Elon Musk posted on X on Nov. 7 that “there are efficiency improvements coming that will allow for a 40kWh Cybercab pack” and that Tesla “will make this in liquid silver, so the colors are not too monotonous,” Teslarati reported.

In the same post Musk said keeping the Cybertruck line would tie up people and factory space needed to scale Cybercab, following the Cybertruck wind-down announcement.
