The new ‘Le Fil Rouge’ concept car embodies Hyundai’s desire to find the perfect harmony between feeling and function. A ‘light architecture’ construction, the car uses golden-ratio proportion to create a forward motion effect, with front and rear pillars and roof treated as a single, sinuous line that runs from front to rear. Le Fil Rouge has a long wheelbase, large wheels and short overhangs, with signature cascading grille incorporating parametric jewel lighting. Elsewhere, the key exterior surfaces are formed of generous curvatures, which seamlessly intersect and embrace the passenger space - a deliberate design strategy known as tube architecture.
