. Its two unique features are its use of car and truck tires as flow diverters and its shallow slope, closer to 1% than the usual nearly 2% for such venues. Despite these characteristics, the Troja facility has hosted ten World Cup races and one World Championship in the 21 years 1992–2012, and the 2013 World Championships.
