What Roman is complaining about when asking for a low range/torque converter is a lack of torque moderation. An electric motor can deliver 100% of its torque from 0rpm, so a torque converter isn’t needed. A low ratio isn’t likely to be required either as the final drive (single gear) should deliver enough torque at the wheels to do anything you want. The problem to me sounds more like there isn’t enough control of the torque delivered to the wheels by the throttle pedal. That’s really a software problem. A mode with an extra long travel throttle would help.
That's true, the problem is wheel speed not torque. I've found it myself with my Toyota, even though it has the torque to climb an obstacle in high range, the wheel speed causes wheel spin and you lose traction, so they need a mode that simulates low range by reducing the revolutions in relation to throttle input, as well easing on the torque so that it doesn't immediately break traction.
I love when people argue with their spotter. Bonus points for choosing your own line and dragging your skid plate.
Roman is always stubborn. We know he's the boss of TFL but he always doubts his crew.
Definitely appeared to be some tension between them in this one…
Roman seems so whiny… read the darn manual before filming.
@@stevenle1782 we need Roman to give the keys to the channel to Tommy already so it can head into a better direction
@@USA__WILL Apple didn’t fall far enough from the tree for that statement to be true.
I’m going to be honest with you TFL, that’s the last vehicle I’d take to Moab or off roading anywhere!
Seriously for that price I’d take pretty much anything else.
@@jdhunt1284 I second that 👍
EVs will get better!
The motors will get better, probably Axial Flux Motors will be used as they can be used with a transmission. Ok, Axial Flux Motors are higher torque but have lower revolution speeds so I am serious about the transmission part. The software will get better, but in the mean time maybe they can have a override mode. The batteries will be able to hold more power which means less of them will be needed and the vehicle will get lighter.
Why? GM touted how much testing it went through at Moab. Tests like this keep manufacturers honest. For the price and the marketing, it should be able to handle this.
Last? I would say its the 3rd or 4th
You need suspension travel for off-roading/crawling. Jacking the air suspension to max is severely limiting the amount of wheel travel which is why it goes back to default height when locking the diff I think. You guys can test this for yourself by doing a simple 20 degree RTI (Ramp Travel Index) test. This will show that in default mode you will get a higher score compared to full jacked mode. Furthermore the full jacked mode is not intended for crawling but simply to clear a difficult obstacle once.
There may also be mechanical / engineering reasons. Like wear and efficiency. Unless we're a mechanic who takes the thing apart or we ask GM there's no way to tell
Full Height mode is ONLY to get you over an obstacle that you are hung up on, it’s not meant to drive around on while you’re rock crawling. I think to show what this truck can really do you have to read and understand the manual. You keep trying to do what you would do in a gas truck, rather than learning how to do it in the truck you’re driving, so it’s not surprising it’s not working.
Agree completely. If you are engaging your lockers, it is most likely because you are stuck / getting stuck / having not enough traction. That being the case, having more droop / down travel may very well help
To be fair given the screens it should tell you why you cant engage something when trying to engage it. This isn't the day in age were you just have a button or a toggle and you need to know the steps and procedures. I get it maybe not telling you the first time because maybe you pressed it by accident but if you keep hitting the button to go up and it wont due to setting it should trigger a help prompt. This also tells you the vehicle isn't broken and you are doing it wrong. Is this a toy for the rich? Sure is. But it is the future.
Isn’t there a higher height between extended height and normal height?
I just realized crab mode is actually kinda good for going up steep inclines if you have the room to do it. Essentially you're reducing the angle you're climbing by zig zagging up the incline but you don't have to run the risks associated with making sharp turns.
It’s a gimmick. Period. Unless you can control front and rear separate, all it’s for, is showing off on the road to your house. Use it maybe twice and then forget all about it. Just seems like something else stupid that will break and or throw codes all day. Meh,..
@@96kylar the entire truck is a toy designed for the rich to have fun with, it's not supposed to be affordable, practical, efficient or even that reliable, just fun and it certainly is fun, as almost everyone who owns and reviews it can attest to
The Hummer EV is the ultimate crossfit bro flex truck.
😂😂
A model X with those stupid ass doors takes that prize
Looks a lot like the Honda ridge line clientele,,, to each it’s own :)
Rather be wheeling a $5,000 beater around lot's more fun and no worries with scratches or dents.
Can’t wait to see the review on the 3rd gen Colorado/Canyon twins as I truly think the AT4X and Zr2 will take GM’s top off reading spot, although I guess they’re not really twins anymore.
Agreed, Even the lifted Trail Boss model with a starting MSRP of 38,990 which is a steal for a lifted crew cab pickup with low range transfer case, That and the ZR2 will be a favorite of the overland crowd.
more like cousins than twins...
Hmmm 🤔 maybe Andre,the truck guy (and Mr Truck), should do the truck reviews given he actually reads the available guidance.
BINGO
Roman speaks his mind on these reviews. That’s why I come back for more.
While I respect your opinion, and your honesty...
Roman is the reason I stop watching TFL Videos, that he is in!!
I'm not going to explain...
It's just the way it is, for me!!
That's my $3.73 opinion (current price of regular gas, where I live).
@@Oldskul-iz4om He employs a great crew and gets on well with them. Got to respect him for that at least.
@@Oldskul-iz4omWhy is that? (Your not watching videos with Roman in them)
I don’t always agree with Roman but like that he speaks his mind in the sense that he does not appear to be in the pocket of a large corporation.
@@Malc664 employs a great crew(then proceeds to doubt their intuition and guidance, decides to argue with them and plowes on doing his own thing) usually damaging things.
Dudes stubborn and is holding these videos back. Most of these are boring and only getting worse.
Dude literally started bitchin and complaining to the point it seemed like he was gonna pout, when all he had to do was read the GIANT DASH!
Wow, what an expensive pile.
The base trim T-Rex TFL owned is light years ahead of this truck, and 25,000 dollars less buys a lot of 5.00 a gallon fuel. With 3 minute fill up times.
This channel has grown because of good content and editing not from driving abilities or actual car guy knowledge
It's a badass truck, but I'd like my off roaders to be simpler. Fancy electronics are nice for cruising and having all the creature comforts but if you're out in the backwoods you don't want something to fail and you can't get home. I like my JL Sport. I have a 1.75" spacer lift and 35s and I could do everything you guys did today and more, for a third of the price. Once I regear and put on some high clearance fender flares I'll be able to do 37s and then I'll really be in business. I'd like it to be known I'm not an EV hater by any means (they're 100% the future). Keep the content coming! Safe trails!
These things are going to be maintenance nightmares as they age a bit.
Extended ride height puts the cv axles at an extreme angle, it probably prevents the locker from engaging to protect the axles when that high.
It would be great if the display would show explanations like yours when things didn't go the way you want so you wouldn't be left scratching your head.
It would be cool if you could compare this off road with older Hummers.
All they had to do is ask because there's an outstanding offer to get an H1 head-to-head with it :)
It wouldn’t have a chance
Too bad Andre sold his Hummer!
The crab mode might be useful when trying to thread around trees on the trail. Maybe something like crab mode would have helped Andre avoid the scratch on the rear fender of his truck in the Colorado mountains.
My thoughts exactly.
Maybe just maybe think about reading the manual before taking it off road.
The hummer ev has some clever engineering, but for actual offroading it seems like there's a lot going against it. Heavy, large, not much suspension travel and the electronics are too busy. Give me simple 4lo, lockers, clearance and light weight.
Great video. I really wanted this level of video quality for the G-Wagon^2 videos, that vehicle looked insane in Moab, never to be repeated by anyone again, lol.
You can only see it here - on TFL !
As always great video, I think you really help out a lot of people with your testing & reviews, keep up the good work. 👍🏻👍🏻
Sounds like the Hummer needs a software update and stickier tires, but I imagine the Duratracs were a very intentional choice because of the weight
Okay, so we know that it is heavy, but my question is, what the "THIS" happens moment (in the title)?
This is like when a xl steroid filled bodybuilder does yoga.
Terrain mode is the one you want for Moab. Turning into Grumpy old men 🤣.
I honestly can’t tell if this truck is glitchy or if Roman just hasn’t read the manual or learned about all these modes and features.
He definitely hates it. That much is clear.
IT WON'T LOCK!
Ahahahah
It seems to have done quite well, despite Roman's constant grumbling - lol. Maybe he was just cranky from not finding his favorite socks that morning.
Seems to me that you guys are playing around with screens and buttons more than you're actually driving over obstacles. The only mode my H1 needs to get over that first obstacle is 4L.
I want to hear Andre say "get to da choppah"
Andrey doesn't always have a choppah, but when he does, he gets to it.
My 2 door Rubicon feels too heavy at times, I can't imagine having to offroad this tank.
I learned something more important than you. Never get underneath that vehicle. Thanks guys. Great video
Loved the monkey football aspect of this video! 👍
"It's cute, but it's not helpful" Seems to sum up this vehicle pretty well.
Never ever any electronic PC on the wheels for off roading :D It just a marketing joke. Those managers are laughing at people who buy it.
Roman you guys need to do some creek crossings with it. I’m waiting!
Fun, informative video. Moral to this story? $113k, governed at 106mph, a wee bit complicated for me. I prefer simplicity and value, 2 things that don’t apply here - thanks TFL for being real world Guinea pigs
Question? How is this the best off roader when it is so compromised? Seems like an expensive GM miss
Agreed, it’s just not that much fun off-roading in something that costs over a years salary and simplicity is always better.
I call these EV's a failure
I don’t think it’s a miss because GM made a super truck to compete with these rigs from other American automakers while using EV technology for consumers to experience. This is coming from a guy that will never be able to afford these expensive trucks and doesn’t like EV technology…
I didn’t say it was a miss. I think it is a big company learning how to use new technology but applying old standards and not quite knowing how to get there yet. I think when the dust settles a lot of today’s issues will either be less or non existent
These things are changing hands for close to $200k..
Generally you can change the response of frequency converters (that control el. motors).
They could install a low range as sometimes electric motors with gears are used in industry. (For different products)
No….
@@CoDplayer458458 why no? In industrial use it is not so unusual, to have different or sometimes adaptive parameters for eg. speed regulator loop, etc.
Do you guys read the owners manual to determine the functionality, or is it just by experience? Seems like the manual could answer some of the "why does it do this" questions.
The owners manual for this thing is probably 10000 pages long. That might be why there's not an actual hard copy of the manual, because all the trees would be gone. This vehicle is overly complicated is my point.
But but but
WHY DOES THE OWNERS MANUAL DO THAT????
@@lesalbro8880 for some reason I feel like that's the EXACT reason they'd do something like that
It's soooooo dumb they'd try convincing you your really going green by getting an EV 5000 of those pages would be about that.....
I mean it helps a lot when you read the Owners Manual that explains the Features and options of how and why. It could probably do all you wanted to do in a mode. You didn't know????? I always post this when some look lost and bash it????
I remember watching another channel do a trail with an electric Jeep in the convoy, that all-or-nothing torque effect made it really hard to manoeuvre through the technical stuff. Also, that one pedal mode must be terrifying on a slippery descent (the type you would normally be advised to stay right off the brakes for).
I have a Wrangler 4xe and agree with Roman. Electric still needs a lo range. When I put my Jeep in lo it can crawl up anything but in hi it needs a lot more effort and that can make it harder to modulate. Gears always help.
Jeep is going to retain a low range but they won’t be taking the traditional approach 🤐
Look for a huge hint at EJS next year and the full announcement at SEMA with deliveries for 25
You mean a low-range algorithm?
They need to add a craw control type mode. Normally the accelerator pedal controls the torque applied to the wheels, which is what you want for normal driving. But when going up a ledge you need maximum torque to go up it, then you instantly need almost no torque once the wheel is on top of it. Letting the electronics control the speed/position of the motor instead of the torque accomplishes that faster than any human driver could react.
This is terrain mode. It holds the brake while you push the accelerator. They also didn’t air down. Which the hummer has an off-road assistant to help you.
I'm super excited about the SUV version.
A vehicle suffering adiposity on 35' tyres. I don't want to think about soft terrain. Well done GM !
TFL does the most honest and useful reviews on all vehicles and very few do that. EVs are great if you don't drive far, offroad, tow, have time (hours) to wait to recharge, and a F-ton of money to spend. Oh and you still need a gasoline or diesel powered vehicle because if there is a hurricane or some event you have to flee from and the roads are congested....good luck in an EV.
That truck has waaaaaay too many issues.
I feel like the 1st obstacle could have been made. Also I'm curious how the SUV hummer ev stacks up against other suvs.
It definitely could have. They stress me out sometimes with how they nit pick every obstacle
Love you called the pitch out !!! 🎉🎉🎉🎉🎉🎉🎉
Much rather have a Colorado ZR2 there...
Do the same with the R1T and the F-150 lightning (with better tires perhaps)
The regular lightning is not designed for moab. Ford will be making an EV “Raptor” in Blue Oval city in ~ 18-24 months
@@shitloveaduck I have ten Pros as part of my work fleet. They are absolutely fantastic at doing what they are designed to do but offroading aint it
The F-150 Lightning would NOT be able to go on this Fins-n-Things Moab trail due to lack of clearance.
Looking forward to a second trip once you have more experience with the Hummer EV.
One peddle driving seems like it could cause some problems when you are coming off a ledge or shelf. The bounce/bottoming could cause you to push down/forward on the throttle just when you wouldn’t want to do that.
I've found one pedal in my Tremor to have exactly that problem on steep declines (around 19°) It's a cool feature sometimes, but it seems like the transition from brake to throttle isn't very smooth on a slope, with a pretty hard surge forward and then back. I used it a couple times in the mountains, then left it off.
When you get leveling system unavailable, reset accessory battery system or front locker not working. Usually fixes it .
GMC should have "Hummer for dummies" video you can watch at the dealership before you buy it...
Good idea,,,it will sure stop a lot of needless sales to serious off-road users.
I'm 16:00 minutes in, and the best part of this video is watching Roman becoming more and more frustrated and disenchanted with the Hummer. Keep the Hummer/EV vids coming...they continue to solidify my decision to not go that direction!
That is the perfect mall crawler and no off-roader
You can use crab mode to move back and forth to shift yourself to the right or to the left by going forward and backward and then turning Wheels to get a better line
You guys are doing a good job with it. Show it more, warts and all. Run a PowerWagon and Tremor with it next time
WIll do! Thank you for the feedback.
@@TFLoffroad put 37s on
I would love to see some kind of battle between a gas hummer and the ev hummer. Would be very fun and interesting
The ole military Hummer H1 from Iraq and Afghanistan.
Please stay tuned!
@@GettingthruLife NOT GAS. H2 and H3 Gas hummers would do just as poorly.
I have found that when the Hummer will not raise or lower, if you drive a few feet forward and back then it will allow you to adjust the height.
It is not basically efficient. Calm down now Roman.
I know they don't sell these in my neck of the woods (from Africa), but I just cannot see this work as an off roader outside the US (even there...). If you look at Africa and Australia, no electrical infrastructure to really speak off, and 1000's of kilometers between our stops would make it unworkable. And that is not even the biggest issue, imagine you are on a 2,000 kilometer trip, in the middle of nowhere, and the electronics starts acting up? Just as big NO as far as an adventure 4x4 goes... Will take the most basic Ford / Jeep / Toyota every of day of the week if I actually had to do remote wheeling.
BATTERY IS NOT THE ANSWER for everything. Any LIQUID FUEL has more ENERGY DENSITY than today battery.
One of its biggest flaws is the weight. Hopefully GM will have some updates to improve its offroad driving.
that weight is how you get your range. the thing weighs so much because of the large batteries. shouldn't this get a tax for having so much lithium?
First it was a gas guzzler, now its too heavy. The poor Hummer can catch a break.
. In the canyons of LA it will be a real aluminum can crusher and able to leap tall curbs, that's the market it is designed for.
Love this channel, truly test the vehicle, you guys rock!
I think it drops the truck down when the lockers are engaged because of cv axle angle. Maybe the extra train on drivtrain strain
First, Roman has to realize that part of the limitations of the Hummer has to do with user error. As experienced as he may be with rock crawling, this is a different type of vehicle that take some getting used to. It think that should be the biggest takeaway from this demonstration. Simply being different doesn't mean not as good. There's just an additional learning curve.
In any event, the D-ring sticks out another 4" beyond the bumper in a location where even fractions of an inch matter. It currently can flip down, but in this case, it might have been better for it to flip up. Maybe future models it will be able to flip up over or blush into the bumper.
Would your crab mode help on a trail with tight turns like black bear pass. Or is that thing to wide to even try it
Been there, that's a pretty tall rock for any stock vehicle.
Crab mode would be good if youre stuck in a ditch against a tree. A common occurance for hummer owners
It will be fine for Bruce in Flordia to take his two jet skis or boat to the launch ramp
Seems like a lot of stuff that can be solved with software updates, which is definitely good news for anyone considering this. But, as GM typically does, they put out the bells and whistles and don't seem to do much testing (or just don't care).
These are off roaders, but GM made Hummer EVs for the purpose of having a super truck with future powertrain technology for people to enjoy and show off, not to bash rocks. TFL has continually showed that 4Runners, Wranglers, and Broncos are the ideal choices for going off-road, they are way cheaper and the base models with good tires will do a lot for enthusiasts…
On the other hand, who does build a vehicle so owners can "bash rocks"?
It is cool looking.. I'll give it that. If GM would put their Duramax I6 diesel in there and reduce the weight (and price) it would be a worthwhile vehicle. Overall, looking forward to TFL selling it and moving on to something more interesting.
You should make more of these videos
You know hummer is face palming, who are these soccer moms killin everything awesome about our hum
Maybe I should keep my Hummer EV SUV Edition1 reservation. I have been hoping any problems get worked out with the pickup.
It should come with a manual air pump for when the one of the car fails/overheat.
Like the ones people use to pump bike tyres, soccer balls... 🤣
I definitely wouldn't learn about my $112,000 truck before offroading.
It's a fancy expensive toy that the rich can drive around to show how great they are.
You’ve debunked all the gas off-roaders who say they will need a 1,000 mi of range to be able to depend on an electric off roader. Driving slow and stop and go is where an EV is most efficient. 😊
That air suspension has more issues than a Land Rover air suspension 🤣
Most off road worthy vehicle gm has ever tested my ass 😂
And the charade continues. 🤣
The truck did great but for that much money, I wouldn’t do that. To Expensive to replace and repair plus the system itself is to sensitive. But overall great review y’all.
Only TFL uses lockers on absolutely unnecessary scenarios.
Beating up on the Hummer. But for $115,000, I expect everything to work all the time.
Locomotives with DC motors tended to be geared for different uses. It was controversial when AC motor locomotives came out as engineers felt they could use electronics to cover a wide load speed use. You could use a locomotive to haul coal or , in NA, haul medium speed passenger.
That's good point, the way how diesel electric locomotives can control very slowly... for rock crawling we need the smooth low sensitivity control, but also ability to use the pedal for quick increase to finish obstacle
Electronic drive will work better when manufacturers realize that a pulse is better than steady torque ... initial traction is best and once that is lost its best to just start over ... thats why the pulsing power of a single cylinder motor works better than two or four cylinders off road
Maybe y’all could do a Prius next about the same awesomeness
Tech bugs aside, it seems clear the Hummer is just too heavy to be a good mixed use offroader. You can't hide mass no matter how many tech goodies you have.
If Colin Chapman weren't already dead the sight of this thing would do him in!
In terrain mode does it roll forward or backward when going off the throttle? Ideally it should have drag brake that keeps it from rolling.
Well Roman did state the vehicle doesn't move unless you depress the accelerator.
@@krane15 Yeah but when trying to climb the steep ledge it seemed to roll off.
I think this hammer needs years and years to improve
Too much technology can be a bad thing as seen here. We were at peak off roading with the Zr2 Colorado and the Gladiator rubicon. Solid and reliable for off road use. Then the ev hummer came around.
Well, I'd argue peak is the JL Rubicon, not the Gladiator with it's giant rear overhang that drags over everything but yeah, this is no off-roader. It's for posing.
This is basically a working prototype
All these rocks seem more pokey -Andrey 😂
so the hummer suv should be better with the shorterwheelbase
That thing is ridiculous. It’s best suited for showing off in the mall parking lot or in line to pick up the kids at school.
Between the weight and the computers trying to think for you, this is a no for me without even having to discuss electric vs gas. Heck, you could get pretty awesome build in most other 4X4's and have enough left over to outfit your home with solar, or buy an efficient daily driver if you want to feel like you're helping the environment or whatever. Especially considering people are offering near 200k for these early Hummer EV's.
