Tesla's upcoming Cybercab "has been certified at 165 Wh/mi," [1]reports Electrek — which makes it "the most efficient electric vehicle ever produced — by a wide margin."
> The next most efficient EV on the market, the Lucid Air Pure, consumes 28% more energy per mile. Tesla VP of Vehicle Engineering Lars Moravy confirmed the figure, which represents a certified rating — not a marketing claim or internal target.
>
> It's an impressive achievement, but it comes with a massive asterisk: Tesla accomplished this by building a tiny two-seat robotaxi with no steering wheel, no pedals, and a sub-50 kWh battery pack... Even Tesla's own Model 3 — one of the most efficient passenger EVs you can buy — needs nearly a third more energy to cover the same distance... Where the 165 Wh/mi figure genuinely matters is in the economics of running a robotaxi fleet. Energy cost per mile is one of the biggest operating expenses for any ride-hailing service, and the Cybercab's efficiency gives Tesla a structural cost advantage over competitors...
>
> The small battery pack also means faster charging times and lower per-vehicle battery costs — both critical for fleet economics. Tesla has said the Cybercab [2]will cost $30,000 , and the efficient powertrain is a big part of hitting that price target. Tesla [3]confirmed Cybercab production has started at Giga Texas in April, though the ramp is expected to be slow initially. The company still hasn't solved unsupervised autonomous driving — the [4]first steering wheel-less unit rolled off the line in February, but Tesla's supervised robotaxi fleet currently crashes at roughly four times the rate of human drivers.
