EVwire brief: Tesla plans to make the Cybercab even more efficient, despite the two-seater already being the most efficient production vehicle ever at 6.18 miles per kWh (9.95 km per kWh).
Elon Musk said upcoming efficiency improvements will allow Tesla to fit the Cybercab with a 40 kWh battery pack, which is about 16% smaller than its current 47.6 kWh unit. A smaller pack would also cut weight from a vehicle that already has a curb weight of just 3,113 lbs (1,412 kg). Musk added that the updated Cybercab will be made in liquid silver, so the colors are not too monotonous.
Musk shared the update on X, replying to a thread in which X user Warren Redlich argued that Tesla gets far more gross profit per kWh of battery from a Cybercab in its Robotaxi fleet than from selling a consumer vehicle. Here's Musk's post:

In the same post, Musk explained why the Cybertruck has to make room for the Cybercab. He noted that the number of smart, dedicated people Tesla has is very limited, and that they can only do so many things at once:
If we have to maintain a complex production line, supply chain and allocate engineering for Cybertruck, we can’t use those people or factory space and machinery for scaling Cybercab, which is the vehicle that will PROFOUNDLY transform the world of terrestrial transport!
Prior to Elon Musk’s announcement that the Cybertruck will be discontinued, he noted that Tesla might produce the vehicle as a fully autonomous unit that’s optimized for deliveries. “There's a lot of cargo that needs to move locally within a city, and an autonomous Cybertruck could be very useful for that,” he said.
The current generation Cybercab is equipped with a 47.6 kWh battery pack.

Context:
Musk's comments come just days after he announced that Tesla will wind down Cybertruck production at Gigafactory Texas around the middle of 2027 to make room for more Cybercab production. That announcement came about 80 minutes after Tesla raised US Cybertruck prices by up to 9% and paused new orders for the entry-level Dual-Motor AWD trim. Wes Morrill, the Cybertruck's lead engineer, said at the time that the truck "lives on through Cybercab."
The Cybercab, which is built in the same factory, has been ramping quickly. Tesla now has 573 Cybercabs registered to its Robotaxi fleet in Texas, per Texas Department of Motor Vehicles records. During its Q3 2026 earnings call, Tesla also said Cybercab rides would launch in Dallas this month and that it is targeting its first Cybercab customer deliveries by the end of 2026.
