The modern Formula One power unit (PU) is a tightly integrated thermodynamic system consisting of a high-efficiency internal combustion engine (ICE) coupled with dual electric motor-generators and sophisticated control electronics. Since 2014, technical directives have enforced the hybridisation of propulsion systems, culminating in highly constrained yet optimised energy flow architectures. | The modern Formula One power unit (PU) is a tightly integrated thermodynamic system consisting of a high-efficiency internal combustion engine (ICE) coupled with dual electric motor-generators and sophisticated control electronics.
