BMW Z4 CONCEPT

The BMW Group has used the 2017 Concours d'Elegance at Pebble Beach to present its exciting new take on a BMW roadster. Dynamic, progressive and an irresistible purveyor of thrills, the BMW Concept Z4 boasts lithe and compact proportions, a dynamic silhouette and an emotionally appealing use of forms. The attention-grabbing design study offers a look ahead to the series-production version of the car set to be unveiled over the course of next year.

"The BMW Concept Z4 in an all-out driving machine," said Adrian van Hooydonk, Senior Vice President BMW Group Design. "Stripping the car back to the bare essentials allows the driver to experience all the ingredients of motoring pleasure with supreme directness. This is total freedom on four wheels."

A statement of unbridled driving pleasure

The sporty and progressive BMW Concept Z4 encapsulates the BMW Group's vision of a modern roadster. "The BMW Concept Z4 expresses the new BMW design language from all perspectives and in all details. From the dynamic-looking front to the striking flanks to the clean-cut tail end: a few lines and the subtle interplay between surfaces are enough to generate a sense of power and emotion," adds van Hooydonk.

BMW's roadster tradition, reloaded

The BMW Concept Z4 adopts classical roadster design cues, such as a long wheelbase, a low-slung, stretched silhouette and a compact rear end, wraps them in a fresh, confident package and enriches them with the contemporary BMW design language. A shorter bonnet and crisp overhangs ensure the driver sits closer to the centre of the car than in previous BMW roadsters. This gives the new proportions a focused, sporty and agile feel. The outline of the car follows a distinct wedge shape, which fills the BMW Concept Z4 with dynamism before it even pulls away. The large domes stretching out rearwards from the cabin elegantly integrate the function of rollover bars and provide a sporting conclusion to the low-to-the-road silhouette at the rear.

Reimagining the design language and surfaces

The clearly sculpted shark nose at the front end spawns dramatic surface contouring that extends the full length of the flanks. The new direction taken by BMW's design language can be seen here in just a few precise lines that form clear surfaces, while the body's volumes are powerfully sculpted. The surfaces and forms therefore create an extremely modern and emotionally engaging impression. The large Air Breathers rearwards of the front wheels act as the source of the flanks' elaborately modelled surfaces (they appear to be shaped by the flow of air as it exits the Air Breathers). Light and shaded surfaces develop in a rising movement towards the rear, then twist to form muscular wheel arches and athletic volumes. All of which shines a bright stylistic spotlight on the car's rear-wheel drive. The dramatic interplay of lines and surfaces underscores the wedge shape of the flanks and infuses them with even greater dynamism. And the low door sills, with their distinctive crease, makes the body appear closer to the road, emphasising the low-slung sensation when viewing the car from the side.

The expressive Energetic Orange frozen exterior paint finish showcases the contrasts of light and shade in the surfacing, accentuating the three-dimensionality of the exterior. And the 20-inch light-alloy wheels in a sporty bi-colour double-spoke design provide harmonious finishing touches to the styling of the flanks.

Low and progressive - the front end

The design of the BMW Concept Z4's front end is undeniably sporty in nature. The relationship between the low-set, broad kidney grille and the positioning of the headlights higher up sparks deliberate associations with the BMW Z8 and lends the BMW Concept Z4 a certain flamboyance. In place of the customary bars, the inside of the kidney grille features elaborately designed mesh, whose vertical orientation recalls the sporty, functional kidney design of early BMW roadsters such as the BMW 328 Mille Miglia. In a departure from the BMW norm, the Concept Z4 provides a vertical interpretation of the classical four-eyed headlight look, with two overlapping tubes on each side. The turn signal indicators point diagonally towards the kidneys from above and underline the dynamic flair of the front end. And the clamshell bonnet with stylised gill vents curves over the wheels, creating an intriguing and virtually seamless sweep over the front end as a whole.
