Prominent examples of this are the large air intakes, which allow for the engine’s higher cooling requirements, as well as optimised aerodynamics thanks to a discreet spoiler located on the boot lid and a diffuser integrate into the rear apron.
The BMW Concept M5 owes its intense emotional impact to the direct relation of each detail with the technical requirements. At the same time, the concise styling of the high-performance car’s specific features creates the character of understatement that is typical of a BMW M automobile. The car’s superior appearance is underlined by the body colour Chrome Shadow. The discreet appearance of this body colour distinctively enhances the surface contours of the vehicle’s three-dimensionally modelled bodywork.
Front apron: precise airflow optimises cooling and aerodynamics.
Dynamic lines and large air intakes on the front end of the BMW Concept M5 are a clear implication of the vehicle’s exceptionally sport-oriented characteristics and its engine’s outstanding power. Like on the BMW 5 Series Sedan, the contour lines on the bonnet of the BMW Concept M5 flow towards the BMW kidney grille. The upright position of the widely stretched kidney grille also signalises dynamic forward movement. The dual round bi-xenon headlights, which are complemented at the top by an accentuating light, create the road-focused look that is also characteristic of BMW M automobiles.
The front apron, which was designed exclusively for the BMW Concept M5, contributes significantly towards both the car’s athletic appearance as well as its dynamic potential. It features three large air intakes, the dimensions of which are precisely oriented towards the high cooling requirement of the engine and its ancillary components. The centre opening corresponds to the width of the BMW kidney grille, the side contour lines move away from each other as they continue downwards. This echoes the V shape between the grille and the headlights, thus emphasising the width of the air intake.
The centre air intake protrudes further out than the two outer intakes and its contours are slightly curved. This three-dimensional design and the deeply embedded, black grille sporting a honeycomb design additionally underscore
the vehicle’s powerful character. With concisely designed so-called flaps on the lower edges of the outer air intakes, the BMW Concept M5 boasts a racing-inspired feature for optimising airflow. These also emphasise a front apron design that is oriented towards the technical demands.
Side view: dynamically flowing lines, large M light alloy wheels.
With powerfully modelled wheel arches and dynamically flowing lines, the BMW Concept M5 also signalises uncompromising sportiness when viewed from the side. The long wheelbase, the set back passenger cabin and the black side window surrounds distinctively underscore the sedan’s stretched silhouette. This appearance is even more strongly emphasised through M-specific lowering of the vehicle.
The athletically flared wheel arches are complemented by M-specific light alloy wheels sporting a double-spoke design. Due to the vehicle’s wide track, they are flush with the car body. The 20-inch forged rims are fitted with tyre size 265/35 ZR20 at the front and 265/35 ZR20 at the back.
The M-typical gill element on the front side panel has been reinterpreted on the BMW Concept M5. The gill features a high-quality chrome surround and is horizontally divided by a chrome bar, which in addition to the side indicator also
bears the M logo. The gill element is the starting point of the swage line, which during its further course across the door handles stretches back as far as the taillights.
The rear end: athletic styling, targeted airflow.
Superior sportiness and supreme road holding are effectively symbolised by the BMW Concept M5’s rear end design. The emphasis on vehicle width through dominating horizontal lines also featured on the BMW 5 Series Sedan is combined with an athletically shaped rear apron. The vehicle-specific rear apron, which forms a smooth transition to the wide wheel arches, ensures a particularly intensive accentuation of the motive force that is transferred to the rear wheels.
An integrated diffuser at the lower edge of the rear apron effectuates targeted airflow at the end of the undercarriage. As a typical M identifying feature, the BMW Concept M5 is fitted with a double-flow exhaust system, the double tailpipes of which are located far apart at each side of the diffuser and surrounded by aerodynamically shaped trims.
Likewise, the discreet rear spoiler located on the boot lid serves to optimise the car’s aerodynamic characteristics. It ensures additional downforce above all at high speeds, thus contributing towards supreme handling at all times.
Awe-inspiring power, impressive efficiency: V8 engine with M TwinPower Turbo.
The BMW Concept M5 gives a starting signal for the venture into a new dimension of motor racing-oriented driving dynamics.
