In a bid to get that same group excited about the new Dodge Dart, Chrysler enlisted Travis Pastrana to pilot its Global RallyCross entry. And in a sort of low-budget, less-elaborate version of Block's wacky-upon-zany Gymkhana videos, Pastrana puts the Dart through its paces, losing the passenger-side rear corner of the bodywork in the process.
