The curved front section with wide wind intake vents and the elegant shape of the headlights deflects wind in all directions as it passes the flexed arch of the bonnet with its poignant character lines that taper towards the emblem. Accelerating as it moves over the long curving lines of its gently sloping rear with BMW-familiar L-shape taillights, it then disappears as quickly as it arrived - the BMW 3 Series Touring continues on unperturbed leaving wind resistance far behind.
