Tesla’s Cybercab just set a new benchmark for electric vehicle efficiency, and it did so without a steering wheel or pedals. The autonomous two-seater, now rolling off the line at Giga Texas, has been certified at 165 Wh/mi, a figure that makes every other production EV on the road look like it’s wasting electricity.

That translates to roughly 6 miles per kWh. Previous efficiency leaders like the Lucid Air and Tesla’s own Model 3 consume approximately 28-40% more energy per mile.

What the numbers actually mean

Lars Moravy, Tesla’s VP of Vehicle Engineering, called the Cybercab “the most efficient EV that has ever been certified and built.” The 165 Wh/mi rating is a certified figure, not a lab estimate.

Moravy also referred to that number as “the starting point.” Tesla’s engineering teams are apparently still chasing further gains, which suggests the production version shipping to fleet operators could eventually get even stingier with its energy consumption.
