SOURCE GROUNDING & ENGINEERING CONTEXT
“The Cybercab motor uses no rare earth metals, but maintains the same range! This was extremely hard to achieve.” — Elon Musk
“The Cybercab drive unit features a simplified bar-wound stator and lubrication system, plus an overall architecture that enables fully automated, sub-10-second cycle times. It is 18% smaller, 25% lighter and more efficient than other top performing electric vehicle drive units.” — Sawyer Merritt
