ERS

ERS (Energy Recovery System) is a hybrid technology in motorsport that captures and reuses energy that would otherwise be wasted during driving, providing additional power to the car.

The system works by recovering energy in two main ways: through braking (using the MGU-K component) and from heat in the exhaust gases (using the MGU-H component). This recovered energy is stored in a battery and can be deployed by drivers to provide a power boost of approximately 160 horsepower when needed for overtaking or improving lap times.

Introduced in Formula 1 in 2014 as an evolution of the earlier KERS system, ERS has become a critical part of modern racing strategy. Drivers must carefully manage their energy deployment throughout a race, adding another layer of skill and tactical thinking to the sport.
