Tesla Cybercab certified at 165 Wh/mi

Tesla’s Cybercab has been certified at 165 watt-hours per mile, a figure Electrek reported on May 22 from certification data and described as the lowest energy-use rating for an electric vehicle on the market. The vehicle is a two-seat, purpose-built robotaxi with no driver controls, a layout Tesla has pitched as central to its autonomous fleet strategy. Electrek said the rating was confirmed by Tesla Vice President of Vehicle Engineering Lars Moravy and framed it as a certified number rather than an internal target. ### How low is 165 Wh/mi in practical terms? Electrek compared the Cybercab’s 165 Wh/mi figure with several current EVs and said the gap was wide. The Lucid Air Pure rear-wheel-drive version on 19-inch wheels came in at 230 Wh/mi, while Tesla’s Model 3 RWD on 18-inch wheels and Model Y RWD on 18-inch wheels were both listed at 240 Wh/mi. Hyundai’s Ioniq 6 SE RWD was listed at 241 Wh/mi. (electrek.co) That means the Cybercab uses about 28% less energy per mile than the Lucid Air Pure, based on Electrek’s comparison. Electrek also said the Model 3 needs nearly a third more energy to cover the same distance. ### Why is the Cybercab’s number so different from other EVs? Electrek attributed much of the result to the Cybercab’s stripped-down form factor. (electrek.co) The outlet described the vehicle as a “purpose-built, two-seat autonomous pod” with no steering wheel or pedals, and said that makes comparisons with conventional passenger EVs imperfect. The design matters because the Cybercab is not being sold as a typical family sedan or crossover. Tesla has presented it as a dedicated robotaxi, and Electrek said that narrower use case helps explain why the vehicle can post a much lower consumption figure than larger, more versatile EVs. That is Electrek’s characterization of the trade-off, not a statement Tesla made in the cited report. (electrek.co) ### Does this settle the question of real-world efficiency? The 165 Wh/mi figure is a certification result, not a broad set of public road-test data. Electrek explicitly presented it as a certified efficiency rating, which makes it useful for comparing vehicles on the same official basis, but it does not by itself answer how the Cybercab will perform across different routes, speeds, weather conditions and payloads. (electrek.co) FuelEconomy.gov’s public site shows EPA fuel-economy listings for Tesla vehicles generally, though the Cybercab page was not directly accessible through search results reviewed here. That means the reported 165 Wh/mi figure is best treated, for now, as a reported certification datapoint cited by Electrek and repeated by other Tesla-focused outlets. ### Where does this fit in Tesla’s broader Cybercab rollout? (electrek.co) Electrek reported on April 23 that Cybercab production had officially started at Gigafactory Texas, citing Tesla CEO Elon Musk on the company’s first-quarter 2026 earnings call. In the same report, Electrek said Lars Moravy had described the vehicle as moving through standard self-certification rather than relying on a special NHTSA exemption capped at 2,500 vehicles annually. (fueleconomy.gov) Electrek also reported on Feb. 17 that Tesla had rolled the first steering-wheel-less Cybercab unit off the line at Gigafactory Texas. The latest efficiency number adds another concrete specification to a vehicle Tesla has so far discussed mostly through production updates and autonomy plans. (electrek.co) ### What should readers watch next? Tesla’s next public milestones on the Cybercab are likely to come through company events, regulatory listings and earnings commentary. Electrek’s April 23 report said production had begun, and its May 22 report added the 165 Wh/mi certification figure; the next step for outside verification will be broader publication of official efficiency and range data tied to the vehicle’s launch.
