Top Gear's already proved that it's perfectly possible to do a full 360-loop in a car just like that crazy Hot Wheels toy, but what about a double loop or "deadly 720"?
The Top Gear crew did the stunt live in front of a packed out audience in South Africa. Mind you, it wasn't an ordinary car, but it still had to maintain between 24 and 26mph to do the loop for both of them. Pretty impressive, especially from the on-board feed. They broke a world record too, not bad for a day's work. [Top Gear via Jalopnik]
