Looks like Iowa's going to go back to being a day race. Wonder if they'll do the heat races this time.
Answering my own question, via Indycar's official website
Three 50-lap heat races, including transfers to Race 3 for the top two finishers in the first two qualifying races, will determine the starting grid for the seventh Iowa Corn Indy 250 on June 23 at Iowa Speedway in Newton, Iowa.
The format for heat race qualifications on June 22 also will reward 12 starters with points – from nine points for the pole winner and descending by one point each position to one point for 11th and 12th. Other IZOD IndyCar Series events, outside of the Indianapolis 500 with its own points framework, pay one point to the pole winner.
With the ability to race your way into the top heat, this is pretty much what drivers asked for. Paying points for the final grid positions might make things a little racier too.
