BMW M440i Alternator

The BMW M440i Alternator delivers a continuous supply of electricity that keeps everything running while supporting the sporty character of the coupe. The Alternator guarantees that the lights, sensors, and ignition are activated instantaneously throughout the entire BMW electrical network by producing a reliable current. It does this by converting the crankshaft motion. Within its twin cast aluminum shells resides a finely balanced rotor and stator. This robust construction is the reason BMW owners enjoy a reputation for reliability. Regardless of being outfitted to a rear drive M440i or an xDrive M440i or a future model year update, the same factory tuned Alternator is a factory part and fits as designed. It has the same mounting points and voltage protocols. The smart field current control, under the command of the car's PCM, allows the Alternator to prevent power spikes that can damage the recent infotainment screens that define the M440i cabin. The Alternator increases fuel efficiency by cutting wasteful draw at idle and ramping output when the turbocharged six begins to surge because the BMW engine is never made to work harder than necessary to charge. By maintaining a stable voltage, these features also enable advanced driver assistance functions which contribute to the safety aspect of the BMW performance mission. During cold starts, spirited accelerations, and lengthy journeys at night, drivers feel the benefit of the Alternator which silently does its job with unwavering amperage. The internal cooling fans, high-quality bearings, and tightly toleranced diodes of the unit enable it to resist heat, vibration, and high revs. These qualities match the ambitious duty cycle of every M440i. As the Alternator was developed alongside the core electrical architecture of the BMW platform, it delivers factory grade compatibility, maintaining warranty assurance while giving the M440i that edge in the consistent, hassle-free delivery of power. This is the kind of delivery few rivals offer.
