Touring car series proliferate in countries around the globe. The UK has the British Touring Car Series, Germany has DTM, Australia has V8 Supercars, Japan has Super GT and Italy has the Superstars Series.
International Superstars Series
We'll forgive you if you haven't heard of the Superstars Series. It's only been around since 2004 (the International category since 2007) and all of the races take place in Europe – in fact over half took place this season in Italy. But similar to other national touring car championships – Germany's DTM, Japan's Super GT and Australia's V8 Supercars come to mind – the Superstars Series packs some serious racing machinery.
