IndyCar and NASCAR leaders signal more shared weekends after Phoenix doubleheader

Executives from IndyCar and NASCAR have pointed to the success and fan appeal of shared racing weekends, speaking at the Autosport Business Exchange in New York. The two series' collaboration is described as continuing to look promising.

The partnership drew attention earlier this year with a "Desert Double" weekend at Phoenix Raceway in March, which brought both championships together on one programme. Officials at the event said there is more to come from the arrangement.
