If you rented the Rivian, wait until a cold winter day and drive it and let us know how it performs.
I would welcome an electric car once the problems with it are ironed out (i.e. infrastructure, broken charging stations at irregular intervals, battery fires, cold weather performance, charge times, etc.) Mr. Fusion would be nice.
When I lived in Klamath Falls, Oregon, the 4 seasons were winter, June, July, & August.
Once we had 4 inches of snow in late May nearly froze for the first 1/2 of June.
They claimed the area had 330 days of sunshine, but left out that 300 of those were below freezing.
Folks should check out the news about the horrific bus crash last night in Venice, Italy.
No confirmation of how if was fueled/powered.
“Your math is incorrect.”
You are correct. I basically did what you did. So it’s 1119 amps. Come to think of it, I may have considered that there are two motors. Then each motor would be gobbling only about 500 amps, but even with that my result was wrong. I also might have used 460 volts which is the Rivian battery’s actual value. Still I’m wrong.
When you push the accelerator the power comes on smoothly and silently. Must be some beefy control components in there. Pulse width modulation? No audible sign of that.
It could even have a motor on each wheel, dropping the amperage for each motor even further. Makes more sense than a single motor drawing 1100 amps.
Rivian has a model with 2 motors and a model with 4 motors.
When I looked up EV battery voltages, I saw that there’s the 400-volt standard and a newer 800 volt standard. The big benefit of the 800 volts is faster charging time. That would indeed be a biggie.
Rivian’s 450 volt battery has about 7000 cells. Guess an 800-volt model would have about 14,000 cells. There’s a youtube video on a Rivian teardown.
There was an article about repairing the rear bumper on a Rivian pickup. The insurance company gave the guy $2,400 or something to fix it. Rivian said it would cost $47,000 or something!
The rear bumper is all one piece with both rear panels and the roof of the cab! Rivian said the entire piece needed to be replaced!! (The entire truck was something like $85,000.)
If the whole sector wasn’t still in the silly stages, diesel oil burning battery and cabin heaters would be common in electric vehicles.

“Rivian said it would cost $47,000 or something!”
The essence of why I’m not buying an EV yet if ever.
