Last week we published spy photos of the next-generation 1 Series hatch, which will likely be revealed towards the end of next year or the beginning of 2019.
The second update for the current 1 Series isn't anywhere near as dramatic as the 2015 facelift, which included restyled bumpers, lights and tailgate.
As the prototype has just a little bit of disguise tape around the head- and tail-lights, and grille, visible changes may be limited to new headlamp internals, lighting graphics and grille inserts.
BMW may take this opportunity to update the 1 Series' engines, as well as its suite of technology and safety features. Expect tweaks to the car's pricing and specifications to keep the 1 Series competitive until the new third-generation model is released.
With so little disguise on the car, it's likely the updated 1 Series will appear in the not-too-distant future, certainly before or at the Frankfurt motor show in September.
