To give you some context here, a barrel roll is normally achieved when a plane rolls along its longitudinal axis in mid flight. How exactly did Cenni achieve this feet in a non-aircraft? With the help of a pair of ramps - and little bit of luck - Cenni got an extra-special lift that kicked his car into the air and tilted it into the roll. In a scene that seemed to defy gravity, Adrian was able to twist the vehicle all the way around and landed hard on packed dirt.
Seems pretty safe to say 'Wildman' won't be losing that nickname any time soon.
