Updated in 2021, the facelifted BMW X4 G02 LCI brought sharper exterior styling, redesigned mesh kidney grilles, slimmer adaptive LED headlights and an upgraded centre console featuring a 12.3-inch infotainment display. Crucially, almost all four- and six-cylinder combustion engines adopted 48V mild-hybrid electrification for smoother stop-start response and lower emissions. Maintaining this refined sports coupé calls for structured BMW X4 maintenance, where electrical and software health are paramount alongside mechanical care.
The powertrain family comprises the 48V mild hybrid B47 diesels (20d), the B57 straight-six diesels (30d, M40d), the B48 petrol (20i) and the sensational B58 petrol (M40i). All variants route power through the quick-shifting ZF 8-speed automatic gearbox and rear-biased xDrive. The electrical architecture features an integrated starter-generator and dedicated 48V lithium-ion battery that assists acceleration and recuperates braking energy.
