Like the more recent Maserati Birdcage, Italian automakers have a tradition of going above and beyond when it comes to building sports prototypes, even if they are never intended to function. Pininfarina unveiled the most exotic of their concepts at the 1970 Geneva Motor Show. Built on a 512S racing chassis, powered by a high revving 550 HP V12 that can be admired through the 24 oversized holes in the engine cover. This mid-engine concept was the last in a series by the Italian automaker, the 512 featured a canopy style windshield that opened forward, forcing the occupants to exit through the large opening, like in the Lancia Stratos. Unfortunately the wheels on the Modulo concept were streamlined into the bodywork, this made it nearly impossible for the 1970s concept to turn.
