EPA Certifies Tesla Cybercab and Publishes Full Technical Specifications

Paperwork confirms an ultra-efficient two-seat robotaxi lacking regulatory approval for unsupervised driverless operation.

Overview

  • EPA documents publicly disclose the Cybercab’s engineering: a front-mounted 163 kW (219 hp) permanent-magnet motor, a 326 V 146 Ah battery (about 47.6–48 kWh), and a curb weight of 3,113 lbs.
  • Raw EPA lab tests list unadjusted ranges of 418.2 miles combined and 375.4 miles highway, which translate to roughly 280–300 miles after standard real-world adjustment factors.
  • The filing certifies the Cybercab as a battery-electric Zero Emission Vehicle and establishes an 'Introduction into Commerce Date' of May 29, 2026, per EPA records filed May 21 and certified May 26, 2026.
  • Tesla has started production at Giga Texas and staged units for ramp-up, but the Cybercab’s purpose as a driverless robotaxi depends on separate regulatory permission for unsupervised operation that the EPA certificate does not provide.
  • The vehicle’s two-seat, steer-by-wire design, inductive charging and 165 Wh/mi efficiency show Tesla optimized cost and energy use for robotaxi economics, and competitors with LiDAR-heavy systems remain operationally ahead in approved driverless services.
