After the 3 Series sedan and wagon received updates last year, it's now the 4 Series' turn to get a host of changes. BMW will be giving the 4 Series line the LCI or Life Cycle Impulse treatment, the automaker's term for minor model change.
BMW LCI models get subtle exterior tweaks and the 4 Series will be no exception. Underneath the disguise is a new shape front bumper, as well as slightly reworked headlights. Seen on this test car are a set of LED headlights, also an upgrade from last year's 3 Series LCI. The heavily camouflaged rear end also hints at reshaped bumpers and redesigned tail light clusters.
Inside, expect minor tweaks and perhaps new software for BMW's iDrive system. Being based on the 3 Series, WLAN hotspot and LTE connectivity will also be available for the 4-Series. These changes will be applied to the rest of the 4 Series line which also includes the Cabrio and Gran Coupe. Same applies for the exterior changes.
For its engines, the 4 Series will be powered by BMW's new four and six cylinder turbocharged gas engines, as well as a new six cylinder turbodiesel. The four-cylinder turbodiesel gets mild tweaks, just like the 3 Series. The nomenclature will likely be changed with the 428i becoming the 430i and the 435i becoming the 440i. It is yet unknown if the 4 Series will be getting a plug-in hybrid variant. The 4 Series LCI is expected to break cover by late 2016.
