The 2019 IAA Cars show in Frankfurt was the venue for the unveiling of the BMW Concept 4 – a future-focused interpretation of the BMW Group’s enduring DNA that represents the magic of coupe driving at its most exciting.
The slim and focused twin headlights are slightly angled and team up with the kidney grille to lend the front end a modern look with a strong identity. The striking LED light elements have no glass cover; instead they are worked into the body like three-dimensional sculptures. This allows them to bring an even greater sense of modernity and technical sophistication to the front end. The sharply contoured bonnet extends the lines of the front end through powerful volumes and edging of precision. The bold surfacing frames the kidney grille like a gemstone.
The side – the aesthetic essence of a modern BMW coupe
The BMW Concept 4 displays BMW’s signature proportions at their most modern form yet. The stretched bonnet, long wheelbase, flowing roofline and short overhangs create a modern, elegant and dynamic coupe outline and send energy coursing through the low-slung body even while it’s standing still. Within the silhouette, the ultra-pure surfaces of the new BMW Concept 4 form a powerful main body. The interplay of tautly chiselled volumes and a small number of extremely precise contours create a rare sense of emotion and dynamism. The expressive exterior paint tone Forbidden Red accentuates the car’s surfaces particularly vividly; those in the light at any one time project a rich, glossy red, while shade creates an almost black effect and a striking contrast. The interaction of contours and volumes therefore exude a dramatic sense of radiance and depth.
The athletic body incorporates a slender glasshouse with a narrow window aperture, which further emphasises the dynamism of the side. The long, sweeping roofline flows smoothly into the boot lid, giving the rear end a high-class and sporty aesthetic. The bulging rear wheel arches lend visual expression to the power coursing through the rear wheels and accentuate the muscular shoulders higher up. The slender area above the front wheels, meanwhile, strikes a neat dynamic balance. Its tempered volumes enhance visual agility and lightness. Together, the two sets of wheel arches give the new BMW Concept 4 a powerful and confident stance.
A horizontal main line between the wheel arches takes the place of a classical contour line in shaping the character of the flanks. It runs relative low down along the side of the car, creating a low visual centre of gravity. Further down, another character line rises dynamically from the rear of the front wheels towards the boot lid, bringing extra agility into the mix.
Sophisticated details at second glance
Look at the BMW Concept 4 more closely and further classy details are revealed. The minimalist, two-section exterior mirrors emerge harmoniously out of the weather strips. The lower section in polished aluminium extends the weather strip in a flowing movement and becomes a mirror surface, while the aerodynamically optimised rear section is in body colour and rounds off the design of the mirrors in dynamic fashion. On the inside of the mirrors is an apparently floating BMW logo, which only comes to light on more detailed inspection.
The light-alloy wheels of the BMW Concept 4 are equally rich in detail. The 21-inch items represent a heavily « dished » take on the sporty five-spoke design, drawing the eye into their centre-points. The fronts of the intricate spokes have a high-polished finish, while the set-back surfaces are finely ground to create a slightly darker effect and give the rim design a sophisticated contrast.
The rear end – clear, eye-catching, dynamic
The rear of the BMW Concept 4 sits low over the road, as befits a sporty car. The character line transitions from the flanks into the rear end in a broad, horizontal sweep and visually reduces the coupe’s height off the ground even further. Picking up where the front end left off, generously sized and clear surfaces with only a small number of lines are the dominant theme. Purism runs through every element of the rear end and creates a prominent tail graphic. The sporty glasshouse is indented into the powerful body, allowing it to chisel broad and athletic shoulders into the BMW Concept 4’s design. The vertical air outlets frame the lower section of the rear and emphasise the car’s broad stance. The LED rear lights consist of a single fibre-optic element, which lends the familiar BMW L shape a cutting-edge « heartbeat » graphic and dispenses with a glass cover. Their contours underscore the sportingly horizontal focus of the rear end and accentuate its brawny stance on the road. The striking diffuser integrated into the muscular rear apron sets the seal on the car’s rear-end design. Its vertical fins break up the clean surfaces of the car’s tail to send a statement of fine sporting pedigree, while the High-gloss Black paint finish with metallic particles lend it additional visual impact. The pair of exhaust tailpipes highlight a new and dynamic free-form, a detail of the BMW Concept 4’s design that expresses what this car is all about: the modern essence of a coupe oozing aesthetic appeal from every pore.
