Cybercab Could Get a 40kWh Pack and Liquid Silver Paint, Musk Says

Tesla’s Cybercab could run on a 40kWh battery pack and add a liquid silver finish, Elon Musk said Saturday on X, while also explaining why Tesla is winding down Cybertruck production to make room for the robotaxi.

“There are efficiency improvements coming that will allow for a 40kWh Cybercab pack. We will make this in liquid silver, so the colors are not too monotonous,” Musk wrote.

Both details are plans, not specs on cars built today. Musk said the efficiency gains are “coming,” and he did not say when a 40kWh pack would reach production, what those gains are, or what range it would deliver. Tesla has not published a battery capacity for current Cybercab builds.

The post was a reply to an X user who compared a CyberSUV with 120kWh of batteries against a Cybercab robotaxi with 48kWh. That 48kWh number came from the user, not from Tesla, so it should not be read as a confirmed figure for today’s Cybercab.

The color comment matters because Tesla’s own Cybercab photos show the car in gold. Musk’s wording suggests liquid silver would join that look rather than replace it, though he did not say whether other colors are planned or whether riders would ever get a choice.

Musk spent the rest of the post on factory priorities. “The biggest thing most people fail to understand is that there are a very limited number of smart, dedicated people! They can only do so many things,” he wrote.

He added that if Tesla has to keep a complex Cybertruck production line, supply chain and engineering team, “we can’t use those people or factory space and machinery for scaling Cybercab, which is the vehicle that will PROFOUNDLY transform the world of terrestrial transport!”

That is the clearest reason Musk has given so far for ending the truck. Musk has also said Tesla will add a Cybertruck shift to work through orders before the Giga Texas line is dismantled around June or July 2027.

A smaller pack would mean less battery per car, and in a battery-constrained world that is the whole point of the reply Musk was answering. How soon it shows up is the open question.
