Cybercab certified at 165 Wh/mi efficiency

Tesla’s Cybercab has been reported at 165 watt-hours per mile, a figure that would put the two-seat robotaxi at the top of the EV efficiency rankings if it holds through broader public documentation. Electrek reported the number on May 22 and said Tesla Vice President of Vehicle Engineering Lars Moravy described it as a certified rating rather than an internal target. Other Tesla-focused outlets published similar accounts after a May 20 Tesla event in Fremont, California. The number matters because efficiency shapes battery size, operating cost and, in Tesla’s case, the economics of a planned robotaxi fleet. ### Where did the 165 Wh/mi figure come from? Electrek reported on May 22 that Moravy gave the number during Tesla’s Model S and Model X Signature Delivery event. Drive Tesla Canada and Not a Tesla App also said Moravy presented the Cybercab at 165 Wh/mi and characterized it as a certified figure. None of those reports, in the material available online, linked to an EPA label or a standalone regulatory filing, so the current public trail runs through Tesla’s onstage comments and outlet write-ups of them. (electrek.co) The wording matters. Electrek said Moravy framed the result as “certified,” which would distinguish it from an engineering target or promotional estimate. Reuters could not independently verify a regulator-hosted certification page from the search results reviewed here, and Tesla did not immediately provide additional public documentation in the sources examined. (electrek.co) ### How far ahead of other EVs would that put Cybercab? Electrek said the next most efficient EV it cited was the Lucid Air Pure at 230 Wh/mi, with Tesla Model 3 rear-wheel-drive and Model Y rear-wheel-drive variants around 240 Wh/mi. On that comparison, 165 Wh/mi would represent a large gap versus current mainstream EV benchmarks. That comparison comes with caveats built into the vehicle itself. (electrek.co) Electrek said the Cybercab is a small two-seat vehicle with no steering wheel or pedals and a battery pack below 50 kWh, while Notebookcheck, citing Tesla disclosures, reported a sub-50 kWh pack and about 300 miles of real-world range. A smaller body, fewer controls and a lighter platform would all tend to help efficiency, though Tesla has not published a full consumer specification sheet in the sources reviewed. ### Why is Tesla emphasizing efficiency instead of just range? Tesla has tied Cybercab to robotaxi service, where cost per mile matters as much as headline range. Electrek said energy cost per mile is one of the biggest operating expenses in ride-hailing, and a lower Wh/mi figure would reduce electricity use across a fleet. That is one reason efficiency can matter more for a dedicated autonomous vehicle than for a conventional consumer car. (electrek.co) Basenor reported that Tesla launched commercial robotaxi service in Houston and Dallas on April 18 using Model Y vehicles in geofenced operating areas, while a separate Basenor report said Tesla-prepared vehicles were spotted in Florida ahead of a possible Orlando-area launch. Those reports are not official Tesla announcements in the sources reviewed, but they show why Cybercab metrics are being read alongside rollout signals for Tesla’s autonomous service plans. (electrek.co) ### What still is not public? An EPA window sticker, a full certification database entry and a detailed breakdown of test conditions were not visible in the search results reviewed for this story. Without those documents, it is not yet possible to compare the Cybercab number line-by-line with every certified EV under identical public paperwork. (basenor.com) Tesla’s next concrete step is broader publication of Cybercab specifications and certification records as the vehicle moves closer to deployment. The company has already begun using the Cybercab in public presentations, and the May 20 Fremont event where Moravy cited the 165 Wh/mi figure is the clearest named milestone attached to the number so far.
