Two drivers have broken a world record by hurling themselves around a real-life Hot Wheels 'Double Loop' stunt course at the X Games in Los Angeles.
Tanner Foust and Greg Tracy drove at 52mph to make it around the 66ft-high loops.
They smashed the record for the previous highest loop, which stood at 42ft.
The drivers said they experienced seven Gs while travelling the course.
"That was pretty hardcore: the seven Gs ... I almost felt my chin hit my lap, I think, in the loop," said Tanner Foust. :I felt like I was in a toy."
The stunt - which also included a jump after the double loop itself - had taken about a year of planning and training.
They were watched by thousands of spectators at the X Games extreme sports competition.
