The floating roof mentioned in the iX and i3 is present in half of Chinese models, the shapes that give personality to the bodywork, the small details on the bumpers, the body creases, the shapes of the front and hood in relation to the windshield giving the design a strong presence—if you investigate, you'll find that the brand's developments over the years have influenced many models of other brands. For example, flame surfacing has evolved in one way or another to become the standard for lots of brands today, and BMW isn't the only one. Mercedes and Audi (among others) have also set the standard in many aspects for the rest of the industry.
Land Rover has had the floating roof for a lot longer than BMW has used it, so were BMW copying them?
