This is just a stream of consciousness message, so it's a bit messy
I've been thinking more about Cybertruck pack size and how it might be bellow the 200 kWh through some magic although my previous reasoning goes against it
Think about this way, the Semi has a ~950 kWh pack and can go 500 miles with 82k lbs, the RAM can go the same distance with a 229 kWh pack and probably around 10k lbs of total weight., so 1/4 of the battery and 8 times less weight, as someone which I forget and can't find now posted a few pages back
This means that Tesla knows how to pull some tricks (as we know). I've been thinking that with the test cycle EPA provides, it's easy to find which combinations of parameters Cybertruck has to have to reach 500 miles on the EPA test cycle and what pack size each combination requires, just don't know if it's worth diving into it this close to launch
Also, my main way of speculating pack size was comparing current efficiency advantages of Tesla vehicles over the best competitors on each class, but there is so much more room for Tesla to distance itself from others in the truck space, I mean, look at the F150, it's two bricks on top of each other, with a non flat bottom with tons of turbulences and a close to 0.5 drag coefficient, or the RAM and the pack size they need
Rivian did a nice aero job, but their motors are far from efficient, drag coefficient is 0.3 on it, while Elon said they could hit 0.3 on Cybertruck, if Rivian did, Tesla could probably beat it
Another way to look at it, from the latest dimensions, the frontal area of Cybertruck is just 10% bigger than a Model X, but maybe 30% heavier, 20% more consumption than a X to be on the high side? ~170 kWh pack in that case
The downside is, the most efficient it is alone, the bigger the hit it will have when towing, but still, 60% hit when towing give you 200 towing miles for a full pack or 160 towing miles 10-90%, if it chargers fast (sub 30 minutes 10-90%), V4s are trailer friendly and everywhere, doesn't seem like a problem and would be quite a bit better than any other EV
But yet another way to look at it is, from my previous Twitter thread, there likely is room for more than 170 kWh of cells on it, so they might as well use it and beat specs if 4680 ramp is going faster than Cybertruck ramp cell need will be
Can't wait until we have more specs and when people get theirs and start doing all those tests
