It's time for today's flash of Citroen side-boob as the French automaker teases us with yet another glimpse of the GT Concept set to debut at the Paris Motor Show next month. Here we have a rear three-quarter shot showing knife-edge taillights, a continuation of the gaping lower-body ductwork and some pretty meaty looking decklid gills. We'll go ahead and draw the logical conclusion that Citroen's supercar has a mid-mounted engine — we're just not sure what kind. Judging by those huge lower vents, we're thinking gas turbine. Huge, afterburning gas turbine. [via WCF]
