Tesla Cybercab Specs: EPA Filing Reveals 48 kWh Battery, 293-Mile Range, 3,113-lb Curb Weight

Tesla is one step closer to putting its Cybercab into production. The company filed official documents with the Environmental Protection Agency that are required for full production approval, and the paperwork-spotted by Car and Driver-reveals the robotaxi's weight, power output, battery capacity, and tested range figures.

Weight and Payload

The Cybercab tips the scales at 3,113 pounds, about 700 pounds lighter than the lightest Tesla Model 3. That puts it in the same weight class as a Honda Civic Touring, which is notable for an electric vehicle. Most EVs are significantly heavier-a Chevrolet Bolt weighs nearly 3,800 pounds.

Its gross vehicle weight rating (GVWR) comes in at 3,730 pounds. Subtract the curb weight and you get a payload capacity of 617 pounds for passengers and cargo. That's on the lower end compared to compact cars (a Civic typically offers 800 to 1,000 pounds), but reasonable for a two-door vehicle. With two passengers and carry-on luggage, the Cybercab stays well under its maximum.

Powertrain

A single front-mounted permanent magnet motor delivers 219 horsepower (163 kW). Tesla originally said the Cybercab would ship without a steering wheel or pedals, banking on full autonomy from day one-a bet that CEO Elon Musk has been making for years. Later test units were fitted with both. Regardless of who is doing the driving, 219 hp should give the little two-door decent punch.

Battery and Range

The battery pack is rated at 146 amp-hours at 326 volts, working out to 47,596 watt-hours-or roughly 48 kWh. Under lab conditions using the EPA test cycle, the Cybercab returned 418.2 miles of calculated range. The EPA requires manufacturers to apply an adjustment factor, typically 0.7, to convert lab results to real-world estimates. Apply that multiplier and you land at approximately 293 miles.

That aligns with what one Tesla executive previously claimed: the Cybercab would have "close to 300 miles of range."

What We Still Don't Know

The EPA filing answers several open questions, but two big ones remain: when will the Cybercab actually go on sale, and what will it cost? Tesla has a history of optimistic timelines, and the robotaxi has already been delayed. If the Cybercab does reach production, these specs suggest a lightweight, efficient urban runabout designed more for fleet economics than passenger car conventions.
