We love this stunt from Mattel!
Mattel created a life-sized replica of their Hot Wheels toy car circuit and set a Guinness World Record at the X-Games in Los Angeles this month.
The stunt is part of a series of episodes that are being released on the Hot Wheels website, where drivers, Tanner Foust and Greg Tracy, show off their skills by lining up to challenge the impressive six-story double vertical loop.
