Each time you brake, kinetic energy is released which, until recently, remained unused. Brake Energy Regeneration exploits this previously untapped potential by taking the energy produced whenever you brake or take your foot off the accelerator and converting it into electricity.
This energy is used to charge the battery. Thanks to this intelligent energy-management system, the alternator does not need to run permanently, which relieves strain on the generator. The result? Lower fuel consumption and higher performance – just as BMW EfficentDynamics intended.
