Tesla Cybercab EPA Specs Confirmed: 48 kWh Battery, 219 HP and 418-Mile Unadjusted Range

EPA registration documents published on 15 June 2026 confirmed the full technical specifications of the Tesla Cybercab, the company's autonomous two-seat robotaxi. The battery pack is rated at 47.6 kWh, and a single front-mounted motor produces 163 kW (219 hp). The vehicle's kerb weight of 3,113 pounds (1,412 kg) makes it the lightest passenger electric vehicle on the US market and contributes to an energy consumption of approximately 165 Wh per mile — a record for a production EV. The raw EPA multi-cycle test returned a preliminary unadjusted range of 418 miles; the adjusted real-world figure is expected to settle at around 293 miles (470 km). The Cybercab has no steering wheel and is designed for SAE Level 4 autonomous operation. Tesla CEO Elon Musk confirmed during the Q1 2026 earnings call that production at Giga Texas had officially started, calling the initial output "very slow" but forecasting an exponential acceleration toward the end of 2026. The EPA filing lists 29 May 2026 as the introduction-into-commerce date. NHTSA has capped the initial fleet at 2,500 vehicles pending approval of Tesla's unsupervised autonomous driving system.
