The Hummer EV Takes On The Out of Spec Hill Climb Challenge! 

I love the influx of Alyssa cross the channels. It's like yall are the dynamic duo.

@Out of Spec Overlanding Long time subscriber and fan of the channel. Really love all the tests and reviews. But please find an area where you can demo baja mode other than tearing up the parking areas at trailheads. A lot of work goes into maintaining these areas and drifting circles in these areas (be that ATVs, UTVs or vehicles) really tears them up. Hoping you can find some OHV areas where you can hammer on it, because I love seeing it and love hearing the giggles while you do it, but just not tearing up the parking areas. Thanks.

Per the GMC website, one must be in Terrain mode to engage the front locker then hold the front locker button for five seconds: To Engage the Front Locker: Make sure vehicle is in Terrain Mode by using the Driver Mode Selector dial. In Terrain Mode, both the front and rear axles can be locked for maximum traction. To engage the front locker, press and hold the centerstack button that shows locks over both axles for 5 seconds. If the rear axle was not already locked, it will lock together with the front axle locker. Note: The front locker automatically disengages at speeds above 15 mph. Note: The rear locker is available at speeds of up to 50 mph in Terrain Mode. Note: The lockers can be manually disengaged with a push of their corresponding centerstack button.

The first clip totally reminds of me of my electric RC trucks, so fun

I know that electric motors have all their torque at zero rpm, but on a couple of those climbs you had it full throttle with no movement. I feel a transfer case with a low range would definitely help out, as you could ease up difficult sections without having to floor it.

This has been one of the best off road tests of the Hummer. Would definitely have loved to see how the drifting looks from the exterior. Great job

Nice! I have Edition 1 #580 and love it - best offroad and onroad truck so far for us. Still have a Rivian preorder for an R1S but may not take it, instead take our Hummer SUV 3X order. All this capability along with the convertible, the tech in it all works really well, and its roomy size makes is such a cool truck.

I think extract mode is for when you need an extraction, not for wheeling up. If you get stuck in extract mode, you are screwed. Get stuck in Terrain mode and you can use extract mode to free yourself

Please get exterior footage of your drift angles. Because i bet it looked crazy in that behemoth.

Ooh what I wouldn't do to be able to test these EVs out off-road with y'all. Great content!

The software for the off-road traction management seems like it's in beta. Traction aids like lockers, low air pressure, gearing are about allowing the driver to traverse difficult terrain with better control. Having the throttle wide open with no forward motion is not having control.

Hello from Russian! Hummer the Best! My Dream car...

For the nerds. It‘s not any rocket, it is the Saturn V rocket. The one from the Apollo missions. Not many rockets with a 5 thruster configuration. 🤓

Per the Hummers Owners Manual you need to hold down the button for the Front Locker for 5 seconds, owners have found it's more like 8 seconds to allow it to engage.

It's so creepy seeing the back wheels turn!

@4:52 'THROTTLE' The ICE Age hangs on!

This thing is so heavy it sure wrecks the trails

"Should we get one?" You've got to get one now.

extract mode = Disney indiana jones mode

@2:46 Kyle: '246 kWh Battery' Me: 'GROSS'

That is totally Awesome. Definitely out does my current truck. Fun review.

in shocked it didn’t break down. seems these have been breaking down on reviews lately

Great job on the video Kyle! Thanks for making it.

Stick a genset on the back so you can get some recharge when you have stopped part way into your adventure.

Did you try putting in neutral before locking the front diff? That might be why it didn't want to do it.

Love your tests and the video itself. To be honest: from your main channel I have seen a couple of videos but this one it's more engaging for me. Keep the good work!

That thing is so cool lol

Whithout vrum-vrum looks like big rc-model

Hey Out of Spec, I just discovered a RU-vid channel where a guy over in China modifies Teslas to make them off roaders. It's called Yiche Garage. It's definitely worth checking out.

I wonder if you used the L for low range on the drive selector or just left it in D the whole time. Update: I screen-shot the inside views of this video and it appears he drove in D the entire time. I'm pretty positive he would have gotten more torque on those moguls.

You need to be in natural to engage the front locker

What a balls-out wild-a$$ hunk of stuff! Nothing exceeds like excess.

Fun video! I have yet to see anyone to get the front locker to engage.

If you could only pick one to daily and offroad, Hummer or Rivian? I feel like the at home charge rate/efficiency of the Hummer would limit ease of use for daily driving and home charging, but it's marginally better offroad?

take it to the sand dunes next

Love that you touted physical lockers the whole time and it didn't work once. GM products for you.

Make sure to boot down that humangous computer after playing with it 😂

After checking, it looks like the Ultium NCMA cells are 103 Ah gross capacity, which would put the GMC HUMMER EV's pack at 219.5 kWh gross.

Great video. Where is the other channel that he is taking about?

Why will the Hummer EV SUV charge slower then the pickup truck?

Howdy folks you know it was about 3 months ago you guys did a video series when you went up into Alaska and you left off when you were in Dawson Creek at the beginning of the alcan highway and there has not been a part two which at the end of the video says it will not take as long so maybe you can give us a idea as to when that video come out on your trip to Alaska through Canada in your Mercedes sprinter van or is it not going to be completed and be left off?

Bellissimo incredibile modello potente

I don't see it that good if it has such huge power limit in raised mode... EVs for offroad need some sort of low sensitivity modulation simulating low range where the power actually remains with proper left to right delivery too, i mean this is worse then good break based AWDs... It's ok though they can improve

But where oh where is the Quadrasteer Suburban

I would really love to see a Range Rover on that same parcour mate! Range Rover is king off-road

I would not be surprised if the front locker is intentionally disabled until validation testing can be completed. Mechanical lockers can easily be damaged or damage other components when used under certain conditions. With enough software intervention you can minimize the number of failures and therefore warranty claims, dissatisfied customers, etc. But that takes time to develop and validate. For example, you can limit motor torque and alter brake interventions for TC and ESC, for a given steering angle, vehicle speed, potentially axle weight, etc.

Which mode when you were in the slip test?

You're the 3rd video I've watched with front locker issues... another one couldn't get extract mode to work either on the main center screen but it showed working in the driver dash screen. They definitely have some bugs to work out. The virtual locker is also a bit of a let down, you wouldn't think they would even use the word "locker" if it couldn't come that close to making the electric motors work together evenly. Great video and still want the Hummer EV, I believe these are hopefully just Gen 1 issues.

Where are the other parts of the Alaska trip?

What's the name of this area?

A lot of truck for like 20k more than Rivian.

How big is the battery? 10 Nissan Leafs!

full throttle and it doesn't move? Wow so glad I didn't get one of these. This is no crawler.

100K$ For Crab drive 🧐

Man. Disappointing. Those software “lockers” seem kind of crappy.

G-arbage M-ade C-arelessly

I thank you so much for your honest test and for your sympathie but Realy i realise that these électric 4x4 are fake 💨💨💨💨💨💨💨💨in real off road situation.... Anywhy i thank you 🙏✌🙏✌🙏

Put the Model X through it!!! PLZ

The suv version will weigh even more… lol, atrocious to drive something that heavy that fast 🤮 lightweight is the key , eventually ev’s will have this feature then it will be a more attractive idea

my 2000 honda crv does better off road then the hummer lmao

You need to be in natural to engage the front locker
