GP2 Asia Series?
50% of which was in Italy? All that GP2 Asia is is an extended test session in the Gulf States for the Real GP2 season. Plus, only 2 of the drivers (or 1, if you don’t count Russia, of which the important bits are in Europe) were from Asia anyway.
But according to Wikipedia, India has Formula Rolon, Formula LGB Swift, Formula LGB Hyundai & Formula Maruti, then there’s the Pan-Asian Formula BMW Pacific Series, and Formula Nippon in Japan.
Still, it’s hardly Europe or the Americas though.
