Here you will find monthly and yearly U.S. sales figures for the BMW i-Series. We all know electric vehicles are the future and BMW is going all out to be at the forefront of this monumental market shift. The BMW Group offers a total of seven electrified vehicles, the broadest range of any manufacturer, selling across the BMW brand as well as Mini too. BMW has a sub brand that it calls the “i-series” for vehicles that stand on their own (vs being part of the traditional 3, 5, 7 series model ranges). In BMWs case today that is two models, the BMW i3 and the BMW i8.
