Years ago, when reading about the Saleen S7 supercar, our mental jaws were dropped by one particular info-tidbit. Seems as if the ground effects and aerodynamics on the S7 created so much downforce at speed that you could drive it upside down! Likely? Let's just say no. But a fantastic mental image nonetheless.
But surely no one would be crazy enough to actually, you know, drive a car upside down, right? Mr. skeptic, meet Mercedes-Benz. Or more specifically, meet the SLS AMG gullwing supercar, which does its best Lionel Richie impersonation in the video after the jump.
The obvious question is whether this is real? Internal Autoblog opinion is sharply divided. Some of us feel that sure, given the right conditions plus luck and one hell of a driver you very well could drive this car upside down. Others are screaming, "fake!" Still others are on the phone with in-the-dark Daimler PR folks trying to get a straight yes or no answer. All we know for sure is that, "marbles don't need no downforce." And yes, Top Gear did it first, we know. Videos can be found after the jump.
