Musk: Cybercab to get 40kWh battery, new Liquid Silver paint

KEY FACTS

Musk said on X that Tesla will further refine the Cybercab to improve energy efficiency.
The revised Cybercab will use a 40kWh battery pack, down from 48kWh in the current production model.
Tesla will also add a Liquid Silver body color to the Cybercab.
This week Tesla announced it is canceling the Cybertruck line at its Texas factory to free up capacity for Cybercab production.
Musk said keeping the Cybertruck line would tie up manpower, factory space and equipment, hampering Cybercab production ramp-up.

PHYSIX OBSERVATION

Running the same operating mileage on a smaller battery shows Tesla is betting cost reduction on energy efficiency rather than piling on capacity, a real per-kilometer cost win for Robotaxi. Killing Cybertruck to free capacity is a clear signal: Tesla's resources are shifting from selling cars to selling mobility services, and no amount of controversy will make it turn back.
