This pull demonstrates the limitations pretty clearly. You would need to top off the charge on your truck off before you started up the hill, then recharge once you got to the top, assuming that capability exists. When you put all of that together, it could take you half a day to get to the top of hill and able to continue on your drive. That is not practical. While this is a steep climb, there are many climbs in the USA that would also create a similar issue. Plenty of work to do here.
Respectfully, going down hill the truck would gain charge--so there is no need to charge at the top of the hill.

Power certainly isn't issue, but batteries and charging certainly is an issue and will continue to be one for some time. Likely most here can remember when computers became a practical home purchase, you could buy the great computer at Best Buy and it was obsolete before you made it home. I suspect this will be the situation here as well. Unless you dont pull anything to speak of, buying one of these initial release EV pickups will very quickly be obsolete as the tech gets better and better.

I can remember hauling a wrecked Harley over that hump in a Chevy about the same era as that Ford. I-6, carburetor, and 3 speed. And look how IC had been evolving before that pickup was built.

You are right. We have been denying the need for change for so long, getting such a late start, the only real chance is to return to the NEED for transportation we had in late 1800s

From this test it's clear that electric trucks are along ways from being used for tow vehicles including the charging stations that are not layed out to support charging a truck with a trailer in tow and this truck is not compatible with the Tesla charging stations is another big flaw.
Not sure how to quantify this test but I would consider calling it an epic fail.

I think it did ok considering its a sporty truck,not a hauler.
Surprised they didnt show the COST of recharging that truck.
No doubt its way cheaper then diesel or gas ie less $$ per mile.
Ad to that low cost of maintanance and no stinky exhaust and ICE doesnt seem all that apealing anymore.
Im sure Tesla CBRTK will do better then Riv and their SCharger network
Is also better.

Time is money and any ICE truck makes that trip plus the entire pull and back and doesn't require refueling. Having said that even if Rivian doubles the battery capacity it still doesn't travel far and will require a long battery charge. And again time is money!

As seen in the video, the truck gained almost no charge going down the hill. It took 17% battery capacity to climb the hill, but only regained 2% coming down. That really highlights the aerodynamic drag penalty that must be paid when towing a high profile vehicle. It may be true that a carefully engineered EV solo will regain going downhill much of the energy spent going uphill, but add a huge amount of aerodynamic drag behind it and that efficiency goes away.
I believe that electric vehicles are the future and their time is coming, but some people are so excited about them that they refuse to acknowledge physics. I was at a Harley dealer a while back chatting up a salesman about the Livewire electric motorcycle. He told me that if you rode a circuit that had lots of up and down, when you returned you would actually have more charge in the battery than when you left. Sadly, I'm sure some people would actually believe that.

Does anyone know how many kWh's was needed to go the 8 miles up the hill?
I thought they said 135 kWh. But that may be what they used on the trip from Boulder.

I think they said the battery is a 135 kWh battery. That jives with what I have read in unofficial sources.
Re the cost to recharge. I don’t know what ELectrify America stations charge. But let’s say it’s comparable to a Tesla Supercharger. My guess based on my experience and considering the bigger battery in the truck, probably around 45 to 50 bucks...ish...if it it was empty. Probably around 15 bucks if charging at home....or at least here in BC. Our car is around 8 or 9 bucks, but the battery is a little over half the size at 82 kWh.
Not an expert. JMHO.
Cheers.

Nuclear fusion reactors have "no where to go but up" also...been that way for decades.
For small aerodynamic passenger cars used for commutting, EV is viable. Not so much for trucks towing large brick shaped trailers.
