Update: August 9, 2017
The G20 3 Series has finally revealed some production parts as we now get our first look at the production LED headlights and tail lights. These headlights feature a closed loop design. It remains to be seen whether these are intended for the base model, with higher end models featuring the current open L-shaped styling.
And while we now see the lighting elements of the production tail lights, their overall shape is still obscured by the camouflage.
