Saw that one, no range posted
Arnold almost drove it on the road

Interesting and I knew it was coming someday soon but, yeah, how far can this go? And what do I do when I'm 90 miles deep into the Canyonlands with low charge? Where's the electric jerry can? How big do the solar panels have to be and how long do I need to set them up for to get out?

I bet EV West would have some insight.

How big do the solar panels have to be and how long do I need to set them up for to get out?

"Efficient" EVs use about 0.25 kWh (kilo watt hour, or 1,000 watts for an hour) per mile. I'd guess that the EV G takes about 0.5kWh or so; but unlike gas engines the use rate won't go up appreciatively at slow speeds and probably not much higher for off road, either. A big 2.5 x 5 foot solar panel is now about 300 watts; with full sun, you might get 1/4 to 1/2 mile additional range for each HOUR it is directly pointed into the sun. 90 miles away from civilization will require 180 - 360 hours of full sun from one panel! If you assume about 6 hours of "full" sun a day, plan on taking a month or two to get home with one panel. This is the reason why no EV manufacturer is touting solar panels for increased range - it is not hardly a drop in the bucket.

Yes - an interesting prototype but with only an 80 kWh battery and the weight and aerodynamics of a G-wagen the range would be about 100 miles or so at highway speeds.

The other overstatement is the battery charger - here is what it says:

"CHARGER: The 22 kW quick charger lets you fully charge the batteries within one hour, using a standard domestic mains socket."

22kW would require about 100 amps @ 240 VAC which is not available from and "standard domestic mains socket" other than from the kWh meter itself - perhaps that is what they meant...

Also - at a charging rate of 22 kW it would take about 4 hours to recharge an 80 kWh battery if it was from a very low state of charge.

Did you see the new Mercedes AA Class?

You need a trailer with a gas generator on it.
