Tesla Cybercab certified at 165 Wh/mile, 31% more efficient than Model 3

XFreeze · x · 2026-09-03

Tesla's Cybercab has been certified at just 165 Wh/mile, needing only 16.5 kWh per 100 miles — about 28% less energy than the Lucid Air Pure (23 kWh) and roughly 31% less than the already-efficient Tesla Model 3 Standard (24 kWh).

Per kWh, Cybercab travels 6.1 miles vs 4.35 for the Lucid Air Pure and 4.2 for the Model 3. The efficiency matters even more for a robotaxi: the average US vehicle drives 11,000 miles a year, and Cybercab is designed to spend its life driving, so every saved watt means lower electricity costs, less charging, and smaller battery capacity. Tesla essentially designed the whole car around one question: how efficiently can you move a human from A to B?
