Cybercab gets a 24/7 timeline, plus a drive motor with no rare earths
Tesla has for the first time put a timeline on 24-hour, round-the-clock operation of the Cybercab: AI head Elluswamy said 'next month', on condition that the FSD v15 technical merge is completed.

Musk also confirmed that the Cybercab drive motor contains no rare earths at all (neodymium, dysprosium or terbium) and still delivers 293 miles of range, saving about $1,000 a unit. One is an operating milestone (daily utilisation per vehicle) and the other is a structural de-risking of the supply chain.
Key evidence
- Elluswamy said on X that the Cybercab should run 24 hours a day around next month, once the next technical merge of FSD v15 is completed (the first timetable for night-time Robotaxi service).
- The Robotaxi fleet currently operates 7 days a week in 6 cities (Austin, Dallas, Houston, Miami, Orlando and Tampa), but only from 6am to 10pm, and sits idle at night.
- This follows the unveiling on 3 Sep, paid rides on 4 Sep, the NHTSA case on 5 Sep and the deleted production-guidance wording on 6 Sep. Today adds the first specific, quantifiable milestone on the operating side.
- FSD v15 is described internally as an 'architecture-level leap', with about 10 times the parameters of the current version. v15 will not reach consumer cars until late 2026 to early 2027.
- The Cybercab drive motor contains no rare earths at all (neodymium, dysprosium or terbium) and keeps range at about 293 miles. The motor is 18% smaller and 25% lighter than the previous generation.
- The estimated saving is about $1,000 per drive unit. Tesla has not disclosed the replacement material, and industry analysis points to ferrite or alnico magnets.
- China controls about 90% of global rare earth processing, and Musk himself named it as one of 2 Chinese chokepoints. Each unit uses about 1 kg of rare earths, so production of 1 million units a year makes it a hard constraint.
Catalysts to watch
- The next technical merge of FSD v15 (Elluswamy said 'next month'): if completed on time, it triggers 24/7 Cybercab operation
- Daily utilisation per Cybercab rising from a 16-hour day shift to 24 hours, which directly determines Robotaxi unit economics
- If the rare-earth-free motor is extended from the Cybercab to the core Model 3 and Model Y, it would sharply cut exposure to Chinese rare earths
- A structural supply-chain positive from going rare-earth-free, given exposure at a production rate of 1 million units a year
Risks
- 'Next month' is a verbal target, not a launch, and the FSD v15 schedule has been pushed back again and again.
- Going from 6am-10pm to 24 hours extends operating hours but does not mean the fleet is scaling up.
- Each time the v15 merge slips, the 24/7 timeline drifts with it.
- Tesla has not disclosed the replacement magnets. Ferrite is weaker and bulkier, and alnico tends to overheat under high load, so production yield and consistency of performance are yet to be proven.
- Electrek itself calls it 'a big deal, but not that big', since a saving of $1,000 a unit is a limited share of total vehicle cost.
- The rare-earth-free motor is still used in the Cybercab only, and whether it will spread to the core models has not been decided.
