Brake Energy Regeneration in the BMW X1.

Our Brake Energy Regeneration technology uses an intelligent energy management system that actually allows fewer components to draw power from the drive train as you brake and accelerate.
For example, imagine you’re heading into a tight curve. When you brake, the kinetic energy is captured and fed to the battery. This reduces the amount of power the battery takes from the engine, which lowers fuel consumption. And when you hit the accelerator coming out of that curve, the alternator is decoupled from the drive train so that more of the engine’s output can go into accelerating the car. The result is a noticeable reduction in fuel consumption and an exhilarating boost in performance. For you it’s a win-win situation.
