Known as America's National Park of Speed, this historic 4 mile natural terrain road course is one of the world's fastest permanent road racing circuits. It has hosted races since the 1950's and currently hosts racies from IndyCar, IMSA, GT World Challenge, Trans-Am and MotoAmerica superbike. Road America is one of only a handful of road circuits in the world maintaining its original configuration being 4.048 mi in length with 14 turns. The track features many elevation changes, along with a long front stretch where speeds approaching 200 mph may be reached. One of the best known features of this course is a turn on the backside known as "the kink". Having been there myself, I can assure you it is more of corner than a kink.
