A product of the controvertial BMW designer chief, Chris
Bangle, the BMW X-Coupe was the first of his 'Flame Surfacing'
concepts.
This design philosophy uses body panels which turn back
on themselves in a series of convex and concave lines.
Flame surfacing can be seen in various degrees on all
current BMW designs.
The BMW
Z4 Coupe is probably the closest production model
to the X-Coupe.
