The media preview days of the 2019 Frankfurt IAA brought a few surprises. Volkswagen (a camouflaged and altered I.D. Crozz which will be called ID.4), Hyundai (i30 N Project C), FAW (Hongqi S9 & E115 prototypes) and BMW (i Hydrogen Next, and the Concept 4: yes, the one with THAT grille) were among the OEMs showing unheralded vehicles.
