The BMW 3 E90 is reduced by almost 3 per cent thanks to this technology, as well as to the movement on inertia and a deceleration of the fuel flow. If a Brake Energy Regeneration system is present in the vehicle, the generator becomes active as soon as the driver takes the foot off the gas and moves it to the brake pedal. Thus, kinetic energy, which has previously been wasted, is now beginning to be converted into electricity by the generator-that is, to be used for good. It is also worth noting that, in addition to a slight reduction in fuel consumption, the regeneration of energy during braking increases the dynamics of the car.
