A bit of research indicates that the above drawing is not of the UF torana.
It's actually a design by Phil Zmood for what became known as the Green Lizard (aka the Torana Rotary). I have a photograph of the full scale mock-up which I'll post as soon as I've scanned it. The end result was a recognizable Torana hatchback with a Monza nose, extended tail, and slightly flared guards. It was designed to be a rolling test bed vehicle for one of the early hand built GM rotary engines, and was painted a metallic Turquoise. The car was disassembled when the GM rotary program folded, and the GM rotary engine was returned to Chevrolet.
