Blending this striking visual element with functional performance benefits lends legitimacy to the design. Side sculpting shows that GM still knows how to sculpt surfaces for a dramatic interplay with natural lighting along the shoulder line of a vehicle, which is a type of visual functionality.
On the opposite end of the spectrum, the highly controversial front grill of the BMW iX shows no evidence of function and appears entirely ornamental, serving brand purposes alone. Perhaps this lack of a tie to functionality makes this design feature subject to opinions. Both are bold, but the LZ-1 design benefits from being grounded in function, lending credibility to the design.
