In 2000, Ascari began developing a racetrack near Ronda, in southern Spain. The track includes recreations of famous corners from other tracks around the world, and may be set up as one long track, three separate short tracks, or some combination in between. By 2002 the three part track was finished and accompanied by a high-end resort, with several road and racing cars available to visitors to test, including former Formula One machinery.
