Tesla Robotaxi Details Revealed in EPA FilingsTeslaTesla, and its "technoking"-slash-newly-minted-trillionaire Elon Musk, has spent years promising that a world of driver-less cars was just around the corner. That's why the most interesting thing in newly surfaced documents filed with the U.S. government related to the Cybercab isn't anything related to autonomy; it's that this little car actually sounds like it could be really fun to drive if it happened to have a steering wheel.Our colleagues at Car and Driver were first to draw broader attention to the filings, which include Tesla's Environmental Protection Agency (EPA) Certificate of Conformity and certification documents for the upcoming two-seat Cybercab. While the paperwork leaves plenty of questions unanswered about the vehicle's autonomous ambitions, it provides the clearest look yet at the machine underneath the hype. And the numbers are intriguing.TeslaAccording to the EPA documents, the 2026 Cybercab uses a single electric motor producing 219 horsepower. The vehicle is listed as front-wheel drive with a single-speed transmission. That doesn't sound particularly exciting, but then you get to the weight: 3113 pounds. For context, that's hundreds of pounds lighter than a Hyundai Ioniq 5 and nearly 1500 pounds lighter than a Model S Plaid. In an era when EVs routinely approach or exceed 5000 pounds, the Cybercab looks refreshingly light.AdvertisementAdvertisementThe battery appears relatively modest, too. EPA test data shows a recharge energy figure of 53.365 kWh, suggesting Tesla is relying on a battery pack of roughly 50 kWh rather than the massive packs found in many modern EVs. That's significant because it hints at a different philosophy; instead of using a giant battery to achieve acceptable range, Tesla appears to have focused on reducing weight and maximizing efficiency.TeslaThe EPA test cycle data indicate an equivalent all-electric range of more than 400 miles before EPA adjustment formulas are applied. That doesn't mean buyers—were there to ever be any—could expect a 400-mile EPA sticker; once adjusted using EPA five-cycle methodology, estimates from the testing data point toward something closer to the high-200-mile range, roughly inline with the 280-ish-mile figure first reported elsewhere.TeslaThere are still a few mysteries buried in the paperwork. The certification documents repeatedly identify the Cybercab as a front-wheel-drive vehicle, yet another section lists "drive mode while testing" as all-wheel drive. Given that regenerative braking is also listed as occurring through the front wheels, the AWD reference may simply be a testing anomaly or administrative error rather than evidence of a dual-motor configuration. And the paperwork doesn't clarify whether the production Cybercab will include a steering wheel and pedals. Tesla's original vision famously called for neither ... but after seeing the specs, we can't help thinking that might be a missed opportunity.You Might Also LikeIf You Can Only Own One Car, Make It One of TheseThese Are the Most Popular Cars by State
