The BMW Concept X4

05 Apr, 2013

Every new BMW X model is a trailblazer.  Indeed, the world premiere of the first BMW X model (the BMW X5) in  1999 saw the BMW Group call into being the Sports Activity Vehicle  (SAV) segment – one in which BMW X models remain the market leaders.  The BMW X3 and BMW X1 were likewise the first SAVs in their class and  continue to set the pace among their rivals today. This development  took on a new dimension in May 2008 with the introduction of the BMW  X6 – the first Sports Activity Coupe (SAC). This still unique concept  brought together the rugged looks of a BMW X model with the emotional  aura and sporting character of a BMW Coupe for the first time. The  enduring popularity of BMW’s first SAC is borne out by its  consistently high sales figures. The short history of the BMW X range  is already a successful one. Since the first BMW X model took to the  stage, average sales across the BMW X line-up have progressed on a  constant upward curve: one in four new BMW cars is now a BMW X model.

With the BMW Concept X4, the BMW Group offers a preview of the future  of the BMW X family. It takes no more than a first glance to see how  smoothly the qualities of a BMW X model can blend with the genes of a  BMW Coupe. The new Sports Activity Coupe concept from BMW is poised to  continue the success story of the BMW X6 in a new vehicle class.  Eye-catching proportions, tight contours and numerous high-quality  details produce an unrivalled product character brimming with  emotional appeal, dynamism and the sturdiness you would expect from a  BMW X model, while at the same time holding out the promise of  outstanding performance and driving dynamics. All of this can be  experienced when the BMW X4 production model rolls out of the factory  for its market launch, scheduled for as early as 2014. The second  Sporty Activity Coupe in the brand´s model range will be built at BMW  Plant Spartanburg in the USA, the competence centre for BMW X models  which also produces the BMW X5, BMW X6 and BMW X3.

The sporting character of the BMW Concept X4 is articulated by its  dynamic linework as well as its proportions. With a body length of  4,648 mm, a wifth of 1,915 mm and a height of 1,622 mm, its exterior  dimensions signal sporting elegance and powerful robustness. In  addition t a long bonnet, short overhangs and set back passenger cell,  its signature BMW features include a long wheelbase measuring 2,810  mm, while 21 inch light alloy wheels lend an added flourish to the  athletic bearing of this Sports Activity Coupe.


A front end with an urban sporting presence.

The front-end styling of the BMW Concept X4 exudes hallmark BMW dynamics and the rugged purpose and presence of a BMW X model in equal measure. Classical BMW features such as the kidney grille and stylised twin circular headlights give the front end a clear identity and ensure it shines out as a BMW the first time you set eyes on it. The BMW Concept X4 lavishes both these front-end design icons with meticulous detail and three-dimensional depth. The large kidney grille stretches out within a solid-looking surround. The high-gloss frame is open to the sides and at its lower extreme, lending it an almost “floating” appearance in the centre of the front end. The grille features prominently sculptured bars with ultra-stylish detailing. The hollowed out, high-gloss black bars have a milled lower third with a matt finishing, which lends the kidney structure extra visual depth. And the grille also comprises additional air apertures to ensure an increased supply of cooling air to the engine.

The kidney grille is flanked by dynamically contoured full-LED  headlights. Inside the light units, a flowing, hexagonal  interpretation of the familiar BMW twin circular appearance points to  an unwavering focus on the road ahead. The horizontal continuation of  the inner light elements creates a visual connection with the grille,  accentuating once again the width of the front end.

This dynamic impression extends to the front apron. In keeping  with BMW Coupe tradition, the side air intakes are larger than  the inner units and make a visual feature of the increased cooling air  requirement – while satisfying that need. Together with the car’s wide  track and low centre of gravity, the intakes represent a promise of  exceptional performance capability. The side air intakes pick up on a  stylistic theme from the kidney grille; their black horizontal bars  are, like the grille’s, partly milled out but boast gleaming chrome  edges. It all makes for an enticing contrast of materials, a fusion of  high-end quality with the characteristic robustness of BMW X  vehicles. This design theme concludes in the underride protection  element, where three milled out, gleaming chrome elements present a  high-quality take on the modern preference for minimalist solidity.


Side view with an extrovert edge.

The qualities of a BMW X model merge with the values of a BMW Coupe  in the muscular silhouette of the BMW Concept X4. Its proportions  present a persuasive case for the BMW Concept X4 as the most dynamic  vehicle in its segment. In hallmark BMW style, a longer wheelbase,  relatively long bonnet, short overhangs and a set-back greenhouse lend  the car an undeniable dynamism even when standing still. The striking  interplay of surfaces creates a vibrant contrast of light and shadow  that exudes a feeling of agility and power. Prominently rising lines  mould the flanks into a wedge shape and give the car as a whole a  forward-surging momentum.

The coupe-style roofline sweeps elegantly downwards and makes the car  appear longer. Below, the windows extend well to the rear, where they  are bordered by a dynamic interpretation of BMW’s signature Hofmeister  kink. The stretched and shallow band of glass creates a persuasively  dynamic link between the greenhouse and vehicle body, the slim glass  surface giving the body an impressively powerful appearance. At the  same time the visual centre of gravity is lowered, underlining the  sporting mission statement summed up by the car’s flanks.

The BMW Concept X4’s contours include a new interpretation of the  familiar BMW swage line, a pair of dynamic lines defining the  eye-catching impact of the side view. A concave area under each swage  line lends the flanks an almost sculptural expression – at once robust  and dynamic. The surface volumes and definition of the contours deepen  as they extend towards the tail and imbue the rear end with added  stature. Here, the powerfully flared wheel arches team up with the  concave surface below the rear swage line to visualise the power  rippling through the rear wheels. The radiant exterior paint shade  Long Beach Blue is a perfect match for the elaborately structured  volumes and contours, and brings particular depth to the expressive  design language.

Fitting the BMW X template, the wheel arches of the BMW Concept X4  are large and almost square in design. This prominent emphasis on the  wheels draws further attention to the car’s planted stance and long  wheelbase, while at the same time providing a visual showcase for the  xDrive intelligent all-wheel-drive system. The pared-back, matt black  protective cladding provides the final element of bodywork before the  BMW Concept X4 meets the road.

Expressive 21-inch bi-colour light-alloy wheels round off the car’s  appearance when viewed from the side. Intricate, high-gloss polished  spokes provide visual allure, while behind them dark-coloured flame  surfaces contribute an impressive feeling of depth.


Cutting-edge presence for the rear.

The rear of the BMW Concept X4 takes the sporting, width-accentuating  elements of the front-end design and reproduces them with an  emphatically horizontal flavour. The body’s lines and the slim LED  tail lights positioned at the outer edges of the rear emphasise the  muscular wheel arches and wide track. Below, horizontal lines split  the rear visually into sections, while light surfaces reduce the car’s  visual height and underline its width.

The shallow rear window gives the vehicle body an even more powerful  impression and its broad shoulders a show-stealing presence. Looking  further down, the L-shaped rear lights of the BMW Concept X4  underscore its consummate stance on the road. A full-sized inner  element in the tail lights, meanwhile, replicates the signature BMW  “L” shape in three-dimensional form and with impressive depth.

The most striking element at the back of the car is the rear apron,  which provides a wide, full-length interpretation of the front apron’s  large outer air intakes. The apron’s cut-out picks up the two exhaust  tailpipes in a dynamic sweep before diverting the gaze to the wheels.  Body-colour elements reaching well down towards the road surface  provide a high-quality border for the rear end and re-emphasize the  road-focused proposition of the BMW Concept X4.

The underride protection acts as the body’s lowest edge. Matt black  surfaces lower the car’s perceived height and accentuate the robust  BMW X character of the rear. As at the front of the car, three milled  elements in gleaming chrome add a sophisticated touch to the underride protection.
