Energy Recovery Systems, or ERS for short, consist of Motor Generator Units that harness waste heat energy (from the turbocharger) and waste kinetic energy (from the braking system). This energy is then stored and subsequently used to propel the car. An F1 car has two ERS: MGU-K (which stands for Motor Generator Unit – Kinetic) and MGU-H (which stands for Motor Generator Unit – Heat). These systems are complemented by an Energy Store (ES) and control electronics. ERS is capable of providing 120kw of power (approximately 160bhp) for approximately 33 seconds per lap
