The Superstars International Series is a production-based touring car racing championship held since 2004. It is managed by the "Superstars World of Racing SpA", SWR, a company of FG GROUP with headquarters in Rome and sanctioned by the Automobile Club d'Italia (ACI) and the Commissione Sportiva Automobilistica Italiana (CSAI). FG GROUP, led by Maurizio Flammini, is famous for having promoted the FIM World Superbike Championship from its beginnings in 1988 until its sale to Infront Sports & Media in 2007.
For 2013, the series will race in 6 countries across 8 race weekends and 16 sprint races.
The series began in 2004 as Trofeo Nazionale Superstars (Superstars National Trophy) with a six race schedule, all the events held in Italian tracks. The initial field was made of BMW M5 and Jaguar S-Type models, entered by five teams.
Since 2005 the series earned the Campionato Italiano Superstars (Italian Superstars Championship) title, and soon became the main tin-top auto racing series of the country, replacing the Italian Superturismo Championship (folded in 2007).
International Expansion 
2007: In 2007 the series started to visit circuits in other European countries and in the same year became the FIA approved International Superstars Series. Every season awards two different drivers' titles, one for the International Series and one for the Italian Championship. Points are gained for the Italian Championship at each Italian and one European race meeting. Since the launch of the International title and calendar, the series has grown in participation from teams and public as well as in media value.
2012: The 2012 season saw the growth of the series in terms of media and spectators - attracting 33,000 fans to its race at Vallelunga in Rome on October 7, 2012. Johan Kristoffersson won the championship in his KMS Audi RS5 after a season long battle with Vitantonio Liuzzi and his CAAL Racing Mercedes AMG C63. Kristoffersson's success in SUPERSTARS proved a strong element in advancing his career.
2013: The 2013 calendar contains eight races in 6 countries. The series promoters have given the series an umbrella name "THE SUPERSTARS WORLD OF RACING" that reflects its international growth and refers to the entire weekend of events which includes The SUPERSTARS INTERNATIONAL SERIES, the GTSPRINT INTERNATIONAL SERIES, local support races and entertainment events.
Format and Philosophy 
Since 2009 the Series has run a two sprint race format. Race 1 to take place Sunday morning and Race two to take place Sunday afternoon.
After its success with World Superbikes, FG GROUP applied a similar motorsport marketing philosophy to the SUPERSTARS INTERNATIONAL SERIES. The technical regulations are designed to bring the largest touring cars together in a balanced competition that limits costs, maximizes spectacle and limits driver assistance. A total of 10 brands will be represented in the 2013 edition: Audi RS5, BMW M3, Cadillac CTS-V, Chevrolet Lumina and Camaro, Chrysler 300C SRT8, Jaguar XF, Lexus ISF, Maserati Quattroporte, Mercedes C63AMG, Porsche Panamera. Key values of the Series promoted by FG GROUP are: "The Best Motorsport Show", "Great Champions and F1 Stars", "World Wide TV", "Paddock Entertainment" and "Premium Partnerships"
