R+S Project was in charge to create and develop Circuit Design for a street race in Porto. In 2005 it was a National Homologation and then an upgrade was required to allow a FIA WTCC round. In 2007 the Circuit was upgraded (FIA homologated) and the first WTCC round occurred in Porto. In 2009, 2011 and 2013, WTCC returned to Porto and track has been always improved from one round to the other.
