Yes, this is the 1992 Chevrolet Lumina Sizigi. The design has some interesting factors, though. The intent was to show the revised short nose of the 1994 Lumina Dustbuster minivan. Still, when you compare them, there are some pretty significant differences between this and the actual production model. The name, Sizigi, is derived from the philosophical term 'syzygy' proposed by Russian philosopher Vladimir Solovyov in the late-19th century.
