Tesla unveils some secrets of its Cybercab
- Published on 15/09/2026 7:18
The two-seater robotaxi from Tesla reveals a technical specification that prioritizes lightness and aerodynamics, with some precautions regarding the range figures.
No steering wheel, no pedals, but a mechanism that is now less mysterious. The Tesla Cybercab relies on a simple architecture: an electric motor with permanent magnets driving the front wheels. The file submitted to the U.S. EPA indicates a power of 163 kW, or about 222 hp, with a curb weight of 1,412 kg. These characteristics are more than sufficient to transport two passengers.
A battery of about 48 kWh
The lithium-ion accumulator shows a voltage of 326 volts and a capacity of 146 Ah. Their multiplication results in a nominal energy of about 47.6 kWh, without prejudging the actually usable capacity. Thus, Tesla avoids the overconsumption of large, heavy, and expensive batteries.
However, caution is advised regarding the range: the 418 miles, or about 673 km, mentioned in the file correspond to a laboratory measurement before correction. Presenting them as EPA-certified range would be misleading. This result does not constitute a relevant WLTP value applicable in Europe either.
Aerodynamics in service of economy
During its presentation in Austin, Tesla announced a drag coefficient of less than 0.20. This streamlined silhouette should limit the energy required for forward movement, especially as speed increases. The choice of two seats also responds to a usage logic: according to the manufacturer, over 80% of rides involve at most two people.
The large gullwing doors facilitate access to a cabin that automatically customizes temperature, seat position, and multimedia accounts. Braille indications complete this equipment.
Finally, the “Unboxed” industrial method separately assembles several modules. Tesla announces a production line reduced by half and injection-molded exterior panels, incorporating recycled materials, without a conventional paint shop. The technical objective is clear: save as much in manufacturing as in each journey. Source: presentation reported by Drive Tesla
