What is the displacement of F1 racing cars?

F1 racing cars typically have a displacement of 1.6 liters. Here is detailed information about F1 racing cars: Engine specifications: An F1 racing car engine consists of approximately 900 moving parts, with a maximum RPM exceeding 19,000 revolutions per minute, far surpassing that of ordinary cars. When an F1 engine operates at peak speed, the spark plugs ignite 150 times per second, pistons complete 300 reciprocating cycles, and the acceleration reaches up to 8500G. Additionally, the weight of an F1 racing engine does not exceed 100kg. Reasons for powerful performance: The use of turbocharging significantly enhances the power of F1 racing cars, representing the most direct method to boost performance without increasing displacement. Another factor contributing to their powerful performance lies in RPM tuning - idle speed reaches about 5,000 RPM while maximum RPM can achieve 15,000 RPM. High RPM ensures power output and facilitates turbocharger performance, enabling F1 racing cars to deliver formidable power output.
