!!! UNKNOWN CONTENT TYPE !!!
I’ve posted about this truck before, and I think it is pretty darn cool.

Now, Bollinger has released a series of videos of their truck doing some off-road and in-track testing. But the video production is so annoying, that I will not post the other ones here. Go check them out:

I feel like these people have all heard of off roading, but have never actually tried it.

You may be right, but from what I gather (and what they said in the first video), it looks like they wanted to do a basic test to see if everything worked once you got off the road. Not sure they’ll go for the all-out rock crawling market as the target: this will be pointed at the luxury 4x4's of this world, or in a similar price range.

Does this thing have 4 wheel steering? Seems like that would be so easy on an EV. Just make the same motor/axel/hub assembly for all four wheels. Have a switch in the car for normal, crab walk, and tight radius turning. I know this isn’t a rock crawler, but even on a trail that would be super useful.

Interesting idea, but I don’t believe this thing uses hub motors. They are quite rare in EVs right now.

I now right? Maybe they were shooting with someone’s old phone, and they figured they could hide that with “production values”.

Oh I was thinking it had a motor at each wheel. Even with two motors you could make the same motor/axel assemble front and rear, and just run one of the backwards, not like a motor cares which way it spins.

Am sure an EV truck could do some very creative things! EV has limitations, but also advantages. This is a “through the road” system, where there is no mechanical bits linking front and rear axles.
So via software, they’ll be able to to things you cannot do with a standard 4x4, or cannot do as easily. Like letting one axle freewheel for a bit, or do crazy things like very precise power application at both ends, independent of each other, say rear at 78% power, front at 44%...

But you are right that one motor per wheel would be fantastic! Per-wheel torque vectoring, for both traction and regenerative braking. Each wheel could decide it needs 1%, 100% or -25% torque. All because you are not tied to a single source of torque (an ICE engine).
Imagine the possibilities!

Wow - Water and power electronics do not mix well. Good Luck..

I would think they would plan for that.

Yeah, they thought of that.
The tall ride height and watertight battery enclosure gives the B1 the capability to wade through almost 5 feet of water.

Looking at the stats and features highlighted here, my assessment is way off: they are going for all out off-roader... https://www.trucks.com/2017/07/27/bollinger-b1-electric-truck/
