Tesla Quietly Made the Cybertruck Even Stronger
Cybertruck underbody panels now use carbon fiber instead of aluminum for better durability and airflow.
Tesla has quietly upgraded the Cybertruck’s underbody protection, switching from aluminum to carbon fiber panels in a move that improves durability and efficiency.
What Happened
The change was confirmed by Cybertruck Lead Engineer Wes Morrill after it was spotted on a Cyberbeast trim by Coleton Guerin of Out of Spec. The new material is being applied across all trims to keep supply chain variance low, according to Morrill.
Morrill said testing showed carbon fiber to be more durable than the aluminum Tesla had used since first deliveries in 2023, while also being lighter and lower cost. He added there’s a slight efficiency improvement because the areas around bolts can now be better formed to keep underbody airflow cleaner than stamped aluminum allows.
Why It Matters
For owners and buyers, the switch means a stronger, lighter underbody without added weight or cost — and it marks Tesla's first use of carbon fiber on the Cybertruck’s exterior for performance and strength. The move also reflects Tesla's pattern of continuous engineering updates to improve its vehicles over time.
The Bottom Line
With this hardware revision, Tesla is quietly making the already rugged Cybertruck even tougher while trimming weight and cost — a typical iterative step that keeps the pickup competitive.
