Pro mod­u­lar; no cons

Wheels (Australia) - - John Carey -

BMW’S cau­tious elec­tri­fi­ca­tion strategy is based around the devel­op­ment of a mod­u­lar com­po­nent set, with bat­tery packs and mo­tor units set to be used in mul­ti­ple ap­pli­ca­tions. Key to it is an im­pres­sively com­pact new ‘Heat’ unit which com­bines an elec­tric mo­tor, con­trol elec­tron­ics and a re­duc­tion gear­box into a sin­gle cas­ing, pro­vid­ing power out­puts from 100kw to more than 300kw. Pure EVS will have one or two of th­ese, while hy­brids will use one to power one axle while a con­ven­tional com­bus­tion en­gine turns the other.
