Established players can't produce these numbers for their own EV's so you believe a startup will?

Do people remember how much shit Tesla went through?

I think Rivian will take the startup approach and pack as much density into their battery, even if it means sacrificing a large chunk of their margin. The r1t is supposed to have a weight of 8500 pounds[0], so I can see a 150-200kwh battery being packed in there on the Max pack to achieve that range.

200kwh? that's a disaster then.

200Kwh * 40K = 8Gwh?!

that's unrealistic, battery production is the single most limiting factor for all EV's.

big batteries = low volumes

Yes, it's probably necessary if they wanna get near-400 miles on extended range. Even the F150E with extended range only has a 300 mile EPA with estimates of 170kwh[0], and the r1t doesn't look to be insanely more aerodynamic. It's indeed going to be a disaster, but Amazon wants a foot in the door regardless of how much it costs.

That's the gross vehicle weight rating, which is the max weight of the vehicle including cargo. The R1T has a curb weight of ~7,000lbs[0] with the 135kWh battery. That is still as much as a Dually F-350. The 180kWh option would be heavier still and start eating into the payload capacity.
