The X Games is known for feats of the 'extreme' variety. But this is something new.
On 30 June at the X Games LA 2012, two drivers will accelerate simultaneously around a 66-foot tall double loop-the-loop.
In a live recreation of the famous Hot Wheels double loop toy, former Formula Drift champion Tanner Froust and stunt driver Greg Tracy will drive at 52 miles per hour, and experience seven Gs as they loop-the-loop and arrive together in the middle.
"The Hot Wheels Double Loop Dare is a great addition to the X Games experience," said Tim Reed, ESPN senior director of content strategy.
"We're excited about our relationship with Hot Wheels and adding this entertainment spectacle to an exciting four days of world-class action sports competition in downtown Los Angeles."
