The Tesla Cybercab is coming next year.
With a sub-50-kWh battery pack, Tesla claims it would be able to drive "close to" 300 miles.

The Tesla Cybercab could be the most efficient electric vehicle in the world when it hits the streets sometime next year. That’s what two of the EV maker’s execs alluded to during a brief interview with Sandy Munro that explored some of the robotaxi’s peculiar features.

As a reminder, the Tesla Cybercab is a two-door, two-seater EV that doesn’t have a steering wheel—instead, Tesla claims it will be capable of driving itself and doing double duty as both a personal transport device and a self-driving taxi to bring in revenue for the owner.

It’s Tesla’s smallest car with a roof and it was designed for ultimate efficiency, both on the road and during the manufacturing process. As a result, the EV could have a maximum real-world driving range “close to 300 miles” on a full charge, according to Lars Moravy, Tesla’s vice president of vehicle engineering.

That’s not exactly a record-setting figure, but it’s Cybercab's battery size that impresses. As per Moravy, the Cybercab will have a sub-50-kilowatt-hour battery pack. By comparison, the Model 3 Long Range Rear-Wheel Drive has an estimated usable capacity of 75 kWh.

If true, this would result in a real-world efficiency of 6 miles/kilowatt-hour, which is outstanding. By comparison, the facelifted Model 3, which is one of the most efficient EVs out there, is rated at 4 mi/kWh, while the Lucid Air has an efficiency of 4.3 mi/kWh. In other words, the Tesla Cybercab would be 50% more efficient than the Model 3.

The car’s design and manufacturing techniques help a lot with efficiency. According to Franz Von Holzhausen, Tesla’s Senior Design Executive, the teardrop shape of the car has a big impact on reducing energy consumption. Keeping it light also plays a significant role.

While the two execs did not disclose the weight of the two-door EV, they said that its body is made from unpainted polyurethane panels. The color is added to the panels during the manufacturing process, so even if a panel is scratched, there is no base coat that will show up, making scuffs less visible.

In fact, there is very little paint on the car, which leads to lower manufacturing costs and potentially lower repair costs if something goes wrong.

The two execs reiterated that the Tesla Cybercab is on track for a 2026 commercial launch. Manufacturing equipment is currently being installed at the Texas Gigafactory and the first pre-production units are expected to roll off the assembly line this summer.
