Tesla Cybercab EPA Certification Reveals Battery, Range and Robotaxi Specifications

Tesla has taken another step toward commercial deployment of its Cybercab robotaxi after securing EPA certification for the production version of the vehicle. Although limited production had already started at Gigafactory Texas, the newly approved certification provides additional regulatory clearance for future deployment in the U.S. market. EPA documentation also discloses several technical specifications of the two-seat autonomous electric vehicle, offering deeper insight into its powertrain, battery system, vehicle weight, and driving range characteristics.

Tesla Cybercab Powertrain and Electrical Architecture

The Cybercab is classified under the LDV/Passenger Car category and utilizes a front-wheel-drive configuration. Propulsion is provided by a single AC permanent magnet electric motor delivering 163 kW (219 hp). The vehicle employs a single-speed automatic transmission and incorporates regenerative braking functionality on the front wheels to improve energy recovery during deceleration.

The robotaxi operates on a 326-volt electrical architecture and is equipped with a 47.6 kWh lithium-ion battery pack. According to the EPA certification data, the battery offers a specific energy of 154 Wh/kg and weighs approximately 680 lbs. Recharge energy measured from an AC wall source is listed at 53.365 kWh, providing additional insight into the vehicle’s charging requirements and energy consumption profile.

Tesla Cybercab Weight and Payload Capacity

EPA filings indicate that the Cybercab has a curb weight of 3,113 lbs and a Gross Vehicle Weight Rating (GVWR) of 3,730 lbs. This results in a payload capacity of approximately 617 lbs, allowing the vehicle to accommodate two occupants along with their luggage. The payload rating aligns with the Cybercab’s intended purpose as a dedicated autonomous transportation platform designed for passenger mobility services.

EPA Range Performance Data

Range figures published in the certification documents are based on unadjusted EPA Multi-Cycle Test (MCT) results. The Cybercab achieved an unadjusted combined driving range rating of 418.2 miles and an unadjusted highway range rating of 375.4 miles.

The EPA typically applies a correction factor of approximately 0.7 to electric vehicle test results to better reflect real-world driving conditions. Using this methodology, the Cybercab's estimated adjusted combined range would be about 293 miles, while the adjusted highway range would be approximately 263 miles. These figures provide a more practical indication of expected operational performance for future robotaxi service applications.

Production Progress and Deployment Outlook

With EPA certification now secured, the Cybercab moves closer to large-scale deployment in the United States. The vehicle combines a relatively compact battery pack with substantial range performance and a lightweight two-passenger design tailored for autonomous ride-hailing operations. As production activities continue at Gigafactory Texas, the certification details provide a clearer picture of the hardware configuration that will support Tesla’s future robotaxi ambitions.

Frequently Asked Questions

What battery does the Tesla Cybercab use?
The Tesla Cybercab uses a 47.6 kWh lithium-ion battery pack operating on a 326-volt electrical architecture. EPA certification documents indicate the battery has a specific energy rating of 154 Wh/kg and weighs approximately 680 lbs. The pack supports the vehicle’s front-wheel-drive electric powertrain and is designed to provide sufficient energy for autonomous transportation operations while maintaining a relatively lightweight vehicle configuration.

What is the estimated driving range of the Tesla Cybercab?
The Tesla Cybercab achieved an unadjusted EPA combined range rating of 418.2 miles during Multi-Cycle Testing. After applying the EPA’s typical correction factor used to estimate real-world performance, the adjusted combined range is approximately 293 miles. The adjusted highway range is estimated at around 263 miles. These figures provide a more realistic expectation of operational range under everyday driving conditions and potential robotaxi service usage.
