Tesla's Cybertruck range extender has faced a setback, with the company delaying its release and downgrading its estimated mileage. The device was initially expected to provide an additional 145 miles of range for the dual-motor version of the truck, but Tesla now estimates it will add only 120 miles. The delay is also notable, with the range extender's availability pushed back from early 2025 to mid-2025. The estimated cost of the device remains $16,000.
