Sport and Luxury-grade models have been gifted with lightly tweaked front bumper plastics and the rear bumper fascia has been recontoured to match, but sheetmetal is unchanged for the 2017 model year. You can, however, now opt for one of two fresh paint hues: Sunset Orange or Snapper Rocks Blue.
Greater changes are afoot inside the updated 4 Series range. BMW’s latest generation of its high-end Navigation System Professional has been fitted, with new tile-style graphics and a sleeker interface that brings the 4 Series’ infotainment system into line with that of the new 5 Series and BMW 7 Series.
A reconfigurable all-electronic ‘Multifunctional Instrument Display’ is also available.
The cabin is also jazzed up with a double-stitched dash top, more premium-looking electroplated switchgear feel and the restrained application of chrome and piano black highlights. The basic design and layout, however, carries over with no changes.
More meaningful mechanical updates have been carried out beneath the skin. A revised suspension tune brings firmer springs and dampers for not only the standard fixed-rate suspension, but also for the optional M Sport and electronically-adjustable Adaptive suspension. BMW says the firmer undercarriage results in greater stability and more communicative steering without compromising ride comfort.
It’s a modest update for the 4 Series range, which sees no changes applied to powertrains or transmissions. Power outputs and fuel economy are identical for the full range of petrol and diesel engines – which encompass a 135kW turbo petrol four-cylinder in the entry-level 420i to the flagship M4’s potent 317kW turbo petrol inline six.
Due to roll out in Europe towards the end of March, expect the updated 4 Series to arrive locally sometime in the second half of the year.
