
Make a solar array. Sliding solor panels. The top layer can always be charging. When you stop for lunch or a siesta. You slide out the top panels revealing the lower panels. Make it two or three panels deep. And the panels would double as shade awnings.
Definitely need lockers and some suspension work to get better articulation. Incredibly cool project.
A cost breakdown would be appreciated. Also if you could include detailed parts in it as well. Great build series though!
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
Awesome as always.Thanks for sharing and taking us along
Definitely need a cost break down! Love the channel and build, Zach! Been watching since day 1
I loved watching all the build vids a little while back. Awesome to watch and still awesome. Love it.
Coolest build on UA-cam! Glad to finally see it taking a charge and running under its own power!
Great job. But you need weight in the front axle, maybe another battery pack in the front, that will help with traction and some ARB locking diffs.
I ordered Huel last week! It’s so good! I love their Drinks! Also their hot and savory meals are so good!
i hope this series continues and not like other youtubers that show it a year later randomly laying around not having moved since
This is one of the coolest series I’ve seen! Awesome job!
Awesome! I'm happy to finally see it rolling. Congrats
That's so awesome I'm very excited to see the next video. 👍
Yesss❤
