Tesla has continued to flex the strength, rigidity, and robustness of its all-electric pickup, the Cybertruck. In fact, since 2019, Cybertruck’s ability to avoid dents, dings, and even gunfire has been one of the main selling points Tesla has used to attract buyers who are looking for a vehicle that can handle the most intense challenges.

But that does not mean Tesla is not still actively trying to make it even better.

In a new hardware update, Tesla has decided to change the material of the Cybertruck’s underbody panels from aluminum to carbon fiber, a move that aims to not only increase pricing efficiency but also improve strength.

Cybertruck Lead Engineer Wes Morrill confirmed the change was made to the Cybertruck recently after it was spotted by Coleton Guerin of Out of Spec. This particular trim level was a Cyberbeast, but it is being applied to all trims to keep supply chain efficiency high and have less variance across trim levels.

Morrill said that Tesla tested different materials for the underbody panel protection, and carbon fiber performed better than aluminum, which is what the company was using since its first deliveries in 2023.

Additionally, there are some efficiency improvements because Tesla can better form the areas around the bolts to keep underbody airflow cleaner than previously.

good eye – it’s a new material. Testing showed it to be more durable than the aluminum while being lower weight and cost. Also slight efficiency improvement since we can better form the areas around the bolts to keep the underbody airflow cleaner than what stamped aluminum allows

Carbon fiber is traditionally lighter and more durable than aluminum, which is why it is such a popular material among luxury automakers, and EV makers will utilize some of the materials around battery packs to save weight.

This is the first instance of Tesla utilizing carbon fiber on the Cybertruck’s exterior to help with overall performance and strength. As previously mentioned, Tesla used aluminum to protect the underside of the body, but it is pretty typical for the company to continue making engineering changes that will improve the car in the future.

Tesla is asking a federal court to force a Cybertruck parts supplier to hand back manufacturing equipment the automaker says it owns, warning that production of the pickup could stop within days without it.

The company filed an emergency lawsuit in the U.S. District Court for the Western District of Texas, asking for a hearing on short notice to recover tooling used to stamp Cybertruck components at Giga Texas. According to the complaint, first reported by Bloomberg, the equipment sits inside a Troy, Texas plant run by Angstrom Automotive Group, which bought the facility from Anderton Casting last year and kept it on as a Tesla supplier. Case 6:26-cv-0477 is one of the more urgent supplier disputes Tesla has brought to court.

The dispute traces back to July 13, when Angstrom told Tesla it planned to close the Troy facility. The two sides then failed to agree on a plan to retrieve the die-cast tools, trim dies, fixtures, cutting tools, gauges and X-ray equipment that belong to Tesla. A shipment of 700 finished parts due out on July 17 never left the building, according to the filing. When Tesla sent representatives to the plant on July 21, accompanied by law enforcement, they were turned away.

Tesla’s complaint alleges Angstrom then asked for an extra $250,000 a week to keep the facility running, a demand the automaker calls an attempt to exert commercial pressure by holding its own property “for ransom.” Angstrom has not issued a public response.

The lawsuit states thousands of Cybertrucks already assigned to customers are tied to the parts in question, and that supply will run out “in mere days” without court intervention. Tesla says it is not asking the judge to resolve the underlying contract dispute or award damages, only to get physical access to equipment it already owns.

Tesla has also turned to the courts before to protect its supply chain, including its ongoing trade secret fight with former battery equipment supplier Matthews International, where a judge issued a permanent injunction against the company earlier this year.

A ruling on Tesla’s request for emergency relief is expected within days.

Tesla’s latest 2026 Summer Update quietly closes out one of the more tedious steps in personalizing a Tesla’s digital appearance. Uploading a custom wrap design used to require a USB drive. Now it doesn’t.

The feature is listed in Tesla’s release notes as “Send Custom Wraps from Mobile App.” The company described it plainly: “Skip the USB drive and upload a custom wrap of your car from the mobile app. Instructions for creating a custom wrap here: github.com/teslamotors/custom-wraps.”

The digital wrap tool has been around since Tesla’s 2024 Holiday Update, when it launched for Cybertruck owners first, as Teslarati reported at the time. Getting a design onto the car meant formatting a USB drive, creating a folder named exactly “Wraps,” dropping in PNG files sized between 512×512 and 1024×1024 pixels and under 1 MB each, then plugging the drive in and applying the wrap through Toybox. Tesla expanded the tool to other models and renamed it from “Colorizer” to “Paint Shop” with the 2025 Holiday Update, while also adding license plate and window tint customization alongside the wraps.

The latest Summer Update removes the USB step from that process. Owners will be able to pull a design from wherever they saved it, whether that’s a download from social media or something built from Tesla’s own GitHub templates, and push it to the car directly through the app.

It’s a small fix relative to the rest of this latest release, which also included expanded Grok voice commands, automatic navigation that learns regular routes, and self-driving stats inside the mobile app, all detailed in our rundown of the full Summer Update. The USB requirement was one of the more common complaints about Paint Shop since it launched. Tesla did not say when the wrap upload change would reach individual vehicles, only that the broader update is rolling out now in waves.
