The E63 BMW 6 Series (2003–2010) was designed by Adrian van Hooydonk under the direction of BMW Design Chief Chris Bangle, with inspiration heavily drawn from the 1999 BMW Z9 concept car. The design featured "flame surfacing"—concave and convex shapes—and was intended to modernize the grand tourer, with Bangle driving the bold, often controversial aesthetic. Lead Designer (Exterior): Adrian van Hooydonk. Design Director: Chris Bangle. Inspiration: The 1999 Z9 concept, designed to bring "flame surfacing" (where concave and convex shapes meet) to production. Key Design Elements: Often criticized but iconic "Bangle Butt" rear styling, long hood, and a "shark nose" tribute to the original E24 6 Series. Production Context: The car was developed with lightweight materials, including aluminum doors/bonnet and carbon-reinforced plastic wings and boot. The E63 6 Series served as a modern return to the 8 Series/6 Series GT segment, with its design philosophy aimed at challenging traditional, evolutionary styling. Key Aerodynamic Differences: Convex Surfaces: Promotes flow acceleration and pressure reduction (low pressure), crucial for lift generation on top of airfoils, according to NASA Technical Reports Server and Aviation Stack Exchange. They generally offer better lift-to-drag ratios for cruising. Concave Surfaces: Often used to increase camber and lift, but frequently increase drag. They are effective when used as the pressure side (bottom) of a wing at high angles of attack or in, for example, high-lift devices, notes The College of Wooster and Aviation Stack Exchange.
