BMW’s next-generation Neue Klasse electric vehicles are set to use Samsung SDI 46-series cylindrical battery cells, a shift that could raise driving range by up to 30% and improve charging speed by about 30% compared with the prismatic cells used today.
The agreement extends a 17-year relationship between BMW and Samsung SDI. Samsung SDI will supply two 46 mm-diameter cell formats for BMW’s sixth-generation, or Gen6, battery system: the 4695 cell, which is 95 mm tall, and the 46120 cell, which measures 120 mm in height.
BMW is also working with LG Energy Solution, CATL and EVE Energy on Gen6 battery-cell supply. The broader supplier roster is intended to support production across BMW’s regional manufacturing footprint while limiting transport distances between battery plants and vehicle factories in Europe, Asia and North America.
Samsung SDI is preparing a new production line at its Göd plant in Hungary for the 46-series cylindrical cells. Mass production is scheduled to begin in 2028, making that timetable the key milestone for BMW’s expanded Samsung SDI battery program.
