Sitting down with former F1 star and current IWC ambassador David Coulthard

Ahead of Sunday's Miami Grand Prix, Coy Wire caught up with David Coulthard to discuss his continued involvement in F1 and the "IWC Chrono Challenge," which was organized in collaboration with Miami-based non-profit charity, Dibia DREAM. Coulthard talks about the continued evolvement of F1 from his career until now, and it's future with women seeking to break onto the scene and more US based races popping up.
