Brake Energy Regeneration.
Every time you brake, kinetic energy is generated, and until recently, this energy has gone unused.
Brake Energy Regeneration takes advantage of this long-overlooked potential. It harnesses the coasting energy that is generated whenever the driver brakes or takes their foot off the accelerator and turns it into electricity. This electricity is then used to charge the car battery. The intelligent energy management system means that the alternator no longer needs to run permanently, which reduces the strain on the generator. The result is reduced fuel consumption and increased performance – classic BMW EfficientDynamics.
