This is a car that is still intensively disguised in pre-production form.
This is the first prototypes off the production line and begin a new phase of development to make sure everything is reliable and performs well so the car can be signed off for series production.
The concept as I have mentioned previously regarding BMW "Preview" concepts is 90% the final car , Here you do not see the full picture , cosmetics are not compulsory at this stage some cars have them and some cars do not. It all depends how good the photographers are.
Just be patient.
