Tesla has quietly killed off the $16,000 Range Extender for the Cybertruck. The automaker removed it from the Cybertruck configurator last month, signaling the possible demise. Owners who bet big on range problems being temporary will now have no short-term solution. Well that didn't take long. Just weeks after dropping the Tesla Cybertruck's Range Extender from the vehicle's online configurator, Tesla has quietly killed off the accessory completely without delivering a single unit of the $16,000 battery to its customers. An email went out to Cybertruck owners last night, informing them that the company is no longer planning to offer the feature and that their deposit will be refunded in full. The accessory—essentially a large, secondary battery pack for boosting range—had been delayed time and time again since it was first announced. This led to onlookers claiming that the accessory was just vaporware and would never be delivered. Well, it turns out that these conspiracy theories were right, as Tesla announced to reservation holders on Wednesday that it wouldn't be delivering the Range Extender and would be refunding deposits in full. If you recall, when the Cybertruck was first announced, Tesla promised a whopping 500 miles of range thanks to its revolutionary 4680 battery cells. But Tesla continued to run into issues developing the 4680 and failed to deliver on its range promises for the Cybertruck. Instead, it launched with a maximum range of just 340 miles (later revised to 325 miles) and recently released a Long Range variant capable of hitting 350 miles. To make up for the lack of range, Tesla decided to launch a Range Extender for the Cybertruck to get close to its range goal. The $16,000 battery pack would allow owners to reach 470 miles of range once it was installed, and it would only take up a third of the usable bed space (ouch). The Range Extender was delayed again in late 2024, but this time, it would only enable the truck to hit 445 miles of range. No change in the price, though. Either way, Tesla told the public to expect a mid-2025 launch. And then we reach today, where Tesla is officially shrugging its shoulders and giving up on the Range Extender altogether.
