# Superstars Series

The Superstars International Series was a production-based touring car racing championship held between 2004 and 2013. It was 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.
After the shutdown of the promoter SWR in late 2013, the competition has been re-branded as EuroV8 Series and organized by FG Group and ATT (Associazione Team Top cars). SuperTouringSeries is going to be performed by Pan Asia Racing Enterprise Ltd. (PARE Ltd) in 2015. However, it has been cancelled.
The new championship’s identity, partners, teams, sporting regulations and calendar was unveiled at the Autosport International show in January 2014.

## History

The series began in 2004 as Trofeo Nazionale Superstars (Superstars National Trophy) with a six race schedule, all the events held at Italian tracks. The initial field was made of BMW M5 and Jaguar S-Type models, entered by five teams.
From 2005 the series became the Campionato Italiano Superstars (Italian Superstars Championship), and soon became the main tin-top auto racing series of the country, replacing the Italian Superturismo Championship (folded in 2007).
In 2007 the series started to visit circuits in other European countries as the FIA approved International Superstars Series. Since then 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.
With the 2010 season a new series was added, the International GTSprint Series allowing GT2, GT3 and nationally-homologated GTs. Uniquely, however, it has two 25 minute sprint events per weekend rather than the usual two-driver, long-distance runs that are the norm in GT competition.
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.
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 GT Sprint 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 2 to take place Sunday afternoon.
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.
