stunning little Z4 roadster replaced the much softer BMW Z3 roadster. The BMW Z4 is one of the most
successful of Chris Bangle's controversial 'flame surfacing'
designs. Flame surfacing is the name which has been given to
his style of colliding lines intersecting each other at seemingly
random points, causing a wide variety of unusual shadows and
highlights to show up all over the cars body.
In 2006 a coupe version of the Z4 roadster was revealed which
is intended to compete with the Porsche Cayman S for sales.
