The first time we saw a car do a corkscrew was when Jeremy Clarkson from Top Gear pulled some G’s in a Renault Twingo in a tunnel in Belfast. Now, the folks at Mercedes-Benz have performed the same feat using their new supercar, the SLS AMG Gullwing. Whether or not this video is real is debatable. The SLS seems to maintain some pretty excessive hangtime upside down. We’ll have an update if there is ever confirmation, but for now just enjoy the footage after the jump.
