Formula 1 gets a taste of dirt-track racing

It's not often that one sees a Formula 1 car purposely take to the dirt.

But Red Bull, ever the promoters of the unorthodox, did just that in showing how its world championship-winning car performs on the under-construction Circuit of the Americas in Austin, Texas, which will host a Formula 1 race next year. And by "under construction," we mean dirt, a long way from the smooth asphalt that make F1 cars the most fearsome on Earth.

World of Outlaws, you have nothing to fear.
