In January, Tesla announced plans to stop production of its high-end Model S and X vehicles, choosing to turn that manufacturing capacity in Fremont, California, into a line dedicated to humanoid robot production. Car production stopped in May. Tesla is delivering its final “Signature” versions of the S and X this month. Three axial flux motors are capable of delivering 1,153 horsepower and are also capable of going from zero to 60 miles per hour in about two seconds.
