Tesla Reveals Cybercab Specs in New EPA Filings

Technical details for Tesla’s dedicated robotaxi are emerging as public rollout nears. Newly available certification documents provide the first official look at Cybercab specifications.

@SawyerMerritt noted on X that public EPA filings disclose new information about the Cybercab, with the documents pointing to some unexpected design decisions.

Unpacking the Specs

According to the full EPA filings, Tesla’s purpose-built autonomous vehicle features a front-wheel drive configuration, a rare shift from the company’s typical rear-wheel or all-wheel drive setups. The battery pack capacity is approximately 48 kWh at an operating voltage of 326V. The electric motor is rated at 163 kW, equivalent to 219 horsepower.

The paperwork lists a curb weight of 3,113 lbs and a Gross Vehicle Weight Rating of 3,730 lbs, underscoring the focus on keeping mass low for high-utilization, fully autonomous service.

The “Equivalent All-Electric Range” is listed as 418 miles, with 375 miles of highway range. However, these lab values do not directly translate to a real-world EPA label; the final EPA range rating is typically lower and should align with earlier statements of about 300 miles of usable range.

Fleet Deployment Getting Closer

Beyond the specifications, the Cybercab has received an EPA Certificate of Conformity. This certificate verifies that a specific vehicle meets all federal Clean Air Act emission standards before it can be sold or introduced into U.S. commerce.

Tesla officially began mass production of the Cybercab at Gigafactory Texas in late April, and a mix of steering wheel-less Cybercabs and units with steering wheels have been observed leaving the line. Over 150 Cybercabs were spotted at staging lots in Texas over the past couple of days, including just over 100 in the outbound lot at Giga Texas, indicating the company is positioning vehicles for a potential public launch.

Tesla recently self-certified its vehicles as SAE Level 4-compliant in Texas to help clear local regulatory paths. While executives previously mentioned waiting for FSD v15 before any large-scale Robotaxi expansions, EPS certifications for the Cybercab suggest initial commercial integration into existing service areas could begin soon.
