That's about 35kWh/100km. For comparison, "normal" electric cars need something between 15 and 20kWh/100km.

I had to do the conversion, 15k-20kWh/100km ~ 250-330Wh/mi.

My Focus EV 2017 has a lifetime of about 275Wh/mi (and I have a lead foot).

The difference being one of those numbers is actually real.

Any idea what efficiency of "normal" trucks are; F150/Rivian/etc? Or even electric SUV; Model X, Rav4 Prime, etc?

Hey, you only need about 200 200W solar panels to charge this during a typical clear day. You could build a farm like that on a Texas ranch and be a true 100% self-reliant individualist and drive a Hummer.

A 200KWh battery could also power a large (e.g. 4br+) house for at least a few days.

You can only power a house if the car is setup to be able to push power back to the grid. sadly teslas are not. Did the hummer launch announce such capability?

I don't know, but they should have an option where it can have 200 200W thin film panels in the back that can unfold. That would make it the green solar renewable version of the Canyonero from the Simpsons.

the transition to EVs will only increase driving and efficiency will be far down on the list as many will chime in that it does not matter because its not oil and further enforce their view by pointing to solar and wind energy.

it is very much the same scenario that played out with the move to LED lighting, suddenly you can so much more lighting because it cost so little compared to previous lighting.

if anything our next bogeyman may be all the excess heat we generate by increased power usage

This isn't scheduled to be out until the end of next year. Is it possible they are saving themselves future PR by announcing improvements before its release?

But other EVs also improve in that time so kinda irrelevant. And just by the look of it it aerodynamically simply cant compete with a car and no one should expect that.
