The energy recovery system is a complex hybrid powertrain component, most notably used in Formula One, that scavenges otherwise wasted energy from the brakes and exhaust. It stores this energy in a battery pack and deploys it through electric motors connected to the drivetrain and turbocharger, providing a massive temporary horsepower boost.
