Feast your eyes on the most holey of Porsches. Ba-dump ching. Actually this "transparent" Porsche Cayenne that seems to be doing a passable impression of swiss cheese is actually a rolling laboratory developed to test electronic equipment in real world conditions. It's meant to test not only equipment for the Cayenne, but other Porsche vehicles as well up to a full year before drivable prototypes are even available. This allows Porsche engineers to work out the bugs way ahead of time. There are numerous cutouts protected by clear plastic all over the exterior that allow access to various electronic components, while the interior has been completely gutted save for the driver's seat. I have so many more jokes that could be said of Porsche's "transparent" Cayenne, but I'll let you guys fill the Comments section with punchlines instead.
