Tesla has confirmed it has given up on plans to make a Cybertruck range extender to achieve the range it originally promised on the electric pickup truck.
It started refunding deposits for the $16,000 extra battery pack.
When Tesla unveiled the production version of the Cybertruck in late 2023, two main disappointments were the price and the range.
The tri-motor version, the most popular in reservation tallies before production, was supposed to have over 500 miles of range and start at $70,000.
Tesla now sells the tri-motor Cybertruck for $100,000 and only has a range of 320 miles.
The dual-motor Cybertruck was supposed to cost $50,000 and have over 300 miles of range. In reality, it starts at $80,000 and has 325 miles of range.

How do you figure dual front motors would alleviate any of what you said a front diff would need? Dual front motors will still be rigidly mounted to the chassis, requiring flexible couplings. The rear is also independent, requiring the same flexible couplings whether it’s a diff or motors. CV axles all around. Non-steer wheels still have vertical travel from the suspension.
You wouldn’t need a front differential, for one. But you’re right, unless they somehow made a directly wheel coupled motor that turned with the wheel, it l still needs CV couplings.
As for rear, they don’t need CV axles. Two simple cross couplings are enough. The speed variability happens significantly when the wheels turn, going up and down is a negligible issue. Cars have been using the much chapter and simple cross couplings in the rear for decades.
The CT has four-wheel steering, so yeah, it’s actually more complicated than a regular truck in that regard. I remember reading something about the mechanisms to make that possible taking up a shitload of room.
Oh yeah, forgot about that. They had to bolt that on to have any chance of having a reasonable turn radius.
