The sporty, flat silhouette provides an impressive body height of just under 1.40 metres. This makes the BMW Gran Coupé Concept 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 forward-tilted shark nose visually extends the bonnet and creates characteristic BMW proportions with its forward-pointing dynamism. 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 Gran Coupé Concept a modern character since the glass surfaces appear to merge seamlessly without being interrupted by columns.
