Piston assembly minimum mass

In Simple Terms

F1 engines must use pistons that weigh at least 350 grams, including the piston pin, retainers, and rings. This minimum weight requirement ensures all teams use similarly robust engine components and prevents unfair advantages from using overly lightweight parts.

• Minimum piston assembly weight is 350 grams
• Includes the piston, piston-pin, piston-pin retainers, and piston rings in the total weight
• Prevents teams from gaining unfair advantages through extreme weight reduction
• Ensures component durability and reliability across all F1 engines
