double the number of 4680 in a model Y is not gonna cut it for the 500miles cybertruck. the 67kWh 4680 Model Y has 828 cells double the cells would be only so about 81Wh per cell.
If the Cybertruck was as efficient as a model X Plaid on 22in wheels, it would need 160kWh to drive 500miles.
It doesnt take a genius to know that a CT with a drag coeff somewhere beetween 0.3 and 0.4 at best vs 0.24 , one more motor, at least 60kWh more, 4 wheeel steering, 35 in off road tires, 3x the tow rating, 3.5x the payload, powered tailgat, ramp and tonneau cover, armored glass etc will be way heavier and way less efficient than the model X. I think 200kWh is a pretty conservative estimate of the battery capcacity the will need to achieve 500 miles epa range. So actually more like 3x the model Y 4680 capacity or about 2500 cells. Of course they might not make ONLY 500miles versions at launch, but its still very likely that they will first try to deliver the highest trims..
~140kWh / 1600+ 4680 cells seems more reasonable for the 350 miles dual motor version
The RWD '250miles version...who knows if they will ever make one. I don't see any manufacturer making 2WD electric trucks, so...

@rogerstarkey5390 more efficient, yes, Id put my money on it. lightning has the worst electric truck dag coefficient, and model Y more efficient than mach E. much lighter no, at least not in the 500 miles version because even if its it will require a battery close to 200kWh and will be heavier than the R1T.
based on the most efficient electric truck on the marker , 43kWh/100miles means 215kWh/500miles
considering it will have to lug a giant battery around and a less than stellar drag coefficient (way higher than R1T), 200kWh 40kWh/100 miles 84 mpge would actually be an excellent result. hummer EV only does 300miles on same battery size
170kWh would be the same efficiency as the Model X plaid, which absoluely CAN NOT happen with more weight, ground clearance, MUCH higher aero drag, way bigger truck tires
The hopes for cybertruck relatively light weight were based on structural 4680 battery pack which turns out much heavier /kWh than LR 21700 battery in the model Y
And revolutionary Exoskeleton which will be actually on top of a traditional unibody castings, plus all the heavy equipments (4 motors, 4 wheel steering, heavy glass and panels)
