By the time the wheel gets up to 2 RPM, you have doubled the HP output if you are keeping it at peak torque. - ICE is a bit more complicated. At idle RPM, generally, you get significantly less than peak torque. So if you take your foot off the brake and then hit the accelerator, you start off with comparatively low HP (relative to an electric motor with the same peak torque) and the engine needs to spool up to get in the peak torque range. This is why you often will feel a slow acceleration followed a second later by an increase in acceleration. Further complicating it with automatic transmissions, is you can give it a little gas before letting off on the brake. The torque converter will allow the engine to spool up and then you have more torque available immediately.But really, once you can spin the wheels, more HP doesn't offer much advantage for the average user.16" clearance...yeah go check out any jeep club. Then go check out your average pickup buyer. It's not hard to build a 4x4 that will climb walls but for most users, climbing a 6" curb on rare occasions is about the worst they will see. Really big heavy full size pickups with stiff suspensions are lousy for off road.

And as much as 100% torque is available at start... reality is the torque is limited electronically or you would just roast the tires and hardly go anywhere.

Lots of talk about a vehicle no one has yet and not even being built yet.Maybe they will get around to it like the class 8 truck. O, wait thats not being built yet either.

Big deal, a one off. Can you say "Prototype"? I knew that you could. Let's see a couple others in operation. Or would that be a bit more difficult?

TFL Truck testing the 7.3 Ford gasohol V8 / 10 spd / 4.30 ratio in Loveland Pass with 18,000lbs trailer. aka THE IKE GAUNTLET OMG!

Anyways the grade pulling fuel economy should give a person range anxiety - dividing what they got into what a 40gal tank...

7.3 Ford gasohol V8 - 18,000 trailer

If you thought that was bad, wait till you see the instantaneous range readout on a Cybertruck pulling 18k lbs up that grade.

I'll place my bet at 30 miles, 10% of its empty cruising range.

I should have explained myself better, my comment was based on this quote from the article;

“We want it to be something you could use to tow a boat, a horse trailer, pull tree stumps out of the ground, go off-roading and you don’t have to worry about scratching the paint because there is no paint. You could just be smashing boulders and be fine.“

Having a heavy off road background I found that statement a bit funny. I do wonder how the pack protection will be accomplished.

No need 'splaininng, yours is a legit comment.:W

I would be also be interested having the Cybertruck compared and field tested in real battle-extreme off road conditions.

Interesting!

I am way past off roading and except when having doing extreme part of it in my farm when the steep non-road turn into snoot of mud, I just want to have my Cybertruck not being stuck or not careening off the snow and ice on the road while pulling my RV.

I'll be interested to know however how those more adventurous guys try it in Moab.

It will always be on a disadvantage with each long wheelbase. However, it will be ahead in power and torque with anyone with zero mods.

I agree that I would want a CyberJeep type vehicle for actual off road adventure.

I still want to read some reports on how the electronic balancing of torque and wheel speed actually performs off road. Basic sand, snow, mud is fine but climbing a dry riverbed or such is a bit more challenging.

Also curious how the air suspension will adjust to the terrain vs a modified Jeep.

Cybertruck versus Rubicon or Fordyce Creek trails would be interesting to watch.

That would be like comparing my 8,000 lb Ram 2500 CTD to my 4,500 lb Jeep JK Rubicon. The Cybertruck would not stand a chance in most off road situations just like my Ram would not versus my JK. Too heavy and too big.

I’m not in the know much on extreme 4 x 4 Ing. I think it’s kinda cool watching the you tube videos though. First impressions are it would be a pretty big vehicle for those applications. Cybertruck are the size of a F150 with 6.5 box. Too big????

We use to have a wrangler. It was small and could get into some crazy places.

The charging infrastructure has been there many years in that area.

Vigor is making/retrofitting hybrid ferries for WA state which may eventually turn to fully electric.

There are smaller passenger ferries running that are fully electric and the Danes have put the first small vehicle ferry into use.
