General Principles - Permitted Materials

In Simple Terms

F1 teams can only use specific materials approved by the regulations when building their cars (excluding the engine). These materials must be ones that you can actually buy commercially - teams can't use secret or custom-made materials that no one else can get.

• Only materials listed in C15.2 are permitted for car construction
• Specific exceptions are allowed as defined in C15.4
• All permitted materials must be commercially available to the public
• Power Unit components have separate material regulations
