Penske Entertainment CEO Mark Miles says the organization that owns the NTT IndyCar Series is looking into the formation of an international barnstorming tour that would run during the downtime between championship seasons.

For Miles, who has tried to land a new international event for the series since joining IndyCar more than a decade ago, the efforts to bring the series back to the world’s stage have been consistently unsuccessful, including recent attempts to bring the American open-wheel championship to Argentina. Other international options have also failed to bear fruit since his arrival late in 2012, but the 71-year-old executive remains undeterred.

And rather than continuing to focus on finding a single international race outside of IndyCar’s immediate borders in Canada or Mexico, Miles says Penske Entertainment is contemplating going bigger with a multi-race global tour during the series’ six-month offseason.

“First of all, if it were to happen, Mexico would be part of the NTT IndyCar championship points race – a drive to there from somewhere like Long Beach, or vice versa; part of the championship in the regular season,” Miles told RACER.

“So I don’t even think of it as ‘international’ in that context. I do think ending at the end of August, we’ve got an opportunity to have a productive period of time for IndyCar teams and our promotion of an ‘IndyCar International Series.’”
