Connecting rod minimum mass

In Simple Terms

F1 engines must use connecting rods (the parts that connect pistons to the crankshaft) that weigh at least 320 grams when fully assembled. This minimum weight requirement ensures structural integrity and prevents teams from making rods too light, which could cause engine failure during the extreme forces of racing.

• Connecting rods must weigh a minimum of 320 grams including all fasteners and bearings
• This rule applies to the complete assembly of both the small end (piston side) and big end (crankshaft side) with their bearings
• The weight requirement ensures engine durability and prevents catastrophic mechanical failures
• Teams cannot attempt to reduce engine weight by using dangerously thin connecting rods
