IRON
An EV maker's humanoid with a reported 82 degrees of freedom and an early solid-state battery claim.
XPeng is best known as a Chinese EV manufacturer, and IRON reflects the same pattern seen with Tesla: an automaker leveraging manufacturing scale and battery expertise to move into humanoids.
IRON's headline claim is an unusually high 82 reported degrees of freedom and an early solid-state battery pack — genuinely promising on paper, though independent, large-scale validation of solid-state runtime claims across the industry is still limited as of 2026.
