EPA Filings Reveal Tesla Cybercab Specs for the First Time
Tesla Cybercab EPA certification documents confirm a 48 kWh battery, 219-hp front motor, 3,113-pound curb weight, and a May 29 introduction-into-commerce date as Giga Texas production ramps.

Tesla's wedge-shaped robotaxi is finally accumulating paperwork instead of only keynote slides. Electrek dug into EPA certification documents filed in May 2026 and published the Cybercab's core specs for the first time: a 48 kWh lithium-ion pack at 326 volts, a single front-mounted permanent-magnet motor rated at 219 horsepower, and a curb weight of 3,113 pounds.
The filing lists introduction into commerce on May 29, 2026, consistent with production activity at Giga Texas that Tesla executives have described as ramping through an unboxed assembly process. The Cybercab is front-wheel drive, unlike every other Tesla currently sold in the U.S., which reflects packaging and efficiency priorities in a vehicle with no manual controls and no driver to impress.
Range math is where readers need patience. The EPA test cycle produced an unadjusted 418.2-mile combined figure under laboratory conditions. The agency's common 0.7 adjustment factor brings that closer to 293 miles on a window sticker, aligning with Tesla's earlier claim of near 300 miles from a relatively small pack. Efficiency, not brute battery size, is the whole thesis.
Electrek also notes wireless inductive charging as the Cybercab's primary refueling method in Tesla's planning, with traditional charging still expected in some form. That matters for anyone comparing fleet economics, not for your household Model Y purchase next month.
For Asian American and Asian Canadian readers watching autonomy from the sidelines, the Cybercab story is upstream infrastructure. It is not a family car recommendation. It is a data point about how far Tesla thinks it can push lightweight EV efficiency when human comfort is removed from the equation.
Regulatory clearance for autonomous operation remains a separate fight from emissions certification. The Cybercab can be certified as an efficient EV and still nowhere near approved to drive itself commercially in most jurisdictions.
If you are cross-shopping today, keep your spreadsheet on vehicles you can actually buy, insure, and service. If you follow robotaxi economics because your commute city keeps flirting with autonomy pilots, these specs tell you Tesla is optimizing for fleet miles per kWh, not weekend road-trip personality.
