EVwire brief: The Tesla Cybercab's numbers are finally public. A 2026 EPA certification filing has surfaced, laying out the two-seat robotaxi's powertrain, weight, and range for the first time.
Details:
Drive: Front-wheel drive (single front motor)
Motor: AC three-phase permanent magnet, 163 kW (219 hp)
Battery: Lithium-ion, 326 volts, around 48 kWh (estimated)
Battery specific energy: 154 Wh/kg
Curb weight: 3,113 lbs (1,412 kg)
GVWR: 3,730 lbs (1,692 kg)
Equivalent all-electric range: 418 miles (673 km)
Highway range: 375 miles (604 km)
Regenerative braking: Front wheels (electrical)
Drivetrain: Single-speed automatic
Tesla watcher Sawyer Merritt shared the update on X:
A couple of specs stand out. The range of the Cybercab listed in the EPA document is well above the roughly 300 miles (483 km) Tesla has cited for the vehicle, though the final EPA rating usually lands notably lower. In a way, long range for the Cybercab is unsurprising as Tesla Vice President of Vehicle Engineering Lars Moravy has stated that the vehicle has achieved 165 Wh per mile, making it the most efficient production EV to date.
The vehicle’s estimated 219 hp is also quite powerful for a car that transports just two people, and which will likely operate well within the speed limit at all times.
The Cybercab is the only Front Wheel Drive Tesla to date
Context:
The numbers come from the EPA's certification paperwork for the 2026 Cybercab, the same filing that handed Tesla a Certificate of Conformity on May 26. That certificate is the federal sign-off confirming a vehicle meets emissions standards, the clearance Tesla needs before it can legally sell the robotaxi in the US. The filing lists an introduction-into-commerce date of May 29.
Tesla ran the certification test on April 20 with about 2,159 miles (3,475 km) on the odometer, and the Cybercab was certified under Federal Tier 3 Bin 0 and California ZEV standards for a useful life of 150,000 miles (241,000 km). At 3,113 lbs (1,412 kg) curb weight against a 3,730-lb (1,692 kg) gross rating, the two-seater has just over 600 lbs (280 kg) of headroom for passengers and cargo.
The front-wheel-drive layout is the real surprise. A single front motor and front-wheel regenerative braking mark a clean break from the rear- and all-wheel-drive setups across the rest of Tesla's lineup, a packaging choice that suits a small, efficiency-first robotaxi.
Certification is one of the last steps before deployment. Tesla has been building out the robotaxi infrastructure to put the Cybercab to work, including a first depot spotted in Irving, Texas. With the federal paperwork now in hand, the gap between the spec sheet and paying passengers gets a little narrower.
