(AP) The pair...a rally car driver and a stuntman - spun upside down driving around in two life-size Hot Wheels racing cars!!
A fearless driving duo has set a new world record by racing two life-size Hot Wheels racing cars through a 66ft double vertical loop based on a toy set.
Rally car driver Tanner Foust and Hollywood stuntman Greg Tracy appeared to defy gravity as they reached speeds of 53MPH spinning around the 360 degree double ramp.
The pair pulled off the incredible feat on the six-storey high track, modeled on the Mattel Hot Wheels double loop, at the 2012 X Games in Los Angeles.
Both Foust and Tracy, who made up Team Hot Wheels with a crew of engineers, scientists and stuntmen, rode across the length of two football fields on the orange tracks.
"I tell you what, I'm at a loss for words. That was absolutely the coolest thing I've ever done," Tracy said after the race.
"'It was a handful trying to land it and get it slowed down.
"I knew Tanner was right behind me and I was just hoping we weren't going to tangle before we got to the end."
The previous world record for such a stunt was set in September of 2011 by Chinese driver Li Yatao who made a 42ft loop in a Lotus 5 Sportback in Shanghai.
During their daredevil drive on Saturday, Foust and Tracy experienced the same G-force fighter jet pilots experience in flight.
"That was pretty hard core: the 7 Gs ... I almost felt my chin hit my lap, I think, in the loop," Foust said.
But the three-time X Games Gold medalist and two-time Formula Drift Champion revealed his secret to not passing out.
"Grunt, tighten your core and try to make your eyeballs and veins pop out," he said.
Last year at Indianapolis 500 Foust earned Hot Wheels a coveted world record-breaking distance jump.
Meanwhile, Tracy is a successful stuntman has been doing stunts for movies and commercials for 11 years.
