The BMW Concept Z4 adopts classic 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 center 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.
