Presented at the 2010 Beijing Auto Show, the BMW Concept Gran Coupé is a four-door coupé that incorporates the classic design features of all BMW coupes: the long wheelbase, the vaulted hood with forward-pointing lines, the set-back greenhouse, the flat silhouette, the coupe-style roof line and the short front overhang reflect the dynamic potential of the vehicle.
The proportions are characterized by a length of almost 5 metres, a height of just under 1.40 metres and a low centre of gravity which reflects the body’s aerodynamic efficiency.
The BMW Concept Gran Coupé up to 100 millimetres flatter than the BMW 5 Series or the BMW 7 Series Sedan. The roof line tapers off gently into the rear, thereby elongating the vehicle’s proportions.
The kidney grille of the BMW Concept Gran Coupé has a flat appearance, with an asymmetrical side view which emphasises the close attention to detail.
The central section with the kidney grille is formally separated from other BMW icons such as the headlights and air inlets. The clarity of the LED front lights highlights the vehicle’s precision and premium aspirations.
The air inlet runs back an extremely long way into the side section, making the front section appear particularly wide. All elements of the front section appear to merge to form a single, elegantly curved movement.
This stretched character is also highlighted by the side lines, where there is a deliberate avoidance of the typical sill line. The flat proportions make the window graphics appear extremely narrow and dynamic at the same time.
Another BMW design icon, the Hofmeister kink, is especially strikingly formed – additionally emphasising the exclusive character of the vehicle. The frameless doors give the BMW Concept Gran Coupé a modern character since the glass surfaces appear to merge seamlessly without being interrupted by columns.
At the rear, only design elements such as the lights and tailpipe trim appear to be visible at first sight. The entire rear section appears slimmer and lighter at the centre, though still exuding power and dynamic performance since the volume is reinforced towards the sides.
The L-shaped light banks feature a slight, almost subtle curve and the entire design of the lines and surfaces highlights the vehicle’s elegant overall appearance.
The third brake light, positioned in the rear window, is also fitted with LED technology. It takes up the kink in the roof and illuminates the entire width of the rear window. The powerfully flared wheel arches above the rear axle highlight the particularly sporty character of the BMW Concept Gran Coupé.
Another highly sporty and also elegant feature is the rim concept in which the individual spokes extend deep into the centre of the rim towards the hub, giving the rim a striking three-dimensional quality. The spokes themselves are not solid but relief-milled, giving them a visual lightness.
The sculptural shaping style characteristic of the entire body design of the BMW Concept Gran Coupé permits a unique interaction between concave and convex surfaces. It also enables the light to be selectively reflected and channelled.
Thus the exterior mirrors integrated in the window shaft appear very light, blending harmoniously into the side view since their shape assimilates the entire line styling.
