No automaker is immune to global environmental pressures to reduce pollutants and limit carbon dioxide emissions. Even Porsche has gotten into the green game with both diesel and hybrid options for its Cayenne along with an expected hybrid powertrain for its Panamara range. Could that fuel-saving technology make a move closer to Porsche's sportscar roots? If so, would the battery pack go under the front hood in the rear-engined car?

According to a series of spy photos from our friends at NextAutos, the answer to those questions may be yes and yes. Although there aren't any logos on the car – save for some awesomely well-placed Batman stickers (Are we looking at the next Tumbler?), the bodystyle undoubtedly screams 911 while the details have us scratching our heads. What's with the oddly shaped bulge (complete with what appears to be a lightning bolt graphic) on the hood, or the fact that the photogs claim the car made virtually no noise as it sped away at high velocities?

For what it's worth, in addition to the hybrid Cayenne and Panamera programs, we also know that the German automaker is keenly interested in electric vehicles, including its iconic 911. In other words, these are spy shots that have our interest piqued even more than usual.
