[DigitalToday Yu Seung-a] Tesla’s two-door robotaxi, the Cybercab, disclosed key specifications including battery capacity, output and weight through documents submitted to the U.S. Environmental Protection Agency (EPA).

InsideEVs, an electric vehicle media outlet, reported on June 15 local time that the Cybercab has a 48 kWh battery, output equivalent to 219 horsepower and a curb weight of 3,113 pounds, or about 1,400 kg.

The filing is interpreted as a sign that preparations for mass production of the Cybercab have advanced by a step. Tesla submitted paperwork required for production-vehicle certification. The process also confirmed official weight, output, battery information and test driving-range figures.

The most striking point is weight. The Cybercab’s curb weight is 3,113 pounds, or about 1,400 kg, about 700 pounds, or about 320 kg, lighter than the lightest trim of the Tesla Model 3. It is assessed as among the lightest EVs sold in the U.S. market. Given that EVs are generally heavier than internal combustion vehicles, the figure shows a design direction focused on weight reduction.

Gross vehicle weight is listed as 3,730 pounds, or about 1,700 kg. That implies a payload capacity, including passengers and cargo, of about 617 pounds, or about 280 kg. The absolute payload capacity is not large, but it is interpreted as a configuration reflecting the characteristics of a two-door vehicle.

The powertrain uses a single permanent-magnet motor mounted at the front. The document lists peak output at 163 kilowatts (kW), which converts to about 219 horsepower. The Cybercab was initially unveiled as a self-driving taxi operating without a steering wheel and pedals, but test vehicles were later fitted with both. The form of the actual mass-production model has not yet been decided.

The battery is confirmed at 146 Ah and 326 V. Energy capacity calculated on that basis is 47,596 Wh, or about 48 kWh. By battery capacity alone, it is smaller than a midsize electric car, but it appears to reflect a design aimed at boosting efficiency by combining it with low vehicle weight.

The driving range is not yet a final certified figure. Test documents list a combined driving range of 418.226 miles, or about 670 km, but that is a figure calculated in a laboratory environment. The EPA applies a separate adjustment process to calculate a range for actual display. According to an EPA explanatory note, "the most common method is to apply a factor of 0.7 to all test numbers including driving range."

Applying that standard puts the Cybercab’s expected range at about 293 miles, or about 470 km.

That broadly aligns with the direction Tesla has presented. Tesla executives have previously mentioned that the Cybercab "will have a range close to 300 miles (about 480 km)." But since the currently confirmed figure is preliminary, differences from the final certification result remain possible.

The remaining variables are the launch timing and price. Tesla said Cybercab production has already begun but did not disclose specific production volume. The last target the company presented was a launch before 2027 and a price below $30,000 (about 45.5 million won). But full self-driving software, a core of the robotaxi business, is currently being tested only in some cities.

As a result, the Cybercab is stepping up preparations for mass production on the hardware side, but whether it is commercialised is likely to depend on the scope of self-driving technology implementation and the launch schedule. The EPA filing has confirmed many key specifications, but the actual sales timing and final price have not yet been decided.
